NHTSA (USA)Medium Risk
This page covers 18 recalls and 44 owner complaints for the 2021 Mercedes-Benz Sprinter 2500.
The dominant complaint pattern for the 2021 Sprinter 2500 centers on driver assistance systems behaving unpredictably. Owners most frequently report problems with forward collision avoidance and lane departure features, describing false activations, unexpected braking, and interventions that feel abrupt or poorly calibrated. A related thread runs through several reports about the crosswind assist system engaging too aggressively on highways, owners describe the vehicle suddenly yawing or slowing without warning, with no straightforward way to disable or reduce the system's sensitivity. Powertrain complaints make up the next notable group, though at lower volume, with owners describing general drivability concerns. A smaller number of reports mention a hood latch failure where the hood released while driving and struck the windshield, though that appears in only a handful of accounts.

By System
The 2021 Mercedes-Benz Sprinter 2500 has 18 recalls, the most serious involving a front suspension torsion bar that can fail at its connection point, causing sudden loss of vehicle stability and raising the risk of a crash.
Two electrical wiring recalls also carry fire risk: a cable duct inside the battery case can drop and allow the starter-generator wiring to chafe against the transmission carrier, and a generator wiring harness can be incorrectly connected to the power steering system, both of which can cause an electrical short or surge and start a fire. Separately, the fuel pump can shut down without warning, cutting drive power while the vehicle is moving.
On the structural side, several recalls involve fasteners and bonding. The partition wall may be missing bolts and can break free in a crash, windows and interior lashing rails may not be adequately bonded and can detach in a collision, frame members may be missing reinforcement fasteners that affect stability and third-row seat integrity, and rear step bolts may be loose enough that the step can fall off and become a road hazard. A brake hose can be worn by contact with the fender liner, causing brake fluid to leak and extending stopping distances. On vehicles equipped with swivel seats, wiring routed through the seat frames can be damaged and cause the seat-mounted side airbag to deploy unexpectedly or fail in a crash. The parking pawl on vehicles with a 7-speed automatic transmission and manual parking brake can wear and fail to hold the vehicle in place, allowing it to roll away.
