Kia and Hyundai Lemon Law: Theta II Engine Settlement Guide

A knocking or tapping noise from a Kia or Hyundai engine is not something to ignore. In some engines it has preceded a complete failure, and for many owners it starts a cycle of dealership visits for a problem that keeps coming back. Engine, transmission, and electrical conditions in these vehicles have produced federal penalties, two large engine class actions, and a string of recalls.

Kia and Hyundai lemon law protections help consumers who bought or leased a Kia or Hyundai with a persistent engine, transmission, or electrical condition that the dealership cannot fix in a timely manner. A vehicle that has been through a reasonable number of repair attempts, or has spent an unreasonable amount of time out of service, may qualify for a repurchase or a replacement. The engine class action settlements extended warranty coverage on many older vehicles, but they also affect your ability to bring your own claim, which this guide explains. Kahn & Associates represents owners in Ohio, Florida, Michigan, North Carolina, and Pennsylvania, and you are not required to pay us any out-of-pocket fees or costs, win or lose.

(A note on terms: there is no lemon law written specifically for Kia or Hyundai. The lemon laws apply to every manufacturer, and we use “Kia and Hyundai lemon law” as shorthand for a lemon law claim involving one of these vehicles.)

If your Kia or Hyundai has been in for repair for the same issue at least twice, or has been or will be out of service for at least 21 calendar days, call 1-888-536-6671 or request a free 60-Second Lemon Law Assessment today.

Understanding the Theta II Engine Settlement and Your Lemon Law Rights

The Recall Scandal and NHTSA Action

Many Kia and Hyundai owners have experienced sudden engine failure, stalling, or fire. In November 2020, the National Highway Traffic Safety Administration entered consent orders with the two companies totaling $210 million in civil penalties. The agency found that the companies had failed to recall more than 1.6 million vehicles with defective Theta II engines in a timely manner, and had provided inaccurate information to regulators about the defect.

Inside the Class-Action Agreements

Your Rights Under the Lemon Law

This is the part the settlements make complicated. Class members who did not opt out of a class action are bound by it. The Engine II settlement’s own notice states that anyone who wanted to pursue their own lawsuit over the same engine defect, including a lemon law claim, had to exclude themselves by August 7, 2023; class members who did nothing gave up the right to sue over the issues in that case. Engine I worked the same way, with earlier deadlines.

That does not end every claim. The releases cover the engine defect at issue, not every problem a vehicle might have, so transmission, electrical, and other unrelated conditions are not affected. Newer vehicles outside the class definitions are not affected either. And many of the vehicles covered by these settlements are now old enough that they fall outside state lemon law coverage windows in any event.

For a vehicle that does qualify, a lemon law claim can produce a repurchase or a replacement or cash settlement. A repurchase generally returns what you paid, including your down payment, monthly payments, taxes, and finance charges, less any mileage offset your state allows. Most of these claims resolve without going to court. To see whether your vehicle qualifies, you can learn what the lemon law covers. If your Kia or Hyundai has been in twice for the same issue, that is reason enough to ask us to review your repair history or call 1-888-536-6671.

What Are Common Kia and Hyundai Defects Beyond Engine Failure?

Dual-clutch transmission trouble

Engine defects get most of the attention, but transmission complaints are common as well. Many owners report shifting problems with the seven-speed dual-clutch transmission used in certain Hyundai Tucson, Elantra, and Veloster models. Drivers describe shuddering, delayed acceleration from a stop, and in some cases a loss of power. Hesitation when pulling into traffic is a genuine safety concern, not merely an annoyance. If your vehicle has these conditions, our Hyundai-specific lemon law guide goes into more detail on your options.

Electrical faults and fire hazards

Electrical malfunctions are another recurring category. Owners report dark infotainment screens, failed lighting, and safety systems that shut down unexpectedly. More seriously, some electrical conditions have caused engine compartment fires, leading to large recalls across several Kia and Hyundai models, including Sorento and Santa Fe variants. In a number of these recalls, the manufacturers advised owners to park outside and away from structures until the repair was completed. A vehicle prone to catching fire has an obvious safety defect.

These fire hazards are distinct from the engine class actions and from the theft issue discussed below. Other safety system failures, including seatbelts, airbags, and anti-lock brakes, can also support a claim when they occur under warranty and the dealership cannot correct them.

How the lemon law protects your rights

The conditions that most often support claims in these vehicles are persistent engine issues, transmission failures, and electrical malfunctions. Our Kia-specific lemon law guide covers the Kia side in more detail.

To qualify, a nonconformity must substantially impair the use, value, or safety of the vehicle, and the dealership must have had a reasonable opportunity to repair it. In most states that means three or four attempts at the same condition, or roughly 30 days out of service. You do not need to wait for those numbers before calling, though: two visits for the same problem, or 21 days in the shop, is enough to ask.

