2007 Chevrolet Impala Engine Problems

Your car's engine is reducing power, and a diagnostic code P2138 has been triggered. This typically indicates an issue with the throttle pedal or electronic throttle control system that's preventing your engine from operating at full power. The repair will likely involve inspecting or replacing the throttle pedal sensor or electronic throttle body components.

Your car's coolant crossover pipe gaskets have rotted away, causing the heating system to stop working. This left your family without heat during winter driving. Fixing this will likely involve replacing the damaged gaskets and possibly the crossover pipe itself.

While driving at 25 mph and approaching a stop sign, your car suddenly started shaking badly and displayed an "engine losing power" warning code. You were able to pull over safely, but the incident was frightening. The previous owner reported experiencing the same problem about 6 months earlier. The issue may involve a failing sensor, ignition component, or fuel delivery problem that needs diagnostic testing to identify the root cause.

I JUST RECENTLY HAD THE ENGINE POWER REDUCED NOTIFICATION COME UP ON MY CAR AND POWER REDUCED A GOOD AMOUNT. I GOT HOME AS SOON AS I COULD AND TURNED THE VEHICLE OFF. DIDN'T COME ON THE NEXT DAY BUT WHILE DRIVING IN TOWN, 25-45 MPH, I COULD FEEL A LITTLE OF A PULL TIME TO TIME, SAW THAT THE RPM NEEDLE WOULD JUMP TIME TO TIME. I HAVE ALSO DRIVEN IT ON THE INTERSTATE AND IT IS JUST THE SAME THING.

WHILE STARTING MY CAR THE VEHICLE BEGAN SHAKING AND THE ENGINE LIGHT CAME ON. THERE WAS ALSO A MESSAGE STATING ENGINE REDUCED POWER. THIS IS NOT THE FIRST TIME I HAD THIS HAPPEN.

I HAD THAT REPLACED ON TO TURN AROUND AND HAVE THE SAME PROBLEM TWO DAYS LATER. I RECENTLY SEARCHED THIS ISSUE ONLINE AND NOTICED I'M NOT THE ONLY PERSON WITH THIS ISSUE. I CALLED GM AND THE REPRESENTATIVE INFORMED ME THAT UNFORTUNATELY THERE WASN'T A RECALL ON THIS ISSUE. THIS IS VERY UNSAFE AND I'M AFRAID TO DRIVE THIS CAR. I TRAVEL A LOT ON THE FREEWAY AND I WOULD HATE FOR THE CAR TO STOP WHILE DRIVING WITH MYSELF AND CHILDREN INSIDE. THIS VEHICLE COMPLAINT REALLY NEEDS TO BE ADDRESSED BEFORE SOMEONE GETS KILLED.

I WAS DRIVING AT 20 MPH SLOWING TO TURN INTO MY PARKING LOT AT WORK AND SUDDENLY THE CAR JOLTED AND THE POWER DECREASED TO MAYBE HALF. THE CAR NEVER COMPLETELY SHUT OFF. I WAS ABLE TO COAST INTO A PARKING SPOT AT WORK WHEN I TRIED TO ACCELERATE THERE WAS NO POWER LEFT AT ALL. ALL I COULD DO WAS COAST, THE CAR STILL NEVER COMPLETELY SHUT OFF. THIS WAS EXTREMELY SCAREY, I JUST THANK GOD MY 5 YEAR OLD DAUGHTER WAS NOT WITH ME AT THE TIME!!

