Known issues on the 2021 Sprinter 2500. Eighteen recalls cover the 2021 Sprinter 2500. One affects gasoline versions only: on certain vans the fuel pump could shut down and cut drive power, and dealers replaced it. A paint problem drove another, where the topcoat formula on certain vans could keep windows and interior lashing rails from bonding securely, so either might break loose in a crash. Certain vans could also have a partition wall missing bolts. Electrical faults and forward collision avoidance tie at the top of the 45 complaints with 9 each, service brakes follow with 7, and 2 complaints reported a crash and 1 an injury.
