general problems of the 2017 Buick Lacrosse

My 2017 Buick Lacrosse premium awd experienced a sudden, dangerous mechanical failure of the accelerator pedal position sensor system while operating the vehicle under normal road conditions. The vehicle suffered an immediate loss of engine continuity and engine power, forcing the car into a hazardous low-speed limp mode while in active traffic. A certified repair facility inspected the vehicle, confirmed a complete failure of the internal pedal sensor circuit, and replaced the unit to restore safe operating throttle control. This specific electronic and mechanical defect represents a widespread manufacturing vulnerability that general motors has officially acknowledged under special coverage adjustment n182188250. This failure poses an immediate safety hazard to occupants and surrounding traffic, as a sudden drop in throttle response on highways or busy intersections leaves the driver unable to maintain safe traveling speeds or accelerate out of oncoming hazards. General motors has opened corporate case #113840289 regarding this failure but has failed to issue my safety reimbursement.

Vehicle loses power every GMC vehicle I have owned (3) seen to have this issue throttle pedal position sensor while driving on the interstate vehicle speed drops to reduce engine power which is very scary and dangerous.

The contact owns a 2017 Buick Lacrosse. On several occasions, while the vehicle was idling thirty seconds to a minute with the brake pedal depressed, the vehicle revved and independently accelerated. There were no warning indicators illuminated. The vehicle was taken to cooper Chevrolet Buick (1300 s quintard Ave, anniston, al 36201, (256) 405-4155) where no diagnostic failure codes were found and the failure could not be duplicated. The vehicle was not repaired. The manufacturer was not notified. The approximate failure mileage was 1,500.
