By popular demand, attached to this post you will find the TSBs pertaining to the so-called "shudder" or "judder" problem experienced on 2013-2014 Pathfinders. If any additional TSBs are posted, I'll be sure to update them here.

is it possible to have all 3 TSBs active on one vehicle?
No, #02 was for units built over a year ago that had the chain tear up the internals before they could reprogram it. The last one, 086, is the most recent and it supposedly covers "all" shudder/judder problems.

Which is correct 18mph or 5 mph?

I am in Calgary so sometimes I dont know if its due to Shudder or ice on the road.

I need to find a clean road to simulate this.

So in order to simulate this i need to place my car at around 8 kph to 56 kph plus 10% throttle. Correct ???

Do i need to maintain a constant speed or not ???

Can someone please enumerate the Method to simulate this?

My dealership always ask me to bring my car and with the Technician sitting beside me, they want me to simulate it. So many times i complain about this shudder and the same reply i got "Please simulate it".... and i am having a hard time to replicate it.

thank you PF talk member.

You touched on exactly why the Judder is such a difficult problem - you can't generally simulate it at will. However, your dealer should have a TSB that tells them exactly what to do, and also a troubleshooting flowchart. You shouldn't have to do anything other than to tell them that you're having the problem.

If they are putting the onus on you, then it's time to find a different dealer (and make it clear to them that you're taking your business elsewhere).

Anyway, the judder typically happens between 5-30MPH. Mine occurred far more often when slowly accelerating from a dead stop, and often when making a left turn. If you're inclined to try to demonstrate it for them, then that's what you should use in the hopes of simulating it.

Otherwise, tell them to go read NTB13-086, dated September of 2013. That should tell them everything they need to know about the judder.

This is the problem with the dealership here in Calgary Canada, once you signed the purchase order your dead. They even forget who the **** are you. :(

They will tell you talked to our Service department for any problem.

CWA107, what did they replaced on your PF2013?

We had to prove our shudder to the Nissan specialist on our final repair attempt appointment. Before the appointment, we tried to figure out what triggered the shudder in our PF so we would be prepared. We drove our PF for hours in a particularly hilly neighborhood close to our house. We knew that our PF shuddered between 18 and 38 MPH, liked to shudder on left hand turns, in stop and go traffic, and from full stops accelerating up inclines. So, we did all of the above, ALOT. We never could make our PF shudder on demand, but we got where we could tell when our PF was about to shudder, and what conditions to drive it in to increase the odds of a shudder.

I would tell you to do the same - it will significantly increase your odds of making your PF shudder when you need it to for the dealership. Good luck to you, I know it is extremely frustrating.

They've replaced the torque converter, but the jury is still out on whether it permanently fixed the issue, I can say that I haven't experienced it in about 5000 miles now, though it did happen right after they did it.

Hey Noypi I am in Calgary too,
I have a 2014 pf SL, they replace my complete CVT and I have at least 5000 km since no shudder... or at least we haven't feel it as before... Which dealer are you dealing with?, my first did the reprogramming, and after I proved the shuddering they replace my cvt. So reading your comments it looks like my dealer is not as bad as I thought....

I am dealing with Fish Creek.

How did you able to replicate Shudder ?

They did reprogramming long time ago on my PF 2013 SL model.

My question to fellow PF talk member is,

1. How come a 2014 still experience shudder?

2. Nissan Pathfinder is a mass production vehicle, so if your model is produced (e.g. on December 2012) and let say you were able to prove that you are experiencing shudder and Nissan approve to replace your CVT/ Transmission. Isn't it all the PF produced on the same day/month will have the same problem? How can your CVT/TRANSMISSION parts will be different from my CVT if we have the same production date and time?

3. Why not Nissan make a general recall if my 2nd question make sense?

Sorry to say this but this car is not that cheap and for Nissan not to do anything will make everyone of us who own PF 2013 and 2014 will all go down the drain.

