Hyundai and Kia have agreed to settle multiple class action lawsuits over defective engines that posed a fire hazard to owners, resulting in two major settlements totaling over $2 billion combined. The first settlement, covering the Theta II GDI engines, was approved for $1.3 billion with final court approval granted on May 10, 2021, while a separate Engine II settlement valued at $760 million received final approval on April 5, 2024. These settlements stem from a widespread manufacturing defect in gasoline direct injection and multipoint fuel injection engines that caused premature connecting rod bearing wear, which could lead to catastrophic engine failure and fires while vehicles were in use.
For vehicle owners who have experienced engine problems or fires related to these defects, the settlements offer compensation through extended warranties, repair reimbursements, and direct payments. An owner of a 2013 Hyundai Santa Fe with a Theta II GDI engine, for example, could receive an extended 15-year/150,000-mile warranty covering all repairs and parts related to the engine defect, along with reimbursement if they had already paid for repairs out of pocket. However, it’s critical to understand that one settlement deadline has already passed: the Engine II settlement claims deadline of July 8, 2024, means those particular claims are no longer available to file.

What Caused the Engine Fire Defect in Hyundai and Kia Vehicles?
The defect centers on manufacturing problems in Theta II GDI and MPI engines used across multiple model years and vehicle types. During production, contaminants or improper machining allowed connecting rod bearings to wear prematurely, leading to metal-on-metal friction inside the engine. This bearing wear can progress silently over thousands of miles until the rod suddenly fails, causing internal engine damage, loss of power, and in many cases, engine fire. The defect has been documented in Hyundai Elantras, Santa Fes, Sonatas, and Tucson models, as well as Kia Optimas, Souls, Sportages, and Foresters, primarily affecting vehicles manufactured between 2011 and 2019.
The severity of this defect distinguishes it from routine engine problems. Unlike a failing water pump or worn gasket that typically gives warning signs, connecting rod bearing failure can occur suddenly with minimal advance notice. Vehicle owners have reported engine fires occurring while driving on highways at normal speeds, creating a serious safety risk not just to the occupant but to other drivers and passengers on the road. Some owners discovered the problem only after an engine caught fire or seized completely, leaving them stranded with a vehicle that could not be safely driven.

The Theta II GDI Settlement and 15-Year Extended Warranty
The Theta II GDI settlement provides comprehensive coverage through a 15-year/150,000-mile extended warranty that covers all inspection, repair, replacement parts, labor, and even cosmetic or mechanical damage caused by the engine defect. This warranty extends beyond the manufacturer’s original coverage, meaning owners who experienced engine problems or fires after their standard warranty expired can still seek repairs at no cost. An owner who had a Theta II engine fire in 2019 and paid $4,500 out of pocket for engine replacement could potentially recover that expense through the settlement, in addition to the new extended warranty protection for future defect-related issues.
It’s important to note that while this warranty is extensive, it is not retroactive for all damage. The settlement specifically covers defects in the connecting rod bearing system, but an owner would need to demonstrate that their engine problem stemmed directly from this defect rather than other mechanical failures. Additionally, the 15-year warranty only applies if you continue to own the vehicle; once you sell the vehicle, the warranty protection transfers to the new owner but is only valid for the remaining time on the 15-year clock from the original vehicle purchase date.
The Engine II Settlement and Lifetime Warranty Coverage
The second settlement, approved in 2024 and effective May 29, 2024, covers Engine II defects and offers different benefits than the Theta II settlement. This settlement includes a lifetime warranty against the engine defect (though it does expire when you sell the vehicle), software installation designed to detect and prevent engine defects, reimbursements for repair costs already incurred, compensation for lost vehicle value, and compensation for repair delays. This means an owner of an affected Kia with an Engine II defect could receive payment for the depreciation their vehicle suffered due to the engine problems, in addition to repair coverage.
However, a critical limitation applies to the Engine II settlement: the claim deadline of July 8, 2024, has already passed. If you owned an affected vehicle and did not submit a claim by that date, you can no longer participate in this settlement. This is a hard deadline with no extensions, and many owners were unaware of the settlement or the deadline. If you missed this deadline, your only potential remedies would be pursuing an individual lawsuit or relying on Hyundai’s goodwill warranty repairs, neither of which guarantees the same level of compensation.