We represent drivers in Ohio, Florida, Michigan, North Carolina, and Pennsylvania. You are not required to pay us any out-of-pocket fees or costs, win or lose. When a claim resolves, our fee is typically paid by the manufacturer as part of the total recovery.

How Lemon Law Applies to Kia and Hyundai Vehicles

If your Kia or Hyundai has a condition that impairs its use, safety, or value and the dealership cannot timely fix it, you may have a lemon. State and federal lemon laws protect you when a vehicle spends more time at the dealership than is reasonable.

Understanding the core eligibility rules

Most states use two benchmarks. A vehicle that has been in three or more times for substantially the same condition often qualifies. A vehicle out of service for an unreasonable amount of time, commonly 30 or more days, can qualify on that basis alone.

Federal vs state lemon law protections

You are not limited to your state’s statute. Knowing the difference between federal vs. state lemon law protections can help you choose the right path.

State lemon laws can produce a repurchase or a replacement, but their coverage windows are short. The federal Magnuson-Moss Warranty Act reaches conditions that arise anywhere within the manufacturer’s warranty, which matters for Kia and Hyundai owners given the long powertrain coverage on these vehicles. Its remedy is usually compensation for the vehicle’s lost value rather than a repurchase. There is also a filing deadline so the longer warranty does not necessarily mean unlimited time to act.

Used cars and manufacturer warranties

Many people assume only new vehicles can qualify. Used vehicles can too. A common misconception is that the vehicle has to be under warranty right now. It does not. There may be an implied warranty claim as well as a claim for breach of the written warranty covering repairs already performed under it. What is needed is that repairs were made under the manufacturer’s warranty or the manufacturer’s extended warranty.

You are not required to pay us any out-of-pocket fees or costs, win or lose. We can help you find out whether your vehicle qualifies and explain the process. Contact us or call 1-888-536-6671.

Kia and Hyundai Lemon Law Protections in Ohio, Florida, Michigan, North Carolina, and Pennsylvania

Safety defects in these vehicles often draw federal investigations, but state and federal law decides the remedy. Each of our five states sets its own rules.

State-Specific Rules for Vehicle Defect Claims

To qualify for a repurchase, your vehicle generally has to meet your state’s presumption standard, and each state defines it differently.

Ohio lemon law offers the most routes. The presumption applies if, within the first year or 18,000 miles, any one of four things happens: substantially the same nonconformity has been subject to repair three or more times and still exists or recurs; the vehicle has been out of service for a cumulative total of thirty or more calendar days; there have been eight or more repair attempts across any combination of nonconformities; or there has been a single unsuccessful attempt at a condition likely to cause death or serious bodily injury. In the landmark Royster case, the Supreme Court of Ohio held that the thirty-day presumption applies even if the vehicle is later repaired.

The other four states use two routes rather than four. The Michigan lemon law looks to four repair attempts for the same defect or thirty days out of service. The North Carolina lemon law looks to four attempts or twenty business days out of service within any twelve-month period. The Pennsylvania lemon law and the Florida lemon law each look to three attempts or thirty days. Florida, Michigan, and North Carolina also require written notice to the manufacturer before the presumption attaches, which is the step owners most often miss.

Falling short of a presumption does not necessarily end a claim. It means the repair history has to show a reasonable number of attempts on its own rather than relying on the statutory shortcut and the federal lemon law can help in this instance. Our firm has a very high win rate and has handled these claims since 1996.

Understanding Mileage Offset Deductions

When a manufacturer repurchases a vehicle, most states let it deduct an allowance for the miles you drove. The formulas differ. Ohio allows no mileage offset in a repurchase or replacement, so you receive a full refund. Florida bases the offset on mileage at settlement. Michigan counts miles before the first repair plus any miles over 25,000. North Carolina uses mileage up to the date of the third repair attempt, or at the twentieth business day out of service if that comes first. Pennsylvania takes the lesser of 10 cents per mile at the first repair or 10 percent of the purchase price.

Our Proven Record with Lemon Law Cases

Manufacturers have teams of lawyers protecting their numbers. We know the tactics they use, we know the attorneys who represent them, and we know who to reach at the manufacturer to resolve a claim quickly. We can analyze your repair records and check the offset that applies. You are not required to pay us any out-of-pocket fees or costs, win or lose.

The Hyundai and Kia Immobilizer Settlement: Theft Vulnerability and Your Rights

Owners of many Kia and Hyundai vehicles found themselves facing a sudden theft problem after videos spread online showing how to start certain models with a USB cable. The cause was the absence of an engine immobilizer, a small chip that prevents a car from starting without the correct key.

Security flaws and the USB hack

Immobilizers had been standard across most of the industry for years, but many 2011 to 2022 Kia and Hyundai vehicles sold in the United States were built without one. The result was a nationwide wave of thefts affecting millions of vehicles.

