Compare the2025 Kia Carnival VS 2024 Buick Enclave

For enhanced safety, the front and second-row seat shoulder belts of the Kia Carnival have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Buick Enclave doesn’t offer pretensioners for its second-row seat belts.

The Carnival has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Buick Enclave doesn’t offer front seat center airbags.

For enhanced safety, the front seat shoulder belts of the Kia Carnival are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Buick Enclave doesn’t offer height-adjustable front seat belts.

The Kia Carnival has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Enclave doesn’t offer knee airbags.

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

The Carnival’s 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 Enclave doesn’t offer a driver alert monitor.

Both the Carnival and the Enclave have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

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

To reliably power the ignition and other systems and to recharge the battery, the Carnival has a standard 180-amp alternator. The Enclave’s 170-amp alternator isn’t as powerful.

The Carnival’s standard towing capacity is much higher than the Enclave’s (3500 vs. 1500 pounds).

Standard Trailer Stability Assist (TSA) on the Carnival uses the Electronic Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Enclave doesn’t offer electronic trailer sway control.

The Carnival EX/SX/Prestige’s front and rear power windows all open or close with one touch of the switches. The Enclave’s rear power window switches have to be held the entire time to close them fully.
