2017 CHEVROLET BOLT EV — Problems, Recalls & Safety Data

Sometimes, when driving in a turn, either direction, and hands are released from the steering wheel, the vehicle does not return to center. Force is required to cause the steering to begin returning to center. Once it begins returning to center, seems to always continue to center. This is a dangerous departure from decades of common vehicle operation. An unsuspecting driver can drive into an obstacle or people.

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)

Vehicle started to surge while driving (both small acceleration forward and large deceleration) without any change in brake or accelerator position. Eventually a "Propulsion Power Reduced" message was presented on the console followed immediately by no forward propulsion (accelerator completely unresponsive) and forced to coast to a stop on the side of the highway. Car refused to shift out of park or neutral following breakdown. Car taken to dealer to troubleshoot and was told that a P0A3F code was present and that the engine harness needed to be replaced in accordance with NHTSA bulletin 19-NA-220. This bulletin calls out that the harness was likely damaged during initial install at factory and the dealer representative confirmed that the pins were damaged as described. Car was given back to drive home after harness was checked (owner decided to explore options before scheduling repair), but broke down due to surging and complete loss of power within 2 miles of dealer. Troubleshooting to confirm harness damage is suspected to have worsen the condition and made un-commanded accel/deceleration followed by complete loss of power likely. Uncertain why this condition would be exempt from recall if OEM is aware of installation issues at factory. Driving with this condition was as bad or worse than other type model loss of power conditions that have been recalled. Recommend at least clarifying that cars confirmed to fall under this bulletin and associated inspection should not be deemed roadworthy until a repair is made.
