Eight of the top ten most reliable brands are from Asia, and only  one--Buick--is a domestic, according to the latest Annual Auto  Reliability data from Consumer Reports (CR), the nonprofit research,  testing, and consumer advocacy organization. But there were some  positive indicators for the domestics, too, as American models topped  seven vehicle categories--an unusually strong showing. 
The 2021 Auto Reliability  Report is based on data collected from CR members about their  experiences with more than 300,000 vehicles in the annual surveys. The  survey findings were announced at an online news conference before the  Detroit-based Automotive Press Association today. Owners reported  everything from transmissions needing replacement after as little as  5,000 miles to display screens that required hardware replacement and  misaligned tailgates and doors.
 "With new-car prices at all-time highs and a shortage of vehicles on  dealers’ lots, it’s more important than ever to consider reliability  when you invest in something new,” said Jake Fisher, senior director of  auto testing at Consumer Reports. “Buying a reliable vehicle can help  ensure that you’ll be able to hit the road when you need to, and not  worry about getting stuck waiting on parts for repairs.”
 Other highlights from CR’s influential annual report include the following:
 - Despite their complexity, hybrids and plug-in vehicles are among the most reliable models.
- High-end electric-powered Sport Utility Vehicles are among the least  reliable vehicles, but NOT because of their relatively simple  powertrains. Complex electronics are their Achilles Heel, at least for  now.
- Some Hyundai, Kia, Subaru, and Toyota models continue to have  problems due to technologically advanced, and complex, transmissions.
CR’s auto statisticians calculate reliability ratings for every major  mainstream car, minivan, SUV, and truck on the market, even ones that  are brand-new and redesigned for 2021. To do so, the team analyzes  annual CR member surveys data on a model’s reliability history,  calculating the brand’s overall reliability and, if applicable, the  reliability of models that use some of the same components.
Consumer Reports’ analysis of new-car reliability is a key element of  CR’s Overall Score, which is a holistic measure of a vehicle’s quality  designed to make it easy for consumers to quickly find the best cars,  SUVs, and trucks to suit their needs. The Overall Score also includes  road-test performance, owner satisfaction survey results, whether a  vehicle comes with key active safety systems, and results from crash  tests, if applicable.
 “The pandemic is creating a scramble for consumers as they face a  reduced supply of new cars and significantly higher prices. That's why  it's more important than ever that people get trusted help finding safe,  secure, and reliable vehicles,” said Marta Tellado, President and CEO  of Consumer Reports. “Our annual reliability reports, combined with our  comprehensive auto testing, can empower consumers with the trusted  information to make better purchases and navigate this unusually  difficult marketplace.”
 Eight of the 10 Top Brands are from Asia
 Of the top ten most reliable automakers, eight are headquartered in  Asia, with Lexus, Mazda, and Toyota in the top three spots respectively.  Historically, Lexus and Toyota have regularly been at the top of CR’s  brand rankings for reliability. That’s an especially noteworthy  accomplishment for Toyota, which has a wide array of different  nameplates in the survey--13 in all. Mazda, which was the top brand  overall last year, falls to second place. Mazda’s above average overall  performance was marred by the Mazda3 small car, which has average  predicted reliability due to problems with its climate system and in-car  electronics issues. Mazda has a conservative design approach with  shared platforms and similar components, which helps it to produce  reliable vehicles overall. Mazda has also stuck with its dependable  six-speed automatic transmission while other automakers use more complex  ones with eight or nine ratios or continuously variable transmissions,  some of which have proven troublesome.
 All Lexus models score average or better for reliability in CR’s  report. The Lexus GX SUV is the most reliable new vehicle overall this  year; owners reported no problems for the three model years that CR  analyzed in the brand rankings. The UX is Lexus' only average model.
