Summary
The Mercedes-Benz Metris has 44 recalls spanning the 2015–2023 production run, with the most serious recent issue being a fuel pump shutdown on 2022–2023 models that can cut drive power without warning, leaving the vehicle unable to accelerate and raising the risk of a crash. The final production years also have a recall for right-hand-drive 2020–2023 vehicles where water can collect on the airbag control unit and prevent the airbags from deploying in a crash. The infotainment connections on 2020–2023 vehicles can work loose and cause the rearview camera image to go dark while backing up.
The 2021 model year has three occupant protection issues: the passenger seat frame may not be properly welded, reducing its ability to hold an occupant in a crash; the passenger seatbelt's automatic locking retractor can fail to lock when used to secure a child seat; and the rearview camera image may not appear at all when shifting into reverse.
The 2019 model year has a driveshaft attachment problem where the propeller shaft joint wears and produces vibrations that the airbag control unit can misread as a crash impact and fire the front airbags without warning. Head restraints on 2019 models may also be missing their retaining spring pins, allowing the upholstery carrier to separate from the housing in a crash.
The 2018–2019 power steering sensor can fail and suddenly drop steering assist, requiring significantly more steering effort. On 2017–2022 models, upper and lower fuel hose connections at the engine can come loose and leak fuel in the engine compartment, which creates a fire risk near an ignition source. The 2017–2018 driveshaft securing bolts can back out of the transmission flange, letting the shaft separate and cutting drive power entirely.
Going back to the 2016–2017 era, the fuel hoses around the underbody transition and fuel pump connections can weep fuel that may ignite, and the electric power steering control unit can lose contact due to corroded or poorly welded pins, abruptly dropping steering assist. On 2015–2017 models, the transmission support mounting can loosen and damage the driveshaft, and the power steering assist unit has a related contact-pin welding issue that can deactivate assist without warning.
The 2016 model year carries the most individual recalls of any year, including front seatbelt pretensioners that may not tighten in a crash, backup batteries without a protective cover that can short-circuit if a metal object falls into the seat base opening, a rear differential weld that can fail and cut power to the rear wheels, incorrect software applied during service that can interfere with stability control or airbag systems, and winter tires on some examples that may have been installed with an insufficient load rating.
