Speedometer Issue

My speedometer is acting weird. Sometimes the analog sticks and shows that I'm driving faster than the digital display. I shut it off, restart it and it's fine. I had the dealer check it a couple of months ago and I was told nothing was wrong. Anyone else experience this? If so what was the issue?

 

You’re still under warranty, I’d let another dealer look at it

 

I think you should try to get a video of it when happens. Probably just a defective unit. Or take it to a different dealer.
