Known issues on the 2004 Canyon. The brake lamp circuit accounts for two of the three recalls on this truck's federal record: a fault that either kills the stop lamps outright or leaves them burning continuously, taking the cruise control with it on trucks so equipped. The remaining one covers standard and extended cabs built with a front split bench and no rear seat, where the top tether anchor needed to secure a child restraint could not be reached. Owners have logged 80 complaints, clustering on suspension, body structure and the electrical system, which are the areas this manual's chassis specifications and wiring diagrams address.
