I have a 2012 Cadillac CTS. Drove fine yestersday. No problems. Today it wont start. All lights, radio and locks work. Turn the key and no reaction.
The battery should be checked, may be low on charge or no good. Check and clean the battery cables.
Agree w/ Rowefast. With anything that happens all the sudden and combined such as idiot lights, hard to start and rough idling , it's likely the battery.
