Hyundai's reputation for affordability means many owners keep their cars well beyond warranty, but certain engine families dominate replacement demand: the Theta II GDi petrol units (2.0/2.4L) and CRDi diesel engines (1.6/2.0L). Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to address the original failure...
Theta II GDi Bearing Failure
Most affected vehicles
Hyundai Tucson, Santa Fe, i40, Sonata (2011-2019, G4NA/G4NC/G4KJ 2.0L & 2.4L GDi)
Failure mileage range
60,000-100,000 miles
Typical failure window
Root cause
Inadequate oil flow to the connecting rod bearings combined with tight manufacturing tolerances causes accelerated wear, especially under short-trip driving or delayed oil changes.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| | Minor - Preventative Oil System Upgrade | £800 - £1,400 | £400 - £750 | | Fit upgraded oil catch can, high-flow oil pump gear, and switch to low-SAPS synthetic oil; does not reverse existing bearing wear. | Only viable if caught before knocking starts; extends life by ~20-30k miles if driven gently. | |
| | Intermediate - Bearing Replacement (Engine-Out) | £3,500 - £5,500 | £1,800 - £2,800 | | Remove engine, replace connecting rod bearings, inspect/machine crankshaft, renew oil pump and seals; requires precision torque specs. | Restores reliability if crankshaft is undamaged; not recommended if knocking has occurred for >100 miles. | |
| | Full Replacement - Rebuilt Theta II Engine | £5,000 - £7,500 | £2,200 - £3,500 | | Supply & fit of reconditioned engine with upgraded bearings, piston rings, and oil pump; bench-tested, ECU reset, 12-month warranty included. | Best value for cars worth £4k+; eliminates recurrence risk with upgraded internals and full warranty coverage. |
Our recommendation
On a Tucson or Santa Fe worth £4,000-£8,000, we rarely recommend bearing-only repairs once knocking is audible - the risk of hidden crank damage is too high. A rebuilt Theta II with upgraded components from our network delivers peace of mind and often costs less than a dealer-led partial repair.

The 1.4-litre CRDi diesel was Hyundai's entry-level oil-burner for small hatchbacks, most commonly fitted to the i20, i30 and ix20 from the early-2010s. Built around the D4FC engine family, these units are generally robust but can suffer from EGR and DPF-related issues when used predominantly on short trips - a failure pattern that often leads owners to seek replacement rather than repeated repairs

Performance / model premium
High-output models command a premium due to specialist components, lower supply volumes and more complex fitting.
Running cost comparison
Diesel can suit motorway mileage, petrol often suits shorter trips, and hybrid or electric value depends on charging habits.
