2016 Chevrolet Impala Electrical Problems

Your trunk floods when exposed to water from rain or car washes and doesn't drain properly, causing water damage to electrical components like your amplifier. You've reported sparks coming from the trunk area, which creates a potential fire hazard. The repair likely involves inspecting and sealing trunk drain holes or weatherstripping, plus checking for electrical damage in the trunk wiring and components.

Your car's blind spot detection system isn't working properly because of a problem with the Side Detection System Modules. Additionally, your car is having trouble starting and may require multiple attempts (sometimes 5, 10, 15 or more) before the engine turns over. These issues likely involve replacing or reprogramming the side detection modules and diagnosing the starting system.

Your car's radio and sound system turn on and off intermittently, sometimes going silent for days or weeks at a time. Since your vehicle uses this same system for audible safety warnings (like seat belt reminders, door ajar alerts, and low fuel warnings), you may not hear these important notifications when the sound is out. The problem started during normal highway driving about 2 months ago with no known cause. A technician will likely need to diagnose the radio/sound module and wiring to identify whether it's a faulty component, loose connection, or software issue.

Your car's lane departure warning system has a detection fault that prevents it from working properly. Chevrolet has acknowledged this is a known issue, but they've refused to repair your vehicle.

Your car's dashboard instruments suddenly stopped working, then came back on after restarting the vehicle a couple of times. Your lane departure warning system has stopped functioning since this happened. The problem doesn't occur consistently, and no warning lights appear—the systems just stop working and then restart.

Your dashboard displayed a message telling you to press the ignition button again to turn off the vehicle, happening randomly while driving or parked. The dealership replaced the ignition and other parts over five visits without fixing the issue, costing over $1,200. The actual problem turned out to be a damaged wire on the body control module that was grounding out on the car's frame. The fix will likely involve inspecting and repairing or replacing the damaged wire and its insulation on the body control module.

Electrical glitches and full loss of engine power wile driving. Dealer don’t know how to fix it. Very unsafe to drive

1. THE DISPLAY SCREEN WENT BLACK WHILE DRIVING USING NAVIGATION. THE FAULT WAS A DEFECTIVE HMI MODULE, GM PART # 84296482 AT A COST OF $1100 (SEE ATTACHED DOCUMENT). THE SUDDEN LOSS OF THE SCREEN WAS DISCONCERTING AND COULD HAVE CAUSED AN ACCIDENT. THIS SHOULD LEAD TO A RECALL AND REIMBURSEMENT OF THE REPAIR COST. 2. WHEN THE ADAPTIVE CRUISE CONTROL (ACC) CAUSES THE BRAKES TO BE APPLIED IT DOES SO VERY SUDDENLY AND IN THE ABS "CHATTERING" MODE EVEN WHEN THERE IS NO COLLISION DANGER. THIS PRODUCES A JOLT TO THE DRIVERS AND OCCUPANTS WHICH IS AN UNEXPECTED AND UNSAFE RESPONSE.

MY VEHICLE TURNED OFF SEVERAL DIFFERENT OCCASIONS ONCE AS I WAS DRIVING FREEWAY SPEED APPROXIMATELY 60-65MPH ENGINE COMPLETELY SHUT OFF I ATTEMPTED TO PUT IN NATURAL AND RE START THE IGNITION AS THE VEHICLE WAS STILL MOVING WITH NO POWER VEHICLE DID NOT START I MERGED TO THE SIDE OF THE HIGHWAY BREAKED TO STOP AND PLACED THE GEAR SHIFT ON PARK AND TRIED TURNING THE IGNITION ON AND STILL DID NOT TURN ON A FEW ATTEMPTS LATER CAR STARTED. ANOTHER INCIDENT I WAS DRIVING CAME TO A RED LIGHT AS I WAS WAITING FOR MY GREEN LIGHT MY CAR SHUT OFF WHILE I HAD MY FOOT ON THE BREAK I PUT THE SHIFT GEAR I TO PARK TURNED THE IGNITION ON AND CAR STARTED

