I own a 2016 Toyota Scion IA. Has anyone replaced battery yet? I have 50k miles on it. My check engine light came on. Just a solid orange. I drove it over to Autozone to have diagnostics ran. Guy bsc said no big deal just drive on it to reset it. Real short with me so I asked him to test the battery he couldnt get a reading not sure why. Should I just go ahead and replace the battery and see it the light goes off?
