New recall coming soon for 26k vehicles. Could be the entire 2019-2022 production run. The 4x4 model is not affected.
Issue:
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2019-2022 G-Class (463 platform) vehicles, the front axle wiring harness might contact an auxiliary oil cooler and chafe. This could potentially damage the wiring harness over time. As a result, impairment of ABS and ESP functionality cannot be ruled out, which could potentially increase the risk of a crash. If the failure occurs, the driver would be made aware through an indicator lamp or warning message in the instrument cluster.
What We’re Doing:
MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealership will inspect the front axle wiring harness on the affected vehicles and replace it, if necessary. After inspection if the wiring harness is not replaced a protective sleeve will be installed.
Chronology:
In February 2022, Mercedes-Benz AG began a review of isolated field reports by owners of G-Class vehicles, who stated they had observed an ABS and ESP indicator lamp in the instrument cluster. No related crashes, third-party damages, or personal injuries were reported. MBAG requested parts from the affected vehicles for further analysis.
From March through May 2022, based on its investigation and analysis of the parts collected from the field, MBAG determined that, in the analyzed cases, the front axle wiring harness had come into contact and chafed on an auxiliary oil cooler causing damage to the wiring harness.
In April 2022, to guard against such potential chafing, MBAG made a production adjustment, installing a protective sleeve on the potentially affected section of the wiring harness of all G-Class vehicles.
In parallel MBAG carried out systematic analysis of potentially affected signal wires for each possible wiring harness configuration. As part of the analyses, all functions of corresponding signal wires of the various wiring harness variants were checked and examined with regard to safety-relevant effects. In the course of this analysis MBAG determined that safety relevant consequences are limited to the potential impairment of the ABS and ESP brake system functionality. These investigations were completed by the end of 2022.
On February 10, 2023, MBAG determined that a potential safety risk could not be ruled out and decided to conduct a recall.
MBAG is currently aware of 12 warranty claims potentially related to this case between January 01, 2020 and July 6, 2021 and no other field reports regarding this defect in the US. MBAG is not aware of any reported crashes or personal injury in connection with this issue.
So this actually happened to me yesterday: Driving and suddenly began getting all these error codes: ABS failure, lane departure, etc. Then the car just shut off. It was extremely unnerving, especially for such an expensive car with little miles . We have 2 G wagons and now they both have experienced this. The first time I thought it was a one off situation but it appears it is an ongoing issue with these model years. Very scary. Does anyone know if the dealers actually have the solution yet or do we have to wait?
Oh and to think I got rid of our range rovers for more reliable cars, I am starting to think a joke is being played on us because we have taken our cars more to the dealership than we did with the RRs. We have had a roof leak, engine light thermometer replacement, squealing randomly when driving, and falling sensors. We also noticed that along the door sills, the G decals are falling off and appear glued on.

Take it to the dealer and they can inspect and replace the front axle harness now if it is the culprit.

Currently in South Fl, all the Mercedes-Benz dealerships are owned & operated by AutoNation. I’ve done that , even after the recent announcement! They had my car for over a week & nothing got done! On top of that, they are telling me that the fix it’s out yet! There is nothing that can be done!! Listen they aren’t the most pleasant people to deal with! I don’t have it in me to pick them apart because it will not change anything! I’d rather not send my card to them, so I don’t get it back with more issues!

Yes I have had one of my Mercedes serviced in the Miami area once and swore never again. Worst service experience I have ever encountered in my life even compared to Chevy and Buick and VW dealerships. They are absolutely clueless down there in my opinion.
I go to Mercedes Benz of Coral Gables for service and they are terrific. They are not part of Auto Nation and are independently owned. I highly recommend Francisco Esteves as a service advisor. He services my 2021 G63 and is exceptional.

The car shut itself off while you were driving? Can’t be!
FWIW, in 3.5 years and ~50,000km I’ve had no such issues at all with my 2019.
Active brake assist inoperative? If it happens rarely and it goes away after you start and stop the car, it’s normal. Your dealer won’t be able to fix it. Waste of time.

Yes, Active Brake Assist Inoperative and Active Distance Assist Inoperative. Happens on occasion. It's considered to be normal? Strange...

It‘s just one of those things that will be very difficult to solve by a dealer. It happens about once or maybe twice a year (every 5000-10000km perhaps). Happens on my AMG GTC as well.
If it doesn’t persist after you shut down and restart, I wouldn’t worry about it.
I have the same error occasionally, the dealer says, bring it in when I see the error, but it’s not always convenient. If I shut the vehicle off and start it back up, it goes away. I’ve brought it into the dealership before and they’ve reset, and re-calibrated everything, but I still continue to see the error message occasionally. The front axle wiring harness recall is supposed to be available April 6.
I've had that issue occur in both my G63's. As Surge says it's always fixed at the next restart. I don't even let it bother me now other than a roll of the eyes when it happens.
