I know this post is long, just trying to give as much relevant info as possible.

So I'm having 3 mechanical issues with my 2019 ascent. 2 im able to recreate the issue so I'll be taking it in soon for those. One is a grinding type noise from the front passenger wheel. Sounds exactly like an issue I had with my cherokee that turned out to be a bad bearing or something like that. 2nd is in stop and go or slow traffic under light acceleration. There feels like a slight shudder around 15-20mph. Im assuming its the fake shifting acting up. But the one I cant pin down what it is or how to recreate it to show subaru, is from time to time the car will buck back and forth. Like im rapidly pumping the breaks, but the rpm bounces quickly +/- 300 rpm while this bucking happens for the 1-2 seconds it going on. The only thing I can say about this issue is it seems to do it more often on really cold mornings shortly after I start my drive to work. But it will still do this later in a day aswell just not as often. Anyone have a clue as to what this bucking issue is or how to resolve it? Im planning a long drive camping trip in a few months towing 3500-4000lbs. Im sure if any of these 3 issues act up while towing it will end up being a bad day for me. Ive had the 2 recalls done already. The recalls did help with the shudder and bucking a little bit, however it didnt take the problems away. Any help is appriciated.

Sounds to me like the torque converter lockup...it typically does this between 15-20 MPH. But Ive been wrong before!

I have my 2020 in at th dealership right now for the same problem. I believe what you are feeling is the torque converter coming in way too early and causing the shutter or as we called it when I was the service director with GM, the infamous torque converter "CHUGGLE". As for the grinding the brakes have been updated three times to address the grinding noise. There have been lots of replies to that along with part numbers on this forum in the brake section. I am think your answers will be found there.🙂

My 2020 limited with only 10,000km on it started doing a similar stutter on light acceleration, sometimes low speed but usually up a light grade at around 50-60kph. Additionally I had a high pitch chirp sound when shifting from park into drive(or into neutral for that matter). Dealership checked it out twice with not much results so the 3rd time at 18,000km when I brought it in they were able to see the rpm stutter and hear the sound was getting louder. After 2 days at the shop they said subaru of america decided to change the whole transmission. 4 days later (almost a full week at the shop while I had a loaner). I got a brand new tranny. It rides MUCH smoother through the fake shifts and the stutter and chirp are gone. Good thing it all was under warranty! Also for those that might ask what the actual problem was? even the dealer couldn't figure it out and in fact were not allowed to dig deeper into the tranny as a new one came and the old one was put back in the crate for headquarters to play with.

Goodluck.

I think I may have the same or similar issue as you describe here or maybe closer to what @SkiPro3 describes... I am curious - when you experienced the stutter, did the RPMs jump around a bit? Mine happens predictably around 2000 rpms and will jump a few hundred rpms for just a second. And how were you finally able to get them to notice the issue? Did you take one of the service techs for a drive and show them? I have taken mine in and the techs can't recreate it.

They did not notice it the first time around but when I brought it in again it was able to show up on their tablet when they took it for a test drive. Also yes the RPM fluttered a bit when it happened. On my old outback I had a misfire problem where the dealer said if it happens drive directly to them and do not turn the car off so it will show up in the system(annoying to have to drive directly there I know) but that just makes me think that maybe if nothing is showing up for them now with your car, perhaps when you turn the car off it resets the error? Not sure but just something to ask them. Goodluck.
