Last weekend in da up would start up the old girl in the morning and it would take about 2-3 minutes for dash and low beams to power up. High beams would take even longer 7-10 min? My dealer blamed it on the cold weather (still have warranty till 1-23). Is this normal? Was about -10 -15. The problem seems to be consistent with the temp., works fine when it's 10 or warmer. THANKS.
