2017 Chevrolet Bolt EV engine problems

Filed Jun 11, 2026 · Brakes, Engine · IL · crash

While slowing to a stop, the vehicle suddenly experienced multiple (3–4) violent jerks. The vehicle fought against my firm brake pedal application, overpowered the brakes, and accelerated uncontrollably, resulting in a crash. During the impact: • The driver frontal airbag and pretensioners deployed. • The driver seatbelt unlatched mid-impact and then locked/retracted in a way that prevented it from latching again, even while I was sitting in the driver’s seat post-crash. I have only been provided with the limited Airbag Control Module (SDM) data, which shows the brake switch as “Off” and low accelerator pedal readings. This data does not match the events I experienced. I have formally requested full downloads from all other modules (Powertrain/PCM, ABS/EBCM, BCM, etc.) from both the insurance company (ESIS) and GM, but they have only provided the single SDM report. This appears to be a sudden unintended acceleration event combined with a brake override failure and seatbelt restraint system malfunction.

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)

The battery has the potential to catch fire while it is charged or parked. The given precautions provided by GM makes the car unreliable and unusable. The battery and the vehicle is on usable due to its limitations based on charging. GM has no remedy for this vehicle.

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 have been more vehicle fires after the safety recall "fix". General Motors has not said anything yet, and I am afraid to use my car or leave it near anything because of fire risk. This is a great safety concern for myself and others around me. I would like GM to say something.

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?

My vehicle is impacted by the following recalls: 1) manufacturer recall number n202311730, and 2) the federal safety agency recall number 20v701. A fix was supposed to be in place by january 1. I followed the manufacturer's steps to reduce charge capacity and waited patiently until 1/29 for the fix. On 1/29 I called gm concierge line at that time to inquire about the status of the fix. I was told there was no update. I inquired about my options including a buyback or replacement vehicle in addition to a loaner car during the period of time the car was out of commission. I was told no problem and someone would contact me. I've received two calls since that time, and none of the promised steps including buyback, replacement vehicle, or loaner cars were offered. The representatives do not respond to my emails, when I call, the assigned rep ignores my calls, and when I ask for a status update I'm told there isn't one. Gm is clearly delaying the issue. I have informed gm that my vehicle is parked in a very close quarters garage where a fire would create an imminent life/safety issue. Gm continues to not respond to my inquiry. The vehicle meets the requirements of the nonconformity vehicle under the tanner act and I am requesting assistance to ensure that the vehicle is repurchased or replaced. There has already been confirmation posted that the battery packs need to be replaced on these vehicle and gm is not acknowledging their responsibility to issue a fix to the vehicle and prevent further injury. I am writing to request an inquiry by the federal safety agency into what gm is actually doing to prevent further loss of life and/or injury and to repair or replace my vehicle. I have documented weeks of emails on the topic with gm which are not being replied to and am not sure where else to turn to get gm to address this open safety issue. Thanks.

In november 2020, general motors has decided that a defect which relates to motor vehicle safety exists in certain 2017-2019 model year chevrolet bolt EV vehicles. This notice applies to my vehicle, VIN: [xxx]. As a result, gm is conducting a safety recall, n202311730. More specifically, a certain number of these vehicles were built with high voltage cells produced at lg chem?s ochang, korea facility that may pose a risk of fire when charged to full, or very close to full, capacity. The severity of the recall notice was alarming to my family as we drive it daily and often extended miles. Safety is my primary concern and I am requesting remediation immediately. The risk and danger is too great for me to wait and see as gm investigates. What recourse do I have now?
