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.

report

From owner reports, verbatim

I AM A MAINTENANCE MECHANIC FOR A LARGE TRUCKING FIRM. ON 4 OCT 2011, I CHECKED THE TORQUE ON THE 5TH WHEEL BOLTS OF UNIT 11054 BECAUSE I COULD SEE THAT THE 5TH WHEEL WAS SLIDING ON THE FRAME. THE BOLTS WERE DEFECTIVE - YIELDING PRIOR TO REACHING THE RECOMMENDED TORQUE OF 236 FT.LB. I ADJUSTED THE TORQUE WRENCH TO 200 FT.LB., ITS LOWEST SETTING, AND COULD NOT GET ANY OF THE BOLTS TO HOLD. I REPLACED ALL TEN BOLTS WITH 5/8" GRADE 8 HARDWARE INSTEAD OF THE FACTORY 16MM 10.9 METRIC BECAUSE THAT WAS ALL WE HAD AVAILABLE. THERE WAS NO INTERFERENCE BETWEEN THE 5TH WHEEL BOLTS AND THE HUCK RIVETS ON THE FRAME RAIL. THE BOLTS WERE WEAK. *TR

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
