And I just called the Chevy dealership and the service guy tells me they can’t see my problem bcus they can’t go over 70mph when diagnosing it. Car still under warranty until 2024. What should I do?

Probably needs spark plugs and or coils there should be a code stored for what cylinder is having a issue even if they can’t actually make it misfire
Thx, will that be covered under a powertrain warranty? Or is that considered coding?
