Still having issues. Twice this weekend the car would not start, both times I had started it and moved in from the garage out to the driveway to clean it. My sub has been disconnected for a week. I had the battery tested at Advance Auto Parts - 12.5 volts and over 1000 cca. I measure voltage with the car running and got 13.5 at the battery and 13.9 under the hood on the jump points. I guess I will have to make an appointment with the dealer.
