Mercedes-Benz’s most rugged could be brought to a stop by nothing more than itself, and that has led to the brand’s latest recall. The fault involves wiring that could chafe, creating problems for the ABS and the electronic stability control systems.
The automaker must repair a total of 26,116 G-Classes because of the problem, which it first became aware of in February 2022, when it received what it describes as isolated field reports from G-Class owners who started noticing that the ABS and ESP warning lights were lighting up on their vehicles.
The automaker investigated the issue through May and found that the front axle wiring harness could come into contact with the auxiliary oil cooler, causing damage to it. By April, it had introduced a new protective sleeve to the G-Classes that were being built at its factory to protect them from experiencing the issue.
By February 2023, meanwhile, it had determined that the chafing wires pose a possible safety risk to owners of the 2019-2021 G550 and the 2019-2021 AMG G63, specifically, those built between June 22, 2018, and December 23, 2021.
So far, Mercedes says it has received 12 warranty claims related to this issue. Fortunately, if the problem presents itself, owners will be made aware of an issue thanks to those ABS and ESP warning lights. Perhaps as a result of that, the automaker says it is not aware of any crashes or injuries related to this fault.
To prevent them from happening, though, the automaker has launched a recall campaign and will get in touch with owners starting on April 18. Mercedes will ask the customer to return their 2019-2021 G550s and AMG G63s to a nearby dealer, where a protective sleeve will be installed over the front axle wiring harness to protect it from damage.
