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).
NA
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

Worse Better
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

This version of the Sonata ranked among our top-rated family sedans. The ride is supple, yet composed. Handling is agile and responsive. The Sonata's swoopy, coupe-like styling comes with tolerable rear-seat room and visibility. The revised four-cylinder engine racked up impressive fuel economy of 27 mpg overall. On the other hand, complaints include noticeable road noise and inhibited rear-seat access due to the low roof line.

The Sonata Hybrid (which we also tested) is a far cry from the conventional Sonata. Although it gets better fuel economy than its non-hybrid doppelganger, the trade-offs in drivability, refinement and braking performance are too high. The car stumbles and hesitates as it makes the transition from electric to gas power, with occasional shakes and vibrations.

Nina J., WI (2012 Hyundai Sonata GLS 2.4-L 4 Cyl)

"Failure of the temperature sensor totally disrupted the shifting. Would not shift up when it should and jerked suddenly. when it finally did shift. Engine was running at high RPM and wouldn't always shift down when slowing until car stopped. Why a temperature sensor should cause such an unreliable shifting is beyond me. I also thought it was a very expensive fix if it really was just the temperature sensor. They had to open up the transmission to get to it."

What Owners Say

Difficult to fill up gas tank

"About 1 year ago, the electric gas gauge stopped functioning properly. When the car was started, the gauge randomly indicated a position ranging from the actual level of fuel to "empty." This made it impossible to know what the actual fuel level was. The problem has not been resolved because my dealer would not fix it without charging me. I consider this a "defect" which should be corrected free of charge. In my 50+ years of driving, I have never had, nor ever heard of, a vehicle whose gas gauge failed to work."

Anonymous, CA (2012 Hyundai Sonata SE 2.4-L 4 Cyl)

"Our engine was knocking and pinging for a long time and then the engine just quit on the freeway. Even our battery died completely--the tow truck driver could not believe that our battery could be completely dead if we drove there. It appeared as though there was not oil in the engine. It turned out to be the Hyundai recall for the engine. Hyundai tried to claim no responsibility when we first took it in to their shop. After a week, they admitted some responsibility. Then we had to wait for confirmation from the main office. Then it took a month to get the new engine installed. They made us pay for a new battery, even though the battery was in perfect shape before the engine froze up. Horrible service and communication from the dealership. Moreover, with the software update, we may not be able to go over 60 miles per hour."
