The 2017 Mercedes-Benz G Class has two recalls, the more serious being a reverse gear speed limiter that may not function correctly, allowing the vehicle to travel faster than intended in reverse and potentially roll over if the driver steers sharply.
The second recall involves the brake booster vacuum hose, where the inner wall of the hose can delaminate and shed material internally. If this occurs, brake booster performance can be reduced, meaning the brakes require more pedal force than expected and stopping distances can increase.
At a glance
What can fail
The reverse gear speed limiter may fail to restrict reverse speed to 25 km/h. If you steer sharply while reversing faster than this, the vehicle could become unstable and roll over.
What the fix does
Dealers will reprogram the engine control unit to properly limit reverse speed to 25 km/h.

At a glance
What can fail
The brake booster vacuum hose may have an internal defect that causes its inner wall to separate. This reduces vacuum supply to the brake booster, requiring harder brake pedal pressure and longer stopping distances.
What the fix does
Dealers will inspect the vacuum hose and replace it if needed.
