2012 CHEVROLET VOLT Complaints

TEMPERATURE SENSORS RESPONSIBLE FOR MONITORING THE BATTERY PACK FAIL UNEXPECTEDLY. SOMETIMES DISPLAYING A "BATTERY TOO COLD PLUG INTO WARM" MESSAGE OR A CHECK ENGINE LIGHT. PERSONALLY, THIS IS THE SECOND TIME I'VE HAD A SENSOR FAIL. THE ENTIRE MODULE CONTAINING THE FAILED SENSOR MUST BE REPLACED. THE BATTERY IS MADE UP OF THREE DIFFERENT SECTIONS CALLED MODULES. WHEN A SENSOR FAILS, THE CAR WILL SIMPLY REFUSE TO START DESPITE BEING WITHIN A NORMAL OPERATING TEMPERATURE RANGE. I'VE HAD THE MESSAGE DISPLAY WHEN IN MOTION. THIS TIME HOWEVER, THE MESSAGE WAS ACCOMPANIED BY A CHECK ENGINE LIGHT, AND A BURNING ODOR THAT RESEMBLES BURNING PLASTIC WHILE THE ENGINE IS RUNNING. I HAVE YET TO EXPERIENCE REDUCED PROPULSION OF ANY KIND WHILE DRIVING.

SERVICE AIRBAG WARNING LIGHT NOW STAYS ON PERMANENTLY. DEALER INSPECTION REVEALS THE FRONT PASSENGER SEAT PASSENGER DISCRIMINATING SENSOR NEEDS TO BE REPLACED. ESTIMATED COST IS $900.00 +/- THIS SEAT HAS NEVER BEEN WET OR DAMAGED, THE VEHICLE HAS NOT BEEN IN ANY ACCIDENT WHERE THE AIRBAGS DEPLOYED.

PURCHASED CAR 5-31-12-RECEIVED GM'S '19 RECALL TO REPROGRAM HPCM TO ELIMINATE PPR SOME VEHICLES HAD. PRIOR TO SERVICE NO ISSUES. COOLANTS REPLACED SAME TIME.

ENG NOW RUNS RANDOMLY @ TEMPS BTW 40-65F. CALLED GM,COMPLAINED ASSIGNED CASE#9-56696768626&TAYLOR@866-790-5600X5916129. MULTI MSGS B4 CALL RETURNED. ADVICE-RETURN TO DEALER, DID ON 12-5-19 TOLD CAR FUNCTIONING CORRECTLY. CALLED GM VOICED DISCONTENT W/CAR SINCE RECALL SERVICE. TOLD GM RELIES ON DEALER TECHS TO DETERMINE IF CAR IS FUNCTIONING CORRECTLY. PER ADVISOR'S REC, TOOK 3RD TRIP TO DEALER. DEALER REP STATED CAR WAS WORKING CORRECTLY, SAID HE HAD COMPLAINTS FROM OTHERS AFTER RECALL WORK, ENGINE RUNNING DUE TO LOW TEMP, BATTERIES & RANGE DETERIORATE OVER TIME. REQUESTED CAR BE RETURNED PRE-RECALL STATE, TOLD NOT AN OPTION. EXPECTED BATTERY DETERIORATION FROM START, DIDN'T EXPECT GM/DEALER TO BREAK CAR, CAUSING 2 HAPPEN IN 1 DAY. PREVIOUSLY ENG RAN AT 24F W/SCREEN SHOWING RUNNING DUE TO TEMP. NO SCREEN NOW. CAR SPEED DROPS WHEN ENGINE ENGAGES, SAFETY ISSUE ON BUSY ROADS. WROTE GM 5/20 & DEALER 11/2020,NO REPLY. CAR DRIVEN <6K MI IN '20 DUE TO THESE ISSUES. DON'T TRUST GM/DEALER TO FIX CAR. GM SENDS ME TO DEALER SAYS CAR PERFORMING CORRECTLY. CAR NO LONGER CHRGS, INDICATES CHG SYSTEM SERVICE REQUIRED. AFTER 2 TRIPS TO GM DEALER, STILL NOT WORKING, TOLD BATTERY MAY NEED REPLACING. IF SO DAMAGE DONE BY GM DEALER & GM HPCM2 UPDATE. TOLD IN '19 BY OURISMAN REP UPDATE FIXED BATTERY CELL REBALANCING ISSUE. SINCE HPCM2 REPROGRAMMING MY CARS PERFORMANCE FUNDAMENTALLY CHANGED & SAFETY ISSUE WHEN ENGINE ENGAGES. GM SHOULD RECALL VEHICLES, FIX THEM MAKING OWNERS WHOLE SINCE IT IS THEIR SOFTWARE & DEALER SERVICE TECHNICIANS WHO CREATED SAFETY ISSUE.

