Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Twice after filling up with gas, my car was oils not start at the pump. Each time I had to wait several minutes before it would actually start. The second time it happened, I waited, it started then immediately quit again. There is a very hard start when it attempts to start as well. The engine light came on then immediately went off. I took the car directly to the dealership where it had to remain running until they could get it in. This was 540p on friday, may 25th before a holiday.”
NHTSA complaint #11098066, filed 2018-05, 73,704 miles“The truck pops all the way open/up when the car is turned off or while I am driving at a slow speed. It has happened so many times but I can not duplicate it so I can get it fixed by GM.”
NHTSA complaint #10781174, filed 2015-10, 25,881 miles“This vehicle stalls/cuts off while driving. It can occur while driving or taking off from a stand still. It maintains a stored history code p0014 and after service will reappear. Especially dangerous while driving in the national capital area. Buick has a notice about the engine control module and that has to be reprogramed for that vehicle model and my VIN number falls within that bulletin. The problem is that it doesn't work and the vehicle shuts off at a moments notice. Right now I'm afraid that my life or someone else is ir real danger. Unfortunately I'm not the only one. …”
NHTSA complaint #10970289, filed 2017-04, 100,000 miles“When turning left at a traffic light, my car lost power and I wasn't sure I was going to make it around the corner. After a few seconds my car regained power. 45 minutes later, I made a right turn into heavy traffic and then felt a sudden lurch. I looked in the rear view mirror and saw that my trunk had popped open. I managed to get off the highway, parked the car and turned off the ignition. I got out, closed the trunk, got back in the car, and fastened my seatbelt. Before I could close the door, the trunk popped open again. This occurred three times before the trunk finally stayed closed. …”
