Vehicle stalled without warning, and I was advised by a mechanic that the fuel pump control unit was reporting a fault through the onboard diagnostics port and the check engine light on the dashboard. It was necessary to replace the fuel pump control unit as the defect was intermittent and subject to occur at any time the vehicle was being driven. There is no available solution save the replacement. I had the fuel pump control unit replaced at my cost and after replacing it found information concerning the NHTSA recall campaign online. The defective fuel pump control unit was discarded upon replacement and is not available for inspection. I believe the failure of this fuel pump control unit is a direct result of the recall not being complied with. I believe the manufacturer; Mercedes Benz USA is responsible for my costs expended in repairing this defect under the recall campaign because they did not notify me of the recall. I purchased this vehicle from an authorized Mercedes Benz USA dealer, my personal contact information is a matter of record of the sale, and I believe Mercedes Benz USA had a duty to contact me concerning the NHTSA recall campaign #2023010002 concerning this vehicle.

Mechanic found water in spare wheel well. Had to replace fuel pump. In February,2023, Mercedes Benz notified me of a recall, NHTSA Recall I D: 22V955 ; water intrusion in the spare wheel well. And, stated their local dealer would repair vehicle or reimburse me for the cost of repair, if I had the repair done already. I submitted receipts and documents pertaining to the repair.

Due to water in the spare wheel well, (Recall ID:22V955) our fuel module and fuel pump went out. While driving in traffic on I-5 our car stalled then stopped which put us at risk of a crash.The first time (July 2022) It was repaired by Cooper's Auto Repair), After the 2nd time it failed again in Aug 2022, once again as we were driving, our mechanic at (Boyle's Foreign Car Repair) Aug 2022 & Dec 2022 (replace) decided to do an inspection of the whole car to see why this was happening, upon inspection he found water in the spare wheel well, He pulled out the plug to stop accumulation. 2 months later (Feb 2023 )we received the recall letter. In the letter it states that MBUSA would reimburse repairs performed prior to the recall. MBUSA is now refusing to reimburse for replacement but also refusing to find and fix where the water in entering. We reside in a very wet part of the country and see this as a continuing issue. There also is condensation in the back tail lights, which was not there until this issue started occurring. The car was previously in S Cal so there was no issue with water accumulation until it was moved to the rainy Pacific NW. We are fearful of using this car during very wet times as we do not know if this (failure of pump/module) will occur as well as condensation and water being in the back tail lights possibly resulting in the car stopping during it being driven. Therefore putting our lives in potential danger of an accident.

TOOK OUR 2012 MERCEDES-BENZ ML350 BLUETEC TO THE DEALERSHIP NUMEROUS TIMES DUE TO AN OVERPOWERING FUEL SMELL AND BURNED PLASTIC IN THE CABIN OF THE VEHICLE. WE HAD TO STOP SEVERAL TIMES BECAUSE WE FELT SICK AS IF WE WERE GOING TO PASS OUT AND/OR THROW UP. BUT, THEN IT STARTED TO AFFECT OUR CHILDREN AND WE DEMANDED THAT THE DEALERSHIP FIND THE ROOT CAUSE. THEY FINALLY DETERMINED THAT IT WAS A FUEL LEAK AROUND THE FUEL INJECTORS THAT COMPLETELY CHARRED COMPONENTS IN THE FUEL INJECTION CAVITY. IT COULD HAVE CREATED A FIRE OR LOSS OF CONTROL OF THE VEHICLE. I NOTICED THAT THIS HAS BEEN REPORTED TO THE NHTSA WHICH IS WHY I AM ALSO REPORTING THIS NOW ALSO. MY VEHICLE IS ONLY SERVICED BY THE MERCEDES-BENZ DEALERSHIP. THE DEALERSHIP IS CHARGING ME $1900 FOR THE REPAIR OF THE CHARRED COMPONENTS. NHTSA ID NUMBER: 11090864 REPORTED EXACTLY THE SAME ISSUE. I THOUGHT I WAS GOING CRAZY UNTIL THEY FOUND THE ROOT CAUSE OF THE SMELL. NOW THAT THERE ARE AT TWO REPORTED CASES OF THIS BOTH IN 2012 MERCEDES-BENZ ML350 VEHICLES IT SHOULD BE INVESTIGATED.
