2021 Mercedes-Benz Amg G63 recalls & complaints

1. Seat belts

What's wrong, in plain English: Seat belts may not hold you in a crash. The rear seat belt automatic locking retractors may deactivate early, which can prevent the child restraint system from securing properly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."

What could happen: An unsecured child restraint system can increase the risk of injury during a crash.

The fix: Dealers will inspect, and replace as necessary, the rear seat belt assemblies, free of charge. Owners notified of the voluntary recall campaign by an interim letter on August 13, 2021. A final letter was mailed on September 24, 2021. Owners may contact MBUSA customer service at 1-800-367-6372.

What to do

1. Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2021 AMG G63.
2. Book a repair at any authorized Mercedes-Benz dealer. Quote NHTSA campaign 21V483000.
3. The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
4. Manufacturer hotline: 1-800-367-6372.
5. Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

2. Latches / locks

What's wrong, in plain English: Doors, hood or trunk may open unexpectedly. Components within the door latch may prevent the rear doors from latching or opening properly.

What could happen: The rear door may appear closed even when the latch is not fully engaged, allowing the door to open while driving and increasing the risk of injury or a crash. Damaged latch components may prevent the rear door from being opened while inside the vehicle, increasing the risk of injury.

The fix: Dealers will replace the rear door latches, free of charge. Owner notification letters were mailed July 9, 2021. Owners may contact MBUSA customer service at 1-800-367-6372. Note: Vehicles repaired prior to this recall must return to dealers to have the remedy performed. MBUSA's numbers for this recall are 2021060…
