2021 equinox smoking

[hmm457]

My 2021 premium awd equinox started smoking out of the muffler yesterday at 29,000 and had a terrible smell. Oil looks ok and the coolant is full. Does anyone have any ideas what might be the cause or has had the same issue?

 

[Hey Vern!]

No codes or CEL? Did it smell like rotten eggs, raw fuel, or something else?

How many miles on it? Maintenance history?

What color is the smoke? White, Blue or Black?

Dense white smoke indicates a cooling system issue leaking internally, blue smoke tends to be oil burning, and black smoke is unburned or partially burned fuel in the exhaust