Do my questions make sense and comments ??? :)

Many of us want to know why there hasn't been a recall too! I guess because Nissan doesn't have answers yet, or don't have a permanent fix. You can't have a mass recall unless you're prepared to offer a repair.

As to date of manufacture, we only know month and year, at least in the U.S., so you can't use the argument that another vehicle was made at the same time, so needs the same fix.

Hi Jay, you are right only month and year. But how many car they produce in a day and in a month. My point is every parts of the vehicle will be the same for a month produce or maybe not more than a 2 months production. Once you run the production plant your supply must be ready and supplies doesnt mean to last only for a day work. Its not a good planning if your supplies last for one day production only. And normally each parts are produce also by batch so they must be the same quality.

So i still believe, if they come out from the same production month/year and with the amount of people complaining about shudder its not a simple defective one piece of CVT from a batch of supplies of CVT parts.

thats something a lot of people don't get.
i bet even with the defective CVT with them knowing how bad they are, they probably still installed them just to clear shelves and move on.

Very early on, when I was a new member of this forum and first became aware of the jutter issue, I had a theory that the problem might be confined to particular dates of manufacture and was willing to compile a database with a mod's or admin's assistance of the members that had issues.

Since then, there has been an explosion of new members and I think it would be very difficult to cull this information from member's posts unless we started all over again with a new poll. Plus, we even have had members get reprograms or even new transmissions with varying degrees of success, so that should be factored in also.

As long as there were some sort of controls in place to make it a valid survey, I think it would be valuable information for Nissan to know. Perhaps it IS a quality control or inventory sourcing issue as Noipi_Edmund has raised. Who knows?

About 5 days after we took possession of our then brand new 2001 Dodge Grand Caravan ES AWD, a call comes in from the dealer saying not to drive it and that a tow truck will be there the next day for a "recall". Long story short - turns out a very small batch of bolts were used on a few dozen of the zillions of vans they made were not to spec. Only for a very specific time period though. Bolt failure could have caused transmission failure. FOTM is that stuff slips through in sometimes small quantities.

Probably not the case here though... this seems to suggest a systemic issue. But unless you have the data....

One important thing to note is that we don't all agree on what "judder" or "shudder" is... in fact, we can't even agree on a uniform term to describe the phenomenon.

That said, if we can't agree as a forum - just a small subset of the overall owner population - imagine how disparate the problem might be amongst all 2013-2014 Pathfinders. Edmund, your questions/suppositions all assume that the "judder" is a specific problem. I contend that there are a number of different problems that all could be described as "judder" - and that some of them may just be a characteristic of the drivetrain - or may be an issue where the owner just isn't used to the way the CVT works.

So, trying to isolate the problem and make assumptions about where the failure was in manufacturing or quality control is just an exercise in futility. It's also why Nissan seems to have had a hard time isolating and correcting it to the satisfaction of everyone.

Finally, if you read the 13-086 TSB, you can see that there is a flowchart which attempts to classify the specific problem before any repair can be attempted.

In short, the "judder" is a general term that is being used to describe many different problems, likely caused by different components. There is not, nor will there ever be, a "one size fits all" solution - and this likely will go on for several different model years until every kink is worked out.

I agree on CWA 107. In my opinion Nissan should give comfort to all of us like extended warranty or lower the servicing price in case of failure. Coz if Nissan believe in the quality of their CVT then give us something to believe.

Absolutely. They need to publicly acknowledge the problem and then put an extended drivetrain warranty on every vehicle that uses this design. This would do much to inspire consumer confidence and save the resale value of these vehicles.

I wouldn't be surprised, but if you really want to get their attention, make sure you "like" Nissan Pathfinder on Facebook and be sure to pester them in public. That does two things - 1) it airs your concern in a forum where non-acknowledgement looks VERY bad for them and 2) May help deter others purchasing this vehicle (which in turn, gives them incentive to address your concern).

Here, things are relatively contained. Facebook, however, touches a wide audience of potential buyers in exactly the demographic they're chasing with this vehicle.
