Known issues on the 2020 RDX. Four recalls are on federal record for this model year: two separate gasoline fuel system delivery fuel pump campaigns, each because fuel pump failure can cause an engine stall while driving, increasing the risk of a crash; a front seat belt buckle assembly, where an unlatched seat belt cannot properly restrain the seat occupant during a crash; and a front passenger occupant classification air bag sensor, where an air bag that deploys unintentionally during a crash can increase the risk of injury. Owners have filed 418 complaints and Acura has issued 219 technical service bulletins for this year. This manual carries the factory diagnostic and repair procedures behind each of those systems.
From a scheduled service interval to a fuel delivery diagnosis or a supplemental restraint fault, it keeps you on the factory procedure and the correct specification for your specific 2020 RDX.
