01
Substantial Defect
One that impairs the use, value or safety of the vehicle. Stalling, brake failure, steering and persistent electrical faults qualify. A rattle generally does not.
By Manufacturer
HYUNDAI LEMON LAW.
Hyundai's Theta II engines seize. Its forward collision system brakes for nothing. Its EV charging unit stops charging until the car loses power. And if you drive a Genesis, every one of those campaigns is filed under Hyundai.

EXPLORE ↓What Decides It
Four facts, in this order.
Hyundai built it, but Hyundai does not decide it. These four questions decide it, and the repair orders in your glovebox answer all four.
02
Repair Attempts
Florida looks for three attempts at the same defect. New York looks for four. Recall work and visits that found nothing both count.
03
Days Out of Service
Thirty cumulative days in Florida and in New York. Cumulative, not consecutive, and the days count whether or not anything was fixed.
04
Coverage Window
The defect has to be reported while the vehicle is inside the warranty or rights period. When it was reported matters more than today's date.
Hyundai owns two of the best-documented defect programmes in the American market. The Theta II engine settlement — connecting-rod bearing wear causing seizure, stalling and fire — added 2.1 million vehicles and a 15-year, 150,000-mile warranty extension for that failure. The anti-theft settlement with 35 attorneys general covers every 2011-2022 Hyundai built without a factory immobiliser.
Genesis claims run under Hyundai. Genesis is Hyundai's luxury division and Genesis VINs sit inside Hyundai Motor America's own campaigns — the G90 in the 294,448-vehicle seat belt anchor recall, the GV60, GV70 Electrified and G80 Electrified in the 145,642-vehicle charging unit recall. A Genesis claim is a Hyundai Motor America claim.
One condition on the Theta II settlement is worth knowing and is easy to miss: the knock-sensor software update generally had to be performed within 150 days of settlement notice to keep access to the extended warranty. Owners who skipped it may have lost coverage they did not know they had.

Recall or Claim
A recall says Hyundai knows. A claim says they were given the chance to fix it.
A recall is the manufacturer acknowledging that a defect exists across a population of vehicles and offering a remedy. It is a public admission of the fault pattern, which makes it useful evidence. What it is not is a Lemon Law claim.
The claim arises from what happened to your vehicle: the defect was reported, the dealership was given a reasonable number of attempts to repair it, and it is still there. With Hyundai there is usually plenty of documentation to point at — the difficulty is that owners assume a settlement replaces a claim. It does not.
A class settlement extends a warranty. It does not buy your vehicle back, and it does not stop you pursuing a Lemon Law or warranty claim on a vehicle that has been in and out of the shop for the same unresolved fault.

WHAT KEEPS COMING BACK.
These are the defect categories that generate the most Lemon Law and warranty claims against Hyundai. A vehicle showing one of these is not automatically a claim. A vehicle showing one of these repeatedly and unrepaired usually is.
Theta II Engine Seizure
Connecting-rod bearing wear in Theta II 2.4L, Nu 2.0L and Gamma 1.6L GDI engines causes seizure, stalling and fire. A class settlement added 2.1 million vehicles and a 15-year, 150,000-mile warranty extension.
Phantom Emergency Braking
Forward collision-avoidance software misreads the front camera and brakes for no reason. Campaign 26V316 covers 423,062 model-year 2025-2026 Tucson, Tucson Hybrid, Tucson PHEV and Santa Cruz vehicles.
EV Charging Unit Failure
The Integrated Charging Control Unit stops charging the 12-volt battery until the car loses propulsion. Recall 24V868 covered 145,642 Ioniq 5, Ioniq 6 and Genesis EVs after 57 US incidents.
Seat Belt Anchor Detachment
Front seat belt anchors can pull free of the seat frame and fail to restrain occupants in a crash. Campaign 26V218 covers 294,448 Santa Fe, Santa Fe Hybrid, Ioniq 6 and Genesis G90 vehicles.
Instrument Cluster Blackout
A software fault blanks the instrument panel so the speedometer, tire-pressure readout and warning lamps disappear. Campaign 26V400 covers 96,310 model-year 2025-2026 Tucson variants.
Missing Engine Immobilizer
Model-year 2011-2022 Hyundais built without factory engine immobilizers are trivially stolen. A December 2025 settlement with 35 attorneys general forced free ignition-cylinder protectors and immobilizers on future vehicles.
Where It Ends Up
Four ways a Hyundai claim resolves.
Which one applies depends on the state, the facts and what gets negotiated with Hyundai. All four start with the same free case review.

