Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Car was operating fine when I got home around noon parked on the street outside my house, at 2pm I was trying to leave. While starting the car the warning showed up on my dash stating "remove key from the ignition". called aaa to ensure that the battery was ok. Aaa showed up and inspected the car. Battery was up to standards. Mechanic said to use a spare key to test out the issue. Grabbed a spare key and the same warning showed up on the dash. Mechanic said that I need to take the car to the dealer and get my eis system replaced and a steering column. Took it to the dealer, and they told me the same thing. Here you go, final bill $1,600 out the door. Make this a recall item if everyone is having this issue.

Took car for routine service at local mb dealership on 9/3/16 and was told both front parking lamps/lights are not working, further informed that it is not simple light bulb blow out but something has caused the whole molding/casing holding the light has melted and the entire assembly will have to be replaced. The service adviser stated that he has seen this type of problem before with this type of vehicle. I am not a technical person and can forward email and the details of issue as provided by dealership. I consider this serious safety and fire hazard and wanted to know if this problem has been reported to you before by consumers or by the manufacturer Mercedes Benz. Mileage on form is approximate

Vehicle was stationary on the side of a highway due to a low tire pressure warning. Vehicle was turned off. Minutes later, attempt was made to turn vehicle back on. Vehicle did not turn on (engine did not turn). Vehicle was towed to home where same phenomenon occurred, vehicle did not turn on although key was inserted and ignition switch rotated, engine would not start. 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.

After I turn the car off, the front left light on the top continues to stay on. If I move the knob back and forth slightly, then shuts off, at least for a while. I just had to deal with a dead battery yesterday when I was getting ready to leave work. From what I have recently researched, this is a common issue among this model. Has a recall been made for this" will this cause any other issues with the vehicle? if it is a shortage in the electrical, am I in danger of the vehicle not reacting appropriately while driving at night or at a higher speed on the highway? is there any risk of it catching fire? there is also a sensor that needs to be replaced. I am not that car savvy, but I believe it may have something to do with fuel injection or something filtering properly. Is that another common issue"

I drove my 2010 C300 to an appointment 2 miles away and went to start the car after an appointment and it would not start...tried having it jumped but it didn't work...had it towed to the dealership who told me it was an electrinic steering malfunction and needed to be replaced for $1460...there was no indication that there was an issue until it jist stopped working...unacceptable and from what I habe learned this is a rampant problem with Mercedes and should be considered a recall.

The auto lock would randomly unlock and lock at the wrong time causing the door handle to not be responsive anymore.. Mercedes charged 1000 dollars to fix his when it is a common problem and a very big safety issue. Unfortunately I can't afford to fix my door which makes me think if I get into a car accident what would I do?

The contact owns a 2010 Mercedes Benz C300. While the vehicle was parked, the passenger side low beam head lamp continued to illuminate even though the vehicle was turned off. As a result, the battery drained. The vehicle was taken to a dealer who repaired the vehicle under NHTSA campaign number: 14V177000 (exterior lighting); however, the failure recurred on numerous occasions. The manufacturer was not notified of the failure. The failure mileage was unknown.

I drove 500 miles from Chicago to mississauga, ont. Canada. Trip was uneventful. The day after I drove the car to a Honda car dealership, ironically, to look for a car for a relative and parked. Returning one hour later I was able to open the doors with the remote but when I tried to start the car everything except for the radio went dead. The car was towed to the Mercedes dealership 7 kilometers away. The programmed part had to be ordered so it took two business days to get my car back at a cost of $1071us. It was troubling to reflect on the possibility that this could have happened on one of the rest areas I stopped at in the middle of nowhere along the route. I can't decide whether I would rather not have this system and have my car stolen or left stranded with the nearest town miles away. The dealership said the system just malfunctioned just like a light would blow out. Not good enough system for an expensive car. Thanks for your involvement.

I recently had an issue with my eis on my 2010 C300, the car had roughly 60000 miles when the issue occurred. I parked my car in a parking garage, and when I went to leave work, the car wouldn't start. The steering column was locked, and I was unable to put the car in neutral. The issue seems to be one that occurs in a large number of Mercedes cars with similar make/model/mileage, which is generally right outside of the mileage for the standard warranty. Mercedes doesn't allow the issue to be fixed by licensed dealers, and can only be fixed by a dealership. I believe this to be a conflict of interest and somewhat of an ethical dilemma. I am not sure if the eis would ever go out while driving, but if so, that could result in safety issues for the driver.

Went into work and came back out to my car not starting. Battery just recently replaced within the past 6 months. Had the battery charged and tried to do a jump and still nothing. Had to get my car towed to the auto shop only to find out I have a failed eis, meaning my electronically ignition system has failed and its going to cost me 1000 to fix. My car is out of warranty but I find this a major inconvenience. This is supposed to be a reliable car the reason I chose to get this car and something like the ignition has failed. I wish there was something that mbusa could do to pay for a majority of the issue or even do a reimbursement. This can be a safety issue as well, I always think what if I was out of town or what if I had a emergency and because of this glitch I simply have no car and now I'm dependent on a ride until I can get this fixed!

I received notice of a safety recall involving the rear tail lights for my 2010 Mercedes C300. This car had previously been in an accident and declared a total loss. However, it was rebuilt, inspected, and certified as road worthy. The Mercedes dealership refuses to perform the recall work on my car, stating that the fact that the car was a total loss invalidates any warranty and a safety recall is considered warranty work. I feel that a safety recall is not optional, and that Mercedes needs to perform this work, regardless of warranty eligibility.

  • 35,000 miles
Went to start car and nothing. Steering locked and difficult, due to all wheel drive to tow. There are many cases documented about eis/esl failures on Mercedes enthusiast forums. The problem is prevalent on the internet. This could be very dangerous on a crowded highway, in a crime ridden area or just in an emergency. The car will start one minute and won't on the next start. Mercedes claimed no financial responsibility for the failure in my case. The car was 2 months out of warranty.
