Arizona Lemon Law: How to File a Claim

Arizona's lemon law is A.R.S. §§ 44-1261–44-1266 (Motor Vehicle Warranties). It covers new vehicles; consumers include transferees during an applicable express warranty. Within the shorter of the warranty term or 2 years/24,000 miles: 4+ repairs of one nonconformity, or 30+ days out of service. After direct written notice: a qualifying dispute procedure, if one applies, then court.

The complete, plain-English walkthrough — built from A.R.S. §§ 44-1261 to 44-1267 and the Arizona Attorney General's auto-purchase guidance, not law-firm marketing. Last reviewed: October 2026.

Arizona lemon law at a glance

• The law: A.R.S. §§ 44-1261 to 44-1266 (Motor Vehicle Warranties). Used vehicles bought from dealers fall under a separate section, § 44-1267.
• Who is covered: the purchaser (other than for resale) or lessee of a motor vehicle, a person the vehicle is transferred to during an applicable express warranty, and anyone else entitled by the warranty's terms to enforce it.
• Report window: report the nonconformity during the shorter of the express warranty term or two years / 24,000 miles following original delivery, whichever is earlier. The Attorney General puts it the same way: coverage runs for the full length of the manufacturer's warranty or two years or 24,000 miles, whichever is earlier, beginning when the vehicle is given to the customer.
• The two tests: the same nonconformity repaired 4 or more times and still existing, or 30 or more cumulative calendar days out of service — both inside the report window. There is no separate safety-defect test.
• Written notice: the presumption applies only if the manufacturer received prior direct written notification of the defect and had an opportunity to cure it (§ 44-1264(C)).
• The hard deadline: begin an action within six months following the earlier of warranty expiration or the two-year / 24,000-mile point (§ 44-1265(B)).
• The remedy: replacement with a new motor vehicle, or return of the vehicle and a refund of the full purchase price, including all collateral charges, less a reasonable allowance for use — Arizona states no formula for that allowance.
• Fees: if you prevail in an action under the Act, the court shall award you reasonable costs and attorney fees (§ 44-1265(B)).
• Questions: Attorney General's Consumer Information and Complaints — Phoenix (602) 542-5763, Tucson (520) 628-6648, toll-free (800) 352-8431; complaints at azag.gov/consumer.

What vehicles are covered

Arizona's lemon law (A.R.S. §§ 44-1261 to 44-1266) covers a new motor vehicle — "a self-propelled vehicle designated primarily for the transportation of persons or property over the public highways." A "consumer" is the purchaser, other than for the purposes of resale, or lessee of a motor vehicle, any person to whom the motor vehicle is transferred during the duration of an express warranty applicable to it, or any other person entitled by the warranty's terms to enforce the warranty's obligations. The definition states no personal, family, or household-use requirement — its only use-related qualifier is the resale exclusion, plus the exclusions below.

You do not have to be the original owner. A later owner who receives the vehicle while an express warranty still applies is a consumer under the definition, and a lessee is named in the definition expressly.

• Motorcycles: not excluded. The definition contains no motorcycle exclusion and no engine-displacement threshold, and the Act states no motorcycle-specific tests or rules.
• Motor homes: the article applies to the self-propelled vehicle and chassis only — not to portions designed, used, or maintained primarily as a mobile dwelling, office, or commercial space. The Act states no motor-home-specific repair tests or offset divisor; the general tests and the no-formula use allowance apply.
• Not covered: a sale to a purchaser for the purpose of resale for profit; a vehicle with a declared gross weight over 10,000 pounds; and a vehicle sold at a public auction.

What counts as a defect. The manufacturer's duty is triggered by a defect or condition that substantially impairs the use and value of the motor vehicle to the consumer — Arizona's standard is "use and value," in the statute's own words. The Attorney General directs consumers to report problems that substantially limit the use and value of the vehicle and do not comply with the manufacturer's warranty, and to make that report during the covered period.

The two tests

The repair attempts and days are measured within the report window — the shorter of the express warranty term or the period of two years or 24,000 miles following the date of original delivery, whichever is earlier. It is presumed that a reasonable number of attempts have been made if either of these two tests is met:

1. Four-times test (same nonconformity)

The same nonconformity has been subject to repair 4 or more times by the manufacturer or its agents or authorized dealers within the window, but the nonconformity continues to exist. Different defects don't combine under this test.

2. 30-calendar-day test

The vehicle is out of service by reason of repair for a cumulative total of 30 or more calendar days within the window — calendar days, not business days. Days need not be consecutive.

No safety-defect shortcut. Unlike some states, Arizona's presumption has exactly these two prongs — there is no one-attempt test for a serious safety defect and no separate multiple-defects test. The Attorney General states the same pair: if the manufacturer fails to successfully repair the defect after four attempts, or the car is out of service for repairs for a total of 30 or more calendar days, the manufacturer must accept return of the car or replace it with a new car.

Extensions. The term of an express warranty, the two-year period, and the thirty-day period are extended by any period of time during which repair services are not available to the consumer because of war, invasion, strike, fire, flood, or other natural disaster (§ 44-1264(B)).

A report inside the window protects repairs after it. A nonconformity reported within the window must be repaired even if the repairs are made after the warranty term or the two-year / 24,000-mile limit expires (§ 44-1262(A)(2)). And § 44-1262 does not limit remedies available under a warranty that extends beyond the section's limits.

