Complaint volume by model year. Raw NHTSA totals, not adjusted for sales volume or time on the road, so older and higher-selling years accumulate more. Every year links to its full breakdown.
Highest: 2025 (187 complaints). Lowest: 2023 (51).
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.
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 powertrain.
Reports of dead infotainment display screens, body control module failures preventing engine start, and other electrical gremlins. Parts for repairs (e.g., infotainment cluster) can be on prolonged backorder.
Recurrent criticism of Kia dealership service departments, described as underwhelming, potentially predatory, and difficult to work with for warranty claims.
The hybrid system has a required maintenance item (HSG belt replacement) approximately every 40,000 km (25,000 miles), adding to long-term service cost.
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.
