While driving on 95 highway taking an exit ( making a right turn roundabout) the steering wheel locked on me preventing me from continuing in the direction of the exit causing me to almost crash into the metal railings; because my wheels now where locked in a position that would force me to crash into the railings had I not stopped. I stopped and turn the car off and restart for the steering wheel and system to reset and unlock. This incident occurred around 2018 or 2019. I notified mercedes of what happened and I received notification of a recall on the steering. I had the recall checked on my vehicle and thought it was fixed. However, twice in November 2020 my car was stationary when trying to start the car, the steering was locked and the ignition would not start. Then after making several attempts car eventually started. I called mercedes and I was told over the phone by mercedes it could be my key faub. However, this happened a 4th time on Dec 24, 2020, numerous attempts to start car and car would not start, steering was locked. Car had to be towed to dealership. Was told by mercedes theres a fault in the steering lock modular. The electrical wiring is faulty and the entire steering modular has to be replaced. This is a major safety issue, and can cause accidents when it malfunctions while driving. I asked about the recall that was on the steering and was told the recall addressed a different issue with the steering.

10 Car Will Not Start problem of the 2009 Mercedes Benz C300

Failure Date: 05/11/2019

My C300 stranded me in deming, nm. We had left el paso heading home to phoenix. Quick bio break in dement, and that's where my C300 wouldn't start. The shop in deming said that the car would need to be towed back to the dealer in el paso. Turned out my steering column control lock module needed to be replaced. The dealership ordered the part and two day and $1,400 later I was able to drive back to phoenix. Between towing, lodging in deming and el paso, meals, etc I was out over 2k. This is so I can start my car. According to my local mb dealer my service advisor said he sees one or two a month with this problem. I picked up the car in 2012 with 50k miles. This issue came 70k trouble free miles later. Amazed that one little part could strand me with no warning.

11 Car Will Not Start problem of the 2011 Mercedes Benz C300

Failure Date: 03/28/2019

I am writing to file a complaint. The vehicle did not start after the key was put into the ignition. There were no warning lights. In addition, the vehicle did not start at all. The tow service was called. The tow repair representative indicated the problem may be the "ignition switch," as the battery was fine. The vehicle was towed to the dealership. The entire ignition switch had to be replaced. The cost was $1214. This is unacceptable. Fortunately, the vehicle was in a secure place -- the home garage. However, had it been in another location, a serious safety hazard could have occurred. The vehicle only has approximately 91,000 miles, so it is inconceivable as to why an ignition switch would need to be replaced. There was no warning. This is an item that is clearly a manufacturer's defect and should be under warranty.

Failure Date: 11/10/2017

We are a small family owned car lot that has been in business since 2005. We sold a 2011 mercedes C300 to a nice young couple last week. After only having it less than 24 hours, the customer called stating the vehicle will not start. Said went to start the vehicle in the morning and the steering wheel was locked and car would not start. The lights & radio turned on but it had a message on dash to remove key from ignition. We had to call a tow company to tow it to the mechanic and put them in a loaner car. Later that day I started doing some research and realized many many others are having this same exact issue and it is costing them $1600-$1800 to have the esl & eis replaced. It is insane how many of the same issue have been recognized and reported yet there is no active recall on this very dangerous, expensive issue with on a car that many people can only dream about having! I will attach the link also that I found the others having the same issue. . Read more...

I went to work and my vehicle was just fine. I left for lunch break stopped at the groccery store and went home which is just a few miles away. I parked my vehicle went inside to drop my groceries off and eat lunch and when it was time to return to work my car would not start! I was so pissed off! the steering wheel would not turn and the gears would not shift at all. I only have 30k miles on my car and one owner before me. I am the only driver and my car is in impeccable shape! I know it is not the battery because I just put a brandnew one in just 3 months ago. I do not understand why there has not been a recall for this issue because I see thousands of complaints about this repair so it is obviously a manufacturing issue. When I first bought my benz I fell in love with the brand. I have always been a Audi/BMW girl but vowed I would never go back until this issue. Mercedes does not treat it's customers right so this will be my last benz! recall this issue benz!.

