Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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.

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.

NHTSA ID 11538396 · filed Aug 14, 2023

I'm having the same issues as described in Recall no. 12V557000. However when I called Mercedes they mentioned that my Vin wasn't part of that recall. I don't understand how can that be when my car is 2011-2012 glk350 model as described in recall and I smell gas, can see gas leaking and the flange where my fuel filter is cracked as well as the flange to the fuel pump side. This car as well as many other Mercedes have two separate flanges that are prone to crack and not just the fuel filter side but the fuel pump side as well. there's many forums where they all have complained about this issue. If you can smell gas, there's obviously fuel vapors leaking and not to the mentioned the physical leak that is landing everywhere you drive. This is a serious fire hazard and is extremely harmful to my kids and passengers.

The dealer informed the contact that the dealer and the manufacturer would cover 50% each for the cost of the subframe replacement; however, the contact needed to pay as well for the replacement. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.

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.

I WAS DRIVING ON THE INTERSTATE, AND I HEARD A VERY LOUD BOOM FROM MY VEHICLE, FOLLOWED BY CRACKLING SOUND. MY SUNROOF SHATTERED AS WELL AS THE FIXED PIECE BETWEEN MY WINDSHIELD AND MOVING PANE OF SUNROOF. THE FOLLOWING DAY, I DROVE THE VEHICLE TO A LOCAL DEALERSHIP AND WAS TOLD AN OBJECT STRUCK THE VEHICLE AND CAUSED THE DAMAGE TO THE VEHICLE. THE FIRST PANE OF GLASS HAD A 1 IN DIAMETER HOLE WITH A STARBURST PATTERN AND THE SECOND PANE HAD VERY LITTLE VISIBLE DAMAGE TO IT OTHER THAN THE HUNDREDS OF CRACKS IN IT. I AM CONCERNED ABOUT WHY THE FIRST PANE OF GLASS THAT IS ANGLED OUTWARD TO THE ROAD IS NOT MADE OF SAFETY GLASS OR METAL AND WAS CONSTRUCTED OF TEMPERED GLASS. I WAS LUCKY THAT I HAD MY BLIND CLOSED AND THAT THE GLASS DID NOT SEPARATE FROM THE VEHICLE AND STRIKE ANY OF THE VEHICLES BEHIND ME. AS I TOLD THE GENTLEMEN AT THE DEALERSHIP, IF ROAD DEBRIS HITS MY VEHICLE I SHOULD NOT HAVE TO REPLACE A THIRD OF MY ROOF. ROCKS HAVE HIT MY WINDSHIELD AND CHIPPED IT, BUT FOR A ROCK TO HIT MY VEHICLE AND CAUSE SUCH EXTENSIVE DAMAGE IS POOR DESIGN OR QUALITY OF MANUFACTURING. *TR
