Iowa Lemon Law (2026): How to Qualify and Get a Refund

Iowa Code Chapter 322G, the Defective Motor Vehicles Act, gives buyers and lessees of new vehicles under 15,000 pounds a lemon presumption after three repair attempts for the same defect, one attempt for a serious safety defect, or 30 cumulative days out of service, all within two years or 24,000 miles of delivery. The consumer has an unconditional right to choose a full refund over a replacement vehicle.

Overview of the Iowa Lemon Law

Iowa's lemon law is officially titled the Defective Motor Vehicles Act and is codified in Iowa Code Chapter 322G. The Iowa General Assembly enacted this law to protect consumers who purchase or lease new motor vehicles that fail to conform to the manufacturer's express warranty after a reasonable number of repair attempts.

Under this law, the consumer has an unconditional right to choose between a replacement vehicle and a full refund when a vehicle qualifies as a lemon. The Iowa Attorney General's office administers consumer resources and provides forms to help Iowans navigate the claims process.

What Vehicles Are Covered

Under Iowa Code Section 322G.2, a "motor vehicle" is a self-propelled vehicle purchased or leased in Iowa that is primarily designed for the transportation of persons or property over public streets and highways. The vehicle must weigh under 15,000 pounds gross vehicle weight rating.

The in-Iowa purchase requirement is not absolute. Section 322G.15(2) extends the chapter (with narrow exceptions for Section 322G.3, subsections 1 and 2, and Section 322G.6, subsection 1) to vehicles originally purchased or leased in another state, as long as you are an Iowa resident at the time you assert your rights.

Covered Vehicle Types

• Passenger cars: Sedans, coupes, hatchbacks, and similar passenger vehicles
• Trucks: Pickup trucks and light trucks under 15,000 pounds
• SUVs and vans: Sport utility vehicles and passenger vans
• Electric and hybrid vehicles: EVs and hybrids that meet the weight requirement
• Leased vehicles: Leases of one year or more under a written agreement that makes the lessee responsible for repairs
• Transferred vehicles: Vehicles transferred during the lemon law rights period to someone the warranty entitles to enforce it

Vehicles Not Covered

• Motorcycles: Two-wheeled motor vehicles
• Autocycles: Three-wheeled enclosed motor vehicles
• Mopeds: Low-speed motor vehicles
• Motor homes: Recreational vehicles designed for living quarters
• Vehicles over 15,000 pounds: Heavy-duty commercial vehicles
• Vehicles acquired for resale or to lease out: A buyer or lessee whose purpose is reselling the vehicle or leasing it to someone else is not a consumer under Section 322G.2(3)

Who Qualifies as a Consumer

Section 322G.2(3) defines a "consumer" as the purchaser or lessee, other than for purposes of lease or resale, of a new or previously untitled motor vehicle, or any other person entitled by the terms of the warranty to enforce the obligations of the warranty during the lemon law rights period.

Chapter 322G contains no personal, family, or household use requirement. A business, farm, or fleet buyer that acquires a qualifying vehicle under 15,000 pounds for its own use is a consumer under the statute, the same as an individual driver. What the definition excludes is acquiring the vehicle in order to resell it or to lease it out to others.

The Lemon Law Rights Period

Iowa law defines a "lemon law rights period" that sets the window during which problems must arise for the vehicle to qualify. The rights period is the shortest of these three benchmarks:

• The term of the manufacturer's written express warranty
• Two years after the date of original delivery to the consumer
• The first 24,000 miles of operation

All nonconformities must be reported to the manufacturer or its authorized service agent within this rights period.

When a Vehicle Is Presumed to Be a Lemon

Under Iowa Code Section 322G.4, a rebuttable presumption arises that the manufacturer has not made a reasonable number of repair attempts when any one of these conditions is met during the rights period:

What Counts as a Nonconformity

A "nonconformity" is a defect, malfunction, or condition that fails to conform to the terms of the manufacturer's express warranty and either:

• Substantially impairs the use or market value of the motor vehicle, or
• Renders the vehicle unfit, unreliable, or unsafe for ordinary use

Examples of Qualifying Defects

• Engine or transmission failures that recur after repair
• Brake system malfunctions affecting stopping ability
• Steering defects that compromise vehicle control
• Electrical system failures that affect operation or safety
• Fuel system leaks or defects
• Air conditioning or heating system failures
• Airbag or other safety equipment malfunctions
• Persistent check-engine or warning lights tied to major systems

Important Note on Days Out of Service

The 30-day threshold counts only days the vehicle is with the manufacturer or authorized service agent for nonconformity repairs. Days spent on routine maintenance prescribed by the owner's manual do not count toward this total. The days do not need to be consecutive.

