When I get to a stop sign, and a stop light, when trying to accelerate after a complete stop, the car would struggle to accelerate to go forward. Where the shifting gears would start blinking, and the warning lights (engine power reduced, engine light, and the traction safety collision light) would display itself making it misfire and impossible to even go forward while pressing the gas pedal. It put me and other drivers at a safety risk because it would roll backwards after taking my foot off the breaks to accelerate where it would almost hit drivers behind me at the stops as well as them almost mistakingly hitting me in the back when my break lights stop reflecting when trying to accelerate at stop lights with traffic.

The contact owns a 2018 Buick LaCrosse. The contact stated the hand controls were not working properly. While driving, the accelerator pedal was depressed, but the vehicle failed to respond. The engine power reduced message was displayed, and the check engine warning light was illuminated. After several attempts, the codes were reset, and the vehicle worked as designed. The contact linked the failure to the Special Coverage Campaign: N182188250. The vehicle was taken to an independent mechanic who disconnected the hand controls and informed the contact that the controls were operating as designed. The vehicle was taken to the local dealer, where it was diagnosed, and determined that the accelerator pedal position sensor needed to be replaced. The vehicle was repaired, but the failure recurred. While driving at 55 MPH, the vehicle lost motive power and decelerated to 15 MPH. The message “Engine Power Reduced” was displayed, and the check engine warning light was illuminated. The vehicle was taken back to the same local dealer, where it was diagnosed and determined that the accelerator pedal position sensor needed to be replaced; however, the failure persisted. The manufacturer was contacted, and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 26,600.
