The 2016 Mercedes-Benz GL550 has 4 recalls, the most serious involving a front suspension oil leak that can reach an ignition source and start a fire.
Water can enter the electric power steering control unit and shut down power steering assist, leaving the driver with significantly heavier steering than expected and a higher risk of losing control. On the occupant safety side, the front passenger seat sensor can misclassify a passenger, causing the front passenger airbag to deploy incorrectly or not at all in a crash, which raises the injury risk for anyone riding in that seat. There is also a software fault in the emergency call system where an incorrect date and time can cause the system to report the wrong vehicle location to emergency responders, potentially delaying their arrival after a crash.
