DATE:
August, 1987
SUBJECT:
CRUISE CONTROL CABLE LOCK MECHANISM
MODELS:
1988 C/K 15, 25 AND 35 TRUCKS EQUIPPED WITH CRUISE CONTROL (RPO K34)
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 some 1988 C/K 15-35 model trucks equipped with cruise
control (RPO K34). The cruise control cable lock mechanism may self-disengage. When this occurs, vibrations can cause the cable to readjust by itself
resulting in erratic cruise control operation or the throttle not retuming to idle. In this event, engine speed may not decrease to a level anticipated by the
operator.
Although the vehicle can still be stopped with the service brake, loss of accelerator control could result in a vehicle crash, without prior warning. To
prevent this condition from occurring it will be necessary to install a clamp around the lock tab of the cruise control cable on all involved vehicles.
