Nissan Sentra CVT Failure

**Top_Fuel** · 05-06-2019, 08:00 PM

A co-worker has a 2015 Nissan Sentra with a CVT. I think it has about 70,000 miles on it. After some ongoing symptoms (jerky, RPMS erratic, trouble climbing a hill) the dealer can finally duplicate these problems and they have called in for a replacement transmission from Nissan. Unfortunately it's on a national back order right now...so he's not sure when the new trans will actually be ready. It's a Jatco unit...but I'm not sure of the model. Nissan has had a LOT of issues with CVTs and there are class action lawsuits flying all over the place.

I had a co worker with a 14(?) rogue with around 140k kms iirc, complaining about transmission problems. He took it to the dealer to get their opinion. They replaced the valve body and when that didn't fix it they replaced the entire cvt. Thankfully for him he unknowingly purchased extended warranty when they bought it new.

That's funny...this guy also purchased an extended warranty. But it wasn't from Nissan. The Nissan dealer actually sold him a third-party warranty on a new car. How cheesy is that?!? This guy should have know better. This warranty company was actually close to denying his new transmission because he couldn't prove that he had done all his engine oil changes on time?!?

After a little bit of fighting they came around.

Yeah, the gf bought 3rd party warranty for her optima new from the dealer. Seems like a joke but might come in handy. But yeah, gotta keep all receipts for everything. Thankfully she gets free oil changes from the selling dealer but we moved in the fall across the city so now it's 30 min one way to get a free oil change. Almost not worth it but should have less hassle in case of a claim. They keep trying to make her pay for checkups/inspections as per service schedule: inspect belt,inspect cv boots,inspect brake hoses and fluid,tire rotation etc...

Sentra uses the same CVT7 as our Mirage correct? I know its used on the Cube and Juke. Is there any reason why Nissan is doing so badly in reliabilty vs Mitsu, using the same Jatco product? Ive heard the low curb weight, low torque theories but is there a massive difference in programming ECU work?

Same CVT, huge differences in programming. Nissan and Daewoo (Chevy Spark) programmed their CVT's differently with not so good results.

Its crazy to think the same product can be so different in makes and models. I wonder what Mitsu engineers figured out what Nissan/Chevy couldnt?

Just got an update on this. The Nissan dealer is saying that there are more than 1100 CVTs on national backorder right now. The dealer working on his car is waiting on 5 of them! Apparently Jatco is cranking them out as fast as they can. It will be interesting to see if they install a new or remanufactured CVT in his car.

Sad Nissan is more French than Japanese now, explains alot in terms of product reliability. I wish Mitsubishi had the money to go back to being independent.