I PURCHASED MY VEHICLE IN LATE MARCH 2010. SHORTLY THEREAFTER, MY CAR BEGAN TO LOSE POWER. I HAD AT LEAST 3 INCIDENCES THAT I CAN REMEMBER, 1 OF WHICH WAS GOING DOWN THE INTERSTATE AND THE CAR COMPLETELY DIED. FRIGHTENED, I WAS ABLE TO GET THE CAR TO THE SHOULDER AND PUT THE VEHICLE IN PARK. MY FIRST REACTION WAS TO ATTEMPT TO RESTART THE VEHICLE. IT STARTED UP RIGHT AWAY AND I WAS ABLE TO MAKE IT SAFELY HOME. THE OTHER INCIDENTS WERE ON MAIN ROADS IN TOWN. THE CAR DID THE SAME THING. AFTER THE INTERSTATE ORDEAL, I IMMEDIATELY TOOK THE CAR TO BEATY CHEVROLET IN KNOXVILLE, TN. THEY STATED THAT THE IGNITION WENT OUT AND NEEDED TO BE REPLACED. NOW, I UNDERSTAND THAT OTHER GM OWNERS HAVE HAD THIS SAME ISSUE. A RECALL DEFINITELY NEEDS TO BE ISSUED SO NO MORE PEOPLE ARE PUT IN HARM'S WAY. THIS IS A KNOWN ISSUE ACCORDING TO AN OPERATOR NAMED [XXX] AT GM WHEN I CALLED A FEW MINUTES AGO TO INQUIRE ABOUT THE CURRENT RECALL REGARDING THE KEY/FOB TURNING ISSUE. SHE STATED THAT THE RECALL HAD NOT YET BEEN ISSUED REGARDING MY ISSUE AND THAT I NEEDED TO FILE A COMPLAINT WITH YOUR DEPARTMENT. I BELIEVE THAT THIS KNOWN ISSUE IS BEING SWEPT UNDER THE RUG BY THE BIG CORPORATION AND NEEDS TO BE DEALT WITH IMMEDIATELY. I DESERVE A FULL REFUND FOR "FAULTY" MANUFACTURED PARTS. LUCKILY, MY FAMILY NOR I WERE INJURED DURING THE LISTED INCIDENTS LISTED ABOVE. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

2007 CHEVY IMPALA WILL HAVE THE ENGINE SHUT DOWN. THE WARNING "ENGINE POWER REDUCED" "SERVICE TRACTION CONTROL" WILL COME ON, ALONG WITH THE CHECK ENGINE LIGHT. YOU CANNOT ACCELERATE, THE CAR SHAKES, AND IS DIFFICULT TO DRIVE. HAD THE GAS PEDAL AND THE EQUIVALENT PART IN THE ENGINE REPLACED (AT DIFFERENT TIMES) AND HAD THE CODES COME UP IN BETWEEN THE PARTS BEING REPLACED AND STILL NOW. TOOK IT INTO A CHEVY DEALER AND IT DOESN'T ACT UP FOR THEM. AND FOR WHATEVER REASON THEIR COMPUTER DOESN'T SHOW ANY PROBLEMS. THERE ARE MANY COMPLAINTS ABOUT THIS ON DIFFERENT WEBSITES. I CALLED GM AND HAVE A CASE OPENED TO GET HELP FROM THEM. IT'S EXTREMELY SCARY TO HAVE THE ENGINE POWER REDUCED WHILE DRIVING AND IT'S VERY DANGEROUS BECAUSE YOU CAN'T MANEUVER OR ACCELERATE. *TR

WIFE WAS DRIVING HOME AND THE ENGINE POWER WAS REDUCED AND SERVICE TRACTION CONTROL CAME UP ON THE DASH DISPLAY. POWER WAS CUT, LEFT HER DRIVING AT AROUND 40MPH I DROVE IT TODAY, JULY 1,2014, IT DID FINE FOR ABOUT THE FIRST MILE THEN SERVICE TRACTION CONTROL, REDUCED ENGINE POWER DISPLAY CAME ON AGAIN. I DROVE IT 4 TIMES TODAY, SEEMS THAT IF THE CAR SIT FOR A FEW HOURS, IT RAN FINE, FULL POWER, NO ISSUES FOR ABOUT THE FIRST MILE TO MILE AND A HALF THEN IT WOULD COME UP WITH THE SERVICE TCS AND REDUCED ENGINE POWER WHICH LEAVES YOU AT VERY REDUCED SPEEDS. LUCKILY I LIVE IN THE COUNTRY SO TRAFFIC WASN'T A HUGE ISSUE. I RESEARCHED ONLINE AND THIS SEEMS TO BE A COMMON OCCURANCE WITH MANY YR MODEL IMPALAS SO I WANTED TO REPORT MINE SO IT WOULD BE ON RECORD AS WELL. 2007 IMPALA LT2 WITH 3.9L ENGINE. THANKS. *TR