 Third-ranking Toyota has only one model scoring below average, the  Corolla Hatchback; CR’s members reported issues that required a  transmission replacement or rebuild. The RAV4 remains average mostly  because of problems filling the fuel tank on some versions. The Tacoma  and the redesigned-for-2021 Sienna are both also average; the Sienna  showed some power equipment problems. Both the RAV4 Prime and Venza, new  for 2021, are well above average.
 Infiniti ranks fourth overall, an admirable improvement of six spots  this year. The Q50 sedan remains impressive and the troublesome QX50 SUV  improved to average.
 Buick is the most reliable domestic brand, coming in at fifth place  overall. The Encore and redesigned Envision are both well-above average,  and the Encore GX is above average. Surprisingly, the Enclave drops to  below average, with transmission, drive system, and blank in-car  electronics screen issues.
 High Rankings for Several Domestic Models Mark Signs of Improvement for U.S. Manufacturers
 Models from five domestic brands, Buick, Chevrolet, GMC, Chrysler,  and Ford, take the top spots in seven categories--an unusually strong  showing. They include:
 - Buick Envision (Luxury Compact SUVs)
- Chevrolet Trailblazer (Subcompact SUVs)
- Chevrolet Silverado 2500HD and its twin the GMC Sierra 2500HD (Full-sized Pickups)
- Chrysler 300 (Midsized/Large Cars)
- Ford Bronco Sport (Compact SUVs)
- Ford Mustang Mach-E (Electric SUVs)
- Ford Ranger (Midsized Pickups)
CR’s data also shows that hybrids and plug-in vehicles are among the  most reliable models even though they have unusually complicated  drivetrains. These vehicles include the Honda Insight, Kia Niro and the  Toyota Prius, Prius Prime, RAV4 Prime, and Venza. One likely reason for  their reliability is that most of these are well-established models that  haven’t seen radical changes over the years. Even the new-for-2021  Venza uses a tried-and-true powertrain.
 The analysis also shows that fully-electric SUVs are among the least  reliable vehicles. They include the Tesla Model X and Y, Audi E-Tron and  Volkswagen ID.4. All have a high rate of problems in areas other than  the electric powertrain. Some of these problems include climate  controls, in-car electronics, and power equipment.
 Honda Ranks Sixth in Brand Rankings
 Honda ranks sixth among brands, down one from last year, with the  Insight scoring well-above average. The CR-V, Accord, and Ridgeline  score above average and the remaining models are all average. Both the  Passport and Odyssey have improved, though owners still report issues  with the infotainment system freezing and power equipment. Some Odyssey  owners also report problems with the sliding doors.
 Subaru comes in seventh overall. The Crosstrek is well-above average,  and the Legacy, Impreza, and Forester are above average. However, the  Ascent still has subpar reliability.
 Acura's rank is eighth overall. The TLX has exhibited impressive  reliability in its first year after a redesign, and the redesigned 2022  MDX has above average first-year reliability after below-average  reliability with its previous generation. The RDX improves from below  average to average, though it still has ongoing issues with brakes,  power equipment, and in-car electronics with the display screen freezing  and needing hardware replacement, and software updates failing.
 Nissan improves this year, moving up to ninth place--mostly because  of older models including the Rogue Sport, Murano, and Leaf, which show  impressive reliability.
 Mini rounds out the top 10, making it the highest-ranked European  automaker this year. Mini only has two models in the survey, the Cooper  Countryman and Cooper/Clubman, and jumps 13 places in the standing. The  jump is mainly attributed to its Cooper Countryman's outstanding  reliability.
 Hyundai falls four positions this year to rank eleventh. The  redesigned Tucson is well-above average, and the Sonata and Palisade are  also above average. The Kona Electric and freshened Santa Fe are below  average, with, respectively, battery pack and electric drive motor  problems, and transmission and power equipment issues. Kia drops three  to 19th place this year, with transmissions being the brand's weak spot.  The eight-speed dual clutch transmission that is used with the turbo  engine in the redesigned Sorento is problematic. Owners of the Soul,  Seltos, and Forte report a problem-prone CVT that could require  replacement. The Niro Electric improved and the Telluride remains  outstanding.
