Built at Moraine Assembly Plant

ON SEPTEMBER 27, 2002 ALL VEHICLES INVOLVED IN THIS RECALL WERE PLACED ON STOP DELIVERY. AFTER THE SERVICE INSPECTION CONTAINED IN THIS BULLETIN IS PERFORMED AND IT IS DETERMINED THAT THERE ARE NO MISSING WELDS, VEHICLES MAY BE DELIVERED TO CUSTOMERS.

Condition

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2002 and 2003 Chevrolet TrailBlazers and GMC Envoys. Some of these vehicles are missing welds on the rear floor pan. In a crash, missing welds could degrade performance of the third row seat and safety belt anchorage and occupants could receive greater injuries.

Correction

Dealers are to inspect for missing welds. If missing welds are found, dealers are to offer customers an exchange for an equivalent vehicle or a refund of the purchase price. These options are the only options being made available to customers because the repair procedure is extensive and dealers are not equipped with the proper tools to perform this repair. If the vehicle is returned to the dealership's possession on or before October 31, 2002, the mileage depreciation allowance will be waived.

Dealer Recall Responsibility

Important

See additional dealer responsibilities in the section titled “Replacement/Repurchase of Vehicle” located in the Service Procedure.

The US National Traffic and Motor Vehicle Safety Act provides that each vehicle which is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty 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 customer 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 remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.

All unsold new vehicles in dealers' possession and subject to this recall MUST be held and inspected/repaired per the service procedure of this recall bulletin BEFORE customers take possession of these vehicles.

Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such customers a copy of the customer letter accompanying this bulletin. Recall follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.
