Reliability scores look different depending on who is measuring, which is why agreement across several raters carries real weight. These sedans earned top marks from iSeeCars, Consumer Reports and the Power dependability study, covering everything from budget compacts to full-size luxury flagships. Here are eleven sedans that stand out for dependability, with the evidence behind each result.
1. Lexus LS 500: Flagship Without the Flaws
Among luxury large cars, the LS 500 sits at the top of iSeeCars sedan rankings with a 9.3 out of 10 long-term reliability score. That is the highest number any sedan received in the analysis, ahead of far more mainstream nameplates. Lexus pairs a twin-turbo V6 with a hushed, heavily equipped cabin, and the score suggests that complexity has not translated into the failures often seen in rival flagships.
For buyers shopping used large luxury sedans, the rating argues that depreciation here is not a trade for a repair-bill gamble. Condition and service history still matter more than any single score.
2. Toyota Avalon: Big Car, Small Risk
Toyota’s full-size front-drive sedan earns an 8.5 out of 10 in the iSeeCars large car list, the best result among large cars. The Avalon relies on a conventional naturally aspirated V6 or a hybrid setup that Toyota has refined across many models, so there are few unproven parts to wear out.
Used shoppers wanting a quiet highway sedan with room for adults in the back get an unusually low-drama option. The caveat is availability, since Toyota has ended Avalon production and clean examples can command a premium.
3. Subaru Legacy: All-Wheel Drive, Steady Record
The Legacy shares the top midsize score at 7.6 out of 10 in the iSeeCars midsize ranking. Subaru’s standard all-wheel drive adds hardware that many sedans skip, which makes a tie at the head of the class a notable result.
Owners in snowy states can take the score as evidence that traction need not cost dependability. Shoppers should still confirm that a used example has a documented history of CVT fluid service, since that is the component most often raised in owner discussions.
4. Mazda6: The Driver’s Midsize
Mazda’s midsize sedan collects a 7.5 out of 10 in the iSeeCars midsize figures, putting it just behind the leaders in the segment. Mazda leans on conventional six-speed automatics and naturally aspirated four-cylinder engines in many years, an approach that avoids some of the turbocharged and continuously variable designs that complicate rivals.
That makes the Mazda6 a sensible pick for buyers who want sharper handling and a nicer interior without a reliability penalty. The gap to first place is small, so price and condition should decide between it and the Subaru or Toyota alternatives.
5. Subaru Impreza: Entry Price, Top Score
Consumer Reports’ predicted-reliability ranking, summarized by Guide Auto coverage, put the Impreza first among 2026 models at 80 out of 100. The ranking draws on survey responses covering several hundred thousand vehicles, and a compact Subaru topping it beat far pricier competition.
For new-car shoppers on a budget, that means the cheapest way into standard all-wheel drive also carries strong predicted reliability. Predictions are forecasts built on past model years, so a redesigned or heavily updated car can still diverge from them.
6. Toyota Crown: Reborn Nameplate, Strong Showing
Toyota’s revived Crown scores 78 in the 2026 Consumer Reports ranking, a strong result for a model that only recently returned to the lineup. The Crown rides on a mature Toyota platform and standard hybrid powertrain, so much of its hardware has years of real-world use behind it.
Buyers wary of new nameplates can take some comfort from that heritage in the components. It remains a pricier, more distinctive alternative to a Camry, and predicted reliability is no guarantee about any single car.
7. Toyota Corolla: The Default Answer, Still Winning
Corolla scores 76 and ranks fifth among all 2026 models in a Consumer Reports survey of more than 380,000 vehicles, according to Guide Auto reporting. Finishing that high across the whole market, not just among compacts, shows how consistently Toyota’s best-selling small car holds up.
Shoppers wanting inexpensive, unremarkable ownership costs have a proven option here. The trade-off is a plainer driving experience than some compact rivals, which matters less to buyers who value predictability.
8. Lexus IS: Dependability Champion
J.D. Power named the IS the most dependable model overall in its 2026 dependability study, which examines problems reported by owners of three-year-old cars from the 2023 model year. Beating every mass-market and luxury entry makes the compact Lexus sedan the study’s headline result.
Used shoppers eyeing a recent IS can read the finding as a good sign for cars now entering the secondhand market. Because the study covers 2023 models only, it says little about older generations or later redesigns.
9. 2023 Toyota Camry: Award Winner Among Many
A 2023 Camry took a model-level award in the J.D. Power dependability awards, one of eight honors the study handed to Toyota. The study measures problems per hundred vehicles reported by original owners after three years of use.
That record backs the Camry’s reputation as a low-risk family sedan, especially for buyers looking at three-year-old cars. Award categories reward the typical car, so an individual example’s care and maintenance history still deserves a close look.
10. Volkswagen Golf: Hatchback With a Sedan-Level Rating
Volkswagen’s Golf rates 7.6 out of 10 among used small cars under $20,000 in the iSeeCars budget rankings. That is a respectable figure for a European compact with turbocharged engines, a type of car often assumed to be costlier to keep running.
Bargain hunters wanting a more refined cabin than most cheap compacts have a credible candidate. The score applies to a price-capped used group, so individual cars with missed maintenance can still turn expensive.
11. Nissan Maxima: Old-School Large Sedan
Nissan’s Maxima leads used large cars under $20,000 with a 7.3 out of 10 in the iSeeCars used-car list. Its front-drive V6 formula has been in production for decades, giving the platform a long record of refinement.
Buyers wanting a roomy, quick sedan on a modest budget get a reliable choice, though a 7.3 trails the best scores in this lineup. Early continuously variable transmissions in some model years deserve a pre-purchase inspection.
