RECALL NO: 19V-868 | VIN: [XXX] | CASE #: [XXX] VEHICLE: 2013 Mercedes-Benz GLK350 (X204) DESCRIPTION OF SAFETY PROBLEM: This complaint concerns a failure to adequately remedy NHTSA Recall 19V-868. Since [XXX], my vehicle has been grounded at Mercedes-Benz of Westmont. The dealer performed the recall out of sequence, ignored documented circuit faults, and refused mandatory Xentry commissioning and SCN Normalization, leaving the SRS system inoperative and uncertified. NHTSA records (Ex B-27) confirm the recall remains "Incomplete." MANUFACTURER ABANDONMENT OF SAFETY OVERSIGHT: On Feb 26, 2026, an MBUSA Executive Referral Manager (Case #[XXX]) stated by phone he would not read my 61-page safety complaint and classified the failure to verify the recall as a "dealer issue" due to franchise laws. Only 28 minutes after admitting he would not read the file, he sent an email falsely claiming he had "reviewed the documentation" and closed the case. By refusing to audit a documented failure to certify a safety repair, MBUSA is in active violation of its duty to ensure recall completion under 49 U.S.C. § 30120. COERCIVE SAFETY THREAT (49 U.S.C. § 30122): Service Manager Blake Farmer and Advisor Harry Arroyo explicitly threatened to remove the new airbag and reinstall the original defective recalled inflator (Ex B-6) during a billing dispute. This is a direct violation of 49 U.S.C. § 30122, which prohibits a dealer from knowingly making a safety system inoperative. DEALER NEGLIGENCE & ADDITIONAL RISKS: Dealer negligence regarding Part #204-440-68-41 (Ex B-17, B-26) caused a 5-day delay, resulting in a nationwide backorder. Furthermore, technician video (Ex B-10) shows an active oil leak (Code P2610-29), a fire/stalling hazard per MBUSA TSB LI05.20-P-067123 that the dealer refused to diagnose. ATTACHED: 61-page filing with 28 exhibits and 3 notarized affidavits. The 60-day federal deadline is April 4, 2026.

I am writing to express a serious safety concern regarding the Mercedes-Benz GLK 350, particularly related to the fuel pump system under the rear passenger area. It has come to my attention that the fuel pumps in these vehicles emit a strong, unpleasant odor every time the car is refueled. This poses a significant risk to both the driver and passengers. I have personally experienced a similar issue with a 2013 Mercedes-Benz GLK350, where the pumps were constructed with a substandard plastic material that, over time, will melt and start dripping from the top of the pump. This degradation of materials significantly compromises the integrity of the system, creating a serious hazard that could, in the worst case, lead to catastrophic outcomes, including fire or explosion. I strongly urge Mercedes-Benz to investigate and address this issue as a matter of priority. The potential consequences of ignoring this matter are severe, and a permanent solution must be found before any further risk is posed to the safety of vehicle occupants. Thank you for your immediate attention to this critical safety concern. I look forward to your prompt response and the implementation of necessary corrective actions. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting a safety issue involving my Mercedes-Benz GLK 350 following repairs performed by an authorized dealership, Critz Mercedes-Benz in Savannah, Georgia. I brought the vehicle in due to persistent noise when shifting gears and steering-related symptoms. I asked the dealership to fully investigate the cause of the issue and not limit the diagnosis or repair to any single system, as I am not a mechanic and relied on their expertise. I paid $5,674.90 for the repair. During the process, a service advisor contacted me regarding an additional charge of approximately $800, which I approved to ensure the vehicle was repaired correctly and to avoid any claim that I declined recommended work. After the first repair, the noise was still present. I contacted the service advisor and returned the vehicle. After the vehicle had already been released to me, the dealership’s own technician recorded a diagnostic video stating that a suspension arm was “about to break.” I have the video and the email containing the link. This confirms the vehicle was returned to me with a serious unresolved safety defect, and I returned it after learning of this issue. The dealership performed additional work and released the vehicle again, but the noise remained. I asked the service advisor to hear the noise in person, after which he verbally stated that “all GLK 350s do that.” I later sent a text expressing my concern, and he replied in writing stating the same. I also have a saved and transcribed voicemail repeating this statement. Since the repair, the condition has worsened. Steering noise continues and braking effectiveness has degraded, requiring longer stopping distance. Because steering and suspension directly affect braking and vehicle control, this presents a safety risk. Due to the expense of the failed repair, I have no immediate alternative transportation and have been forced to continue driving the vehicle. The vehicle is available for inspection.

Out of no where when I cranked my car the airbag light came on in my car. I took it to have a diagnostic test done and the report shows short circuit at steering gear and driver air bag squib. When I look up my make and model a previous recall for driver airbag comes up, but it's not assigned to my specific vin. Also, there was a previous recall for the steering gear bolts on my make and model but it also was not assigned to my vin. NO ONE AT MERCEDES WILL HELP ME! THEY STATE NO ONE HAS THE ABILITY TO ASSIGN RECALLS TO A SPECIFIC VIN IF IT WAS MISSED IN ERROR. My vehicle currently has no airbags cause the system has disabled itself to prevent possible deploy malfunction. Can you please help me. Thank you.

