the only problem the sportage has is the stupid "Interheater" sitting on top of the engine and the pump calibrated incorrectly to the turbo pressure - and to top it all, the extremely super loud fan.
Remedy
Place intercooler in front of vehicle
retune pump LDA and starwheel for proper fuelling
replace fan clutch with a softer fan clutch or electric fan
The reason why their engines fail is because people do not realise that the engine (sourced from Mazda) uses 2 oil filters - they never replace the second one and it gets packed with crap then pushes the crap into the engine because it is forced to run in bypass mode.
Never had any problems after the above mentioned mods and maintenance tips - got living happy examples of them
