2015 Mercedes-Benz Sprinter 2500

The Office of Defects Investigation (ODI) analyzed complaint data provided by Daimler Vans USA, LLC (Daimler) as well as complaints submitted to ODI from consumers to identify incidents related to Rear Wheel Speed Sensors (RWSS) failures. ODI's analysis identified 6,710 incidents of RWSS failure (unique VINs) in MY 2012-2018 Mercedes- Benz and Freightliner Sprinter vehicles upfitted to campers or recreational vehicles (RVs) representing 81 percent of all Sprinter RWSS reports. Complaint and warranty analysis indicated that the majority of incidents (approximately 99%) were related to RWSS moisture intrusion condition in the Sprinter 3500 5-ton variant, which accounts for 98 percent of upfit campers, where moisture build-up and crystal dendrite formation develop in parked RVs and lead to sensor failures. According to the Daimler Information Request (IR) response, if the wheel speed information is detected as implausible by the Electronic Stability Program (ESP) control unit, the ESP system enters a failsafe mode where:-Driver torque requests are no longer accepted;-Cruise control, if used, would be deactivated; -The ESP/ABS system shuts off; and -Multiple warning lamps and messages advise the operator to take the vehicle to the workshop. While the majority of reports involved only ABS and/or ESP warning lights and messages on the instrument cluster due to faulty sensor signals triggering a failsafe mode, some reports cited intermittent sensor failures resulting in increased vehicle speed while in cruise control and degraded ABS or ESP. Degraded ESP functionality may impact driving stability of the 5-ton vehicle.On Feb 3, 2021, following discussion with ODI, Daimler submitted a Defect Information Report (DIR) to NHTSA describing a defect in the RWSS disabling the ESP control unit functions in approximately 48,667 MY 2012 through 2018 Mercedes-Benz and Freightliner Sprinter 3500 vehicles manufactured from Jan 4, 2012 through Oct 25, 2018 (Recall 21V-042). In its DIR, Daimler indicated that RWSS sensor failures are prevalent in camper vans due to sustained periods of non-use, during which time the moisture may not dry out, remaining inside the plastic housing package. If the moisture within the RWSS dries and the RWSS returns to normal operation, the failsafe mode and the warning lights will disappear at the next ignition cycle, but the sensor fault remains stored within the ESP control unit and can be accessed through a diagnostic evaluation. ODI will continue to monitor field experience in Sprinter non-RVs and Sprinter 2500 RVs 3-ton and 3.5-ton variants (approximately 626 vehicles).Daimler will notify owners of the recalled vehicles and advise them to take their vehicle to a Mercedes-Benz or Freightliner Sprinter dealer, who will replace the RWSS with a repackaged sensor with high robustness against moisture intrusion. Daimler began notifying dealers and owners in Feb 2021. This Preliminary Evaluation is closed.The ODI reports cited above can be reviewed at NHTSA.gov under the following ID numbers:11352380 11351299 11350521 11348969 11342776 11342464 11341988 11341151 11340388 11338230 11337921 11331832 11331829 11331476 11331427 11331066 11328671 11325768 11325693 11322814 11322346 11320295 11319376 11317336 11311647 11310621 11308318 11254223 11253828 11252220 11196530 11194330 11164250 11145019 11141273 11139000 11138785 11124129 11094122 11394837 11390889 11390039 11389262 11387883 11387713 11386418 11383887 11383866 11382947 11377384 11376615 11376973 11375781 11375403 11374997 11374151 11373892 11373111 11366293 11365920 11365594 11365355 11365194 11364253 11364346 11363990 11363787 11362948 113629

one or more of the rear-wheel speed sensors may experience an electrical failure, which potentially could lead to a disablement of the Electronic Stability Control (“ESP”) control unit functions. If ESP control unit functions are disabled, vehicle driving stability may be impacted under certain driving conditions, increasing the risk of a crash.

The contact's employer owns a 2015 Mercedes-Benz Sprinter 2500. The contact stated that when the vehicle was started in the morning, there was a small puddle of fuel pooling under the fuel tank lid. The contact was not aware of any warning light being illuminated. The contact had taken the vehicle to an independent mechanic who diagnosed the vehicle and determined that the leak was from the fuel filler neck and the fuel filler neck needed to be replaced. The vehicle was not repaired. The contact researched online and related the failure to NHTSA Campaign Number: 17V092000 (Fuel System, Diesel). The manufacturer was informed of the failure and informed the contact that the vehicle was not included in the recall. The contact was transferred by the manufacturer to the NHTSA Hotline. The failure mileage was approximately 180,000.

For about a year occasionally when I put my van in park it rolls away mostly within approx.5 seconds thankfully all the times this happened I was able to jump back in to hit the brake pedal. I told the dealer the problem about 1 month ago they looked into it and said they could not find any problem.Yesterday for the first time my van rolled out of park approx.3 minutes later and collided with my other vehicle.I was able to see this happen and the time it took to roll away in park do to the fact I have video surveillance.I am at this point putting a chock behind the tire til I can figure out what to do.

