Belt tensioner was replaced. Flex disc on drive axle replaced. Power steering unit leaks, but still works well. Electrical system sometimes acts up. (wipers and radio turn on by them selves with the car off) Seems to shift harder than other models.
Lack of power.
Very comfortable for a tall person.
Handles well.
Hard to find parts.
The southern sun has worn out the paint on the hood, roof and trunk only.
The funny thing with 40MPG 190D's is that when you manually shift the Automatic transmission from #2 to Drive at about 35MPH give or take, the car is a HECK of a lot faster than in just putting it in plain Drive no matter what, weird huh! It's been like that with 3 different 190D's.
TIP: To those who drive 190D's and other diesel vehicles, it's OK to put the diesel petal to the floor all the time because it won't hurt the engine (it's a diesel!), as long as the engine is warmed up of course. My 190D has about 500,000 miles on the engine.
