Brand New, Bolt On, and the Theta II Recall

Many Theta II engines fell under a recall tied to rod bearing wear. Some of those engines seized. A brand new engine starts fresh, so you don't inherit worn bearings.

It's still a Theta II design, though. Regular oil changes matter. Read our Theta II recall explainer and check your VIN with Hyundai or Kia for open recalls. If you're curious how direct injection works, see What Is a GDI Engine?.

What's Included & Installation Notes

The engine ships as a complete package. It bolts in without modification. Even so, your mechanic should replace old gaskets and fluids as the service manual says. Ask us for the exact parts list before you buy, so nothing surprises you on install day.

Orders usually ship the same day, and we ship to 48 states. We also check fitment with you first. Browse more in our Brand New Engines and JDM Engines collections.

The engine block, cylinder walls, and cylinder head are also warrantied to be free of deep cracks or distortions that would otherwise render the engine incapable of operating under the original manufacturer's intended use of the product. The same applies to all internal accessories listed above.
  • DMV JDM Depot reserves the right to perform maintenance procedures including servicing and repairing their products prior to listing an item for public sale. This includes but is not limited to, using parts that are remanufactured, serviceable used parts or even exchanging the engine under the company's own discretion and determination if deemed necessary or otherwise detrimental to the original motor in its unmodified state.

ITEMS NOT COVERED UNDER WARRANTY

  • All external parts attached to the engines, e.g., intake and exhaust manifolds, carburetors, distributor, starter, emission control devices, flywheel, clutch and pressure plate, water pump, thermostat, belts, hoses, oil pan, valve cover, sensors, electronic parts(distributor, wires, Computers, injectors, etc.), drive shafts, engine mounts, half shaft, turbo(s), etc.
  • DMV JDM Depot reserves the right to refuse any claim regarding used motors that seize, lose critical amounts of compression, or suffer any other catastrophic failure during the warranty period due to negligence of the customer, or the customer’s mechanic. Used engines should always be monitored closely within the first 50 to 100 miles after installation to ensure that all components are functioning properly.
  • If the engine was installed by a certified mechanic, it is the mechanic’s responsibility to ensure that the engine is in good condition before releasing the vehicle to the customer. Professional installation is always recommended. For all warranty claims on our engines or transmissions, we require a valid Mechanic’s report, although this cannot override our warranty terms and discretion. We encourage the mechanic to contact us with any questions during the installation if he or she is unfamiliar with installing JDM replacement motors. Failure to install an engine through a certified mechanic or registered professional medium may result in voiding the warranty at the discretion of DMV JDM Depot.

Defective Product Claim Procedure

In the unlikely event of a Head/Block/Transmission being defective, we will require the following to be emailed to us:

  • DMV JDM Depot will require a detailed written description along with pictures and videos of the described defective part from a Certified Mechanic ONLY.
  • A copy of the Mechanic’s certification along with his/her contact information must be provided. DMV JDM Depot will contact the Certified Mechanic to ensure that the documents are legitimate. The Certified Mechanic may not be the individual who bought the engine from DMV JDM Depot. You may email the required paperwork to sales@dmvjdmdepot.com
  • Once the required paperwork is emailed, we will make a decision on whether we will provide a refund for the damaged part(s) only or request for the engine/transmission to be returned for a replacement. Shipping charges nor labor are covered under warranty. You must return the defective engine/transmission completely with no parts missing. If parts are missing, those parts will be removed from the replacement engine/transmission prior to being shipped.