Against Hyundai Motor America. Genesis is Hyundai's luxury division and Genesis VINs sit inside Hyundai's own NHTSA campaigns — the G90 appears in the 294,448-vehicle seat belt anchor recall, and the GV60, GV70 Electrified and G80 Electrified in the 145,642-vehicle charging unit recall. Look your VIN up under Hyundai, not Genesis.
Connecting-rod bearing wear in Hyundai's Theta II 2.4L, Nu 2.0L and Gamma 1.6L GDI engines, which causes the engine to seize, stall and in some cases catch fire. A class settlement added 2.1 million vehicles, extended the warranty for that failure to 15 years or 150,000 miles, and provided repair reimbursement and towing costs. It generally covers model years around 2010 to 2021.
A settlement extends a warranty. It does not buy your vehicle back and it does not bar a Lemon Law or warranty claim on a vehicle that has been in and out of the shop for the same unresolved fault. One condition catches people out: the knock-sensor software update generally had to be done within 150 days of settlement notice to keep access to the extended coverage.
Yes. Campaign 26V316, filed May 2026, covers 423,062 model-year 2025-2026 Tucson, Tucson Hybrid, Tucson Plug-In Hybrid and Santa Cruz vehicles, where a front-camera software defect makes the forward collision-avoidance system apply the brakes prematurely and unexpectedly. Unintended braking in traffic impairs the use and safety of the vehicle.
It may be. Recall 24V868 covered 145,642 Ioniq 5, Ioniq 6 and Genesis EVs whose Integrated Charging Control Unit can be damaged and stop charging the 12-volt battery, causing a loss of drive power. It was the second, expanded recall for the same defect after 24V204 — and a recall that had to be reissued is documentary evidence that the first repair did not work.
No. A recall is the manufacturer acknowledging that a defect exists across a population of vehicles and offering a remedy. A Lemon Law claim arises from what happened to your specific vehicle: a substantial defect, reported inside the coverage period, that the manufacturer was given a reasonable number of attempts to repair and did not. The recall is useful evidence within that claim, not a substitute for it.
Yes, where the recall remedy addressed the defect at issue and the fault persisted afterward. Owners frequently leave recall visits out of their own count because the work was free and manufacturer-initiated, which weakens the record unnecessarily. If the vehicle went in for the fault and came back with the fault, it was an attempt.
Florida's presumption generally arises after three repair attempts for the same defect, or after the vehicle has been out of service for 30 or more cumulative days during the Lemon Law rights period. A separate and earlier trigger applies at 15 cumulative days, when written notice goes to the manufacturer. It is a presumption rather than a fixed requirement — a defect serious enough to be dangerous can qualify with fewer attempts, and the presumption is one route to the remedy rather than the only one.
New York generally looks for four repair attempts for the same defect, or 30 or more days out of service, within the first two years or 18,000 miles. The framework is close to Florida's but the thresholds and the arbitration process differ, and a vehicle bought in one state and serviced in another needs the applicable law identified early.
One that impairs the use, value or safety of the vehicle. Stalling, brake failure, steering faults and persistent electrical problems clearly qualify. A rattle or a trim complaint generally does not. Between those extremes the answer depends on how the fault affects the vehicle in normal use, and on what the repair orders actually say about it.
State Lemon Law is primarily directed at qualifying new and demonstrator vehicles. A used Hyundai can still carry rights where a manufacturer or dealer warranty was active when the defect was reported, generally under federal warranty law including the Magnuson-Moss Warranty Act, which does not carry the same new-vehicle limitation.
A leased vehicle can be covered where it meets the same substantive requirements that apply to a purchase. The calculation of any refund is tied to the amounts actually paid into the lease rather than the full vehicle price, and the leasing company is dealt with as part of the resolution rather than left to be sorted out afterward.
That visit still counts as a repair attempt. Intermittent faults are extremely common in software, camera and electrical systems, and a growing share of manufacturer campaigns are software-related. A record of repeated visits where the fault was reported and not resolved is precisely the pattern the law addresses. Ask for the complaint to be written down in your words, and keep the copy that says it could not be verified.
Three, in practice. A repurchase, where the manufacturer buys the vehicle back and refunds what was paid, less a statutory offset for the miles driven before the first report of the defect. A replacement with a comparable vehicle. Or a cash settlement where the vehicle stays with you and the manufacturer pays for the diminished value. Which applies depends on the state, the facts and what is negotiated.
Broadly: the purchase price plus collateral and incidental charges, minus a mileage offset tied to the distance driven before the defect was first reported. Registration, taxes and finance charges are frequently recoverable. The offset is the part manufacturers most often calculate in their own favour, and it is worth checking line by line.
Other Manufacturers
The badge does not decide the claim.
The law applies the same way to every brand sold in the state. What differs is the defect pattern, the warranty terms and how hard the manufacturer fights.
