Car worked fine, all the sudden it wouldn't turn over, I would put the key in and turn it and nothing would happen, I was stuck and had to catch a ride, lucky that I was able, a car company that is supposedly reliable shouldn't allow there cars to completely give out on people during the middle of winter storms and not take ownership, when the customer has taken good care of the car. Talked to several mechanics and turned out it was the Electronic Steering Lock (ESL) module that had malfunctioned probably due to the software and electrical. Due to this only the Benz dealerships can repair, I had to tow it to a dealership and was charged around $2000 after haggling over the price. Terrible experience and should be recalled by MB, I have seen many complaints about this online and was very disappointed there wasn't a cheaper solution. Was both a safety issue, inconvenient and very costly.

Error codes 1200 and 1208 regarding the lack of tension on the timing belt due to a worn sprocket. It was certified by two different Mercedes Benz mechanics with ample experience with these cars. Vehicle still runs but I was warned to stop it and fix it before it is a major problem.

This is the 2nd time this has happened. I turned the car off and came back out and it would not start. The front wheels were locked. The key went in and turned. The lights and power was there but, the car would not start. The front wheels were locked and so was the drive shifter. The first time the car was in a parking lot and my wife was left stranded. The second time was in out driveway. We came home to get something and when we went out it wouldn't start.

Issue with cam gears. Mercedes has know about this issue for many many years. There should be a recall on this issue. Car is unsafe with this problem and costs about $8000 to fix. From the online class action lawsuit from 2013 "the engines are equipped with defective gears in their balance shafts or with defective idle gears. These defective gears wear out prematurely, excessively, and without warning, causing the vehicle to malfunction, the 'check engine light' to remain illuminated, and the vehicle to misfire and/or stop driving."

On July 21,2016 at 9am and I parked my car and went to work, 2 hours later came back and try to start the car, did not start. Car door locks and trunk locks open and close but when I turn the ignition on, no response, no display on instrument panel around speedometer gauges. No hissing or cranking or beeping noise also. Steering column was also locked up and inoperable.about 2 years ago command screen with lcd display that controls all functions smoked a little and was shut down display. Going to the last weeks problem steering column has locked me out and also eis that is the communicator from ignition switch and alternator or started do not function also. I happened to see more than hundreds of car with the same year group and model has smiliar problems.my car mileage was 93121. I would like make this as a manufacturing problem of unreliability of the parts and the manufacturer let it roll off assembly line with out doing diligent testing of the parts involved from the suppliers for reliablity and durability and in turn cost the consumers $2000-3000 of unnecessary expense/troubleshoot and fix/ than you very much for your help.

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.

Last week 8/11/2015 I drove to the lumbar store, parked the car and upon returning to the car, the key turned completely to the right, the dash lights came on, the ringing noise sounded, but the car did not turn over, nothing happened. The dash read remove the key from ignition. I called my mechanic with the issue and he said use your key fob to lock and unlock the car; that did not work, still nothing. I called the tow company the battery was fully charged ( I purchased it last year 2014). The tow company disabled the cable to the battery waited 30 seconds and reconnected the battery, still the key would not turn the engine over. Because the lumber yard locked their gate at 5 pm the car was scheduled to be towed the next morning. The car started the next morning, I allowed the tow company to tow it anyway and have their mechanic assess the problem. Thorough-out the day the tow mechanic attempted to turn the car on and determined the car would intermittently start. The next day I drove the car to a foreign car service shop, they stated the eis system is not always recognizing the key and only a mb dealership can fix ignition related problems. I called and got a quote, the eis part and labor will cost me $872.31 includes taxes (assuming this is the problem). As a note, I used my other key and still had the same problem. This morning I used the key I always use and it started. Off to the mb dealership.

Car has faulty steering lock and has to be replaced at a high expense. This seems to be a very common problem as I learned visiting various websites and forums.

The key locks and unlocks the doors the lights come on and the dash lights up. You can insert and turn the key but the car will not start. The stering wheel is locked and it is stuck in park. I tried power jumping and it did nothing, I didn't think the battery was the problem but had it checked anyways. The battery checked out fine. I check the fuses that are associated with the starter and all was fine also. Only thing left was get it towed to the Mercedes dealership, found out that the steering wheel lock issue is a common thing with my car model, eis failure seems increasingly common on 2008 models for some reason.

Myself, as well as passengers have been cut by the sharp edge of the peeling chrome along the top rim of front cup holder. I told my dealership and they wanted charge me over $500 to replace it. When grabbing change, drinks, or anything from cup holder the front of ones hand is constantly exposed to this sharp edge. Not a safety issue but similar to the peeling chrome, the painted text on several control buttons on dash have been peeling off for several years. A clear sign of poor quality/craftsmanship. This is my first Mercedes and I am not impressed with the interior craftsmanship of what is supposedly a top luxury brand. Also have had to replace battery 2 times in 2 years and have had problems with battery dying within first year of 2nd battery. Dealership wants to charge fee to inspect last battery.

Got in my car last night to go home and attempted to crank it. It would not start. The key turned in the ignition and lights worked but the engine would not turn over. Last year in February I had to have the car towed to the dealership by roadside assistance and have ignition switch replaced for a similar situation at my cost. I am awaiting news from the dealership as to the problem this time but this is ridiculous for this vehicle to have this type of complaints from so many consumers and Mercedes not stand behind this product by recalling it. I am a woman and had no one to assist me or provide transportation home. You buy a product thinking that it is dependable but this car isn't it.