TL* THE CONTACT OWNS A 2016 CHEVROLET IMPALA. THE CONTACT STATED THAT DURING INCLEMENT WEATHER, WATER ENTERED THE VEHICLE FROM THE REAR TAILLIGHTS. THE CONTACT STATED THAT THE TRUNK AND THE INSIDE CABIN OF THE VEHICLE EXPERIENCED WATER INTRUSION IN THE VEHICLE. THE CONTACT STATED THAT THERE WAS MOLD AND AN ABNORMAL ODOR INSIDE OF THE VEHICLE. THE VEHICLE WAS TAKEN TO TWO INDEPENDENT MECHANICS TO BE DIAGNOSED. IT WAS CONFIRMED THAT THE FAILURE WAS WITH THE DRIVER'S AND PASSENGER'S SIDE TAILLIGHTS. THE CONTACT STATED THAT THE COMPUTER IN THE TRUNK OF THE VEHICLE WAS COMPLETELY UNDER WATER. ADDITIONALLY, THE SPARE TIRE AND JACK WERE RUSTED. THE VEHICLE WAS TAKEN TO MIKE ANDERSON CHEVROLET (5333 W IRVING PARK RD, CHICAGO, IL 60641, 773-465-2000) AND AN APPOINTMENT WAS SCHEDULED TO HAVE THE VEHICLE INSPECTED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND INFORMED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 32,000.

SIDE DETECTION SYSTEM HAS FAILED, CAUSING MY DASH BOARD TO STAY OFF OR FLICKER AND AT TIMES MY VEHICLE NOT STARTING.

CAR WAS GOING 80 MPH (CRUISE CONTROL) ON THE HIGHWAY, AND IT GLITCHED TURNED ON AND OFF. WE WERE GOING DOWN HILL MOTION CAR SLOWED DOWN BUT CONTINUED ROLLING. WHEN THE CAR GLITCHES BACK ON 1 MINS LATER KICKED BACK ON CAR PICKED BACK UP TO THE 80 MPH ON THE CRUISE CONTROL. *TR

CONCERNING THE 2016 CHEVROLET IMPALA TRUNK, THERE WERE SEVERAL OCCASIONS OF THE TRUNK BEING FOUND OPENED ON IT'S OWN WHEN NOT IN USE. RECENTLY, THE TRUNK WILL NOT CLOSE OR WILL NOT OPEN. I'VE PURCHASED FUSES TO NO AVAIL AS THEY CONTINUE TO BLOW. CONTACTED CHEVROLET CUSTOMER CARE, THEY LIED AND SAID NO COMPLAINTS HAD BEEN RECEIVED ON ANY MODELS SINCE 2000. THERE ARE AT LEAST 2 OTHER COMPLAINTS ABOUT THE TRUNK ON THE NTHSA SITE. CHEVROLET (ROB) INFORMED ME MY COMPLAINT IS NOW IN THEIR RECORDS. CONCERNING THE ELECTRICAL SYSTEM, DOORS COULD BE HEARD CLICKING WHEN NOT IN USE. MY BATTERY HAS DRAINED SEVERAL TIMES DUE TO EROSION. I PURCHASED NEW CABLE WHICH WORKED FINE FOR SOME MONTHS BUT THEN HAD TO PURCHASE NEW BATTERY. THESE ARE OBVIOUS ISSUES GM SHOULD ADDRESS.

WHEN DRIVING THE VEHICLE EVERYTHING GOES OUT YOU HAVE NO CONTROL, THE VEHICLE IS COMPLETELY DARK, ABSOLUTELY NO CONTROL. THE VEHICLE WAS IN MOTION, HAD NO POWER AT ALL

WENT TO START THE CAR AND THE SIDE DETECTION SYSTEM WENT OUT AND IS CAUSING ELECTRICAL PROBLEMS IN THE CAR. SIDE DETACTION, COMPUTER, IGNITION, ETC.

CAR WOULD NOT START AND ALL OF MY SENSORS ARE GOING OFF NEEDING TO BE SERVICED. THEN IT GOES AWAY. I DROVE IT THE DAY BEFORE WITH NO PROBLEMS. GO TO MY CAR THE NEXT DAY AND ALL OF MY SENSORS ARE ACTING UP.

