I'm at Vinny Ten Racing right now... they've never heard it before, but they're going to try to replicate it and figure it out.

Subie service center to try next week if VTR can't figure it out.

Everyone, keep posting videos so I can play them all.

No go

They couldn’t replicate or they couldn’t figure out the cause?

Couldn't replicate, but I think I have an idea. Testing tomorrow.

I've posted on this a few times in the "generic" issues thread. I was able to capture this coming out of a left turn recently. I hear it mostly in and out of left turns, but have heard it randomly going straight as well. Confirmed (at least in my situation) NOT linked to LKA/EyeSight status changes or incoming messages on a paired phone.

That engine certainly sounds loud. Is that normal or is it just the recording device making it sound louder?

Well shoot, too bad I'm not near you guys. I am getting really good at anticipating and even (most of the time) replicating it on mine. It does it EVERY single time backing out and leaving our house.

Either that or it's just getting worse for me, lol, eek!

I'll try to get a compilation video up this weekend. I've got probably 10-15 different clips of the tock (one of the best clips being as I'm backing out of the service dept too, lmao

Side note for a new sound: I am even getting some sort of "whurrr" sound as I let up off the gas sometimes too.

I haven't heard anyone talk about this new sound yet and I've never had a turbo before so I'm not sure if this new sound is normal for turbos or not. It does not do it all the time.

Captured "tock" and "whirr" sounds

For anyone else who is also experiencing these noises and having trouble replicating it for your service depts., here you go.

This video includes all the best examples of the weird "tock" sound I have been able to capture thus far. I included some clips of a strange "whirr" sound I've also been hearing under some circumstances. Usually, the whirr sound occurs as I let off the gas, but only sometimes.

Hopefully, this video can help SoA and the Subaru service departments diagnose and figure out what is causing these noises.

So the chirping sound that you hear when going from reverse to drive happens for me as well and you can hear it very pronanced outside the car and the sound is coming from somewhere in the driveline possibly the CVT. It only happens for me when the car is cold and in 1500 rpm high idle mode. If the car is already up to tempture I never here the chirp.

The whirring sounds like the turbo spooling down after you take your foot off the gas?

The tock sound, I've said it before I feel like it's related to the whole target acquisition thing or something like that. Something in the EyeSight suite. It could be acquiring an obstacle or target in front, and then when you turn, the tock is the "target lost" sound? Seems to happen almost always when you're altering your direction, doesn't it?

Could you try disabling lead target acquistion alert or lead target moved indiciator? Maybe that has something to do with it. ****, disable ALL eyesight sounds temporarily and see what happens.

I've thought that the whirring noise might have something to do with the turbo as well. But it only happens sometimes, even when (at least I think) all conditions are the same. And someone in the whirring sound thread mentioned it might be related to the CVT?

I think I'm going to leave the "disable all EyeSight functions" to test out, to someone else with this issue. So far, every time I'm driving, I have our daughter in the car, and turning off those features just seems like a risk I'm not willing to take while she's in the car.

And if the targeting acquisition thing is the issue for the tock noise, why does it only make the sound while turning left? (99% of the time anyway) Plus it seems like it happens more often and even maybe louder while you're turning left and giving it gas (while the suspension is under a load?).

All sorts of scenarios and different conditions. Which is what makes it the random mystery that it is and so frustrating (at least until we figure it out!) :tango_face_wink:

 

[pilot1226]

Oh yeah, sure. But the tock sound "seems" to be electronic - not mechanical. That's why I was suggesting something with the infotainment - either EyeSight or Navigation related. We did determine it is not specific to the navigation-enabled displays, right?

 

[Robert.Mauro]

Mounting a mic or two soon.

Yes, especially since this complaint is sporadically reported on other Subarus with different (or no) navigation systems.

I'm wondering if it's a relay or something in the unit mounted to the driver's side "shock" (strut) tower. I plan on mounting one of my lav mics inside and record when it happens to see if I can at least narrow it down to inside or outside the cabin.

CVT Chirping is totally normal when shifting into drive, etc.

So the chirping sound that you hear when going from reverse to drive happens for me as well and you can hear it very pronanced outside the car and the sound is coming from somewhere in the driveline possibly the CVT. It only happens for me when the car is cold and in 1500 rpm high idle mode. If the car is already up to tempture I never here the chirp.

The chirping sound is totally normal. The pulleys that drive or are driven by the CVT chain are hydraulically filled. This is totally normal on both high torque CVTs (the one mated to the Outback 3.6R's H6 and to the WRX's equipped with a CVT, as well as to the one mated to the 2.4DIT in the Ascents.


From Subaru:

"...the CVT (filling) up both primary and secondary pulleys (causes) this chirping noise and at times a surging until pressure equalizes. Noise is considered normal."

Because of the way the system works, and how long it takes for pressure to drop when the car is off, and the temperature and a variety of other factors, the car may or may not chirp when shifted from Park to Drive. That too is perfectly normal since it's those very conditions that determine if it chirps or not.

That should definitely help narrow down what to look for. Another thing to think about for if it actually is electronic vs mechanical is that sometimes the tock is lower in volume and sometimes it's loud enough to hear over the radio and A/C fans. Which probably doesn't mean anything since if it was electronic I guess it could be at different volumes too. Grrrr!

 

[Rgashton]

Meow I'm starting to think this has something to do with the HVAC system. Could there be air in the system that needs purging or something? Low or too high in freon or whatever they put in there these days?

Because if the fan is on low, I can hear it just fine and it's more or less at a set volume (sometimes louder than other times) and only happens once in a while, still more often turning left. But some days when I just have to have the A/C blasting cause it's dang HOT and humid in Florida, lol, it's as if I've also turned on a percolating coffee pot in the car...

...tock tock tock-tock TOCK TOCK-tock tock-tock...

It just goes crazy and matches the volume of the fans (as the fans get louder the tocks seem to as well). It will then also make the sound just going straight, right, left, sitting still. And I can hear it through the loud A/C fans. And that's why now I think it might be HVAC related.

I haven't tried turning the fan completely off though because we would melt if I tried that right now.

Just wanted to throw this out there. Who knows, maybe one of these theories may strike a eureka moment from one of us and we'll figure this out.

 

[Robert.Mauro]

My fans are almost always on setting one, max face, lower than max to feet. The sound occurs for me whether I am just starting or have already driven for an hour.

Yep us too. I haven't figured out what all the settings mean on the climate controls. But I think ours are set the same as yours. It says AUTO next to the arrows and the horizontal arrow is bigger and the vertical arrow is smaller (they aren't the same size). I'm pretty sure it's always been like that too.

Maybe I'll play around with those settings to see if anything changes.

Someone recently posted to the Ascent FB group stating it is the A/C condensate drain making this noise.

Can you link me to that post please? I don't have Facebook so I'm not sure I'll be able to read it though. Did they have a solution?
