Known issues on the 2019 RLX. Three recalls are on federal record for this model year: two for gasoline fuel-pump delivery, where a fuel pump failure can cause the engine to stall while driving and increase the risk of a crash, and one for the engine timing belt, where teeth separating from the belt may result in an engine stall and increase the risk of a crash. No owner complaints are on file for the year, and 12 technical service bulletins have been issued. The factory diagnostic and repair procedures behind each of those systems are here.
From a routine service interval to a fuel-delivery diagnosis or a timing belt job, it keeps you on the OEM procedure and the correct specification for your specific 2019 RLX.
