On December 23 we had a temperature 0f -11 degrees on my way to work and about 15 minutes into my trip I noticed that my speedometer read about 20MPH faster than I was was actually going. Has anyone noticed this? After I got home and put it in my heated garage it went back to normal..

Nope. However, this morning, when the temps ranged from 1 to 5 degrees Fahrenheit, my backup warning system malfunctioned such that it dinged away with open space behind me when backing. I figured it was the cold and will see how it behaves in a couple days.

Perhaps your wheels were spinning that fast on the ice.
I'm curious - how fast were you going in your garage to note it read the same speed?

A few weeks ago my analog speed was reading about 10 too fast, digital was still correct. A quick google search said that they can get out of wack but it should self correct after a couple of ignition cycles. It corrected itself and hasnā€™t been an issue since.

Is this the analog needle gauge you are talking about?

Yes the needle gauge was reading fast but all is good now.

Did you check and make sure you didnā€™t accidentally hit the left or right button on the digital speedometer setting and make it go to kilometers?

You have to be stopped and in the "settings" menu to do that. Not easy, IMO.
While moving and viewing the speedometer hitting the left or right simply changes the view.
Possible to change, not not really easy.
He was talking about the "analog" gauge reading wrong - no setting on that one I can recall. It's set at mph.
