2017 Chevrolet Bolt problems

“The steering wheel fails to return to center after turning and will stay stuck in the turned position. In looking through forums, it appears to be a common issue for Bolts that Chevrolet has not taken accountability for as no recall has been issued even though the complaints are quite numerous with the steering gear needing to be replaced, even at low mileage.”

“The contact owns a 2017 Chevrolet Bolt EV. The contact received notification of NHTSA Campaign Number: 21V560000 (Electrical System); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. Parts distribution disconnect.”

“While driving the car it suddenly, and without warning, abruptly slowed to a stop and the display showed "propulsion power is reduced", then the "service soon" symbol came on. This could have happened in fast moving traffic, which definitely could cause multi-car collisions. The GM service bulletin (Document ID: 5409616, revised February 13, 2023- see attached copy) states that this is likely due to "a spread terminal on the vehicle harness connection X2 on the T12 transmission assembly. The terminals may not have been perfectly aligned during installation at the vehicle assembly plant." This is a known, dangerous, malfunction, and GM has not issued a recall for it. The "correction" is to replace the "engine wiring harness" which goes to the EV motor. GM is also not covering this repair under any extended warranty, although it's a safety issue and really should generate a recall. Please see attachment.”

“While at a remote location, I unlocked and entered the vehicle normally. When I tried to start the vehicle, numerous unrelated error messages appeared on-screen. The instrument panel was energized, but the vehicle could only shift into neutral and park. Power steering was lost, as was window functionality. The vehicle could not be fully started, nor could not it be fully shut off either. It was stuck in a peculiar, unsafe, and unresolvable state of energized limbo. AAA towed the car to Watson Chevrolet who determined that the 12v system (vs propulsion) battery malfunctioned and needed to be replaced. There is no information in the owner’s manual about this issue. The tow truck mechanic had no clue what was wrong. Fortunately, we were in a safe location. But under different circumstances, such as being roadside, this could have been a very unsafe situation. This is the original battery. The car was recently serviced and there was no indication the battery was failing. This problem was only an annoyance for us, but it could have been much much worse under less favorable circumstances.”

“In Sept 2020, GM issued Service Bulletin 20-NA-170 regarding rapid popping or clicking noises coming from the I-Booster hardware under the hood in the braking system. Earlier fixes for this issue involved replacing the I-Booster hardware, but that didn't solve the problem. The new fix called for a software update to the Brake Booster Control Module. The Bulletin states: "Correction -- DO NOT replace the I-booster assembly. Update the Brake Booster Control Module with the latest software." I reported this brake/electrical system issue to NHTSA on April 24, 2022 (# 11461966) and January 25, 2023 (# 11503678), and have had no response or investigation by NHTSA regarding the hazard of this software defect. When the hardware eventually fails--and it will due to 1000's of unnecessary use cycles--what happens to the braking system?”

“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.”
