Had my Cobalt for a few months now, and I noticed that when I'm going at a steady speed on the streets (between 35-40 mph usually) the engine revs as if I am giving it gas and letting it off rapidly and the tachometer jumps between 2000 and 2500 RPMs. It's hard to explain but here is a video of another vehicle (a Malibu of the same year) doing the same thing, but at a different speed.

I'm driving an automatic, if that changes anything.

Thanks!

I still have the powertrain warranty on the vehicle. Would this be covered service?

And no, its not throwing any codes of any sort. Other than this issue, the car is running perfectly.

Yes, this would be covered under extended powertrain warranty.
