2006 Chevrolet Colorado Electrical Problems

Your truck caught fire in the engine bay involving the wiring and fuse box while parked with the engine off. The dealer examined it but claimed it wasn't a factory defect and wouldn't provide you with details, citing confidentiality. This suggests a potential electrical short or wiring issue in the engine compartment that may require a complete electrical system inspection and possibly replacement of damaged wiring harnesses and the fuse box.

Your truck's PassLock security system shut down your engine while you were driving and then prevented the truck from restarting for about 2 months. The security lock indicator displayed on your dashboard, but multiple mechanics couldn't reset the system despite diagnostic scans. The fix will likely require the dealer to use their computer diagnostic equipment to reprogram or replace the PassLock security module.

Your rear brake lights flicker or fail to illuminate when you press the brake pedal, and while driving at night your instrument cluster display goes dark so you can't see your speedometer or other gauges. This electrical issue affects both your brake light function and dashboard visibility, creating a safety concern when driving after dark.

Your truck won't start when it's hot outside. The vehicle becomes too hot to start reliably. This is likely an electrical or fuel system issue that gets worse in high temperatures and may require diagnosis of the starter, battery, or fuel pump system.

Your car's ignition security system (called PASS-LOCK) is preventing the engine from starting. This is a known issue affecting many vehicles. While the problem can be fixed, it typically requires dealer service at a significant cost.

Your truck's electrical system randomly shuts off while you're driving, causing the instrument panel and radio to go dark. However, the engine and headlights continue running normally. This intermittent electrical failure could leave you without dashboard information and audio while driving.

Your rear brake lights aren't turning on when you press the brake pedal. This has happened repeatedly — the brake light bulbs have been replaced eight times, but the problem keeps coming back, suggesting an underlying electrical issue rather than just bad bulbs. The dealership refused to continue servicing it, so you had it repaired elsewhere. The fix will likely involve diagnosing and repairing the brake light circuit wiring or electrical connections behind the tail lights.

PASSLOCK TRUCK WILLNOT START ONLY SITTING FOR FIFTEEN MINUTES ,HAD IT REPLACED ONCE 12/27/2013 NOW ITS DOING IT AGAIN I NEED THIS TRUCK BECAUSE MY WIFE IS VERRY SICK BUT I CANT DEPEND ON IT IT HAS UNDER 34,000 MILES ON IT.

TL* THE CONTACT OWNS A 2006 CHEVROLET COLORADO. WHILE DRIVING 25 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE CONTACT COASTED OVER TO THE SIDE OF THE ROAD AND WAS ABLE TO RESTART THE VEHICLE. THE VEHICLE WAS TAKEN TO A DEALER WHERE THE IGNITION SWITCH WAS REPLACED. IN ADDITION, THE PASSENGER SEAT BELT WARNING LIGHT WOULD REMAINED ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 50,000.

MY BRAKE LIGHTS ALL WENT OUT AT THE SAME TIME. I WAS DRIVING ON THE INTERSTATE AND HAD TO STOP SUDDENLY. THE TRACTOR TRAILER BEHIND ME NEARLY REAR ENDED ME. THE CRUISE CONTROL ALSO WENT OUT. I HAD THIS ISSUE REPAIRED UNDER RECALL NUMBER 06030 FIVE YEARS AGO. IT IS IDENTICALLY THE SAME, YET CHEVROLET SAYS THEY WILL NOT REPAIR IT DUE TO MILEAGE AND VEHICLE AGE. THIS IS EXTREMELY DANGEROUS.

POWER WINDOWS LOSS POWER, INCLUDING DRIVER AND PASSENGER WINDOWS. WIRING PROBLEM EXISTS. KEN DIXON, THE DEALER IN WALDORF, MD REPAIRED PROBLEM ON JANUARY 21, 2013 AT A COST OF $300 UNDER SO # 243247. BUT THE SAME PROBLEM REOCCURRED IN EARLY FEB 2016 AND THE DEALER REFUSED TO REPAIR THE PROBLEM WITHOUT COSTS TO THE CUSTOMER. THE VEHICLE WAS STATIONARY. THE PROBLEM MIRRORS RECALL OF THE SAME MAKE AND MODEL UNDER NHTSA'S CAMPAIGN #14V404.

TL* THE CONTACT OWNS A 2006 CHEVROLET COLORADO. THE CONTACT STATED THAT THE VEHICLE FAILED TO START UNTIL AFTER WAITING TEN MINUTES. THE FAILURE WAS RELATED TO THE FAULTY PASS LOCK CYLINDER. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 140,000.

HAZARD LIGHT STUCK ON, PREVENT USE OF SIGNAL LIGHT. WHEN DISABLED SIGNAL LIGHT NOT OPERABLE. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET COLORADO. THE CONTACT STATED THAT WHEN THE IGNITION SWITCH WAS TURNED INTO THE ON POSITION, THE VEHICLE WOULD MAKE AN IGNITING NOISE BUT WOULD NOT START. THE FAILURE RECURRED ON MULTIPLE OCCASIONS. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 47,000.

