This page covers 22 recalls and 12 owner complaints for the 2020 Mercedes-Benz Sprinter 3500.
Complaints for the 2020 Mercedes-Benz Sprinter 3500 are spread thinly across a small number of reports, with no single system drawing an overwhelming volume. Brakes, electrical behavior, and forward collision avoidance each account for a small cluster of reports. On the electrical side, owners describe sudden dashboard flickering, multiple simultaneous warning messages, and accessories like windshield wipers activating on their own with turn signals going unresponsive. On the safety system side, owners report a "Brake Assist Inoperable" warning appearing and persisting for miles before clearing on its own, with dealer visits pointing to a sensor issue. A couple of owners note that forward collision avoidance features have been unreliable or nonfunctional for extended periods, with parts availability cited as a barrier to repair.

Crash-Related
By System
The 2020 Mercedes-Benz Sprinter 3500 has 22 recalls, with the most serious concerns involving brake failure, an unintended rollaway risk, and a driveshaft that can loosen and puncture the fuel tank in a crash, raising the risk of fire.
On the brake side, rear calipers can leak fluid into the electric parking brake housing, letting air into the hydraulic system and causing the pedal to travel further before the brakes engage. Front and rear brake hoses can also develop leaks over time, reducing braking performance and directional stability. A separate issue can cause brake lights to stay on even when the pedal is not pressed. The park lock software may allow the vehicle to creep after being shifted into Park, and on manual-parking-brake models with a 7-speed automatic, the transmission's parking pawl can fail to engage, also allowing rollaway. Fuel line clamps can loosen and cause a fuel leak, adding another fire risk independent of the driveshaft issue.
Structurally, the frame may be missing reinforcement fasteners that affect stability and third-row seat integrity in a crash, and the partition wall may be missing bolts and can break free in a collision. Front door hinges may have loose screws, and the power steering return line can detach suddenly, leaving the driver with heavy, unassisted steering. On vehicles with a swivel seat, wiring routed through the seat frame can be damaged, causing side airbags to deploy unexpectedly or fail in a crash. The optional electric sliding door may carry the wrong auxiliary lock
