Here is a something I found about the battery issue after my last post.

"Here are the important paragraphs from the recall letter:

The recall includes all 2007 AURA Green Line and VUE Green Line as well as 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 gauge 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 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.

By the way - this recall pertains to ALL 2007 VUE Greenline models from VIN (last 8 digits) 7S800023 thru 7S880949 UNLESS your 36V battery cassettes had already been replaced sometime in the last few months with the latest part numbers (PN# 25953382 or 25964892 for the VUE GL)

Most owners have yet to receive the letters as they will be coming out in stages. "
