Check engine light

[Jkw2215]

Recently my 08 kia sportage became louder as I accelerate and now check engine light came on the codes it read were: evaporative emission system leak detected, gross leak/no flow, possible vacuum leak. I do not hear hissing

Did you check the gas cap? (That's the most common cause of evap leaks.)

Since you said the car is getting louder, most likely there's some sort of major leak in either the exhaust or intake. My guess would be intake based on the codes you're getting.

Or it is just coincidental the exhaust has rusted apart...in conjunction with a bad gas cap
