The Floor Mats I received for my vehicle covered a portion of my accelerator pedal and would when up into the back above the pedal and to the right of it and would get caught and force my accelerator pedal to stay down. I told the company of their design flaw, and they said would not do anything about it. If I wanted to send it back it would cost more than the pads were worth. I paid $189.95. I got PayPal involved and if I paid the shipping cost to send them back they would rebate me the money that I paid. That's only if the mats are in perfect condition when they receive them. So it cost hours of BS and $60 so I get back at least $129. But with that said I felt you should know that they are selling and sending things not made for the cars they promise they will be for.

I recently had to replace the power steering pump, reseviour, and hose after loosing control while driving on the highway. Immediately after refilling with fluid all the contents ran right out. I do see that there was a recall for this problem in 2008, but I did not take ownership of this vehicle until 2/15. Is there any way possible for this problem to be fixed under the recall?

Random loss of power ' (the entire panel lights up) as the car suddenly and slowly powers off while taking off from a drop, driving, breaking, and turning, coming to a stop and on the highway. In the past 6 months we have spent more than 3800.00 for car repair on the ml 350. It shuts off more and more frequently. So much so we do not allow our daughter to drive unless I am there and now not even then until we have had it fixed for the 4th time (we thought) after crank shaft, spark plugs and now electrical work we are at a total loss. This issue is not isolated but mercedes benz has had other reports our and others ' not repair / or recalled but it seems major to our family ' as my only vehicle and other owner that have invested in this make.

Within the past 8 months I have taken my car to the dealership four times with the issue relating engine shut off and check engine light comes on. I was told the crankshaft needed to be replaced two times and as of today the problems remains. Mercedes benz has acknowledged this is problem in this vehicle but has not addressed it. I fear driving this vehicle with my children it shut off in the middle of the highway at one point and they haven't addrssed it. I've spent $4500 to repair and they cannot resolve the problem and I'm not certain they know how.

I was backing out of my garage, when I heard a noise coming from the left front engine. I immediately put the SUV back into the garage and parked it. I saw an oil leak where it had been parked. Since then, I have been driving my toyota, and left the mercedes parked in the garage. The large oil leak concerned me.I spoke to a mercedes mechanic and described what I had heard, and he said it was most likely a steering problem. I checked online and noticed there are recalls for the steering hose and clamp for ml 350 models years 2003 +. In which the steering wheel oil leaks out. I would like to know if the recall is still valid? Does the mercedes dealer still have to replace the hose and clamp? What if they say they don't have to repair or replace these parts, then what do I say or do?
