Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Within the last month, my car has burned though 3 fuel pump relays. One connection is bubbling up in a certain spot. The fuse box is hot to the touch, and a glove was needed to pull the fuel relay out and the bubbling is now apparent on the fuse box itself. I had just finished a 260 mile round trip with my sister and when we stopped for food, the car would crank but not start.”

“Car was stationary fuel relay burnt out. We replaced it and new one went out. Thought it was fuel pump. Replaced pump and still wouldn't crank. Realised the fuse block is bad. Saw online where this is a common issue. We are having a hard time finding the correct block. Ordered one from GM online and it was the wrong one. Sent it back. Car has been down for over a month. This should be a recall.”

“Lost power while driving 65 MPH on highway which caused power steering and brakes to become hard to use. I took it to mechanic and found that the fuel pump relay had over heated causing the fuel pump to stop. I looked on recalls on the internet and saw where this has become a common problem with these cars and that general motors refuses to issue a recall. This is a very danervous condition and needs to be corrected.”

“Twice in the last twelve months there has been a short in the tail light assembly resulting in my battery getting drained. I could not get to my tools in the trunk because I could not get the electrical system to open the trunk and I could not open it manually. The short has been due to an electrical wire being pinched between a washer and the frame when the tail light assembly was replaced after a bulb was replaced. It caused my car to die while running.”

“Buick Lucerne electrical problems - onstar suspected. I 'm not sure that this is or isn't a safety problem, but after complaining to Buick I was advised by them to file a claim(?) with you. About a month to 6 weeks after an in-town accident (10/22/16) that was repaired immaculately by the local GM dealer, the car sat in a park and fly lot for about 5 days while we had gone visiting out east. When we got back the car was dead as a stone. …”