The settlements

Two separate resolutions came out of it. A private consumer class action produced a settlement that included a free anti-theft software update and reimbursement of up to $300 for steering wheel locks for vehicles that could not receive the software, along with compensation for theft-related losses.

Separately, in December 2025, a coalition of state attorneys general reached a multistate settlement. As of the date of this article, it requires the companies to offer free zinc-reinforced ignition cylinder protectors for eligible vehicles and provides limited restitution to owners in participating states whose vehicles were stolen or targeted on or after April 29, 2025, despite the software update. Claims under that settlement are filed through the multistate immobilizer settlement website. Not every state participates, so check eligibility for your state there.

Theft Vulnerability and Lemon Law Claims

Owners often ask whether the missing immobilizer makes their vehicle a lemon. On its own, generally not. The lemon laws address a nonconformity to the manufacturer’s warranty that the dealership cannot timely repair, and a theft vulnerability designed into the vehicle is usually handled through the settlements above rather than a lemon law claim.

What does matter is the rest of the repair history. If the same vehicle has undergone multiple repairs or spent an unreasonable amount of time at the dealership for other conditions, those may support a claim. Our guide to what the lemon law covers explains the standard.

If your Kia or Hyundai has problems beyond the theft issue, you do not have to take on the manufacturer alone. Contact us or call 1-888-536-6671. You are not required to pay us any out-of-pocket fees or costs, win or lose.

What Are the Steps to File a Kia or Hyundai Lemon Law Claim?

Making a claim does not have to be hard. We have represented drivers against manufacturers since 1996.

Key steps

To win your case, you must follow a clear path. The manufacturer delayed their engine recalls for too long. Clear records help you prove your case and hold them accountable.

1. Keep your repair records. Save repair orders, invoices, and notes from each dealer visit. They show how many times the dealership tried to fix the vehicle. You do not need to organize them before calling us.
2. Talk to an experienced lawyer. Once the vehicle has been in twice for the same issue, or out of service for 21 days, have a lawyer who knows state and federal warranty law review the file. We can do that for free.
3. Make a formal claim. A demand is sent to the manufacturer, which starts the formal process.
4. Resolve the claim. Pursue a repurchase, a replacement, or a cash settlement. If the manufacturer will not resolve it, the claim can proceed in court or arbitration.

No out-of-pocket legal fees

You are not required to pay us any out-of-pocket fees or costs, win or lose. We can help you understand your federal or state lemon law protections to get the best outcome.

Many state lemon laws say attorney fees shall be paid by the manufacturer to a prevailing owner. The federal Magnuson-Moss Warranty Act says those fees may be awarded. In a negotiated settlement, the fee is typically agreed with the manufacturer as part of the total recovery rather than awarded by a court, as it would be after a trial verdict.

Frequently Asked Questions

Does Hyundai have a buyback program for defective vehicles?

There is no general buyback program, but state lemon laws require a manufacturer to repurchase or replace a vehicle it cannot fix after a reasonable number of repair attempts. A repurchase covers the purchase price, any lienholder, plus taxes and fees, less any mileage offset your state allows. In Ohio there is no offset.

How do I know if I am eligible for the Kia and Hyundai engine settlements?

It depends on your engine. Vehicles with Theta II GDI engines fall under the first settlement, which provides a lifetime warranty for connecting rod bearing failure. Vehicles with Theta II MPI, Nu GDI, or Gamma GDI engines, generally 2010 to 2021 models, fall under the second, which provides a 15-year or 150,000-mile extended warranty. According to Kia America, the second settlement covers inspections and engine repair or replacement for qualifying failures. As of the date of this article, the warranties remain in effect but most reimbursement claim deadlines have passed.

Can I get a replacement vehicle under the Kia and Hyundai lemon law?

Yes. If your vehicle qualifies, the manufacturer must offer a comparable new vehicle or a refund. Depending on your state, you may owe a mileage offset for the miles you drove. We can negotiate with the manufacturer on your behalf to reach a fair result.

What defects are covered under the Kia and Hyundai lemon law?

Any nonconformity that substantially impairs the safety, use, or value of your vehicle, occurring under the manufacturer’s warranty, that the dealership cannot fix in a timely manner. Common examples are engine failure, transmission shifting problems, and electrical conditions. Our guide on what the lemon law covers explains the standard in more detail.

Is filing a Kia or Hyundai lemon law claim worth it?

If your vehicle qualifies, usually yes. A successful claim produces a repurchase, a replacement, or cash compensation, and you are not required to pay us any out-of-pocket fees or costs, win or lose. When a claim resolves, our fee is typically paid by the manufacturer as part of the total recovery.

Ready to take the next step to fix your Kia or Hyundai issues?

A defective Kia or Hyundai that spends more time at the dealership than is reasonable is a safety concern and a standing source of frustration. Waiting can cost you, because every state lemon law has a defined window for reporting the condition and separate deadlines for bringing a claim.
