White smoke coming out rear of vehicle 2017 Honda pilot elite

What is your question?

The car is missing when I push the gas and smoke comes out the rear. Had the fuel injector replaced and it's sill doing the same thing. Transmission light pops on hill assist pops on engine light and etc. I only have 38000 on vehicle and haven't had it a year yet

What makes this problem better or worse?

When I don't give it a lot of gas runs ok
