Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have had to replace my condensing unit two different times. Once at 75,000 miles, which was covered by my extended warranty that I purchased, not by GM, and the other broke at 107,000 miles in the exact same spot, which I had to pay for. This is a joke! I have also had to replace my oil cooling lines two different times, which were also not covered under warranty.”
