2009 HHR SS--About 1min 40 sec after first started 3 chimes and the battery light illuminates. Stays on about 4min 40 seconds and goes out. Digital volt meter indicates 13.8-13.9 volts. Cruising along about 3 minutes later battery light illuminates WITHOUT chime stays on about 1 minute and goes out, steady state charge indicates 13.5-13.6 volts. Does this on first start every morning, regardless of radio or A/C on or off. Dealer has replaced fuse panel, alternator and ignition switch to no avail, GM tech involved. Any ideas? There are no aftermarket Navigators, radar detectors, or cell phone chargers in the vehicle, and all lights are out, interior and exterior when vehicle is parked. HELP!
