It is a good probability, The leveling system has had a popping problem on its leveling system. They have tried to help the problem by adding a quart of a different oil. There are several different ones that they recommend. This has been out for a while so I would think the units in at least the last 6 months or more would have it. I haven't put any in mine. It is a '12 unit. It used to pop more , but I don't know if its from use or what but it pops a lot less now.
