Both the Telluride and Ascent have child safety locks to prevent children from opening the rear doors. The Telluride 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.

Both the Telluride and Ascent have rear cross-traffic warning, but the Telluride has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Ascent’s Rear Cross Traffic Alert doesn’t automatically brake.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Telluride is 1.5% to 2.7% less likely to roll over than the Ascent.

The Kia Telluride has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Ascent is only a standard “Top Safety Pick” for 2025.

The Telluride 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 Telluride 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 24 percent more Kia dealers than there are Subaru dealers, which makes it easier should you ever need service under the Telluride’s warranty.

To reliably start during all conditions and help handle large electrical loads, the Telluride has a standard 800-amp battery. The Ascent’s 530-amp battery isn’t as powerful.

J.D. Power and Associates rated the Telluride third among upper midsize suvs in their 2024 Initial Quality Study. The Ascent isn’t in the top three in its category.

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 Telluride’s 3.8 DOHC V6 produces 31 more horsepower (291 vs. 260) than the Ascent’s 2.4 turbo 4-cylinder.

As tested in Consumer Reports the Kia Telluride is faster than the Subaru Ascent:

To lower fuel costs and make buying fuel easier, the Kia Telluride 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 Telluride higher (6 out of 10) than the Subaru Ascent (4). This means the Telluride produces up to 12.1 pounds less smog-producing pollutants than the Ascent every 15,000 miles.

For better stopping power the Telluride’s front brake rotors are larger than those on the Ascent:

The Telluride stops much shorter than the Ascent:

The Telluride has standard front and rear gas-charged shocks for better control over choppy roads. The Ascent’s suspension doesn’t offer gas-charged shocks.

The Telluride has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The Ascent doesn’t offer a load leveling suspension.

For better handling and stability, the track (width between the wheels) on the Telluride is 2.8 inches wider in the front and 3.4 inches wider in the rear than on the Ascent.

The Telluride SX 4x4 handles at .81 G’s, while the Ascent Limited pulls only .79 G’s of cornering force in a Car and Driver skidpad test.

The Kia Telluride may be more efficient, handle and accelerate better because it weighs about 150 to 300 pounds less than the Subaru Ascent.

As tested by Car and Driver, the interior of the Telluride SX 4x4 is quieter than the Ascent Touring:

The Telluride has 1.1 inches more front hip room, .5 inches more front shoulder room, .2 inches more rear headroom, 3.8 inches more rear legroom, .8 inches more rear hip room, .9 inches more rear shoulder room and 1.9 inches more third row headroom than the Ascent.

The Telluride’s cargo area provides more volume than the Ascent.

A low lift-over cargo hatch design makes loading and unloading the Telluride easier. The Telluride’s cargo hatch lift-over height is 30.7 inches, while the Ascent’s liftover is 32 inches.

The Telluride’s cargo area is larger than the Ascent’s in almost every dimension:

Pressing a button automatically lowers the Telluride’s 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 Telluride’s liftgate can be opened 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 Telluride uses gas struts to support the hood for easier service access. The Ascent uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The power windows standard on both the Telluride and the Ascent have locks to prevent small children from operating them. When the lock on the Telluride 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 Telluride’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.

Consumer Reports rated the Telluride’s headlight performance “Very Good,” a higher rating than the Ascent’s headlights, which were rated “Good.”

The Telluride EX/SX has standard front air conditioned seats and the Telluride SX Prestige also has them in the second row. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The Ascent doesn’t offer air-conditioned seats for the second row.

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

The Telluride will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Telluride will retain 57.67% to 58.24% of its original price after five years, while the Ascent only retains 54.18% to 55.67%.

According to The Car Book by Jack Gillis, the Telluride is less expensive to operate than the Ascent because typical repairs cost much less on the Telluride than the Ascent, including $157 less for a starter and $270 less for front struts.
