I'm finding that the CVT on my kizashi is shifting into high gear way too early. Like 5th gear at 20mph and 6th gear by 30mph. It's causing the car to vibrate and lug like a manual trans would do if you put into too high a gear at a low speed.

Does anyone have this problem and or know if their is a TSB or something to fix this?

Thanks!

There are a few owners around that have complained about this, including me.

Suzuki Australia describe it as a "characteristic" of the car and basicly "stiff s**t" we can't do anything about it.

Unfortunately they describe the Kizashi in their advertising as an "exceptional luxury sedan" with a "smooth, powerful" engine. Neither statement gels with the actual experience of driving the Kizashi CVT gently. :mad:(The other big complaint is the fuel consumption which is nowhere near the claimed figure!)

It's frustrating when the rest of the car is so good!

All of the reviews I read before buying my Kizashi made no comment about the vibration problem, but I found this one afterwards which seems to describe the problem!

2010 Suzuki Kizashi XL Sedan | GoAuto - Our Opinion

It seems to me that Suzuki have geared the CVT way too high (top is higher on the CVT than the manual) and, as you said, programmed it to change up to early when driven gently. I can only assume this was to try and get better fuel consumption as it definately detracts from the diving experience!

I hope that Suzuki come out with a reprogram of the CVT to improve the situation!

The SX4 CVT does it too. It bucks pretty violently sometimes too. CVT is a good idea but POORLY executed by Suzuki in both the Kizashi or SX4. Unfortunately it IS a characterisitc and there are no updates available to fix it.

It's a CVT transmission it Does Not shift. If your light on the gas pedal the rubberbandtrans unwinds rather quickly. Use your paddle shifter or manual mode floor shifter to simulate upshifts keeping the car in the power band you want.

I'm aware that it doesn't "shift" like a traditional automatic transmission. I know I can use the manual mode to force the cvt to stay in a lower gear. Just wish I could I keep it in auto mode and accelerate smoothly with out using the shifter.

Well your now learning the feel of this type transmission and they all work about the same from a MINI to a Toyata. They are what they are and you'll not find me buying any car with that type of transmission for my daily driver. It doesn't bother my wife so all is good. Oh the CVT tranamission does not have gears like 1st or 6th or any in between.

Sorry. I should have chosen my words more carefully. In referring to gears I was referring to the artificial gear ranges the manual mode of the CVT has preprogrammed. I know it's a rubber band type deal. My point is that it's moving into the higher gearing at too low an rpm. Had a Nissan Altima with the cvt that didn't do this at all. CVT's may all operate the same, but they are not all geared the same.

Still the Altima feels like it has a sluggish CVT transmision in it, and it does. By far the most hideous CVT type trans is in the Mini Cooper .. They are only hideous when they are not broken. They are great when they are in the Mini service dept because now you have a reason not to drive the thing.

Depending which motor the Altima had has an effect too. The Suzuki 2.4L has zero torque in the low rpm band which is why it lugs like that when the transmission gears itself high at low speeds. If the Altima had a the 3.5L or whatever they are now they have a much better power band.

I know all this still doesn't fix the problem. All it would take is a relfash of the TCM...who knows maybe the issue is being looked into?

I have a sneaking suspicion that this is one way that Suzuki achieved their "class leading" low fuel consumption figure (only achievable under specific test conditions, not real world driving!). In fact I find the fuel consumption to be poor compared to my last 2 cars (Mazda 6), even though the Mazda was supposed to be more thirsty. If this is the case they won't make the change, which is a great pity as it would make for a much nicer car to drive. In real world conditions I doubt it would make much difference to the actual fuel consumption, but they wouldn't be able to claim 7.9L/100km average!

Driving an automatic transmission is bad enough then driving any type of CVT or what ever name one pins on it makes it just plain nasty. That said I'm only speaking for myself. My wife loves her Kiza and has nothing bad to say about the trans. If I bought a Kiza for myself the fix would be a manual....

We've had our Kizashi for a month now and done 1000km. I am getting used to the CVT and don't mind it now. Using the throttle can balance the acceleration nicely, and I found that moderating the throttle under hard acceleration gave as good a performance as using the paddle shifters or tip-tronic.

Mine pulls the high gearing from only 1200rpm on level ground and while it does sound too low, I think it's more sound and feel rather than actual performance.

I'm getting mid to high nine's around town but did achieve 6.6l/100km on the freeway. The 7.9 figure is supposed to be an average of urban and rural driving and with more open road driving I think it is achievable. I'll find out when I get to take it on its first long trip. I do drive with the climate air on all the time though and of course that will affect economy some.

