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.

The C-class has a surmountable amount of complaints pertaining to the ignition switch and steering lock. Both of which can go out at anytime, including while driving and being stranded in desolate locations without warning. I've had to replace both parts and the cost is unfair to the consumer because there is obviously a defect that is not being acknowledged. Both instances, I parked my vehicle, went into a business establishment, returned to my vehicle to leave and found myself stranded. Thank god, I was in safe locations but what if I wasn't. these cars are not reliable and these problems need to be fixed immediately. Also, Mercedes is not sure if this can go out while the vehicle is in motion which is even mor scarier.

My 2008 C300 with only 68,000 decided to die with no warning. I drove the car to the dealership had a taillight fixed then parked the car. The next day the car wouldn't turn on. All the lighting in the dash turns on but I'm getting a notification saying remove key from ignition. This shouldn't be happening! I have done some research online and am getting an idea that is is the eis. This system is designed to be operated multiple times a day, it shouldn't be failing.

Waking up to go to work, I attempted to start my car. I have have no problems with the vehicle since I purchased it a year ago, and with only 65K miles I didnt expect any problems. Since im not a car guy I got it towed since it wouldnt start. No ticking no nothing, and no warning at all. The mechanic said the battery was in good order but it was the eis that was the problem. Looks to be a major concern and a common problem for other owners. What a way to start the week of christmas in Texas with 70 degree weather

Woke up to go to my car and it would not start. I was headed into work and was late because of it. I tried relaxing everything thing from fuses to new key to new battery. Nothing worked. It kept making a ticking noise when I would turn the car on. The lights would light up but car would not turn over. I own a 2008 C300 and noticed it's a known issue with this part but Mercedes will it fix the issue.

Steering lock failed. 10 cent motor will not lock steering wheel. Causes car to think it is stolen, disables the entire car. Left me stranded in freezing temperature with no warning. I got gas, got in the car to leave to work, and nothing worked. This is very dangerous. Luckily I was able to get someone to pick me up, as my cell phone was about to die.

I parked the car in the garage early after noon in November 2014, and some time later that day the car would not start. I turn the steering wheel right then left thinking it might be a steering lock problem and kept messing with steering column trying to find problem being possibly a pinched wire and the the instrument cluster lights came on do a self check then car started. Used scan tool to retrieve codes and none were found. Second incident occurred when I parked at a gas station and paid for gas and the car did not start, nor did the usual instrument cluster lights come on when the key is inserted and turned as in the first time it happened. I started to adjust the steering column such as to raise the wheel and the lights came on, and I turned the key and the car started. Ran a diagnostic check for codes and still no codes stored. Third incident, parked the car after leaving church service and then was asked to move it from the lawn so the yard could be worked on. I started the car and turned the wheel as to back it up into a different location. I shut the car off with the wheel turned all the way to the right and then went to start it 2 to 3 hours later and it would not start and steering wheel is all the way to the right and locked in that position. Things I checked. Charged battery, both key fabs lock and unlock vehicle, the key is recognized by the security system but will not start the car. The key is also recognized when in the ignition. Audio warning comes on when key is left in ignition with door open. I believe the problem is in the steering column, only because every incident that has involved the adjustment of the steering column caused it to start and now with the steering wheel turned all the way to the right gave it the final failure status.

A few months back, my wife was stranded in her office parking lot as the car won't start. When she put the key in the ignition it would simply make clicking sounds but will not start. She was able to lock and unlock the car. We called aaa who checked the battery and said it was working fine. The aaa rep said that he had seen this problem quite a few times before in the mb cars and we would have to call mb or they can tow it to the dealership. We then called Mercedes Benz (mb) road side assistance who came and checked the car. The mb rep said that there is an issue with the electronic steering lock and it will need to be replaced. They gave me a quote of around $1500 over phone. Finally I had aaa tow my car to my mechanic and got it repaired for around $800. While researching this problem, I was shocked to see that there were 1000S of threads online where the owners of 2008 and 2009 C class were complaining about the same issue and how each one had to shell out anywhere from $1200 to $1600 at the dealership to get it repaired. I called mb and they admitted that this is a common issue but cannot do anything about it. I was quite appalled at this situation where this being a known issue faced by 1000S of mb customers but mb would not fix it. Here is a sample of google search where you will find multiple people reporting this problem - https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=utf-8#Q=2008%20mercedes%20C300%20electronic%20steering%20lock even youtube has multiple videos where customers have recorded this issue. Electronic steering lock, electronic ignition lock and electronic stability control are known and very prevalent issues related to C class of year 2008 and 2009. As I customer, I would appreciate if the nha can look into this and help customers recover the money they have spent towards the repair of these issues.

I replaced the battery and key due to car not starting ($600 and 1 week in the shop). 2 days later, the new key failed to start the car due to the same issue. Eis failure will cost another $1200. This should be part of a recall, I was stranded twice and it is a common problem with this model.

We parked the vehicle in a store parking lot after driving for 40 minutes, went into the store for 30 minutes came out and car would not start, steering would not unlock and shifter would not come out of park. Towed to Mercedes Benz of san jose and was told electronic steering lock had failed. Contacted Mercedes Benz as vehicle only had 52,000 miles and Mercedes customer relations stated this was not the first time they had heard of this. They gave $200 toward the $1100 repair. I asked if this could of happened while I was driving and he stated he never heard of that but did not guarentee it was not possible. If this had happened while driving the wheel would have locked and I would not have been able to steer.

Hello, I inserted my key into my 2008 C300, but the car won't start. It turns as it should, but the car isn't starting. The battery for the car is new and reads 12.6 V when tested. The radio and lights work, but the windows won't roll up or the sunroof, and the glove compartment doesn't light up. With the key inside the ignition and the door opened, the car notifies me to remove the key from the ignition. I am not sure what's going on, any ideas?

Update: Oct 19, 2015 my car wouldn't turn over. The lights, radio and battery were fine. I tried to jump the car just in case (it wasn't the battery) had the car towed to the dealership the next day. The following day the dealership informed me it was the eis switch (electronic steering lock). Price tag $1212 and some change.

2nd time with same eis issue in one year. Ignition would not turn over but all lights, radio, etc were working just fine. It cost me $1300 to get it fixed the first time after having it towed to a dealership. Was not covered by warranty. A year later I have to do it all over again"!"! it is ridiculous that Mercedes does not recall this issue as it is so common after reading so many posts about it.

Drove my car home and it ran fine. The next morning the car would not start. Dash lights and radio came on but engine would not turn over. Took my vehicle to dealer and found out it was the eis switch that is bad which seems to fail in the model. It cost me $1500 to replace switch. Mercedes needs to do a recall or reimburse for repairs because there are over 2,000 complaints on this part and year vehicle.
