Recently I began to notice whenever I slow down, I can hear a very soft whirring sound get lower and lower pitch as the car come to complete stop and it's gone. The sound appears to come from my CVT tranmission, the gear stick area.
Any bros has heard this noise?
-
I noticed this also. Started around 30k.
-
Yup, i got this from 5000km onwards... Asked TCM to check during my 5k service. They claim it's the CVT gears making noise... Cannot do anything... :nonod:
-
So this is normal? I was worried that my cvt tranny may be going soon.., now only 47K..

No, it's not normal. If there is any funny sound or noise, that means something is not right. Since your ride is still under warranty, better bring it to TC for check before it leads to bigger or more serious problem/damage (we can never know). Don't play play, CVT is much more expensive than normal auto transmission.
My ride coming to 4 yrs/90,000km liao but don't have such sound, touch wood!
-
Mine also have this sound when slowing down... like a jet engine sound right??? I tot i read a post some where that this is normal for CVT... i might be wrong..
-
I also experience this whirling down and up sound when travelling low speed slowing down or lightly speeding up, between 10 - 30KM/hr on my 4 AT, this this sound comes on after heavy usage?
Any feedback?
-
Yes, heard this from my CVT too, a subtle sound like jet engine, also when slowing down, and then the sound stops.
some say its the normal sound of CVT.
-
I've experience it also in my my cvt ride too. Can hear it clearly after heavy usage and without turning on the radio. Wondering if it is normal for cvt engine... :confused1:

What's your mileage? Mine 47K. The noise is subtle, can hear it if the radio is not loud.
I did a test, when I stepped the brake to slow down, I switch the gear to neutral. The noise is still there..
-
Aeh swtich to neutral.. CVT still spinning mah.. just that power now transferred from engine to wheels??

Another video on CVT..

The way I can describe is more like a small electric motor spinning down...

Judging from the above video, CVT seems to provide the convenience of automagtic transmission but with the engine brakes of a manual.
Can those CVT Latio owners comment?
Is it true?

There's the usual fine quiet high pitched whirring and then there is the other lower pitched humming/whirring drone. The first sound has been there since the taking delivery of the car. The latter happened a few months back. TCM changed out the a/c compressor and pulleys. Sound went away...

Guess i need to pay a visit to TCM anytime soon...

Sorry for the late reply. Mileage around 60K.

Finally went down to TCM today with two complaints,
1. Squeaky noise from engine compartment when gear is engaged.
Fix : Renew Exhaust Cones
2.Whirring noise during slowing dwon
Fix: A/C compressor change
Parts
1. Bearing Seal
2. BRG Ball
3. Air Con Compressor.
Also top up of FREON gas..
All no charge as under warranty. First day try out, seems the problems have been eradicated.
-
hohoh.. this is bad... looks like need 2 go for check up liao.. may i know which branch u went??
-
thks bro for sharing...went to the last round svc complain abt this noise but all they say is aircon compressor but nvr did anytin....mus go screw them next time round man.... :mad:
-

TP..the SA is Steven.. Wanted to leave a good feedback online, but couldn't find any link to it. Day 2 liao, both noises are gone.

I went in with only my complaint without servicing, probably why they have time to change the A/C compressor. My guess is if complaint during servicing, especially a major one, they may be squeezed for time and give you a temporary fixed if it's not too serious. When I sent in my car at 9am, I got a SMS at around 5pm. So I guess they really took a long time to change the compressor and other fixes.
-
if hear any abnormal noise, better go to TCM quickly.....
especially for aircon compressor....I spent $1.3K to change the aircon compressor + related parts....
since 2nd year of ownership, can hear soft noise from aircon but ignored till warranty over, noise became louder, then LL change from my own pocket...
-
I've just changed my bearing seal at Lok Yang due to squeky noise when gear is engaged. Now the sound is gone. :smile:
Highlight to the SA about the whirring noise when slowing down and says that some latio owners experincing that and got the air-con compressor changed. He told me that they will check the air-con compressor and says that they could not find anything wrong. :mad: He suggest that I highlight this problem again in the next servicing. He further added that currently the machine needed to 'suck the air out' is not available at lok yang as it is sent for repairs. Should i make an appoinment for a test drive with the foreman? I have bad experience taking this option as the the foreman tend to downplay the seriousness of the problem by claiming its normal for Latio cars. Experience that in BT and Ubi. :zipped:
-
I think air-con replacement takes lot of time. I suggest to go with only this complain. Also try other service centre, than lokyang.
I didn't test drive with the technician. Just complain the problem to SA, sign the form and left. Receive SMS, and collect car. Pleasantly surprise when cashier showed the invoice, all NC(no charge)..

Ender, has the whirring sound in your car been rectified?
If the whirring sound is gone when aircon is switched off, then it's due to the aircon compressor. If the whirring sound is still there, then it's something else like worn out bearings, etc.
Recently I got a loud whirring sound whenever I started the engine and there was also whirring sound when I stepped on the gas. Sent my car to the mechanic yesterday. It was found that bearings had worn out/damaged that caused the whirring sound.
My mechanic also told me there was a Cefiro which had the same problem when the car was in Ipoh. The owner decided to drive straight back to SG (with aircon off). When he reached JB, the bearings jammed and the multilink belt snapped. He was considered lucky to have reached JB and towing the car back to SG was still manageable.
So Ender, you use to drive to Genting and other places in MY, better check.
I got the bearings and multilink belt changed yesterday and now the car is very quiet like before.
Big bearing $20
Small bearing $18
Multilink belt $40
Labour $45
Total damage $123, not too expensive and my mind is at peace because I also chiong MY quite often.

You did your repair at TCM or outside workshop?

Outside workshop, naturally. If done at TCM, I would not be surprised if it cost double or more. Anyway, my 3 year/100k warranty had already lapsed. So won't be going to TCM for repair and get chopped. Some outside mechanics are better and much more experienced than those at TCM, cheaper somemore :thumbsup:.

Wahh.. can intro boh?? the price is resonable leh.. all using original or OEM parts?

Just sent in the car to TPY for checking on the whirring sound.... lets see what they come back wif...
