The 2012 ML350 doesn't ride or drive like an E-Class (I've had two) but neither does anything else either. The ML350 is a great freeway car. It is roomy, comfortable, and drives like a dream. It has excellent seats and it is quiet inside. In a recent non-freeway trip of several hundred miles, my ML350 BlueTec averaged 30.9 mpg for the entire trip. That mileage will get the vehicle nearly 700 miles between fueling stops! This was my 4th Mercedes and 3rd diesel. Overall, it is, by far, the best car that I have ever owned.
My 2012 ML350 ,the car only has 50,560 miles ,more than 6 check in at the service department and today without the Mercedes Benz warranty in force (more than 50,000 miles)the comand system stop working,so by defect the back up camera is not working as well,no radio,no navigator and many more issues.The right side mirror is not folding (3rd time that do that)and I have problems with the power lifgate as well(stops in the middle of the opening). I don't remember a day not regreting for the ML350 purchase.Before this car I owned a Ford Edge that never went to a mechanic in the 3 years that I owned it. They didn't call me from the dealer yet,but for sure the bill will be gigantic.
Just to share my story. I purchased a ML350 SUV in 2013. Nice looking vehicle and I was ready to enjoy.
Well, here is what happened. First, I had a problem with the drivers seat. They fixed that after two tries. I did hate to complain, but the vehicle cost a lot of money.
Second problem. I have a noise somewhere near the steering wheel and tires. It sound like a screw was loose and the vehicle could come apart, or at least the front part. I took the vehicle in, the man said it was ok. NO. NO. I went back a week later and they kept it for 12 days. They say it was a coupling near the steering whell and the bushing. Well, they fixed that too. Still, the problem is not completely fixed.
My 2012 ML350 is a major disappointment with numerous technological issues. it has been to the dealer for repairs more than any car i have ever owned. I am again driving a loaner for the 8th time in a year and a half. I have recorded videos of the malfunctions, dealer has duplicated the issues on occasion, and it is still not fixed. I contacted MBUSA for assistance and resolution and they did nothing except say 'take it to the dealer'. I cannot believe that mercedes would have such poor response and pathetic customer service. After years of contemplating purchasing a luxury vehicle I am hugely disappointed that my first experience is so negative. I should have the reliability I paid for.
The vehicle has a malfunctioning command system; malfunctioning lift gate; drives rough and stalls out from time to time, Bluetooth malfunctions. Just countless issues that have been without repair. It's embarrassing to drive a Mercedes that you can't drive with confidence.
