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
HUMMER LEMON LAW.
Hummer has not existed as its own brand since 2010. What exists now is the GMC Hummer EV — and roughly 30,000 of the 34,000 ever sold were delivered in the last two years, so almost the entire fleet is still inside its warranty window.

EXPLORE ↓Two Different Vehicles, One Name
Which Hummer do you have? The answer changes everything.
The standalone Hummer brand was wound down in 2010. The name came back in 2021 as a GMC sub-brand. Those are two different situations and only one of them has a live Lemon Law claim.
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.
If you own a GMC Hummer EV, you are a General Motors claimant. NHTSA files every current campaign under General Motors, LLC with the make recorded as GMC, and a demand letter names General Motors, not Hummer. US sales ran 854 in 2022, 3,244 in 2023, 13,993 in 2024 and 15,788 in 2025 — so roughly 30,000 of the 34,000 ever sold arrived in the last two years, and almost the whole fleet is inside a Lemon Law and warranty window right now.
If you own an H1, H2 or H3, the position is different and it is worth being straight about it. Those were built between 2003 and 2010 under the standalone brand, which General Motors wound down — the H2 ended in 2009 and the H3 and H3T in 2010. They are fifteen years or more past any state Lemon Law window.
That does not always mean nothing. Federal warranty law can reach a vehicle with active warranty coverage, and dealer misrepresentation or undisclosed damage at the point of sale is a separate matter entirely. But it is not a Lemon Law claim, and anyone telling you otherwise is wasting your time.

Recall or Claim
A recall says GM 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.
Most GM campaigns bundle the Hummer EV in with other GM nameplates, so there is no Hummer-only recall total to quote. One recent campaign covers only the 2026 Hummer EV SUV and Pickup: 354 vehicles whose front passenger airbag connection may have an improperly crimped wire.

WHAT KEEPS COMING BACK.
These are the defect categories that generate the most Lemon Law and warranty claims involving the GMC Hummer EV. A vehicle showing one of these is not automatically a claim. A vehicle showing one of these repeatedly and unrepaired usually is.
Battery Pack Water Ingress
An improperly sealed high-voltage battery pack enclosure lets water in and can cut drive power entirely, in a campaign covering the 2022 Hummer EV and 2023 Hummer EV Pickup.
Rear Drive Unit Wiring Short
Insufficiently insulated motor wires in the rear drive unit can touch and short, producing a loss of drive power severe enough that GM's remedy was full replacement of the rear drive unit.
Passenger Airbag Crimp Fault
An improperly crimped wire at the front passenger airbag connection can stop the airbag deploying in a crash, in a campaign covering 354 model-year 2026 Hummer EV SUV and Pickup vehicles exclusively.
Lighting and Radio Configuration
Taillight software that leaves rear lamps inoperative or permanently lit, and radio modules misconfigured at the factory, show a pattern of software-set functions failing at delivery rather than through use.
Service Brake Complaints
Service brakes rank among the top three NHTSA complaint categories for the Hummer EV across the 2024 and 2025 model years, alongside the electrical system and forward collision avoidance.
Electronic Owner's Manual Missing
Radios not configured in production to download the electronic owner's manual left owners without operating and safety instructions, a federal non-compliance covering 2026 Hummer EV models among other GM vehicles.

Not on its own. General Motors wound the standalone Hummer brand down in 2010 — the H2 ended in 2009, the H3 and H3T in 2010, and the H1 back in 2006. The name returned in 2021 as the GMC Hummer EV, a sub-brand of GMC. NHTSA files every current campaign under General Motors, LLC with the make recorded as GMC.
Almost certainly not, and it is better to hear that plainly. Those vehicles were built between 2003 and 2010, which puts them fifteen years or more beyond any state Lemon Law window. Federal warranty law can reach a vehicle with active warranty coverage, and dealer misrepresentation at the point of sale is a separate matter — but neither is a Lemon Law claim.
General Motors, LLC. A demand letter names General Motors, not Hummer and not GMC on its own. Every current campaign is filed under that entity with the make recorded as GMC, which is also why a search under "Hummer" at NHTSA returns very little. Look your VIN up under General Motors.
Very probably. US sales ran 854 units in 2022, 3,244 in 2023, 13,993 in 2024 and 15,788 in 2025 — so roughly 30,000 of the 34,000 ever sold were delivered in the last two years. Florida's rights period generally runs 24 months from delivery and New York's two years or 18,000 miles, which almost the entire fleet is still within.
No, and any figure claiming to be one is unreliable. Most GM campaigns bundle the Hummer EV with other GM nameplates, so the campaign totals are GM-wide rather than Hummer counts. One recent campaign is the exception: 354 vehicles covering only the 2026 Hummer EV SUV and Pickup, for an improperly crimped front passenger airbag wire.
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 Hummer 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.
