Why Nissan CVTs FAIL

Here’s an in-depth look inside a continuously variable transmission, how it works and what some of the common causes of failures are.
The continuously variable transmission made it to the mainstream thanks to Nissan’s push for CVT’s in its front wheel drive vehicles 18 years ago with the Nissan Murano. CVT’s employ the use of a steel belt with adjustable pulleys to achieve various drive ratios. Since the pulleys do not have steps or stages like a traditional automatic, manual or dual clutch transmission, it can continuously shift input / output ratios without abrupting power flow.
Nissan’s CVT’s have been the topic of many due to its extremely high failure rate. In this video, a continuously variable transmission from a 2006 Nissan Murano is taken apart, torn down and dissected to see how individual components are like and how they function as part of the transmission. We also discuss failure modes, advantages and disadvantages of Nissan’s CVT’s what you should do if you own a vehicle with one.

A strong burnt smell this was it. No engine indicators ever came up on for bad transmission etc. My concern is what if I didn’t change the fluid? Could the fluid have still lasted or would the fluid have caused serious problems and burned the surroundings of the steel belt??? I knew there is no exact answer or way of knowing. I really wonder how much more time of that burnt fluid especially with that strong pungent burnt smell could or would have damaged inside the CVT and what would the old burnt fluid damage specifically??

Meaning belt isn’t the failure point. From my understanding w 190k mi on CVT and on the clock keep going. From 2011 2.5 Altima. Most failures come from lack of maintenance (every 25k to 35k fluid change), or excess heat(can be addressed with external cooler. Which also extends oil life about 10k more) and I’m driving this car under extreme condition. Just so you know. 120f AZ heat wouldn’t be any good for this tranny but yet it drives like a sewing machine and makes me smile whenever I get to the gas station. Just don’t forget that CVT suffers from extreme heat. And there are ways to make it run right. Before rebuilt is actually needed. Plus these can take some damages compared to automatic transmission where everything is actually gear. And run by hydraulics where kick down can actually cause more harm for the tranny than it should be.

What i have witnessed working for Nissan several years ago was sales people telling buyers "Oh its a sealed transmission, no maintenance at all" thats a lie out their ass and it infuriated me. Thats why majority of CVTs fail, not the proper maintenance.

[@fun_ghoul]

Salespeople are like others, they act in their own interest. If more vehicles fail, that's more potential sales for them down the road.

[@prototype_0xD1]

Exactly this. I even had a service writer at a Nissan Dealer tell me that I didn't need to change my fluid at 40k. It just needed an inspection. I told him there is no such thing as lifetime fluid and made them do it. Fluid went from dark/dirty green to bright green. I, however, turned down their stupid 40$ cabin air filter they were pushing.

I just replaced my stepper motor, and the car drives a little better but it still shows the same code after a couple resets, do you have any clue why that might be? It drives way better but it still slips but I can feel it “shifting” up but it takes some time. The transmission is at 172k

[@Ashquacks]

@@air-headedaviator1805 well, if you repair things for a living (I do), you get the idea what fails most frequently, and what is the cause of failure. After some time, the patterns develop. When you are describing patterns from your memory only, your opinion is not worth much. In order to get your personal bias and your memory problems out of the equation, you need to back up your opinion with hard data (like the computer entries about failures in the last 5 years for a particular car model). Once you have done it, your opinion becomes a reliable source of information.... I'm pretty confident that this guy knows what he is talking about, and he most likely looked at hard data in forming his opinions...

Thank you for this post. I have a 2013 Jeep Compass with the 2.4. I think this is the CVT that is in my car. Also, a few Nissan (of course) and some models of Subaru. My CVT started going bad at about 25K. I took it back to the Jeep dealership multiple times as it was still under warranty, and of course, they could find absolutely nothing wrong with my car. Then, when my Compass went out of warranty, miraculously, they discovered I needed a new CVT. I have been a Jeep owner since 1983. CVT or not, I WILL NEVER BUY ANOTHER JEEP AGAIN.

I know better than to buy any vehicle with a CVT. BTW, the Compass is not a true Jeep. It is a Fiat. Stick with the Grand Cherokee, Cherokee, Wrangler and the new Wagoneer.

Good decision, ALL new Jeeps are garbage. Anyone who says otheriwse doesn't work on them. Anything and everything produced by FCA is trash, and Chrysler was already ruining the Jeep brand before Fiat came along and made everything worse. Jeep hasn't made a vehicle worthy of purchasing since they killed the 4.0 inline 6 and even before they killed it, they made it less reliable each year by using cheaper innards.

Hers has 67K miles and it needed tires, brakes, a battery and wiper blades. Other than oil changes, these vehicles needed no other attention. They look and run like new and right now, there is no reason to trade them in. These are the two best vehicles I have ever owned. And to put this into perspective, the first new car I bought was a 1973 Ford LTD Brougham. I have owned quite a few vehicles in the past 50 years.

Not the most reliable transmission I have had two of these fail at around 70000miles with the same fault, the plastic spider that retains the solenoid valves to the valve block fails ( it is the wiring loom to the solenoids and the plug to the loom out side the box) it is internally wired in aluminium which fatigues and breaks contact.
