Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was purchasing this used car from a dealer. They replaced the ignition assembly 3 times. The car would mysteriously shut off, the ignition assembly would not allow the key to be removed and multiple times this happened. I lost allot of money I put on the car as it became obvious they could not fix it and I had to let them take it back with no refund to me.........they said at the dealer that I was lucky that I didn't have a fire.”
