Mine does the same exact thing. I reported the dealer that I could hear a "chirp" and feel a surge.Mine does the same thing and after analyzing when it happens, I think my spidey sense has it figured out.
Mine does it only in the very limited circumstances of starting the car after it has been sitting for hours aka overnight or at the office all day.
When I start the car the engine goes into an overly rich mode to heat up the cat quicker for smog and that means it has a high idle of around 1,600± RPMs. If I engage the car into reverse while it's in the 30 second or so high idle phase I get the squeak.
If I wait there's no squeak. I think it's the torque converter engaging that makes the noise as it jumps into gear.
Could you ask them to cite a source for that information? I've never seen anything like that in any of the Subaru service training materials I've read. As far as I know, the Variator pulley actuators don't drain when dormant, and both pulleys have a substantial spring preload tension even when secondary hydraulic pressure is not present (e.g. when the engine isn't running). "Limp" mode of the CVT relies solely on that spring presssure to prevent Variator chain slip."... 1.5 second initial lag times allows the CVT to fill up both primary and secondary pulleys causing this chirping noise and at times a surging until pressure equalizes ...."
what year and engine you got? (not all gen5 are created equal)I came here and registered for the site specifically to log a "same here".
Same symptom: When cold and shifting into drive, there's a pretty loud squeak the first time I do it. It doesn't seem to occur after that until it's been sitting for hours. My wife never noticed it from inside the car, but I hear it every morning from the garage when I'm sitting at the breakfast table and she leaves for work. I finally got to experience it from inside the car this week and it was pretty subtle. I haven't yet pinpointed if it has any relation to the outside air temp yet but it has been colder here than normal (like 50F or less). Based on the number of complaints here, it seems like there should be a TSB for it.
My 06 Sentra has chirped going from 2nd to 3rd it's whole life and the trans has never let me down. Sitting at 150K, does it mostly when it's cold out.Interesting, I've never heard anything like this from my CVT. A search of the Gen 5 forum turns up just a few additional complaints that are fairly similar (and a couple more that describe different noises when shifting), so seems rare enough that it's hard to imagine it being a common problem. Guess it could just be something that's not likely to bother most people.
