Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Reached for a fallen object between the driver and middle front seat and there is a razor sharp piece that took a large chunk out of the hand which caused heavy bleeding and medical supplies to stop. The vehicle was stopped and just tried to retrieve fallen object between the seats. The incredibly sharp parts need to be cut or removed from this and other similar vehicles or covered with something. It was bare metal exposed out with sharp edges that cut the right hand so badly.”
