What's recalled

Component: Service brakes

Daimler Trucks North America LLC (DTNA) is recalling certain 2017-2021 Freightliner Cascadia tractor trailers. The single brake modulator valve may be affected by chemical corrosion which can slow down the release timing and cause the brakes to pull to the affected side during automatic braking events.

The risk

Brakes that pull to one side during automatic braking events may cause a sudden change in vehicle direction, increasing the risk of a crash.

The remedy and its status

DTNA will notify owners, and dealers will replace the front left and right single brake modulator valves will be replaced and spacers added, free of charge. The recall began August 28, 2020. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-855.

Status: NHTSA lists Aug 28, 2020 as the owner-notification date for this campaign.

Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
