The 2017 Mercedes-Benz GLS450 has 8 recalls, the most serious involving a front suspension oil leak that can reach an ignition source and start a fire.
A door latch recall covers a condition where a door that appears locked may still swing open unexpectedly, raising the risk of injury to occupants. The front passenger airbag on certain vehicles may not deploy correctly in a crash, leaving the front passenger without full restraint protection. The center console latch can fail to hold during a crash, allowing loose objects inside to become projectiles in the cabin.
Four recalls address the vehicle's automatic emergency call system. Across different filings, the system can fail to connect to emergency services at all, dispatch responders to the wrong location, or relay an inaccurate position due to a software fault with the date and time clock. The practical result in each case is the same: if a crash occurs, emergency help may be delayed or misdirected.
