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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2012 Mercedes Benz GLK350 Warwick, RI Crash

AIR BAGS

On August 17, 2025 I rearended a vehicle in front of me who jammed on their brakes for no apparent reason. We were the only two vehicles in the area. Upon impact, the following airbags deployed....steering wheel, driver knee airbag. I sustained injuries to my lower extremities from the exploded knee airbag which contained metal components that impaled my skin. I continue to receive treatment for multiple injuries and the wounds that have not healed. My safety was at risk due to the metal components (shrapnel) deployed via the exploded knee airbag. I also sustained injuries my left wrist from the steering wheel airbag, and my left chest from the tightening of the seatbelt. The local Mercedes Benz dealer recently towed the vehicle from my home address to their facility for inspection of said airbags. As of today, I have not received any report from MBUSA.

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.
