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.

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.

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.

What Owners Say

Engine harness

"Faulty wiring for the engine knock sensor caused the car to go into "limp mode" when my wife and I were 600 miles from home. We had to leave the car in Charlotte, NC, for repair. Unfortunately, Hyundai had a huge backlog of vehicles with similar problems which meant we had to drive a rental car for nearly 3 months before our car was fixed and returned to us. Then, 48 hours after getting the car back, the engine light came on again. We took it back to your Hyundai dealer who kept the car for another 2 weeks before parts were available. Apparently, the technician in Charlotte wired the car incorrectly. After being without our new car for nearly 4 months, we got it back and it's been driving well ever since."

Anonymous, KY (2018 Hyundai Sonata Limited 2.4-L 4 Cyl)

"There was a recall to upgrade some software. After having that upgrade performed while on a 200 mile trip, the engine went into safety mode, not allowing me to drive over 50mph. I had to call for a tow, had to get an uber to take me to a separate location than my wife who went with the car. This all happened approximately 75 miles from home making it extremely inconvenient. The issue was with the wiring harness and the dealer had the car for 3 months since there were so many instances of this occurring. I was happy to have a loaner, but it was extremely irritating to not get updates from the dealer unless I called. They did not reimburse for the uber that I had to take to actually get a rental care for a day so that I could get to my destination. My wife had to miss the event altogether to take care of my car (she's a saint). Ultimately things were taken care of but it was a very frustrating event."
