The 2014 Mercedes-Benz ML550 has 3 recalls, the most serious being a front suspension component that can leak oil onto a hot engine or exhaust surface and start a fire.
Water pooling in the spare tire wheel well can damage the fuel pump control module, causing the engine to stall without warning while driving. A stall at highway speed leaves the vehicle without power steering or power brakes until the driver can safely pull over, raising the risk of a crash. There is also a software fault in the emergency call system where the date and time stored in the system can drift from the actual values, causing the system to calculate and transmit an inaccurate vehicle location if it activates in a crash, which can delay emergency responders reaching the scene.
