2017 Chevrolet Bolt EV Engine Problems

I am reporting a safety issue involving the high-voltage battery system of my vehicle. Vehicle: 2017 Chevrolet Bolt EV VIN: [XXX] Mileage: 87,125 miles The vehicle has generated a P302F diagnostic trouble code, which indicates high-voltage battery cell imbalance. This condition may pose a safety risk related to battery performance and thermal stability. The authorized Chevrolet dealership has refused to diagnose the issue under warranty unless I pre-authorize a $600 diagnostic fee. The vehicle is covered under an active GM buyback warranty and a 10-year / 100,000-mile battery warranty due to a recall battery replacement. Due to the safety implications of a high-voltage battery fault, I believe refusal to diagnose the issue under warranty may pose a risk and warrants review. I am submitting this complaint to document the issue and request investigation. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I own a 2017 Chevrolet Bolt which is part of the recall announced today by GM. This is the second recall in less than a year for the same battery-related issue. It was supposed to have been fixed with a software update in June. This software was supposed to identify defective batteries but it has not been successful as evidenced by the mounting number of fires that have happened after the “fix”. As such, we are now under a recall a second time. As a result of their own manufacturing issue, we are now limited to how we charge our vehicles, where we park and even the mileage range that we paid for, while GM attempts another fix. GM stated today that they will again be using software to identify defective cells in our batteries and only the ones that are deternined to be defective will have those cells or battery packs replaced. As you can imagine, I no longer trust GM to be able to successfully identify whether or not my battery is defective. I’m extremely disappointed by the fact that GM continues to cut corners in an effort to save money, despite such a serious safety issue that can affect so many. Myself, my livelihood and even people I park next to while out in public are at risk. GM must be forced to replace the entire battery pack in every vehicle affected by this recall. They must also provide loaner vehicles, or details on reimbursement for rental cars, to those who need them due to the fact that their vehicle is virtually unusable while they clean up their mess.

THERE WAS A RECALL ON CHEVY BOLTS EV 2017, BECAUSE A FIRE OCCURRED. CHEVY ADVERTISE THAT IT CARS GET 234 MILES ON A FULL CHARGE. THIS IS NOT TRUE AND FALSE ADVERTISING FROM THE GMC MANUFACTURER. SINCE THE RECALL AND THE VEHICLE HAD TO BE RECALIBRATED TO 90 PERCENT, THE CAR GET MUCH LESS THAN 234 MILES . THIS IS IMPORTANT BECAUSE THIS A ALL ELECTRIC CAR. IS THIS NOT FALSE ADVERTISEMENT?

WHILE SLOWING TO MAKE A STOP AT AN INTERSECTION, THE VEHICLE EXPERIENCED SUDDEN ACCELERATION AND WOULD NOT STOP. THE CAR STRUCK THE VEHICLE IN FRONT OF IT A COUPLE OF TIMES AND CONTINUED TO ACCELERATE.

I EXPERIENCED A FAILURE OF THE 12-VOLT BATTERY. WHEN THIS HAPPENS, THE VEHICLE LOSES POWER, STALLS, AND THEN IT LOOSES ALL FUNCTIONS - CANNOT BE EVEN SHIFTED INTO NEUTRAL TO MOVE IT, CANNOT OPEN REAR DOORS. WE COULDN'T EVEN GET IN ON A TOW TRUCK.

CAR SUDDENLY LOST POWER ON THE HIGHWAY. I HAD TO COAST TO A STOP. THE HIGH-VOLTAGE BATTERY WHICH HAD BEEN 3/4 FULL WENT DOWN TO ZERO. AFTER THE INCIDENT, THE CAR COULD NO LONGER BE DRIVE. I'D ALREADY HAD GM'S RECALL INSTALLED N172127150
