Known issues on the 2019 MDX. Five recalls are on federal record for this model year: moisture entering the tailgate lid lights, where loss of the taillights reduces visibility and increases the risk of a crash; two separate fuel pump recalls, where fuel pump failure can cause an engine stall while driving; an internal engine hard-part defect, where a damaged engine may run improperly or stall while driving, increasing the risk of a fire or crash; and timing belt tooth separation, which may result in an engine stall. Owners have filed 288 complaints and Acura has issued 112 technical service bulletins for the year. This manual carries the factory diagnostic and repair procedures behind each of those systems.
From a scheduled service interval to a fuel pump replacement or a timing belt job, it keeps you on the OEM procedure and the correct specification for your specific 2019 MDX.