ONCE AGAIN THE SERVICE TRACTION CONTROL AND ENGINE POWER REDUCED LIGHTS ARE ON. WE HAVE TAKEN THE CAR TO DON BROWN CHEVY DEALERSHIP MULTIPLE TIMES WITH NO FIX IN SIGHT. BEEN TOLD IT'S A CLIP THAT CAME LOOSE AND WAS FIXED MULTIPLE TIMES. IT WOULD BE HELPFUL TO FIND SOME PLACE THAT CAN ACTUALLY FIX THE PROBLEM OR FOR GM TO COME UP WITH A FIX. THIS IS NOT A RECALL ITEM AND SHOULD BE ON THE LIST DUE TO THE MULTIPLE INCIDENTS. THIS PROBLEM HAS BEEN OCCURRING INTERMITTENTLY ON THE CAR SINCE 2009. *TR

WHILE DRIVING MY 07' CHEVY IMPALA THE TEMPERATURE GAUGE ARM OFTEN WILL DROP TO 'C' AS IF THE ENGINE TEMPERATURE IS COLD, THEN THE DRIVERS INFORMATION DISPLAY PANEL WILL DISPLAY A MESSAGE "ENGINE HOT TURN OFF A/C". I'VE HAD THE THERMOSTAT REPLACED, RADIATOR COOLANT DRAINED AND REPLACED, HOPING TO FIX THIS PROBLEM, BUT I'M STILL DEALING WITH IT. AFTER DOING SOME RESEARCH I'M FINDING THAT THERE HAS BEEN OTHER CHEVY VEHICLE OWNERS DEALING WITH THIS SAME ISSUE, WHICH IS MOST LIKELY A BAD 'ENGINE COOLANT TEMPERATURE SENSOR (ECT). *TR

I WAS DRIVING TO WORK AND A MESSAGE POPPED-UP "REDUCED ENGINE POWER" MY SPEED WAS QUICKLY REDUCED FROM 45 MPH TO 20 MPH. I IMMEDIATELY PULLED OVER LUCKILY I WAS NOT HIT BY ANOTHER VEHICLE. THE CHECK ENGINE LIGHT REMAINS ON IN THE VEHICLE. I HAD THE VEHICLE DIAGNOSED AND WAS TOLD THE THROTTLE SENSOR NEED TO BE REPLACED. THIS IS A DANGEROUS ISSUE THAT GM NEED TO ADDRESS. NUMEROUS OF IMPALA OWNERS HAVE FILED COMPLAINTS, BUT HAVE BEEN IGNORED. I FEEL AS THOUGH GM SHOULD RECALL THE VEHICLES AND FIX THE DEFECTS... THIS IS PUTTING ME, MY CHILDREN, AND MANY OTHERS AT RISK.

INTERMITTENT PROBLEMS WITH "SERVICE TRACTION CONTROL" AND "ENGINE POWER REDUCED". MY IMPALA IS STARTING TO RUMBLE AND JOSTLE WHEN THESE WARNINGS APPEAR. HOWEVER, I CAN'T FIGURE OUT THE REASON. *TR

WHILE I WAS DRIVING AN ERROR MESSAGE APPEARED ON THE PANEL "ENGINE POWER REDUCED". THE CAR IMMEDIATELY SLOWED DOWN AS IF THE ENGINE HAD CUT-OFF COMPLETELY. IT DID NOT AND I WAS ABLE TO DRIVE TO THE SIDE OF THE ROAD AT ABOUT 10 MPH. LUCKILY IT WAS LATE AT NIGHT, THE FEW CARS THAT WERE DRIVING NEAR ME WERE ABLE TO CHANGE LANES BEFORE A COLLISION OCCURRED. *TR

