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 copy of the letter which is being sent to owners, the owner is being instructed to contact the
GMC Truck Division Consumer Relations 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 1993 K 10703 pickup trucks (short wheel base
half-ton 4-Wheel Drive) may have been built with one-piece rear prop shafts having tube to yoke welds off location. In this condition, the attachment of
the front and/or rear yoke to the prop shaft tube may not withstand normal driveline torque inputs causing the tube to separate from the yoke. If the tube
were to separate from a yoke while the vehicle was moving, the prop shaft could cause damage to the underbody sheet metal of the cab, or possibly
detach from the vehicle.
To prevent this condition from occurring, dealers are to inspect the vehicles to determine if a Saginaw Three Rivers plant prop shaft was installed and, if
so, replace it.
VEHICLES INVOLVED
Involved are CERTAIN 1993 Sierra K 10703 pickup trucks built at Fort Wayne Assembly. The involved vehicles are listed as shown.
