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 repair within sixty (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 an appointment with each owner and to repair
their vehicle as soon as possible. As you will see in reading the attached copy of the letter that is being sent to owners, the owners are being instructed to
contact the Chevrolet Customer Assistance Center if their dealer does not remedy the condition within five (5) days of the mutually agreed upon service
date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.
Defect, Vehicles Involved, Owner & Dealer Information
DEFECT INVOLVED
General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1984 through 1988 Chevrolet vehicles equipped with
Cruise Control (RPO K34) on certain gasoline and diesel engines. A small nylon bushing in the cruise control servo bail (bracket) may slip out of place.
This will not affect the operation of the cruise control, but it may cause intermittent increases in engine speed or dieseling (engine run-on with ignition
off).
If the vehicle is not serviced and the nylon bushing remains out of place, the servo rod assembly could wear through the bail. If the rod wears through the
bail, it may catch on other engine components and possibly result in a stuck throttle. Although the vehicle can still be stopped with the service brake, an
unexpected loss of accelerator control could result in vehicle crash.
To prevent this condition from occurring, Dealers are to install a Bushing Kit on the Cruise Control Servo Bail. The cruise control servo assembly is not
authorized as a replacement to correct for a missing or out of place bushing. Also, if other repairs are needed to the cruise control system, and the vehicle
is out of warranty, the repairs would be at owner's expense.
VEHICLES INVOLVED
Involved are certain 1984-1987 Chevrolet vehicles equipped with Cruise Control (RPO K34) and engines (5.7L Diesel VIN code "N" or 5.0L Gas VIN
