Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Car's brake system slammed on in light traffic with no nearby obstacles. Clear night, light traffic, road dry, moderate temperature. If there had been more traffic, or if the road had been slick, high probability of risk. Dealer has been notified, will not be able to pick up vehicle for a day or two. I did not see any warning lights, heard no warning sounds.”
