For a pretty serious reason.
Despite being one of the toughest off-roaders on planet Earth, the Mercedes-AMG G63 4×4² is facing a recall for something that could ruin its off-road clout: the rear axle transmission housing could break at a moment's notice. According to the manufacturer, 278 units of the high-performance off-roader are affected, all of which require the replacement of the entire rear axle. Until such time as this is done, MBUSA urgently advises owners to stop driving immediately.
The paperwork filed with the NHTSA notes that the issue could present itself as a mere oil leak but can develop into a serious crack that can eventually lead to a loss of propulsion. Combined with severe leakages, the risk of a crash is very high.
Due to the unpredictable nature of the issue, Mercedes-Benz has warned owners to stop driving their cars and make their way to the nearest dealership as soon as possible (at a very leisurely pace, of course).
Mercedes-Benz has launched an official investigation into the matter and analyzed the housing failure with the supplier but has yet to figure out the cause of the cracking. The company has said that loaner vehicles and towing services will be offered where available and at no additional cost to its customers. Mercedes-Benz is yet to receive any reports of third-party damages or injuries.
The Mercedes-AMG G63 4×4² uses specialized portal axles to add to its off-road ability, but as it turns out, these fancy axles have become a weak spot.
Dealers were notified of the recall on 17 December, and Mercedes-AMG G63 4×4² drivers that are unsure if they need to go to a dealer can simply call the NHTSA or their local Merc dealer for more info.
Mercedes has suffered a few major recalls in recent memory, including a recall of nearly 60k GLS SUVs for a faulty locking mechanism used for the third-row seat backs. Earlier in the year, the company had to recall over 235k models of all descriptions for a malfunction with its emergency call system. Mercedes-Benz has promised that the G-Class will only get better once it goes electric, and for its sake, we hope so.