Two separate incidents where wheel speed sensors failed. One in June 2022; one in September 2023. This disables antilock braking (ABS), electronic stability control (ESC), forward collision warning (FCW), brake force distribution and cruise control. Almost all safety features are disabled. Previously a safety recall has been implemented for the 5 ton Mercedes Sprinter model (3500), for these same faulty wheel sensors. Service for these Sprinters is difficult to schedule when traveling with an upfitted Class B (Roadtrek) RV like ours. The sensors are covered for replacement with our 10-year extension warranty for the emissions system, but only after failing. This places the driver + occupant (s) at risk until an available service center can be found and an appointment scheduled. Please issue a safety recall so we can have our remaining 2 wheel speed sensors replaced prior to failure.

Complaint While driving through muddy / sandy/ off road terrain "4Matic Currently Unavailable" message on the dash Cause This vehicle is not equipped with a fixed force distribution AWD, rather force is only applied to the front axle according to ESP calculations. As per GF28.00‑D‑ 9900A: "vehicles with 4MATIC all‑wheel system and variable force distribution, an electronically regulated multiplate clutch integrated into the transfer case provides for the torque distribution. If the multiplate clutch is open during normal driving operation, only the rear axle drives the vehicle. If the clutch is closed, the front axle comes into play." The message "All‑wheel drive temporarily unavailable" is not indicative of a malfunction but rather informs the driver that all‑wheel drive is currently not available due to the transfer case clutch overheating. This occurs when the vehicle is driven in such a way that maximum front axle torque is needed for an extended period, causing the clutch to get excessively hot. If the vehicle is being driven under heavy load conditions, like in deep sand or snow, the rear axle may slip while the front axle does not deliver power. The transfer case then attempts to distribute torque to correct the slip, but it is limited to a maximum of 1150 Nm to protect the front axle transmission. In extended heavy‑load scenarios, the multidisk clutch in the transfer case slips, increasing the temperature. If the temperature model detects a critical temperature of 240°C, the system protects itself by disconnecting until it cools down to around 160°C, after which the all‑wheel drive becomes available again and the warning message disappears.Vehicles can handle flat terrain easily, but steep slopes or situations where wheels slip might cause additional resistance, leading to the described protection events and message in the dash. Remedy Recommendation is to release the vehicle back to the client with an explanation that the vehicle is operating as designed. Please advise the client to limit vehicle acceleration in limited traction situations to avoid disabling of the 4Matic system ‑ please see "Notes on all‑wheel drive" provided in the operators manual.

ASSYST PLUS service reminder appears earlier than expected due to vehicle operating conditions Complaint The ASSYST PLUS service reminder appears earlier than expected. The customer or dealer may report that the vehicle did not reach the starting maintenance interval shown in vehicle documentation, option coding, sales literature, or the Owner's Manual. The service reminder may appear significantly earlier than anticipated even though no faults are stored and no malfunction is present in the vehicle. The remaining distance and remaining time continue to decrease normally until the service reminder is displayed. Cause This condition is not caused by a malfunction of ASSYST PLUS. ASSYST PLUS is a dynamic maintenance management system that continuously evaluates vehicle usage and opera-ting conditions to determine maintenance requirements. The starting maintenance interval specified by variant coding represents a maximum interval that may only be achieved under favorable operating conditions. Actual maintenance intervals may be significantly shorter depending on vehicle use. Vehicle operating conditions such as driving conditions, engine load, engine operating conditions, idling, short-trip operation, environmental influences, oil aging, and Diesel Particulate Filter (DPF) regeneration activity may reduce the maintenance interval from its starting value. These conditions may accelerate engine oil aging through increased soot loading, fuel dilution, moisture accumulation, and additional engine operating stress. As a result, the remaining distance and remaining time until the next service may be reduced from the starting maintenance interval. Remedy Do not replace any parts. A due service must be assumed if the maintenance data calculated by ASSYST PLUS indicates that service is required.

NOTE: This LI supersedes LI14.20-N-073813, which is no longer valid. Cause Cause of Complaint A: Increased friction between the EGR Valve blade and seat due to soot deposits causing a delay of the EGR Valve being able to reach the target value of the EGR Valve position controller. NOTE: This causes the EGR Valve blade and potentially the boost pressure controller to oscillate. Cause of Complaint B: Soot deposits between the EGR Valve blade and seat leading to the EGR Valve no longer being able to meet the de-sired target of the EGR Valve position controller. Cause of Complaint C: Internal EGR Valve or other electrical faults related to the EGR Valve function. Remedy Remedy for Complaint A: Perform the following steps: 1. Disable the EGR Valve (Y27/17) by disconnecting the electrical connector. 2. Perform a test drive to check if the jolting/bucking issue resolves. 3. If the jolting/bucking is resolved, proceed to Remedy for Complaint B. 4. If jolting/bucking is still present, proceed with diagnosis to determine the root cause. Consider checking the follo-wing, but not limited to: •EGR system including the EGR Cooler, EGR Bypass Flap, EGR Temperature Sensor, and pipes for proper operati-on, excessive sooting and/or clogging, as well as EGR Bypass Flap vacuum element, switchover valve, and vacuum system. •Visually check the leak oil line or T-piece; reference LI07.00-N-059118.
