Remind Mercedes C-Class: ingress of water causes a short circuit

Mercedes is recalling 101,445 C-Class cars worldwide. Ingress of water can lead to short circuits and possible fire.

The Federal Motor Transport Authority (KBA), the National Highway Traffic Safety Administration (NHTSA) and car manufacturer Mercedes have launched a recall campaign for Class C. 101,445 vehicles are affected worldwide, 10,254 in Germany and 6,752 in the United States .

Mercedes-Benz AG has determined that on certain cars of the C-Class Saloon (BR 206) series, if water enters the trunk of the car, moisture can penetrate the signal acquisition and activation module. As a result, a short circuit can occur in the signal acquisition and control module (SAM). In addition, various malfunctions may occur due to a short circuit. Among other things, external lighting may malfunction at the rear of the vehicle, the rear seat backrests can be opened without a pusher and the reversing camera cannot be provided. Fire risk cannot be excluded.

This model is affected by recall in Germany:

  • Mercedes-Benz C-Class Sedan (BR 206) Production period October 2020 to June 2022 (10,254 vehicles)

This model is affected by recall in the US:

  • Mercedes-Benz C 300 From production period June 24, 2021 to May 13, 2022 (6,752 vehicles)

As a precaution, the Mercedes-Benz Service Establishment will modify a cap over the SAM system in affected vehicles to prevent possible ingress of water. A planned visit to the workshop for adjusting the cover over the air defense system in the trunk of the car will take about an hour.

The recall can be found at the KBA under reference number 012144 and manufacturer code 6391006, at NHTSA under case number 22V-678.
