jsmythe Posted July 25, 2015 Share Posted July 25, 2015 I have just come back from a long road trip up to Vt and Montreal, over 1k miles. Mix of mountain roads, long highways, and some unpaved roads. I noticed driving it today that there was a low rumble, what I first thought to be road noise but different pavement didn't affect it. It starts up at speeds greater than 35mph and remains constant. I flipped it into neutral and the noise was still there. I was wondering if it's already a wheel bearing at only 7K miles on the ODO. The sound doesn't change pitch with speed though. It's almost like an electric motor that's loose on it's mount generating some reverberation. Never encountered anything quite like this on any other cars which include a Forester and an Impreza. There's lots of pebbles in the tire threads and I will work on them tomorrow but I think those wouldn't be it. Ideas would be welcome... Link to comment Share on other sites More sharing options...

jsmythe Posted July 26, 2015 Author Share Posted July 26, 2015 i know,kinda disappointing at 7k miles. our 2005 impreza and 2006 forester both ran to 50k with just oil changes. Link to comment Share on other sites More sharing options...
Yoda_One Posted July 26, 2015 Share Posted July 26, 2015 Check to see if you have debris in the tire threads. Laughing at Oneself and with Other is good for the Soul Link to comment Share on other sites More sharing options...
jsmythe Posted July 28, 2015 Author Share Posted July 28, 2015 spent time cleaning out pebbles from the tires, i didn't really think that was it and it wasn't. i drove around trying to isolate it some more and noticed that it definitely starts at around 35mph. it sounds like an electric motor purring, the pitch does not change with speed. i don't know if it was there before and just got worse. my wife says she can't hear it :-(.

Cuttlefish Posted July 28, 2015 Share Posted July 28, 2015 Sounds like the tires need to be rebalanced. Did you hit a huge pot hole? Link to comment Share on other sites More sharing options...
jsmythe Posted July 29, 2015 Author Share Posted July 29, 2015 Sounds like the tires need to be rebalanced. Did you hit a huge pot hole? No, but I did drive around unpaved roads. I am having them rotated and force balanced anyway, so let's see what that does. Link to comment Share on other sites More sharing options...
jsmythe Posted August 2, 2015 Author Share Posted August 2, 2015 Having listened to it at length on the highway, the best way I can describe it is a muted motorboat sound. When I googled, I saw a number of hits referencing the sound the CVT is prone to making. Has anyone else noticed this yet? Link to comment Share on other sites More sharing options...
Rick Grahn Posted August 2, 2015 Share Posted August 2, 2015 Having listened to it at length on the highway, the best way I can describe it is a muted motorboat sound. When I googled, I saw a number of hits referencing the sound the CVT is prone to making. Has anyone else noticed this yet? I have a 2015 and have had the exact same symptoms. Had to have 1 set of wheel bearings replaced at 5,000 miles and 2 additional at 17,000 miles. Dealer said "must have gotten a bad batch of wheel bearings." Forgive me if I'm wrong, but I will go out on a limb and pretty much guarantee that is what the problem is. One last thing you can do to rule out the CVT might be to get to speed (mine was noticeable above 42 MPH) and then shift into neutral. Engine revved down but noise (and vibration) stayed the same. Had the tech ride with me and he heard it (and felt it) right away. Link to comment Share on other sites More sharing options...
waterpumper Posted August 3, 2015 Share Posted August 3, 2015 Same issue here. 2015 Legacy 3.6R Ltd., with just 4K miles on it. Questioned the dealer several times without result. Sound is most intrusive between 30 and 40 mph. The dealer has contacted Subaru engineering to put my complaint on record for future reference. Tire noise, wheel bearings and CVT issues have all been discussed, and every tech in the shop has ridden along with me... Link to comment Share on other sites More sharing options...
jsmythe Posted August 3, 2015 Author Share Posted August 3, 2015 I have had wheel bearing issues on our 06 Forester. It's not anything like that - I have popped it into neutral at speed and the noise was the same. The sound starts at around 30 and there are certain situations when it does get louder. At highway speeds, 65+mph, it got a little more pronounced but seemed less on the way back. Interesting that both of your cars are 3.6's with the higher output motors. I can say that this definitely started after I drove up and down the mountains in Vermont. Maybe the CVT's get stressed? Link to comment Share on other sites More sharing options...
GTEASER Posted August 3, 2015 Share Posted August 3, 2015 Have axles and drive shaft been discussed or looked at? Those can cause rumbling or humming noises if a CV joint, universal joint, or carrier bearing is going bad.

jsmythe Posted August 3, 2015 Author Share Posted August 3, 2015 i am gathering ammunition before talking to a service advisor about it. "motorboating" seems to be the universal description for CVT noise / behavior. Link to comment Share on other sites More sharing options...

Rick Grahn Posted August 26, 2015 Share Posted August 26, 2015 So whatever happened with this? What was the issue (if you don't mind sharing)? Link to comment Share on other sites More sharing options...
jsmythe Posted August 26, 2015 Author Share Posted August 26, 2015 Have yet to schedule with the dealership. I realized I have a list of little things they need to address on top of this and I'll need a loaner. They have been slow to respond. -CVT (suspect) sound - TSB etc -GPS Malfunction - no voice guidance, keeps losing settings -Sticking rear seat release -Loose Backup Camera With only 7K on the ODO, I'm kinda disappointed in the build quality. The car also feels a lot "looser" than when I first drove it home. Seriously thinking about trading it in. Link to comment Share on other sites More sharing options...
staygrippin52 Posted August 27, 2015 Share Posted August 27, 2015 I had the same problem youre describing and they are replacing my rear differential(they said it was blown)...i would take it in they said I was lucky because the axle could have fallen out of the car.

waldguy Posted August 27, 2015 Share Posted August 27, 2015 Read a forum like this and you're going to get a skewed idea about the problems. This rather informal poll suggests that most visits for warranty work are minor. In the first 3 months, 2/3 don't visit the dealer for warranty. http://legacygt.com/forums/showthread.php/number-repair-visits-warranty-work-240169.html?t=240169&highlight=number+visits+warranty Link to comment Share on other sites More sharing options...
jsmythe Posted August 28, 2015 Author Share Posted August 28, 2015 I wonder if I have to put back the old RSB as I have the 19mm in there. They could play games with me and point to that as the culprit!!! PS. FWIW have 2 other Subies, an 05 Impreza and an 06 Forester, both relatively problem free until 50k, still only standard maintenance items. Link to comment Share on other sites More sharing options...
securityguy Posted August 28, 2015 Share Posted August 28, 2015 To be honest...I seriously doubt any would notice the swap from a stock 16mm to a Subaru OEM 19mm. Link to comment Share on other sites More sharing options...

PS. FWIW have 2 other Subies, an 05 Impreza and an 06 Forester, both relatively problem free until 50k, still only standard maintenance items. Dealer could pull crap like that, but a larger rsb would vibrate less if anything and prevent other sway, flex, vibration, etc. Link to comment Share on other sites More sharing options...
