Known issues on the 2021 Sprinter 3500. The 2021 Sprinter 3500 has 16 recalls on the record. Paint chemistry caused one: the top layer of paint on certain vans could weaken the bond holding windows and cargo lashing rails in place, so either could come loose in a crash, and in badly affected cases the company could offer to buy the van back. Cluster lighting in certain vans could not be turned down and was too bright to read in some conditions, and certain vans might be missing frame fasteners that support the third-row seats. Suspension leads the 7 complaints at 3, and 1 complaint reported a crash. Body, instrument cluster and frame procedures and diagnostics are covered.
