2021 MERCEDES-BENZ SPRINTER 2500 Power Train Problems

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...

Engine throttle does not respond to input from accelerator pedal.

The contact stated their company owns a 2021 Mercedes-Benz Sprinter 2500. The contact stated that the gear shifter was shifted into park(P) and the parking brake erroneously activated; however, the vehicle rolled forward as if the gear shifter was in drive(D). The contact depressed the brake pedal and made several attempts to put the vehicle in park(P). There were no warning lights illuminated. The contact was not sure if the vehicle had been taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

I have had several occurrences of a stuttering and/or lagging acceleration when stepping on the accelerator.

At altitudes of over 5,000’ MSL the vehicle will not move when shifted into Drive or Reverse. No response from gas pedal. Vehicle will randomly hesitate with zero or poor throttle response when driving creating an extreme safety hazard.
