My 2017 did it at 6k. I was driving down the freeway and when I got off flames poured out from under the hood. The gasket leak caused the coolant reservoir to overflow with oil, the coolant overflow hole squirts the excess out below the engine and above the exhaust where it ignited. No engine mods and I did the break in period properly so I have no idea what could have caused it.
