On certain trucks and sport utility vehicles, the driver wishing to signal a turn by moving the directional signal lever, (up or down) may cause the front marker/turn lights and rear turn lights to flash in a manner similar to hazard warning, rather than flashing on the desired side only.

The driver may not be able to clearly signal their intentions to turn, change travel lanes, or potentially warn others of an impaired vehicle operating condition increasing the risk of a crash.

Dealers will replace the suspect flasher modules with a new flasher module designed with sealed relays and more durable contact material inside of the relays. The recall is expected to begin during August 2005. Owners should contact GMC at 1-866-996-9463.
