My '17 Premium is my first CVT. I purchased it with the expectation of it being a solid, reliable, utilitarian vehicle. The CVT attracted me because of it's ability to optimized gas mileage. Living in a very rural area and being a frugal sort, I have developed driving habits that also optimizes my mpg. 90% of my driving is in rolling foothills/mountains, on State Routes where speeds are 60 mph or less. My conservative pedal foot and the CVT seemed to be nicely matched. No complaints.

After 1k break-in I have been manually calculating my mpg to see how accurate the vehicle readout is. Yesterday's math was 185 miles on 5.34 gallons, 34.6 mpg. Vehicle was estimating 35.3 mph. Now I am really getting to like the CVT, and the engine.

So put me into the "love it" column.

My 17' Preemi gives me 25, ( I drive a max efficiency) up from 22 just after I got it. So you are saying mileage will go up after 1k break in ? Didn't know that ! Wonder why the dealer didn't tell me that.
So you dont have the unnerving 2-3 second delay when you push the accelerator to move front ?

No, if I apply soft, steady, increasing pressure to the pedal. It is different than any other AT I have experienced, but I quickly developed a feel for it. Four months and 6,500 miles, the driving experience is ....smoooth.

Well its not like I slam on the gas either...As gentle as I press it it still takes a while.

So I took it to the dealer's yesterday who did a whole bunch of tests and gave a report and said wait for the break in period (1k?) and then bring it in

It is very sporadic, in the sense sometimes it kicks in immediately sometimes delayed.

If it were me I'd disconnect the battery's negative post, leave it off for an hour or so, then reconnect it securely. When ready to drive next... while keeping feet off the gas pedal... start engine and let it idle until revs drop then drive smoothly and normally until fully warmed up.

Some argue this does nothing productive. My experience disagrees. It will, however, mean you may have to redo some things, like radio channels, etc. On my '14 FXT (and others) I found it to change oddities of operation... such as you describe.

Other than the inconvenience there are no downsides to disconnecting the battery to reset things.

Haah..ok I will try that..I will try anything to alleviate that delay lol

dont they have a solution for that power reset thing yet ?? Cars these days have all the latest tech but not something which my alarm clock has...doesn't have be heavy duty either ..just for electronics...anyway my 10yr old son who is better n me at setting electronics will just have to do it all over again (which he enjoys - specially inputting bdays..which I find stupid-in a car...lol)

So disconnecting the battery didn't make a difference, (still a 2s pause after reversing)...just made my son mad he had to re-enter everything :) One thing surprising though - The superfluous birthday list remained saved...go figure !

It will go away over time or be less obvious as time goes on, my 14 did it too then it was non existent.

Hi All!

I am new here but not new to Subaru's or their CVT's. A Little build up first:
We've owned:
2005 Saab 92x Linear (really an Imprezza) with auto. No bearing here, just stating fatcs.
2013 XV Crosstrek 2.0i Limited with CVT.
2014 Imprezza Base model with CVT.
2016 Crosstrek 2.0i Premium with CVT.
2016 Imprezza Sport with CVT.

Due to family changes, we had to consolidate into one new car suddenly.

Traded the two 2016 for a 2017 Forester 2.5i Premium last October.

Since then the Forester has had this constant shuddering in the transmission. It always happens when you are holding a steady speed generally around 30 - 40 MPH or 60-70 MPH. At low speeds it's a small shudder, but at higher speeds it's sort of alarming. In the snow or ice it's damned terrifying. You think your skidding at some points but you are not.

I took it back to the dealer at 285 miles and they said it is operating as designed. Then the SA told me his wife's 2017 Forester 2.5i also does this behavior. He said put some miles on it before overreacting.

OK, so e have now over 5K miles and if anything it's gotten worse.. Hell, I even went back to the dealer and test drove another new Forester, the same as ours, and it acted the same way!

No it's not that it's a CVT and I am unused to them. I have never had any of the Subaru CVT transmissions act like this. But then I have never had a Forester before either.

Is any other 2017 Forester 2.5i drivers out there experiencing this issue?

Bill

Not to the degree you are describing, but yes, my 2017 is jerky at low RPM, my 2015 did not have this problem.
