CVT vs automatic transmission: which draws more owner complaints?

We matched 782 model years to the transmission the EPA lists for them. CVTs were worse before 2014 and better since 2018. The data, brand by brand.

By Eyal Malka · November 5, 2026 · Data: NHTSA, updated October 3, 2026 · How we score

"Avoid CVTs" is one of the most repeated pieces of used-car advice there is. It is also one of the easiest to test, because two public government datasets, put side by side, answer it: the EPA's fuel-economy listings say which transmission each car was sold with, and NHTSA's owner-complaint database says what owners of that car complained about.

We did that for every mainstream car, crossover and minivan we track. The short answer is that the advice was right about the early 2010s and is out of date now. The longer answer is that the transmission type matters far less than the brand and the model year, which is the thing a buyer can actually check.

How we sorted the cars

The EPA's database at fueleconomy.gov lists every engine and transmission combination certified for each model year. A continuously variable transmission shows up as "Auto (variable gear ratios)" or "Auto (AV)"; a dual-clutch or automated manual as "Auto (AM)"; a conventional automatic as "Auto 6-spd", "Auto (S8)" and so on. For each model year we put the car in one of four groups:

• CVT: every automatic version of that model year was a CVT.
• Geared automatic: every automatic version was a conventional stepped automatic.
• Dual-clutch: every automatic version was a dual-clutch or automated manual.
• Mixed: the model year was sold with more than one kind, so its complaints cannot be pinned on one. These are left out of the comparison.

Manual versions are ignored, because NHTSA files their complaints under the same model name and they are a small share of sales. Full hybrids that use a planetary power-split gearbox (the Prius, Insight, Niro and the later hybrid-only Venza and Sienna) are left out, because the EPA lists them as variable-ratio but they have no belt or chain to wear.

The measure is the one used everywhere on this site: the drivetrain share, the fraction of a model year's NHTSA complaints that concern the engine, the transmission or the fuel and propulsion system. Only model years with at least 100 complaints are counted, which leaves 782 model years in the four groups. How to read these numbers. The script that produces every figure on this page is tools/guide-stats.mjs in our repository, run against the same cached data as the car pages.

One caution before the numbers. The drivetrain share counts engine complaints as well as transmission complaints, because owners and NHTSA's categories do not separate them cleanly. A car with a geared automatic and a failing engine scores high too. That matters below.

The headline comparison

Taken as a whole, the CVT model years have a lower median drivetrain share than the geared ones. That is not the result the folklore predicts, and it should not be read as "CVTs are more reliable" either, for the reason in the caution above: the geared group carries most of the engine-heavy model years of the decade. The Kia models we track that used a geared automatic, for example, have a median of 59% across 49 model years, and in 47 of those 49 the Engine category outnumbers Power Train, NHTSA's bucket for the transmission.

What the table does say is that "it has a CVT" is not, on its own, the warning sign it is often made out to be. The dual-clutch line is a different story, but ten model years, seven of them Ford Fiesta, is not enough to generalise from.

The era is what moves the number

Split the same model years by when they were built and the picture changes completely.

In the early 2010s the advice was right. Twenty-three of the 27 CVT model years from 2010 to 2013 with enough complaints to score are at 40% or more, against fewer than half of the geared cars of the same years. By the 2018 model year the position has reversed: only 12 of 58 CVT model years score high, and the median falls to 22%, about half the geared figure.

So if you are buying a car from the early 2010s, a CVT is a genuine reason to look harder. If you are buying one from 2018 onwards, it is not, by itself.

Brand by brand

The cleanest comparisons are within one manufacturer, where the same company built both kinds or built only CVTs for long enough to see a trend.

Nissan

Nissan sold CVTs in almost everything, so there is nothing to compare against inside the brand, only years. Across 55 CVT model years the median is 43%, and 34 of them score high. The bad years come in a block: the Sentra is between 61% and 73% every year from 2012 to 2017; the Rogue is 58% to 76% from 2010 to 2014; the Altima peaks at 65% in 2016. Then the block ends. The 2018 Altima is 21%, the 2018 Rogue 17%, the 2020 Sentra 8%.