 Genesis’ reliability is suffering as the brand rapidly grows with new  models. While the G70 has improved to average, the new GV80 SUV scores  well-below average due to infotainment screen and drive system problems.
 Four Domestic Brands are Midpack
 Domestic brands are midpack or below--Chrysler at 12th, Chevrolet at  14, Cadillac at 16th, and Ford at 18th. Jeep, Tesla, and Lincoln took  the three bottom ranks. Chrysler has just two vehicles in the  survey--the 300, which has outstanding reliability, and the Pacifica  minivan, which is well-below average due to issues including the  transmission and sliding doors.
 Chevrolet models spread across almost the entire range of CR’s  reliability scale--some excellent and some subpar. The new Trailblazer  SUV and the Trax are both excellent. After years of respectable  reliability, the Bolt EV dropped to below average, due to battery  problems and electric drive failures, among other issues. The Silverado  2500HD and Blazer are above average. Others, including the Corvette and  redesigned Tahoe, are well-below average. GMC's rank dropped because of  similar problems as twin models from Chevrolet. The Sierra 1500, Yukon,  and Canyon are all below- or well-below average. GMC’s only  above-average vehicle was the Sierra 2500HD.
 Cadillac improved six spots this year, helped by the reliable XT5  SUV. The XT6 and XT4 are below- and well-below average, respectively.
 Ford is showing improvement this year, with the new Bronco Sport,  Mustang Mach-E, and Ranger all at the top of their classes for  reliability. But the redesigned F-150 scored below average, as did the  Escape. Both the Mustang and the Explorer are well-below average.
 Ram drops the most in CR’s brand ranking this year, sliding twelve  spots to 21st. While the Ram 2500 and 1500 are both average, the 1500  Classic (the previous generation 1500) has well-below average  reliability marked by problems with brakes, emissions systems, engine,  and power equipment. Jeep ranks 26 and among the bottom three brands.  The company’s most reliable model last year, the Gladiator, fell below  average. The Cherokee and Wrangler are both below average. The Wrangler  has issues with the drive system, in-car electronics, and, like the  similar Gladiator, with the steering and suspension. The Cherokee has  in-car electronics and some transmission issues.
 Tesla, with four models in the survey, is unchanged at second from  last. While Tesla’s Model 3 has average reliability, the Model Y still  has body hardware issues with the tailgate and door alignment, paint  defects, and multiple other problems. The Model X and Model S both have  body hardware, climate system, and in-car electronics problems.
 All Lincoln models have below-average reliability, with the Corsair  and Aviator being well-below average. They, along with the Nautilus,  have transmission, in-car electronics and power equipment problems.
 Mixed Bag for European Models
 Porsche ranks midpack at 13, down two from last year. The Cayenne and Macan have average and above-average reliability.
 Audi is unchanged at 15th. The A4 and A5 remain above average, and  are joined by the A6 and Q5. The Q7 is average, but the Q3 has  below-average reliability. The Q8 and E-Tron, both well-below average,  continue to have drive system and power equipment issues.
 BMW is in 17th, down four. The X5, 3 Series, 5 Series, and X3 all  have average reliability, but the redesigned 4 Series has subpar  reliability due to power equipment problems.
 Volvo is 20th overall, down one. The XC90 continues to score  well-below average, mostly due to issues with brakes, climate system,  and body hardware. The S60 dropped to below average this year also  because of multiple issues. The XC40 is average and the XC60 is now  above average.
 Mercedes-Benz is in 23rd, down two from last year. The only reliable  model is the GLC. The E-Class fell to below average and the GLE remains  well-below average, with numerous power equipment, climate system,  in-car electronics, and some engine problems.
 Volkswagen is at 24th overall, up 1 from last year. While the Atlas  and Jetta improved to average reliability, the Tiguan and the new ID.4  EV are both subpar.
