STEERING,ELECTRICAL SYSTEM07/22/2026
My kids and I went into a football game and when we came out I used the key fob to unlock the doors but the vehicle didn’t recognize my key fob when I tried to start it. There were no lights or warnings leading up to this incident. The dash didn’t say anything besides “remove key from ignition”. We were stranded for 5 hours before I had to have it towed. It cost roughly $2000 to have it repaired with no clear reason for why it happened. It was a censor on the steering column that was somehow deprogrammed while we were in the stadium and suddenly failed to recognize its own key fob once it was inserted into the ignition. The anti-theft security feature kicked in and I could not get the vehicle to respond or bypass the system and it left me and 4 children stranded in a very dangerous area for several hours with no information as to why this happened or how to avoid it in the future. The steering column locked up when the tow truck driver tried to load it and caused a significant amount of added expenses on to the repair costs and towing costs.
FUEL/PROPULSION SYSTEM02/28/2026
I noticed fuel / gas smell from my vehicle. I looked up cause for this type of occurrence. I was referred to a recall bulletin for this particular cause - Recall Campaign #2013020002. My vehicle (VIN #) is not on the recall list. Both MB dealerships in my area state I would have to cover the cost to replace the Fuel Filter Flange. I am certain the Fuel Filter Flange is defective and should be listed in the recall. I pulled up the rear seat and removed the cover to expose the Fuel Filter Flange. There was gasoline on top of the Fuel Filter Flange. (I have documented with pictures).

After a fuel fill-up, I smell fuel inside the cabin and outside by the gas tank opening. This causes a constant stress..., what if there is a fire? I heard and read so many similar complains and concerns. This should constitute for a RECALL. What is the responsibility of NHTSA to the consumer's safety.
FUEL/PROPULSION SYSTEM08/08/2024
When we fill up the SUV with gas, there is a very strong odor of gas outside of the passenger door & some odor "inside the SUV. We looked online Motortrend.com said Certain 2011-2012 MB CLK 350 4matic are being recalled for a potential fuel leak caused by a crack in the fuel filter flange, Dec 15, 2012.' We stopped by MBenz of Lynnwood, Wa and spoke Garrett, a service rep. Garrett said that this was not a safety issue and we can continue to safely drive the SUV. We disagreed! We are very concerned because we believe there is a safety issue, our SUV has a crack fuel line could catch on fire while we are driving and potentially anyone around us could be affected. We did not get a malfunction or error message.

VISIBILITY/WIPER12/12/2023
Headlight bulbs failed. Owners manual states that the low beam bulb on the driver's side can be replaced by simply removing back cover, inserting hand and removing and replacing bulb. However, this is fraudulent. Every mechanic and the Mercedes dealers state that the bumper and possibly fender must be removed to replace this SAFETY item. The bulb went out on a trip and could not be replaced even though the bulb was readily available and I purchased it at a Walmart but could not replace it. Even though the Walmart replaced bulbs, after I waited 2 hours they told me they could not do it. I took it to two mechanics and they said they "did not have time" since it required disassembly of the vehicle. The Mercedes dealership said they could not provide an estimate because it required substantial time and disassembly. Now I have a car that has a bulb out, it cannot be driven at night, and to replace the bulb it requires an appointment at Mercedes and apparently hundreds of dollars of expense for labor. Like windshield wipers, tires, etc, etc, this is obviously a CRITICAL SAFETY ITEM and Mercedes has committed fraud in its representation that the bulb can be owner replaced. MY CAR NOW IS A DANGER driving at night. The NHTSA has statutory responsibility for the safety of vehicles and the internet has endless entries about the difficulty of replacing the headlight bulbs on this vehicle. I pay taxes. Do something.

After inserting key - there is no response. Tried several times. FOB locks and unlocks the doors. After a couple of days - it started with no problem. A week later, we are having the same problem with no response after inserting the key in ignition switch. This troublesome to know that I cannot rely on the ignition switch working all the time.

FUEL/PROPULSION SYSTEM06/29/2023
I noticed the smell of fuel coming from my vehicle, specifically when I top off at the gas station. This is dangerous as fuel can combust if ignited. I took the vehicle to be service, to find out about the fuel odor and was advised of the NHTSA recall. Upon researching I see that although the NHTSA recall #12V557000 specifically covers this issue, when entering my VIN, the recall does not appear for MY specific vehicle, which is a 2011 GLK-350. It appears there are several affected vehicles not included in the recall. This is a failure on behalf of Mercedes Benz as it is simple to conclude that the issue includes more vehicles than initially recalled. These vehicles need to be included as well.
