Default 2010 impreza 2.5i 4eat - ABS and TC lights

Turned my car on this morning and my ABS and TC lights turned right on, and the car did not want to shift out of park. Turned the car off/on again and was able to get my car into reverse.

The lights went off but came back on right down the street. Turned the car off at a light and couldn't get it back in to drive for a few seconds. Stopped for coffee and the lights didn't come back on shifted out of park just fine - made it to work without the lights coming back on...

Car accelerates and brakes fine... I had the lights turn on once last winter and turning the car off then on again fixed the issue. We've had some pretty dramatic temperature shifts in Boston. It was in the high 20's 2 mornings ago and it's almost 70 this morning. I did read that the car may do this if the brake fluid is low, which i'll need to check at lunch, and may have something to do with the temperature shifts.

Any ideas???

Do your brake lights come on? Have someone step on the brake pedal with varying rates of speed and force while you watch the brake lights, the brake light switch may be starting to intermitently fail. Not super common i think but they do fail.

Im pretty sure the brake lights come on... but I'll check.

I also checked my break fluid and it's basically topped off. Turned the car on at lunch and no ABS or TC lights, and shifted out of park just fine. Hopefully it was just a freak thing.

When I was shopping for my impreza a similar thing happened with an 09 I test drove but it was a manual. The hill assist, Trac control and abs lights all came on any time I got the car over 40. Stealership owner said it was a sensor on one of the rear hubs.

I went 3 days without it happening, then it happened again this morning. I'm almost at 58k so It's time for a trip to the dealership anyways.
