The 2013 Mercedes-Benz ML550 has 3 recalls, the most serious being a water intrusion issue in the spare tire well that can damage the fuel pump control unit and cause the engine to stall without warning while driving.
A separate front suspension issue involves leaking oil that can reach an ignition source and start a fire. On the electronics side, a software fault in the emergency call system can cause it to report an incorrect date, time, and vehicle location when triggered, which may send emergency responders to the wrong place and delay their arrival.
