Mack Trucks is recalling certain model year 2014 CXU and GU model vehicles manufactured May 10, 2013, through June 12, 2013.
The upper and lower steering shaft pinch bolts may have not been torqued to specification.

- Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