SOME TIMES THE TRUCK WILL NOT START FOR TEN MIN. I HAVE HAD THE TRUCK 3 TIMES STOP RUNNING AND HAD TO COAST OFF THE ROAD. IT RESTARTED AFTER SITTING WITHOUT REPAIR. *TR

HAVE EXPERIENCED PROBLEMS WITH MY TRUCK'S PASS LOCK/ANTI-THEFT SWITCH. THE TRUCK WILL NOT START AND IT TAKES TEN MINUTES BEFORE THE TRUCK RESTARTS. I HAD ONLY ABOUT 22,000 MILES ON THE TRUCK WHEN THE PROBLEM FIRST OCCURRED. THIS ISSUE CONTINUES TO BE A PROBLEM. THE TRUCK ON HAS 26,000 MILES. THIS PROBLEM COULD EASILY BECOME A SAFETY ISSUE IF TRUCK SHUTS OFF IN TRAFFIC. THERE SHOULD BE A RECALL. DOES SOMEONE HAVE TO DIE BEFORE A RECALL TO HAPPEN? *TR

I AM GOING TO GET GAS AND GO IN SIDE TO PAY AND IT WONT START CRANKS NO ADVISE I HAD THE SAME 5 TIMES BEFORE THE MIDWAY CHEVROLET FIX IT A BAD IGNITION SWITCH PART #63779 O A BILL FOR THE PARTS $416.74 THE THEFT SYSTEM WOULD WORK AND IT WOULD STOP WORKING IT IS A SWITCH FOR THE GAS I THINK I NEED TO BE PAY BACK. *TR

DRIVING ON US 441 ENGINE SHUT OFF AND THE PASS LOCK LIGHT CAME ON. HAD TO STEER OFF OF ROAD WITH NO POWER. RESTARTED AFTER STOPPED AND HAPPENED AGAIN COMING BACK UP MOUNTAIN BUT NO WHERE TO PULL OFF ROAD NEARLY HIT BY ANOTHER CAR. DEALER SAYS THIS IS A SECURITY SYSTEM TIED TO THE IGNITION SWITCH AND FUEL WHEN THE CAR IS STARTED BUT SHOULDN'T SHUT OFF FUEL WHILE DRIVING. ADMITTED THIS IS A COMMON PROBLEM THEY EXPERIENCE THOUGH. IF THE PASS LOCK SYSTEM FAILS TO WORK AS DESIGNED AND SHUTS OFF THE FUEL SUPPLY TO THE ENGINE WHILE DRIVING IT'S VERY DANGEROUS. SHOULD BE A RECALL TO REPLACE THE SECURITY SYSTEM WITH A SYSTEM THAT WORKS AS DESIGNED. *TR

TRUCK WILL JUST SHUT OFF AND NOT CRANK. PASSLOCK MODULE WILL NOT LET IT CRANK. AROUND EVERY 100 CRANKS IT WILL SHUT ENGINE OFF AND NOT LET IT CRANK. I HAVE DONE RESEARCH AND NUMEROUS PEOPLE HAVE HAD THIS PROBLEM WITH THESE TRUCK AND CHEVROLET COMPANY WILL NOT DO ANYTHING ABOUT THIS. THIS IS DANGEROUS IT HAS EVEN SHUT OFF WHILE DRIVING VEHICLE. CAN YOU PLEASE MAKE THEM FIX THIS ON THESE TRUCKS. *TR

THE VEHICLE WILL NOT START. THE ENGINE TURNS OVER HOWEVER THE VEHICLE WILL NOT START. AFTER FIFTEEN TO TWENTY MINUTES THE VEHICLE STARTS. TODAY MY 17 YEAR OLD DAUGHTER IS AT A FRIENDS HOUSE SOME DISTANCE AWAY AND THE VEHICLE WILL NOT START. I HAVE TAKEN THE VEHICLE TO MY MECHANIC AND HAVE DISCOVERED THAT THIS IS A KNOWN ISSUE WITH THIS VEHICLE. I AM SURPRISED THAT THERE HAS NOT BEEN A RECALL FOR THE IGNITION SWITCH BY CHEVROLET. I WOULD LIKE TO KNOW WHAT IF ANY OPTIONS I HAVE OTHER THAN TO TAKE MY VEHICLE BACK TO A CHEVROLET DEALER AND HAVE THEM INSTALL AND RE-PROGRAM THE COMPUTER SYSTEM TO THE NEW IGNITION SYSTEM WHICH BY THE WAY PER ALL OF THE SIMILAR COMPLAINTS I HAVE RECENTLY FOUND ON THE INTERNET IS DEFINITELY DEFECTIVE. I AM ALSO WONDERING IF THIS IS THE PRELUDE TO THE CURRENT IGNITION PROBLEM THE G.M REFUSED TO RECOGNIZE AFTER NUMEROUS COMPLAINTS THAT UNFORTUNATELY ENDED IN CAUSING NUMEROUS ACCIDENTS AND TRULY UNFORTUNATE DEATHS WHICH ALL WERE UNCALLED FOR. I HAVE RESEARCHED MY VEHICLE ON THE INTERNET AND HAVE FOUND NO RECALL OTHER THAN THAT OF A CHILD CAR SEAT ISSUE WHICH DOES NOT APPLY TO MY VEHICLE AS I HAVE TWO FOLD DOWN SEATS IN THE XTRA CAB. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET COLORADO. THE CONTACT STATED THAT THE VEHICLE FAILED TO START. THE FAILURE RECURRED ON SEVERAL OCCASIONS. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO REPLACED THE IGNITION SWITCH ON FOUR DIFFERENT OCCASIONS. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 60,000.

THE A/C BLOWER MOTOR STOP RUNNING ON SPEED SELECTIONS 1,2 AND 3. AFTER A FEW SECONDS IT STARTS RUNNING. ON SPEED SELECTION4 IT RUNS OK. I WAS TOLD THE RHEOSTAT IS FAULTY. *TR

