2021 Mercedes-Benz Sprinter 2500 — Should You Buy One?
Typical asking price: $34,000–$52,000. There is 1 high-severity known issue you need to know before handing over a check.
Kestrel Take
The premium work-and-camper van — the Sprinter's tall interior, refinement, and efficient turbodiesel make it the gold standard for van builds and high-end delivery, which is why clean ones hold value strongly. The trade-off is real: Mercedes diesel service and emissions (DEF/DPF/EGR) upkeep are expensive, and you need a Sprinter-savvy shop. A documented, un-abused Sprinter is superb; a neglected diesel is a costly mistake.
What we checked
Partly reconciled against public records, 2026-09-11
NHTSA holds 270 owner complaints for the 2021 Mercedes-Benz Sprinter 2500, and no recall campaigns.
A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. The largest single group is electrics and electronics at 20%. That is notable without being overwhelming — worth checking, not worth panicking about.
Not written up yet: electrics and electronics (54 complaints), the driver-assist and automatic braking systems (54 complaints), the brakes (42 complaints). Those groups are in the public record and are not covered by the issues below. Treat them as something to ask about, not as absent.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
