Known issues on the 2023 GLB250. The 2023 GLB250 is part of one recall. It concerns certain vehicles in which corrosion could affect a small switch in the driver's door lock, leaving the car unaware the door is open; without that signal the parking brake or Auto-Park feature may fail to engage, and a rollaway becomes possible. The repair is a replacement door lock. Owners submitted ten complaints for this year, with the engine named four times and the power train twice. The manual's diagnostics and wiring diagrams cover the engine and power train.
