Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“3 weeks ago all the warning lights went off. The vehicle is still under warranty. I brought it to the dealership. They denied the warranty because of mud that was caked on the undercarriage damaging the wiring and steering assembly. This truck was used on a dirt driveway that gets wet and muddy during the spring. That is what a truck is for. I believe there is a manufacturing defect that caused this problem.”
