Daimler Vans USA has issued a recall for no fewer than 20,500 workhorses, including the Freightliner-branded Sprinter. The vans in question were produced for the 2021 and 2022 model years with fuel delivery modules that may shut down unexpectedly while driving.
An increasing number of fuel pump shutdown reports prompted Mercedes to investigate said condition back in June 2022. After sourcing defective fuel delivery modules from the field, the Stuttgart-based automaker concluded that mechanical resistance made these fuel pumps fail. A deformed fuel pump impeller ultimately comes into contact with the fuel delivery module's housing, leading to a loss of propulsion.

South Korea-based Hyundam Industries Co. is the supplier of said pump, yet said company bears only half of the blame for this problem. The folks at Hyundam discovered an irregularity with the raw material used by a secondary supplier for impeller production. It's also worth noting that Hyundam implemented production process changes without informing Mercedes of them, which is a big misstep in the automotive industry.

Merc is aware of no fewer than 330 warranty claims, service reports, and field reports of fuel pump failure. Said claims and reports were received in the period between January 25, 2022 through May 23, 2023.

Hyundam and the secondary supplier implemented changes in the production process for the fuel delivery module in December 2022. As for the affected vehicle population, make that Sprinter and Metris vans built from April 21, 2021 through December 23, 2022.

Daimler Vans USA informed the National Highway Traffic Safety Administration that affected vehicles will have their fuel delivery modules replaced at no charge to the owners. The dealership network will be informed of this recall on July 21, while owner notifications will be made via first-class mail on July 28.

Better known as V-Class or Vito, the Metris launched in the United States and Canada for model year 2016 back in 2015. It and the Sprinter are assembled in Ladson, South Carolina. Not long now, this plant will also assemble the eSprinter for the North American market.

As implied, the eSprinter makes do without internal combustion. A rear-mounted electric motor in two states of tune is the name of the game, with Mercedes quoting 100 and 150 kW (134 and 201 horsepower). Both versions are joined by a 113-kWh battery, which offers up to 400 kilometers (249 miles) in the WLTP.

The Worldwide Harmonized Light Vehicle Test Procedure isn't as close to real-world range as EPA's way of determining range, though. Those who prefer good ol' internal combustion are presented with 3.0-liter turbo diesel V6 oomph. The 2.0-liter turbo gasser I4 was discontinued only recently. Mercedes will also discontinue the Metris after the 2023 model year due to poor demand.

At press time, the Sprinter carries a sticker price of $49,900 for the cargo van. The crew van is $52,120, the passenger van $55,800, and the cab chassis $53,000.
