2019 forester cvt shutter
Yes the forester is definitely under warranty. I am trying to do research to see if this is a common issue or perhaps a TSB covering this problem. The issue is intermittent and only occurs when cruise is engaged.
This sounds like a CVT problem alright. Since this is a 19 there have not been a lot of complaints here .....................yet. It is a Subaru so who knows what will pop up in the next few years.
I am experiencing a "shudder" in my 2019 Forester from time to time. it happens when gently accelerating, at highway speed, with the cruise control on and off. it feels herky jerky, like the transmission is losing its grip while the engine revs up slightly... my car is at the dealership right now, and they could not reproduce this today. they did have to update the radio/touchscreen system, and have to replace then driver seat frame due to bad welds, but that part wont be in for three days. they are going to drive it more again tomorrow to check for this shuddering thing it does. i am pretty annoyed...it started doing this right at 6000 miles, immediately after its first oil change. i haven't found much about this after doing numerous and lengthy searches on various forums....
Try setting the eyesight acceleration chacteristics to narmal or adaptive. This should also program the cvt and map the accelerate.
I tried changing eyesight to every combination available. Tried shifting using the paddles and changed the throttle mapping from intuitive to sport and every combination of all these settings and nothing changes. The frustrating part is the shutter is intermittent. The problem may be consistent for a couple of days and then not occur for a week. My dealer is supportive in trying to resolve the problem, they reprogrammed the CVT back to factory specs and it seemed to work correctly for a few day and then the shudder returned. Not sure if the reprogramming helped or it was just a period that that it worked normally. The severity of the shudder changes as well. Sometimes it Is so severe it almost feels like the vehicle is running out of gas and then it will change to a minor hesitation. Very frustrating trying to find the cause when the issues is so intermittent
I picked my Forester up today from the shop, and was told that this is apparently a "known issue" and Subaru us supposed to be putting out an update to correct it, but no ETA is known for the update....which sucks! It happens with the cruise control.....so, at least it isn't the transmission....