THE PASSLOCK SYSTEM HAS BECOME MORE OF AN ISSUE WITH THIS VEHICLE. THE VEHICLE WILL NOT START ALMOST TWO TO THREE TIMES A WEEK. NOT ONLY DOES THIS COME AT THE MOST UN-OPPORTUNE TIME BUT NOW HAPPENS MORE OFTEN WHEN I HAVE LESS THAN A HALF TANK OF GAS. WHEN I PUT GAS IN, THIS DOES NOT HAPPEN AS MUCH. AFTER 10 MINUTES OR MORE TO WAIT FOR THE SYSTEM TO RESET. SOMETIMES THE LOCK LIGHT STAYS ON AFTER I START THE CAR. MY MECHANIC HAS HAD THE TRUCK IN 4 TIMES AND HAS NOT BEEN ABLE TO FIND WHAT IS WRONG. AFTER READING THIS POST, I SEE THAT I AM NOT THE ONLY ONE WITH THIS PROBLEM. I HAVE HAD TO WAIT UP TO 30 MINUTES SOMETIMES TO GET THE TRUCK STARTED AGAIN. HIS HAS BECOME MORE OF A PROBLEM. I HAVE NOT HAVE ANY OTHER MAJOR PROBLEMS AND HAVE OVER 90,000 MILES. SO FAR THERE HAS NOT BEEN A DANGEROUS SITUATION WHERE THIS PROBLEM HAS HAPPENED. BUT IT GETS TO A POINT THAT YOUR AFRAID TO TURN THE ENGINE OFF. THANK YOU FOR YOUR TIME. *TR UPDATED 1/23/2015*JS

ONCE STARTED ONCE IN AWHILE IS HAPPENING MORE OFTER I PARK MY CAR AT WORK SUPERMARKET ETC AND THE CAR WILL NOT START I BELIEVE ITS THE THEFT PROTECTION THE LOCK LIGHT GOES ON AND I NEED TO WAIT 10 TO 15 MINS BEFORE THE CAR WILL START AGAIN JUST TONIGHT I WAS GOING HOME FROM WORK STOP TO GET GAS AND HAD TO WAIT AGAIN BEFORE THE CAR STARTED AND JUST A FEW DAYS AGO LAST SUN I HAD THE SAME PROBLEM AT THE STORE AND I HOPE IT STARTS BEFORE THE FOOD GOES BAD BEEN LUCKY IT LEAST 10 MIN AND THE MOST UP TO 20 MIN I GOT A RECALL LETTER AND WONDER IF THAT WAS THE PROBLEM THANKS FOR UR TIME. *TT

VEHICLE PURCHASED NEW ON 05/2006. LESS THAN A MONTH AFTER PURCHASE THE VEHICLE WOULD NOT START DUE TO PASSLOCK SYSTEM BELIEVING THE CAR WAS IN THE PROCESS OF BECOMING STOLEN. OWNER WOULD UNLOCK VEHICLE WITH KEY FOB AND PLACE KEY IN IGNITION TO START, BUT RED LOCK ICON ON DASHBOARD WOULD BLINK AND ENGINE WOULD NOT TURN OVER. ORIGINAL KEY AND ORIGINAL KEY FOB USED AT ALL TIMES OF OCCURRENCE. OWNER WOULD HAVE TO WAIT TEN MINUTES AND TRY AGAIN IF VEHICLE WOULD NOT START FOR PASSLOCK SYSTEM TO DISENGAGE. WHILE UNDER WARRANTY, CUSTOMER BROUGHT VEHICLE INTO GM DEALER MULTIPLE TIMES AND THE PROBLEM COULD NOT BE VERIFIED. THIS LEFT CUSTOMER STRANDED IN MULTIPLE LOCATIONS AT TIMES AND IN SITUATIONS THAT COULD HAVE LEFT OWNER IN A DANGEROUS SITUATION BASED ON AREA. AT ONE POINT, CUSTOMER COULD NOT START VEHICLE AFTER A HALF HOUR, HE THAN CALLED GM AND HAD THE VEHICLE TOWED UNDER WARRANTY, THE GM DEALERSHIP STATED PROBLEM WAS FIXED OR CORRECTED. NOW, NO LONGER UNDER WARRANTY VEHICLE HAS SAME ISSUE OCCURRING INTERMITTENTLY. COST TO REPLACE PASSLOCK SENSOR IS TOO COSTLY FOR OWNER TO AFFORD. OTHER VEHICLE MAINTENANCE IS PROPERLY DONE ACCORDING TO OWNER'S MANUAL BY LOCAL MECHANIC. OWNER HAS UPLOADED VIDEO OF ISSUE EXPERIENCING; PLEASE VISIT YOUTUBE AT HTTPS://WWW.YOUTUBE.COM/WATCH?V=MFDJHO_HIY4&FEATURE=YOUTU.BE. *TR

ON OCCASION, MY VEHICLE WILL NOT START. IT APPEARS THAT THE ANTI-THEFT SYSTEM COMES ON AND WILL NOT ALLOW THE VEHICLE TO START. LETTING THE VEHICLE SIT FOR TEN MINUTES TENDS TO FIX THE PROBLEM. MY VEHICLE HAS APPROXIMATELY 65K MILES AND THIS OCCURS ROUGHLY SIX TIMES A YEAR. WHEN THE DEALER TRIES TO IDENTIFY THE PROBLEM, THEY CANNOT FIND ANYTHING WRONG WITH IT.

