Known issues on the 2015 TLX. Three recalls are on federal record for this model year: a gasoline fuel-pump failure that can cause an engine stall while driving, increasing the risk of a crash; an internal engine hard-part defect that can make a damaged engine run improperly or stall while driving, increasing the risk of a fire or crash; and an automatic transmission control-module recall tied to insufficient crimps in the transmission wire harness, where an unexpected shift to neutral increases the risk of a crash. Owners have filed 531 complaints for this year, and 225 technical service bulletins have been issued. This manual carries the factory diagnostic and repair procedures behind each of those systems.
From a routine service interval to a fuel-delivery diagnosis or a transmission harness fault, it keeps you on the factory procedure and the correct specification for your specific 2015 TLX.
