The 2012 Mercedes-Benz ML350 has 3 recalls, the most serious being an oil leak near the front suspension that can reach an ignition source and start a fire.
Water pooling in the spare tire wheel well can damage the fuel pump control unit, causing the engine to stall without warning while driving and raising the risk of a crash. The third recall involves a software defect in the airbag control system that can prevent the airbags from deploying correctly in a crash, leaving occupants with less protection than intended. This last recall only affects ML350 4Matic models.
