Product Emission - Loss of Hybrid Function - Voltage Imbalance

The service procedure has been revised to include shipping information for Canadian dealers. Please discard all copies of bulletin 07318, issued February 2008.

This recall covers the condition for a period of 8 years or 100,000 miles (160,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.

Due to part availability, this recall is being administered in phases. This is the third and final phase.

General Motors has decided to conduct a Voluntary Emission Recall involving all 2007 model year Saturn AURA Green Line Hybrid and VUE Green Line Hybrid vehicles and certain 2008 Saturn AURA Green Line Hybrid vehicles. A battery case condition on these vehicles may cause a voltage imbalance in the hybrid battery. If the imbalance exceeds 0.6 volts, the check engine light will illuminate and hybrid function will be disabled. If this occurs, the charge/assist gage would show no movement, the fuel economy light (ECO) would not illuminate, and the vehicle will be powered by the gasoline engine only.

Retailers are to replace the 3 hybrid cassettes that make up the battery assembly. This recall covers the condition for a period of 8 years or 100,000 miles (160,000 km), whichever occurs first, from the date the vehicle was originally placed in service.

Involved are all 2007 model year Saturn AURA Green Line Hybrid and VUE Green Line Hybrid vehicles and certain 2008 Saturn AURA Green Line Hybrid vehicles built within these VIN breakpoints

Returning the Battery (U.S. Retailers)

Return hybrid battery parts via dedicated delivery to SSPO following the existing Core Return Process. Place the batteries in cages along with the other return freight. While there is no core value for these batteries, returning them via the Core Return Process will ensure that the batteries will be recycled or disposed of properly.

Package the part to be returned in the same container that was used to deliver the replacement part. This container has specific labeling for a Class 8 hazardous materials that are exempt from a hazardous material classification for the purposes of transportation.

Returning the Battery (Canadian Retailers)

Each hybrid battery cassette must be placed in two (double) polyethylene 6 mil bags that were provided with the new replacement batteries. This double bagging procedure must be performed as soon as the hybrid batteries are removed from the vehicle. If the bags were not included with the batteries, contact your Saturn Saab Service Parts Assistance Centre (SPAC) before commencing with the removal of the hybrid battery. After bagging the individual battery cassettes separately, place the three bagged cassettes in the original cardboard shipping container (three cassettes per container), seal with packing tape and mark the repair date, repair order number, and your Retailer Code on the top of each container with a permanent marker.

Store/stack the shipping containers on a wood pallet located in a cool dry area inside the retailer shop facility (do not store outside). Arrange the shipping containers on the pallet with six (6) containers in each layer and maximum five (5) layers high. Ensure the pallet is secure from physical damage.

Note: Do not store any other batteries on the same skid as the Hybrid Batteries.

Once the skid is full (30 containers maximum) or every 6 months, whichever occurs first, contact Newalta Industrial Services at 1-888-772-2543 to arrange for pick-up. Please reference GM Recall 07318 during your conversation with the Newalta representative and provide him/her with a contact name and phone number for the retailer, and the number of containers to be collected. Newalta will prepare the necessary documentation and arrange to collect the batteries from the retailer and transport same to the arranged recycling facility at no cost to the retailer.

Following this procedure will ensure that the batteries are transported and recycled properly in accordance with Canadian laws.

Place a Recall Identification Label on each vehicle corrected in accordance with the instructions outlined in this Product Recall Bulletin. Each label provides a space to include the recall number and the five-digit retailer code of the retailer performing the recall service. This information may be inserted with a typewriter or a ballpoint pen.

Put the Recall Identification Label on a clean and dry surface of the radiator core support in an area that will be visible to people servicing the vehicle.

When installing the Recall Identification Label, be sure to pull the tab to allow adhesion of the clear protective covering. Additional Recall Identification Labels for US retailers can be obtained from Retailer Support Materials by ordering on the web from DWD Store, www.gmretailerworld.com, and then click on the DWD Store link. Request Item Number S-1015 when ordering.

Reason For This Recall:

The recall includes all 2007 model year Saturn AURA Green Line Hybrid and VUE Green Line Hybrid vehicles and certain 2008 model year Saturn AURA Green Line Hybrid vehicles. There may be a voltage imbalance within the hybrid battery. If the imbalance exceeds 0.6 volts, the check engine light will illuminate and hybrid function will be disabled. If this occurs, the charge/assist gage would show no movement, the fuel economy light (ECO) would not illuminate, and the vehicle would be powered by the gasoline engine only.

What Will Be Done:

Your Saturn retailer will replace the three hybrid cassettes within the battery assembly. This one-time service will be performed for you at no charge within a period of 8 years or 100,000 miles, whichever occurs first, from the date your vehicle was originally placed in service.

How Long Will The Repair Take?

Because of service scheduling requirements, it is likely that your retailer will need your vehicle longer than the actual service correction time of approximately 2 to 3 hours.

Contacting Your Retailer:

Please contact your Saturn retailer to arrange a service date as well as get an estimate on how much time will be needed to schedule, process and repair your vehicle.

If you have any questions or need any assistance, just contact your retailer or the Saturn Customer Assistance Center at 1-800-972-8876, (1-800-833-6000, TTY).
