What is wrong
Daimler Trucks North America LLC (DTNA) is recalling certain 2016-2020 Western Star 4900 and 5700 vehicles equipped with sleeper cab vent windows. Due to improper adhesive, the vent window may detach from the vehicle.
What can happen
If the vent window detaches while the vehicle is in motion, it can become a road hazard, increasing the risk of a crash.
The remedy
DTNA will notify owners, and dealers will replace the vent windows, free of charge. DTNA issued owners an interim notification on December 27, 2019. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-836.