The exception is the 2022 and 2023 Rogue, which climb back to 79% and 67%. Those years changed the engine as well; the turbo engine guide has that side of it. A recent Nissan is not automatically a safe Nissan.

Subaru

Subaru is the strongest case against the blanket rule. Its 36 CVT model years have a median of 20%, the lowest of any brand here, and only 4 score high: the 2012 to 2014 Impreza and the 2015 Forester. From 2016 on, no Subaru CVT model year we track scores high. The 2019 Outback is 7% on 1,034 complaints.

Honda

Honda is the cleanest within-brand comparison, because it sold both kinds across the same decade. Its 25 CVT model years have a median of 25%, and 6 score high; its 46 geared model years have a median of 35%, and 14 score high. The weak CVT years are early: the 2015 to 2017 CR-V at 48% to 56% and the first two years of the HR-V. From 2020 on, every Honda CVT model year we track is at 30% or below, and the 2022 Civic is 3% on 959 complaints.

Toyota

Toyota runs the other way, which is why "Toyota is safe" is as weak a rule as "CVTs are bad". Its 52 geared model years have a median of 25%. Its 8 CVT model years, nearly all Corolla and C-HR from 2018 on, have a median of 58%, and 7 of the 8 score high. The samples are moderate, a few hundred complaints a year, but they are consistent from year to year.

Jeep

The Patriot and Compass years that were CVT-only in the EPA listings are all high, a median of 53% across 6 model years. But the geared Jeep model years have a median of 49% across 44, so a Jeep buyer who avoids the CVT has not avoided much.

Why the folklore stuck

The early CVT years were genuinely bad, and the bad ones were concentrated in a few very familiar nameplates, the Nissan Sentra, Rogue and Altima above all, so the problem had an obvious name. The geared automatics with bad records in the same years were spread across more brands, and many of their complaints were about the engine rather than the transmission, so they never attached to a single label in the same way.

The data also explains why the advice now does harm. A buyer who rules out every CVT on principle rules out the 2019 Outback and the 2022 Civic, two of the cleanest model years in their classes, and may end up in a geared car from a model year with a worse record.

What to do with this

1. Check the model year, not the transmission type. The difference between two years of the same car is routinely bigger than the difference between a CVT and a geared automatic. The free report shows the year you are looking at and the years either side.
2. Treat a 2010 to 2014 CVT as a reason for extra care. That is where the data supports the reputation. Ask for the transmission service history, and test-drive for the symptoms in the transmission check guide.
3. Do not treat a geared automatic as a clean bill of health. More than half of the geared model years in this comparison score high.
4. Check open recalls by VIN. A recall or software update on the transmission changes what the history means. How to check a VIN for open recalls.
5. Know which one you are looking at. Sellers do not always know. The EPA's listing for the year, make and model at fueleconomy.gov will tell you which transmissions it was sold with, and the window sticker or the dealer can confirm which one this car has.

Frequently asked questions

Are CVT transmissions less reliable than regular automatics?

Not as a rule. Across 782 model years we matched to EPA transmission listings, CVT-only model years had a median drivetrain complaint share of 36% against 44% for geared automatics. CVTs from 2010 to 2013 did much worse than geared cars of the same years; CVTs from 2018 onward did much better.

Which brands have the fewest CVT complaints?

Among the brands with enough CVT model years to compare, Subaru has the lowest median drivetrain share at 20%, followed by Honda at 25%. Nissan is at 43% and Toyota's newer CVT models at 58%, though Nissan's recent years are mostly much lower than its early ones.

Should I avoid a used car with a CVT?

Avoid specific model years, not the transmission type. A 2013 Nissan Sentra and a 2019 Subaru Outback both have CVTs and sit at opposite ends of the complaint data. Check the year by VIN before deciding.

How do I know if a car has a CVT?

The EPA's listing for the year, make and model at fueleconomy.gov names the transmission for each version: "variable gear ratios" or "AV" means a CVT. The original window sticker or the manufacturer's spec sheet will say the same for the exact car.
