What owners report
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 accelera
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 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 acce
The 3.6 liter engine in my 2018 Buick Lacrosse Avenir only has 53,939 when we experienced a thermostat failure. The engine temperature was dead cold, and the dual electric fans were running non-stop. When I scanned the trouble code, I found PO128 which points to a faulty thermostat. Because the thermostat is buried under the intake manifold, we had the local Buick dealership replace it at a cost of over $800.00. I don't feel that a car with so few miles should be experiencing a thermostat failure. But this seems to be a common problem with the GM 3.6 liter motor according to a number of Buick forums that I read after the problem occurred.
The contact owns a 2018 Buick Lacrosse. The contact stated while driving at an undisclosed speed, the vehicle hesitated to accelerate while the accelerator pedal was depressed. The contact pulled over and checked underneath the vehicle. The contact discovered that the START/STOP accumulator endcap bolt had detached, causing transmission fluid to leak onto the ground.
