The 7-speed automatic transmissions has problems with internal component failure that cause rough shifting going up from first to second gear and going down from
third to second or second to first gear. Dealer says valve body replacement is needed. The cost: $2731.70. That's highway robbery!! Cant't afford it.
Hard shifts,after complete stop the suv will rev up and will not move then you have to shut off enginge restart and problem goes away I was told that valve body needs replacing and software upgrade Why this year ml350 has not been recalled
When going up a hill, it feels like I'm not going to make it because it's very slow until I take my foot off gas and then on again it'll pick up.
I had complained for over 30,000 miles of rough shifting, then was told it would be 1700 to fix, I went to an aftermarket repair and had it done for 1100, again, why hasn't it been recalled.
I've only had my car from approximately for 2 weeks(used 2007). The first time I took the car for a test drive it was smooth riding. After signing the paper work and started home the car would not come out of 2nd gear. I turned around and went right back to the dealer. The sales person got in the car and hit a couple of buttons and the car was fine, except for a noise sounding as if it was coming from the power steering area. Brought the car back to the dealer the next day the owner acted like he didn't here anything; the car is in the shop at (dealer) Mercedes. It's been for three days already.
I think this should have been consider a Mercedes RECALL!!!!!!!!!!!!!!!
DOES ANYONE ELSE FEEL THE SAME!!!!!!!!!!!!!!!!!!!!!!!
I was told my Valve Body needed to be replaced, but now there are a host of other resolutions. I'm still a little confused on the entire problem but the bill was reduced considerably once I complained about this systematic problem with Mercedes.
PROBLEM WITH SHIFTING, WONT GO OVER 20MPH. SHAKES REALLY BAD. JUMPS OUT OF GEAR. HAVE TO TURN VEHICLE OFF, THEN ON AGAIN, AND IT RIDES FINE, UNTIL IT HAPPENS AGAIN. NOW IT WONT GO OVER 20MPH..
I bought my car approximately 16 months ago. I was driving at approximately 35 mph when i felt my engine begin ti idle. I pressed the gas and the car began to resume speed. I decided to pull over and check out the problem. I was satisfied that there was nothing wrong. Climbed back into my vehicle put it in drive and the car would not move. I tried reverse and the car would move budge. I have it in the shop now but I haven't been told the damages.
as listed coarse gear changes in low gears and sometimes leaps forward a bit from start off especially on steep uphills
Rough shifting above 40 miles/hour speed and during downshifting. Car is not changing gears above 40 miles and will not run more than 60 miles/hour.
Rough shifting (especially when cold) from 1 to 2 and now started from 2 to 3 also. When slowing down, the same problem: 2 to 1 rough shifting. Otherwise, runs and feels great.
