Known issues on the 2009 E550. The sliding roof is the recurring subject. NHTSA recorded three recalls for this model year, each involving certain 2009 E550 vehicles in which the glass roof panel could come adrift from its frame, through failing adhesive or improper securing, and become a hazard on the road. Dealers checked the bonding and replaced panels or complete roof units as necessary. Owners lodged two complaints about this car, one about wheels and one about the gasoline fuel system; separately, two complaints filed against the 2009 E-Class line involve the electrical system and fuel and propulsion. Roof, fuel system and wheel procedures are covered in the manual, with torque values and wiring diagrams.
