Whistle kind of noise
2013 impreza 2.0 cvt 140k. Some kind of whistle noice
coming from the car when driving, gets louder when let of
gas. Noice go away when put in neutral while driving???
Any clue what it could be?
Car shifting fine
Check for vacuum leaks.
Wouldn't the noise come if the car is in park if it's a vacuum leak?
Driving creates more air flow through the engine. Just a guess with little to go on.
It gets louder when car is engine braking
May be within "normal" range for the CVT "whine/groan/moan" continuum, as they're louder in the harder working 2.0 Imps than the 2.5 Leg/OBs. If progressively getting worse you'll need a new CVT, as it probably has a worn internal bearing. Change its CVT fluid ($100) first, if you haven't yet. Any CVT synth is ok.
So took it to the dealer thought fluid change will make it a bit quite they ending up telling me It won't and will need to replace the trany. And the reason thy told me was because thrs a "band"inside the tranny which will go bad if drive continuesly everyday for same amount of miles. Which i do drive on the highway 100 miles everyday. So they told me its out of warranty and i have to pay $7500 out of my pocket. So i got home and called the subaru corporate office and threatened to sue them and they ending up putting brand new tranny. They should really but a recall on them cvts since dealers cant even fix the transmission. These cvts will go bad after 100k miles. What a shame !!
Thanks for sharing. Since most 100k+ CVTs run just fine, it's not clear that failures are correlated with use or bearing failure. It's just too idiosyncratic right now....
That is a new one. Transmissions that fail because of commuting the same distance every day.
