Takata recall, eis, esl seized up and car won't start anymore, common problem with this car and repair is costly should be recalled since it's a manufactured defect and not caused by the user, this problem can leave anyone stranded in the worst of situations and it can seize up while vehicle is in motion causing accidents and danger to the driver and passenger

My car would not start... nothing when the I turn the key into the on position. The battery was checked and was good. This happed several times over months but twice the car started after sitting maybe 8 hours. This happened a third time a few months later. I was stranded and ended up having the car towed home. I tried starting it the next day..nothing. My authorized Mercedes repair shop informed me that it was the electronic ignition module. I waited 2 weeks for the part. Cost was $1600. Just a note... I occasionally heard a faint noise like a motor running inside of my car whenever I turned the ignition off for a couple years but did not think it was any thing to be concerned but apparently this may have been a sign of a failing part.

Approximately two years ago the electronic steering lock module (esl module) failed and the vehicle would not start while the steering wheel and transmission shifter were locked. Had to take to the dealer to replace the module at a cost of $840. Right now the electronic ignition switch module (eis module) failed and again the steering wheel and transmission shifter were locked and the car will not start. Dealer is asking for $1150 to repair. These are known defects in Mercedes vehicles. I asked Mercedes Benz usa to cover the cost of the repairs of the vehicle in both cases and they have refused to admit that these are known defects and to repair the vehicle free of charge.

Esp control module as I was driving on the highway, specifically getting off the interstate on a curved road, all of a sudden the following message/code illuminated across my dashboard, "brake" ebr ABS esp inoperative. I wasn't sure what this meant and I was extremely alarmed and nervous. As soon as I could I brought it into the shop and the technician told me it wasn't a brake issue, it was a faulty electronic stability control panel that needed to be replaced. The technician told me that he had just replaced these in about 4 other vehicles. Same exact problem. After doing research, it is a major safety concern because it reads the wheel data from the sensors as well as the ABS module which prevents traction and slippage when driving on the road, when making sharp turns, or even turning left or right. The car seems to fishtail. It also prevents stability on the road in the event of a crash. I've also noticed it has affected other areas of the car such as the turn signal, cruise control mechanism, steering column and starting up the car has also been an issue. I've had to turn the ignition switch a couple of times to get the car started. The car is also driving rougher than usual. This is a major concern for us because I am a single mother and I have a nine year old son who drives with me frequently. I'm worried about our safety. Not to mention our front driver and passenger takata airbags still have a recall that have yet to be dealt with. It has been well over a year and the problem still hasn't been resolved. This esp control module costs $1,500 to replace and I cannot afford this. I'm driving around in a ticking time bomb just waiting for something to happen. It is a major concern and needs to be addressed immediately. Thank you for your time and I certainly hope you take this seriously and place this on the recall list to avoid a bad situation.

Last week I drove my daughter to school. Then I went to the gas station and turned the car off. When I tried to start the car to leave, it would not start. It did not do anything. I could not even roll the windows up. The car did nothing other than say "remove ignition key." The battery was tested and fine. It had just been replaced 1 month ago. The tow truck driver brought it to my mechanic who then said it had to be brought to the dealer. The Mercedes dealer said it was the eis/steering switch. The cost will be $1900. I've called other mechanics. No-one can fix it because Mercedes has the parts and coding exclusively. This is a lot of money and with the amount of complaints it should be a recall. Last year my car also experienced the SRS light malfunction. I brought it to the dealer and this was also another huge expense. The dealer did not take the responsibility of a recall. They acted like it was a big surprise.
