What owners report

Owners of this model year most often describe two things: a no-start condition in which the electronic steering lock or ignition switch does not recognize the key, and tail light assemblies whose connectors overheat, melt or burn. A smaller group reports front-lamp and SRS warnings. Many of these reports arrive between roughly 30,000 and 90,000 miles, and both of the main patterns tend to appear without warning.

  1. Steering

    No-start with locked steering wheel (ESL/EIS)

    • 37 complaints (26%)
    • median 80,000 mi at 8.0 yrs old (33 state mileage)
    • owner-quoted repair $1,350 (median of 12 quotes)
    • filed 2013–2025

    Owners describe inserting the key, being told to remove it, and finding the car will not crank while the steering wheel stays locked and the shifter remains in park. Interior lights, radio and door locks still work, and battery checks come back normal. Complaints say the vehicle had to be towed and that dealers diagnosed the electronic steering lock, the electronic ignition switch, or both, with repairs commonly quoted around a thousand dollars or more. Reported from about 28,000 to 133,000 miles, most often in the 40,000 to 90,000 mile range, usually after a normal shutdown and with no warning beforehand.

    Recall 22V168000

    What to check: Ask whether the electronic steering lock or ignition switch has ever been replaced, and try several cold starts with both keys. Confirm the car starts reliably and the wheel unlocks before buying.

    2 excerpts from owner complaints in NHTSA records

    “I drove without problem to a local store, less than 4 miles away. I was in the store 5 minutes. When I came out and tried to start my car, the steering wheel was locked in place and the dash said take key from ignition . The lights and radio worked, however the windows would not work and the car would not turn on. Also, the shift was stuck in park and could not be placed into neutral without an override.”

    NHTSA complaint #10781361, filed 2015-10, 88,700 miles

    “On tuesday, june 9, 2015, I drove my car to work and parked at approximately 7:45 am. I did not get back into the car until 4:30 pm on the same day. When I attempted to start up my vehicle, it would not start. I called a mechanic friend, and he determined that it is a faulty eis which is the same problem that other people are describing here. As it stands right now, I will never buy another mercedes benz!!!!”

    NHTSA complaint #10724990, filed 2015-06, 107,000 miles
  2. Exterior lighting

    Tail light connectors overheating and melting

    • 27 complaints (19%)
    • median 61,108 mi at 5.9 yrs old (24 state mileage)
    • 2 mention a crash, fire or injury
    • filed 2013–2018

    Owners report a bulb-out or check-tail-lamp warning, a fast-blinking turn signal, or a tail light that is dim or dead. On inspection they find the bulb holder, connector or ground wire scorched, melted or burned, sometimes with a burnt-plastic smell inside the trunk. Some replaced bulbs and holders and had the problem return; complaints describe dealers declining warranty coverage and selling replacement assemblies. Mostly reported between about 40,000 and 110,000 miles, often after a warning message appears while driving.

    Recall 14V1770002 related service bulletins

    What to check: Pull both trunk-side lamp covers and look at the bulb holders and ground wire for browning, melting or a burnt smell; check that all tail, brake and turn lamps work. Ask whether the tail light ground recall was performed.

    2 excerpts from owner complaints in NHTSA records

    “Started off as a rt. Tail light message, a strange flashing rt. Turn signal ( rapid flashing). As I went to inspect the tail light bulbs, I found the light assembly plate melted at the connector to the light plate. The brown wire was so hot from the evidence that it melted the plastic all around. The brown wire is fried black. Could had started a fire.”

    NHTSA complaint #10532317, filed 2013-07, 45,000 miles

    “Passenger side tail light is considerably dimmer than the driver side. After examining the passenger tail light, I noticed that the connector of the wire harness connected to the housing that is housing all the bulbs is partially melted and it is extremely hot when the lights are on. I also checked the driver's side and it looks like the exact same thing is happening on there, too, but so far to a little lesser extent. Looks a lot like a fire hazard!”

    NHTSA complaint #10525105, filed 2013-07, 65,000 miles
  3. Air bags

    Air bag and SRS warning lights

    • 46 complaints (32%)
    • median 75,500 mi at 9.1 yrs old (14 state mileage)
    • filed 2013–2021

    Complaints describe the air bag or SRS warning staying lit, sometimes appearing each time a passenger sits in the car. Owners also report being told recall parts were unavailable, in some cases for many months, and one owner says a dealer would not accept the car on trade-in while the air bags were non-functional. Some note the SRS warning appeared alongside a no-start condition. Reported across a wide mileage spread, from about 34,000 to 150,000 miles, often at the time recall notices were being received.