SIDE DETECTION MODULE IS FAILING. I RESEARCHED AFTER MY DASHBOARD WON'T TURN ON, AND AFTER READING SIMILAR COMPLAINTS FROM OTHER IMPALA OWNERS, IT IS DUE TO THE SIDE DETECTION MODULES NOT WORKING PROPERLY. APPARENTLY WHEN THE MODULES FAIL THEY CAN CAUSE ALOT OF ELECTRICAL DAMAGE TO THE VEHICLE. CHEVY OR GM IS NOT ANSWERING MY QUESTIONS, AND I DONT SEE THE NEED TO PAY OUT OF POCKET FOR SOMETHING THAT SEEMS TO BE A PROBLEM IN MOST PEOPLE'S IMPALA.

THE WIRING USED IS TASTY TO SQUIRRELS AND MY RIGHT HAND BLINKER WIRING HAS BEEN CHEWED UP TWICE NOW, FIXING IT HAS COST $1000.00 EACH TIME. VEHICLE WAS STATIONARY PARKED IN MY DRIVEWAY AT HOME.

TL* THE CONTACT OWNS A 2016 CHEVROLET IMPALA. WHILE STOPPED AT A TRAFFIC LIGHT, THE VEHICLE STALLED. THE CONTACT WAS ABLE TO RESTART THE VEHICLE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. AN APPOINTMENT WAS MADE TO HAVE THE VEHICLE DIAGNOSED AT FREEDOM CHEVROLET BUICK GMC (8008 MARVIN D LOVE FWY, DALLAS, TX 75237, (972) 649-0829). THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 57,292. THE VIN WAS NOT AVAILABLE.

ON APRIL 2ND, 2018, I WAS DRIVING TO WORK AROUND 4:50 A.M. DRIVING ON THE 303SB ONLY ABOUT 7 MINUTES INTO MY DRIVE I NOTICED THAT MY VEHICLE BEGAN TO LAG AND STALL OUT, I BEGAN TO NOTICE GREY SMOKE COMING FROM THE HOOD AND THAT'S WHEN I REALIZED THAT MY CAR WAS ON FIRE. WHILE TRYING TO AVOID TRAFFIC AND AFTER ALMOST BEING HIT BY ONCOMING TRAFFIC I WAS FINALLY ABLE TO GET MY VEHICLE INTO A SAFE ARE ON THE SIDE OF THE ROAD AND CALL EMERGENCY ROADSIDE ASSISTANCE ON PROVIDED BY MY AUTO INSURANCE USAA. MY CONCERN IS THAT THE VEHICLE NEVER PROVIDED ANY TYPE OF NOTIFICATION LETTING ME KNOW THAT THE VEHICLE WAS SEVERELY DAMAGED. IF MY OIL IS LOW MY VEHICLE TELLS ME SOMETHING, WHEN THE TIRES ARE LOW ON AIR, MY VEHICLE TELLS ME. HOW COME WHEN MY VEHICLE CAUGHT FIRE AND WHILE IT BEGAN STALLING OUT I STILL RECEIVED NO NOTICE? I COULD HAVE BEEN KILLED HAD I GOT HIT BY ONCOMING TRAFFIC AND THE SITUATION MAY HAVE ENDED A LOT WORSE. I HAD MY VEHICLE TOWED TO THE NEAREST REPAIR SHOP AS COVERED UNDER THE USAA ROADSIDE ASSISTANCE ENDORSEMENT THAT BEING CHEVROLET SANDS. I RECEIVED A CALL FROM A REP WHO STATED THAT THE VEHICLE HAD HAD PRE-EXISTING DAMAGE TO THE VEHICLE SUCH AS OLD BATTERY ACID THAT HAD OVER TIME ATE AT THE WIRING OF THE VEHICLE CAUSING THE TRANSMISSION TO BLOW OUT. THIS VEHICLE IS A DEATH TRAP. I MENTIONED THAT THE VEHICLE WAS A CERTIFIED PRE-OWNED VEHICLE AND THAT THE VEHICLE WAS ONLY IN OUR CARE FOR LESS THAN A YEAR IN A HALF AND THAT WHEN WE BOUGHT THE VEHICLE IT CONTAINED 20,022 MILES AND THAT THE VEHICLE NOW ONLY HAD ABOUT 65,000 MILES. NONE OF THE SECURITY FEATURES EVER TURNED ON THE AUTO STOP FUNCTION DOESN'T OPERATE, THE BATTERY WAS BUILT ON TOP OF THE TRANSMISSION SAFETY ISSUE. THE IGNITION CUT OFF DEVICE DIDN'T WORK.

