2017 Chevrolet Malibu Hybrid

In 2019 I took my vehicle under warranty to the purchasing dealership to fix a "shift to park" reading after the vehicle is parked. It precludes turning off the car. Repeatedly restarting the car and shifting to park and/or jiggling the controller in park usually stopped the reading. The dealer replaced the control shifter, which fixed the problem for many years. This August, the problem started recurring and I have been attempting to make an appointment in the last week, but none of the local dealers say they can repair this for some time. Most cannot even diagnose the problem for a week or two.

the secondary battery that sits in the trunk, above the back driver side tire had a short. the cable bunt out and my car reduced speed and it had me pull over. I did not know this is what had happened until i drove it again and i could no longer start it. the shift knob is locked and cant put it on drive or neutral. initializing wait to shift, theft deterrent system, transport mode on, stabilitrak, among other things popped up. Had that short sparked up into an actual fire, yes, my life could have been at risk as the car could have caught on fire. Due to it being a long weekend (memorial day weekend) I couldn't take it to a Chevy dealer. I am on an out of town trip for my kids soccer tournament. i currently have it sitting a tow yard waiting to take it to my house, and then towed to Chevy dealer in Hemet, CA, where I live.

The contact owns a 2017 Chevrolet Malibu. The contact stated that after his wife parked the vehicle, the "Shift to Park" message was displayed while the gear selector was shifted into park(P). The vehicle would not turn off until after several attempts; however, the failure recurred with the doors locking the contact's wife and 3 children inside of the vehicle. The contact's wife was able to turn off the vehicle while the brake pedal was depressed and the Start/Stop button was pressed and unlocked the doors with the key fob. The dealer was made aware of the failure and sent a tow truck to retrieve the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 57,733.

Car voltage stays very high (between 14.8 and 15 volts) for extended periods of time. At which point the windows have fogged up and there is a raw egg smell in the cabin - probably Sulfur. Both the hybrid and the 12v car battery are located in the truck and there are vents that draw air from the cabin to ventilate those batteries. The car voltage will also stay at 12.5 to 12.6 for extended periods of time. During both high and low periods numerous internal systems have failed, including bit not limited to steering assist, anti-locks bakes, Stabilitrack, On star, Hybrid Control Processor and ECM. Car has been brought to the dealer 3 times. First time (early November 2021) it was diagnosed with an hybrid inverter and a software update was installed. Issues continued. As of 12/28/21, Coggin Chevrolet (Jacksonville, FL) has had the car for 2 weeks and can't fix or confirm what is wrong with the car. I have received numerous e-mails from On-star with engine error codes as well as 5 messages saying there is an issue with the Electric Drive Unit in the car. The car has roughly 24K miles on it.

HYBRID BATTERY CORROSION DUE TO FAULTY BRAKE LIGHT LETTING WATER INTRUDE INTO TRUNK. I WAS OUT OF COUNTRY FOR MOST OF 2019 AND WHEN I RETURNED I WENT THROUGH MAIL AND DISCOVERED A LETTER FROM GM STATING THAT WATER CAN GET INTO TRUNK AND CABIN FROM A CHMSL. I CHECKED MY TRUNK AND IT WAS FULL OF WATER AND METAL ITEMS ARE AND WERE OXIDIZED AS WELL AS THE HYBRID BATTERY IN THE TRUNK. THIS CORROSION WILL NOT STOP ONCE ESTABLISHED ESPECIALLY WITH CHARGED ELECTRONIC COMPONENTS. AND PREMATURELY SHORTENING THE LIFE OF THE HYBRID BATTERY DUE TO POOR QUALITY AND DEFECTIVE NUTS USED TO SECURE THE CHMSL.

TWO TIMES IN 24 MONTHS AND APPROXIMATELY 62,000 MILES THE PRIMARY 12 VOLT BATTERY HAS FAILED. THIS FAILURE CAUSES THE TRUNK LOCK TO BECOME INOPERABLE. THE TRUNK CANNOT BE ACCESSED IN THIS SITUATION. BECAUSE THE TRUNK WILL NOT OPEN THERE IS NO ACCESS TO THE FAILED 12 VOLT BATTERY. ALSO THERE IS NO WAY TO FOLD THE REAR SEAT BACKS AS THE RELEASE LEVERS ARE LOCATED IN THE TRUNK. THIS SITUATION IS BOTH A SAFETY DANGEROUS HAZARD AND INCONVENIENCE. BOTH OF THESE OCCURRENCES HAPPENED WHILE THE CAR WAS PARKED IN OUR GARAGE.

WITHIN 1 YEAR I BOUGHT BRAND NEW HYBRID MALIBU CAR FROM CHEVY DEALER, I HAD EXPERIENCED DEAD 12V BATTERY. DEALER REPLACED THE BATTERY WHICH I PAID EVEN THOUGH I THOUGHT IT SHOULD BE WITHIN WARRANTY. LAST NIGHT I EXPERIENCED 3RD DEAD BATTERY AGAIN AFTER I PARKED THE CAR FOR 7 HRS OFFICE WORK. THE 2ND TIME DEAD BATTERY OCCURED WAS LAST JUNE 2019 ONLY, DEALER ALSO REPLACED THE BATTRY. ITS A 3RD TIME THAT I EXPERIENCE DEAD BATTERY (STATIONARY/PARKED) FOR BRAND NEW CAR 2017 HYBRID MALIBU WITHIN 2 YEARS. OBVIOUSLY ITS NOT THE BATTERY ISSUE BUT ITS DESIGN OF ELECTRICAL SYSTEM. BEFORE AND DURING THE BATTERY ISSUE, I GOT STABILITRAK LIGHT ON AND STEERING ASSIST IN REDUCED ALARM AS WELL. I JUST WANT TO VENT MY FRUSTATION WITH THIS BRAND NEW CAR. HOPE OTHER CAR OWNERS WILL BENEFIT FROM THIS INFO. FOR 10 YEARS I NEVER HAD BATTRY ISSUE ON MY PREVIOUS CAR. THANKS

AFTER TRIP OF A FEW MILES AND AFTER TURNING OFF THE START/STOP(KEYLESS) SWITCH, THE SCREEN MESSAGED THAT THE REMOTE KEY WAS NOT DETECTED, EVEN THOUGH IT WAS STILL IN THE CAR. NEITHER REMOTE KEYS WOULD NOT PERFORM ANY FUNCTION NOR WOULD MANUALLY PUSHING DOOR LOCKS OR SWITCH. AFTER ABOUT 20 MINUTES REMOTE KEY OPERATION RETURNED.THIS HAPPENED AGAIN ABOUT 2 WEEKS LATER. THE DEALER CANNOT FIND THE PROBLEM. I AM WORRIED THAT THIS WILL STOP THE ENGINE IN A CRITICAL SITUATION.

THE CAR SOMETIMES HAS A HUGE DELAY AFTER YOU PUSH THE START BUTTON ON DASH TO ACTUALLY START, AND BEING A HYBRID THE CAR SHAKES BAD WHEN ENGINE STARTS, IT'S SOUNDA LIKE CRAP TO BE HONEST. I'VE GOT 12K MILES ON IT AND IT'S BEEN SERVICED AT CHEVY ONLY, AND THE [XXX] THING HAS A RATTLE IN THE DASH THEY 'CAN'T FIGURE OUT' AND THEY DON'T HEAR ANY ABNORMAL ENGINE NOISE. AND THEY SAY IT'S NORMAL TO LAG THAT BAD WHEN STARTING, AS IT HAS TO 'POWER UP'. BUT WHEN CAR WAS NEW IT DIDN'T DO THAT PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
