2 Engine And Engine Cooling problem

Failure Date: 11/07/2023

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.

8 Engine And Engine Cooling problem

Failure Date: 07/22/2016

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.

9 Engine And Engine Cooling problem

Failure Date: 11/11/2015

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.

10 Engine And Engine Cooling problem

Failure Date: 11/09/2015

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.

11 Engine And Engine Cooling problem

Failure Date: 08/19/2015

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.

12 Engine And Engine Cooling problem

Failure Date: 08/15/2015

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.

13 Engine And Engine Cooling problem

Failure Date: 05/01/2015

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.

14 Engine And Engine Cooling problem

15 Engine And Engine Cooling problem

Failure Date: 03/03/2015

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.

16 Engine And Engine Cooling problem

Failure Date: 01/29/2015

I drove to work on the 29th, and to and back an appointment, I went to leave work that evening and my car would not start. The was no indication that there was a problem. And we were in the middle of an ice storm, I called mercedes road side assistance and I guess my assistance expired so they told me it would be $175 to tow my car, so I used my verizon roadside assistance to pick up and take to a friends shop to fix but because of the storm I was not able to get my car picked up for 25 hours and since it was Friday night by that time my car didn't get looked at by my friends repair shop until Monday 4 days later I find out that the vehicle cant be fixed by anyone else but mercedes, because everything in the car is seized up and no one knew how to get it unseized. So Monday at noon I called mercedes roadsideagain to get the car towed again. Because of the wonderful customer service from the roadside assistance team at mercedes they ended up sending 3 tow trucks over to pick my car up, the first one showed up after my first shop closed, the second tow truck was unable to pick up the car because they didn't know it wouldn't go into gear so finally another 24 hours had past before they got my car which is 1/4 of a mile away from the repair shop where it was. My car has been broke for almost a whole week know and still know one knows what is wrong with the car in the mean time the dealership has no loaner car for me to use and I spent 3 hours sitiing in a disabled car in an ice storm waiting for someone to come and get me. It really sounds like the same problem everyone else on this site has experienced who knows how long it will take them to kfigure it out at this pace, I will update this if I ever find out.

19 Engine And Engine Cooling problem

Failure Date: 07/13/2014

It appears that the eis module has failed, I have done some research and have found several other consumers having the same issues with this particular year and model vehecle. This concerns me. Why hasn't any recalls been done to fix this issue. It seem like this is a safety issue. What if I were driving my car and the eis had malfuntioned. I would have lost power to my vehicle as well as all stearing abilities. Could you please investigate this issue?.

20 Engine And Engine Cooling problem

Failure Date: 06/11/2014

The engine dies. This is known by Mercedes Benz and is being reported all over. The ignition system needs to be recalled and replaced. Why is NHTSA dragging its feet on this issue. Someone will be injured or killed by this, if it has not already happened.

21 Engine And Engine Cooling problem

Failure Date: 06/09/2014

Shame on you Mercedes Benz! it appears to be a known issue that the steeling lock goes out leaving your loyal customers stranded with no ability to start the car. Ok! now, I am told the cost to repair is $1450 for the part and the labor. Looks like my next car will be a BMW! (steering lock went out at 80k- leaving the car unable to start).

22 Engine And Engine Cooling problem

Failure Date: 06/04/2014

Car completely stuts down. Nothing worked and would not restart. This has occurred to many other cars and the manufacturer is well aware of this condition. Does someone have to be injured or killed (if this has not already happened) before this defect is addressed ?.

23 Engine And Engine Cooling problem

Failure Date: 06/05/2013

Many people have complained about the same issue in many forums. I wonder if someone has to be injured or killed (if not already) before something is done. The car arbitrarily and without notice dies and will not restart. It leaves the driver completely vulnerable, wherever it occurs. This is what happened in my situation. Nothing worked, I had to call, to be told that this is a battery issue. It was not, as determined by the tow truck company and the dealership, after the car was towed to them. Is this ever going to be investigated and recalled before further damage and/or injury occurs ?.

24 Engine And Engine Cooling problem

Failure Date: 02/12/2013

Am concern with this 2008 mercedes I own with similar issues as GMC cars with the ignition/key/engine just stopping. . . Car lost all power and wheels locked. The car was driving well one moment then stopped. Was not injured but was left stranded at night getting off work with no car. . . . Had to have it towed out of parking lot which was quite difficulty with wheels locked. . . . And taken to mercedes dealership. It was repaired for 800. 00$. . . And I asked if this would happen again and was told "probably". . . . Have noticed online this has been a know issue in the 2008 model. . . . . My question is why is mercedes not held accountable for faulty part like GMC is. . . . . And I have hear this has happen while the vehicle has been moving too. . . . That scares my greatly. . . . . The dealership of nashville would not even address any concern with me about this. . . .

25 Engine And Engine Cooling problem

Failure Date: 09/01/2011

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.

26 Engine And Engine Cooling problem

Failure Date: 05/21/2010

Two separate instances of commanded acceleration with my 2008 mercedes C300. I purchased the car from a private used car dealer in September 2009 with 10,500 miles. On November 1, 2010 I experienced my first instance of uncommanded acceleration while slowing to a stop in a driveway. The engine suddenly accelerated to a high rate and struck a parked truck immediately in front of my car. I shifted into reverse and the car sped at maximum rpm across lawns and the street until finally returning to normal. At no time were the brakes able to have any effect on slowing my speed. This incident was not reported to the police since no property serious damage occurred however I immediately contacted the dealer from whom we purchased the car. They claimed we needed to contact mercedes since the car was still under warranty. When I visited the local mercedes dealer the following day they initially expressed interest in inspecting the car right away however nearly 2 weeks passed before they told us to bring the car in for inspection. They kept the car for 3 days and told us they found no mechanical or electrical faults. We were greatly disappointed with their findings and sent a certified letter to mercedes USA with full details of the incident. Their reaction was that the vehicle was operating as designed. We continued to operate the vehicle and on may 21, 2010 a second instance of sudden uncommanded rapid acceleration occurred. I was pulling out of my driveway at a slow rate while slowing to a stop as another vehicle passed by. Suddenly the mercedes accelerated uncontrollable and struck the passing vehicle causing it to overturn. The circumstances were nearly identical and I am positive the gas pedal was not being depressed. My car has bluetooth capability and I have a bluetooth compatible cell phone. Perhaps this caused interference with something in the engine computer system. My car is presently in an undriveable condition and mercedes has not yet come to inspect it.