I PURCHASED THIS VEHICLE NEW, AND FOR TOO MUCH INFORMATION THE VEHICLE IS A PIECE OF JUNK. ABOUT A COUPLE OF MONTHS AGO I UNLOCK MY VEHICLE USING THE REMOTE OPENER. GET IN THE VEHICLE, PUT KEY IN IGNITION, TRY AND START VEHICLE. VEHICLE WILL NOT START, THE ENGINE WILL TURN OVER, BUT WILL NOT START. I NOTICED DURING THIS TIME, WILL TRYING TO GET VEHICLE TO START, THAT THE ANTI-THEFT LOCK LIGHT HAS LIT UP ON DASH BOARD. TO NO AVAIL THE VEHICLE WOULD NOT START. AT THIS TIME I WAS NOT AWARE OF ANY PROBLEMS WITH VEHICLE, SO I THINK HERE WE GO ANOTHER TRIP TO THE DEALER TO GET PIECE OF JUNK FIXED. AFTER I HITCH A RIDE HOME, I SEARCH THE WEB FOR ANY REASONS VEHICLE WILL NOT START. I FOUND ARTICLES FROM INDIVIDUALS WHO ALSO HAD THIS SAME PROBLEM. I LEARNED FROM ONE THAT FOR SOME REASON THE VEHICLE'S ANTI-THEFT SYSTEM THINKS YOU ARE TRYING TO STEAL YOUR OWN VEHICLE. I ALSO LEARNED THAT IF YOU WAIT 10 MINUTES AFTER YOUR FIRST FAILED ATTEMPT AT STARTING VEHICLE THE ANTI-THEFT WOULD RESET ITSELF AND VEHICLE WOULD START. TRY TO START THE VEHICLE THE NEXT MORNING, AND IT STARTS. I THINK OKAY I WILL STOP USING REMOTE AND NOT LOCK VEHICLE, SEE IF THIS STOPS PROBLEM. IT DOES NOT. I GET IN VEHICLE ABOUT 2 DAYS AGO AND AGAIN THE ENGINE WILL TURN OVER, BUT WILL NOT START. THERE IS THE ANTI-THEFT LIGHT LIT UP ON DASH BOARD AGAIN. THIS TIME I WAIT 10 MINUTES AND THE VEHICLE WILL START. I HAVE CALLED THE DEALER AND GM, FROM BOTH I HEAR THERE IS NO SOLUTION. CAN'T BY-PASS THE ANTI-THEFT, AND FOR SERVICE DEPT. TO FIND PROBLEM, VEHICLE HAS TO EXPERIENCE SAME PROBLEM AT THE TIME OF REPAIR. SINCE THE PROBLEM IS INTERMITTENT, A SOLUTION IS UNLIKELY. THERE APPEARS TO BE A PROBLEM WITH THIS TYPE VEHICLE, BUILT AROUND THE TIME FRAME AS THE PURCHASE OF THE ONE I BOUGHT. GM SHOULD BE MADE TO FIND A SOLUTION. I DO NOT LIKE BEING STRANDED, AND SELLING THE PRODUCT TO SOMEONE ELSE IS NOT AN OPTION. *TR

THE PASSLOCK SYSTEM IS AN ISSUE WITH THIS VEHICLE. THE VEHICLE WILL NOT START ON OCCASION, OR IN MY CASE SEVERAL OCCASIONS. NOT ONLY IS IT INCONVENIENT, BUT I ASK, WHAT HAS HAPPENED TO PEOPLE WHO HAVE STALLED WITH THIS VEHICLE AT STOP LIGHTS OR IN OTHER SITUATIONS? I LIVE IN AN AREA WHERE THE WEATHER CAN DROP TO -30 (F). 10 MINUTES TO WAIT FOR THE SYSTEM TO RESET CAN HAVE DETRIMENTAL EFFECTS. HOW MANY FATALITIES AND INJURIES WILL IT TAKE BEFORE GM AND THE NHTSA ACT? THIS IS A SAFETY ISSUE AND IT NEEDS TO BE ADDRESSED. OUR TAX DOLLARS BAILED OUT GM, I EXPECT A PRODUCT THAT WILL NOT PUT ME IN A DANGEROUS SITUATION. THANK YOU FOR YOUR TIME. *TR

I OWN A 2006 CHEVY COLORADO EXTENDED CAB. THE AIR BAG READINESS LIGHT STAYED ON AFTER STARTING THE VEHICLE. ACCORDING TO THE MANUAL, IF THE AIR BAG READINESS LIGHT STAYS ON AFTER YOU START THE VEHICLE, IT MEANS THE AIRBAG IS NOT IN WORKING ORDER. THE AIRBAGS MAY NOT INFLATE IN A CRASH OR THEY COULD INFLATE WITHOUT A CRASH. THIS IS A SAFETY PROBLEM. I AM CONCERNED THAT THE AIRBAG WOULD NOT DEPLOY IF INVOLVED IN A CRASH. I AM ALSO CONCERNED ABOUT HAVING THE AIR BAG DEPLOY UNDER NORMAL DRIVING. THERE IS A WIRING HARNESS THAT TRAVELS THROUGH THE HINGE OF THE REAR DOOR THAT APPEARS TO BE A PROBLEM. THE OPENING AND CLOSING OF THE REAR DOORS HAS CAUSED THE WIRES TO BREAK. THIS REAR DOOR GETS OPENED MAYBE 1 OUT OF EVERY 10 TIMES THE VEHICLE IS ENTERED/EXITED. SINCE THE PROBLEM INVOLVES THE AIRBAGS I THOUGHT IT WOULD BE BEST TO TAKE IT TO THE DEALERSHIP FOR THEM TO REPAIR. SINCE THERE HAS NOT BEEN AN RECALL ISSUED, I HAVE HAD TO PAY FOR THIS MYSELF. *TR

AFTER MY VEHICLE GAINED 67XXX IT BEGAN TO HAVE ISSUES WITH THE ANTI THEFT SYSTEM. WHEN I TURN MY VEHICLE OFF, AND TURN IT BACK ON THE ANTI THEFT LIGHT BLINKS. THIS HAS STALLED MY VEHICLE. WHEN I ATTEMPT TO TURN IT ON THE ENGINE WILL CRANK AND THE LIGHTS FLICKER ON AND OFF. AFTER DOING SOME RESEARCH I HAVE FOUND THAT NUMEROUS PEOPLE HAVE ALSO ENCOUNTERED THIS ISSUE. THE ONLY FIX KNOW AT THE MOMENT IS TO WAIT 10 MINUTES AND THEN THE ENGINE WILL START. THIS CAN BECOME A NUISANCE AND A DANGER. I HAD RECENTLY ENCOUNTERED A NAIL IN MY TIRE. I HAD TO PULL OVER ON THE HIGHWAY TO CHECK WHAT WAS HAPPENING. WHEN I SHUT MY ENGINE OFF I WAS STUCK ON THE HIGHWAY DUE TO MY ANTI THEFT LIGHT BLINKING AND MY ENGINE NOT STARTING DUE TO THIS ANTI THEFT ISSUE. I HAVE ADDRESSED THIS WITH GM AND ALSO THE LOCAL DEALER WITH NO SUCCESS FOR ASSISTANCE. IT WAS SUGGESTED THAT I DO A DIAGNOSTICS TEST, BUT THAT WOULD RUN ME UPWARD OF 400+ TO FIGURE OUT WHAT IS GOING ON. I FIND THIS TO BE A MANUFACTURE ISSUE. NUMEROUS PEOPLE HAVE ADDRESSED THIS ISSUE ONLINE. *TR

