SERVICE INFORMATION
CONDITION
The manufacturer of your vehicle, General Motors, has decided that a defect, which relates to motor vehicle safety, exists in certain 2006-2007 Isuzu Ascender vehicles originally sold or currently registered in: Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin.
If fluid enters the drivers door module, it may cause corrosion that could result in a short in the circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. In rare cases, a short may cause overheating, which could melt components of the door module, producing odor, smoke, or a fire.
CORRECTION
Service Facilities are to test the driver's window and door lock switches for proper operation. If the switches function properly, Service Facilities are to inspect the module, and, if necessary, install a protective coating. If the switches do not function properly, Service Facilities are to install a new door module.
VEHICLES INVOLVED
Involved are certain 2006-2007 model year Isuzu Ascender vehicles.
Important:
Service Facilities are to confirm vehicle eligibility prior to beginning repairs by using the Isuzu Communication System (ICS).
For Service Facilities with involved vehicles, a listing of involved vehicles containing the complete vehicle identification number has been or will be provided. Service Facilities will not have a report available if they have no involved vehicles currently assigned.
SERVICE PROCEDURE

SERVICE FACILITY RECALL RESPONSIBILITY
It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.
The US 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 US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.
Service Facilities are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.
In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your for service in the future, you must take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.
