Known issues on the 2004 TSX. Four recalls are on federal record for this model year: hydraulic power steering hose and piping, where oil leaking onto a hot exhaust pipe will generate smoke and a burning smell; an engine and engine cooling fault, where a vehicle stall increases the risk of a crash; an accelerator pedal assembly that can bind, so the engine may not quickly return to idle after the pedal is released; and a tail light wire harness in the trunk hinge area that can be damaged over time, causing a blown fuse and a short circuit. Owners have filed 195 complaints and 58 technical service bulletins have been issued for the year. This manual carries the factory diagnostic and repair procedures behind each of those systems.
From a routine service interval to a power steering line replacement or a hard-to-trace harness fault, it keeps you on the OEM procedure and the correct specification for your specific 2004 TSX.
Dorman Products, Inc. (Dorman) is recalling certain Accelerator Pedal Assemblies part numbers 699-114 and 825-5029-1, sold as replacement parts for 2003-2006 Acura MDX, 2004-2008 Acura TL and TSX, 2003-2007 Honda Accord, 2005-2006 Honda CR-V, 2007-2011 Honda Element, 2005-2008 Honda Pilot and 2006-2014 Honda Ridgeline vehicles. The rotating portion of the accelerator pedal assembly may bind. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 124, "Accelerator Control Systems."
If the accelerator pedal binds, the engine may not quickly return to idle after the pedal is no longer pressed, increasing the risk of a crash.
Dorman will notify owners, and qualified service facilities will replace the affected accelerator pedal assemblies, free of charge. The recall began December 9, 2019. Owners may contact Dorman customer service at 1-800-523-2492, using option 5. Dorman's number for this recall is AS1019XXXX.
