Hyundai and Kia Timing Chain Replacement Cost: Theta II and Nu Engines

Hyundai and Kia Theta II engines are known primarily for bearing failure and engine seizure, but timing chain issues also occur. Here are the costs and what to check for warranty coverage.

Cost by Engine

EngineTotal CostLabor
Theta II 2.0T$1,800 - $2,8008 - 11 hrs
Theta II 2.4L$1,500 - $2,5007 - 10 hrs
Nu 1.8L / 2.0L$1,200 - $2,0005 - 8 hrs

Theta II: Engine Problems Beyond the Chain

The Theta II 2.0T and 2.4L engines are known primarily for connecting rod bearing failure, which can cause engine seizure and, in some cases, engine fires. Hyundai and Kia have issued multiple recalls and warranty extensions covering millions of vehicles. The timing chain is a secondary concern on these engines.

However, when bearing wear occurs, metal particles contaminate the oil and accelerate chain and guide wear. If you have a Theta II engine that is consuming oil, knocking, or has a check engine light for oil pressure, the timing chain may be affected as well. In these cases, the engine replacement under warranty typically includes a new timing chain, so the chain itself may not need separate replacement.

For engines not affected by bearing failure, timing chain issues are uncommon before 100,000 miles with regular oil changes. When they do occur, the symptoms are the standard cold-start rattle and P0016/P0017 codes.

How to Check for Warranty Coverage

  1. 1. Check online: Visit hyundaiusa.com/recalls or kia.com/us/en/recalls and enter your 17-digit VIN. This shows all open recalls and campaign information.
  2. 2. Call your dealer: Provide your VIN and ask about the Theta II engine warranty extension. Under the 2021 settlement, Theta II GDI short blocks carry a lifetime warranty for original owners who completed the knock-sensor software update; coverage is 15 years / 150,000 miles for subsequent owners and certain other cases.
  3. 3. Check NHTSA: Visit nhtsa.gov/recalls for federal recall information. Multiple Theta II recalls are listed with specific affected VIN ranges.
  4. 4. Ask about the knock sensor detection update: Hyundai and Kia released a software update that monitors for bearing wear via the knock sensor. If your vehicle has not had this update, request it. It provides early warning of bearing failure.

Frequently Asked Questions

Is my Hyundai or Kia covered by a timing chain recall?
Hyundai and Kia have issued multiple recalls and extended warranty coverage for Theta II engine problems, but most of these cover bearing failure and engine seizure, not specifically the timing chain. Under the $1.3 billion class-action settlement (final approval June 2021), Theta II GDI engines received a lifetime warranty on the short block (engine block, crankshaft, bearings, connecting rods, pistons) for original owners who completed the knock-sensor (KSDS) software update; subsequent owners and certain other cases are covered to 15 years or 150,000 miles. A timing chain issue caused by engine bearing wear may be included. Contact your dealer with your VIN to check specific coverage. The recall campaign number for the Theta II engine warranty extension varies by model year.
How do I check my Hyundai or Kia VIN for warranty coverage?
Three ways: First, visit hyundaiusa.com/recalls or kia.com/us/en/recalls and enter your VIN. Second, call your local dealer service department and give them your VIN. Third, check NHTSA.gov/recalls for any open recalls. The Theta II engine warranty extension is the most relevant. Even if your specific issue is not listed, ask about goodwill coverage. Hyundai and Kia have been proactive about covering engine problems on these vehicles due to the scale of the issue.
Are Hyundai and Kia timing chains as bad as BMW or Ford?
No. Hyundai and Kia timing chain issues are secondary to the more publicized Theta II bearing failure and engine seizure problems. The chains themselves are reasonably durable and typically do not fail before 100,000 miles with proper maintenance. The bigger risk on these vehicles is the engine itself seizing due to metal debris from bearing failure contaminating the oil and damaging the chain system. If your engine has been replaced under warranty, the new engine will have a fresh chain.
