IMPORTANT

---------

"This bulletin is a revision of Pontiac Product Campaign Bulletin 90-C14, dated April 1994. This bulletin is being revised to expand the VIN breakpoints under the "VEHICLES INVOLVED" and additional wheel disc codes have been added to the "SERVICE PROCEDURE" section. Please discard all copies of bulletin 90-C-14".

TO: ALL PONTIAC DEALERS

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 Pontiac 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 INVOLVED

General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1988-90 Pontiac Grand Prix model vehicles equipped with steel wheels (RPO's PB9 (14") and PG1 (15")). These vehicles may exhibit a condition in which cracks develop in the wheel mounting surface and, should the cracks become severe enough, the wheel could completely separate from the vehicle. If this were to occur while the vehicle was in motion, steering and braking control of the vehicle could be affected, and a vehicle crash could result without prior warning.

To prevent this condition from occurring, dealers are to inspect the manufacturing date codes stamped on each wheel to determine if the wheels were produced during a suspect period. Whenever a wheel falls within the specified date code range, dealers are to replace that wheel assembly.

VEHICLES INVOLVED

Involved are certain 1988-90 Pontiac Grand Prix model vehicles built within the following VIN breakpoints: Up To And Year Plant Beginning Including ---- ----- --------- --------- 1988 Fairfax JF239499 JF286357

1989 Fairfax KF200001 KF249798

1990 Fairfax LF234909 LF272945

The listing included with this bulletin only contains the VIN's of the vehicles added to the campaign with this revision. Please refer to your month end reports for complete VIN list.

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

OWNER NOTIFICATION

Owners will be notified of this campaign by Pontiac Division (see copy of Owner Letter included with this bulletin).

DEALER CAMPAIGN RESPONSIBILITY

All unsold new vehicles in dealers' possession and subject to this campaign must be held and inspected/repaired per the Service Procedure of this campaign bulletin before owners take possession of these vehicles.

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.

Owners of vehicles recently sold from your new vehicle inventory with no owner information indicated on the dealer listing, are to be contacted by the dealer, and arrangements made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such owners a copy of the owners letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the owner may not as yet have received the notification letter.

In summary, 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, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.

PARTS INFORMATION

Parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). To ensure these parts will be obtained as soon as possible, they should be ordered from GMSPO on a "C.I.O." order with no special instruction code, but on an advise code (2).

If codes match any of the combinations listed in the chart or are unreadable/illegible, the wheel must be replaced.

4. Repeat above procedure for remaining three wheels on vehicle.

5. As required by inspection, replace necessary wheels (& balance). Use torque stick J395444-15 and impact gun to tighten lug nuts to appropriate torque.

This should be done in two steps using the star pattern. First, snug the nuts down by hand. Then using the star pattern and a torque stick or torque wrench, tighten the wheel nuts to about half the final torque. Finally, tighten the wheel nuts to specification using the star pattern and the torque stick/wrench. Use the same amount of impact wrench operating time a would normally be used without a torque stick.

6. Render all removed wheels unusable and scrap as required by campaign procedures.

7. Install Campaign Identification Label.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
