2003 Isuzu Ascender RecallsRecall 05V494000
The turn signals may operate like hazard flashers when intending to signal for a turn. The driver may not be able to clearly signal their intentions, increasing the risk of a crash. Dealers will replace the suspect flasher modules with a new flasher designed with sealed relays for better durability. The recall began August 4, 2005. The GM recall number is 05044.
The windshield wipers may not turn on, turn off while in operation, or may not turn off. The windshield washer pump may operate continuously as well. Water in the wiper modules can cause a short circuit or can corrode the components in the module. Depending on the condition, this could cause reduced visibility, which could result in a crash. Dealers will replace the windshield wiper system assembly. The recall began on July 15, 2004.
