2020 Mercedes-Benz Sprinter 2500 Problems

What component or system failed or malfunctioned, and is it available for inspection upon request? The Adaptive Cruise Control turns off and then won't reset while driving. When the Adaptive Cruise Control turns off and then won't reset while driving. How was your safety or the safety of others put at risk? This causes the vehicle to immediately loose power. When traveling at highway speeds and vehicles are getting ready to pass us, then the cruise stops, we have been nearly rear ended multiple times on our last trip. Has the problem been reproduced or confirmed by a dealer or independent service center? This has been inspected but the service center couldn’t reproduce because it happens after several hours of driving. We had this problem several times while traveling from Denver Colorado to Pittsburg Kansas. If we stopped for fuel or food, and turned the vehicle off it would be fine on restart. If we were driving when it turned off we would have to follow another vehicle at a constant distance for more than 5 minutes to get the system to reset. Sometimes it worked sometimes it didn't. This is also a safety issue because we were having to follow fairly close to a vehicle in front of us to get the system to reset. We also tried turning the system off every hour or so, use the “cancel” button while driving, but it didn’t seem to make a difference. The system continued to randomly turn itself off. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? We took the Sprinter in to a Mercedes-Benz dealer service center and they checked everything and said it was fine. Then we took it back a second time and asked if there was some sort of calibration or computer software update needed. They inspected the vehicle again and informed us everything was up to date. I do not feel that this issue was being taken seriously as it is very nerve racking when it happens and then trying to not get in an accident when traveling

The contact owns a 2020 Mercedes-Benz Sprinter 2500. The contact stated that while in reverse, the rearview camera failed to display a rearview image. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to provide a cause for the failure. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V411000 (Electrical System, Back Over Prevention); but the VIN was not included in the recall. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was 51,000.

On November 28, 2025, I experienced a vehicle fire in my Mercedes 2020 Sprinter 2500 4WD van. The van engine was on and idling while heating up with the van heater blower on level 6 (out of 7). After about 45 minutes, I saw a haze first and then smelled smoke. Unsure of the source, I turned the vehicle off and exited with my dog. I opened the hood to look for smoke in the engine bay. No smoke under the hood. I contact Mercedes Roadside and open the driver side door where I see flames under the seat. I grabbed the fire extinguisher I installed and put the fire out within 20-25 seconds of seeing it. I believe the root cause of the fire was running the van blower at a high setting for a sustained 45 minutes. My dog and I were inside and definitely in danger. It scares me to think of a scenario where the van was idling with only my dog inside and something like this occurring. The incident is currently under investigation with MB USA and my insurance company, Progressive. No warning signs or dashboard messages. In general, the electrical wiring for my vehicle has been spotty and was completely rewired by the dealer service center in 2021. Currently, there is an issue blacking out the dashboard screen so there is no screen function including gps, entertainment, or vehicle info.

I’ve had two issues with my sprinter van that were transmission shift module that left me stranded with no way to shift the car into neutral. I was blocking a fuel pump and couldn’t get the car into gear. The first time I was stuck in a parking lot with the same issue. I can’t believe no one else had this issue. The screen message said “Service required do not shift gears” I purchased the van new in 2020. It only has 17000 miles on it. The dealerships Mercedes Benz in Sioux Falls and Mercedes Benz in Rochester Minnesota repaired the van.

repeated EGR clogging and malfunction: bucking or stumbling behavior, inability to accelerate properly, disabled shifting affecting ability to slow or stop without excessive use of brakes, Limp Home Mode suddenly without warning including inability to maintain a safe speed on highway and speed minimums that the vehicle cannot keep up (20 mph max while climbing moderately), unable to downshift when going downhill - relying solely on braking to keep speed below safe limit or speed limits. EGR failed again after cleaning, in as little as 3 months. No repair seems possible, only repeated cleanings. Since this happened so much, we have been in several unsafe situations due to the sudden and unheralded degradation of performance and safe use of the vehicle. Once repaired, the condition can come back immediately due to the computer still guessing that it is still in failure (limp home mode returned suddenly without warning as we merged onto an interstate with no exit for 7 miles uphill… and only made 20mph). Check Engine light could come on, and did, but never during the actual degradation of performance - and went often after a few run cycles. Mercedes dealers have confirmed and performed all services on the EGR and related issues (malfunction once caused the aircleaner element to be sucked in and that caused a MAF to be destroyed by contaminants): 1) first signs of issue before 43,000 miles (when check engine light and/or LHM happened -repaired 18sep2023, 51,871 miles, MB service code: LI14.20-N-073867); 2) 26 DEC 2023 - EGR failure diagnosed and replaced by MB dealer. Cleaning had not fixed the issue or failure was final as found by driving by technician and not by codes! 3) 09/jul/2024 - MAF replaced, EGR codes noted - but functioning, fix by MB/Canada 4) 07/24/2024 - 70,547 miles - EGR Clean by MB Missoula MT - failed upon highway same day 5) 07/25/2025 - 70,600 miles - MB Missoula MT cleared computer 6) 88,340 MB cleaned EGR - runs ok again

