There is a problem with the engine control parameters which occurs at higher altitudes. The vehicle will not produce adequate power. This is not simply normal power loss related to density altitude. This is a malfuntion where the vehicle does not respond to the throttle, and produces only about 2psi of turbo boost even upon extended application of full throttle. This problem occurs only on sprinter 4x4 models with the OM642 diesel motor. I experienced this problem for the first time yesterday when pulling onto a 2 lane highway at 7,000 feet in the sierra nevada. The vehicle began to move but as I turned uphill to cross the highway it produced no power and I was stuck straddling the center line on a blind curve. Extremely dangerous. Had to turn the vehicle off and restart it and it behaved normally until later in the day, on a steep remote 4x4 road. Unable to climb a small hill due to lack of power. Could not be resolved through any combination of turning off, waiting, warm-up periods, activating/de-activating traction control etc. Had to use winch to climb mild grade. This issue is well known to the Sprinter community and has been repeatedly reported to Mercedes Benz USA with no response or resolution. There are no warnings, messages, store error codes etc associated with this issue. Many descriptions of this behaviour can be found online: https://sprinter-source.com/forums/index.php?threads/106595/ https://windinmyface.com/Sprinter-Issues_Breakdowns-WillNotMove_RPMsDropEngineLugs.html https://sprinter-source.com/forums/index.php?threads/103019/#post-1130969 https://sprinter-source.com/forums/index.php?threads/94746/ There are many more. This is a known issue, relating to engine control software, that is very dangerous and the manufacturer has taken no steps to remedy. It is beyond time for regulatory intervention. Thank you.

This van is under recall for roll away incidents. The van did roll away and now has $9K worth of damage from hitting a stop sign and a wall. The van has been at MB Stockton Ca for months and months with out a resolution. Mercedes Benz sent us a letter yesterday stating they deny all responsibility and advising us to pick up the van. The recall is not complete. This vehicle is 100% unsafe and now prone to more incidents, we have refused to pick up the vehicle. Mercedes has advised us to appeal the case with them which we have done. They continue to stall the situation.

My husband was stopped at a stop light on Sept. 9th when the van randomly (and without provocation) shifted itself from drive into park. We called the dealership to explain the problem and ask that they look into it. We made an appointment and dropped off the vehicle yesterday. Service Department called and verbally stated that they had taken a van on a test drive and that the van had acted "normally" and that they anticipated returning the van to us with the instruction that if we experienced the problem again to contact them. I was not happy with this response as I felt that the problem was a severe safety issue and not enough had been done to investigate it. I quickly googled "mercedes going into park on its own" and found an article detailing reports of 2010 mercedes sedans going into park on their own while the driver was slowing to stop (exactly as we experienced). An accompanying official mercedes benz service department memo in the article confirmed the problem, mentioned the "auto p" feature and blamed the problem on a faulty ignition switch. I called the service department back, referenced the memo and asked if a faulty ignition switch could be to blame. The service department stated that it would be impossible because the ignition switch has changed. They stated that my husband must have taken off his seat belt and engaged the auto p feature. My husband did not unbuckle his seat belt that day. The dealership returned the van noting that they were able to duplicate the issue and engage the auto p feature by unbuckling the driver's seat belt at low speed. My husband and I tried to duplicate and engage the auto p feature ourselves by unbuckling the driver's seat belt after it was returned but were unable to do so. Interestingly, mercedes benz has recently issued a recall for driver's manuals because they acknowledge that the directions for how to engage the feature as explained in the manual are incorrect. Unbuckling will not engage auto p.

Power steering hose is not long enough, is poorly connected/clamped, and has been disconnecting from multiple of these vehicles, causing an immediate emergency situation (loss of power steering), and an immediate vehicle breakdown. Mercedes is aware of this issue but has thus far failed to address it

I only have about 2200 miles on this vehicle but I have noticed 3 times that the electronic 4 wheel drive engaged by itself as I was moving down the road. Your are only supposed to be able to engage the 4 wheel drive while stopped. I never noticed anything until I saw the red light which comes on when the 4 wheel is engaged. I went on line to see if others had experienced this and I saw several reports of the system engaging and not being able to get it disengaged as well as having the vehicle not be drivable afterwards. I have not experience anything but it going into 4 wheel drive on its on without me engaging it. It occurred while in motion and twice on expressways and once onn a local low speed road

Vehicle accelerates uncharacteristically slowly upon cold start in cold temperatures / high elevation. Many documented cases in previous and current model sprinter which uses the same om642 diesel engine. Https://sprinter-source.com/forums/index.php?threads/71254/ there have been multiple times where I tried to cross an intersection or make a left across a highway upon recent cold start and the van accelerated very slowly, leaving me moving very slowly across the opposing traffic lane(s).

The 4wd in this vehicle does not disengage properly even when done per the owners manual instructions. Under 1,000 miles on the vehicle . For example, I stopped the vehicle, shifted to neutral, engaged 4wd and drove for 15-20 minutes on a dirt road. I pulled over to enjoy the view, put the vehicle in park but left the engine running. When I attempted to put the vehicle back into drive, the 4wd decided it was time to disengage (without me pushing the button to do so) and it made all sorts of loud grinding and clanging sounds as the mechanical parts bashed around. I went to neutral to disengage and that did not solve it. It refused to go back to 4wd either and the transmission was inoperable. I turned the vehicle off several times and finally got it to be drivable again in 4wd. All of this happened on a forest service dirt road, almost flat surface with just a slight angle backward if I took foot off brake.
