CAMPAIGN:REAR COMPARTMENT PAN WELDS

SUBJECT: REAR COMPARTMENT PAN SIDE RAIL WELDS

YEAR: 1994

MODEL: ACHIEVA

TO: All Oldsmobile Retailers

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle 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 included copy of the letter that is being sent to owners, the owners are being instructed to contact the Oldsmobile Customer Assistance Network (OCAN) if their retailer 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 certain 1994 Oldsmobile Achieva vehicles may not comply with Federal Motor Vehicle Safety Standard (FMVSS) 301, "Fuel System Integrity". These vehicles may have been built with welds in the rear compartment pan assembly which do not meet General Motors' manufacturing standards. As a result, these vehicles may not meet the FMVSS standard relating to fuel leakage in the event of a rear-impact crash. To prevent this condition from occurring, retailers are to install rivets adjacent to the locations where suspect welds may have occurred.

VEHICLES INVOLVED

Certain 1994 Oldsmobile Achieva models within the following VIN breakpoints:

YEAR MODEL MODEL NAME VIN BEGINNING THROUGH & INCLUDING

1994 N ACHIEVA RM036409 RM038311

Most of the subject vehicles within the breakpoints listed above were corrected at the assembly plant prior to being shipped to the retailer and will not require correction by the retailer. All subject vehicles which are listed on the retailer's campaign printout will require correction as outlined in the SERVICE PROCEDURE section of this bulletin.

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 retailers with the campaign bulletin. Owner name and address data furnished will enable retailers 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 retailer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

PARTS INFORMATION

Each involved retailer will be preshipped on, July 21, 1994, the required number of parts equal to 50% of the number of vehicles to be repaired (minimum of one set per included retailer). Preshipped parts will be charged to the retailer's open account.

If additional parts are required to complete this campaign, they 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 ).

OWNER NOTIFICATION

Owners will be notified of this recall on their vehicles by Oldsmobile Division (see copy of the owner letter included with this bulletin).

RETAILER CAMPAIGN RESPONSIBILITY

This bulletin is notice to you that the new motor vehicles included in this campaign may not comply with the standard identified. Under Section 301 of the National Traffic and Motor Vehicle Safety Act, it is illegal for a retailer to sell a new motor vehicle which the retailer 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 retail facility may be subject to a civil penalty up to $1,000.00 for each such sale.

All unsold new vehicles in retailers' possession subject to this campaign mus be held and inspected/repaired per the service procedure of this campaign bulletin before owners take possession of these vehicles.

Retailers 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 retailer listing are to be contacted by the retailer, 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 included in 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 retail facility 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. Your cooperation in completing this campaign as soon as possible will be greatly appreciated.

Dear Oldsmobile Achieva Owner:

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

REASON FOR RECALL: General Motors has determined that certain 1994 Oldsmobile Achieva vehicles may not comply with Federal Motor Vehicle Safety Standard (FMVSS) 301, "Fuel System Integrity". These vehicles may have been built with welds in the rear compartment pan assembly which do not meet General Motors' manufacturing standards. As a result, these vehicles may not meet the FMVSS standard relating to fuel leakage in the event of a rear-impact crash.

WHAT WE WILL DO: To prevent this condition from occurring, retailers are to install rivets adjacent to the locations where suspect welds may have occurred. This service will be performed for you at no charge.

WHAT YOU SHOULD DO: Please contact your Oldsmobile retailer as soon as possible to arrange a service date. Instructions for making this correction have been sent to your retailer and parts are currently available. The labor time necessary to perform this service is approximately 1.3 hours. Please ask your retailer if you wish to know how much additional time will be needed to schedule and process your vehicle.

Your Oldsmobile retailer is best equipped to obtain parts and provide service to ensure that your vehicle is corrected as promptly as possible. If, however, you take your vehicle to your retailer on the agreed service date, and they do not remedy this condition on that date or within five (5) days, we recommend you contact the Oldsmobile Customer Assistance Center by calling 1-800-442-OLDS.

After contacting your retailer and the Oldsmobile Customer Assistance Center, if you are still not satisfied that we have done our best to remedy this condition without charge and within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street, S.W., Washington, D.C. 20590 or call 1-800-424-9393 (Washington D.C. residents use 366-0123).

The enclosed owner reply card identifies your vehicle. Presentation of this card to your retailer will assist in making the necessary correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid reply card and returning it to us.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your safety and continued satisfaction with our products.

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.
