CAMPAIGN:PARKING BRAKE LEVER MAY NOT HOLD-REPLACE. Buick Skyhawk 1987

MODELS AFFECTED: 1987 SKYHAWK

CONDITION

General Motors has determined that certain 1987 Buick Skyhawk models fail to conform to the requirements of Federal Motor Vehicle Safety Standard 105, "Hydraulic Brake Systems." These vehicles might have been assembled with parking brake lever mechanisms which will not properly engage when applied.

In some of these vehicles, the parking brake can be applied and appear to be properly engaged and later, when the vehicle is unattended, it could disengage. If the transmission were neither in gear (manual transmission) nor in Park (automatic transmission), the vehicle could unexpectedly roll. In such an instance the vehicle might roll away uncontrolled, which could result in a vehicle crash without prior warning.

DEALER ACTION

To correct this condition, dealers are to replace the parking brake lever assembly as outlined in the Technical Procedure section of this bulletin.

VEHICLES INVOLVED

Certain 1987 Skyhawks within the following serial numbers:

Assembly Plant From Through & Including

Leeds (K) HK400001 HK400731

NOTE: Some of the subject vehicles within the breakpoints listed above were corrected at the assembly plant prior to being shipped to the dealer and will not require correction by the dealer. All subject vehicles which are listed on the dealer's campaign printout will require correction, as outlined in the Technical Service Procedure Section of this bulletin. Should a question exist concerning the campaign involvement of a specific vehicle(s) within the breakpoints listed above, dealers should call the Computerized Recall Infomation System) for verification.

DEALER CAMPAIGN RESPONSIBILITY

Dealers are to service all vehicles involved in this campaign at no charge to owners regardless of mileage, age of vehicle, or ownership, from this time forward.

This bulletin is notice to you that the new motor vehicles included in this campaign may not comply with the standard identified above. Under Sections 108 and 114 of the National Traffic and Motor Vehicle Safety Act, it is illegal for a dealer to sell a new motor vehicle which the dealer knows does not comply with an applicable Federal Motor Vehicle Safety Standard. As a consequence, if you sell any of these motor vehicles without first performing the campaign correction, your dealership may be subject to civil penalty up to $1,000 for each such 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 be sure the campaign correction has been made before reselling or releasing the vehicle.

Owners of vehicles recently sold, from your new vehicle inventory, are to be contacted by the dealer, and arrangements made to make the required modification according to instructions contained in this bulletin.

If your dealership has vehicles involved in this campaign, you will receive the following items:

- List of all vehicles involved in this campaign shipped to your dealership. - One (1) Parking Brake Lever Assembly tagged for Campaign 87-C-1 for each vehicle on your listing. - One (1) Campaign Identification Label for each vehicle.

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

Dear Buick Owner:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

In some of these vehicles, the parking brake can be applied and appear to be properly engaged and later, when the vehicle is unattended,it could disengage. If the transmission were neither in gear (manual transmission) nor in Park (automatic transmission) the vehicle could unexpectedly roll. In such an instance, the vehicle might roll away uncontrolled, which could result in a vehicle crash without prior warning.

Always be sure that your transmission is placed in Park position if you have an automatic transmission, or Reverse if it's equipped with a manual transmission. This will assist in preventing the vehicle from rolling when parked.

To correct this condition on your vehicle, please contact your Buick dealer to arrange a service date to have the parking brake lever assembly replaced. This service will be performed at no charge to you.

Instructions for making this correction have been sent to your Buick dealer. The labor time necessary to complete the correction is approximately 35 minutes. Please ask your dealer if you wish to know how much additional time will be necessary to process your vehicle.

Your Buick dealer is best equipped to provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date and your vehicle's condition is not remedied on that date, or within five days, we recommend that you contact the Customer Assistance Department, Flint Home Office by calling 800-521-8350.

If you are still not satisfied that we have done our best to remedy this condition, without charge, within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street, S.W., Washington, DC 20590; or call 1-800-424-9393 (Washington, DC residents use 426-0123).
