The problem with modern car is there electrical in nature which mean every thing depend on it, and anything that has a plug can get corroded to a point it looses contact intermittently.
That being said, your care is 9 years old, and you replaced the terminal, start there
Check your ground's,battery/body, and In the fuse box pull all fuses, put them back in, as well as the solenoids (electrical switches that turn thing off and on, like dash panel lights.)
this simple act can save you a shop call.
Let us know what you find.
