Compare the2025 Kia SorentoVS 2024 Subaru Ascent

Both the Sorento and Ascent have child safety locks to prevent children from opening the rear doors. The Sorento S/EX/SX/Prestige/X-Line has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Ascent’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Sorento has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. Only the Ascent Premium/Onyx/Limited/Touring offers a blind spot warning system.

To help make backing out of a parking space safer, the Sorento has standard Rear Cross-Traffic Collision Warning and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. Only the Ascent Premium/Onyx/Limited/Touring offers Rear Cross Traffic Alert and the Ascent’s Rear Cross Traffic Alert does not include automatic braking.

Both the Sorento and the Ascent have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive and around view monitors.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a post at 20 MPH, results indicate that the Kia Sorento is safer than the Subaru Ascent:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Sorento is 1.1% less likely to roll over than the Ascent.

The Sorento comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Ascent’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

Kia’s powertrain warranty covers the Sorento 5 years and 40,000 miles longer than Subaru covers the Ascent. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Ascent ends after only 5 years or 60,000 miles.

There are over 23 percent more Kia dealers than there are Subaru dealers, which makes it easier should you ever need service under the Sorento’s warranty.

To reliably start during all conditions and help handle large electrical loads, the Sorento has a standard 760-amp battery. The Ascent’s 530-amp battery isn’t as powerful.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Kia vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks Kia fourth in initial quality, above the industry average. With 20 more problems per 100 vehicles, Subaru is ranked 12th.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Kia vehicles are more reliable than Subaru vehicles. J.D. Power ranks Kia above average in long-term dependability. With 3 more problems per 100 vehicles in the first three years of ownership, Subaru is rated below average.

The Sorento EX/SX’s standard 2.5 turbo 4-cylinder produces 21 more horsepower (281 vs. 260) and 34 lbs.-ft. more torque (311 vs. 277) than the Ascent’s 2.4 turbo 4-cylinder.

As tested in Consumer Reports the Sorento EX/SX 2.5 turbo 4-cylinder is faster than the Subaru Ascent:

On the EPA test cycle the Sorento gets better mileage than the Ascent:

In heavy traffic or at stoplights the Sorento’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Ascent doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Kia Sorento uses regular unleaded gasoline. The Ascent requires premium for maximum efficiency, which can cost on average about 84.9 cents more per gallon.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Kia Sorento higher (6 out of 10) than the Subaru Ascent (5). This means the Sorento produces up to 6.9 pounds less smog-producing pollutants than the Ascent every 15,000 miles.

The Sorento stops much shorter than the Ascent:

For better traction, the Sorento EX/SX’s tires are larger than the largest tires available on the Ascent (255/45R20 vs. 245/60R18).

The Sorento EX/SX’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Ascent Onyx/Limited/Touring’s 50 series tires.

The Sorento has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Ascent doesn’t offer variable-assist power steering.

The Sorento X-Line SX Prestige handles at .85 G’s, while the Ascent Limited pulls only .78 G’s of cornering force in a Motor Trend skidpad test.

The Sorento X-Line SX Prestige executes Motor Trend’s “Figure Eight” maneuver quicker than the Ascent Touring (26.5 seconds @ .67 average G’s vs. 27.4 seconds @ .63 average G’s).

The Kia Sorento may be more efficient, handle and accelerate better because it weighs about 400 to 600 pounds less than the Subaru Ascent.

The Sorento LX/S/EX/SX is 7.2 inches shorter than the Ascent, making the Sorento easier to handle, maneuver and park in tight spaces.

The Sorento has 3.1 inches more rear legroom and .6 inches more third row headroom than the Ascent.

The Sorento has a standard third row seat which folds flat into the floor. This completely clears a very large cargo area quickly. The Ascent doesn’t offer seats that fold into the floor.

Pressing a button automatically lowers the Sorento’s optional second row seats, to make changing between passengers and cargo easier. The Ascent doesn’t offer automatic folding seats.

To make loading groceries and cargo easier when your hands are full, the Sorento’s liftgate can be opened and closed just by waiting momentarily behind the back bumper, leaving your hands completely free. The Ascent doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The Sorento Prestige’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Ascent doesn’t offer an easy entry system.

The power windows standard on both the Sorento and the Ascent have locks to prevent small children from operating them. When the lock on the Sorento is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Ascent prevents the driver from operating the other windows just as it does the other passengers.

The Sorento Prestige’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Ascent’s rear power window switches have to be held the entire time to open or close them fully.

On a hot day the Sorento’s driver can lower all the windows from a distance using the keyless remote. The driver of the Ascent can only operate the windows from inside the vehicle, with the ignition on.

The Sorento has a standard Smart Key that allows you to unlock the doors from either front door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless Access and Start costs extra on the Ascent and isn’t available on the Ascent Base.

The Sorento’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Subaru only offers heated mirrors on the Ascent Premium/Onyx/Limited/Touring.

When the Sorento Prestige is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Ascent’s mirrors don’t automatically adjust for backing.

The Sorento is available in both front-wheel drive and four-wheel drive configurations. The Ascent doesn’t offer a two-wheel drive configuration.

Consumer Reports® recommends both the Kia Sorento and the Subaru Ascent, based on reliability, safety and performance.

The Kia Sorento outsold the Subaru Ascent by 46% during 2023.
