We've noticed our 2019 Ascent with 36k miles revs up to 2500-3000 rpms at any slight incline and we are not trying to accelerate. Anyone else having this problem? Dealership can't find anything wrong with it, no warning lights on. had had all the updates done. Sounds like the transmission is slipping. Wondering if the 2020-2021 does the same thing? Was thinking about trading it but I don't want to have the same problem in a newer model.
