Example complaints

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

“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. …”
