I have been having trouble with my 2014 Crosstour for two weeks
Initially I had starter problems and had the started replaced
Recently while driving the car seemed to hesitate and then return to normal. I thought that it could be a transmission problem but
the lights dimmed and the communication screen went dark for a about a minute
The next day the car started fine, I turned it off to go to the store and when i returned the car would not start
AAA was able to jump start the battery after playing with the battery cables
I replaced the battery but the issue came back
The car will shut down and I lose the communication screen while stopped at a light
My mechanic has been unable to duplicate

Help
