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

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.

"Car has HID headlights, they were defective when I picked up the new car from the dealer, took over two years and three or four trips to the dealer before a new service manager swapped out the defective ? assemblies. PROBLEM High beams pointed into tree tops and low beams were too high causing me to blind other drivers at night,causing them to flash their brights at me, Got to the point I would not drive the car at night, Dealer said they could not be adjusted but was able to adjust them after which they were too low, took it back to dealer and had then adjusted back to factory settings, finally they replaced both left and right headlight assemblies under warranty with new ones cost $1600 each, $3200, plus labor had to take front end r assembly off car, now headlights are marginally acceptable, Low beams OK but not great, No flashing from other drivers, High beams still way too high but marginally functioning, they over shoot most distance objects road signs but light up the overhead freeway signs COOL but I would like the light on the Road, What A Concept This appears to be a design problem which I suspect has affected many drivers, made for dangerous night driving till they were replaced over TWO YEARS."

"It involved the "knock" sensor. In September the check engine light was flashing & the car would not go over 30 mph. New wiring harness was installed. Was fine until March 2, 2020. I was traveling from the Cleveland auto show home to Cincinnati. Luckily I was in a rest area when it happened. Car was towed (30mph doesn't cut it on I-71. The dealer reprogramed it said I could pick up the car & return the rental. Soon after they called to say the check engine light was blinking again. They brought me a 2020 Sonata SEL new off the lot as a courtesy car. I got my car back April 17. (much of the time delay was due to coronavirus chaos) Ultimately they replaced the knock sensor tested the car for 3 days & returned it to me.(2 hour drive each way) All of this was covered under warranty even though this car is out of warrantynow. Except for the coronavirus I would probably have lease a 2020 Sonata limited. I would not buy one in a redesign year. Sonata offers what others don't a lot of equipment & easy to use controls although the 2020 Limited controls are not as simple. Still those controlas beat Honda & Mazda. I'd buy a Camry, but I can't get a heated steering wheel, ventilated seats, etc. I would also only consider a 2017 or older Camry due to headlight ratings. But for now I'll keep the Sonata."
