2006 Mercedes-Benz M-Class ML350 4dr SUV AWD (3.5L 6cyl 7A)
Picked up my ML 350 Nov 2005. After driving 25 miles the "Check coolant level" message came up. I took it to the dealer who checked the hoses. 75 miles later the same message reappeared. The dealer said to bring it in. They found a leak in the head gasket, and the car had only 650 miles on the odometer. But the most frustrating thing is I took it in on Jan 19th. It is now March 2 and the car is still in the shop!According to the dealer all parts have to come from Germany. I am at my wits end. For a $50,000 car this is totally unacceptable! This is Mercedes reliabilty for you!
