The other day my car was buried in snow. After I cleaned it off, I got in and started. I noticed the RPMs started to fluctuate. Right as I started to put it in reverse, the car shut off. I turned it on again and I got a half engine light and the 4x4! light. The car was definitely driving oddly. Seems weird but the front end seemed to be lighter...I'm not sure if this is because the AWD system turned off. I went to my destination and turned off the car. I got back in after an hour to go home and no lights, and the car drove fine.

This was about a week ago, and since then it's been okay. It also hasn't snowed at all though. Anyone else run into this issue?

Never had that, but have had other cars toss weird codes when it was stupid cold out. Once I cycled the key it was fine.

Exhaust stuffed with snow? Easy to forget that when you are digging out.

The battery may have been low because of the cold, maybe through a random code...Weird if it was the AWD though.

The car does act a little funny sometimes, but if you car warms up and still is acting funny then there is something wrong. I know when my car was sitting outside for 10 hours in subzero some of the electronics didn't act right. Like the heated steering wheel. I would think unless you have a diesel or snow got into some place it shouldn't besides being stiff it should work normal.

"besides being stiff it should work normal"

that's what she said
