Example complaints

“There was an oil smell while my car was running and the passenger side of the defrost stopped working. I took the vehicle into my mechanic. My mechanic told me that there was a lot of oil leaking onto the engine and it was not safe to drive it until this leak was fixed. I left the car at his shop while the parts were ordered. …”

“I went out to start the car to go to work and I heard a backfire, my husband came out wondering what that bang was. Smoke started coming out from the hood. He popped the hood to see what the problem was and flames came shooting out from under the hood. He closed the hood to smother the fire, we had to call the fire department' to put the fire out. The car is a total loss. Now we are without a car. Now what!!!! This car was well maintained and great working order before this happened.”

“Engine of my 2001 Buick le sabre, v6, 3800 engine, caught fire after an oil change and short drive home. Authorized mechanic diagnosed it as engine oil leaked out of gasket and on top of exhaust manifold, triggering a fire that quickly melted the plastic wire harness cover and started burning through the wires. I caught the fire early as it was in my driveway and I had a fire extinguisher but fire was spreading quickly. I am unable to afford the repairs.”

“Our Buick had been running fine, but went to move it one morning. With a cold engine, as soon as we hit the starter, the engine exploded very loudly and started burning. After the fire was put out, it was determined that the entire intake manifold, along with the fuel lines had exploded in many pieces. From internet research, it was found that the fuel pressure regulator had a recall for vehicle years '98-'00, which these models had the same condition. Had I had the hood open at the time, I'd probably been hurt by flying chunks from the intake manifold. …”

“Engine will shut off upon exelleration at highway speeds between 45 - 55mph. And became more frequent over time at lower speeds. Was able to restart vehicle after sitting a couple of minutes from the start of the problem. But over time, it became more frequent and harder to restart with each incident. I've taken it to 1-dealer and 2-shops for diagnostic but, they could find nothing. I parked the car for a couple of months. Went out to start it one morning and it back fired with lots of black smoke coming from under the hood. Always stayed on maintenance schedule and the car runs like a champ! …”
