Odd behavior in our 2007 Nissan Frontier. Anyone know what's going on?

A couple weeks ago, our truck started doing this weird thing. It beeps (sometimes), and the odometer goes to zeros (not really zeros, they are shorter--more like half of an eight) for a second, then it goes back to normal. It doesn't seem to happen in any kind of pattern--it seems totally random.

We called the Nissan place and they had no idea what we were talking about. We thought there wasn't much point in taking it in, as the behavior has been completely unpredictable. Tonight we were finally able to catch it on our camera.

(it happens about 40 seconds in)

We plan to take the camera up to the dealership so they can see it happen, but I thought I'd see if anyone on here had experienced anything like this.

 

Hmm... never heard of anything like that happening.... let us know what the dealer comes up with.

 

have the dealer check the conections at the bcm - body control module, both in & out. loose connections could be causing this. also check the conections where the speedo cluster plugs into the main harness under the dash
