Iowa's Lemon Law, found at Iowa Code Chapter 322G, presumes a new vehicle is a "lemon" if the manufacturer or its dealer has made three or more attempts to fix the same substantial defect, or if the vehicle has been out of service for a cumulative total of 30 or more calendar days for warranty repairs. These attempts must happen during the "lemon law rights period," which Iowa defines as the time ending two years after the original delivery date of the vehicle or the first 24,000 miles of operation, whichever comes first. If your vehicle meets this test and the defect substantially impairs its use, value, or safety, the manufacturer must give you a comparable replacement vehicle or a refund. These are concrete Iowa-specific thresholds, so do not assume the rules from a neighboring state apply here.
Which vehicles and defects qualify under Iowa law
The Iowa Lemon Law applies to new motor vehicles that were purchased or leased in Iowa and are still within the lemon law rights period. The law is generally aimed at vehicles used primarily for personal, family, or household purposes, though it can extend to certain vehicles used in a small business. Several categories are typically excluded, including motorcycles, mopeds, and the living-facilities portion of motor homes (the chassis and drivetrain of a motor home may still be covered). Vehicles above a certain gross weight rating may also fall outside the law. Because these exclusions can be technical, confirm your specific vehicle type against the statute or with the Iowa Attorney General's office before assuming you are or are not covered.
A qualifying defect is a "nonconformity" -- a defect or condition that substantially impairs the use, market value, or safety of the vehicle and is covered by the manufacturer's express written warranty. Minor cosmetic issues, problems caused by owner abuse, neglect, accidents, or unauthorized modifications generally do not qualify. The defect must be one the manufacturer was given a fair chance to repair.
The repair-attempt and days-out-of-service triggers
Iowa law creates a legal presumption that the manufacturer has had a "reasonable number of attempts" to repair the vehicle when either of the following occurs within the lemon law rights period:
The same nonconformity has been subject to repair three or more times by the manufacturer or its authorized dealer, and the defect continues to exist; or
The vehicle has been out of service because of warranty repairs (for one or more nonconformities) for a cumulative total of 30 or more calendar days.
Iowa also recognizes a stricter standard for the most dangerous defects. If a nonconformity is one that is likely to cause death or serious bodily injury if the vehicle is driven, a smaller number of repair attempts can trigger the law. Because the exact safety-defect threshold and its definitions are specific, verify the current language of Iowa Code 322G.4 if you believe a serious safety defect applies to your situation.
Importantly, at least one repair attempt must have occurred during the warranty period, and you must report the defect to the manufacturer, its agent, or its authorized dealer during the lemon law rights period. Keep every repair order, including the date you brought the vehicle in, the dates it was returned, and a written description of the problem reported each time. These documents are the backbone of any Iowa lemon law claim.
How to get a refund or replacement vehicle
Once the presumption is met and the manufacturer cannot conform the vehicle to the warranty after a reasonable number of attempts, Iowa law requires the manufacturer -- at your choice as the consumer -- to either:
Replace the vehicle with a comparable new motor vehicle acceptable to you; or
Refund the full purchase or lease price, including collateral charges (such as sales tax, license and registration fees, and similar government charges) and reasonable incidental costs, less a reasonable allowance for your use of the vehicle.
The "reasonable offset for use" is a deduction the manufacturer is allowed to take based on the miles you drove the vehicle before it was first brought in for the defect. Iowa calculates this using a statutory mileage formula tied to the vehicle's purchase price, so the offset grows with the miles driven. If your vehicle is financed, the refund must be distributed appropriately between you and the lienholder so that any loan is paid off.

Manufacturer dispute-resolution programs and arbitration
Many manufacturers operate an informal dispute settlement procedure (an arbitration program). Under Iowa law, if a manufacturer has established such a program and it complies with applicable federal and state requirements, you generally must first submit your dispute to that program before you can pursue certain remedies in court. These programs are usually free to consumers and must render a decision within a set period. If you are dissatisfied with the arbitrator's decision, you typically retain the right to file a lawsuit; an arbitration decision under these programs is generally not binding on the consumer.
