2003-2010 Nissan CVT Warranty Extension
In 2010, Nissan USA was forced to extend the warranty on the CVT to 120,000 miles (up from the factory 60,000-mile powertrain warranty) for virtually all Nissan models from 2003-2010 which used CVTs. This included the 2007-2010 Altima, Maxima, Versa, and Sentra; the 2008-2010 Rogue; and the 2003-2010 Murano.
When the CVT in my 2013 Altima failed at under 100k miles, I spoke with Nissan Consumer Affairs several times to lay out the case for why the CVT should be warrantied to 120,000 miles on newer model years. Just to check, I asked the Regional Specialist whether the 2003-2010 warranty extension was offered specifically because of widespread problems with the CVTs in those model years.
The Nissan USA Regional Specialist confirmed that the warranty extension in 2010 was, in fact, a response to widespread problems with earlier-generation CVTs.
Thus, if a high failure rate was sufficient reason to extend the warranty on older Nissan CVTs, then the evidence presented throughout this site (illustrating a high failure rate for newer Nissan CVTs) indicates that a similar warranty extension should be made for the newer vehicles.
Recalls and TSBs
2013 Altima TCM Recall
The following letter was mailed to owners of the 2013 Altima in the USA:
To summarize this recall, the transmission control module (TCM) -- the computer which controls the CVT -- needed to be reprogrammed at a Nissan dealership. The letter advised owners that the reprogramming should be done quickly to avoid potential "damage to your vehicle's transmission."
Personally, I received this letter in early 2017, at which time my Altima had over 50,000 miles on it. Thus, it's reasonable to assume the faulty TCM programming which needed to be remedied had been adversely affecting my CVT for the first 50,000 miles of the car's lifespan.
It appears Nissan acknowledges a critical flaw in the CVT system (this includes the TCM) and was compelled to start a service campaign intended to mitigate new CVT damage going forward, but refuses to take responsibility for damage incurred during the first 3-4 years of buyers' ownership.
