Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When reviewing the vehicle for purchase I noticed the SRS light on. I brought it to the dealerships attention. They instructed me to bring it back in the morning after signing paperwork so they could fix it. After I brought it back they let me know that they didn't see any SRS lights and would not be servicing the vehicle. There has been multiple mechanical issues with the vehicle including but not limited to the transmission going out, break recalls, engine leaks and now I'm being informed that my passenger air bag is deactivated. I just want a safe vehicle.”
