Transmission hesitation occasionally

[Slip_Angle]

Followup... the dealer said he needs new coils and spark plugs. They said it's not safe to drive.

Thanks for all your help.

Probably just one bad coil or plug but they don't want to troubleshoot to figure out which one.. also safer for the dealership to just replace them all.

Thanks!

Weirly enough, we had a long talk late last night. I'm now thinking it might be an engine misfire because he had several episodes of a feeling of hesitation when driving at a steady speed. He was using sport mode 'just because' at times and it's never done this in comfort mode. I suggested he keep it comfort mode (duh) but I can't see how that would effect something like an engine misfire or something similar. I'm no car expert but that makes me even more interested in what an OBD might show.

He's a 15 hr drive from the next Kia dealer (Whitehorse YT).

This sounds quite similar to what I am experiencing in my 2018 V6 Stinger, except the dealership says they found nothing wrong and couldn't replicate this hesitating/skipping sensation.
