Recall - PCM Failure Caused by Electronic Suspension: Overview

Product Safety - Electronically Controlled Air Suspension/Powertrain Control Module # 04048A - (Sep 14, 2004)

Models:
2002 GMC Envoy
2002 Oldsmobile Bravada

Equipped with Electronically Controlled Air Suspension (RPO G67)

THIS BULLETIN IS BEING REVISED TO CLARIFY THE DISCONNECTION OF THE ELECTRICAL CONNECTOR FROM THE ECAS COMPRESSOR (STEP 2 IN THE SERVICE PROCEDURE).

Condition

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2002 model year GMC Envoy and Oldsmobile Bravada vehicles equipped with electronically controlled air suspension (ECAS) (RPO G67). Some of these vehicles have a condition in which the ECAS may produce a brief electrical spike while the vehicle is operating. This electrical spike can disrupt the powertrain control module (PCM) causing the vehicle to stall. If the spike damages the PCM, the vehicle may not restart. If this happens while the vehicle is moving, a crash could occur without prior warning.

Correction

Dealers are to install a wiring harness.

Vehicles Involved





Involved are certain 2002 model year GMC Envoy and Oldsmobile Bravada vehicles equipped with ECAS (RPO G67) and built within the VIN breakpoints shown.

Important
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) before beginning recall repairs. [Not all vehicles within the above breakpoints may be involved.]

For dealers with involved vehicles, a Campaign Initiation Detail Report containing the complete Vehicle Identification Number, customer name and address data has been prepared and will be loaded to the GM DealerWorld, Recall Information website. Dealers that have no involved vehicles currently assigned will not have a report available in GM DealerWorld.

The Campaign Initiation Detail Report may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.





Parts Information

Parts Pre-Ship Information

Important
An initial supply of wiring harnesses required to complete this recall will be pre-shipped to involved dealers of record. This pre-shipment is scheduled to begin the week of August 9, 2004 and will be approximately 15% of each dealer's involved vehicles. Preshipped parts will be charged to dealer's open parts account.

Additional parts, if required, are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO=Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO=Customer Special Order.

Customer Reimbursement

All customer requests for reimbursement for previous repairs for the recall condition will be handled by the Customer Assistance Center, not by dealers.








A General Motors Product Recall Customer Reimbursement Procedure Form is shown.

Important
Refer to the GM Service Policies and Procedures Manual, section 6.1.12 for specific procedures regarding customer reimbursement and the form.

Courtesy Transportation

The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product recall is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.





Claim Information

Customer Notification

General Motors will notify customers of this recall on their vehicle (see copy of customer letter shown in this bulletin).

Dealer Recall Responsibility

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. A copy of the customer letter is shown in this bulletin for your use in contacting customers. 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.
