girlfriends preowned 2018 optima 2.4 is running great BUT the heater seems slow to heat in its first winter in Pa. her 2008 jetta was even worse but also ran great. input appreciated! happy + healthy holidays to all!
Not really heard of slow heating problems with the Optima, in fact on our '11 it
heats up pretty quickly. Need to make certain the coolant gets up to proper temp
and heat hot. Only way I know is to watch/check the coolant temp through the
DBII access or eyeball the gauge to see if up to normal.