Kizashi 2012 CVT Transmission

I just purchased a 2012 Kizashi and didn’t really notice anything on my test drive. After buying the car and using it in my every day driving to work and home. I find that whenever I drive in automatic the car drives smooth up to 20 MPH but between 20MPH and 35MPH it struggles to pick up speed and the engine get very loud. Almost like if you're driving in manual and you forget to shift while going faster. I have taken it to the dealer and they say it’s fine. A CVT engine should be a smooth gradual transition while moving at faster speeds. It should not even be noticeable that the engine is picking up speed. The engine should be almost quiet and smooth. My car at 20MPH begins to slow and shake a little and it’s really bad when trying to go up hills. It’s obvious something needs to be reprogrammed but Suzuki wants to keep with the line “it’s a CVT engine”. I did not pay $20k for a car to drive like an $8k car. In no way is this normal.
I am going to keep calling and calling until someone admits the issue and does something about it. If you are having the same issues join me in adding the pressure. I’ll take this all the way to Japan if I have to. Here is some helpful contact information.

2012 Kizashi CVT Transmission issues

I am new to Suzuki and very concerned that after calling Suzuki Corp and my local dealer that I had to research to find recalls with my new 2012 Kizashi. That troubles me. I made a post of the CVT transmission not running smoothly in automatic. At 20 to 35 MPH the engine stalls and seems to shift down causing the engine to struggle to pick up normal speed. This is a transmission issue. After researching this I was able to find this web site.

http://www.iseecars.com/car-problems/suzuki-problems

Which lead me to National Highway Traffic Safety Administration (NHTSA) 888-327-4236
They listed a Technical Service Bulletin 2011/10/11 NHTSA #: 10042157 Service Bulletin #: SC-57-R-1. If you call Suzuki their recall # CSP-10B20. The recall is POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM, PCM): SUZUKI: ON CERTAIN MY 2012 VEHICLES (SX4/KIZASHI) EQUIPPED WITH CONTINUOUSLY VARIABLE TRANSMISSION (CVT), A VOLUNTARY EMISSION CAMPAIGN HAS BEEN CONDUCTED FROM MANUFACTURER.
I called the dealer and they insist they have never heard of this issue and for all they know the car is running just fine. Well here is the definition of a CVT Transmission is not my understanding of what I have read and come to learn that it’s supposed to help the car pick up speed and accelerate giving a smooth drive. Not my new car.
To find the dealer and the manufacture was reluctant to openly give me this information because it’s related to the transmission and can become costly to them as a new car to replace the full transmission and in some cases the whole engine. There is a defect some place. Once I called the NHTSA and received the recall number. I called Suzuki and they remembered after me calling 4 times about his issue that they issued a recall update to the CVT transmission. They say it’s related to an SQ update to the TCP/PCM. So this recall is to give an update to the transmissions computer system to help give it that smooth ride. I am going to take it in to get this update and hope it fixes this issue. I am not a happy Suzuki customer to find this serious issue was not openly offered as a resolution to me as a customer by mail, email, phone or any form of communication. Not even after I called them to explain my issue. This is not how your auto manufacture should represent us as customers spending over $20k for their car.

Hi Madboy, well done!!
It seems that Suzuki's customer service is the same in the US as in Australia, not that hot (I won't be buying another Suzuki).:mad:
I will be very interested to hear the outcome of your "software update" as will many others.
Like you, I didn't notice anything particularly bad on my test drives, but I was driving rather "enthusiastically" and the problem (at least my problem) is only apparent when driving the car gently.
I am sure it is down to programming of the CVT and could be quite easilly fixed. Once again really interested to hear a report back from you.

Suzuki Kizashi 2012 SQ CVT Transmission Reprograming

Suzuki Kizashi 2012 SQ CVT Transmission Reprograming
I took the car to the dealer and they test drove it and said everything is working fine as they always say. I had to ask them to the SQ CVT transmission reprogramming. This is an update to the computer software for the transmission issued by Suzuki. So they went back to find there was an update available. I had to force them to do the update. After the update my car now runs normal with no lag or slowness to the engine as it did before. The car feels like a Porsche now. It’s powerful and very quick and fast and the CVT engine is now smooth. It’s like night and day to how the car was driving. I felt like I was driving an $8k car and now it feels like a $50k sports car, Amazing. I am happy now but still bothered my 2012 does not have standard AUX or Bluetooth.
This is your car and a CVT engine should run much better than a regular automatic engine. It should be smooth all the time. If your car is running slow or feels different trust me get the update. I don’t know what update was done because my sound system sounds amazing also. Before it was horrible and now it’s sounds amazing.

Thanks for the feedback, it sounds very encouraging! My only reservation is that my Kizashi is one of the early ones (2010/11 build I think), and I wonder if the dealer will say that the update is only for the 2012!:(

Kudos to madboy!

My 2012 SX4 has the same RPM change when I least want it!!! Right at 20 mph like some others have said. Then when I press on the gas to compensate, it rev's too high. What an annoyance! Mine doesn't shake when the engine lugs down but its still just not right. :mad:

I just want smooth acceleration without having to play games with the gas pedal to do it. :p

I can only assume that this SQ CVT update (is that what I ask for?) will work for my SX4. If your dealer found the update then it must be available to other dealers as well?
