CVT Transmission Problems: It Depends Whose CVT

The common view treats the CVT itself as the fault, and any car with a CVT as a car to avoid. Two records anybody can check, NHTSA's complaints and the published class-action settlement terms, don't support that.

Both support something narrower and more useful if you own one of these cars or are about to buy one. They point at whose CVT it is rather than at the technology.

What are the signs of a failing CVT?

The early signs of CVT failure are flaring revs, shudder, whine and a slow take-up. The usual list of bad-transmission signs, harsh or delayed shifts and gears hunting, describes a conventional automatic, so a CVT checked against it looks fine until something expensive happens.

The one to treat as urgent is limp mode. At highway speed it means the car has cut power, often to protect the transmission, and a car that suddenly stops accelerating in traffic is a safety problem before it is a repair bill.

Before assuming the worst, have the fluid level and condition checked, because a low level produces slipping that reads exactly like a failing unit. Our guides to checking transmission fluid and to checking it without a dipstick cover both cases, and many of these cars are sealed.

What the fluid looks like is a weaker signal than most people think, and our page on what fluid color actually tells you explains why. If the level is dropping rather than merely dark, transmission fluid leak repair costs covers that bill.

Which cars have the most CVT transmission problems?

Four Nissan models stand apart, the Sentra, Versa, Altima and Rogue, in that order, in NHTSA's record of owner complaints, which are unverified. The weakest of those four, the Rogue at 7.1%, is still more than double the highest non-Nissan share on the list.

The table counts complaints that mention the CVT by name for nine cars with a CVT and four with a conventional automatic, 2014–2018 models. Cars without a CVT barely register, 6 mentions in 9,578 complaints, so the count is measuring the transmission.

Above them, the spread among cars that do have a CVT is enormous. Honda Accord sits at 0.7% and Subaru Outback at 1.3%, closer to the no-CVT cars than to the top of the table, while Nissan Sentra sits at 15.1%.

That's the finding, and it's narrower than the usual verdict on CVTs. Belts and pulleys aren't a doomed idea: Subaru has been building CVTs at volume for as long as anyone, and the Outback's CVT share is nearer to a Camry's than to a Sentra's.

What owners write is worth knowing before a test drive, because it's the distinction a driver can make and a stored code often can't. The words they reach for are shudder, jerk and slip rather than anything about a gear.

This table of CVT transmission problems can't tell you two things, and both are limits of counting complaints:

• The counts aren't adjusted for sales. A model that sold in big numbers has more chances to generate complaints than one that didn't, and nothing in the raw count corrects for it.
• People who file are self-selected. Nobody fills in a federal complaint form because the car is fine, so the pool is drawn from owners who already had trouble.

Each figure is a share of that car's own complaints, which isn't the same as how many of them fail. A car with few other complaints shows a higher share.

What Nissan agreed to pay for

Nissan agreed to extended CVT cover in class-action settlements, set out by car below. They run through federal courts, they're administered publicly, and their terms are published.

All four models at the top of the complaint table are covered, and the Infiniti QX60 has a longer term. A later settlement reaches the Murano and Maxima, and the 2015–2018 Pathfinder sits beside the Rogue at 84 months or 84,000 miles, though the table didn't count those.

So the complaint forms owners file and the settlements the courts approved point at the same four cars. Most of these terms have now run out, though a late-2019 Sentra or Versa may still be inside its term, so check your car's in-service date first.

Nissan isn't alone. Subaru extended the CVT to 10 years or 100,000 miles on certain 2010–2020 models, in several programs, and Honda to 7 years or 150,000 miles on the 2016–2020 HR-V, and some of that cover is still running, so have a dealer check the VIN.

What a settlement does and doesn't prove

Nissan settled without admitting liability. A settlement is an agreement to stop arguing, not a court finding that a component was defective.

What it does show is a manufacturer choosing to extend warranty cover on one component across the Sentra, Versa, Altima, Rogue and QX60. It also reimbursed repairs owners had already paid for, including work done at shops that weren't its own.

The absence of a settlement elsewhere proves less than it appears to. Class actions follow large fleets and deep pockets.

