2017 Cadillac ATS 4dr Sedan

turbocharged 272hp 2.0L I4 8-speed shiftable automatic AWD

25000 mi Engine light came on last week, Thursday Nov. 5 and made an appointment to check. Was scanned through OnStar, contacted Dealer Service and was told to bring it in. Engine light went off by Friday. But took it in anyway. They scanned and reviewed if there was a problem. Since the pandemic and no longer working I have not been driving the car as often. Dealer did as if I have been driving it as before and told them no. They concluded after looking at the car and charged the battery that it maybe the electrical system since my car is not driven as often as before. We will be monitoring.
