Example complaints

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

“Abs, traction control light and hill descent light stays on. The ABS brakes are not working. The dealer told me that my brake fluid was not changed according to recommended warranty standards. I've done some research and found that others who own this vehicle have also had ABS module malfunctions or defects.”

NHTSA complaint #10167467, filed 2006-09, 60,000 miles

“The first issue is about a seat fire. My husband was just pulling into our drive when the drivers seat heater burned a hole in the left side of the seat causing him to have a burn. The second problem is the oil pump. I heard a noise coming from the engine, and asked our mechanic what might have been the cause of the noise. He said the the oil pump was bad and we will have to replace the oil pump and if there was damage to the engine would have to replace that too. I understand that there was a technical alert dated march 14, 2003, just three months after I purchased my car. …”

“I have 2003 Land Rover, Discovery car that requires constant replacement of the navigation system and its radio/cd player. This is my fifth replacement since the purchase of the car. In addition to this, the engine oil constantly leaks...took it in for repair numerous times but the problem continues. The engine light is always on....took it in a few times and the dealership repair center said it was an electrical sensor problem. The brake and ABS lights would come on and go away on its own. Since march 2010, the brake and ABS lights decided to stay lit. …”

NHTSA complaint #10326500, filed 2010-04, 102,000 miles

“Was moving very slowly - in a parking garage. Began pulling into a space and applied brakes. Engine revved (throttle opened?) and accelerated by itself a few feet in to a wall. Given that it was only a few feet and a large cement wall, no major damage. My foot was firmly on the brake, the brakes were squealing and there were witnesses and probably video given that it is a parking garage. Burning brake smell also very apparent. I work in insurance and know of this sort of claim. I did not move my foot, opened the door and looked, foot firmly on the brake. Floor mat was not a factor.”

NHTSA complaint #10428271, filed 2011-10, 83,000 miles

“I parked my landrover Discovery in the grocery store parking lot, pulled the key out and walked toward the store. After a crashing noise I turned around to see my car had rolled back into a van. My transmission was still in drive and I had been able to remove the key from the ignigtion. I called my landrover dealer. After explaining what happened I asked why the key could be removed in the drive position, he said he didn't know and would have to look into it. He then directed me to the collision center for repairs. …”
