Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Every since I purchased my car on 5/7/03, I have been having hard starts--more than 24 times. In addition, when the car was less than a year old, another dealer told me all 4 rims were bent. I also had a racing issue occur 3 times on sat. 3/12. I have taken the car back to the dealer 3 times for the two intermittent problems. Recently, they fixed the hard start by replacing the battery but they charged me for it. They should not have charged me if this is what caused the hard starts since day one. I told them this but they said they didn't find the battery to be a problem then. …”
