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

Check engine light with fault code P300E5F and/or P300E5E in MRD1 (CDI) Complaint The check engine light is on, with a possible reduction in power. No soot is present in the exhaust system. Fault codes: P300E5F ‑ The fill level of the Diesel Particulate Filter is too high. Early warning. P300E5E ‑ The fill level of the Diesel Particulate Filter is too high. Regeneration of the Diesel Particulate Filter is disabled. Additional information: No additional fault codes related to the Diesel Particulate Filter or Exhaust Gas Recirculation system may be present for this LI to apply. Cause These fault codes may be triggered due to unfavorable driving conditions, such as: •Frequent short‑distance trips •Extended idle periods •Infrequent highway driving •Incomplete regeneration cycles These conditions can lead to excessive soot accumulation in the Diesel Particulate Filter, resulting in elevated fill levels and regeneration lockout. Remedy Fault code P300E5F indicates that the Diesel Particulate Filter soot load has exceeded 130% but remains below 160%. Regeneration remains permitted. Fault code P300E5E indicates that the Diesel Particulate Filter soot load has exceeded 160%. Regeneration is disabled to protect components. 1. Perform a tailpipe wipe test Inspect the tailpipe for soot using a clean white cloth. • If soot is found, stop this procedure and follow LI49.20‑N‑078466. • If no soot is found, continue with Step 2. 2. Check the Diesel Particulate Filter data Using XENTRY, review and save the following information: • Diesel Particulate Filter fill level • Calculated soot load • Ash load • Regeneration history • Distance and operating time since the last successful regeneration • Relevant exhaust‑temperature and differential‑pressure actual values Process any additional fault codes according to the applicable Guided Tests before attempting regeneration. 3. Perform a manual standstill regeneration Perform a manual standstill regeneration of the Diesel Particulate Filter according to the current XENTRY instructions. • Save or print the regeneration results. 4. If the manual standstill regeneration completes successfully Clear the fault memory and verify that the Diesel Particulate Filter actual values are plausible. • Confirm that the applicable fault codes do not return. • Complete a road test and confirm that no fault codes return. • Use damage code 14370F7 if the vehicle is under warranty. Release the vehicle only after proper Diesel Particulate Filter operation has been confirmed. 5. If the manual standstill regeneration does not complete successfully Replace the Diesel Particulate Filter according to the current Workshop Information System instructions. • Confirm that the MRD1/CDI control unit has the latest available software. Update the software if it is not current. • Thoroughly inspect the exhaust system downstream of the Diesel Particulate Filter for soot. • If soot is found, follow LI49.20‑N‑078466 for the required inspection and replacement of affected components. • Complete all required teach‑in, initial startup, and reset procedures after the repair. • Clear the fault memory and perform a road test. • Recheck the fault memory and verify that the Diesel Particulate Filter actual values are plausible.

Check engine light with fault code P3005CA in MRD1 (CDI) Complaint The check engine light is on, with a possible reduction in power and the presence of soot in the exhaust system. Fault code P3005CA: The diesel particulate filter efficiency is insufficient. Additional information: Additional fault codes may be present, related to the Diesel Particulate Filter (DPF) system or the Exhaust Gas Recirculation (EGR) system. Cause This fault code sets due to the following factors: 1. Damage to the Diesel Particulate Filter (DPF) unit. 2. The N74 Soot Particulate Sensor Control Unit detects soot or debris downstream of the underbody SCR catalytic converter. Remedy Note: The XENTRY guided tests for fault code P3005CA have been revised. Complete all applicable guided tests before replacing components. TIPS cases are no longer required unless: • No soot is found at the Diesel Particulate Filter (DPF) outlet. • The fault occurs on a vehicle produced after the applicable production clean point. • The fault returns after the applicable repairs have been completed. • The fault occurs on a vehicle confirmed to have the latest available MRD1/CDI control unit software.

Check engine light with reduced power with fault codes P300A6D, P300974, P300DFB, or P300DE8 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. • P300A6F: The boost pressure is too low. (High‑pressure turbocharger) • P300A71: The boost pressure is too low. (Low‑pressure turbocharger) • 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 a 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 proper airflow, affecting 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‑Current 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 underboost complaints, 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 turbocharger can affect boost pressure control.
