Our assessment, not the agency’s: severity 4/5 (Severe).
The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.
Our severity reasoning: The recall involves a structural vehicle defect in the steering system that can cause a complete loss of steering, which aligns with the rubric criteria for a Severe (4) rating.
Plain-English summary
Mack Trucks, Inc. is recalling certain 2016 Pinnacle CHU and CXU diesel trucks equipped with specific Dana steer axles. The recall involves 439 vehicles where the castellated nut and cotter pin on the steer axles may not have been properly torqued. This defect allows the tie rod to loosen within the steer axle.
If the tie rod loosens, it may disconnect from the steering knuckle, resulting in a complete loss of steering and increasing the risk of a crash. The recall began on October 17, 2017.
Mack will notify owners, and dealers will inspect the torque of the castellated nut and tie rod, tightening it as necessary. If the tie rod stud and knuckle cannot be sufficiently torqued, the dealer will replace the knuckle and tie rod end assembly free of charge. Owners may contact Mack customer service at 1-800-866-1177 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
