The Kia Sorento is one of the cars buyers browse most on Auto Bazar, and it is wanted for the same reasons as its sister, the Santa Fe: family space, an economical diesel and a reasonable price. But the Sorento carries a surprise its sister doesn't: its first generation is a structurally different vehicle from everything that came after. This guide starts there.
The first-generation Sorento (to roughly 2009) is built on a separate ladder chassis, with a transfer case on four-wheel-drive versions — four-wheel drive in the traditional sense. From the second generation on it became a unibody crossover, on a platform shared with the Hyundai Santa Fe. The difference is not a detail:
| Generation | Approx. years | Structure and what it means for you |
|---|---|---|
| BL | 2002–2009 | Separate chassis and transfer case: more capable off-road, heavier and thirstier, and older |
| XM | 2009–2014 | Unibody, with automatic all-wheel drive on 4x4 versions: more comfortable on paved roads, less capable on truly rough ground |
| UM | 2014–2020 | Larger and better equipped, and the most in demand among what is on offer today |
| MQ4 | 2020 onward | The newest and dearest; its electronics make a diagnostic scan essential |
If you genuinely drive rough roads, the question of generation comes before the question of price. If it is city driving and travel on paved roads, the newer generations suit better. See the SUV and 4x4 buying guide to settle the category before the model.
From the second generation on, the Sorento and Santa Fe share a platform and most engines. That helps you twice: it widens what is on offer if you also search Hyundai Santa Fe listings, and it means many engine and suspension parts are close between the two. For the sister model's specifics, see the used Hyundai Santa Fe buying guide.
The general inspection first — the complete checklist — then:
Generation, fuel and drive system explain most of the difference between one listing and the next, so compare within them only. Browse Kia Sorento listings, then estimate the value as in the market valuation guide. If there are signs of body repair, read warning signs of an accident-repaired car before going further.
Know which Sorento is in front of you: the first generation is a traditional 4x4 on a chassis, everything after it a crossover sister to the Santa Fe. Choose by your roads, not the looks, search both sisters' listings together, and give the diesel and engine their checks before you pay.
The first generation (to roughly 2009) is built on a separate chassis with a transfer case on four-wheel-drive versions — traditional four-wheel drive. From the second generation on it became a unibody crossover with automatic all-wheel drive on 4x4 versions: comfortable on paved roads, less capable on genuinely rough ground.
From the second generation on they share a platform and most engines, so many engine and suspension parts are close, and the main differences are in styling, cabin and equipment. The first-generation Sorento is structurally different, because it sits on a separate chassis.
The chassis from underneath for rust or weld marks, actually engaging the transfer case during the test drive, and any oil leaking from the differentials. Then the usual diesel items if it is a diesel: the cold start, smoke colour and turbo noise.
If you genuinely drive rough roads, the first generation with its chassis and transfer case is more capable despite its age and thirst. If your use is city driving and travel on paved roads, the XM and UM generations are more comfortable and newer, and the UM is the most in demand among what is on offer today.
