Recall 19V586 affects 26,584 2018-2019 Mercedes-Benz C 300 and AMG C43 vehicles for an unsecured battery bracket. Repair is free at any franchised Mercedes-Benz dealer.
Mercedes-Benz is recalling 26,584 2018-2019 C 300 and AMG C43 sedans under recall 19V586 because the 12-volt battery mounting bracket is not properly secured. In a crash, the battery can shift and disconnect, cutting power to emergency call and hazard light functions, and the battery itself can detach into the roadway. Mercedes-Benz dealers will secure the bracket for free.

What's wrong?
The 12-volt battery in these 2018-2019 Mercedes-Benz C 300 and AMG C43 vehicles sits in a mounting bracket bolted to a base plate under the hood. The bracket holds the battery in place so the terminals stay connected to the wiring that powers the car's electrical systems, including safety features that activate during a crash.
On affected vehicles, a production deviation at the supplier left some bracket bolts tightened beyond specification. That extra torque can start cracks in the bracket material. Over time, normal driving loads and vibration spread those cracks until the bracket breaks. If the bracket fails during a crash, the battery can shift and disconnect from its terminals, cutting power to electrical systems at the moment they are needed.
The first sign for an owner is often a rattling or knocking noise from the engine compartment while driving. That sound is the bracket loosening and the battery moving against its mount.
Who's affected?

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.
What's the safety risk?
A loose battery can lose power to post-crash functions like emergency communication and hazard lights, and it can detach and become a road hazard for other drivers. Listen for rattling or knocking from the engine compartment while driving, and treat those sounds as a reason to schedule the repair soon. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2018-2019 Mercedes-Benz C 300 or AMG C43 is included in this recall.
- Contact your nearest franchised Mercedes-Benz dealer to schedule the battery-bracket replacement that re-secures the 12-volt battery.
- Bring the recall notice if Mercedes-Benz has mailed one. If not, reference recall number 19V586 when you call.
- Call Mercedes-Benz customer service at 1-800-367-6372 with questions about the repair or scheduling.
- Drive cautiously until the repair is complete, since a shifted battery can disconnect terminals in a crash and impair post-crash electrical functions.
What happens at the repair
At the dealer, a Mercedes-Benz technician replaces the 12-volt battery mounting bracket so the battery stays secured in place. Parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the existing new vehicle warranty, not through a separate reimbursement program, since all involved vehicles remain covered under that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork for the battery bracket.