I AM THE OWNER OF A 2007 CHEVY IMPALA, WHICH IS NO LONGER UNDER WARRANTY. (LAST 8 OF VIN #[XXX]) I HAVE HAD SEVERAL PROBLEMS WITH MY VEHICLE FOR THE PAST SEVERAL YEARS STARTING WITH THE "CHECK ENGINE LIGHT." WHEN I WAS IN SCHOOL IN VIRGINIA THE LIGHT FIRST CAME ON AND I TOOK IT TO A GM DEALER IN VIRGINIA FOR A WEEK, THEY SAID THEY FIXED IT AND A WEEK LATER IT CAME BACK ON. I BROUGHT THE VEHICLE BACK AND THEY SAID THEY FIXED IT AGAIN, HOWEVER IT ONCE AGAIN CAME BACK ON. THIS IS EXTREMELY FRUSTRATING BECAUSE IT WOULDN'T LET ME ACCELERATE OVER 25 MPH AND I NEEDED TO GET HOME TO NEW YORK. SEVERAL MONTHS LATER I RECEIVED THE "CHECK ENGINE LIGHT" AGAIN AND BROUGHT IT TO A GM DEALER IN NEW YORK, WHO SUPPOSEDLY FIXED THIS PROBLEM. LAST WEEK THE "CHECK ENGINE" LIGHT CAME ON AGAIN WITH THE MESSAGE "REDUCED ENGINE POWER" ONCE AGAIN AND THE CAR STOPPED ON THE HIGHWAY AND SHUT-OFF. THIS IS EXTREMELY DANGEROUS AS I WAS STOPPED ON A 60MPH HIGHWAY WITH CARS JUST MISSING ME. I HAVE SPENT THOUSANDS OF DOLLARS AS A COLLEGE STUDENT TRYING TO REPAIR THIS ISSUE WHICH STILL HAS NOT BEEN RESOLVED AND NOW HAS BECOME AN INCONVENIENCE, A TOLL ON MY BANK ACCOUNT, AS WELL AS A VERY DANGEROUS SAFETY ISSUE. I AM SCARED TO DRIVE MY CAR TO WORK EVERYDAY NOW, WHICH SHOULD NOT BE THE PROBLEM BECAUSE THE ENGINE LIGHT AND REDUCED POWER IS STILL ON. I HAVE LOOKED ONLINE AT SEVERAL MESSAGE BOARDS AND EVERYONE HAS SAID THE SAME THING ABOUT THIS PROBLEM. CLEARLY THIS IS A MANUFACTURING ERROR AND AS A SAFETY MEASURE GM SHOULD REALLY PLACE A RECALL ON THIS BEFORE SOMEONE DIES OR IS SERIOUSLY INJURED FROM THIS. I APPRECIATE YOUR IMMEDIATE RESPONSE TO THIS INCONVENIENCE AND SAFETY ISSUE. THANK YOU, INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

WHILE DRIVING ON THE INTERSTATE, A MESSAGE WAS DISPLAYED SAYING "SERVICE TRACTION CONTROL" AND "REDUCED ENGINE POWER". I WAS USING CRUISE CONTROL AND IT SHUT OFF AFTER THE MESSAGES WERE DISPLAYED AND I WAS UNABLE TO STAY AT THE SPEED LIMIT OR ACCELERATE QUICKLY IF NEEDED. IN ANOTHER INCIDENT, I WAS DRIVING AND THE TWO MESSAGES DISPLAYED AND A FEW MINUTES LATER THE ENGINE SHUT OFF COMPLETELY. THE POWER STEERING WAS NOT WORKING AND THE ENGINE WAS NOT RESPONDING. THE ONLY WAY TO GET THE CAR RUNNING AGAIN WAS TO SHUT IT OFF AND WAIT SEVERAL MINUTES UNTIL IT WOULD START AGAIN. *KB

MY VEHICLE HAS THE 3.9 L LTZ PACKAGE. IT USES 2 TO 3 QUARTS OF OIL PER OIL CHANGE. I AM CURRENTLY WORKING WITH THE DEALERSHIP TO MONITOR MY OIL CONSUMPTION EVERY 1,000 MILES. SO FAR WE HAVE USED 1/2 QUART IN 2,000 MILES. THE DEALERSHIP DOES NOT SEEMED CONCERNED BUT FRANKLY MY CAR SHOULD NOT BE USING ANY OIL. GM SHOULD DO SOMETHING. WE HAVE A 10 YEAR/100,000 MILE WARRANTY. I HOPE GM DOESN'T TRY TO SQUEAK OUT OF FIXING THIS ISSUE. *KB

VEHICLE'S TRANSMISSION SLIPS WHEN ACCELERATING, AND ALSO JERKS WHEN IDLING. THIS IS A COMMON ISSUE THAT HAS BEEN REPORTED IN MULTIPLE PLACES BY A LARGE NUMBER OF PEOPLE. ISSUE HAS BEEN INCREASING IN FREQUENCY - MAKING THIS CAR UNSAFE TO DRIVE, YET CHEVROLET HAS NOT BOTHERED TO ADDRESS THE NOW OBVIOUS PROBLEM. *TR

