CAMPAIGN: SPLASH SHIELD CONTACTS BRAKES HOSE
MODELS: 1988 K 15-25 PICKUP TRUCKS
The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequately repair within 60 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 owner 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 solutions, every effort must be made to promptly schedule appointments with owners and to repair their vehicles as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owner is being instructed to contact the nearest GMC Zone Office if the dealer does not remedy the condition within five days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed how to contact the National Highway Traffic Safety Administration.
DEFECT INVOLVED
General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1988 K 15-25 pickup trucks. These vehicles may have the fender skirt splash shields contacting the front brake hoses. This contact can cause wear on the brake hoses, eventually resulting in a failure of the front hydraulic brake system. When this failure occurs, the rear brake system still functions, but increased stopping distances will be required. Loss of front braking at a time when minimum stopping distance is required could result in a vehicle crash without prior warning.
To correct this condition, it will be necessary to modify the fender skirt splash shield and replace the brake hose on both sides.
VEHICLES INVOLVED
Involved are certain 1988 K 15-25 pickup trucks built within the following VIN breakpoints:
MODEL ASSEMBLY YEAR PLANT FROM THROUGH ---- ----- ---- -------- 1988 Ft. Wayne JZ500026 JZ500362

DEALER CAMPAIGN RESPONSIBILITY
Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward. Dealers are to correct all affected vehicles in new and used vehicle stock prior to their sale.
Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service in the future, you should take the steps necessary to ensure the campaign correction has been made before reselling or releasing the vehicle.
