I bought a brand new 2020 Ascent Premium in late 2019 and been dealing with a jerky transmission ever since. I brought it to my dealer and they test drove it and said it is normal. I never had a CVT tranny before and don't know if this is normal. The hesitation occurs usually at low speeds and then going up a grade the engine revs up but then there is no corresponding shifting or increase in speed. It always seems like the transmission does not know what to do. I know the 2019 Ascents had transmission issues and I wonder if I got a transmission from the 2019 model run. I sent a email to Subaru of America and got the standard corporate response of thank you and inform your dealer. It seems that the engineers designed this high tech CVT system and overlooked the basic idea of a smooth driving vehicle. Every time I drive this Ascent I wonder if I should just deal with it and keep it or get rid of it.
