NHTSA (USA)Medium Risk
The 2021 Mercedes-Benz Sprinter 4500 has 16 recalls, the most serious being a front suspension torsion bar that can fail and cause sudden loss of vehicle stability, and a wiring harness that can chafe against the transmission and short-circuit, raising the risk of a fire.
Several recalls involve structural and chassis integrity. A partition wall may be missing bolts and can detach in a crash, becoming a hazard to occupants. The rear step can also separate from the vehicle if its fasteners were not properly tightened, creating a road hazard. On the braking side, the front fender liner can contact and wear through the brake hose, causing fluid to leak and extending stopping distances. The parking pawl in the 7-speed automatic transmission can wear and fail to hold the vehicle in place, allowing rollaway. Longitudinal frame members may be missing reinforcement fasteners, which can reduce stability and allow third-row seat mountings to fail in a crash. Windows and interior cargo rails may also be poorly bonded and can detach in a collision.
On the safety equipment side, swivel seat wiring can be damaged by the seat frame and cause side airbags to misfire or fail, and seat belt retractors can deactivate early and fail to properly secure a child safety seat. Several electrical recalls cover a rearview camera that can display a black screen when reversing, an instrument cluster that can go completely blank at startup, instrument brightness that cannot be adjusted, and an emergency call system that can lose its mobile connection and fail to reach emergency services.
