What can fail
The right-side rear door latch may have faulty components that prevent the rear doors from latching or opening properly.
What the fix does
The 2021 Mercedes-Benz G 550 has 7 recalls, the most serious involving a fuel pump that can shut down without warning, cutting engine power while driving and raising the risk of a crash.
Two recalls address the rear door latches: components inside the latch can fail to fully engage, leaving the door appearing closed while it can swing open during a drive. One of these recalls covers vehicles where a prior repair attempt did not fully resolve the issue. On the electrical side, the front axle wiring harness can rub against an oil cooler and wear through its insulation, knocking out anti-lock brakes and electronic stability control at the same time.
Occupant restraint issues account for two more recalls. The seatbelt pretensioners and airbags on certain vehicles may not perform correctly in a crash, and the rear seatbelt retractors can deactivate too early to properly lock a child safety seat in place. Rounding out the list, the automatic emergency call system can become disabled, meaning the vehicle may be unable to contact emergency services after a collision.
