Example complaints

Fuel system: “We (elmore sims) are the owners of a 2004 Cadillac deville since may 2007. We have owned various models of cadillacs for more than ten years, and have not had any major problems. The name Cadillac's denotes quality. However, our latest purchase with this three (3) year old vehicle in the past few months, has caused us great repairs and expenses and loss of confidence in the name Cadillac's. The first repair was with the fan motor for the air conditioning, which cost $240. The next major repair was the fuel pump, which cost $600. …”

NHTSA complaint #10209581, filed 2007-11

Air bags: “On 12/5/04 I parked our new (561 miles) 2004 Cadillac deville at the covered west palm beach airport parking lot. I left on business and returned to the car at 7:30 pm on thursday, 12/9/04. I got into the driver's side, put the key in the ignition and started the car. The two front and passenger side airbags airbags deployed! The driver bag raked up the inside of my right forearm (which was still holding the key in the ignition) and then hit me in the left side of my face. …”
