I have a 2007 Compass that has developed an issue with, I think, the transmission.
My father in law normally drives the car and told me today it wouldn't go over about 30mph and struggled to get there. I drove the car and noticed it. I also noticed the check engine light was on. On a lark, I disconnected the battery and took the car for a drive. It drove fine.
We drove it about 8 miles to the store. When we came out and left it was doing it again. I pulled over, disconnected the battery and all was fine again.
I haven't driven it again tonight, but I suspect it will act up again.
Is this a transmission issue or possibly a computer issue?
I also noticed the headlights acting strange. They would not turn off unless I turned the switch on and then back off. That got me to thinking maybe it was the computer.
Any insights would be greatly appreciated!
