This is great news.

It's been 14 days that they have had mine for the shudder and the power loss. There was still no word on why or how they planned to fix it.

I went to the dealership yesterday afternoon and trade me into another vehicle, which they did. I now have an SL model built in 02/13 with less than 500 miles.

On the note of older models, the loaner they gave me was built in 03/13 and the sales guy who picked it up confirmed to the dealership that he felt the judder.

I really hope Nissan fixes the judder soon.

Good for Nissan.

Those are strong words saying they will "eliminate" the problem.

I wonder if that wording is from Nissan corporate or an individual.

You are correct that all automatic transmissions have certain characteristics that can produce undesirable noises, motions, jerks or hesitations. This particular problem isn't like that.

I'm sure you've read that it feels like going over a rumble strip on a highway. It's not a momentary jerk (like the feeling a transmission makes when it changes gears), nor is it just a noise. It's something that resonates through the chassis and can be both felt and heard. There's a distinct mechanical sensation to it that is unnerving at best. It can be subtle, but sometimes it can be prolonged and pronounced.

I hope that makes it more clear what people are concerned about. The earlier TSB to address this issue explained that it was actually a slip of the drive chain due to insufficient tension. Having experienced this many times in the 6000 miles I've put on my PF, I honestly do believe that's what is happening here. And if that's true, that's a lot of otherwise unnecessary friction/strain that will very likely shorten the service life of this transmission. Having driven other CVTs, namely my wife's Subaru, I can tell you that this is not a normal characteristic of a CVT. Given that Nissan has much more mass-market experience with CVTs than Subaru, I find it dumbfounding that they could have released this vehicle with such a significant and prevalent problem.

I agree with this.

I am dumbfounded on two levels. How such a significant issue would pass testing.

How a quality company like Nissan could allow this to happen.

Toyota had a huge misstep with the accelerator problem on a lot of their vehicles. I guess it can happen to any car company.

I've just found this forum. Thanks, its a support group for first time CVT byers

I was one of the first 2013 Pathfinders purchased in my area. I was also one of the first in for the reprogramming. I too have the symptoms still, but mine are far more intermittent than some described here. We have noticed it more on a recent road trip where we drove a few hours at a time.

I have spoken to Nissan, they would not advise me either way on driving it or not driving it. After a lot of research we settled on this vehicle and really do love it. I am taking a optimistic approach on the quality of Nissan and that this is not a new technology for them (based on so many other models having problem free CVT's). Let us hope they have a repair for this soon because it is an awesome vehicle otherwise.

I'll check back here on a regular basis to keep informed. Great forum, thank-you.

100% this.

After having the new , replacement truck for 2 days, I can definitely feel the normal operation of the new CVT transmission and how it differs from a traditional transmission. There are pulls and some shakes, but it is very different from the judder. These are very small and hardly noticeable. The only reason I notice them at all is probably because I just got out of one that had a shudder problem and now I'm tuned into every little thing that happens while driving.

I'm with you. I can't imagine driving anything else now, I am so in love with this truck. I have found this forum to be a great source of info, also. Hopefully there is a fix soon!

Good news.

Seeing how this problem is so common Nissan has to be aware of it, I bet they're working on something at the moment. Usually for something like this they have to call in their engineers to diagnose it as all dealerships tech can do is replace things.

Hopefully some TSB will pop up with a fix mentioned and everyone can start enjoying their PF's once again!