I HAD NUMEROUS PROBLEMS WITH THIS VEHICLE (ALMOST THROUGH MY THIRD SET OF TIRES, OXYGEN SENSOR GOING AT 46,000 MILES, RUST BEGINNING AT 38,000 MILES {CAR WAS TWO YEARS OLD}, AND THE BATTERY GOING PREMATURELY). LAST WEEK, I ATTEMPTED TO PUT ON MY REAR DEFOGGER. THE LIGHT CAME ON, BUT MY REAR WINDSHIELD WAS STILL FOGGED UP. THE DEFROSTER ALSO DOES NOT BLOW COLD AIR IF THE CAR IS IN PARK. *TR

I OWE A CHEVY IMPALA 2007 AND I WAS HAVING TROUBLE WITH THE CAR MUFFLER, IT WAS MAKING A NOISE. ON TAKING IT TO THE SERVICE SHOP, I WAS TOLD THAT IT NEEDED TO BE CHANGED AND THE PROBABLE REASON IS THE SALT HAS CAUSED THE DAMAGE. THE CAR HAS RUN 69 K MILES. I ENDED UP CHANGING THE MUFFLER. *KB

TL*THE CONTACT OWNS A 2007 CHEVROLET IMPALA. THE CONTACT STATED THAT THE ALL FOUR TIRES WERE WORN DOWN TO THE METAL AFTER A SHORT PERIOD OF TIME. THE TIRES WERE REPLACED. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO STATED THAT THEY WERE UNAWARE OF THE PROBLEM. A LOCAL MECHANIC STATED THAT THE WHEELS WERE THE CAUSE OF THE TIRE WEAR. THE CONTACT CALLED THE MANUFACTURER WHO STATED THAT THEY WOULD LOOK INTO THE PROBLEM. ADDITIONALLY, THERE WAS CORROSION ON THE EMISSIONS SOLENOID WHICH SHE WAS ALERTED TO WHEN THE CHECK ENGINE LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO THE DEALER WHO STATED THAT EITHER CARBON WAS STUCK IN THE VALVE OR THE SOLENOID WAS FULL OF WATER. THE VEHICLE WAS REPAIRED. ALSO, THE CABLE TO THE BATTERY WAS CORRODED. TWO MECHANICS INSPECTED THE VEHICLE AND STATED THAT THE FAILURE WAS NOT CAUSED BY NORMAL WEAR AND TEAR. THE VEHICLE WAS REPAIRED. THE CURRENT MILEAGE WAS APPROXIMATELY 73,000. THE FAILURE MILEAGE WAS APPROXIMATELY 66,000.

I PURCHASED A USED 2007 CHEVROLET IMPALA 3.5L LS WITH APPROXIMATELY 25K MILES IN OCTOBER 2009. BETWEEN OIL CHANGES MY CAR HAS BEEN BURNING OUT OIL 2-3 QUARTS BETWEEN OIL CHANGES). I HAVE TAKEN IT BACK TO THE DEALERSHIP 3 TIMES TO HAVE THIS ISSUES CORRECTED. THEY THOUGHT IT WAS A CLOGGED SENSOR AND CHANGED IT BECAUSE THEY COULD NOT FIND ANY LEAKS. THEY CHANGED THE SENSOR BUT THE VEHICLE IS STILL BURNING BETWEEN 2 - 3 QUARTS. I HAVE MY OIL CHANGED EVERY 3K MILES. THE OIL LIGHT DOES COME ON TO ALERT ME WHEN I AM LOW. I AM AFRAID THAT THE ENGINE IS GOING TO SEIZE UP. I WANT TO BRING IT BACK TO THE DEALER AGAIN BUT THE LAST 3 TIME I HAVE TAKEN IT THERE THEY HAVE BEEN UNSUCCESSFUL IN FINDING THE PROBLEM. I HAVE BEEN A GM CUSTOMER WITH THIS DEALERSHIP FOR APPROXIMATELY 17 YRS AND HAVE NEVER HAD A PROBLEM WITH ANY OF MY OTHER GM PRODUCTS AND THE DEALERSHIP HAS ALWAYS BEEN VERY HELPFUL. *TR

