What's wrong?
The rear axle carrier on the 2022 Mercedes-Benz S 500 and S 580 is the structural frame that holds key rear suspension and axle parts in position. The thrust arm attaches to this carrier and helps keep the rear wheel aligned as the suspension moves. That connection depends on a correctly made subframe weld.
On the recalled vehicles, the weld for the thrust arm on the rear axle carrier was not made to Mercedes-Benz production specifications. The problem came from a production process deviation. If the weld does not hold, the thrust arm can break away from the carrier, which can lead to noise at the rear axle and an unstable driving feel.
There is no warning sign before failure. Mercedes-Benz reported that the driver does not receive an advance warning because of the way this weld failure occurs.
Who's affected?
The same rear axle carrier appears under both drive axle and suspension categories, which is why the component labels differ in the list.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific sedan.
What's the safety risk?
A detached thrust arm can cause a sudden loss of vehicle control or make the vehicle pull to one side during emergency braking, increasing crash risk. There is no warning sign before failure. Do not drive, even for short trips. Ask the dealer about towing if the vehicle needs to move. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2022 Mercedes-Benz S 500 or S 580 is included in this recall.
- Do not drive the vehicle until the rear-axle-carrier inspection and repair are complete.
- Arrange a tow if the vehicle has to be moved to the dealer; do not drive it there yourself.
- Contact a franchised Mercedes-Benz dealer to schedule the free rear subframe weld inspection and rear axle carrier replacement that addresses the thrust arm detachment risk.
- Bring the owner notice if you have it. Reference recall number 22V194 when you call.
What happens at the repair
Do not drive the vehicle until the recall repair is complete. At the dealer, a Mercedes-Benz technician inspects the sub frame weld for the thrust arm on the rear axle carrier. If the weld is affected, the technician replaces the rear axle carrier. Parts and labor are covered under the recall. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
