2022 Buick EncoreTransmission & drivetrainAcceleration & cruise control

I have had my vehicle to a GM dealer on a few occasions with the EMC code stored in the vehicle and an active check engine light on. While I'm driving - now during 70 percent or more of my trips - my vehicle loses power very suddenly and lunges me forward. I'm unable to stop and go on hills of any noticeable grade and have narrowly missed being in an accident many times. The dealer's service manager has told me I should just BF glad the car is drivable when I have expressed ongoing safety concerns. I cannot get...

2018 Buick EncoreSteeringAcceleration & cruise controlBrakes

While driving, my car began to glitch out. The screens started turning on and off, the doors began locking and unlocking, and I lost my ability to steer, brake, and accelerate. It caused me to run a red light and I almost got into a severe accident. This issue has occurred several times, and during more recent occasions the car has turned off completely while driving. There were no warning lights or messages indicating that something was wrong with the car, but sometimes when I turn the car back on, it says "calibrating." If Buick has sold cars that are capable of losing complete control, this should be investigated immediately.

Unknown issues w/ sensors and wiring lead to turbocharger failure. This led to spontaneous acceleration issues on the highway. Less than a year after the warranty covered the replacement of the turbocharger (less than 60k miles on the car) the turbocharger again failed (64k miles on car).

2019 Buick EncoreSteeringAcceleration & cruise controlDriver assistance

My radar to let me know i was going to hit something didn't go offer. It has never failed before and has been overactive actually which I appreciated before. I was doing 60 with my paraplegic wife (luckily not our 5 year old as well though) in the right lane because it's safer to go slower and be there. I was distracted by a strange machine being transported on a truck to my left. This was my fault. I hear the ultimate responsibility and the majority if not all of it. I saw the road construction trucks 400 feet...

ahead of me at most. Maybe less than 300 and luckily no one was to my right the truck distracting me was ahead so I had room to avoid hitting the construction truck with the sign saying move over. It was doing maybe 15. I almost killed my wife. It was my fault but still the $3000 safety package failed. Almost catastrophically.
