NHTSA recall 22V194000
Power Train, Suspension · Mercedes-Benz USA, LLC
Details
What's wrong: The sub frame weld for the thrust arm on the rear axle carrier may have been improperly welded, causing the thrust arm to break and detach.
Why it matters: A detached thrust arm can cause a sudden loss of vehicle control, or cause the vehicle to pull to one side during emergency braking, increasing the risk of a crash.
The fix: Owners are advised not to drive their vehicles until the remedy has been performed. Dealers will inspect the sub frame weld on the rear axle carrier and replace the rear axle carrier as necessary, free of charge. Owner notification letters were mailed April 8, 2022.
