2020 Mercedes-Benz Sprinter (vs30)

The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) opened this PE after receiving 11 Vehicle Owner Questionnaires (VOQs) alleging that Model Year (MY) 2019 Mercedes-Benz (MB) Sprinter vans, configured for use as Amazon delivery vehicles or ambulances, roll away shortly after being shifted to park using the Auto-P function. A rollaway vehicle with no operator behind the steering wheel could potentially strike pedestrians, moving or parked vehicles or buildings, resulting in injury, fatality and/or property damage. Analysis of data provided by MB in response to the ODI Information Request (IR) letter showed a high failure rate. Following discussions with ODI about the failures, MB decided to conduct a safety recall. On December 15, 2021, Daimler Vans USA, LLC filed recall 21V-972 covering 48,400 model year (MY) 2019-2020 Mercedes-Benz (MB) Sprinter vans. With recall 21V-972, this investigation is closed. The affected vehicle population determined by MB is Sprinter vehicles (VS30, Platform 907) produced between June 5, 2018 and November 30, 2020 with a manual parking brake and a 7-speed automatic transmission that was manufactured between May 1, 2018 and October 31, 2019, in the Hedelfingen transmission plant in Germany.Further use of Agency resources does not appear to be warranted. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist on other model or MY vehicles outside of the recall scope. The agency reserves the right to take further action if warranted by the circumstances.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers:11360500, 11404893, 11404894, 11360505, 11404417, 11405798, 11405804, 11404969, 11404838, 11404891, 11415509, 11428353, 11428296, 11298470, 11428219, 11405803, 11427068, 11428216, 11428296, 11429905, 11447877, 11452051

When the object proximity sensors in the front or rear bumpers detect an object, the vehicle completely or severely limits the throttle. For instance, the rear bumper sensors detect the bike rack attached to my van and therefore limit the throttle response, regardless of transmission direction (forward or reverse). This seems to happen intermittently. When I mute the bumper sensor’s warning by tapping a button, then the throttle responds as expected. This is a known problem on the 2019+ VS30 Mercedes Sprinters, which affects all vans; it is not isolated to my specific van. This presents a safety issue, when the driver expects the vehicle to move but it does not. For instance, when rolling into traffic yet the throttle does not respond.

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.

Oil Leak at Crankcase Near the High-pressure Fuel Pump OM654 Complaint Visible oil leak at the crankcase near the mounting area of the high‑pressure fuel pump on OM654 engines. Cause Oil leakage near the high‑pressure fuel pump may result from insufficient sealing performance of the jump shaft seal and/or reduced sealing effectiveness at the interface between the high‑pressure fuel pump and crankcase. Relative movement of the high‑pressure fuel pump within the crankcase bore may reduce sealing effectiveness at the pump‑to‑crankcase interface and promote oil migration during engine operation. Remedy Install a new high‑pressure fuel pump together with the design‑optimized sealing ring.

Model 907 with all-wheel drive (A4M) – All-wheel drive inoperative Complaint The customer may report one or more of the following: • All-wheel drive is unavailable or inoperative. • Rear wheel slip during acceleration on low-traction surfaces. • Noise from the front axle area while driving. • Message in the instrument cluster indicating all-wheel drive is unavailable due to overheating. • Fault code P27874B - The temperature of the clutch is too high. There is a fault due to overtemperature may be stored in control unit N15 (Transfer Case). Cause An internal failure of the front axle differential may result in loss of torque transfer to the front wheels. In some cases, a fracture of the weld between the crown gear and differential housing may be present. Remedy Replace the front axle differential in accordance with: AR33.30-D-0525TSY – Replace Front Axle Differential.

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.

Fuel Level Unchanged After Refueling Complaint The customer reports that the fuel gauge shows inaccurate readings or remains unchanged after refueling. Cause A. The Fuel Supply Control Unit (FSCU) fails to detect a refueling event B. The Fuel Level Sensor provides incorrect readings due to mechanical interference or installation issues

Complaint Complaint A: The engine is jolting/bucking between 1700 and 1900 rpm. Complaint B: One or more mechanical related fault codes for EGR Valve stored in CDI control unit, with possible Check Engine Light. Review list of mechanical fault codes in table below. NOTE: If one or more electrical related fault codes for EGR Valve are also present in CDI, utilize Complaint C. Review list of electrical fault codes PDF document in attachments. Complaint C: One or more electrical related fault codes for EGR Valve stored in CDI control unit, with possible Check Engine Light. Review list of electrical fault codes PDF document attached. 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.
