What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 5 complaints with NHTSA since 2015. 4 of them name Forward Collision Avoidance, Wheels — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
I received a recall notice for this vehicle stating that the wheels may not be safely attached and could come off back in early May. It's been over a month and Mercedes has no solution for the recall at this time. I'm looking to get help with not having to pay my lease since I cannot use the car safely

Mercedes G63 with approx. 3500 miles will suddenly enter into collision avoidance mode. Specifically, the seatbelts will tighten up and the brakes will fully engage to stop the vehicle. In all cases, there was no risk of collision and the system engages with false positive alerts.

While driving at around 35mph, the recently-installed rear left snow tire on the car popped off and was propelled several hundred feet down the road. Upon reviewing the recall information of the car, it seems likely the indicent was caused by defective wheel bolts

Common questions

Is the LI42.45-P-079232 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Mercedes-Benz warranty extension on file lists the ones Mercedes-Benz has filed.
Which vehicles does LI42.45-P-079232 cover?
The manufacturer filed it against 1 model year: 2025 Mercedes-Benz G-Class. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
