Many have towed, so ask what and how often. ### Automatic Gearbox Judder or Slipping Owners report Sorento automatics that judder or shudder as they pull away, jerk or lurch between gears, or slip, especially on cars that have towed. On the test drive, pull away gently from a stop several times, accelerate firmly up a hill and drive through traffic. Feel for shudder, thumps between gears, revs rising without the car speeding up, and watch for a gearbox warning or sudden loss of power. Ask when the gearbox fluid was last changed and whether it's had any repairs or software updates, with receipts. If it judders or slips, have a mechanic check it before you buy. ### Oil Use and Engine Knock Some Sorento engines are reported to burn oil and, at worst, wear the bearings inside the engine, heard as a knock. An engine that runs low on oil can fail without much warning. Pull the dipstick: the level should sit between the marks. Ask how often it's topped up. Listen with the bonnet open for a knock that speeds up with the revs, and watch for blue-grey smoke at start-up. Ask whether the engine has been repaired or replaced, including under warranty or a recall, and get the paperwork. A knocking engine needs a mechanic before you buy; an engine replacement is a huge bill. ### AWD System Noise or Failure On AWD Sorentos, the part that sends drive to the rear wheels and the diffs can wear, causing whines, clunks or a car that only drives the front wheels. On the test drive, listen for a whine or hum from underneath that changes with speed. In a car park, drive slowly on full lock both ways: there should be no clunking or juddering. Check for an AWD warning on the dash. Ask whether the AWD parts or diff oils have been serviced, with receipts. Repairs can be expensive, so price a fault into your offer. ### Brake Vibration A heavy seven-seater, especially one that tows, is hard on brakes, and owners report vibration through the pedal or steering wheel as the brake discs wear unevenly. On the test drive, brake firmly from 80 km/h where it's safe. The car should stop straight, with no shaking through the pedal or steering wheel and no grinding. New discs and pads aren't a huge bill, but they're an easy one to take off the price. ## Which Kia Sorento Years to Avoid? No Kia Sorento year is one to avoid outright. Which problems a particular car has depends on its generation, its engine and how it was used, so judge the one in front of you rather than the year alone, starting with its recalls and reported faults (Shufti looks these up from the listing). - **XM (2009–2015).** Every one is now over 10 years old, so condition and history count for more than the year: look hard for rust, worn suspension and leaks, and check whether a timing belt (if it has one) has been replaced. - **UM (2015–2020).** Most have done enough kilometres for wear items to come due: check the service history for regular servicing, and whether tyres, brakes and the battery need replacing. - **MQ4 (2020 on).** The current model. The newest may still have some new-car warranty left; on older ones, check the service history and whether tyres, brakes and the battery are due. ## Kia Sorento Inspection Checklist Tick it if it's fine. Cross it if it isn't, and note what you found so you can price it into your offer. - Safety critical: Affects how safely it drives or protects you in a crash. Best to have a mechanic check it before you buy. - Negotiate: Costs money to fix, from wear to major repairs. Get a quote and take it off the price. ### Before You Go - [ ] **Get the VIN and rego** before you travel. A seller who won't share them is a red flag on its own. - [ ] **Know what you're looking at:** petrol, diesel, hybrid or plug-in hybrid (PHEV); 2WD or AWD. Diesel, hybrid and AWD checks below are marked. - [ ] **Ask how it was used:** family, towing a caravan or boat, dirt roads or short trips? - [ ] **Ask for the engine to be cold,** go in daylight, and bring a torch, paper towel and a friend. ### Exterior - [ ] **Panels and paint.** Uneven gaps, mismatched colour or overspray on seals and trim mean crash repair. (Negotiate) - [ ] **Hail and dents.