The 2017 Mercedes-Benz G550 has 3 recalls, the most serious being a malfunction in the electronic stability program that can prevent the engine from cutting power when the adaptive cruise control system is engaged, forcing the driver to shift to neutral or brake harder to slow the vehicle.
The second recall involves the vacuum hose that assists the brake booster. If that hose collapses, the power assist to the brakes is reduced and the pedal requires noticeably more force to slow the vehicle, extending stopping distances. There is also a concern with the automatic emergency call system: if it malfunctions after a crash, it can transmit an incorrect location to emergency responders, delaying help from reaching the scene.
