NHTSA lists 1 safety recall and 89 owner complaints for the 2006 Buick Rendezvous. Most complaints involve electrical system (21) and suspension (14). The EPA rates it 18–19 mpg combined.
CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
