2019 Buick LACROSSE HYBRID - Ratings, Complaints and Recalls

"in october 2021, while driving, the car lost power. several indicators displayed at the time, including: • service engine • service stabilitrak • service antilock brakes • service transmission i managed to pull the car to the side of the road and restart it, but it was stuck in first gear. after several restarts it performed normally. i took the car to miller & sons, they told me they could not find a code and the car was performing normally at that point so there was nothing they could do. they told me if the car did it again, to bring it in immediately so they could get a code for the malfunction. two weeks later, the same malfunction occurred, i took the car directly to miller & sons. once again i was told they could not find a code or problem and i was sent away again. the third time this malfunction occurred, i was driving at 40 miles an hour and the car began to accelerate on its own. i could not brake, shift to park, shift to neutral, steer or apply the emergency brake. after about 15 seconds, the car shut down in the middle of the road. it could have caused death or seriously bodily injuries to me or others. at this point i had the car towed to miller & sons. i am told that while test driving the vehicle, it also accelerated on the mechanic [xxx], almost causing an accident again. at this point the told me they found 60 codes dating all the way back to the first incident, but they still did not know the problem, they replaced the transmission control module in hopes that would solve the problem. it did not. in august, the same thing happened. they replaced the transmission control module again. about a month ago (september 13) it happened two more times. it is still sitting at miller & sons. this time i contacted gm for some assistance. i was using the messaging system (case number [xxx]) i was told a senior advisor was assigned to my case and that a tac team would consult with the dealership to diagnose and correct the problem.... information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)."

"i own a 2019 buick lacrosse e-shift (vin#[xxx]). over the last 4-5 mos. i have had 3 incidents where the e-shift mechanism has gone into park without touching the shift control. 1. first occurrence - approx. 5 months ago car was in drive at very slow speed entering parking slot with foot lightly depressed on brake. car changed to park on it's own. stopped abruptly, gears grinding, jerking me toward steering wheel. 2. second occurrence - around 10/10/20, car was in drive, foot lightly depressed on brake, waiting to make left turn at stop light. car changed to park on it's own. again the car stopped abruptly, gears grinding, jerking me toward steering wheel. i scheduled appointment with dealer maintenance on 10/13/20. they could not replicate the problem. asked for me to return the car so they could have overnight. due to covid escalation have not scheduled appt. 3. third occurrence - on 12/11/2020, i was waiting at a red light, car in drive, foot fully depressed on brake, and the car shifted to park on it's own. i heard the car locks click, and wondered what caused that. when light changed and i tried to accelerate, the car did not move, and it was then i noticed it was in park. i intend to take the car back to the dealer for them to see if they can replicate. they had nothing in their database on 10/13/2020 reflecting other complaints. i'm somewhat skeptical they can replicate due to the random occurrences. but it definitely seems to be in the shift park component of the car i am now very hesitant about driving this car. since it happens randomly, and abruptly, with no forewarning, i am concerned for my safety. my questions are: 1. has anyone reported a similar problem to your group? 2. what other information do you require? 3. what other actions should i take? 4. what other groups can i contact to inquire about the problem? information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr"