Who Is Eligible and How to Check Your Vehicle
To determine if your Hyundai or Kia vehicle qualifies for one of these settlements, you need to check your vehicle identification number (VIN) against the specific model years and models covered. The Theta II GDI settlement generally covers 2011-2019 Hyundai and Kia vehicles with GDI or MPI engines, though specific model years vary by model line. If you still own your vehicle and it has the defective engine, you can contact an authorized Hyundai or Kia dealership to verify eligibility and begin the warranty registration process.
For owners who have already sold their vehicle or are uncertain about their eligibility, the process becomes more complicated. You would need to provide proof of ownership during the relevant time period and documentation of any repairs performed. Comparing settlements: owners of Theta II engines have the advantage of an active extended warranty they can still register for, while Engine II owners missed the claims deadline and can no longer receive settlement benefits unless they can prove extraordinary circumstances prevented them from filing on time. Some owners have successfully challenged missed deadlines by showing they received no notice of the settlement, though this requires legal assistance.
Canadian Settlement and International Considerations
A related settlement was approved by the Supreme Court of British Columbia on November 28, 2025, covering similar engine defects in Hyundai and Kia vehicles sold in Canada. The claim deadline for the Canadian settlement is May 19, 2026, meaning Canadian owners still have time to file claims. The Canadian settlement provides comparable benefits to the U.S. settlements but operates under Canadian law and has different procedures for submitting claims and receiving compensation. One limitation of the Canadian settlement that mirrors the U.S.
situation is that not all affected vehicles may be included. The court approval specifies particular model years and engine types, and vehicles outside those specifications would not qualify, even if they experience identical problems. Additionally, if you are a U.S. citizen or resident who purchased and registered a vehicle in Canada, or vice versa, determining which settlement applies and which deadline is relevant can be complex and may require legal guidance. Owners in this situation should not assume they can claim benefits under both settlements.

Documentation Needed to File a Claim or Warranty Registration
Submitting a claim or registering for warranty benefits requires specific documentation that proves your vehicle ownership and the defective engine. You will need your vehicle’s VIN, proof of ownership (title, registration, or proof of insurance from the relevant time period), service records showing any repairs performed for engine problems, and receipts or invoices if you paid out of pocket for repairs. Having organized records significantly speeds up the claim process; missing documentation can result in claim denial or delays.
For example, an owner who kept detailed maintenance records and had repairs performed at an authorized dealership typically has an easier time proving their engine experienced defect-related problems compared to an owner who had repairs done at an independent shop or who didn’t keep records. Even if you eventually resolve the claim, the process can take several months, so documentation should be submitted as soon as possible. If you lack original receipts, dealership service records can sometimes be obtained by contacting the dealership directly and requesting your service history, though this works best if the dealership still operates and retains electronic records.
What Happens Next and Monitoring the Situation
The settlements as currently approved are considered closed or largely resolved, meaning no major changes to the available benefits are expected unless additional claims or legal challenges arise. However, vehicle owners should stay informed about their warranty coverage and any recalls issued by Hyundai or Kia related to these engine defects. Manufacturers sometimes issue technical service bulletins or recalls that supersede or modify settlement benefits, and owners need to be aware of these updates.
Looking forward, owners of vehicles with these engines who have not yet experienced problems should consider registering for or claiming warranty benefits now rather than waiting until an engine problem develops. The longer you wait, the closer you move toward the maximum mileage or age limits of the coverage, and unexpected engine problems can occur at any time. Staying proactive—keeping up with scheduled maintenance, monitoring engine performance, and maintaining warranty documentation—remains the best strategy for managing the risk posed by these defective engines.
Conclusion
The Hyundai and Kia engine fire defect settlements represent substantial compensation efforts by the manufacturers, totaling over $2 billion combined across multiple settlements. Owners of affected vehicles have access to extended warranties, repair reimbursements, and direct compensation for vehicle damage and depreciation, providing meaningful protection against one of the most serious defects to affect modern vehicles. Understanding which settlement covers your specific vehicle, whether you still have time to file a claim, and what documentation you need to submit are essential steps to receiving the benefits you may be entitled to.
If you own or previously owned a Hyundai or Kia with one of the affected engines and have questions about your eligibility or how to file a claim, contact the settlement administrator or an attorney specializing in class action settlements. For Canadian owners, the May 19, 2026, deadline for the Canadian settlement means there is still time to act, but U.S. owners should be aware that the Engine II settlement deadline has already passed. The sooner you verify your eligibility and take action, the sooner you can ensure your vehicle and finances are protected under these settlements.