Consumer Remedies: Refund or Replacement

When a vehicle meets the lemon law presumption, the manufacturer must, within 40 days of receiving the consumer's payment of a reasonable offset for use, provide either a replacement vehicle or a full refund. The consumer has an unconditional right to choose a refund rather than a replacement under Iowa Code Section 322G.4.

Option 1: Full Refund (Buyback)

When the consumer elects a refund, the manufacturer must return the following amounts:

• Full purchase price: The complete cash price paid for the vehicle
• Trade-in allowance: The net value given for any trade-in vehicle
• Collateral charges: Sales tax, title fees, license and registration fees, and dealer-installed options
• Finance charges: All interest and financing fees paid
• Incidental costs: Towing charges and rental car expenses caused by the defect

Option 2: Replacement Vehicle

If the consumer chooses replacement instead, the manufacturer must provide a comparable replacement vehicle that is:

• Acceptable to the consumer
• Of similar value and features
• Covered by the manufacturer's warranty

The Reasonable Offset for Use (Usage Deduction)

The manufacturer may deduct a reasonable offset for the consumer's use of the vehicle before the problems reached the lemon law threshold. Iowa law provides a specific formula for this calculation:

Usage Offset = (Miles Driven x Purchase Price) / 120,000

The mileage used in this formula is measured up to the date of whichever event occurs first:

• The third repair attempt for the same nonconformity
• The first repair attempt for a defect likely to cause death or serious bodily injury
• The 20th cumulative day the vehicle is out of service for nonconformity repairs

For leased vehicles, the lessor's actual lease price is used in place of the purchase price, plus an additional amount equal to two percent of the purchase price.

Refund Distribution

The refund must be distributed to both the consumer and any lienholder (such as a bank or financing company) according to their respective interests.

How to File a Lemon Law Claim in Iowa

Step 1: Confirm Your Vehicle Qualifies

Before filing, verify that your vehicle meets these requirements:

• Purchased or leased as new in Iowa, or purchased or leased new in another state if you are an Iowa resident when you assert your rights
• Under two years old or under 24,000 miles from delivery
• Weighs less than 15,000 pounds gross vehicle weight
• Has a substantial nonconformity affecting use, value, or safety
• Has met the repair attempt or out-of-service threshold

Step 2: Document Every Repair

For each warranty repair, the manufacturer or authorized service agent must provide a fully itemized, legible repair order that includes:

• The diagnosis made
• All work performed on the vehicle
• A general description of the problem as reported by the consumer
• The date and odometer reading when the vehicle was brought in for repair
• The date when the repair was completed

Keep copies of every repair order. Also save receipts for towing, rental vehicles, and any other costs related to the defect.

Step 3: Send Written Notice to the Manufacturer

Send written notice to the manufacturer by certified or registered mail (or overnight delivery service) once you reach one of the notice triggers in Iowa Code Section 322G.4(1): three repair attempts for the same nonconformity, one repair attempt for a defect likely to cause death or serious bodily injury, or 20 or more cumulative days out of service for repairs.

Do not wait until 30 days out of service to send this notice. The 30-day figure is the presumption threshold in Section 322G.4(3), and under Section 322G.4(1)(b) you reach it by giving notice at 20 cumulative days and then allowing the manufacturer its 10 additional out-of-service days.

The Iowa Attorney General provides a Motor Vehicle Defect Notification form for this purpose. The notice must describe the nonconformity and give the manufacturer a final opportunity to repair the vehicle.

Step 4: Allow the Manufacturer a Final Repair Attempt

After receiving your written notice, the manufacturer has 10 days to notify you and provide the opportunity to bring the vehicle to a reasonably accessible repair facility. Once you deliver the vehicle, the manufacturer then has 10 additional days to conform the vehicle to the warranty.

