While the Sedona is priced at the low end of the minivan class, it doesn't miss any safety points. Anti-lock brakes, as well as stability and traction control, plus front, side, and side curtain airbags (that cover all three rows of seats), are all standard on the 2010 Sedona, and its performance in NHTSA and IIHS crash tests is top-notch.
Cars.com specifies that "all-disc antilock brakes incorporate electronic brake-force distribution." More safety features are available with the EX trim, according to Kelley Blue Book: "Stepping up to the Sedona EX adds fog lights...[and an] auto-dimming rearview mirror."
Newly standard on the LWB versions of the 2010 Kia Sedona is a backup warning system, though outward visibility is already quite good. Cars.com says that "the thick windshield pillars can impede visibility to front corners, but there are clear sightlines elsewhere." MyRide.com remarks, "Visibility rearward from the 2009 Kia Sedona's driver's seat is especially good, an important contribution to safety, because the rear window is as big as it can be, and the headrests over the five rear seats sink down to the tops of the seats." Visibility is excellent all around.