Why there was never a recall

Recalls address safety defects, and a transmission that wears out early is a warranty matter. It gets settled through warranty extensions and lawsuits, which is precisely what happened here.

Across the four 2014–2018 Nissans at the top of the table, one recall touches the transmission, for gear position indication, not CVT durability. Nissan's 2016 campaign PC490, not a recall, reprogrammed the CVT on about 1.7 million 2013–2016 Altima and 2014–2016 Rogue cars for belt slip.

No recall doesn't mean no problem. It means no recall was filed for CVT durability, and a great many expensive faults never become one.

Owning or buying a car with a CVT

If you own one of the covered Nissans, find out whether your vehicle falls inside a settlement's model years. On a Subaru or an HR-V, check whether one of those programs applies.

Each term runs from the original in-service date, the day the car was first delivered new, rather than from when you bought it, and most of Nissan's have run out, so check that date first. Our free VIN decoder confirms the model year and lists its recalls before you pay for a repair, and NHTSA's VIN search shows which are still open.

What a replacement costs is the question behind all of this, and our own page prices a rebuilt or replaced transmission. The reimbursement cap in the settlement table is the reason to check your cover first.

If you're buying used, this is a service-history question, not a brand question. A Sentra with documented transmission work is a different proposition from one with none, and the table above is a reason to ask rather than a reason to walk away.

If your CVT sits nearer the bottom of that table, the complaint record doesn't support treating it as a liability. Use the fluid your manual names: Nissan's 2014 Altima manual allows only Genuine NISSAN CVT Fluid NS-3 and says other fluids damage the CVT, outside the warranty.

A machine flush is a different proposition from a drain and fill, and worth reading before agreeing to one: is a transmission flush necessary. For the symptoms that aren't CVT-specific, and what each possible cause costs, see the signs a transmission is going out.

What a CVT actually is

A continuously variable transmission has no fixed gears: it runs a steel belt or chain between two pulleys that change diameter, so the ratio slides smoothly across its whole range instead of stepping through six or eight fixed points. A conventional automatic has a fixed set of gears and picks between them.

The engineering reason is fuel economy. An engine has one narrow band where it is most efficient, and a CVT can hold it there while road speed changes underneath, which is why they spread quickly through economy cars and compact crossovers rather than through sports cars.

It also explains why a failing CVT doesn't feel like a failing automatic. Wear arrives as noise, shudder and slipping instead of as harsh or delayed gear changes.

The belt a CVT actually runs on

The 2013 Altima and why its fall isn't a fix

One more caution, from outside the table's years: the 2013 Altima carries 2,307 complaints, 505 of them against the power train, the largest single model year in this data and the root of that car's reputation. The 2018 Altima carries 224, with 23 against the power train.

It would be easy to read that fall as Nissan fixing the problem, but two things argue against it. A 2013 car has had thirteen years to accumulate filings and a 2018 car has had eight, so part of that fall is nothing but age.

The years in between don't drop in a straight line either: the power-train count falls to 161 by 2015, climbs back to 235 in 2016, then falls again. That isn't the clean drop a fix would leave.

Common questions

Asked most often

Are CVT transmissions unreliable?

The complaint record doesn't support that as a blanket statement, because several manufacturers' CVTs sit close to cars with conventional automatics. The spread between brands is far larger than the gap between the two technologies.

Which Nissan CVTs get the most complaints?

Across 2014–2018 model years, Nissan Sentra, Versa, Altima and Rogue occupy the top four positions, with the Sentra highest at 15.1% of its complaints naming the CVT. Those four are also the models covered by class-action settlements.

Did Nissan admit its CVTs were defective?

No, the settlements were reached without any admission of liability. What Nissan agreed to was extending transmission warranty cover and reimbursing certain repairs.

How long should a CVT last?

It depends on the car and how it's serviced. Nissan extended cover to 84 months or 84,000 miles on the affected cars, but that's a warranty term, not a life.

Is a shudder always the transmission?

No, so have the fluid level checked first, since a low level causes slipping and shudder that reads like internal damage. On a CVT, a shudder at constant speed is more suggestive than one during acceleration, because there's no shift happening.
