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.

The contact owns a 2024 Mercedes-Benz E Sprinter. The contact stated that while driving at 10 MPH, there was an abnormally loud sound coming from the passenger’s side of the vehicle. Several unknown warning lights were illuminated. The contact pulled over to the right side of the road and turned off the vehicle for an hour. The vehicle was then restarted and worked as intended; however, after the vehicle was parked in a public parking lot, several undisclosed electrical failures occurred. A dealer was contacted. The vehicle was towed to the dealer, and it was determined that the A-frame needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and referred the contact to the NHTSA Hotline to report the failure. The approximate failure mileage was 22,000.

The Rear Axle Drivetrain Assembly failed. Specifically, a critical structural fastener (bolt) associated with NHTSA Recall #25V090 (MBUSA #2025020010) completely detached from the rear axle. The vehicle is currently in my possession and the failed component/repair is photographed. The detachment of this structural bolt caused a complete loss of propulsion while the vehicle was in a commercial driveway. Had this occurred minutes earlier during my 500-mile round trip on the I-95 highway, it would have resulted in a catastrophic drivetrain separation or axle lock-up at highway speeds (65+ mph). This posed a fatal risk to myself, my passengers, and other motorists. The failure was confirmed and documented by an independent service center (Crown Auto, [XXX] ) and subsequently confirmed by an authorized Mercedes-Benz dealer (Mercedes-Benz of White Plains). White Plains issued a strict "Do Not Drive" order and dispatched emergency roadside assistance to transport the vehicle. The vehicle has been inspected by Mercedes-Benz of White Plains (authorized manufacturer representative) and Crown Auto. I have photographic evidence of the failed component prior to the re-repair. Mercedes-Benz of El Cajon (the originating dealer) has also been provided with photographic evidence but has refused to acknowledge the failure. No warning lamps or messages appeared prior to the failure. The first symptom was a complete loss of propulsion and a "spinning" sensation from the rear axle upon arriving in Queens. This lack of warning is particularly dangerous as the vehicle gave no indication of the impending structural failure during a 500-mile highway journey. The Service Director at the originating dealership, Ernie Serrano, initially denied the existence of the safety recall in writing and subsequently suggested that I misrepresent the nature of the failure to avoid a 'failed recall' record. This suggests a systemic attempt to hide safety-critical repair failures from the manufacturer a INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INF

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)
