  Worst car Ive owned; my Hyundai was more reliable - 2012 Mercedes-Benz M-Class
  By fabllc - December 24 - 12:39 am

  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.

  Mercedes is not of the quality it used to be - 2012 Mercedes-Benz M-Class
  By scholla - March 17 - 9:32 am

  For the last 35 years I always had at least one Benz in the garage. Currently have a 2007 550s and a 2012 350ML. Bought both new/first owner. 550 s -19,000 miles - Air Condition not working. 350ML - 6,000 Miles - electronics defect: give wrong error messages and no error messages. Now, the ML is at the shop because the engine may have to be replaced. Local dealer in Palm Beach says MBUSA asked them to perform "more tests to identify the problem". (Car is in the shop already 3 days.) Two issues here: (1) MB now sells cars that do not work properly, even after short use. (2) How MBUSA deals with the problem: They make little/no effort to make things right. This is no longer a good make.

  Terrible Service from Mercedes - 2012 Mercedes-Benz M-Class
  By tracy97035 - May 24 - 8:36 am

  In 2012 I researched purchasing either a Mercedes or Acura. I had exceptionally great service with Acura in the past but chose Mercedes and assumed their service would meet the same expectation. I was wrong. I ordered running boards over a year ago and still have not received them. I now had to take my rubber drivers side mat into dealership due to a recall and am told not to hold my breath for the new one. Mercedes called me to say I would be put on their "preferred" list...but still have not received these items and they could not give me an eta on them. Waiting over a year for parts is insane. I wonder what the future will hold when I need service/parts ordered. I looked at Acura today..

  The worst vehicle I ever own. - 2012 Mercedes-Benz M-Class
  By neversummer78 - July 19 - 2:57 am

  I purchased my 2012 ML350 Bluetec back in November 2011. After 2 weeks, the first problem I had was car was pulling to the right at highway speed. After left it with the dealer for about a week, they finally realized that it was bad tire which took them a few more days to get replacement. Next, I was having problem with car loosing power when driving over a long distance or for a few hours. There is no error message on the dashboard nor that the dealer can replicate. Anyway, I start documenting them on video using my phone. They finally acknowledge but still no solution for it. Along with the car loosing power, I was getting error with PRE-SAFE Inoperative error and Ad-Blue low level