If you do go to court and prevail, Iowa's Lemon Law allows a successful consumer to recover reasonable attorney fees and court costs. This fee-shifting provision is significant because it makes it realistic to hire an attorney even when the dollar amount in dispute would otherwise make litigation impractical.
Deadlines and how Iowa compares to federal law
Pay close attention to timing. The core protections of the Iowa Lemon Law are tied to the lemon law rights period (two years or 24,000 miles, whichever is first), and there is a separate, limited window in which you must actually file any lawsuit. Because the exact statute-of-limitations language can be technical, do not rely on memory -- confirm the current filing deadline in Iowa Code Chapter 322G or with an attorney before your window closes. Missing a deadline can permanently bar an otherwise strong claim.
Iowa's Lemon Law works alongside the federal Magnuson-Moss Warranty Act, the national law governing written and implied warranties on consumer products, including vehicles. Magnuson-Moss also allows a prevailing consumer to recover attorney fees and can apply to used vehicles and situations the state lemon law does not reach. Many vehicle warranty cases are brought under both the Iowa statute and Magnuson-Moss at the same time to maximize the available remedies.
How to enforce your rights and where to verify the law
To protect yourself, take these practical steps:
Report each defect promptly and in writing to an authorized dealer, and make sure it is documented on the repair order every visit.
Save all paperwork -- purchase and finance contracts, the warranty booklet, every repair order, and any correspondence with the manufacturer.
Notify the manufacturer directly (not just the dealer) in writing once the problem persists, and keep proof of mailing.
Use the manufacturer's arbitration program if one exists, then consult an attorney if you are not satisfied.
To verify the current rules, deadlines, and any updates to Chapter 322G, contact the Iowa Attorney General's Office, Consumer Protection Division. That office enforces Iowa's consumer-protection laws, publishes consumer guidance, and can tell you how the Lemon Law applies to your facts. For binding legal advice on your specific vehicle, consult a licensed Iowa attorney who handles warranty and lemon law cases.

Frequently asked questions
How many repair attempts does Iowa require before a vehicle is a lemon?
Under Iowa Code Chapter 322G, the law presumes a reasonable number of attempts has been made when the same substantial defect has been subject to repair three or more times, or when the vehicle has been out of service for warranty repairs for a cumulative total of 30 or more calendar days, all within the lemon law rights period. A serious safety defect likely to cause death or injury can trigger the law after fewer attempts.
How long do I have to invoke Iowa's Lemon Law?
Iowa's protections apply during the "lemon law rights period," which ends two years after the vehicle's original delivery date or at the first 24,000 miles, whichever comes first. You must report the defect during that period, and at least one repair attempt must occur within the warranty. A separate, shorter window applies to actually filing a lawsuit, so confirm the current deadline before acting.
Can I choose a refund instead of a replacement vehicle in Iowa?
Yes. When a vehicle qualifies, Iowa law gives the consumer the choice between a comparable replacement vehicle or a refund of the purchase or lease price plus collateral charges, minus a reasonable allowance for the miles you drove before the defect was first reported. If you have a loan, the refund is allocated to pay off the lienholder.
Does Iowa's Lemon Law cover used cars, motorcycles, or motor homes?
The Iowa Lemon Law primarily covers new motor vehicles purchased or leased in the state. Motorcycles, mopeds, and the living-facilities portion of motor homes are generally excluded, though a motor home's chassis and drivetrain may be covered. Used vehicles usually fall outside the state law, but the federal Magnuson-Moss Warranty Act may still protect you if a written warranty applies.
Do I have to use the manufacturer's arbitration before suing in Iowa?
If the manufacturer has established a qualifying informal dispute settlement (arbitration) program, you generally must submit your dispute to it first before pursuing certain remedies. The arbitrator's decision is typically not binding on you as the consumer, so if you are dissatisfied you can usually still file suit, where prevailing consumers may recover attorney fees and costs.
