Both the Seltos and Trailblazer offer rear cross-traffic warning, but the Seltos S/EX/X-Line/SX has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Trailblazer’s Rear Cross Traffic Alert doesn’t automatically brake.

The Seltos’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Trailblazer doesn’t offer a driver alert monitor.

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

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Kia Seltos is safer than the Chevrolet Trailblazer:

	Seltos	Trailblazer
	Passenger
STARS	4 Stars	4 Stars
Neck Stress	127 lbs.	153 lbs.
Leg Forces (l/r)	144/44 lbs.	409/383 lbs.

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

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Kia Seltos is safer than the Chevrolet Trailblazer:

	Seltos	Trailblazer
	Front Seat
STARS	5 Stars	5 Stars
Abdominal Force	170 lbs.	199 lbs.
Hip Force	428 lbs.	459 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	13 inches	13 inches
HIC	225	337
Spine Acceleration	33 G’s	38 G’s
Hip Force	433 lbs.	591 lbs.

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 Seltos is 1% to 3.4% less likely to roll over than the Trailblazer.

Warranty

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

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

Reliability

A hardened steel chain, with no maintenance needs, drives the camshafts in the Seltos’ engine. A rubber cam drive belt that needs periodic replacement drives the Trailblazer’s camshafts. If the Trailblazer’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

J.D. Power and Associates rated the Seltos second among small suvs in their 2024 Initial Quality Study. The Trailblazer isn’t in the top three.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Kia vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Kia 10 places higher in reliability than Chevrolet.

Engine

The Seltos’ standard 2.0 DOHC 4-cylinder produces 9 more horsepower (146 vs. 137) than the Trailblazer’s standard 1.2 turbo 3-cylinder. The Seltos X-Line/SX’s standard 1.6 turbo 4-cylinder produces 40 more horsepower (195 vs. 155) and 21 lbs.-ft. more torque (195 vs. 174) than the Trailblazer’s optional 1.3 turbo 3-cylinder.

As tested in Motor Trend the Kia Seltos is faster than the Chevrolet Trailblazer 1.3 turbo 3-cylinder:

	Seltos 4 cyl.	Seltos X-Line/SX	Trailblazer
Zero to 60 MPH	8.3 sec	6.9 sec	9.3 sec
Quarter Mile	16.5 sec	15.4 sec	17 sec
Speed in 1/4 Mile	85.5 MPH	91.2 MPH	80.5 MPH

Fuel Economy and Range

On the EPA test cycle the Seltos gets better mileage than the Trailblazer:

			MPG
Seltos
	FWD	2.0 DOHC 4-cyl.	28 city/34 hwy
	AWD	2.0 DOHC 4-cyl.	27 city/31 hwy
Trailblazer
	FWD	1.2 turbo 3-cyl.	30 city/31 hwy
	AWD	1.3 turbo 3-cyl.	26 city/29 hwy

The Seltos has a standard locking fuel door. The fuel filler door is not lockable on the Trailblazer. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Brakes and Stopping

For better stopping power the Seltos AWD’s front brake rotors are larger than those on the Trailblazer:

	Seltos AWD	Trailblazer
Front Rotors	12 inches	11.81 inches
Rear Rotors	11.2 inches	10.39 inches

The Seltos stops shorter than the Trailblazer:

	Seltos	Trailblazer
70 to 0 MPH	160 feet	166 feet	Car and Driver
60 to 0 MPH	113 feet	121 feet	Motor Trend
60 to 0 MPH (Wet)	133 feet	135 feet	Consumer Reports

Tires and Wheels

The Seltos’ standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Trailblazer LS/LT/ACTIV’s standard 60 series tires.

Suspension and Handling

For superior ride and handling, the Seltos AWD has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Chevrolet Trailblazer has a solid rear axle, with a non-independent rear suspension.

The Seltos AWD has front and rear stabilizer bars, which help keep the Seltos AWD flat and controlled during cornering. The Trailblazer’s suspension doesn’t offer a rear stabilizer bar.

The Seltos 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 Trailblazer doesn’t offer variable-assist power steering.

The Seltos S AWD handles at .85 G’s, while the Trailblazer RS AWD pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The Seltos S AWD executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the Trailblazer RS AWD (26.7 seconds @ .65 average G’s vs. 28.3 seconds @ .57 average G’s).

For better maneuverability, the Seltos’ turning circle is 2.5 feet tighter than the Trailblazer’s (34.8 feet vs. 37.3 feet). The Seltos’ turning circle is 3.5 feet tighter than the Trailblazer RS’ (34.8 feet vs. 38.3 feet).

Passenger Space

The Seltos has .5 inches more front legroom, 1.2 inches more front hip room, .1 inches more front shoulder room, 2.4 inches more rear hip room and .9 inches more rear shoulder room than the Trailblazer.

For enhanced passenger comfort on long trips the Seltos’ rear seats recline. The Trailblazer’s rear seats don’t recline.

Cargo Capacity

The Seltos has a much larger cargo volume with its rear seat up than the Trailblazer with its rear seat up (26.6 vs. 25.3 cubic feet). The Seltos has a much larger cargo volume with its rear seat folded than the Trailblazer with its rear seat folded (62.8 vs. 54.4 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the Seltos easier. The Seltos’ cargo hatch lift-over height is 29.4 inches, while the Trailblazer’s liftover is 30.8 inches.

The Seltos’ cargo area is larger than the Trailblazer’s in almost every dimension:

	Seltos	Trailblazer
Length to seat (2nd/1st)	32.7”/62.4”	32”/64.5”
Max Width	52.3”	54”
Min Width	41.6”	41”
Height	32.5”	28.2”

Ergonomics

Optional air-conditioned seats in the Seltos SX keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Trailblazer doesn’t offer air-conditioned seats.

Both the Seltos and the Trailblazer offer rear vents. For greater rear passenger comfort, the Seltos has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Trailblazer doesn’t offer rear air conditioning vents, only heat vents.

The Seltos S/EX/X-Line/SX’s standard GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Trailblazer’s available navigation system doesn’t offer real-time traffic updates.
