The Sienna comes standard with a Pre-Collision System with Pedestrian Detection (PCS w/PD), Lane Departure Alert with Steering Assist (LDA w/SA), Automatic High Beams (AHB), Full-Speed Dynamic Radar Cruise Control (DRCC), Road Sign Assist (RSA), and Lane Tracing Assist (LTA).

Kia has its own suite of active safety features called Kia Drive Wise. It has features like Lane Departure Warning (LDW), Smart Cruise Control (SCC) w/ Stop & Go, and Forward Collision-Avoidance Assist (FCA) w/ Pedestrian Detection. However, these features are not available for the base model Sedona LX. They are standard on the SX, however, which has a starting MSRP of $41,500.

These include a driver and front passenger Advanced Airbag System, driver, front passenger and second-row outboard seat-mounted side airbags, driver knee airbag, front passenger seat-cushion airbag, and side curtain airbags. The 2021 Sedona has Dual Front Advanced Airbags, Dual Front Seat Mounted Side Airbags, and Full-Length Side Curtain Airbags. However, it lacks a driver knee or 2nd row seat airbags.

The Sienna also has standard Blind Spot Monitor (BSM) with Rear Cross-Traffic Alert (RCTA) which is not available on the base trim Sedona LX.

Amenities are an important part of any vehicle, but a minivan has to have enough to keep the whole family satisfied. That's why the Toyota Sienna has standard three-zone, with available four-zone, automatic climate control with air filter, individual temperature settings for driver, front passenger and rear-seat passengers, and separate rear digital control panel. The Kia Sedona only has separate controls for the front and rear passenger areas. To get Tri-Zone Front and Rear Automatic Climate Control you'd have to get the Kia Sedona EX or SX.

For easy access to third-row seating, the 2021 Sienna has a super-long-slide seat feature with a seat travel of 25 inches. This feature is also convenient whether you're getting the kids out of their car seats or just want extra legroom.

You can also enjoy SiriusXM® with a 3-month All Access trial in this minivan packed with connectivity options.