If your notice was based on days out of service rather than repair attempts, Section 322G.4(1)(b) runs differently: starting on the date the manufacturer receives your notice, it has 10 more cumulative out-of-service days to conform the vehicle to the warranty.

Step 5: Pursue Arbitration or Legal Action

If the final repair attempt fails, you may pursue remedies through arbitration or court action (see below).

Manufacturer Disclosure Requirements at Purchase

Iowa law requires manufacturers to provide specific information to every consumer at the time of purchase or lease:

• A written statement prepared by the Iowa Attorney General explaining the consumer's rights and obligations under Chapter 322G
• The Attorney General's phone number for consumer inquiries
• The address and phone number of the manufacturer's zone, district, or regional office where claims can be filed

Failure to provide this information does not eliminate the consumer's rights but may affect procedural timelines.

Dispute Resolution Programs

Iowa law under Section 322G.6 requires manufacturers that have established certified informal dispute settlement programs to process consumer complaints through those programs.

Certified Arbitration Programs

Two major programs handle Iowa lemon law arbitration:

• BBB AUTO LINE: Free to vehicle owners of participating manufacturers; decisions are binding on the manufacturer if accepted by the consumer
• National Center for Dispute Settlement (NCDS): Handles claims for other participating manufacturers

Arbitration Timelines

Iowa law sets specific deadlines for the arbitration process:

What to Bring to an Arbitration Hearing

Prepare a well-organized presentation that includes:

• All repair orders and service records
• Your purchase or lease agreement
• A written timeline of all problems, repair dates, and days out of service
• Towing and rental car receipts
• Photos or videos of the defect
• Any correspondence with the manufacturer or dealer

Federal Magnuson-Moss Warranty Act

In addition to Iowa's state protections, the federal Magnuson-Moss Warranty Act (15 U.S.C. 2301) serves as a backstop for any consumer with an active written warranty, whether on a new or used vehicle. Under Magnuson-Moss, a manufacturer's breach of a written warranty is a federal claim that can be brought in federal court, with prevailing consumers entitled to attorney fees. Iowa lemon law and Magnuson-Moss claims can often be pursued together for the same defective vehicle.

Attorney Fees and Legal Remedies

Under Iowa Code Section 322G.8, a consumer who prevails in a lemon law court action is entitled to recover:

• The full amount of any pecuniary loss
• Reasonable attorney fees
• Court costs

This fee-shifting provision makes it financially feasible for consumers to hire an attorney, because the manufacturer bears the cost of the consumer's legal representation if the consumer wins.

Manufacturer Defenses

Iowa Code Section 322G.5 lists four affirmative defenses to a claim under Chapter 322G.

Timing is handled separately rather than as an enumerated defense: the presumption in Section 322G.4(3) reaches only repair attempts and out-of-service days that occur during the lemon law rights period.

To counter these defenses, keep thorough maintenance records showing you followed the manufacturer's recommended service schedule and did not modify the vehicle in ways that could cause the defect.

Title Branding and Resale Disclosure

Iowa law protects future buyers of vehicles that were returned under the lemon law. Under Iowa Code Section 322G.12 and Iowa Administrative Code Rule 61-30.3, anyone who sells, leases, or transfers a title to a lemon law buyback vehicle must provide a written disclosure to the buyer.

This disclosure must:

• Appear on a separate sheet of paper in at least 12-point type
• State in uppercase letters that the vehicle was returned under the Iowa Lemon Law or a similar law from another state
• Include the names and addresses of the seller and buyer
• Be signed and dated by both parties

The manufacturer must make a reasonable effort to ensure this disclosure is given to the first subsequent retail buyer or lessee. Failing to disclose constitutes an unfair or deceptive trade practice.

Used Vehicle Protections

Iowa's lemon law primarily covers new vehicles. However, several protections may apply to used vehicle purchasers.

Remaining Lemon Law Rights

If a used vehicle is still within its original lemon law rights period (under 2 years or 24,000 miles from first delivery), the new owner may have lemon law protection as a transferee, provided the terms of the warranty entitle that person to enforce it.

