The 2017 Mercedes-Benz AMG GLS63 has 7 recalls, the most serious involving a front suspension oil leak that can ignite if it reaches a heat source, raising the risk of a vehicle fire.
Two recalls address occupant safety systems. The passenger seat sensor that determines whether the front passenger airbag should deploy can malfunction, potentially leaving the front passenger without airbag protection in a crash. There is also a concern with the electric power steering control unit: if water gets inside it, the power steering assist can cut out without warning, requiring significantly more physical effort to steer and raising the risk of losing control.
Two separate recalls affect the emergency call system. A software fault can cause the system's internal clock to report the wrong date and time, which can cause it to transmit an incorrect vehicle location to emergency responders. A separate issue can cause the eCall system to fail outright, again potentially sending responders to the wrong place after a crash.
On the latch and lock side, a door latch can appear fully locked but still allow the door to swing open unexpectedly, which is a concern especially at speed. The center console latch can also fail to hold closed in a crash, allowing anything stored inside to become a loose projectile in the cabin.
