New to forum posting about 2015 Altima S 4cyl failed CVT experience. Also have a 2013 Frontier with no problems at all. Altima is wife's car.
Fixed free by dealer at 78K. Started having problems about 5K earlier but got much worse in last few weeks. Slipping, slight burnt smell, several times no change when pushing gas pedal, sometimes high revs but no trans response. Some rumbling/vibration at highway speed. No limp mode. Most symptoms after warming up. Had received Nissan letter extending warranty to 84K. Have been taking both vehicles to same dealer and they have always been nice and fair. They found P17F0 code (which he said always calls for a repair) stored in TCM and said this service bulletin applies:
https://static.nhtsa.gov/odi/tsbs/2016/MC-10119277-9999.pdf. Said Nissan requires several hoops to jump through before authorizing repair, including video, pan removal etc. Took 2 1/2 days to fix. Repair bill said R&I (remove and install, I assume) CVT transaxle assembly and R&I CVT sub assembly. Parts list included valve assembly kit, belt-pulley kit, cooler flush stuff, and lots of nuts, clips, pins, o-rings, gaskets and clamps. So they did the rebuild themselves reusing my case, not swapping in a whole new rebuilt one as he first said they might.
I asked how many failed CVTs they have had and he said a number of them but not that many Altimas. More Versa Sentra and Rogues. He also said there is no such thing as installing a new transmission, that everything is rebuilt, that they don't keep making new transmissions for older cars. This was to say I shouldn't feel slighted or cheated out of a new transmission.
I'm happy it was straight forward with no hesitation or hassle on their part, but not happy with the fact that I only got 78K out of a new car trans (I'm original owner). I had fluid changed at 36K. I asked if this means I'm still in the 84K extended warranty program and if this one fails within the 6K that remains they will fix it again but after that I'm on my own. He said no it's more because this repair comes with a 12 month / 12K warranty regardless. I felt a little better but not much. That's just 2 or 3 oil changes. I said if I now have the same trans I had when new, I could only get 78K more before it fails, but the warranty will be long over. He said well, yeah I guess so. He did say they installed upgraded parts, beefier and better, because the car is 5 years old and they are always improving stuff. I'm thinking about getting rid of it while it's running well. Other than this trans problem we really like the car. Even though it's paid for the blue book price is very bad, in my opinion. My '13 Frontier is 2 years older but over double the value. So getting rid of it will mean a lot more out of pocket for some other make. Have had a Camry and an Accord with zero problems.
