I just had this happen on my 2014 CT F sport with 108k miles. It would run if I jumped it but ended up having to take the battery in to Autozone and they confirmed it was bad. I purchased the replacement at BatteriesPlus because they are the only place with a 4yr full replacement warranty and they usually have a 10% buy online and pickup in store coupon. I got the same deal the year before for my other 2013 CT F Sport.

If you are replacing it, make sure you DO NOT close the hatch back door without a battery in it, or you will have to crawl in through the back and manually release the door.
