Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“To date, I have had my vehicle repaired three times for the same malfunction. I worked with manufacturing and sales organizations and I have failed to receive substantiation beyond your organization's due diligence that my vehicle is safe for my family. These organizations have failed to diagnose the specific malfunction with my vehicle (electrical) and subsequently have been gutting my vehicle piece by piece devaluing it.”
