Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I purchased a 2015 BMW i8 (salvage title) from Parkline Motors. The vehicle history (Carfax) disclosed prior front/right damage, which I accepted. However, the dealership failed to disclose critical safety-related defects associated with that damage.
