Revised for 2018, the Hyundai Sonata keeps much of what makes it a strong competitor against such big dogs as the Honda Accord and Toyota Camry, while making some notable enhancements. Look beyond the freshened skin, and you'll find a Sonata with sharper handling and better braking than before, but the ride has become considerably firmer.

Road Test Results

Performance
Acceleration Acceleration Acceleration tests are conducted on a smooth, flat pavement straightaway at the track. Time, speed, and distance measurements are taken with a precise GPS-based device that’s hooked to a data-logging computer.
0 to 60 mph 0 to 60 mph (sec.) The time in seconds that a vehicle takes to reach 60 mph from a standstill with the engine idling.
Transmission Transmission Transmission performance is determined by shifting smoothness, response, shifter action, and clutch actuation for manual transmissions.
Braking Braking The braking rating is a composite of wet and dry stopping distances and pedal feel. Braking distance is from 60 mph, with no wheels locked.
Emergency Handling Emergency Handling Several factors go into the rating, including the avoidance maneuver speed and confidence, as well as how the vehicle behaves when pushed to its limit.
Comfort / Convenience
Ride Ride Our expert judgment of how well the suspension isolates and absorbs road imperfections and how steady it keeps the body on various road surfaces.
Noise Noise Our expert judgment of the vehicle's interior noise level in everyday driving.
Front Seat Comfort Front Seat Comfort Our judgment of how comfortable the front seat is for drivers of various heights.
Rear Seat Comfort Rear Seat Comfort Our judgment of how comfortable the rear seat is for two passengers to sit across.
Interior Fit and Finish Interior Fit and Finish An expert evaluation of the interior quality and craftsmanship.
Trunk/Cargo Area Trunk/Cargo Area Our rating is based on the amount of luggage or cargo space that a vehicle has in the trunk or cargo area.
Fuel Economy & Emissions
Fuel Economy Fuel Economy We perform our own fuel-economy tests, independent of the government's often-quoted EPA figures and the manufacturers' claims. Using a precise fuel-flow measuring device spliced into the fuel line, we run two separate circuits to represent city and highway consumption.
CR's Overall Mileage CR's Overall Mileage CR's overall mileage is a composite of measured fuel usage on a prescribed city course and highway cruising; and CR's 150-mile test trip of mixed driving, if tested. In recent road tests, we've discontinued the 150-mile trip test.
CR's City Mileage CR's City Mileage Measured fuel usage on a prescribed city course.
CR's Highway Mileage CR's Highway Mileage Measured fuel usage on a prescribed highway cruising.
Annual Fuel Cost Annual Fuel Cost The cost and amount of fuel used in 12,000 miles and is calculated from CR's overall mileage.
Greenhouse Gas Greenhouse Gas The Greenhouse Gas Rating represents the amount of carbon dioxide the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).
Smog Rating Smog Rating The Smog Rating represents the amount of health-damaging and smog-forming airborne pollutants the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).

Owner Reports

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Road Test

Revised for 2018, the Hyundai Sonata keeps much of what makes it a strong competitor against such big dogs as the Honda Accord and Toyota Camry, while making some notable enhancements. Look beyond the freshened skin, and you'll find a Sonata with sharper handling and better braking than before, but the ride has become considerably firmer.

The Sonata is an easy car to live with, thanks to its easy-to-use controls and an upright stance that affords easy access and good visibility. The cabin is roomy, boasting one of the most generous rear seats in the class. The standard 2.4-liter four-cylinder engine smoothly delivers sufficient pep without sounding like it's being flogged, making the Sonata reasonably quick. The six-speed automatic transmission makes well-timed shifts with nary a hiccup. However, its 28 mpg is nothing special as some competitors get 30 mpg or better. On the other hand, the hybrid version gets 39 mpg overall in our testing and can propel itself on electric power alone at low speeds. A much more powerful 2.0-liter turbocharged four-cylinder engine comes on high-end Sonatas.

Owner Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2019 Hyundai Sonata owners. The owner comments describe problems respondents experienced with this vehicle.

Transmission Minor

Gear selector or linkage, leaks, transmission computer, transmission sensor or solenoid, clutch adjustment, rough shifting, slipping transmission.

What Owners Say

Rough shifting

"Transmission shifts too early. At 1300 rpm in 5th and 6th gear at 36 and 47 mph respectively. At those speeds and rpms the engine shakes mildly, indicating the need to downshift. Not a major problem but I never had a car with auto trans that was this unrefined."

Anonymous, IL (2019 Hyundai Sonata Sport 2.4-L 4 Cyl)

Paint/Trim

Paint (fading, chalking, cracking, or peeling), loose interior and exterior trim or moldings, rust.

What Owners Say

Paint (fading, chalking, cracking, or peeling)

"Paint Chipping became apparent in the first 2 weeks of ownership, only on the hood. Since that time the problem has become very bad and there are 40 noticeable chips on the hood. Usually paint chips will occur on the leading edge of the hood from hard rock strikes, and the plastic fascia and grille area will show significant markings too. However they were occurring over the entire hood panel and there are almost none on the front fascia. The dealership noted that this was usual wear and tear and not covered under warranty. I work as a seat engineer for a major OEM and have a background in materials science. I spoke with the paint quality engineer at my company and when they looked at my car they immediately noted the problem was not wear and tear but due to poor adhesion between the primer and base coat (color). This was likely a processing issue at the plant where the paint chemistry was not managed properly for my specific vehicle. I have since contacted Hyundai Quality directly and they have acknowledged the problem! The thought that there could be many more vehicles like mine from Hyundai on the road with dissatisfied customers and dealerships that won't give the problems a second thought really disturbs me."