** Look along the roof, bonnet and tailgate at a low angle to the light. (Negotiate) - [ ] **Bumpers and wheels.** Parking scrapes and kerbed alloys. A badly kerbed wheel can be bent, causing vibration. (Negotiate) - [ ] **Lights, glass and sensors.** All lights work, no condensation inside; windscreen free of chips; sensors and cameras undamaged. (Negotiate) - [ ] **Tailgate** opens, shuts and locks cleanly; a power tailgate (if fitted) runs smoothly. (Negotiate) - [ ] **Towbar.** A worn tow ball means lots of towing; check the wiring plug works. (Negotiate) - [ ] **VIN plate** (in a door frame or under the bonnet) is there, untouched, and matches the papers. ### Under the Bonnet - [ ] **Engine oil** between the dipstick marks, brown not black. Ask how often it's topped up between services. (Negotiate) - [ ] **Diesel: oil level** not above the top mark, and not smelling of diesel. A rising level usually comes from short trips interrupting the exhaust filter's self-clean. (Negotiate) - [ ] **Coolant** at the mark and brightly coloured. Rusty or oily coolant, or regular top-ups, needs a mechanic. (Negotiate) - [ ] **Brake fluid** (small tank at the back of the engine bay) is clear to light amber, not dark. (Negotiate) - [ ] **Belts, hoses and battery.** No cracked belts or swollen hoses. A weak 12V battery can stop a hybrid starting. (Negotiate) - [ ] **Leaks.** Wet oil on the engine or turbo pipes is a leak. (Negotiate) - [ ] **Cold start.** Starts easily and settles to a smooth idle. Knocking that speeds up with the revs needs a mechanic before you buy. (Negotiate) ### Underbody and Wheels - [ ] **Tyres** above the wear bars, worn evenly and under ~6 years old. AWD models need four matching tyres; mismatched ones strain the AWD system. (Negotiate) - [ ] **AWD:** no oil leaking from the rear axle or drive parts underneath. (Negotiate) - [ ] **Rust and crash repairs.** Rust on the floor or around the suspension; bent metal, fresh welds or new black coating in one spot. (Safety critical) - [ ] **PHEV: underfloor battery.** Dents, scrapes or damage to the large flat battery case under the floor. (Negotiate) - [ ] **Scrapes and drips.** Dents underneath from dirt roads; drips where it's normally parked. (Negotiate) - [ ] **Suspension and brakes.** Oily shock absorbers, a sagging rear; deep grooves or a raised edge on the brake discs. (Negotiate) - [ ] **Diesel: exhaust.** Heavy black soot at the tailpipe can mean a damaged or removed exhaust filter (DPF). (Negotiate) ### Interior and Electrics - [ ] **Warning lights.** Key to "on": every dash light comes on, then goes out once running. An airbag, brake, engine or hybrid warning that stays on needs explaining. (Safety critical) - [ ] **Every seatbelt** (up to seven) pulls out fully, retracts and latches, with no fraying. (Safety critical) - [ ] **Seats.** Middle row slides and folds; third row folds and locks. Stains, tears and broken latches show a hard family life. (Negotiate) - [ ] **PHEV: electric range.** Fully charged, note the range shown. A range well below what it had new can mean a worn battery. (Negotiate) - [ ] **Air con** blows cold front and rear, without a musty smell; heater gets hot. (Negotiate) - [ ] **Electrics.** Screens, Bluetooth/CarPlay, cameras, sensors, windows and sunroof. Count the keys. (Negotiate) ### Test Drive - [ ] **Automatic.** Smooth changes with no slipping, shudder or thump into Drive or Reverse. Towing wears autos; ask when the fluid was changed. (Negotiate) - [ ] **Hybrid or PHEV.** Moves off smoothly on electric power, and the engine joins in with no surges, cut-outs or warnings. (Negotiate) - [ ] **Engine.** Pulls strongly with no stutter, flat spots or smoke. Diesel: ask how often the exhaust filter light has come on. (Negotiate) - [ ] **Brakes.** Firm pedal; stops straight with no pulling, pulsing or grinding. (Safety critical) - [ ] **Steering and suspension.** Drives straight; no knocks over bumps or clunks through the wheel. (Negotiate) - [ ] **Noises.