Engine noise on deceleration?


Asked by Dec 31, 2015 at 01:42 PM about the 2016 Subaru Forester 2.5i Premium

Question type: Maintenance & Repair

I purchased a new 2016 Subaru Forester two months ago, and as
someone new to CVT engines, I learned that the engine can sound a little
different from conventional engines, with a little more whine. One thing that
I have noticed though is that there is a brief but pronounced whistle/whirling
noise when the car is decelerating between around 10 mph to a complete
stop. While it is brief, it is definitely audible and once I heard it I can’t stop
noticing it, even with the radio on. If I am slowly cruising around a parking
lot it is almost constant (along with a very light ticking sound). Is this normal
for a CVT engine?

I test drove a different Forester at the dealer (as I chose a different color)
and don’t remember hearing it, though it doesn’t mean it wasn’t there. The
sound seems to come from the engine and not the brakes.  I guess I can
live with the noise better if I knew it was by design rather than a fault. I
asked a service tech when I picked up my license plates but got a vague
response and while I will ask again when I bring it in for normal 6 month
service I just want to try to understand better now. Thank you!

The whine is probably normal but the ticking may be valve noise. If I were you I would seriously reconsider buying a new Subaru due to the oil consumption issue.

You're conflating the engine sound and the CVT sound, making a diagnosis from afar impossible. The motor is most probably ok, but I'd get a good Subie ear to listen to that CVT. Very LOW- pitched halting road sound is from the all-season tires, but high- pitched can be the CVT. Ticking at idle is just Subie's horizontally- opposed motor's large surface area to volume ratio allowing it to sound like a one-man band.
