When it gets cold (10 - 20 deg.F) starting car in the morning noticed that voltage gauge jumps up to 16V (actually observed 16.7V !). As car warms up, it drops down to 13.7 V at normal driving revs and then behaves. I don't think that car's electronics appreciates seeing 16V+ even for 3-5 minutes. Did anybody experienced similar voltage regulator behavoir, or should I bring dealer's attention to such phenomenon?
