The KA4 Carnival replaces the Sedona and is the most contemporary family van/crossover available. The 3.5L Lambda V6 is Kia's most proven large engine and does NOT carry KSDS recall exposure. 8-speed automatic is smooth and well-sorted. Interior quality and features are outstanding for the price. Strong family vehicle value with minimal known failure modes.

Open recalls — VIN check
Campaigns vary by build date. Run the VIN at nhtsa.gov/recalls and require every open recall closed before purchase.
What the VIN tells you
Every U.S. 2022 Carnival (KA4) uses the same 3.5L Smartstream/Lambda III V6 GDI (290 hp) with an 8-speed automatic — there is no four-cylinder or hybrid option this model year (the Carnival Hybrid did not arrive until 2025), so the 8th VIN digit carries no engine-family ambiguity to decode. That is reassuring: this V6 is NOT part of Kia’s Theta II / KSDS engine-fire population, so the rod-bearing knock-sensor recall anxiety that haunts 2.0T and 2.4 Kias does not apply here. What the VIN still matters for is recalls — run the full 17-digit VIN at nhtsa.gov/recalls before purchase to confirm any open KA4 campaigns (early seat-belt-anchor and power-sliding-door actions) are closed. Decode the full VIN at autovetting.com/decode to confirm trim and build date.
