So my 2010 occasionally has the same issue, when it first started I would lose hill decent and active traction. Over time it got progressively worse where my gauges would go dead and then total loss of power at times. I found that when I removed the gauge cluster and reinstalled it things would start working, at first it was thought that it might be a gauge cluster issue. What I found is the wiring connection at the top of the cluster on the right side has an issue and after removing the bezel I was able to reach in and move the wires and everything started working. It took quite a bit of jocking the wires on occasion to get things working a few times. I would check this first just to see if yours is the same.
I had done quite a bit of research and did not see others reporting this. I have been trying to see if I can get a part number for this wiring harness and replace it but thus far have been unable to find the part number. I am considering going to a junk yard and trying to see if I can grab this or at least the gauge connector and about a foot of the wiring harness to solder in if all else fails.
