There is a risk of thread damage. (Note WIS- AR.33-10-P-0100MFA) We recommend that you clean the thread on the body-in-white, before reuse, with compressed air and check for possible damage/chips. Before partially screwing in screws, the contact surface of the front axle carrier at the body-in-white and the matching of the hole patterns must be checked. The new screws are screwed in by hand into the thread with 3 to 4 thread turns before a manual tool (e.g. ratchet wrench) is used for tightening. Attach screws with the specified torque. The steering remains in the vehicle and must be tied up/secured against sagging. One transverse control arm is released at the wheel hub to remove the front axle carrier. The second transverse control arm must be tied up/secured against sagging. Primary Parts Information Qty.

FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Under specific environmental influences, corrosion of the integral carrier of the front axle might occur after several years. As a result, depending on the intensity and location of the corrosion, an impairment of the structural durability of the integral carrier as well as the connection to other components cannot be ruled out. In this case, vehicle steering might be affected which could potentially increase the risk of a crash.

In May 2020, MBAG received isolated reports from its internal corrosion endurance testing indicating that the corrosion protection on certain integral carrier components of front axles did not meet MBAG specifications. MBAG immediately launched an internal investigation into this issue. In parallel, over the next several months, MBAG reviewed its supplier’s production of the integral carrier component to ensure that the part was manufactured with corrosion protection that met required specifications. From July 2020 until May 2021, MBAG engaged in an extensive investigation to determine the range of potentially affected vehicles by retrieving parts from the field and testing them according to MBAG’s corrosion endurance testing procedures. For investigation, MBAG retrieved used parts obtained from vehicles in the field systematically in a way such that MBAG had representative samples from all relevant production periods to help MBAG define the production date range of potentially affected vehicles. In parallel and until November 2021, MBAG conducted extensive tests to assess the potential safety effects of corrosion of the integral carrier component. Among other things, integral carriers were prepared in the corrosion endurance testing facilities to simulate different progress of corrosion and were then thoroughly tested in vehicles. Although no defects were identified during the testing and no field complaints worldwide have been reported, MBAG determined on December 10, 2021 to initiate a recall out of an abundance of caution as a safety risk cannot be fully ruled out. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer, will check the integral carrier on the affected vehicles and replace it, if necessary. Pursuant to 49 C.F.R. § 577.11(e), MBUSA does not plan to provide notice about pre-notice reimbursement to owners since none of the involved vehicles would have been previously subject to the condition described and all remain covered under the new vehicle warranty How Remedy Component Differs Corrosion protection of the integral carrier according to specifications.

MBAG immediately launched an internal investigation into this issue. In parallel, over the next several months, MBAG reviewed its supplier’s production of the integral carrier component to ensure that the part was manufactured with corrosion protection that met required specifications. From July 2020 until May 2021, MBAG engaged in an extensive investigation to determine the range of potentially affected vehicles by retrieving parts from the field and testing them according to MBAG’s corrosion endurance testing procedures. For investigation, MBAG retrieved used parts obtained from vehicles in the field systematically in a way such that MBAG had representative samples from all relevant production periods to help MBAG define the production date range of potentially affected vehicles. In parallel and until November 2021, MBAG conducted extensive tests to assess the potential safety effects of corrosion of the integral carrier component. Among other things, integral carriers were prepared in the corrosion endurance testing facilities to simulate different progress of corrosion and were then thoroughly tested in vehicles. Although no defects were identified during the testing and no field complaints worldwide have been reported, MBAG determined on December 10, 2021 to initiate a recall out of an abundance of caution as a safety risk cannot be fully ruled out.
