2017 CADILLAC ESCALADE Vehicle Speed Control Problems

The contact owns a 2017 Cadillac Escalade. The contact stated while driving at an undisclosed speed, there was an abnormally loud clunking sound coming from the vehicle and the vehicle then decelerated to 30 MPH. The check engine warning light was illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the transmission needed to be replaced. The vehicle was replaced, but the failure recurred. The vehicle was taken back to the local dealer, who recommended replacing the valve body. The part was on backorder, and the vehicle was not repaired. The manufacturer was contacted and opened a case. The approximate failure mileage was 85,000.

While driving on Highway 360 in Arlington, TX, the engine appeared to not change gears. It was between 3:30 to 4:00 PM, moderate traffic. I left HWY 360 and used the side lane. Later, the engine light came on. I checked the fluid levels and all were fine. This vehicle was last serviced in December 2022. The problem is unknown.

Transmission had to be replaced at around 10k miles and covered by warranty. •no lights indicating any problems. Forward collision alert activated. Vehicle has a lag between the time pressure is applied to the gas pedal and it causes a delay in acceleration resulting in the vehicle sort of lunging forward unexpectedly. About 15-20 seconds after the gas pedal is pressed it will have a sudden burst of quick acceleration. It only lasts a few seconds and there’s no time to correct the sudden acceleration by braking. I finally realized the seriousness of the issue after I very close to being in an accident today as a result of the delayed acceleration. I was stopped at a red light and pressed the gas once it turned green, another driver happened to change lanes as soon as we crossed...
