Same thing happened with my 2014 Chrysler T&C with 121,000 miles on it. After extended traffic backup on warm day battery light came on. Had the battery and charging system checked and Both checked good. No corrosion on terminals. Everything tight and belt good. Starts strong. Drove another 125 miles and light went out by itself. Got home and drove around town next few days - no problem. Idled in warm weather a few days later while waiting for wife doing shopping and light came back on. Still starts strong. Has to be a sensor but, no trouble code shows up. Any ideas?