AS I SEE I AM ONE OF MAY PEOPLE WITH THIS ISSUE, I AM HAVING ALMOST DAILY PROBLEMS WITH THE PASSLOCK/NO START FOR THE PAST FEW WEEKS. THIS HAPPENED ONE OTHER TIME BACK IN JUNE 2012 BUT HAS NOT DONE SO SINCE. THEN ABOUT 3 WEEKS AGO, IT STARTED DOING IT DAILY. I ATTEMPT TO START IT (WHETHER IT HAS BEEN SITTING FOR HOURS OR ONLY A FEW MINS), BUT IT ONLY WILL CRANK NOT START. I HAVE TO SIT IN THE TRUCK FOR ABOUT 10 MINS WITH THE KEY TURNED TO THE ON POSITION AND THEN IT WILL START. THIS IS RIDICULOUS. WITH SO MANY PEOPLE HAVING THIS PROBLEM, GM SHOULD BE FORCED TO PUT OUT ON RECALL ON THE PASSLOCK/SECURITY AND FIX THESE KNOWN PROBLEMS!! THIS COULD BE VERY DANGEROUS IF SOMETHING WERE TO HAPPEN WHERE YOU NEED TO MOVE YOUR VEHICLE IN CASE OF AN EMERGENCY AND IT WON'T START. *TR

I WAS DRIVING HOME FROM WORK DURING THE NIGHT-TIME HOURS AND BOTH HEADLIGHTS QUIT WORKING. NOW, THE LEFT HEADLIGHT CONTINUES TO GO OUT BUT I CAN TOUCH IT AND IT WILL COME ON. I HAVE REPLACED THE LIGHT SEVERAL TIMES AND NOTHING WORKS. ALSO, 1 WEEK AGO, THE ABS FAILURE MESSAGE APPEARED. THERE ARE MULTIPLE COMPLAINTS WITH THIS PROBLEM AND FRANKLY, BOTH OF MY ISSUES ARE SAFETY CONCERNS. GM HAS INSTALLED DEFECTIVE PARTS AS USUAL AND NOW THE CUSTOMERS ARE BEARING THE COST OF REPAIRING THEIR FAILURES. THESE ARE SAFETY CONCERNS THAT NEED TO BE RECALLED. I HAVE RECENTLY HAD THE INTAKE VALVE SEATS REPLACED BECAUSE OF A GM DEFECTIVE PART. THIS ABS FAILURE CONCERN IS MY NUMBER 1 CONCERN AS I HAVE VERY SMALL CHILDREN. *TR

THIS VEHICLE HAS AN INTERMITTENT CRANK NO START ISSUES, AS I HAVE RESEARCHED THESE VEHICLES HAVE PROBLEMS WITH A SECURITY SYSTEM KNOWN AS PASSLOCK, AS I SEE THERE IS KNOWN ISSUES WITH THIS FAULTY SYSTEM, YOU ATTEMPT TO START IT, BUT IT ONLY WILL CRANK NOT START. THE ONLY THING YOU CAN DO IS TURN THE IGNITION KEY TO THE ON POSITION FOR AT LEAST 10 MINUTES AND LET THE SECURITY RE-LEARN CODES BEFORE YOU CAN START THE TRUCK. I THINK G.M. SHOULD BE FORCED TO FIX THERE KNOWN PROBLEMS WITH THIS, AS IT COULD BE DANGEROUS BASED ON A SITUATION WHERE YOU NEED TO MOVE YOUR VEHICLE IN CASE OF AN EMERGENCY AND IT WONT START. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET COLORADO. THE CONTACT STATED THAT THE VEHICLE FAILED TO START. THE CONTACT STATED THAT HE TURNED THE KEY AND THE ENGINE WOULD NOT START BUT WHEN HE RELEASED THE KEY, THE VEHICLE STARTED INDEPENDENTLY. THE VEHICLE WAS TAKEN TO A DEALER FOR INSPECTION HOWEVER, THE TECHNICIANS DID NOT LOCATE A FAILURE WITHIN THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED BUT PROVIDED NO ASSISTANCE. THE FAILURE MILEAGE WAS 78,000.

PASS LOCK ANTI THEFT SYSTEM INTERMITTENTLY ENGAGES, PREVENTING THE VEHICLE FROM RESTARTING FOR A PERIOD OF 10 MINUTES. THIS PROBLEM IS A SAFETY ISSUE IF THE VEHICLE WERE TO STALL WHILE OPERATING ON A FREEWAY OR MAJOR HIGHWAY AND CAN NOT BE RESTARTED. *TR

I OWN A 2006 CHEVY COLORADO EXTENDED CAB. THE WIRING HARNESS THAT CONTROLS THE AIR BAGS, INTERIOR LIGHTS, AND STEREO SPEAKERS KEEPS BREAKING. I WAS TOLD THAT IT WAS A DEFECT FROM THE FACTORY. THE WIRES RUN BETWEEN THE CAB AND REAR DOORS. I HAD IT FIXED UNDER WARRANTY IN 2008 AND AGAIN IN 2009. MY WARRANTY EXPIRED RIGHT AFTER THE SECOND FIX. I HAVE HAD TO FIX IT MYSELF TWICE SINCE THEN. THIS IS A SAFETY ISSUE SINCE THE AIR BAGS ARE INOPERABLE WHEN THE WIRES BREAK. I AM SURE THERE ARE SEVERAL HUNDRED OF THESE TRUCKS ON THE ROAD WITH DEFECTIVE AIR BAGS SINCE MOST PEOPLE WILL NOT FIX IT. I WOULD EXPECT CHEVROLET TO EXTEND THE WARRANTY TO 100,000 MILES FOR THIS PROBLEM. I WOULD ALSO EXPECT GM TO CORRECT THE ISSUE SO IT DOESN'T HAPPEN AGAIN. *TR

