Arizona Lemon Law Statute: Notice, Refund, and Deadlines

Arizona’s lemon law, found at A.R.S. §§ 44-1261 through 44-1267, requires a manufacturer to replace your new vehicle or refund your money when a substantial defect cannot be fixed after a reasonable number of repair attempts.¹ The statute presumes you have given the manufacturer enough chances once the same defect has gone through four repair attempts, or the vehicle has sat in the shop for 30 or more cumulative days, during the coverage period.²

Which Vehicles the Law Covers

The statute protects new motor vehicles, meaning self-propelled vehicles designed primarily to transport people or property on public highways.³ A “consumer” is the original purchaser (other than someone buying for resale), anyone the vehicle is transferred to during the express warranty period, or anyone else entitled to enforce the warranty under its terms. The statute does not limit coverage to vehicles bought for personal or household use, so a small business owner who buys a new truck for commercial purposes can qualify.

Motorhomes are only partly covered. The self-propelled vehicle and chassis fall under the law, but the portions designed as living quarters, office space, or commercial space do not.³ A failing engine, transmission, or drivetrain is within the statute. A broken refrigerator or jammed slide-out is not.

How Long You Have to Report a Defect

You must report the nonconformity to the manufacturer, its agent, or an authorized dealer within the shorter of two periods: the term of the manufacturer’s express warranty, or two years from the date the vehicle was first delivered to you or 24,000 miles on the odometer, whichever comes first.⁴ If your express warranty runs only 12 months or 12,000 miles, that shorter period controls, even though the statute’s outer limit is longer.

Both the two-year window and the 30-day out-of-service clock can be extended if repair services become unavailable because of war, strikes, fire, floods, or other natural disasters.²

What Counts as a Lemon

Your vehicle qualifies when it has a defect or condition that substantially impairs its use and value to you, and the manufacturer has not fixed it after a reasonable number of attempts.¹ The law makes “reasonable” concrete by creating a presumption once either threshold is met during the coverage period:

The same nonconformity has been subject to repair four or more times, and it still exists.
The vehicle has been out of service for repairs for a cumulative total of 30 or more calendar days.

Those 30 days do not need to be consecutive.² Five days now, eight days a month later, and so on, all count toward the total. Every repair order should show the day the vehicle entered the shop and the day you got it back, so the days can be counted precisely.

The Written Notice You Have to Send

The presumption only applies after the manufacturer has received direct written notification from you (or someone acting on your behalf) describing the defect, and has been given an opportunity to cure it.² The statute does not require certified mail, but certified mail with a return receipt gives you proof the manufacturer received the notice and when, which matters in arbitration or litigation.

A useful notice identifies the vehicle by VIN, describes the defect in plain terms, summarizes the repair history (dates, mileage, work performed), and states that you are demanding a replacement or refund. The manufacturer’s address is usually in the owner’s manual or warranty booklet. Keep copies of everything.

Manufacturer Arbitration You May Have to Use First

If the manufacturer has an informal dispute settlement procedure that complies with federal regulations at 16 CFR Part 703, you must use it before you can demand a replacement or refund under § 44-1263.⁵ Many manufacturers run these programs through BBB AUTO LINE or similar providers. An unfavorable decision does not end your rights; you can still sue. But skipping a qualifying program entirely hands the manufacturer a defense.

Refund or Replacement

When the manufacturer cannot fix the vehicle after a reasonable number of attempts, it must either replace it with a comparable new vehicle or accept the return and refund the full purchase price plus all collateral charges, such as taxes, registration fees, and dealer documentation fees paid at the time of sale.¹

Deduction for Your Use

The manufacturer can subtract a reasonable allowance for your use of the vehicle. The statute defines that allowance as the amount attributable to your use before you first reported the nonconformity in writing to the manufacturer, its agent, or dealer, plus any time after that when the vehicle was not in the shop for repairs.¹ The earlier you put the complaint in writing, the smaller the deduction. If you drove 1,500 miles before your first written report, the deduction covers those 1,500 miles. If you waited until 15,000, it covers all of them.

If You Still Owe on the Loan

If you financed the vehicle, the manufacturer must make the refund payments to you and the lienholder as their interests appear.¹ The remaining loan balance goes directly to the lender. After the buyback closes, ask the lender for written confirmation that the account shows a zero balance; a lingering open balance can trigger late-payment reporting if the payoff takes weeks to post.

What the Manufacturer Can Argue Back

The statute gives the manufacturer two affirmative defenses. It can argue that the alleged nonconformity does not substantially impair the use and market value of the vehicle, or it can argue that the problem resulted from abuse, neglect, or unauthorized modifications or alterations you made.¹

The first defense is where most fights happen. A persistent but minor rattle, a cosmetic flaw, or an intermittent infotainment glitch may annoy you without meeting the “substantially impairs” standard. The second defense is why aftermarket modifications on a vehicle you suspect is a lemon are a bad idea. Even if the modification had nothing to do with the defect, the manufacturer will argue the link and you will have to disprove it.

Deadline to File Suit and Who Pays the Lawyer

A lemon law lawsuit must be filed within six months after the earlier of the express warranty’s expiration or two years (or 24,000 miles) from original delivery, whichever comes first.⁵ That window is tight, especially if you spent months in manufacturer arbitration first. Calendar it the moment you start the process.

If you win, the court must award you reasonable costs and attorney fees.⁵ This fee-shifting is what makes most lemon law cases economically viable. Many lemon law attorneys take cases on contingency, expecting the manufacturer to pay their fees if the claim succeeds.

Documentation That Makes or Breaks the Claim

Start collecting records the first time you notice a problem, not after the fourth repair attempt. The pieces you need:

Repair orders and invoices showing the VIN, the mileage at drop-off, the dates in and out of the shop, and specific descriptions of the complaint and the work done. If the service advisor writes something vague like “customer states vehicle makes noise,” ask for a more precise entry.
A communication log with dates and summaries of every call, email, or conversation with the dealer’s service department and the manufacturer’s customer line, along with the name of each person you spoke with.
A copy of your written notice to the manufacturer, with the certified mail receipt and return receipt card showing delivery.

Mileage at each visit matters for two separate calculations: whether you remain within the 24,000-mile coverage window, and how the use allowance is computed when a refund is paid. A visit with no written repair order, or an order missing the mileage, is the kind of ambiguity manufacturers use against you.

The Federal Backup: Magnuson-Moss

Arizona’s statute is not your only option. The federal Magnuson-Moss Warranty Act lets consumers damaged by a warrantor’s failure to honor a written or implied warranty sue in state or federal court, and a prevailing consumer can recover costs and reasonable attorney fees.⁶ If you miss Arizona’s six-month filing deadline or the defect first surfaces just past the state coverage period, a federal claim may still be open under the longer federal limitations period.

To bring a Magnuson-Moss claim in federal court the amount in controversy must be at least $50,000 (excluding interest and costs) if claims are combined, or at least $25 for an individual claim; state court filings do not require those thresholds.⁶ As with the Arizona statute, if the manufacturer has an informal dispute resolution procedure that complies with 16 CFR Part 703, you may need to use it before filing suit.⁷
