The 2024 Sorento is a mid-size seven-seat SUV; the diesel automatic pairing is tuned for motorway cruising and towing and will give good real-world economy on long runs. As with modern diesels expect a DPF and AdBlue system and an 8-speed automatic — both are reliable but deserve attention if the car has mostly short trips. Kia’s long factory warranty (commonly 7 years) often still covers 2-year-old examples, so check remaining cover and any dealer software updates.

• DPF and AdBlue behaviour — look for recent forced-regens, repeated warning lights or a pattern of short urban trips that can clog the DPF.
• Automatic gearbox shift quality — no harsh or delayed up/down shifts, and confirm major transmission fluid/interval work or software updates have been done per Kia schedule.
• 4WD/AWD operation (if fitted) — select drive modes, listen for transfer-case or differential noises and check for signs of heavy off-road or tow use under the car.
• Towbar and rear suspension condition — check for towball wear, corrosion around hitch fixings and any rear-spring sag or uneven tyre wear from towing.
• Third-row seats and ISOFIX mounts — verify they fold and lock smoothly and inspect seat runners/trim for damage from regular loading.