VEHICLE AIR BLOWER FAN FOR HEAT/AIR CONDITIONER PERIODICALLY STOPS WORKING ON SETTINGS 1,2,AND 3. FAN CONTINUES TO WORK ON SETTING 4. *TT

BLOWER MOTOR ON MY 2006 CHEVROLET COLORADO QUIT WORKING EXCEPT FOR THE HIGH POSITION. LEAVING THE FAN IN THE HIGH POSITION TOO LONG WILL CAUSE THE FAN TO QUIT WORKING AND THEN THERE IS NO A/C , HEATER OR DEFOGGER THAT WILL WORK WHEN NEEDED. I TOOK IT TO THE DEALER WHO TOLD ME THAT HE KNOWS WHAT THE PROBLEM MAY BE, A RELAY OR THE WIRING HARNESS. AT A COST OF 328.00. HE TOLD ME OFF THE RECORD IF I WIGGLE THE WIRING HARNESS IT MAY WORK FOR A WHILE SINCE THE HARNESS MOST LIKELY WAS INCORRECTLY ROUTED.. I HAVE TALKED TO MANY COLORADO AND GMC CANYON OWNERS BOTH IN PERSON AND ON INTERNET FORUMS WHO REPORTED THAT THEY ARE HAVING THE SAME EXACT PROBLEM. THIS ISSUE COULD BE A SAFETY ISSUE ESPECIALLY IN THE WINTER TIME WHEN THE DEFOGGER IS REALLY NEEDED TO KEEP THE WINDOWS CLEAR FOR SAFE DRIVING. I INITIALLY THOUGHT THAT IT WAS JUST A SIMPLE BURNED OUT MOTOR , AND I WOULD JUST NEED TO REPLACE IT. BUT SINCE WHAT I WAS TOLD FROM THE DEALER SERVICE WRITER, AND WHAT OTHERS HAVE SAID IN THE FORUMS, I WOULD BE WASTING MONEY ESPECIALLY IS IT IS FROM A BAD WIRING HARNESS. I THINK GM SHOULD LOOK INTO THIS AND MAKE NEEDED REPAIRS. *TR

THE A/C HEATING FAN BLOWER DOES NOT WORK ON SPEEDS 1,2, OR 3, ONLY ON SPEED 4. AFTER DOING SOME RESEARCH, I FOUND IT IS RELATED TO THE FAN RESISTOR BURNING UP. I INSPECTED MY TRUCK AND FOUND THE SAME PROBLEM. THE PLASTIC IS BURNT AND HAS STARTED TO MELT. THIS CAN CAUSE A FIRE IN THE CAB AND BE VARY DANGEROUS. THERE ARE NUMEROUS COMPLAINTS HERE, SO I FEEL THIS SHOULD BE INVESTIGATED. *KB

06 CHEVY COLORADO VEHICLE FAILS TO START AFTER SHUTOFF. PASSLOCK FAILURE. HAPPENS REGULARLY. STOPPED TO FIX A TIRE ON THE SIDE OF THE ROAD AFTER CHANGING THE TIRE IT WOULD NOT START. 4AM ON THE SIDE OF THE ROAD HAVING TO WAIT 10 MINS TILL IT REST SO I COULD START IT. HAPPENS ALL THE TIME. *TR

2006 COLORADO WILL NOT START, FAN ONLY WORKS ON HIGH SPEED, ALL EXTERIOR LIGHT FAILED AT SAME TIME, ALL STEREO COMPONENTS HAVE GONE OUT, DRIVER INFORMATION SYSTEM WAS FAULTY AND REPLACED, INSTRUMENT CLUSTER RANDOMLY NOT WORKING. ABS LIGHT RANDOMLY COMING ON. THESE ARE ALL OF THE MAJOR PROBLEMS THAT HAVE BEEN OCCURRING WITH THIS TRUCK. THE NON-STARTING IS THE IGNITION HOUSING MODULE, THAT GM IS AWARE IS A PROBLEM. I HAVE TRIED MANY MANY TIMES TO EXPRESS THESE PROBLEMS TO GM. THEY TELL ME THEY ARE UNRELATED AS THEY ARE ELECTRICAL COMPONENTS FOR DIFFERENT AREAS OF THE VEHICLE. MY RESPONSE HAS BEEN THEY ARE ALL ELECTRICAL COMPONENTS OF THE SAME VEHICLE. I HAVE READ A LOT OF ON LINE COMPLAINTS AND THEY ALL SEEM TO BE THE SAME PROBLEMS. GM NEEDS TO BE A STAND UP COMPANY, AND STAND BEHIND THEIR PRODUCT LIKE THEY KEEP TELLING ME THEY DO. THESE PROBLEMS ARE OCCURRING SOME MUCH NOW MY TRUCK WILL BE IN THE SHOP TWICE THIS MONTH FOR DIFFERENT ELECTRICAL REPAIRS. BOTH REPAIRS BILLS BEING IN EXCESS OF $300.00 - $500.00. IT IS VERY DANGEROUS TO HAVE THIS VEHICLE JUST DIE IN INTERSTATE TRAFFIC. *TR

