2010 ML350 starts right up when cold in the morning. If I go to a store and return to the car when I insert and turn the key nothing happens no lights on dash. After struggling for 5 minutes trying everything from locking/unlocking opening doors turning key slowly it finally starts. This problem started a month ago and is becoming more frequent now. After reading numerous complains on forums I assume it is the esi (electronic system ignition) and it is an expensive fix so I called merc Benz and complained and asked if there is a recall. There is no recall and customer service told me she is not a mechanic and wants me to take it to the dealer. As I am aware this repair cost customers from 1200-1800 dollars.

Two issues with my ML350 2010 car - 1) electrical - gas gauge went to zero while driving even when car was three quarters full of gas. After I stopped car and restarted engine, gas gauge went immediately back up to three quarters full. 2) failed brakes - I was driving into a parking spot slowly using brakes and when I was about to come to a full stop, the brakes failed and wouldn't stop the car completely resulting in me driving over a parking meter. It felt like the car accelerated as well after hitting parking meter but I was able to stop car after pressing on the brakes again. Thankfully no one was hurt given slow speed and no one being on sidewalk at the time.

On August 1st 2017 bought brand new battery from Mercedes-Benz of easton. Installed in next couple of weeks without any issue. On Sept 12th 2017 around 2.45pm started the car(in the driveway) and went inside to get my mobile. When I came out to te car, saw big smoke inside and immediately switched off the engine. Saw flames coming underneath of passenger seat and immediately poured water. Later observed battery ignited the flames and even top of the battery started melting. Called mbusa and reported the incident, and was promised that a supervisor will call back. Waiting to hear back from mbusa. It was so scary, and I can't even imagine what if this happened on freeway.

Vehicle won't go into park, drive, neutral, or reverse when I push the button to tell it to. Vehicle's turn signals don't turn on when I move the handle up or down to try and turn them. It handle clicks as if it is turned on but blinkers do not turn on. Almost got hit by another car when this accrued because the blinkers didn't come on and the car didn't see that I was stopping. Very scary and dangerous since I have two small children.

2010 Mercedes ML350 led style brake lights fail gradually, one led or one row at a time, gradually diminishing the brake light intensity. Both the right and left brake lights are failing in the same manner. The hazard of losing vehicle brake lights is obvious.

The ignition switch needed to be replaced because the car was not able to identify the electronic key anymore to the tune of $1,300+ on a four year old car, at this price point is ridiculous! additionally, a new key was needed.

As described above. Instead of blowing a fuse, fuse housing melted from fire and heat requiring replacement of the entire housing with all fuses and relays. I brought it up to Mercedes Benz attention and their response was as the part got replaced at this point it is only an "alleged" problem. They do not want to accept their own service mechanic 's description of what happened. I am afraid this car has all the potential of bigger fire hazard and potential for accidents and deaths. I am bringing this to your attention only because you may have prior reports on this make and model and I am doing my civic responsibility it was unfortunate 14 people have to die with GM ignition switch problem.