TAKATA INFLATORS, MY AIR BAG PAT KEEPS COMING ON AND I HAVE TAKEN IT TO THE DEALERSHIP TO GET IT CHECK AND IT CONTINUES TO COME ON.

ITS WAS ROUND 9:00 P.M. WHEN I WAS DRIVING DOWN A TWO LANE ROAD, GOING AROUND A CURVE WHEN ALL MY INTERIOR LIGHTS(DASH BOARD, RADIO, AND GEAR SHIFT LIGHTS)TURN OFF FOR ABOUT THREE SECONDS. THE CAR FELT AS IT WAS COMPLETELY OFF BUT POWERED BACK UP AND CONTINUED TO DRIVE NORMAL.

FOR THE PAST 3 MO. UPON STARTING THE VEHICLE I HEAR A "POP" NOISE. IT ONLY HAPPENS EVERY ONCE IN A WHILE IN THE MORNING OR THE EVENING WHEN I GET OFF WORK. SOMETIMES IT WILL GO A WEEK OR MORE WITHOUT MAKING THE SOUND. THE SOUND WILL NOT REPEAT ITSELF IF I IMMEDIATELY TURN THE CAR OFF AND RESTART IT. THE 1ST TIME I TOOK IT TO THE DEALERSHIP, THEY SIAD NOTHING WAS WRONG & THEY DIDN'T HEAR THE "POP". THE 2ND TIME THEY SAID IT WAS THE EXHAUST SO THEY REPALCED SOME HOSES, THE 3RD TIME, IN WHICH THE "POP" WAS MORE FREQUENT AND LOUDER, THEY SAID IT WAS THE STARTER STICKING. AFTER REPLACING THE STARTER, A WEEK LATER, I STILL HEAR THE "POP" UPON STARTING IT. THE VEHICLE IS NOT IN MOTION WHEN THIS HAPPENS. OBVIOUSLY, THEY DON'T KNOW WHAT THE PROBLEM IS IF THEY DIAGNOSED IT AS THE EXHAUST FIRST & THEN THE STARTER AND IT'S STILL MAKING THE SAME NOISE AFTER SERVICING BOTH SAID PROBLEMS. I AM VERY FRIGHTENED ABOUT THIS PROBLEM BECAUSE 7 MO. AGO MY BUICK PARK AVE CAUGHT FIRE ON ME IN MY GARAGE UPON STARTING IT AND HEARING THE SAME "POP" NOISE. A COWORKER OF MINE HAS THE SAME KIND OF CAR AND IS EXPERIENCING THE SAME PROBLEM. I AM ALMOST SURE WE AREN'T THE ONLY TWO CONSUMERS WHO IS EXPERIENCING THIS ISSUE. I PURCHASED THE CARM ON 04/07/2017 AND THIS PROBLEM STARTED ABOUT THE 1ST TO 2ND WEEK IN AUGUST AFTER MY 1ST OIL CHANGE. PLEASE LOOK INTO THIS, TOO MANY CARS ARE CATCHING FIRE AND PEOPLE ARE BEING HURT AND EVEN KILLED.

VEHICLE SOMETIMES DOESN'T WANT TO STAR(YOU TURN THE KEY TO START AND IT DOES NOTHING ) ALSO WHEN CAR GOES ON AUTO STOP AND COMES OFF AUTO STOP IT CLUNKS LIKE IF THE CAR HAD BAD MOTOR MOUNTS

WHEN TRAVELING ON THE HIGHWAY OR LOCAL ROADS. MY VEHICLE WOULD WARN ME TO SHIFT INTO PARK TO STOP THE ENGINE. THE AFTER 3 NOTICES IT WOULD SHUTDOWN COMPLETELY.
