Default CVT Trans lag

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. (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!

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?
