The High-Pressure Fuel Pump (HPFP) and corresponding fuel delivery pressure regulator/sensors have suffered an internal mechanical failure. The system intermittently fails to maintain commanded rail pressure, leading to critical engine cylinder misfires (P0302, P0304) and severe long-term fuel adaptation breaches (P00C600, P008992, P017184, P218862). This defect is physically causing raw gasoline to leak into the combustion chambers, oil crankcase, and exhaust tract. The vehicle and all compromised components are fully intact and available for immediate inspection upon request. My life and the safety of surrounding motorists were put at risk during a severe incident on the highway. While…

The ECM harness was wired too close to a sharp metal piece within the engine bay, the clip MBZ uses to secure it was insufficient to hold it back, the thick wiring harness got caught on the metal piece and overtime got cut deeply causing a short with thermal issues spreading to other components, the wiring harness melted together and caused so much heat in the engine bay that other components touching the thick wiring also have visible melt spots, if it wasn't caught because we got a shock from a metall component of the car and therefore realized there must be a short it could've potentially posed a fire risk.

On January 19, 2026, my neighbors / daughter noticed smoke was coming from under the van that had been parked for over 3 hours. Shortly after, he confirmed the van had caught fire. I asked him to call the fire department.

In August 2025, I had taken the van for a drive to charge things up, got home, put it in park and parked it in my driveway, which has a mild slope. ~ 30 seconds - 1 minute after me leaving the vehicle, it rolled backward out of the driveway, across a busy street and 1/4 into my neighbors yard. I was mortified, there is usually a lot of people walking their dogs, kids etc...and cars going by. The vehicle was stopped by the curb vs the 2nd back tire (Thie first one cleared the curb and was in my neighbors lawn. It ALMOST hit a BIG tree. I pulled it back into the driveway & checked it again, worried I may have somehow not put it in park, but it did it over and over again. Shortly after I put…

2023 Sprinter van jack was pulled out for the first time to be used last week and found to be unsafe. The jack base is crowned in center, the edges flare upwards and large gouge/groove in metal base, causing the jack to noticeably wobble and rock in manner that it is unsafe to use, fear of jack tilting and dropping van onto user of jack. Jack base has obvious defects and unsafe to use. Have contacted dealer and referred to MBUSA who provided a case # and no resolution to provide a safe jack to replace the defective jack.

I had tuned up my sprinter van around 64000 miles. I put new ngk spark plugs and ignition coils on it. Ran for a day then. The codes said the number one ignition coil was bad. Change that out and it ran for about 8000 miles. Then stated to go in lymph mode again. I decided to replace them with original Mercedes spark plugs and Ignition coils. But when I put them in the van had no power and was jerking. It was doing this before I changed them out. It had no power and would barely go up a hill. I researched and seen certain Merecedes Sprinter vans from 2021 to 2023. Had a recall on the fuel pump. But I don't understand why my van wasn't included. It's showing all the systems them the fuel…

Occasionally, the idle speed of the engine will drop to 400 rpm. When this happens, the vehicle does not respond to throttle input. If it happens in a parking lot, you can shift into park and coax the rpm higher, then shift to drive and move on. When it happens in the middle of an intersection while waiting to make a left turn, the story is very different. You can end up in a very dangerous situation. This has happened to me multiple times. I have not had an accident, but I have upset other drivers when I failed to clear an intersection in a timely manner. Knowing that the car will move when you press on the accelerator is critical for safely operating a vehicle. I purchased the vehicle new…
