Exactly what failed

NHTSA files every complaint against a named sub-assembly, not just a system. This is the difference between knowing it was "the engine" and knowing which part of it — the list to hand a mechanic.

When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

SEATS

This sprinter van is a 2500 4x4 to exit or enter the vehicle you must use the step, this requires, you to twist sideways and reach down with your foot to the step. On the seat which is attached to the metal frame there is a plastic piece which holds the seat switch, which is held on by a plastic plug and a reusable plastic rivet. As you enter or exit the van and use the step your weight pushes the leather seat against the plastic which holds the seat switch and causes the attachments to fail causing you to fall. I Have fallen twice once into traffic.

I had the same issues as identified in a current recall entitled: Model 907 Sprinter. Model Year 2019-2022 Update Instrument Cluster Software. In my case the instrument cluster remained non-functional upon vehicle start-up exactly like the recall with an added problem of the ignition push button would not shut off the vehicle. I was left with a vehicle I could not shut off without an operational instrument cluster. While my model year and model number match this recall, for some reason my VIN number was not included in the recall so the dealer will not upgrade the software and fix this problem. The scope of this recall must be corrected to include my VIN number.

POWER TRAIN

CRITICAL SAFETY CONCERN: Vehicle shifts into NEUTRAL during normal start sequence, could roll over passengers. Component of concern: Electronic "Wiper" stalk shifter is easily shifted into NEUTRAL during normal start sequence. Problem encountered several times in our 2021 Mercedes Sprinter- the stalk shifter is located directly in front of the "START/STOP" ignition button. To start the vehicle, you must: 1) Press and hold the brake 2) Reach under the shifter and press the "START/STOP" button The problem is pressing the brake is also the "safety interlock" for shifting out of PARK. The breakout force on the shifter stalk is VERY LOW, causing it to be inadvertently shifted into NEUTRAL during a normal start sequence. This is a safety concern, because often we will start the vehicle, and then exit the drivers seat to load passengers (small children and/or wheelchair users). The vehicle does not give any indication (no physical movement of the shifter) of shifting out of park- other than white letter on mid-dash indicator going from "P" to "N". The vehicle could easily be shifted into NEUTRAL and run over passengers during the loading operations.
