Specs side by side
What owners say
Carnival
Overall
Mixed sentiment with a clear divide between short-term satisfaction and long-term confidence. Owners consistently praise the vehicle's spaciousness, smooth ride quality, modern technology, and superior interior design and materials compared to key competitors. The hybrid variant is noted for good fuel economy and strong availability, with dealers often more negotiable than Toyota counterparts.
Best version to buy
SX Prestige Hybrid (or similarly named high trim). This trim is frequently mentioned as offering the best combination of advanced features (e.g., 360-degree camera, premium audio, advanced driver assists) while including the hybrid powertrain.
Known issues
- ⚠Long-term reliability concerns: Very frequent mentions of anxiety over the vehicle's durability beyond 100,000 miles, citing Kia's historical engine problems (oil burning, connecting rod failures) and the unproven nature of the new hybrid…
- ⚠Hybrid system malfunctions: Isolated but severe reports of the hybrid system disengaging unexpectedly during highway driving, causing drastic deceleration. Linked in one case to a faulty heater/evaporator causing battery drain.
- ⚠Infotainment/electronic failures: Reports of dead infotainment display screens, body control module failures preventing engine start, and other electrical gremlins.
Sedona
Overall
Sentiment is mixed and heavily dependent on model year and generation. Long-term owners of earlier models (circa 2000-2009) frequently report achieving high mileage (150,000-225,000 miles) with only routine maintenance and minor repairs, describing them as surprisingly reliable and durable family vehicles. However, this positive view is countered by recurrent reports of significant, catastrophic engine failures in specific later models, most notably the 2017 model year, where engines have seized or thrown a rod around 100,000 miles despite proper maintenance.
Best version to buy
Insufficient owner data available to declare a definitive "best" model year or trim. Positive long-term reports span early 2000s models (e.g., 2005, 2006) and mid-2010s models (e.g., 2016, 2017).
Known issues
- ⚠Catastrophic engine failure (seized engine, thrown connecting rod): Reported specifically around 100,000 miles on 2017 models, with repair costs quoted around $13,000 USD. Frequency: recurrent.
- ⚠Premature brake wear: Frequent replacement of pads, rotors, and calipers mentioned across multiple generations. Frequency: recurrent.
- ⚠Interior durability concerns: Chrome trim peeling, hard plastics difficult to clean, interior rattles developing over time, and seat latching mechanisms for the rear bench becoming unreliable. Frequency: recurrent.
