NHTSA Complaint #11625256 — 2021 MERCEDES-BENZ SPRINTER 3500

My van has periodic lack of acceleration or dead pedal. There are no warnings that this will occur. This shows itself when trying to advance from a stopped position. When I push the accelerator the van either does not move at all or barely crawls forward. This can last 15-45 seconds. There are no RPMs from the engine. Once the pedal starts to respond, the issue will resolve. The problem is you need to get to that point where the engine can make rated power. Once you put in in drive, and if you're able to idle away from the parking spot, you may find that when you need power to move up a hill or through an intersection, it just isn't there. You can't wait a minute with your foot to the floor when you're in the middle of an intersection. sometimes it will slowly accelerate. This has caused multiple situations where I thought I was going to die due to being out in cross traffic and failing to be able to move. It happens both in reverse and forward. It happens even though I have warmed up the engine for 5 minutes or more. It seems to happen more at altitude but has also happened at sea level. It doesn't seem to matter if the outdoor temperature is warm or cold. The dealer can not detect a problem. I have read many accounts of this happening on MBZ forums. This must be a known issue with MBZ yet they have failed to solve it. Some think it is a sensor initiation issue after a cold soak. Someone is going to die because of this problem if MBZ is not forced to fix it.