THE DASHBOARD INSTRUMENT PANEL GOES BLANK IN COLD WEATHER. NOT ABLE TO SEE SPEED OR ANY OTHER INFORMATION.

MY "SERVICE AIRBAG SOON" LIGHT HAS COME ON FOR THE PASSENGER SIDE AND REQUIRES A REPLACEMENT OF THE PASSENGER PRESENCE SENSOR AND MODULE. I HAVE BEEN QUOTED BY THE CHEVY DEALER AT $897 BEFORE TAX. THIS HAS BEEN REPORTED BY MANY OTHER PEOPLE BEFORE. DUE TO THE SENSOR MALFUNCTIONING AND NOT KNOWING IF THERE IS OR ISN'T A PASSENGER IN THE SEAT THE AIRBAG MAY OR MAY NOT BE ACTIVE. THIS IS EXTREMELY DANGEROUS.

MY 2012 HAS A "SERVICE AIRBAG" CODE THAT POPS UP WHEN I START THE CAR. AFTER DOING SOME RESEARCH ON THE WEB, I'VE COME TO FIND OUT THAT THIS IS A VERY COMMON ISSUE, ESPECIALLY WITH THE 2012 CHEVY VOLTS. THE PROBLEM IS WITH THE PASSENGER AIRBAG SENSOR IN THE SEAT. THE REPAIR FOR THIS ISSUE IS VERY EXPENSIVE, AND I AFRAID TO HAVE A PASSENGER IN MY CAR. THIS SHOULD NOT BE AN ISSUE THE CONSUMER HAS TO PAY FOR OUT OF POCKET. THIS IS A SAFETY ISSUE. THANK YOU.

THE DRIVER'S INFO SCREEN (SPEED, ODOMETER, REMAINING FUEL, WARNING LIGHTS, TURN SIGNALS, SAFETY MESSAGES, ETC.) WENT BLANK WHILE I WAS DRIVING. IT INTERMITTENTLY COMES BACK ON, BUT GOES BLANK AGAIN.

PASSENGER SIDE AIRBAG SENSOR IN SEAT FAILING ON AND OFF FOR A COUPLE MONTHS, STEADILY GETTING WORSE AND LIGHT/WARNING COMING ON MORE OFTEN UNTIL IT'S CONTINUOUSLY FAILING. SEAT DID NOT GET WET OR DAMAGED.

AIRBAG SENSOR WARNING. 117K MILES. JUST CAME ON, DEALER WANTS $1100 TO FIX IT. AS THIS IS A SAFETY ISSUE GM SHOULD FIX IT FREE.

WHILE DRIVING SUDDEN LOSS OF POWER HAVING TO BASICALLY DEPRESS GAS PEDAL TO MAINTAIN SPEED WHILE SIMULTANEOUSLY RECEIVING "REDUCED PROPULSION ERROR". DEALER CLEARED ERROR AND DID A REPROGRAM. AFTER PICKING UP VEHICLE RANGE WAS REDUCED APPROXIMATELY 1/3RD BUT CAR RAN. SHAME ON ME FOR NOT BEING MORE FORCEFUL ABOUT RANGE REDUCTION BECAUSE THIS BATTERY WAS DEFECTIVE. THIS SUMMER JUNE 2020 COMPLAINED ABOUT REDUCED RANGE AND DEALER DID MORE PROGRAMING. NOW IN OCTOBER 2020 REDUCED PROPULSION ERROR CAME BACK AND HYBRID BATTERY IS BAD. WARRANTY RAN OUT IN MAY 2020 AND GM REFUSING TO ACKNOWLEDGE 2018 DATE OF DEFECTIVE BATTERY.