    Recall 15V711000Recall 16V363000Recall 17V017000Recall 16V0810002 related service bulletins

    What to check: Have the VIN run against open air bag recalls and confirm the work was actually completed, not just scheduled; check that the SRS light goes out after the bulb self-test at startup.

    2 excerpts from owner complaints in NHTSA records

    “Takata recall I have received several notifications regarding recall for my mb 2008 C350 re faulty airbags. I have called the dealership several times where I purchased the with no help to repair. They offer no help at all. I am concerned about driving given what may happen and thus drive very little and only short distances. What can be done to get this resolved and feel safe driving my car? Thank you. …”

    NHTSA complaint #11045102, filed 2017-11, 58,000 miles

    “The dealer is telling us they will not take our car for a trade in as the air bags do not work and no replacement parts are available. They told us on one will buy the car as the air bags do not work. We are now out thousands of dollars!”

    NHTSA complaint #11045142, filed 2017-11, 49,000 miles
  4. Electrical system

    Intermittent electrical failures and stalls

    • 20 complaints (14%)
    • median 88,700 mi at 7.1 yrs old (19 state mileage)
    • 1 mention a crash, fire or injury
    • owner-quoted repair $932 (median of 6 quotes)
    • filed 2013–2022

    Owners describe the car failing to start intermittently, stalling while driving, warning lights coming on, and in one case a speedometer malfunction. Others report ABS, stability control or cruise control becoming inoperative, and one owner traced a no-start to a blown fuse after replacing a fuel pump. A further report describes smoke and fire damage at the instrument panel area traced to radio wiring. Scattered from about 49,000 up past 130,000 miles, often described as intermittent before becoming permanent.

    Recall 22V1680001 related service bulletin

    What to check: Check that all warning lights extinguish after startup and that ABS, stability control and cruise control function; ask for any history of fuse, wiring or control-module repairs.

    2 excerpts from owner complaints in NHTSA records

    “I was driving down the road and turning into king soopers shopping mart when my car just died. I thought it was the battery and coasted into a parking spot. I then checked my stereo and interior and exterior lights to see if it was the battery. It wasn't, they all worked fine. But turning the ignition to start the car did nothing. It seemed the steering wheel was locked. After playing with the steering wheel for a few minutes it unlocked itself and I was able to drive again. …”

    NHTSA complaint #10627843, filed 2014-08, 49,000 miles

    “After a few years of driving the vehicle the following stopped working causing difficulty driving the vehicle ABS/eps inoperative cruise control inoperative”

    NHTSA complaint #11399778, filed 2021-03, 133,000 miles

Buying note. A pre-purchase inspection focused on cold starting with both keys and on the condition of the tail light connectors covers most of what owners report here. Ask for documentation of completed air bag and tail light recalls, and budget for the possibility of a steering lock or ignition switch repair.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records.

Example complaints

Electrical system: “On sunday, june 27, upon returning to my car I discovered that the key would not disengage the steering column lock to allow me to turn the ignition switch to the on position or steer the vehicle. In addition, the gearshift could not be dislodged from the park position. I contacted aaa. A test of battery revealed that it was fully charged. …”

NHTSA complaint #11104682, filed 2018-06, 71,906 miles

Air bags: “Passenger seatbelt is clicked on, but it kept on beeping showing that its not click on while driving. It does that very often since I got the car back in 2011. The same as the passenger airbag, the light sensor keeps on popping on and off while driving too. I dont know if this a problem I should take care of myself because of my daily driving.”

NHTSA complaint #10717574, filed 2015-05, 67,000 miles

Steering: “I was driving and all of a sudden I heard a snap , as soon I try to pull over my steering wheel becomes very stiff, very hard to turn. Had to turn the car off and call for a tow truck. When I open the hood it smell like something burnt and I saw the belt in pieces. I spoke to my mechanic and he confirmed it was the belt and the idle pulley. Very dangerous situation and alot of c class cars are having this same issue. Hopefully mercedes benz can fix this before a tragedy happens.”

NHTSA complaint #10676868, filed 2015-01, 62,000 miles

Exterior lighting: “After I took my 2008 mercedes C350 to the dealership to have them do the repairs for the recall on the tail lights/bulbs. I keep getting the check right rear turn signal . The blinker will work fine, then after 10 minutes of driving it blinks very fast and the warning light comes on. This issue is getting worse. This is an extreme safety hazard and must be fixed immediately. Please advice! Everything appeared to be working fine until I got my vehicle back from the service dept. They changed the bulbs.”
