The 2014 Mercedes-Benz ML350 has 4 recalls, the most serious involving an oil leak near the front suspension that can reach an ignition source and start a fire, alongside a fuel pump control unit that water can damage and cause the engine to stall while driving.
The stall risk comes from water pooling in the spare tire wheel well and degrading the fuel pump control unit, cutting engine power without warning while the vehicle is in motion. On the safety systems side, a software fault in the airbag control module can prevent airbags from deploying correctly in a crash, leaving occupants without that protection when they need it most. There is also a software issue affecting the emergency call system, where an incorrect date and time can cause the system to relay a wrong vehicle location to emergency responders, potentially delaying help from reaching the scene after an accident.
