DAIMLER TRUCKS issued a recall on multiple vehicle models

On certain trucks, the quick release valve (QRV) cover may not have been welded correctly during manufacturing process and may become loose or separate from the valve body. If this occurs, air pressure may not be supplied to the front brakes during brake application. The rear brakes will continue to function. Reduction in braking efficiency could increase stopping distances, possibly resulting in a crash causing property damage and/or personal injury. Correction: Daimler authorized repair facilities will inspect and if necessary replace the quick release valve.
