What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall involves a structural vehicle defect (fifth wheel bolts) that could result in trailer separation and a crash, meeting the criteria for a Severe rating.

Plain-English summary

Mack Trucks, Inc. is recalling certain model year 2008-2011 CHU and CXU heavy trucks manufactured from January 2008 through July 2010. The recall covers 808 vehicles, including specific Pinnacle models from 2011.

The defect involves potential interference with the bolts used to secure the fifth wheel to the frame. This interference can prevent the bolts from being torqued to the required specification. If the bolts fail, the fifth wheel could come loose, causing the trailer to separate from the tractor and increasing the risk of a crash.

Dealers will inspect and replace the bolts as required free of charge. The safety recall began on May 30, 2011. Owners may contact Mack Trucks at 1-800-866-1177 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
