Known issues on the 2020 GLA250. Five recalls name this model year. Certain vehicles with a panoramic sunroof were recalled because a front roof panel reattached badly in a past repair could lose its adhesion and detach, becoming a hazard on the road; dealers fitted a new panel. On certain vehicles equipped with a gasoline engine, debris caught between the fuel rail and injectors during production could cause a fuel leak and a fire risk. The 9 owner complaints put electrical, power train and steering at the top with two each, and 1 complaint reported an injury. Fuel system, body and electrical procedures come with specifications and wiring diagrams.
