The 2018 Mercedes-Benz GLS 550 has 3 recalls, the most serious involving a brake defect that reduces stopping performance and raises the risk of a crash.
The door latch system also has a recall: a door that appears fully latched and locked may still open unexpectedly while driving, which could eject an occupant or allow someone to fall out. There is also a recall affecting the automatic crash notification system, known as eCall, which is designed to alert emergency services after a collision. If that system fails, responders may be sent to the wrong location, delaying medical help when it is needed most.
