I have had a 2010 SXT for about 3 years now and all of a sudden my tire pressure gauge came on the other day. Checked all the tires and all had correct pressure. Few hours later, battery warning light came on. Took it to have alternator tested, it's also fine. The tire pressure light seems to stay on constantly now. But the battery light seems to only come on after idling for 5 min or so. Like while sitting in a drive through. Turn it off, let it sit for a while, turn it on and no battery light until it's sits and idles for a bit again. Anyone have any suggestions? Greatly appreciate the help.
