Problem overview

Some Mercedes-Benz ML350 owners report experiencing engine oil leaks, which can result in oil puddles under the vehicle or a burning smell due to leaks in gaskets or seals. Additionally, complaints about engine issues have been noted, particularly around an average of 49,563 miles, which may indicate potential engine failure. Some owners also report a louder engine than normal, potentially caused by a dirty or failing sensor, leading to increased strain on the engine. Furthermore, certain models like the ML63 are known to have significant problems, including melted motor mounts and stretched timing chains, which can be costly to repair. A commonly reported issue among ML350 owners is a faulty camshaft adjuster solenoid, especially in model years 2006, 2007, 2008, and 2012, which affects the variable valve timing system. Addressing these issues promptly is essential to prevent further complications and ensure the vehicle's longevity.
