Strange Engine Issue

[djaqualight]

This is the 3rd time that i've cold started the H3 (not literally that cold outside) and the engine makes a loud grunt, choking sound (almost like a misfire) when it first turns over. There is also a strong smell of engine exhaust in the cabin right after it turns over. Once started everything seems fine, no performance issues or warning lights. It only seems to happen when it hasn't been started several hours or overnight.

should this be something that the dealer should look into?

Thanks
