I removed the drive side seat belt bolt in order to remove the pillar it is mounted to and found the bolt extremely hard to turn and ultimately somewhat stripped upon removal. The bolt remains defiant in re-installation procedure. The passenger side was removed without stripping but did attempt to cross-thread itself upon re-installation which was remedied by simple hand threading. Safety put at risk in that these seat belt bolts and their installation process may not restrain passengers in an accident. Not confirmed by dealer or service center - pictures should be self evident. The component hasn't been inspected by any party - I'm just going to buy a new bolt and re-tap the hole it was installed in. No warning lights for this isssue.

2024 Mercedes-Benz Sprinter 2500 experienced unusually rapid brake, tire, and battery wear at low mileage. Front brakes required replacement at approximately 29,000 miles. Rear brakes were already worn low by approximately 37,000 miles. Rear tires required replacement by approximately 37,000 miles. Vehicle battery also failed and required replacement before approximately 37,000 miles. Vehicle had earlier emissions/sensor related repairs as well. This creates safety concerns because premature brake wear can reduce stopping ability and increase stopping distance. Premature tire wear can reduce traction, especially in rain, and increase risk of tire failure or blowout. Unexpected battery failure can disable the vehicle without warning in traffic or roadside conditions. Vehicle is used in normal commercial delivery service and is generally not heavily loaded. I have owned and operated multiple prior Sprinter vans over many years, and previous model years achieved substantially longer brake, tire, and battery life under similar or heavier use. A newer comparable fleet vehicle with similar mileage has not required these repairs. The issue appears abnormal compared with prior ownership experience and may indicate brake system drag, an alignment issue, defective components, battery charging issue, or another unresolved defect. Vehicle has been serviced by dealer and components were replaced, but premature wear remains the concern. In addition, rear brake wear occurring this early suggests possible imbalance or excessive brake application that should be investigated. Rapid tire wear combined with brake wear may indicate alignment or braking system issues affecting vehicle control and safety. I am submitting this complaint so the condition can be reviewed for potential defect trends affecting other similar vehicles. Defective parts may be available from prior repairs depending on service center retention.

Vehicle: 2024 Mercedes-Benz Sprinter VIN: [XXX] Mileage: 148,000 The vehicle is experiencing a serious safety-related defect where the starter motor remains engaged even after the engine is turned off. This results in the starter continuing to run and stay powered, which can cause severe mechanical damage, overheating, and presents a potential fire risk. The starter has already been replaced, but the issue persists, indicating the problem is within the vehicle’s electrical control system (such as wiring harness, relay, or control module). Additionally, I was informed that this same vehicle had a prior wire harness-related issue in 2024 under the previous owner, suggesting a recurring or unresolved electrical defect. This condition can lead to unexpected vehicle behavior and poses a safety hazard due to the risk of electrical failure or fire. The vehicle is currently at a Mercedes-Benz dealership for diagnosis, and a case has been opened with Mercedes-Benz USA under case #XXX. I am submitting this complaint to report a potential safety defect and request investigation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Complaint Description I am filing this complaint with the National Highway Traffic Safety Administration regarding a safety issue with my new Mercedes Benz Sprinter 2500. I purchased this vehicle brand new from Mercedes Benz Manhattan. From the first day of ownership, I began experiencing multiple serious problems with the van. The main issue is that exhaust smoke and/or crankcase gases enter the cabin while driving. In addition, the vehicle experiences strong vibrations and the transmission frequently kicks or shifts abruptly. On several occasions this issue has caused the engine to stall while driving. (Traffic light stop) These problems create a potentially dangerous situation and make the vehicle unsafe to operate. The dealership, Mercedes Benz Manhattan, has attempted to repair the vehicle many times, but the problems persist and have not been resolved. Because of the ongoing safety risks, I believe this issue should be investigated.

Yes the wind assist in my opinion is more dangerous than dealing with the wind itself. No safe!

The van has a cross wind assist mode. When it activates it aggressively activates only one front wheel brake so dramatically that the van dives down and swerves out of the lane into the adjacent lane. The front wheel happened to be on wet pavement and it was chattering from braking so hard and not getting traction. I passed a slower motorcycle on the road and the crosswind assist almost caused me to run him off the road. The problem has not been reported to the dealer because i have read on several forums that dealers wont do anything about it. many people are complaining about this and it happens without warning. the problem started as soon as I bought the van, it now has 10,000 miles on it. This is a feature that is included with the van. When the dashboard lights do come on when the cross wind assist activates. No other warnings nor is thier any warning before the wind assist activates. Thanks for reading my concern

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.