MY CHEVY COLORADO HAS THE SAME ELECTRICAL PROBLEMS THAT I HAVE BEEN HEARING ABOUT. THE DEALER CAN NOT FIND THE PROBLEM AS IT IS INTERMITTENT. YOU NEVER KNOW WHEN IT WILL HAPPEN, BUT THE MOTOR WILL NOT START. I HAVE CHANGED THE START RELAY, AND RUN RELAY., BUT THAT DOES NOT HELP AFTER SITTING AWHILE IT WILL START. IT IS DANGEROUS AS YOU COULD BE ANYWHERE WHEN THIS HAPPENS. ALSO AT ANY TIME THE ABS WARNING LIGHT COMES ON FOR NO REASON, AND THEN GOES AWAY. I WANTED A TRUCK THAT I COULD TRUST. IT LOOKS LIKE A WILL NEVER BUY A CHEVY AGAIN UNLESS I GET THIS RESOLVED. *TR

VEHICLE FAILS TO START AFTER SHUTOFF. PASSLOCK FAILURE. HAPPENS REGULARLY. *TR

FAN CONTROL ONLY WORKS ON FAN SPEED 4. POSITIONS 1 THRU 3 DO NOT WORK. AFTER RESEARCH ON INTERNET FOUND THE INFORMATION ON THE GROUNDING BLOCK FOR THE FAN CONTROL CIRCUIT. CHECKED THE CONNECTOR FOR THIS AND FOUND CORROSION AND SLIGHTLY DARKENED CONNECTOR DUE TO HEAT BUILDUP DUE TO THE CORROSION. ALSO YOU CAN GET THE FAN CONTROL TO WORK ON ALL SETTINGS IF YOU MOVE THE WIRES AROUND ON THE CONNECTOR SO IT MAKES GOOD CONTACT BUT THIS IS ONLY A TEMPORARY FIX. THIS WILL BE COME WORSE AS TIME GOES BY AND IF THE HEAT BUILDUP IS HIGH ENOUGH IT COULD VERY POSSIBLY RESULT IN A FIRE IN THE CABIN OF THE VEHICLE... THERE ARE A HIGH NUMBER OF COMPLAINTS ABOUT THIS ISSUE AND THIS SHOULD BE INVESTIGATED FOR A POSSIBLE RECALL. *TR

PASSLOCK FEATURE ENGAGES AND THE ENGINE WILL NOT START. ENGINE TURNS OVER BUT THIS FEATURE BLOCKS FUEL FROM ALLOWING ENGINE TO FIRE. THIS HAS OCCURRED SEVERAL TIMES OUT OF THE BLUE. I TURN THE VEHICLE OFF WHILE GETTING GAS AND IT WON'T START, PASSLOCK HAS STRUCK! *TR

2006 CHEVY COLORADO WILL NOT START WITH PROPER KEY. WHEN ATTEMPTING TO START VEHICLE, IGNITION SWITCH MALFUNCTIONS AND WILL MAKE ANTI THEFT SYSTEM THINK VEHICLE IS BEING STOLEN. PROPER KEY IS BEING USED AND SPARE KEY HAS BEEN USED TO VERIFY PROBLEM. HAVE RESEARCHED INTERNET AND LOT OF THE CHEVY COLORADO'S ARE HAVING THE SAME PROBLEM NEW OR NOT. GM WANTS $400 TO FIX A CLEARLY FAULTY PART. *TR

I COULD HAVE WRITTEN THIS COMPLAINT SIX MONTHS AGO, BECAUSE THIS PROBLEM HAS BEEN GOING ON FOR AT LEAST A YEAR AND IS NOW BECOMING MORE FREQUENT. MY 2006 CHEVROLET COLORADO WILL TURN OVER BUT WILL NOT CRANK. I WAIT EXACTLY 10 MINUTES AND THEN IT WILL START. THIS IS NOW HAPPENING ABOUT TWICE A WEEK. WHEN I'VE TAKEN IT TO THE DEALER AT LEAST THREE TIMES, THE DEALER COULD NOT REPLICATE THE PROBLEM. ON THE THIRD TIME I HAD IT AT THE DEALER, I WENT TO PICK UP THE TRUCK AFTER BEING TOLD, ONCE AGAIN, THAT THEY COULD FIND NOTHING WRONG; WHEN I TRIED TO START IT, THE SAME THING HAPPENED. BY THE TIME THEY ROLLED THE COMPUTER TO IT, THE 10 MINUTES HAD PASSED AND THEY, AGAIN, COULD FIND NOTHING WRONG. THIS IS VERY FRUSTRATING AND STRESSFUL BECAUSE THE TRUCK IS FAIRLY NEW AND HAS BEEN WELL TAKEN CARE OF, BUT I CAN'T DEPEND ON IT TO START. I KNOW OTHER COLORADO OWNERS ARE HAVING THE SAME PROBLEM. I WOULD REALLY LIKE TO HAVE A SOLUTION. *TR

TRUCK SHUTS OFF WHILE DRIVING. PASS LOCK FAULTS OUT. I WAS TAKING A TURN THE OTHER DAY WHILE DRIVING 40 MILES PER HOUR WHEN MY TRUCK DIED. THIS IS THE THIRD TIME ITS HAPPENED. *TR

BRAKE LAMPS BLOW OUR REGULARLY EVERY WEEK OR TWO; BLOWER MOTOR QUITS INTERMITTENTLY DUE TO RUSTED CORRODED CONNECTOR; INSTRUMENT PANEL FAILS INTERMITTENTLY, NOTHING WORKS (GAUGES, LAMPS, ODOMETER) BUT ENGINE RUNS. BRAKE ISSUE HAS PERSISTED NOW FOR TWO YEARS. BLOWER STARTED IN EARLY 09 AND INSTRUMENT PANEL JUST STARTED OCT 09. *TR

BLOWER CONTROL FAILURE, INTERMITTENT. FAILURE OF THE CONTROLS IN THE FIRST THREE LEVELS AND AT TIMES ALL LEVELS OF THE CONTROL RESULTING FAILURE DOES NOT ALLOW THE WINDSHIELD TO DEFROST OR CLEAR IN INCLIMATE WEATHER. FULL FUNCTION MAY RETURN UPON RESTARTING THE ENGINE. *TR

