What 2 owners told NHTSA about the 2025 Mercedes-benz Sprinter 2500 Passenger Van

Subject: Transmission Failure Safety Complaint I am submitting a complaint regarding a serious transmission problem with my vehicle. While driving, the transmission suddenly failed, and the vehicle lost the ability to move properly. The car would not accelerate as expected and had difficulty. In some instances, the vehicle would not move forward or reverse. Warning indicators appeared, and the transmission Fault Stop began showing abnormal behavior such as delayed shifting, jerking, slipping, or sudden loss of power. This created a dangerous safety risk, especially while driving in traffic and at intersections. The vehicle has been maintained regularly, and this issue occurred unexpectedly. I believe this transmission defect may affect other vehicles of the same make and model and should be investigated for consumer safety. The dealership attributed the issue to wrong fuel, but I am concerned the actual issue involves transmission failure. I have a fuel purchase receipt showing the correct fuel was purchased before the incident. Despite this, the dealership suggested wrong fuel as the cause. I respectfully request that this matter be reviewed and appropriate action be taken. Vehicle Information: Make: Mercedes-Benz Model: Mercedes-Benz Sprinter Cargo Van 2500 Year: 2025 Mileage: 71599 VIN [XXX] Date of Incident:03/24/2026 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Refer to Safety Recall 25V747 and see the attachment which outlines our complaint. RV does not comply with requirements of FMVSS 110 and 49 CFR Part 567. We were the reporting party to the manufacturer and according to NHTSA database, our VIN is not present for the required recall service/extended fuel tank replacement. The RV manufacturer and dealer are not presently responding to requests from us to have the recall service completed. We believe they have not correctly reported additional safety concerns as are described in the attachment. The manufacturer has communicated that since producing RV's in 2021, they have improperly weighed RVs which has resulted in inaccurate OCCC labeling and we believe owners unknowingly operated RV's over GVWR. Our RV's OCCC is 333 lbs. A 174 lb weight savings per Safety Recall 25V747 will not bring our RV into compliance as we have a certified curb weight of 8700 lbs. and believe other same year/models have the same curb weight. Additionally, we are inquiring if Remote Vans is required to provide a cargo carrying allowance in addition to the occupant weight i.e. 600 lbs. for four seat belted passengers per FMVSS 110. We have also filed a complaint/attachment with Oregon Department of Justice Consumer Protection on 11/28/25.