Failure Date: 10/25/2016

The steering wheel is locked, and I cannot change the gear from "p". A message would appear "remove key from ignition" whenever the door is open. I have searched and it appears to be a very common problem in these models, where the eis or esl fails for no reason. The qoutes for this repair range from $1000 to $3000. I had to tow the car to my apartment, and now I have to tow the car to the dealership because they are the only ones who can solve this issue and reprogram it after installing the new parts.

32 Car Will Not Start problem of the 2009 Mercedes Benz C300

Failure Date: 10/21/2016

When I returned to my car in the parking lot after grocery shopping in the evening, the car would not start. The radio and lights on the dashboard worked and the seat moved, but the engine would not start. I had this car checked not too long ago and everything was fine, but the car just decided not to work suddenly. This is especially scary for a female stranded in a public parking lot at night. I did not get any warning messages before the incident. I had to call roadside assistance and try jump starting it first, which wasn't the problem as the battery was fully charged. I ended up having to tow the car early next morning because the dealer was closed and had to take a cab home. When I went to the dealer and stated all the "symptoms", mb knew right off the bat what the problem was, which to me is alarming. They told me they are 99% sure it is either electronic ignition switch or electronic steering lock problem and it would cost me $1200 to repair it. It obviously is a very common issue. They are very well aware of it, yet they are not doing nothing about it, as (they say) it is not a safety problem. How is this not a safety problem when the driver doesn't get a slightest warning or even a message that the car won't start and will leave you stranded wherever you are? as a young female living in a city without friends and family to help out, especially at night in a public space, this is quite frightening. I almost had a panic attack, because I didn't know what to do and never had to call roadside assistance. The only reason I had gotten a Mercedes Benz was for its safety. Mb site states: "true to their heritage, they're engineered to protect you in ways you might never have imagined. And with the hope that you'll never have to. " how did mb protect me? mb has only engineered the car to rip off customers and not live up to its brand. This is very disappointing.

33 Car Will Not Start problem of the 2008 Mercedes Benz C300

Failure Date: 10/14/2016

Car will not start while parked. Battery checked and tested good by aaa. Steering wheel locked. Car will not shift out of park. Towed to christian brothers automotive and problem was diagnosed as eis failure. Was told that this is a very common problem for this car. However, it is a 'dealer only' repair due to mercedes refusal to either sell parts or release codes to independent dealers. Was also told there is a lawsuit attempting to force mercedes to cease with the proprietary baloney. The repairs are very expensive and there is no alternative to the dealership. This needs to be a recall or, at the very least, all the necessary parts and codes need to be made available to independent repair facilities.

34 Car Will Not Start problem of the 2010 Mercedes Benz C300

Failure Date: 08/06/2016

Vehicle was towed to dealership, where it was repaired: faulty electronic steering lock (esl) and electronic ignition switch (eis), sum was about $1,600. All web information points to a common problem and may pose safety hazard, especially when trying to avoid unsafe situations, such as parked alongside a highway where cars speed by at approximately 65 mph. Issue is known and Mercedes Benz fails to acknowledge premature failure of ignition components.

35 Car Will Not Start problem of the 2009 Mercedes Benz C300

Failure Date: 07/21/2016

Stationary while at the rest area during a hot summer day on the side of the highway. The steering column or electronic steering lock (esl) failed and the car would not start. Car won't start and steering won't unlock. . . I stopped and cut the engine of and tried restarting the car it won't do anything. This particular part is faulty on most 2008-2009 mercedes C300. Several hundred thousands are having issues with this particular part and at moments they get it working and at other times not so much. This part needs to be recalled since it is a dealer only replacement part and no one can touch is besides the dealer due to theft and security measures. Mercedes has this particular issue cornered and is not doing anything to work with the customer.
