driving to work on very busy highway. The engine light and Service Battery charging system came on, then went to battery saver almost instantly. Radio cut off, heat cutt off and the Car cut off in the middle of the highway before I could safely get over. this caused me to fear for my life as the cars behind me barely had time to stop. a hair probably could not have fit between us. I did eventually safely get off the highway, had the car towed to a service center. There was 14 different codes.(low voltage, engine running lean, low voltage and more. battery was checked and was 95 %, Alternator fine. was told it was the ECM. After looking on google some sites say there is a recall for 2013 cts some say there is not. there are multiple complaints on this issue and it is not safe. I called Cadillac gave my vin number and was told there was not a recall. Cadillac/GMC really need to issue a recall before something tragic happens, as it almost was me. Thank God that it wasn’t.
