general problems of the 2012 Mercedes Benz ML350

Two problems related to power train have been reported for the 2012 Mercedes Benz ML350. The most recently reported issues are listed below.

1 Power Train problem

Failure Date: 03/29/2019

This car's transmission went out at 70,000 miles (2015), which is way too early. Driving when the transmission began to act up was very dangerous and potentially as it lost power could have caused collision. I replaced transmission for $14,000 and then the transmission went out for a second time (2019). Causing the same safety concerns as it lost power. This time I was not stupid enough to fix it and will not be buying a mercedes ever again.

2 Power Train problem

Failure Date: 11/19/2015

Oil was leaking from the engine which was the result of a faulty part that mercedes has subsequently replaced with a new re-engineered part. The dealer indicated that the issue is systemic with all blue-tec m and g class vehicles which mercedes will not cover the charge for. The repair requires that the engine be removed from the car because that it is the only way the part ($30) can be replaced. The resulting repair cost over $1900 in labor. We noticed the leak because there was oil drips in our garage. The service technician at the dealership noted that we had lost about a third of our oil and that the oil was covering the engine and it was also noted that the oil could have caused a fire if the part was not immediately replaced.