Sudden complete engine failures occurred in my Mercedes-Benz Sprinter van during highway operation while transporting freight, creating a serious safety hazard due to immediate and total loss of engine power in active traffic conditions. The first engine failure occurred at approximately 303,000 miles. The second failure occurred at approximately 140,000 miles after engine replacement. In both cases, there were no prior warning signs, diagnostic alerts, abnormal noises, or performance issues before sudden and catastrophic engine shutdown. Both incidents occurred while I was operating the vehicle at highway speeds during commercial freight delivery. The engine failed without warning, resulting in immediate loss of propulsion while in traffic. On both occasions, I was forced to rapidly maneuver the disabled vehicle to the shoulder under reduced control and arrange emergency towing to safely remove the vehicle from the roadway and prevent a potential collision or injury. These failures created a significant highway safety risk due to the abrupt loss of power while merging, traveling in traffic flow, and operating at speed. A sudden engine shutdown in these conditions could result in a rear-end collision, loss of control, or multi-vehicle accident, particularly in high-speed or heavy traffic environments. The repeated nature of catastrophic engine failure following engine replacement raises concern about a potential underlying defect in the engine system, components, or related assemblies, or possible unresolved mechanical or installation-related issues. The recurrence of identical failure conditions under similar operating circumstances increases concern that this may not be an isolated incident. Vehicle Information: Mercedes-Benz Sprinter used for commercial freight delivery First engine failure: ~303,000 miles Second engine failure: ~140,000 miles (replacement engine) Failure type: Sudden, complete engine shutdown with no warning at highway speed

I had 5 recalls completed at the MB Sprinter dealership in Pleasanton CA on 11/06/2025. Had hardly driven it 100 miles or 5 times since then when I noticed it was not always going into park. One recall had to do with not going in park when you push park button while foot on brake. I was not having that problem until the MB Sprinter dealership did the recall work. Now every 5th time or so it does not go in park when I push park button while foot on brake. Dealership insists I must pay to have this fixed even though their recall work caused it. This is a severe safety hazard that could result in death!

Driving at speed (70-75 mph) in the HOV lane of the I-5 Freeway south of Los Angeles, a warning signal would occasionally light up and sound when the van passed under HOV signage indicating HOV exits. Then, with a completely clear lane ahead – no vehicles, no obstacles – the van's braking system activated just before the van reached one of these overhead signs. The brakes fully locked, the van skidded briefly before the brakes released. The driver of the car following behind slammed on his/her brakes to avoid rear-ending the van. A very dangerous situation and major accident was only avoided because the traffic was relatively light in that particular section of the freeway at that time of day.

Serpentine belt shredded, cooling fan separated from clutch, pulley screws missing and pulley completely freed from mount and loss of power steering. This seems very similar to previous recall which my vehicle was supposedly not impacted by. Losing power steering in a large vehicle like this is extremely dangerous. Loose components in engine bay has potential to cause more problems. Fan and pulley completely free to come off and fly around bay. This problem has been seen by 10+ Revel owners in the last few weeks. This topic is being openly discussed on public forums and social media. It is currently sitting at MB of Littleton in Littleton, CO and has yet to be inspected. There were no warnings.

