The 2014 Mercedes GL350 BlueTec faces issues such as overheating and stalling due to various engine problems. These may include a spark plug becoming dislodged, a loose gasket needing prompt tightening, and potential oil leaks requiring immediate attention. A critical concern is the engine overheating, which could result in fires and even the vehicle exploding. Additionally, there might be excessive oil consumption, necessitating more frequent oil changes than usual. It is recommended to change the coolant every 60,000 miles, replace the air filter every 15,000 to 30,000 miles, and swap out the spark plugs every 100,000 miles, unless using a copper spark plug, which should be replaced every 30,000 miles.
