Service Information
Condition:
Isuzu Motors Limited has determined that a defect which relates to motor vehicle safety exists in certain 2002-2004 Rodeo, 2002-2003 Rodeo Sport, and 2002-2004 Axiom vehicles when operated with silicon-contaminated fuel. If a vehicle has been operated with silicon-contaminated fuel over a period of time, the resulting electrostatic discharge can cause pin holes to develop in the fuel pump feed port, through which fuel can leak. In some circumstances, a vehicle fire could result.
Isuzu has identified silicon-contaminated fuel in Texas. As a result, Isuzu is recalling the above mentioned vehicles registered in Texas and the four surrounding states: Arkansas, Louisiana, New Mexico, and Oklahoma.
Correction:
Dealers are to inspect and seal the fuel pump feed port. In some cases the fuel pump assembly may require replacement.
Dealer Responsibility
Isuzu dealers are required to service all eligible vehicles at no charge to the owner, regardless of mileage, age of vehicle or ownership.
Whenever a vehicle subject to this campaign is in a dealer's vehicle inventory, or arrives at the dealership for service, the dealer must take the necessary steps to ensure that this campaign correction has been made before selling or releasing the vehicle.
Each Isuzu dealer will be supplied a copy of the AIMI Campaign Report (AWS-123-1A) listing affected vehicles assigned to that dealership. The report contains VIN and detailed owner information obtained from state motor vehicle registration records. The use of such motor vehicle registration data for any other purpose is a violation of the law in several states. Accordingly, dealers are urged to limit the use of this listing to the follow-up necessary to complete this campaign. If none of the affected vehicles are assigned to a dealership, no campaign report will be sent.
The National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.
Owner Notification
Isuzu Motors America, Inc. will send a notification letter to owners of affected vehicles already retailed (Refer to copy of letter shown in this bulletin). Dealers should follow up with vehicle owners by sending a Campaign Reminder Notice (AIMI SVCF-1052) to all vehicle owners listed in the AIMI Campaign Report (AWS-123-1A). Dealers may obtain these postcards from Helm, Inc.