** A hum that grows with speed (wheel bearing), or a whine from the rear (AWD). (Negotiate) - [ ] **Afterwards,** check for new drips, a steady temperature gauge and no hot smells. (Negotiate) ### Documentation - [ ] **Seller's ID** matches the rego papers, and the VIN matches on the papers and VIN plate. - [ ] **Service history.** Logbook stamped on time, with receipts. Heavy towing should mean extra gearbox and AWD servicing. (Negotiate) - [ ] **Engine work.** Ask whether the engine has ever been replaced or repaired under warranty, and get the paperwork. (Negotiate) - [ ] **PHEV: charging gear.** The portable charging cable is included and works. (Negotiate) - [ ] **Warranty.** A newer Sorento may still be under Kia's new-car warranty. Check the start date and that servicing kept it valid. - [ ] **Rego and roadworthy.** Rego checked online; roadworthy supplied if your state requires one on sale. (Negotiate) ## Stay Safe Never go under a car held up only by a jack, and never open the radiator or coolant cap on a hot engine. Keep hands, hair and loose clothing clear of fans and belts when the engine is running, and do checks under the bonnet with it switched off where you can. On the test drive, hold a current licence, confirm the car is registered and insured, obey road rules, and only brake hard when the road behind is clear. Meet in a safe, public-facing place, take someone with you, and don't carry large amounts of cash to a viewing. ## Disclaimer Shufti is not affiliated with or endorsed by Kia; Kia and Sorento are trademarks of Kia Corporation.

It depends more on the particular car than the badge: how it was driven, loaded and serviced. Work through the commonly reported problems above, read the service history for servicing done on time, and run a PPSR check. ### Which Kia Sorento years should I avoid? No Kia Sorento year is one to avoid outright. Which problems a particular car has depends on its generation, its engine and how it was used, so judge the one in front of you rather than the year alone, starting with its recalls and reported faults (Shufti looks these up from the listing). This checklist covers the XM (2009–2015), UM (2015–2020) and MQ4 (2020 on) Kia Sorento. Problems reported across them include automatic gearbox judder or slipping, oil use and engine knock, AWD system noise and brake vibration. ### How many kilometres is too many for a used Kia Sorento? Kilometres matter less than how the car was driven and serviced. A high-kilometre SUV with a full service history can be a better buy than a low-kilometre one that's missed services, done short trips or been used for rideshare. Check the history for regular servicing, and on a hybrid ask for a battery health check. ### Should I get a pre-purchase inspection on a used Kia Sorento? It's worth it if you can. All-wheel-drive and hybrid systems can hide faults that only a mechanic's tools will show. Most buyers don't book one, though, so whatever you decide, check the car thoroughly yourself with this checklist first. See Is a pre-purchase inspection worth it? (https://shufti.com.au/guides/is-a-pre-purchase-inspection-worth-it) ### How do I check a used Kia Sorento for money owing or a write-off? Run a PPSR check with the car's VIN. It shows whether there's finance owing and whether the car has been reported stolen or written off, and costs $2. Run it on the day you pay. See What a PPSR check covers and what it doesn't (https://shufti.com.au/guides/what-is-a-ppsr-check) --- Shufti is an Australian used car inspection app for iPhone and Android that tailors the inspection to the exact car you're looking at. It is not affiliated with Shufti Pro, the identity verification (KYC) company. From the listing link, it builds every check around that car's make, model and year, odometer reading and the seller's description. It runs PPSR and government recall checks, crosschecks a database of more than 3 million recalls and owner complaints, flags problems from your photos and audio, plans a test drive, produces a shareable report with repair cost estimates, and coaches you through the negotiation. A check costs $24.99, or $49.99 for three, including PPSR and recall checks. A mechanic's pre-purchase inspection costs $250–350.
