I drive a 2017 KIA SORENTO V6 with automatic transmission. I bought the car used with 18k miles on it. Recently I drove with windows down and noticed a chirp/sputter like sound upon light/moderate acceleration. Sounds like it was within the engine compartment. No codes or lights on the cluster. I don't beat on this car, I drive it casually and perform my own oil changes. With your experience could this be a loose component somewhere or will this be something expensive? I know it's not a lot of info to work off of but it's all I have. When stationary I revved a little and didn't not hear the sounds so it's only under driving conditions. I put Royal Purple's injector cleaner in yesterday when I topped off so I'll let that do it's thing. Thanks!
