What the bulletin says

CAMPAIGN BULLETIN CVT Warranty Extension In an effort to assure customer satisfaction, demonstrate our confidence in continuously variable transmissions (CVTs), and to address customer concerns including those expressed by customers in a class action, Nissan will extend the warranty coverage on the CVT. The warranty extension includes the CVT assembly and internal CVT components, gaskets, and seals, CVT control valve body, torque converter, cooler kit (if applicable), Automatic Transmission Control Unit (ATCU) and reprogramming of the Transmission Control Module (TCM), on the vehicles listed in this announcement. The warranty is being extended from its original duration of 60 months/60,000 miles to 84 months/84,000 miles (whichever occurs first). Coverage of other vehicle components remains unchanged, and all other terms, conditions, limitations and exclusions of Nissan’s New Vehicle Limited Warranty continue to apply. ***** What Dealers Should Do ***** 1. If an owner contacts a dealer with a CVT concern in an owned or leased vehicle, verify warranty coverage for the specific VIN and then inform the customer of any diagnostic charges. NOTE: Some owners may have opted out of the warranty extension by excluding themselves from the class action settlement, thus it is important to check the VIN for each vehicle to verify coverage. 2. Use the appropriate Technical Service Bulletin (TSB) and/or Electronic Service Manual (ESM) to diagnose the root cause of the customer concern and identify the correct repair to resolve the customer concerns. NOTE: Dealers will need to follow the warranty process and obtain pre-approval using the VCAT tool. Please reference WBI/21-002. Control valves and CVT belt and pulley kits do not require pre-authorization for repairs made under warranty if they are within the dealer’s DCAL limit. 3. CVT warranty coverage can be confirmed using the warranty extensions/customer service initiatives page in Service Comm or DBS National Service History. 4. If the vehicle is no longer covered by a powertrain or parts warranty, provide owners a repair estimate for a test drive, diagnosis, and repair. If an owner requests assistance, be sure to consult goodwill guidelines available in the Assurance Products Resources Manual (APRM) section 2.2 and obtain the necessary approvals before proceeding.

What owners reported
Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 614 complaints with NHTSA since 2015. 74 of them name Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2016 Nissan Maxima, the 14 owners who gave an odometer reading for Power Train reported it at a median of 74,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
After numerous visits to the Nissan dealership without getting answers and clearly explaining that my car is experiencing CVT judder and vibrations. I have been experiencing the vibrations as told to Nissan for awhile but I don't think they wanted to replace my CVT transmission since it was still under warranty so I was told the noise…

When making sharp turn (left or right) into fast moving traffic and driving straight after the turn, while pushing accelerator pedal hard, the RPM will go up high but the speed will not (it will increase very slowly).

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Nissan CVT a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the CVT repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does CVT cover?
The manufacturer filed it against 6 model years: 2018 Nissan Maxima, 2017 Nissan Maxima, 2016 Nissan Maxima, 2018 Nissan Murano, 2017 Nissan Murano, 2016 Nissan Murano. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
