Known issues on the 2004 TITAN. Seven recalls are on federal record for this model year. Front and rear lower control links can have collar welds that separate, degrading handling and raising crash risk. The engine control module relay in the intelligent power distribution module can develop silicon oxide on its contacts, causing engine stalling. Rear center seat belts on crew cab models may not release from the automatic locking mode once retracted, preventing their use. Certain aftermarket trailer brake control harnesses can misroute power to the dash light circuit instead of the trailer brakes, reducing stopping ability while towing. Wiring for the driver seat belt pretensioner, front passenger occupant classification system and rear speakers on king cab trucks can break from repeated door flexing, risking pretensioner misfire or a non-deploying passenger air bag. Column shift lever assemblies on certain pickups may be damaged during assembly, eventually failing to hold the lever in park. And an area on the rear pillar where the rear seat belt upper anchor attaches may not be sufficiently energy absorbent, raising injury risk in a crash. Owners have filed 1,046 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From tracing an ECM relay stall to inspecting a lower control link or a seat belt anchor point, it keeps you on the OEM procedure and the correct specification for your specific 2004 TITAN.
