Help needed from 50-60,000Km CVT latio owners

[iagree]

hi Garitzz

u are good. thanks.

[iagree]

mine also used 05 CVT, just cross 50k no problem on pickup (maybe I get used to it). It was a bit slow at the low end when I first got it last year but that is cvt nature. Then VS and spark VS it, no problem till now. Overtaking on HW is ok too. Having said that, there is no problem for 05 stock cvt. It is very buttery smooth to drive if you have the time.

hi skxly & ying

i think it is depending on the driver & heng suay of the car....
bo pian one.

i am going jb later.

regards.

Sorry guys for a late reply. Was bogged down by work to check.

FYI all the car no power means its a struggle to move...i read about the Taka experience yes...i think mine is like that

My CVT gearbox both changed during warranty. after last change, TCM inform me that warranty will be extended for another year from last change for the gearbox.

I have service with TCM since day one, & have 2 boys one a 3 yr old son & anoter who is one year  plus..both are in baby seats...i think my driving style can be described as easy non aggressive.

Changing gearboxes, having kids in the car & maybe trying to keep the car to reduce costs are top of min when i drive...nope no WRX/rally style driving

I need to read the rest of the posts to answer more questions

I am looking forward to a meet up to test the car.

Not to alarm the rest...i think the car is good, obviously my experience with it not great.

Seems some here face the same issues.

Having a community like this helps greatly as when making a point to TCM those lucky to have a normal performing car can be the voice for the est of us.

I paid close to $70K after interest for the car, most of us here pay a lot for the car...if it ain't working to specs the manufacturers should try to fix what is broken...

Hi Sambal,

Your #2 point looks serious. When you say at traffic light cannot move, do you mean the car literally refuse to move when you step on the accelerator, and then you have the step it harder than normal to get the car moving?

>>Power loss...really have to step & rev up...

Your #4 is not quite understandable. When turning, car no power... did u step hard enough?

>>when executing the turn seems the car is the most tartdy when starting from a stop

Your #3 symptoms i seems to be experiencing. I am into about 3 weeks of ownership of a CVT latio. Year 2006  manufactured. Bought it second hand. I read about the CVT gearbox problem for 2005 CVT Latio prior to purchasing, so i bought a end 2006 one, but still i seems to have problem. Really really not sure if there is indeed a problem somewhere or it is how a normal cvt gearbox will perform. If it is the latter then i am really disappointed. Should have bought a 4AT. 

>>>sorry just feels uneven..sometime no power then power surge engine revs up

hi sambal

do u always 'cheong' heavyfooted?

regards.

No heavy foot...CVT changed during the warranty period. Once changed the warranty for the changed part is extended for 1 year

[Sambal]

Test who's??

Mine is available folks

[iagree]

hi sambal

gd info.
after chg, the wrty ext one more year for that part. song....
thanks.

Sambal,

Since you have changed CVT twice, the intermittent poor response at traffic light shouldn't be due to the CVT. Can it be the ECM (Engine Control Module) as it controls the power output or the TCM (Transmission Control Module) which selects the Gear Ratio. These electronics parts do break down and causes intermittent problems. Can get Tan Chong Motors to reset these modules and see if it helps.

i also suspect the preblem is not the CVT. Can try ECU programing right away haha

hi ying

ECU aso we can program ourselves meh?

[Ying]

no lah, pay Harmony to reprogam it lah

[iagree]

no lah, pay Harmony to reprogam it lah

Hi Ying,

Harmony ?

[Ying]

ECU programing

[Sambal]

Thanks Ying & Chansk

Will see what the TCM folks have to say about ECU change reprogram

Last gear chage they said they reset the ECU which is needed after all gearbox changes.

Maybe need to change the whole unit i guess

After the fourth visit, at last an expert service guy at TC Ubi test drove the car with me and agree that the car is not responsive. Think he reset the ECM and found it doesn't help and thereafter changed the ECM. After I collected my car, I can immediately feels that my car responsiveness have returned. Just a gradual push on the accelerator and the car zooms off and there are no more dead bands.

what is ecm??

[chansk]

ECM - Engine Control Module. The Brain of the Car. Its an electronic circuit board with CPU, Memory.
TCM - Transmission Control Module. Sense car speed and select transmission gear.

Ok. I have my story too. My car currently at 45K mileage. Around 35+ period, a numerous problems with my CVT ride.

Below are my fair shares:

 - Rear drum brake knocking sound with slight braking (Renew drum brake assembly)
 - Loud humming sound from aircon compressor (Renew compressor and refill freon gas)
 - Knocking sound from steerting (Renew steering shaft & snap ring)
 - Engine pinging (Renew ECM)
 - Fuel guage not accurate (Renew fuel float)
 - Engine vibration & knocking sound when accelerate (Renew engine mounting insulator)
 - Power loss - (Renew CVT transmission assembly)
 - Belt noise - (Renew belt shaft, bracket, pulley & retension belt)

Up to date, I still having the engine pinging and knocking sound when accelerate. I will need to go and bug them again. I am not sure if it's just my car only or it is normal since I do not have any other CVT Latio to compare with.

I have just hit 50k. no major problems except @ 40k changed alternater belt(ticking sound when u on engine early morning) and recently, my SA told me aircon compressor and bracket need to change(some light whirring sound) to be honest, pretty happy so far.

[whattafarck]

very seldom have i read threads with this much interest....to the point...its makin me a bit nervous!
me driving a 2007 LS..just done the 25k servicing...no problems so far..
only flat battery in first 4 months after taking the car..(FOC exchange)
but the experiences the rest of you are sharing here ..at least makes me prepared of wat to expect...but i really hope all is fine lah....