Federal Warranty Protections

The Magnuson-Moss Warranty Act (see above) provides federal protections for any vehicle buyer, new or used, who has an active manufacturer's or dealer's written warranty. This law allows consumers to sue for breach of warranty in federal court.

Iowa Consumer Fraud Act

Used vehicle buyers who are victims of fraudulent or deceptive sales practices may have remedies under Iowa's separate Consumer Fraud Act, regardless of warranty status.

Leased Vehicle Rights

Leased vehicles receive the same protections as purchased vehicles under Iowa's lemon law.

Lessee Remedies

If a leased vehicle qualifies as a lemon, the lessee may receive:

• A refund of all lease payments made
• Return of the security deposit
• Reimbursement of collateral charges (taxes, title, registration)
• Reimbursement of incidental costs (towing, rental vehicles)

Alternatively, if the consumer prefers, the manufacturer may provide a comparable replacement vehicle.

Lease Termination

When a leased vehicle is returned under the lemon law, the lease agreement terminates. The lessee owes no further payments beyond the reasonable usage offset.

Consumer Rights Cannot Be Waived

Under Iowa Code Section 322G.13, any agreement that waives, limits, or disclaims the rights provided under Chapter 322G is void as contrary to public policy. This means a manufacturer or dealer cannot require you to sign away your lemon law rights as a condition of purchase or as part of a settlement.

Dealer Liability Protections

Iowa's lemon law places obligations on manufacturers, not dealers. Under Iowa Code Section 322G.11, a manufacturer who improperly charges back a dealer because of a lemon law violation is liable to the dealer for full reimbursement, plus reasonable costs and attorney fees.

Statute of Limitations and Filing Deadlines

Understanding the deadlines for Iowa lemon law claims is essential to preserving your rights.

Frequently Asked Questions

How many repair attempts does Iowa require before a vehicle is considered a lemon?

Iowa law requires three or more repair attempts for the same nonconformity. For a serious safety defect likely to cause death or serious bodily injury, only one repair attempt is needed. Alternatively, if the vehicle is out of service for a cumulative total of 30 or more days for repairs of one or more substantial nonconformities, it may qualify. All conditions must occur within the lemon law rights period (manufacturer warranty term, 2 years, or 24,000 miles, whichever is shortest).

Do I need a lawyer to file an Iowa lemon law claim?

No. Iowa's lemon law is designed for consumers to pursue claims on their own through the manufacturer's certified dispute resolution program. The Iowa Attorney General provides forms and guidance. However, if your case is complex or you are unsatisfied with an arbitration outcome, hiring a private attorney may help. Under Iowa Code Section 322G.8, prevailing consumers can recover reasonable attorney fees from the manufacturer.

Does Iowa's lemon law cover used cars?

Iowa's lemon law primarily protects buyers of new vehicles. However, if you purchase a used vehicle that is still within its original lemon law rights period (under 2 years or 24,000 miles from original delivery), you may qualify as a transferee. The federal Magnuson-Moss Warranty Act also provides remedies for used vehicles with active warranties.

How is the usage deduction calculated in Iowa?

The reasonable offset for use is calculated as: (Miles Driven x Purchase Price) / 120,000. The mileage figure is measured up to whichever triggering event happens first: the third repair attempt for the same defect, the first repair for a defect likely to cause death or serious bodily injury, or the 20th cumulative day the vehicle is out of service. For leased vehicles, the lessor's actual lease price replaces the purchase price, plus two percent of the purchase price.

Does the consumer or the manufacturer choose between a refund and a replacement?

The consumer chooses. Iowa Code Section 322G.4 gives the consumer an unconditional right to elect a refund rather than a replacement vehicle. The manufacturer cannot force a replacement on a consumer who wants a buyback.

Are electric vehicles covered under Iowa's lemon law?

Yes. Iowa's lemon law covers any self-propelled motor vehicle under 15,000 pounds that is purchased or leased in Iowa, and (under Section 322G.15) vehicles bought or leased new in another state if you are an Iowa resident when you assert your rights. There is no personal-use requirement. This includes battery-electric vehicles, plug-in hybrids, and conventional hybrids. The statute does not exclude vehicles based on powertrain type. The exclusions apply only to motorcycles, autocycles, mopeds, motor homes, and vehicles over 15,000 pounds.
