Consumer Definition
A "consumer" under Iowa law is the purchaser or lessee (other than for resale or sublease) of a new motor vehicle primarily used for personal, family, or household purposes. This includes any person to whom the vehicle is transferred during the warranty period who uses it for the same purposes.
Iowa's Lemon Law Presumption
Iowa law creates a "lemon law rights period" and establishes when a vehicle is presumed to be defective. The rights period is the shortest of:
- The term of the manufacturer's written warranty
- Two years after original delivery
- The first 24,000 miles of operation
The Lemon Law Presumption Applies When:
| Condition | Requirement | Time/Mileage Limit |
|---|---|---|
| Repair Attempts (Same Problem) | 3 or more attempts | Within rights period |
| Serious Safety Defect | 1 or more attempts | Defect likely to cause death or serious bodily injury |
| Days Out of Service | 20 or more days (cumulative) | Within rights period |
| Nonconformity Type | Substantially impairs use, value, or safety | Or significantly diminishes value |
What Qualifies as a Nonconformity?
A "nonconformity" under Iowa law is a defect, malfunction, or condition that fails to conform to the manufacturer's express warranty and:
- Substantially impairs the use or market value of the motor vehicle, or
- Renders the vehicle unfit, unreliable, or unsafe for ordinary use
Examples of Covered Defects
- Engine or transmission failures
- Brake system malfunctions
- Steering problems
- Electrical system failures
- Fuel system defects
- Air conditioning/heating failures
- Safety equipment malfunctions
- Persistent warning lights for major systems
Consumer Remedies: Refund vs. Replacement
When a vehicle qualifies as a lemon under Iowa law, the consumer can receive either a full refund or a replacement vehicle.
Option 1: Vehicle Refund (Buyback)
If the consumer receives a refund, the manufacturer must pay:
- Purchase price: Full cash price paid for the vehicle
- Trade-in value: Allowance given for any trade-in vehicle
- Collateral costs: Sales tax, license fees, registration fees, and similar charges
- Finance charges: Interest and finance fees paid
- Incidental costs: Towing and rental expenses incurred due to the defect
Usage Deduction: The manufacturer may deduct a reasonable allowance for the consumer's use of the vehicle, calculated based on miles driven.
Option 2: Replacement Vehicle
The consumer may receive a replacement vehicle that is:
- Comparable to the original vehicle
- Acceptable to the consumer
- Covered by manufacturer's warranty
Refund Distribution
Refunds must be made to the consumer and any lienholder (such as a financing company) as their interests appear.

Manufacturer Defenses
Manufacturers may raise several defenses to avoid lemon law liability in Iowa.
Common Manufacturer Defenses

Used Vehicle Protections
Iowa's lemon law is primarily designed for new vehicles. However, some protections exist for used vehicle buyers.
Remaining Lemon Law Rights Period
If you purchase a used vehicle that is still within the original lemon law rights period (2 years/24,000 miles from first delivery), you may have lemon law protection as a transferee.

Iowa Consumer Fraud Act
Used vehicle buyers may have remedies under Iowa's Consumer Fraud Act for fraudulent or deceptive sales practices.

Iowa's lemon law applies to leased vehicles as well as purchased vehicles.
Leased Vehicle Remedies
If a leased vehicle qualifies as a lemon:
- All lease payments made may be refunded
- Security deposits returned
- Collateral costs reimbursed
- Or a comparable replacement vehicle provided
Usage Deduction for Leases
A reasonable allowance for use may be deducted from amounts returned to the lessee.
Lease Termination
When a leased vehicle is returned under the lemon law, the lease agreement terminates without further obligation to the consumer beyond any usage deduction.
Statute of Limitations
Understanding the deadlines for filing a lemon law claim is critical for Iowa consumers.
