Example complaints

Engine cooling: “With respect to my 1999 Pontiac transport van, october of 2003 the engine started overheating and we discovered that the coolant was low. We added coolant and some type of seal into the coolant because we were told by several GM mechanics that it was probably the head gasket and this seal would help to get us by until we could have it fixed. I called the company where I purchased the van (2nd hand) and the van was no longer under warranty (over by 4,000 miles at the time). I did purchase the extended warranty. …”

NHTSA complaint #10061990, filed 2004-03, 44,000 miles

Seat belts: “The contact stated while traveling 40 MPH, the vehicle went off the road and struck a tree. When this occurred, the front driver side seatbelt shoulder strap did not lock. The driver hit the steering wheel causing minor chest injuries, then the airbag deployed. Also, the middle row driver side seatbelt came unlocked. This caused the occupants leg to be crushed, resulting in surgery. There was a police report taken at the scene. The vehicle was towed to a salvage yard and inspected by the manufacturer, but it was determined not to be a defect.”

NHTSA complaint #10154440, filed 2006-04, 57,000 miles

Brakes: “The engine has been making a clicking sound or drumming sound for quite a while now. I have taken the van into the dealer on a number of occassions. I have since learned that my van is not the only van to make this noise, and that some vans have had the engine replaced because of it. Something about the pistons and wall chamber. The van has also quite running while I was driving w/children, and when braking, an awful loud noise comes, sounds like the car is falling apart. I refuse to take the vehicle back, and am having loads of problems dealing with this.”

NHTSA complaint #719406, filed 2000-02

Electrical system: “Problems with the sliding door, headlamp fell off, automatic locks/window and etc. The consumer believed the vehicle has a coolant leak. The fuel modulator and spark plugs were replaced.”
