I have a 2018 Mercedes Benz c63 amg which I purchased new in 2018. I have only 61,230 miles yesterday 11/10/2025 it started making a loud noise coming from the right rear. I drove to the Mercedes dealership in Belmont,Ca the technician mechanic told me that the rear differential was bad and need to be replace. Cost $7,000. I don't understand only 61,230 miles why did it go out so soon I always had the maintenance done. My warranty has expired. I did some research and found that there was a recall for 2018 Mercedes Benz c63 amg related to the rear differential. The recall was issued due to potential issues with the rear differential that could lead to a loss power to the rear wheels, increasing the risk of a crash. Owners were advised to contact their local dealerships for repairs or replacements as necessary.
NHTSA complaint 11700378The contact owns a 2018 Mercedes-Benz AMG C63.

The vehicle was taken to a local dealer where it was diagnosed that the fuel tank door failure was a known manufacturing failure. The fuel tank door was replaced by the dealer on several occasions but the failure recurred. The vehicle was temporarily repaired with wiring to prevent the fuel tank door from closing. The manufacturer was made aware of the failure. The failure mileage was approximately 20,000.
