The 1998-2000 trucks had (have) many problematic areas..later trucks are much better.. The biggest problem is the lack of recommended service & people believing that they can go EVEN farther than that.

Well serviced 2001 & later ML aren't money pits but following 15,000 service intervals will cause them to be $$$$ pits.

The most common problems are lack of air filter changes resulting in Mass Air Flow sensor failure & that causes the Catalytic converters to fail prematurely.
