2020 MERCEDES BENZ SPRINTER 2500 Forward Collision Avoidance Problems

The adaptive cruise control, auto emergency breaking and collision warning stopped working on the vehicle on a clear day as I was entering the freeway for a long drive. It said sensors were dirty. I stopped, shut off vehicle, cleaned all sensor locations, and restarted vehicle. Sensors worked for 5min and then stopped again and have yet to start functioning after 4 days and extensive driving. It appears that this is a common issue for other 2019+ Sprinter owners. This definitely reduces the safety of the vehicle for the driver, passengers and other vehicles. Shut-off without warning, reduces speed unexpectedly in traffic is a risk. The distractions of looking down for solutions to see what's going on and trying to reset system.

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.

crosswind assist randomly kicking in, acting in a dangerous manner. Vehicle swirl, almost fish tailing. Other times it randomly slams on the brakes, slows down by 10mph, almost got rear ended.

Cross wind assist kick on for random reason, not able to disable this feature. It slams on the brake dropping my speed by 10MPH with vehicle almost rear ending me. At times it steers the vehicle in such a way that it almost fish tail.

Adaptive Cruise Control as well as Forward Collison warning fail to work properly when in use. Both unexpectedly malfunction for no apparent reason and vehicle will not cruise control will not function at all. The vehicle was taken back to the dealership where it was supposedly addressed and fixed, however, the issue has not been fixed. The vehicle presents the same issues as prior to the inspection and "repair" from the dealership. While driving with Adaptive Cruise Control/Forward Collison Warning, the system will malfunction. A light on the dash will indicate that it has been disabled, simultaneously, the vehicle will lose cruise control, foward collision warning immediately. Vehicle will not regain any form of cruise control or forward collison warning for an unspecified amount of time. Could be minutes, hours, or even days. Dash warnings also include cleaning sensors and cameras. Doing so does not correct the problem.

The cruise control system and related systems (distance control and automatic braking) repeatedly malfunction. Specifically the systems go off and on without warning. For example, when driving at highway speed the systems will suddenly shut off causing the vehicle to slow down (presumably without brake lights to alert the driver behind). Also presumably the automatic braking ceases to work when this happens This problem began shortly after I purchased the vehicle in May 2021 and I have brought it in for three unsuccessful repair attempts. Internet research reveals that this is apparently a common problem.

The adaptive cruise control system and forward collision system since the vehicle was new has frequently not worked or stops working. The cruise control system that is tied to the forward collision systems would stop working causing the vehicle to decelerate as no throttle input was present and cause the need to use the foot throttle. The vehicle is available for inspection. As this has happened while driving at freeway speeds with traffic around I consider this a hazard. This problem has been present since the vehicle was new and continues to the present time even after dealership fixes. The dealership is aware of this problem and initially tried to “ recalibrate the sensors “ with no success, and finally found that the wire connectors were not connected properly. Since this fix was performed the cruise control has continued to turn off primarily if minimal forward traffic is sensed, but proceeds to reset either later the same day or the following day. As the vehicle his under warranty and has not been involved in an accident the only people who have seen it are the dealership. The vehicle will give two warnings at the time of the system failing 1.”Active Distance Assist Inoperative “, and 2. “Active Brake Assist Functions Limited See Owners Manual”. For the dates and mileage listed below this issue has been present with the vehicle since new to current as an intermittent issue so the dates and mileage do not represent the actual events. Having looked at van blogs on this issue this is an common problem with owners of vans and other Mercedes vehicles with the radar adaptive cruise control referred to as “Distronic “

The contact owns a 2020 Mercedes-Benz Sprinter 2500. The contact stated that after inclement weather, the cruise control, Forward Collision Avoidance, and Automatic Emergency braking feature failed to operate as needed. The contact restarted the vehicle however, the vehicle would intermittently return to normal operation. The contact had taken the vehicle to various different dealers where the camera, unknown sensors, and other unknown parts were replaced; however, the failure persisted. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 10,000.

cross wind assist too sensitive, kicking on randomly causing more mouvement than if it wasn't doing anything. Wind would normally move me sideways about 6" and this thing moves me by 2', slams on the brakes, slows down when trucks are in my ass. The swing it gives when kicking on with side winds lifted 2 wheels in the air and also did a couple tire marks on asphalt from blocking wheels.

Cross wind assist if really dangerous. Very little cross wind and it hit the brakes really hard, the van fish tails and slows down so much people will rear end me. Date is last time it happened but it's been doing this since we got this vehicule. Very well know problem across many Sprinter owners. There's currently no way to disable this feature for the driver. Also have an older sprinter without this feature and it's unnecessary.

On July 7, after driving a half hour late morning, we stopped to tour Skyline Caverns, Front Royal, VA. Parked in the shade. The vehicle was turned off for 90 minutes. Starting up, the following warnings began displaying: -- Active Lane Keeping Assist Inoperative -- LOW RANGE Malfunction - To Park, Apply Parking Brake -- ESP® (Electronic Stability Program) Inoperative -- Active BAS (Brake Assist System) Functions Limited. See Operator's Manual. -- Blind Spot Assist Inoperative -- Active Distance Assist DISTRONIC Inoperative. Looked up items in the owner's manual. Accessed the MBUX on-line manual. Accessed the Assistance menu. Malfunctioning systems showing as "Function Unavailable". Called MB Roadside Assistance. They said vehicle drivable, but must be careful. Asked about the "LOW RANGE Malfunction" -- after the support person consulted with others, all uncertain about the impact highway driving would have on the "LOW RANGE Malfunction". Authorized tow to Euro Motorcars Bethesda Sprinter, 9030 Comprint Ct, Gaithersburg, MD 20877 Tel: 301-652-9000 / 301-881-5160. After the vehicle was parked at Comprint Ct after the tow, the same warnings continued to appear. I don't believe the dealer's mechanics were able to start working on the problem until July 12 at which time the warning messages were no longer appearing. Dealer has been unable to replicate malfunction. Mechanic supervisor drove vehicle 100 miles over the weekend of July 17 without replicating malfunction. Vehicle currently at Comprint Ct. Received NHTSA Recall #21V411 on July 24; the above described Malfunctions may be related to this recall.

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!!

WHILE DRIVING ON A HIGHWAY AND PASSING UNDER A ROAD SIGN DESCRIBING THE NEXT EXIT, THE SPRINTER VAN AUTOMATIC CRASH AVOIDANCE KICKED IN, CAUSING THE VAN TO AUTOMATICALLY JAM ON THE BRAKES AND LOSE APPROXIMATELY 20 MPH WHILE CAUSING THE WHEEL TO PULL DECIDEDLY TO THE LEFT. THERE WERE NO VEHICLES IN FRONT OR BEHIND, AND THANKFULLY ENOUGH NONE CLOSE ENOUGH TO CAUSE AN ACCIDENT. THIS IS A FAIRLY COMMON OCCURRENCE, AND EVEN IF THE BRAKES DO NOT ENGAGE, THE CRASH AVOIDANCE ALERT SOUND WILL OFTEN TIMES CHIME AND STARTLE THE DRIVER FOR OTHER OVERHEAD OBSTACLES LIKE TRAFFIC SIGNS AND TUNNEL ENTRIES. THIS FEATURE, ALONG WITH LANE DEPARTURE ASSIST (WHICH ALSO IS BUGGY) AUTOMATICALLY TURNS ON AFTER EVERY RESTART, EVEN AFTER BEING TURNED OFF MANUALLY. IT IS UNSAFE.
