The 2015 Mercedes-Benz GL450 has 3 recalls, the most serious involving axle bolts on the front and rear drive axles that may not have been properly secured, which can cause instability and raise the risk of a crash.
A separate suspension recall involves a front suspension component that leaks oil, which can reach an ignition source and start a fire. On the electronics side, a software fault in the emergency call system can cause it to report an incorrect date, time, and vehicle location when contacting emergency services after a crash, potentially delaying the response.
