Replace Rear Axle
This is to notify you of the STOP DRIVE Recall Campaign Launch to replace the rear axle on 278 Model Year (“MY”) 2022 AMG G63 4×4 squared (463 platform) vehicles. The recall campaign will be visible on the www.NHTSA.gov website and may generate questions from customers.
Affected VINs will be flagged in VMI as “OPEN” on October 13, 2023.
Issue
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2022 AMG G63 4×4 squared (463 platform) vehicles, the rear axle differential housing might not meet the strength requirements. Cracks in the rear axle differential housing might occur during vehicle operation, which may lead to differential oil leaking onto the roadway. In this case, a risk of a crash for following vehicle traffic may be increased.
Further, fracturing of the housing cannot be ruled out and could lead to an interruption of the power transmission on the rear axle, in which a loss of wheel guidance and a loss of propulsion without warning cannot be ruled out. In this case, the risk of a crash or injury could be increased.
What We’re Doing
MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will replace the rear axle on the affected vehicles.
Parts
The remedy is available and can be performed.
Given this notice, it is a violation of Federal law for a dealer to sell or lease any new vehicles in dealer inventory covered by this notification until the vehicle has been repaired. Once the remedy is available, the vehicles will be flagged as “OPEN” and Work Instructions will be available in NetStar VMI and Xentry Portal. Once the repair is complete the vehicle may be sold or leased.
Until the inspection/remedy is completed, affected vehicle owners are instructed by the MBUSA Customer Assistance Center (CAC) to stop driving their vehicles and will assist to make arrangements with their preferred authorized Mercedes-Benz dealer to have the vehicle towed for inspection.

Chronology :
On December 5, 2022, MBAG launched initial investigations based on an internal test showing a fracture of the rear axle differential housing. No third party damages or personal injuries were reported. Immediately, analyses of the failure mechanism and root cause were started together with the supplier. Subsequently, first cases from the field were reported outside of the US. However, still no third party damages or personal injuries were reported.
In mid December, the analysis indicated a stress induced fracture of the housing during operation of the vehicle. This root cause of the fracture is currently still under analysis.
In parallel, possible consequences for the vehicles in the field were analyzed together with the determination of the potentially affected vehicles.
On December 16, 2022, MBAG determined that a potential safety risk cannot be ruled out and decided to conduct a recall.
MBUSA contacted the agency on December 16, 2022 to inform NHTSA of the safety recall, stop drive instructions, and that communications with owners would start as soon as possible.
MBAG confirms there are no warranty claims, field or service reports, and other information (such as the numbers of deaths and/or injuries) related to this defect in the USA.

Cracks in the rear axle differential housing might occur during vehicle operation, which may lead to differential oil leaking onto the roadway. In this case, a risk of a crash for following vehicle traffic may be increased. Further, fracturing of the housing cannot be ruled out and could lead to an interruption of the power transmission on the rear axle, in which a loss of wheel guidance and a loss of propulsion without warning cannot be ruled out. In this case, the risk of a crash or injury could be increased. An authorized Mercedes-Benz dealer will replace the rear axle on the affected vehicles. Prior to performing this Campaign: VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. Always check for any other open campaigns, and perform accordingly. Please review the entire Campaign bulletin and follow the repair procedure exactly as described.

The recall population was determined through production records. Vehicles outside of the recall have the rear axle differential housing that meet the strength requirements. Production Dates : JUL 13, 2022 – OCT 21, 2022 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2022 AMG G-Class (463 platform) with the special edition 4×42, the rear axle differential housing might not meet the strength requirements. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Cracks in the rear axle differential housing might occur during vehicle operation, which may lead to differential oil leaking onto the roadway. In this case a risk of a crash for following vehicle traffic may be increased. Further, fracturing of the housing cannot be ruled out and could lead to an interruption of the power transmission on the rear axle, in which a loss of wheel guidance and a loss of propulsion without warning cannot be ruled out. In this case, the risk of a crash or injury could be increased. Description of the Cause : Due to a potential process deviation at a supplier, the strength requirements of the rear axle differential housing might not be met. Currently in analysis. Part 573 Safety Recall Report 22V-937 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Identification of Any Warning that can Occur : The driver will not receive a warning due to the nature of the failure mechanism. Involved Components : Component Name 1 : rear axle Component Description : rear axle Component Part Number : A4633503701, A4633505601 Supplier Identification : Component Manufacturer Name : Oberaigner Powertrain GmbH Address : 4155 Nebelber Daimlerstraße 1 Foreign States Country : Austria Chronology : On December 5, 2022, MBAG launched initial investigations based on an internal test showing a fracture of the rear axle differential housing. No third party damages or personal injuries were reported. Immediately, analyses of the failure mechanism and root cause were started together with the supplier. Subsequently, first cases from the field were reported outside of the US. However, still no third party damages or personal injuries were reported. In mid December, the analysis indicated a stress induced fracture of the housing during operation of the vehicle. This root cause of the fracture is currently still under analysis. In parallel, possible consequences for the vehicles in the field were analyzed together with the determination of the potentially affected vehicles. On December 16, 2022, MBAG determined that a potential safety risk cannot be ruled out and decided to conduct a recall. MBUSA contacted the agency on December 16, 2022 to inform NHTSA of the safety recall, stop drive instructions, and that communications with owners would start as soon as possible. MBAG confirms there are no warranty claims, field or service reports, and other information (such as the numbers of deaths and/or injuries) related to this defect in the USA. Part 573 Safety Recall Report 22V-937 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : The remedy is currently under analysis. An authorized Mercedes-Benz dealer will check and, if necessary, replace the rear axle of the affected vehicles. Until the inspection/remedy is completed, customers will be instructed by the MBUSA Customer Assistance Center (CAC) not to drive their vehicle and will assist to make arrangements with their authorized Mercedes- Benz dealer to have the vehicle towed for inspection. Towing and loaner vehicles, where available, will be offered at no cost to the customer. 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.
