Campaign No. 2018020010, March 2018

TO: ALL MERCEDES-BENZ CENTERS
SUBJECT: Model 463 Model Year 2017
Replace Brake Vacuum Line

 

Daimler AG (“DAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain G-Class vehicles (463 platform) the vacuum hose for the brake booster may not have been manufactured according to current production specification. Thus, the interior wall of the four layer brake booster hose might delaminate. This might lead to a constrained vacuum supply of the brake booster. Delamination of the vacuum hose may result in reduced vacuum supply to the brake booster leading to increased braking effort by the driver. Depending on the prevailing traffic conditions, this may increase the risk of a crash. An authorized Mercedes-Benz dealer will replace the brake booster vacuum lines on the affected vehicles.

Prior to performing this Recall Campaign:

  • Please check VMI to determine if the vehicle is involved in the Campaign and if it has been previously repaired.
  • Please review the entire Recall Campaign bulletin and follow the repair procedure exactly as described.
