This three-row crossover splits into two completely different vehicles by generation. The 2011-2019 Theta II models are mechanical time bombs, engines grenade between 50k-90k miles with oil burning and rod knock, leaving families stranded for months while dealers work through warranty backlogs. The 2024 redesign threw out that cursed powertrain entirely, but introduced two new problems: panoramic sunroofs that explode while driving (glass raining into the cabin, corporate denying coverage), and a 2024 dual-clutch transmission already failing at low mileage. The 2026 hybrid with conventional automatic looks promising, owners report 470-mile range and Range Rover looks at $50k, but it's too new to trust long-term. If you're buying used, the Theta II era is a hard pass. If you're buying new, the hybrid might be worth the gamble, but skip the sunroof and prepare to fight corporate if anything breaks. Honda Passport and Mazda CX-90 offer less drama.
If you're shopping three-row SUVs and the Sorento catches your eye, know this: generation matters more than brand loyalty here. The 2011-2020 models earned their reputation the hard way, owners report needing two or three complete engine replacements before 110k miles, with Kia dragging its feet on warranty coverage until recalls forced action. The 2021-and-newer models fixed the engine drama but swapped it for DCT transmission failures in the turbocharged EX and higher trims, typically around 70k miles. The bright spot? The current Sorento Hybrid runs a bulletproof conventional six-speed automatic and delivers 32 mpg without the powertrain anxiety. It's genuinely competitive if you can live with a tighter third row than the Highlander offers and don't need to tow a boat. Skip the older generations entirely, and if you're buying new, either go Hybrid or stick with the base engine and transmission, the turbo DCT combo is a $6,000 repair waiting to happen.
