Engine Overview

The Hyundai Grandeur TG is available with 2 engine variants — from 150 to 165 hp.

2.2L CRDi · Diesel· 150–155 PS
2005 2010

Beefy diesel for big SUVs and vans. Chain-driven, strong torque, but turbos can wear over time.

  • !! Timing belt service interval from 90,000 km

    The D4EB uses a timing belt rather than a chain. Manufacturer recommends replacement every 90,000–96,000 km. Belt breakage leads to severe engine damage on this interference engine.

    Symptoms: No direct warning before breakage. Light rattling or squealing shortly before failure possible.

  • !! VGT turbocharger fails from soot deposits from 150,000 km

    The variable vanes of the VGT turbocharger stick due to soot deposits and get stuck in one position. The result is a severe power drop and limp mode.

    Symptoms: Severe power loss, turbo whistling, check engine light, black smoke from exhaust.

  • !! High-pressure pump leaks diesel into engine oil from 180,000 km

    On the D4EB the high-pressure pump can pump diesel into the engine oil via seal failure. The extremely elevated oil pressure can blow out seals and destroy the turbo.

    Symptoms: Rapidly rising oil level (diesel smell in oil), power loss, engine warning light, turbo failure.

2.4L (Theta) · Petrol· 164 PS
2005 2010

Theta NA with enough power for full-size sedans. Chain-driven, low running costs.

  • !! Oil sludge blocks connecting rod bearing galleries from 120,000 km

    Identical problem to the 2.0 Theta: metal swarf from manufacturing or sludge formation blocks oil galleries to the connecting rod bearings. This Theta defect cost Hyundai billions in recalls.

    Symptoms: Metallic knock (rod knock), oil pressure warning, sudden engine stop, metallic particles in oil.

  • !! Timing chain stretches — rattle and timing drift from 140,000 km

    The G4KC timing chain drive is designed for the full engine life, but in practice stretches with extended oil change intervals. A stretched chain can shift valve timing and provoke valve damage.

    Symptoms: Rattling on cold start, check engine light (cam phase fault), power loss, occasional misfires.

  • !! Timing chain stretch (early phase) from 120,000 km

    Early G4KC production showed problems with stretching timing chains that rattled and could jump. Particularly a risk with poor maintenance and extended oil change intervals.

    Symptoms: Rattling on cold start, engine noise on cranking, misfires from incorrect timing