BOUGHT VEHICLE 26 SEP 20 FROM GENERAL RV IN DRAPER, UTAH I WAS INFORMED OF THE WINNEBAGO REVEL 2ND ALTERNATOR RECALL NUMBER 162 HAD TO BE COMPLETED BEFORE I DROVE THE VEHICLE OFF THE LOT. SO, I WAS TOLD [PER MANAGER MIKE MALLORY] IT WAS COMPLETED ON OCTOBER 10TH AND THUS DROVE IT OFF THE LOT ON OCTOBER 22ND, 2020. FAST FORWARD FOUR MONTHS TO FEB 2021 AS STARTED TO NOTICE A GOD-AWFUL SQUEALING SOUND WHEN I STARTED THE VEHICLE NO MATTER WHAT TEMPERATURES AND IT HAS PROGRESSIVELY GOT WORSE UP UNTIL APRIL NOW. ON 8 APRIL 21 WHILE AT A MERCEDES-BENZ DEALER IN FARMINGTON, UT I WAS TOLD THE SECONDARY ALTERNATOR WAS OUT OF ALIGNMENT AND THE ONE AND ONLY SERPENTINE BELT HAD EXCESSIVE WEAR, PLUS THE ISSUE WAS NOT A MERCEDES-BENZ WARRANTY ISSUE,, BUT RATHER A AN UP-FITTER (WINNEBAGO) PROBLEM PER MECHANIC TREVOR AND SERVICE REP ALEX! SO, ON 9 APR 21 I CONTACTED GENERAL RV AGAIN & SAID WHAT THE MERCEDES DEALER TOLD ME AND ON THE 22ND OF APRIL I PROVIDED PHOTOS OF THE ALTERNATOR ISSUE, SO THEY (PAUL DELUCA LEAD SVC REP) ORDERED THE RECALL KIT #162 FROM WB. HOWEVER, HERE'S THE REAL KICK IN THE FACE AKA COMPLAINT... WHY WOULD THEY NEED TO ORDER ANOTHER RECALL KIT WHEN THEY TOLD ME THEY STALLED IT IN OCTOBER 2020 BEFORE I COULD EVEN DRIVE IT OFF THE LOT? THEREFORE, GENERAL RV FLAT OUT LIED TO ME WHICH IS UNBELIEVABLE AND TOTALLY UNACCEPTABLE ESPECIALLY WITH THE SEVERITY OF A SERPENTINE BELT FAILURE AT SPEED EQUALS LOSS OF STEERING AND CRASH AND/OR DEATH NO TO MENTION TOTALLED VEHICLE! SECOND ISSUE/COMPLAINT IS MY ACTIVE BRAKE AND DISTANCE SENSOR BEHIND THE GRILL HAS BEEN RANDOMLY FAILING ESPECIALLY AT THE WORST TIMES I.E. LONG ROAD TRIPS! SO, THIS RENDERS THE CRUISE CONTROL & SMART BRAKING INOPERABLE WHICH IS UNACCEPTABLE ON A NEW VEHICLE WITH ONLY A FEW THOUSAND MILES ON IT. SO, I HAVE BEEN TO THE SAME MB DEALER IN FARMINGTON, UT 3NOR 4 TIMES TO FINALLY FIX IT, BUT NO FIX!!

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.

The windshield wipers are malfunctioning. They randomly turn on after using the blinkers. I cannot get them to turn off unless I turn off the vehicle. I'm afraid they will begin to fail completely and eventually not turn on. This will be a safety issue when it rains. I took the vehicle to the Mercedes-Benz dealership and they were able to reproduce the problem. They said the windshield wiper module in the steering wheel needs to be replaced. It is available for inspection upon request. There were no warnings, messages, or symptoms of the problem prior to the failure. They first appeared 9/18/2023. I also called several third-party Mercedes mechanics and they said this is a common problem with Mercedes.

The contact owns a 2020 Mercedes-Benz Sprinter 2500. The contact stated while driving 60 MPH, the passenger’s sideview mirror started rattling, making it difficult to see out the mirror. The vehicle was taken to the dealer and the housing of the mirror was pushed back into place; however, the failure persisted. The manufacturer was not contacted or notified of the failure. The failure mileage was 700.

The wiring harness under my front passenger swivel seat became pinched and severed the wires. The air bag warning light came on. I took the vehicle to the dealer and got it fixed at my own expense. I noticed the recall #21V410000 which is for the same thing, however my van was not included. Can my van be included so I can be reimbursed by the mfg?

Upon starting the engine to leave camp spot in middle of nowhere, the awning motor started extending outward on it's own very loudly and extended all the way. It would not go back in. Had to manually crank the awning in and noticed a bolt and nut not attached to anything in the railing where the awning is attached. Since the awning was not secured to drive on the freeway, used zipties to secure. Very unsafe as I was driving through high winds. I hopped on the forum for Winnebago Revels and immediately found several other instances of the same scenario happening with their Carefree awning. Never had any issues prior.

Drivers seat belt buckle steel cables that secure it broken, one completely in half. SRS light activates intermittently. I am 160lb male and have in no way contributed to this failure. This vehicle has under 12,000 miles on it and has barely used. This is clearly a safety violation
