Un-plug OnStar or pay alot for diagnostics at a dealer
I had the same problem. I bought a AGP battery and a trickle charger. Problem fixed!!! Took the car in for service several mo's later, (obviously no trickle charger plugged in at dealership) and the battery was drained a day later. After a couple of hundred bucks in fees for diagnostic tests, was told there was problem in one of three computer circuits to "On-Star" and it would take several more hours to find and fix. I was also told in was not an uncommon problem with XLR's and often was caused by a wire rubbing against the chassis "somewhere".
To me, OnStar wasn't worth the money, so I had it disconnected. Since then, ZERO problems.
Having a dependable battery charge is worth alot more to me, than OnStar.
