general problems of the 2008 Saturn Vue Hybrid

First off I have had this issue from the beginning. Basically my car's electrical system pulls back and then all the lights start to go off. Elec stability control, air bags, the steering sort of locks up and I have stalled on occasion. I have had my car in the shop numerous times this issue and it never seems to get fixed. It sounds like the same issue gm is having with their current recall but my car is not on the list. I have only one key on my key chain and that does not seem to make any difference. It is a very uncomfortable feeling not knowing if my car will work tomorrow. Delillo Chevrolet in hunting beach, CA has been very helpful in trying to detect the problem and they have been very gracious but I need the issue resolved once and for all. My intention is to hand down this car to my 16 year old but not if the current issue persists.
