Defect

TMC will notify owners, and authorized Daimler Trucks service centers will inspect the caliper mounting bolts and tighten them to the proper specification, free of charge. The recall began September 4, 2018. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000159.
