1984 - 1991 Corvette: Recall: Left & Right Side Safety Belt Retractor Replacement

Estimated Reading Time: 17 Minutes

Source: Chevrolet Product Campaign
Number: 91C25 & 91C26
Model and Year: 1984-91 CHEVROLET CORVETTE

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. I f the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.


General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1984-91 Chevrolet Corvettes. Under specific conditions of vehicle operation and occupant usage, it is possible for the safety belts in these vehicles to lock-up or jam in the retractor. If this occurs, vehicle occupants will be unable to use the affected safety belt(s) because it will be impossible to pull the belt out of the retractor. In the event of a vehicle crash, unbelted occupants are more at risk of injury than those using safety belts.

If either safety belt in a Corvette exhibits this condition, dealers are to replace the affected retractor side safety belt. As this problem will not occur in all Corvette safety belts, only those safety belts which are experiencing a locked-up or jammed belt will require replacement under this recall.

Owners of involved vehicles are being instructed to retain their owner notification letter in case this condition should occur to their vehicle’s safety belt(s) in the future. Dealers are to provide a copy of the owner notification letter (included with this bulletin - reproduce locally) to future purchasers of any new or used inventory units so that these owners are aware that correction is available should this condition occur.

NOTICE: This campaign provides only for locked-up or jammed retractors to be replaced. To accommodate this situation, it has been necessary to issue two (2) campaign numbers (one for each safety belt: left side = 91C25 and right side = 91C26). Having separate campaign numbers assigned to each safety belt enables claims to be submitted at different times in those cases were only one safety belt requires replacement due to a locked-up or jammed condition. In these cases, a claim is to be submitted only against the campaign number for the belt requiring replacement (left or right) and as a result only the campaign for the safety belt being replaced will be "closed". Should the opposite side (unreplaced) safety belt lock-up or jam in the future, it can then be replaced and a claim submitted under the remaining "open" campaign number.

VISS (Vehicle Information Service System) will identify both campaign numbers as outstanding on an involved vehicle until service action is performed on that vehicle. Once a campaign claim is submitted, however, the campaign number associated with that claim will be removed from VISS for the repaired vehicle. For example, if only the left (driver’s) side safety belt is replaced on a vehicle, and a claim is submitted for that side, VISS will show only 91C26 (right side) as outstanding for that vehicle. See the "CLAIM INFORMATION" section (page 10) of this bulletin for special claim submission instructions.


Involved are certain 1984-91 Chevrolet Corvettes built within the following VIN breakpoints:

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.


Sold unit vehicle owners will be notified of this campaign on their vehicles by Chevrolet Motor Division (see copy of owner letter included with this bulletin). Dealers are to provide a copy of the attached owner notification letter to future owners of affected new or used inventory vehicles. Mailing of owner letters will be scheduled as parts become available.


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.

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 ensure the campaign notification letter has been provided to the owner 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 are to be made to provide the owner with a copy of the notification letter.


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 f rom GMSPO as a VERIFIED VIP. For VIP Overnight Delivery, please refer to GMSPO VIP Overnight Delivery Program Bulletin No. IB90-110 for ordering procedures. The part will be shipped premium transportation at the dealers expense. Reimbursement of freight charges may be applied to the campaign claim. All other order types will be placed on back order.

NOTICE: Perform this procedure for any involved vehicle in which a customer has complained of the retractor side safety belt locking-up. Only safety belts which experience the locked-up or jammed condition are to be replaced.

If only one safety belt in the vehicle is experiencing the condition, replace that safety belt and inform the owner that the opposite safety belt will be replaced at no charge should it develop the condition in the future. Be certain to advise the customer that the occurrence of this condition can be avoided by always buckling the safety belt before moving the vehicle.

For customers who have not experienced this condition on either belt but who question whether repairs should now be made, advise the owner to retain the notification letter and to return to the dealer should the condition occur. Again, be certain to advise the customer that this condition can be avoided by always buckling the safety belt before moving the vehicle.

Safety Belt Assembly Replacement:

1. Remove and replace affected retractor side safety belt(s) following procedure in appropriate Chevrolet Corvette Service Manual (It is not necessary to replace the buckle side safety belt assembly although the part is provided when a retractor side safety belt is ordered).

2. Verify proper operation of safety belt (latch and buckle) assembly.

3. Install Campaign Identification Label.


Each vehicle corrected in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label." Each label provides a space to include the five (5) digit dealer code of the dealer performing the campaign service. This information may be inserted with a typewriter or a ball point pen. PLACE A CAMPAIGN STICKER(S) ON THE VEHICLE ACCORDING TO WHICH SAFETY BELTS HAVE BEEN REPLACED (i.e. IF ONLY THE LEFT SAFETY BELT WAS REPLACE ONLY INSTALL A STICKER FOR 91C25).

Each "Campaign Identification Label" is to be located on the radiator core support in an area which will be visible when the vehicle is brought in for periodic servicing by the owner. Additional "Campaign Identification Labels" can be obtained from DAC.

Apply "Campaign Identification Label" only on a clean, dry surface.

General Motors has determined that a defect which relates to motor vehicle safety exits in certain 1984-91 Chevrolet Corvettes. Under specific conditions of vehicle operation and occupant usage, it is possible for the safety belt in your vehicle to lock-up or jam in the retractor. If this occurs, you will be unable to use the safety belt because it will be impossible to pull the belt out of the retractor. In the event of a vehicle crash, unbelted occupants are more at risk of injury than those using safety belts.


If either of the safety belts in your Corvette has this problem, you will be unable to pull the belt out of the retractor and buckle up no matter how hard you pull. If you currently have a safety belt that is locked-up, please call your Chevrolet dealer right away and schedule a time to have the safety belt replaced. Be certain to tell the dealer the model year and interior color of your Corvette so they can have the proper safety belts for your car when you come in.

In addition, if you ever have this problem in the future - no matter when - contact your Chevrolet dealer for safety belt replacement. Please keep this letter in your Corvette, so that any future owners will also know of this situation.

Most Corvettes will never experience this problem because it can only occur under specific conditions of safety belt use. You can avoid having this occur by simply fastening your safety belt before you start driving your Corvette. This is clearly the best safety belt use routine, and is what your owner’s manual recommends.

The retractor lock-up problem can occur only if you attempt to fasten the safety belt while either accelerating, braking, or bouncing over a rough road so that the retractor attempts to lock-up as it would in a vehicle crash. If this condition occurs and you have just started to pull the belt out of the retractor (first six inches of belt travel) you will feel resistance as the retractor attempts to lock-up. Continuing to pull on the belt in spite of feeling this resistance may break the retractor and you would not be able to use the safety belt.

If you have previously paid to have either of your safety belts replaced because of this condition, we want to reimburse you. Please bring documentation to your dealer which reasonably confirms the amount of unreimbursed repair expense, the date of the repair, and the person or entity performing the repair so you may submit a claim for reimbursement.


If either safety belt in your Corvette is currently locked-up - or ever locks-up in the future - we will replace the safety belts at no charge. Chevrolet is utilizing a special parts distribution program designed to help put the right replacement safety belt in your dealers hands quickly and without delay.

Instructions for making this correction have been sent to your dealer and parts are available. The labor time necessary to perform this service correction is approximately one-half (1/2) hour. Please ask your dealer how much additional time will be needed to schedule and process your vehicle.

Your Chevrolet dealer 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 dealer 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 Chevrolet Customer Assistance Center by calling 1-800-222-1020.

After contacting your dealer and the 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 dealer 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.
