Technical Service Bulletin 16-053 for CVT---Accord & CR-V 2015-2016
Honda issued Technical Service Bulleting 16-053 on August 3, 2016. It applies to 2015-16 Accord (L4 with CVT) and 2015-16 CR-V (ALL with CVT).
Background: "An incorrect learning value in the PCM may cause a pressure problem in the CVT under certain driving conditions, causing a surge in RPM because the CVT belt slips at highway speeds and eventually setting DTC P1890 (CVT speed control system)."
Customer Notification: "Owners of affected vehicles will be sent a notification of this campaign. Do an iN VIN status inquiry to make sure the vehicle is shown as eligible. Some vehicles affected by this campaign may be in your used vehicle inventory. Repair these vehicles before they are sold."
Corrective Action: "Do the inspection and depending on if DTC P1890 is set or not, update the PGM-FI software or replace the transmission and update the PGM-FI software."
In other words, if your dealer service department finds an error code, they need to replace the transmission. If they do not find an error code, then they need to update the software.
I have not gotten any letter from American Honda yet, but I called them and gave them the VIN of my 2016 CR-V. They told me I was affected by this TSB. I brought my vehicle to Honda service this past Saturday, and they did the update. I did not need any letter for them to do the update.
Even if you're not getting a surge in the RPM at the moment, I'm thinking that it would be a good idea to go in and get the update anyway. I am attaching a .PDF of the bulletin.

My suggestion would be to tell the dealer that you're aware of a Technical Service Bulletin (#16-053) for the CVT, and you want it taken care of. Honda is notifying owners of the TSB, but my understanding is you don't need to wait for a letter in order to get the update. (I had the update done without having the letter.) The dealer may or may not be able to do the update when you buy the vehicle, but if not, that's OK, unless you're concerned about whether or not there is an error code that would require the CVT to be replaced. Also, there is a possibility that the dealer already applied the software update to the vehicle, but I'm willing to bet that isn't the case.
For what it's worth, the dealer who updated my vehicle told me that he already had lots of vehicles come in for the TSB, and not a single one had the error code and needed a replacement transmission; every one of them only needed a software update. So that's encouraging.
In any event, I wouldn't hesitate buying the vehicle you want. You do have the option of telling the dealer that you won't sign the papers until they check for an error code and do the software update. That's up to you. But then be prepared for having to wait for however long it will take to get your vehicle into the service department; hours, days, who knows. The update itself doesn't take long. The real trick is just getting it into the service department. Personally, I would sign the papers, take the vehicle, and just make an appointment to have the update done, if they can't do it right then and there. Just keep in mind the remote possibility that they would have to replace the transmission. But my guess is that's a longshot.
