Official manufacturer communication context for 2019 Mercedes-benz Amg C43, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz, has determined that the active engine mounts in certain C-Class (model series 205), E-Class (model series 213), GLC (model series 253), and AMG GT (model series 290) vehicles cannot be energized after a failure of the acceleration sensors. As a result, noises from the rear axle differential would be noticeable. This is why a software update of the AMG drive unit control unit must be performed in the affected vehicles. The work required for this purpose can be found in the attached work description.
