Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

TRUCK WAS SITTING UNATTENDED AND WIRING HARNESS SHORTED OUT AND BURNED ALL THE WIRING UNDER THE HOOD. AFTER ASKING AROUND THIS IS A COMMON PROBLEM WITH THE WIRING HARNESS AND I CAN'T BELIEVE THERE ISN'T A RECALL FOR THIS PROBLEM. IF A DRIVER IS ASLEEP IN THE SLEEPER AND THIS WERE TO HAPPEN THERE COULD BE A LOSS OF LIFE OR CRITICAL/SEVERE INJURY. *TR
