What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I was driving the car all day and just had jumped back on highway doing around 65mph and all of a sudden the car threw itself into first gear it felt like and started accelerating on decelerating on its own jerking very violently if I wasn't wearing my seatbelt I would of went through the front windshield because it…
I driving on I-20 west going approximately 70 mph when right rear tire blew. I stopped in emergency lane and my car wouldn't stay cranked. There were 7 wires that were cut in half. I couldn't crank car because the wires went to fuel system and had to have car towed and someone travel 3 hrs one way to pick me up.
This car has the same or similar electric power steering pump that gm is now recalling for other models. The power pump will just stop working and then it will start working again. It usually stops working at low speeds making it extremely difficult to turn.
While my wife was driving vehicle lost power while driving just after purchase from (lia infinity) dealership in albany, ny. Requested dealer take vehicle to cadillac dealer for checkout which he said was done and returned without repair. Condition was intermittent and was therefore difficult to diagnose.
Consumer writes in regards to rusted stabilizer bar bolts. The consumer stated the vehicle made a knocking noise, when he made a left or right turn. It was discovered that one of the bolts had broke in half.
My concern is plastic headlight lenses. The plastic lenses deteriorate to the point that they cloud over and become yellow, drastically reducing there effectiveness in lighting the roadway at night or during inclement weather. How did the auto makers convince the nhtsa that plastic lenses were safe ?