Complaint The check engine light is activated, accompanied by one or more of the following fault codes related to the Boost Pressure Positioner: • P300A6D The boost pressure is too low. Charge Air Cooler. • P300974 Component 'Boost pressure positioner' has a malfunction. The boost pressure is too low. • P300DFB Component 'Boost pressure positioner' has a malfunction. • P300DE8 Boost pressure control A has a malfunction after the cold start. Cause The potential causes for these fault codes are: A. Leak or Blockage in the Intake or Charge Air System: This can prevent the proper flow of air, affecting the boost pressure. B. Insufficient Source Vacuum, Vacuum Leak, or Sticking/Weak Vacuum Component: These issues can prevent the boost pressure positioner from functioning correctly. • For Model Year 2023-Cuurent vehicles operating at approximately 4,000 ft elevation or above, reduced ambient pressure and/or high brake demand may contribute to reduced available vacuum differential and under boost com-plaints, even when no discrete vacuum component failure is identified. C. Internal Malfunction of the Boost Pressure Positioner: The component itself may be faulty. D. Internal Defect with the Variable Turbine Geometry (VTG) System inside the Turbocharger: Issues within the turbo-charger can affect boost pressure control. Remedy Engineering Review Required: For vehicles operating at approximately 4,000 ft elevation or above, a TIPS case MUST be opened before replacing any component for fault codes P300A6D, P300974, P300DFB, or P300DE8.

Complaint The customer reports that the engine cranks but does not start, or only starts after extended cranking. A check engine light may be present, and fault codes P300616 (The fuel pressure in the system is too low) and/or P300617 (The fuel pressure in the system is too low) may be stored, along with other fuel pressure-related fault codes. Cause Insufficient high-pressure fuel build-up during engine cranking. The fuel system does not achieve the required rail pressure of >120 bar, preventing engine start. This condition may be caused by internal leakage within the fuel injection system, inadequate fuel supply from the low-pressure circuit, or a malfunction of the high-pressure fuel pump. Remedy 1. Verify high-pressure fuel rail pressure during engine cranking using XENTRY actual values. • Evaluate the actual value “The starter turns and the combustion engine does not start” and monitor high-pressure fu-el rail pressure during cranking. (See attachment: XENTRY actual values – rail pressure not reaching >120 bar) • The system must achieve a minimum of >120 bar in order to enable engine start. → If the specified rail pressure is not achieved, perform the following checks: 2. Check low-pressure fuel supply • Verify fuel quality (color, clarity, separation, contamination) • Inspect fuel tank, fuel filter, and low-pressure fuel pump for debris, restriction, or damage • Measure low-pressure fuel supply before and after the fuel filter and confirm values are within specification • Perform a fuel volume test at the high-pressure pump inlet to ensure adequate delivery • Verify that the injector leak line is installed correctly, remains unmodified, and is not restricted or kinked → If low-pressure fuel supply is not within specification: Repair as necessary and recheck high-pressure fuel build-up 3. Check for internal leakage within the fuel injection system • Perform a fuel injector leak/return test using XENTRY • Evaluate injector leak-back during cranking NOTE: If the combustion engine does not start, perform the test by cranking the engine 3–4 times for approximately 15 seconds each, instead of allowing the engine to run for approximately 60 seconds → If injector leakage is present: Replace the affected injector(s) and perform injector teach-in 4. Check high-pressure fuel system • If no leakage is identified and low-pressure supply is sufficient, evaluate high-pressure fuel generation → If high-pressure fuel system does not generate sufficient pressure: Replace the high-pressure fuel pump 5. Final verification • Verify that rail pressure exceeds >120 bar during cranking • Confirm the engine starts normally without extended crank • Clear fault codes and perform final validation

Complaint The customer reports an exhaust odor from the engine compartment, potentially accompanied by a check engine light and/or engine misfire. Cause The injector hold-down may fracture due to material-related factors, allowing the injector to lift from its seat and resulting in combustion gas leakage past the sealing interface. Remedy Carry out repair measures in accordance with the extent of damage determined during inspection. Replace only tho-se components identified as faulty or compromised by the failure, including the fuel injector, sealing ring, injector hold-down, hold-down bolt, high-pressure fuel line(s), and, if required, the fuel distributor (rail). All work involving fuel injector removal and installation must be carried out in accordance with WIS document AR07.16-D-1020TSM. Particular attention must be given to the proper preparation of the injector bore and sealing in-terface. All carbon deposits, combustion residue, and surface contamination must be fully removed to ensure correct injector seating and sealing integrity, thereby preventing combustion gas blow-by and repeat failure.
