What's wrong?
The rear axle carrier on the 2019 Mercedes-Benz Sl 450, Sl 550, and AMG SL63 is the cast structure that helps hold the rear axle in position. One of its mounting points uses a bolt connection to keep that carrier secured to the body. That connection helps the rear suspension and driveline stay aligned while the vehicle is braking, accelerating, and turning.
On these vehicles, a supplier production deviation left voids inside a batch of cast parts. The concern is in the front left mounting point for the rear axle carrier. Over time, that hidden weakness can reduce the load capacity of the bolt connection. If the connection fails, the rear axle carrier no longer stays secured as designed, which affects how the vehicle handles.
The warning sign listed for owners is a knocking noise from the rear axle. Treat that noise as a reason to stop driving and call a Mercedes-Benz dealer for recall guidance.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the front-left mounting point of the rear axle carrier and checks the bolt connection for the defect covered by recall 19V768. The inspection is free under the recall. If the defect is found, MBUSA contacts the owner and offers to repurchase the vehicle. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, since the involved vehicles remain under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
