Depending on how long you've had it, see if the retailer will exchange it. I've had my replacement from Drone Nerds a few weeks now and the new one is operating perfectly.
No. Drone Nerds exchanged it for a new one. I have no info on the underlying problem. There's clearly an issue as several folks have had it on their brand new MA2s.
I just got my MA2 and am experiencing the exact same thing. Not sure if it's the heat or the wind. The video gets that weird wavy look to it when it starts.
Did you process your exchange through DJI or a third party authorized seller?
