If it happens again, if it was mine, the answer would be yes.
I hope you pull over to the side of the road before trying to take video while driving.Next time take a camera or phone with you and start recording when it happens. This way you have concrete proof of what is going on and they can then replace the unit. If it's something intermittent like this then they need to reproduce the issue before they can do work on it. I'm pretty sure the list prices on those components are very expensive so they wouldn't touch it unless there's proof like a video showing exactly what's happening.