MY 2013 GLK350 WAS STATIONARY AND I WAS PARKED IN MY PARENTS DRIVEWAY IN ILLINOIS. IT WAS NIGHTTIME AND I WENT TO GO CLOSE THE PANORAMIC ROOF SINCE I WAS GOING INSIDE AND IT WAS LIGHTLY RAINING. TEMPS OUTSIDE WERE MILD SINCE IT WAS MAY 27, 2016. WHEN I WENT TO CLOSE THE ROOF I HEARD A CRUNCH SOUND BUT DID NOT NOTICE IT WAS SHATTERED. I CLOSED THE SUN BLIND AND IT WASN'T UNTIL I OPENED THE BLIND THE NEXT TIME MAY 28, 2016. MY SISTER AND I BOTH LOOKED UP AND NOTICED THE GLASS WAS SHATTERED. THE REST OF MY FAMILY ALSO NOTED THE DAMAGE ALSO AND WE TOOK INCLUDED PICTURES. I CALLED MB USA AT 800 367.6372. ADAM THE REP I SPOKE TO SAID I NEEDED TO TAKE IT TO THE DEALERSHIP TO SEE IF IT'S PART OF A RECALL BUT WHEN THEY LOOKED IT UP THERE WAS NO RECALL FOR MY VIN?? I FOLLOWED UP WITH VANESSA AT THE 800 AND SHE SAID THE SAME THAT SVC GUY DID AT DEALERSHIP. I ESCALATED MY COMPLAINT FOR RESOLUTION, NO OBJECTS OR ROCKS, ETC CAME IN CONTACT WITH THE GLASS AND THE TRACK WAS CLEAR OF DEBRIS. I LOOKED ON INTERNET AND NOTED SEVERAL SIMILAR INCIDENTS OF THE GLASS SHATTERING AND SOME WITH GLASS EXPLODING OUT OR IMPLODING??! MB IS NOT CLAIMING RESPONSIBILITY WHICH I DO NOT UNDERSTAND! I HAVE ESCALATED AGAIN AND I AM STILL WAITING TO CONNECT WITH MB USA TO DISCUSS SINCE THIS IS CLEARLY A DEFECT. IT DOESN'T MATTER WHETHER YOU'RE STATIONARY OR MOVING THIS IS A SERIOUS HAZARD. I HAD TO GET THIS REPAIRED AND COST ME UPWARDS OF $1600 OUT OF POCKET.. BUT HAS COST UP TO $2K PER INCIDENT. COME TO FIND OUT THIS IS NOT ONLY HAPPENING TO OTHER CAR MODELS AND SO FAR THERE ARE COMPLAINS FILED AGAINST KIA AND NISSAN.

My car started making a funny sound above the right tire on the way to my hair apt on March 13, 2023. On the drive home from the appointment, my front axle came off in the middle of the expressway at 9:30 PM on 1-10 in Houston, Texas. I was so scared that I was going to die. Cars were coming so fast and swerving all around me. I turned on my emergency flashers and called 911 immediately. I don't think that I have ever felt so helpless and panicked in my entire life. By the grace of god, I was not hit and tow trucks came within 10-15 minutes. They told me that most people get hit and that I was lucky to not be hit at 80 miles per hour at a dead standstill. We towed my car to the nearest repair shop where they confirmed that the plastic u-clamps had deteriorated which caused the front axle to become detached. Insurance would not cover it. Imagine my surprise when I discovered that Mercedes had recalled over 38,000 small SUVS for the exact same issue, but that my Mercedes was not a part of the recall. When I filed the complaint with Mercedes, they said that they would not cover the cost to repair it because my vehicle was not a part of the recall. I don't want what happened to me to happen to anyone else ever. I believe that Mercedes is aware of this issue and does not want to take responsibility.

TWICE I'VE HAD THE ISSUE WHERE NONE OF MY LIGHTS WORK WHILE I'VE BEEN DRIVING. NOT SURE ABOUT THE HEADLIGHTS, HOWEVER BOTH TIMES I HIT MY TURN SIGNAL TO TURN (DOESN'T MATTER RIGHT OR LEFT) AND THERE IS NO INDICATOR VISIBLE ON MY DASHBOARD. ALSO THERE IS NO TICKING/SIGNALING NOISE. WHEN I'VE PULLED OVER AND HAD MY PASSENGER GET OUT AND LOOK AT MY REAR OR FRONT TURN SIGNALS NOTHING WORKS, PERIOD. I DID MENTION THIS TO THE DEALERSHIP THE FIRST TIME AND THEY COULDN'T FIND ANYTHING. I'VE NOT BOTHERED A 2ND TIME SINCE THEY COULDN'T FIND ANYTHING THE FIRST TIME. TO SOLVE THIS ISSUE; I HAVE TO POWER MY CAR OFF FOR A FEW SECONDS, THEN START MY ENGINE BACK UP. BOTH TIMES THIS HAS SOLVED MY TURN SIGNAL ISSUE. NOT SURE IF MY FLASHERS HAVE THE ISSUE OR NOT WHEN THIS HAPPENS. KNOWING ME I WOULD THINK I WOULD HAVE CHECKED IT, HOWEVER I CAN'T RECALL. *JS

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
