Powertrain stories on the ix35 depend on fuel and market.
Diesel
Short trips hurt DPF and EGR: faults, limp mode, smoke. Scan before buying; ask about regenerations and deletes. High-mileage injectors and the high-pressure pump are real cost items. Listen for turbo whistle and watch for oil in intake pipes.
Petrol
Misfires often track to coils/plugs after ruling out vacuum leaks. Oil use without external leaks needs compression and a scope, not endless top-ups. Fix cooling (cap, pump, thermostat, radiator) before blaming the bottom end.
Noise and ancillaries
Cold “diesel-like” tick can relate to timing tensioners — verify before it becomes a failure. Accessory rollers are cheaper than a broken belt. Valve-cover seepage is common; still track the dipstick.
Oil use + smoke + uneven compression → bore-scope before a blind rebuild. After purchase: oil/filters, pressure-test cooling, scan codes, loaded highway test.
