Default 2013 CVT is 'shifting'?

Hello,
My wife's 2013 SX4 LE is doing something a bit weird when I drive it.

The vehicle has 59,000 miles and I feel it is in good condition and I am a moderate driver, I do not floor it. However, when accelerating, at around 20mph there is a noticeable 'down shift' that can be felt. there is no change in RPM.

My neighbor down the street is a pro mechanic for many years and he was sure this is not a CVT car when he drove it. I am sure this is not an actual shift, but something is weird. It does not always do this, sometimes under accelerating the 'shift' does not happen and the feeling in the engine/trans is smooth.

I am not sure how better to explain this, but I am sure I cannot record a video or anything on this.

I was even thinking maybe the rear engine mount is loose and when accelerating, the engine moves and then drops back at a certain RPM. At only 59k I'm not sure this could be the case however.

Any ideas?

OK. Details please! WHere are you ? what engine ? YoU are talking miles....so, the only place in the world is the USA...but please confirm. THere are several versions of this car in the world that exists outside.....and I have doubts about this pro mechanic....and I.m sure you can record a video (with sound) of this, pointing at the RPM and speed.

IN acceleration, the entire engine and transmission unit would tend to rotate in the opposite direction of the wheels....so the front of the unit would tend to go up....

Thank you LMP, this is helpful. I did not think of it that way.

For additional information, I live in Clearwater FL, I bought the vehicle with 51k, it is now 59k. We put new tires when we bought it and a 4 wheel alignment. I have been changing the oil with semi synthetic every 5k miles since.

The mounts have a bit of wear but not terribly bad. The engine is the 2.0... Forgive me, I believe it is the only one for that that year which is a 1,995 cc (121.7 cu in) (https://en.wikipedia.org/wiki/Suzuki_SX4#Engines)

My wife is not heavy footed, neither am I as I stated.

The 'down shift' that I mentioned is just because I did not know how else to describe it. It's like a movement in the power train. It can also be described like how at highway speeds, most cars seem to be shifting into the final gear, but this is actually a torque converter lockup, it feels just like that, but no decrease in rpm since it's a CVT.

Also it is just not something that is visible on the rpm gauge, neither is there a sound or anything. I can only feel it by driving it.

If this does not sound familiar, I can check the mounts and maybe change out the fluid soon as it's nearing 60k, etc. Thanks for any ideas.

YEah in North AMerica you see only the 2.0...(either the J20A or B, depending on the years) but in other countries, there are 1.6 and diesel engines...hence the need to know the place, generally, and engine type. The only hint in your case was the mph....and the CVT that, I think, is not used with other engines.
Notice that Suzuki does not mention changing the CVT fluid..just verify..of course nothing against it.. However it has been reported on this or other Suzuki forum that last years CVT (late2012 and 2013) were chineese built and reported with problems, like chain cogs disintegrating , causing sporadic slippage, and throwing metal particles that can be seen in the fluid...so while SUzuki manual does not dictate changing the fluid, doing it might reveal an unwanted condition.....of course, metal particles would indicate more than changing fluid....

Here's your confirmation...
https://www.jatco.co.jp/english/rele...70628_817.html

Milestones in JATCO (Guangzhou) Automatic Transmission Ltd.s first ten years
2009 Production commences of JF011E CVT for medium FF vehicles

This doesn't mean however that the transmissions are necessarily bad, IMHO.

Any idea if the Pennzoil Platinum CVT fluid is compatible?

most of the JATCO transmissions in Nissan and Suzuki are chinese sourced, made there under licence to the Japan Auto Trans COmpany which is owned by Nissan. Nissan do manufacture units in Japan, but the majority are Chinese made these days due to numbers being made. Some early units did have issues but this has now been sorted.

I still don't like CVT's, but i'm old school. DAF tried them in the 50's and gave them up as a hiding to nowhere due to drive belt failures and control system issues. Strange how the units these days still have the same problems.

What you are likely feeling is a pressure change as the drive belt "downshifts" and the auto "upshifts" into the next "range". You generally feel this as a "seat of the pants" "what was that?" sort of thing, no rev change is usually evident.

Yrs ago many owners complained that the transmission was not shifting, and so through the magic of software, the manufacturers induced a bump to simulate a shift.. depending on the load/torque..
