Probably due to excessive backpressure in the exhaust. Remove the catalytic converter and install a bypass pipe temporarily. Test drive it. The problem should be fixed. Then replace the catalytic converter. You can do it yourself in about an hour with a jack, stand, and 2 wrenches.

The vehicle is almost new and should be under warranty. I would let the dealer sweat over it.

Have it scanned for both hard and soft codes and let us know what is fund. You have to tell them you want soft codes scanned, because they don't set the Check Engine Light.
