Known issues on the 2007 CLS550. The federal record holds four recalls for the 2007 CLS550 and the roof glass is at issue in them. On certain cars the adhesive holding the glass panel to the sliding roof frame can break down, and in related campaigns the glass sunroof panel on certain vehicles may not be fixed securely; either way the glass could come off and land in traffic. Dealers inspect the bonding and replace the panel or the sliding roof as needed. Fuel delivery dominates the 34 complaints, with 17 under fuel/propulsion and 8 under the gasoline fuel system. Sliding roof and fuel system procedures are covered.