WENT TO TURN ON THE CABIN FAN ON SPEEDS 1-3 AND THE FAN WOULD NOT TURN ON. SPEED 4 (THE FAN HAS 4 SPEEDS), THE FAN WOULD COME ON. AFTER GIVING THE TRUCK TIME TO WARM UP, SOMETIMES THE FAN WOULD THEN TURN RUN ON THE LOWER SPEEDS. THIS HAPPENED A MANY TIMES DURING THE SUMMER. SOMETIMES, EVEN GIVEN 20 MINUTES OF RUNNING THE VEHICLE, THE FAN WOULD NOT RUN ON LOWER SPEEDS. AFTER A MONTH OR SO WITHOUT DOING ANYTHING, THE FAN WORKED AS EXPECTED. LATELY THE PROBLEM STARTED TO REAPPEAR, AGAIN, THE FAN WOULD ONLY RUN ON HIGH. JUST LIKE BEFORE, EVEN GIVEN 20 MINUTES OF RUN TIME, THE FAN WOULD NOT RUN ON LOWER SPEEDS. THE FIX WAS TWO FOLD. THE ROOT CAUSE OF THE ISSUE WAS A BAD GROUNDING BLOCK, THAT THEN WOULD CAUSE A SHORT IN A WIRING HARNESS. THE GROUNDING CONNECTION FOR THE FAN, WAS SECURED. SECOND THE WIRING HARNESS FOR THE FAN CONTROL ALONG WITH A RESISTOR HAD TO BE REPLACED. PICTURES OF THE BURNED RESISTOR AND WIRING HARNESS CAN BE FOUND AT HTTP://WWW.FLICKR.COM/PHOTOS/IMRAMBI/SETS/72157622545918308/ . AS SHOWN, THERE IS BURNT PLASTIC WHERE THE WIRING HARNESS CONNECTS TO THE RESISTOR. THE RESISTOR IS INSIDE THE CABIN NEAR CARPET AND OTHER FLAMMABLES AND POSSES A FIRE HAZARD. *TR UPDATED 07/10/2012 *JS

I OWN A 2006 CHEVY COLORADO I HAD THE BRAKE LIGHT SWITCH REPLACE DUE TO RECALL ON MARCH 2006 THREE YEARS LATER THE SAME PROBLEM HAPPEN AGAIN THE BRAKE SWITCH WENT OUT. CHEVY CORP SAID SINCE THE REPAIR/RECALL WAS ALREADY PERFORMED I WOULD HAVE TO TAKE IT BACK TO THE DEALER SHIP TO GET IT LOOK AT AGAIN AND THE SAME PART THAT FAILED WAS GOING TO BE AN OUT OF POCKET EXPENSE. I DON'T THINK I OR ANYONE ELSE HAVING THE SAME PROBLEM SHOULD HAVE TO PAY FOR A DEFECTIVE PART. THIS POSES A SERIOUS PROBLEM BECAUSE IT CAUSED ME TO LOOSE MY BRAKE LIGHTS AND ALMOST GOT REAR ENDED FOUR TIMES. THIS POSES A VERY HIGH DANGER BECAUSE WHEN YOU ARE DRIVING YOU DO NOT EVEN KNOW WHEN YOU LOOSE YOUR BRAKE LIGHTS THERE IS NO INDICATIONS OR MESSAGES FROM THE DASH BOARD THAT YOUR LIGHTS ARE OUT. THIS IS JUST AN ACCIDENT WAITING TO HAPPEN HOPEFULLY THERE ARE NO DEATHS INVOLVED. THANK YOU FOR TAKING THE TIME TO READ THIS COMPLAINT. *TR

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

THE BACK LIGHTING OF THE INSTRUMENT PANEL JUST FAILED. NO INTERMITTENT FAILURE, ONE SECOND IT WAS WORKING THE NEXT IT DID NOT. ALL INSTRUMENTS WITHIN THE INSTRUMENT PANEL APPEAR TO STILL BE WORKING, BUT YOU CANNOT READ THE INSTRUMENT CLUSTER AT NIGHT, WHICH MAKES IT IMPOSSIBLE TO DETERMINE SPEED. THE DEALER CHECKED IT OUT AND DETERMINED THAT THIS FAILURE WAS COMMON IN THIS MODEL, AND THAT THE ENTIRE INSTRUMENT PANEL ($$$) HAS TO BE REPLACED (YOU CAN'T JUST REPLACE LIGHT BULBS). THIS IS A MANUFACTURING DEFECT THE DEALER REFUSES TO REPAIR UNDER WARRANTY. *TR

2006 CHEVROLET COLORADO - 4 DOOR - 5 CYLINDER ENGINE - 4 WHEEL DRIVE TRUCK HAS SHUT DOWN WHILE DRIVING IT WITH NO WARNING. THIS HAS HAPPENED 5-6 TIMES. DEALER CANNOT FIND PROBLEM AS IT IS ALWAYS RUNNING WHEN THEY GET IT. IT HAS BEEN TOWED TO THE DEALER ONCE. THIS PROBLEM IS EXTREMELY DANGEROUS AS THERE IS NO WARNING. THE ENGINE JUST QUITS. ONCE THE ENGINE QUITS AND YOU GET THE TRUCK OFF THE ROAD, YOU SIMPLY CUT THE KEY OFF AND RESTART THE TRUCK. ONE TIME I COULD NOT GET IT TO RUN AGAIN AND IT HAD TO BE TOWED. I CANNOT BEGIN TO TELL YOU HOW SCARY THIS IS WHEN YOU ARE IN TRAFFIC AND HAVE NO PLACE TO GO. THE DEALER TELLS ME TO KEEP DRIVING THE VEHICLE AS THE COMPUTER SHOWS NO PROBLEMS. *NM
