I got my 2013 Express stuck over the weekend in my driveway.
I was going forward and back a few times before I had to pull it out. The stabilitrack and reduced power modes kicked in. I was spinning the wheels some.
The next day it would not start. So I check to see if there were any codes. It had a P1682. I cleared it and it started up no problem. Drove it around some all seemed fine. It started yesterday no problems drove fine.
Today it would not start just cranking over like before. Checked for codes again and the P1682 was back. Cleared it and it started up no problem drove it down the street and back./ Shut it off and it started back up.

Anybody have any ideas of what may be causing this?
I am a little reluctant to drive it in case it wont start and clearing the code wont work.

Thanks.

 

Not familiar with that code... Here is a link to the diagnostic instructions.
p0685

Good luck I guess?

 

Thanks!
I will hopefully get to it this weekend.
