Known issues on the 2022 G550. Fuel delivery links the recall and complaint records for this year. The three recalls naming certain 2022 G550 vehicles include two for a fuel pump liable to stop running and cost the vehicle its drive power, and both owner complaints concern the gasoline fuel system. The remaining recall covers certain vehicles that got a replacement right rear door latch at a service visit or in an earlier recall repair, where parts inside that latch could stop the rear doors closing or opening properly. The manual's fuel pump diagnostics and door latch procedures cover these systems.