BOUGHT 2007 IMPALA YEAR AGO LATELY GETTING A SMELL OF ANTIFREEZE AROUND PASS SIDE FRT CHECK FOR LEAKS NOTHING FOUND NOT DOWN ON COOLANT AND GETTING HEAT ANY SUGGESTIONS ON THIS. *TR

WE BOUGHT OUR 2007 CHEVROLET IMPALA 3LT NEW IN FEBRUARY 2007. THE CAR JUST TURNED OVER 50,000 MILES. AT 38,000, WE NOTICED THE PASSENGER SEAT HEATING ELEMENT QUIT WORKING. CHEVY DEALER ESTIMATES THE COST OF REPAIRS AT ABOUT $200. AT 48,000 THE SHIFTER RELEASE SWITCH STOPPED WORKING, SO THE SHIFTER COULD NOT BE MOVED FROM THE PARK POSITION. CHEVY DEALER SAID A WIRE BROKE IN THE CENTER CONSOLE AND REPAIRS WERE $137. FROM ABOUT 45,000 MILES TO PRESENT, THE TRANSMISSION OCCASIONALLY SLIPS WHEN ACCELERATING FROM A STOP AT AN INTERSECTION. THE ENGINE REVS FOR ABOUT A SECOND OR TWO BEFORE THE TRANSMISSION ENGAGES. THE CHEVY DEALER HAS HAD THE CAR IN TWICE FOR THIS PROBLEM, THE SECOND TIME FOR MORE THAN A WEEK, AND WE'RE TOLD IT DOESN'T HAPPEN IN THE SHOP. THE SLIP HAPPENS ABOUT ONCE EVERY TWO DAYS THAT WE NOTICE. NOW, AT 50,100 MILES, THE EXHAUST HAS GOTTEN LOUDER AND A REPAIR SHOP SAID THERE'S A CRACK ON THE TOP OF THE LEFT MUFFLER. THE CHEVY DEALER SAYS IT'S NOT IN WARRANTY, AND THE JOB WILL COST $1,152. AN INDEPENDENT REPAIR SHOP SAYS THE MUFFLER CAN BE REPLACED FOR $160. *TR

I HAVE A 2007 CHEVY IMPALA LT I BOUGHT IT USED WITH 30,000 MILES ON IT. IN BETWEEN OIL CHANGES THE OIL WARNING COMES ON TELLING ME TO ADD MORE OIL. I'VE TAKEN IT TO THE DEALERSHIP AND TO OTHER MECHANICS AND CANNOT FIGURE OUT WHAT IS WRONG. THEY HAVE CHECKED FOR LEAKS AND THERE ARE NONE. THEY SAID MAYBE THE ENGINE IS BURNING IT OFF BUT THEY DON'T SMELL IT. NOBODY CAN TELL ME WHAT IS WRONG, SO IN BETWEEN OIL CHANGES I HAVE TO PUT 1-2 QUARTS OF OIL IN IT. I CHANGE MY OIL EVERY 6,000 MILES. *TR

2007 CHEVROLET IMPALA HAS STRONG ODOR (SKUNK-LIKE SMELL) THAT RADIATES FROM THE VEHICLE'S INTERIOR WHEN THE OUTSIDE CLIMATE BEGINS TO WARM UP. GM ISSUED A TSB (#08-08-110-019) FOR THE PROBLEM, BUT WILL NOT REPAIR VEHICLES THAT ARE OUT OF WARRANTY. THE PROBLEM PERTAINS TO INCORRECT PARTS (A RUBBER BRAKE BOOSTER BOOT AND INSTRUMENT PANEL INSULATOR PAD) INSTALLED IN VEHICLES BETWEEN JANUARY 1 2007 AND MARCH 1 2007 THAT EMIT THIS ODOR. THE SMELL IS SO SEVERE AT TIMES THAT IT CAUSES SEVERE HEADACHES AND NAUSEA TO THE VEHICLES OCCUPANTS. ON SEVERAL OCCASIONS, THE CAR HAD TO BE STOPPED AND ALL OCCUPANTS EXIT WHILE THE CAR "AIRED-OUT". SURELY, STRONG CHEMICALS ARE BEING DISBURSED IN A SMALL SPACE THAT IS MAKING PEOPLE SICK AND GM NEEDS TO ADDRESS THIS ISSUE. *TR