Step 1: the written notification to the manufacturer

Arizona's operative written step is built into the presumption itself. Under § 44-1264(C), the presumption does not apply against a manufacturer unless the manufacturer has received prior direct written notification from or on behalf of the consumer of the alleged defect and has had an opportunity to cure the alleged defect. In plain terms: write to the manufacturer directly, describe the defect, and give it the chance to fix the vehicle — before you rely on the four-attempts or 30-day tests.

The Act does not fix a number of days for that cure opportunity, a mailing method, or an address rule — so this guide prints none. What matters is that you can prove the notification happened: keep a dated copy of the letter and your delivery proof, whatever method you use. The LemonLawPath $29 packet includes a draft of this notification letter.

Keep the date of your first written report. Arizona measures the use allowance in a refund from your written reports: the allowance covers use before your first written report of the nonconformity to the manufacturer, its agent, or the dealer. A written record — not just a service-visit conversation — also feeds the repair log in the packet.

Step 2: the dispute procedure, then an action

Arizona's article creates no state-run arbitration program, no state filing form, and no filing fee. The route has two parts:

1. A manufacturer's own dispute procedure, if one applies. If a manufacturer has established or participates in an informal dispute settlement procedure that complies in all respects with the federal rule, 16 CFR Part 703, then § 44-1263's refund and replacement provisions do not apply to a consumer who has not first resorted to that procedure (§ 44-1265(A)). Check your warranty materials for whether your manufacturer has such a procedure. The Attorney General separately suggests that new-car owners consider filing a complaint with the BBB AUTO LINE Program or consulting an attorney — that is agency guidance, not a statutory requirement. Our manufacturer dispute programs guide explains how these programs work.
2. An action under the Act. If the vehicle still cannot be conformed, the endgame is an action under § 44-1265(B), begun within the six-month deadline below. The Act itself names no court; Arizona's Superior Court is the state's general jurisdiction court, with one or more locations in each county.

Optional background step: you can also file a consumer complaint with the Attorney General at azag.gov/consumer, or request a complaint form from the Consumer Information and Complaints contacts — Phoenix (602) 542-5763, Tucson (520) 628-6648, or (800) 352-8431 outside the Phoenix and Tucson metro areas. An AG complaint is not a step the Act requires, and filing one does not change the six-month deadline for an action.

The deadlines that matter

Two different clocks run under Arizona's law, and Arizona's filing tail is the shortest in our state set:

• Report window (for reporting the defect and for the repair tests): the shorter of the express warranty term or two years / 24,000 miles following original delivery, whichever comes first. Report the nonconformity inside this window — to the manufacturer, its agent, its authorized dealer, or the issuer of the warranty.
• Filing deadline: begin an action within six months following the earlier of the expiration of the express warranty term or two years or 24,000 miles following original delivery (§ 44-1265(B)).

One caution: nothing in the article pauses the six-month clock for time spent in a manufacturer's dispute procedure — even though using that procedure can be a precondition to the Act's remedies. If both clocks are anywhere near each other in your case, talk to a licensed Arizona attorney promptly rather than assuming time in a procedure protects the deadline.

Remedies: replacement or refund

If the manufacturer, its agents, or its authorized dealers are unable to conform the vehicle to an applicable express warranty after a reasonable number of attempts, § 44-1263(A) requires the manufacturer to replace the motor vehicle with a new motor vehicle or accept return of the vehicle and refund the full purchase price, including all collateral charges, less a reasonable allowance for the consumer's use. The section does not say who chooses between replacement and refund — it assigns the duty to the manufacturer and states no election, so this guide does not promise either side the choice.

• Refund: the full purchase price, including all collateral charges, less the use allowance. Refunds are made to the consumer and the lienholder, if any, as their interests appear. The Act uses the term "collateral charges" without defining or itemizing it anywhere in the article — so there is no statutory list of components to print here, and any breakdown beyond the tax rule below would be invented.
• Replacement: a new motor vehicle. The statute states no "identical or reasonably equivalent" standard — that is the whole of the stated duty.
• Tax on a return: if the manufacturer accepts return of the vehicle without replacing it, it shall refund the amount of tax attributed to the sale of the vehicle (taxes paid under Title 42, Chapter 5). If it replaces the vehicle with one of lesser value, it refunds the difference between the original tax and the tax on the replacement (excluding the replaced vehicle's value); on a replacement of greater value, it calculates gross proceeds under § 42-5001(6) (§ 44-1263(C)).
• The use allowance — no formula: Arizona sets no per-mile rate, divisor, or percentage. The reasonable allowance is the amount directly attributable to use by the consumer before his first written report of the nonconformity to the manufacturer, agent, or dealer, and during any subsequent period when the vehicle is not out of service by reason of repair. Because there is no formula, our worksheet and estimator show no calculated deduction for Arizona — they organize your first-written-report date and your out-of-service periods instead.
• Costs and attorney fees: if a consumer prevails in an action under the article, the court shall award the consumer reasonable costs and attorney fees (§ 44-1265(B)).

What the manufacturer may argue. It is an affirmative defense that an alleged nonconformity does not substantially impair the use and market value of the vehicle, or that the nonconformity results from abuse, neglect, or unauthorized modifications or alterations (§ 44-1263(B)). (Note the defense's wording — "use and market value" — differs slightly from the duty's "use and value.") Keep your records complete; they are the answer to both defenses.

After a buyback: the resale notification

Section 44-1266 is aimed at what happens next. A manufacturer that has been ordered by judgment or decree to replace or repurchase a vehicle, or that has replaced or repurchased one under this article or another state's repair-or-replace laws, must, before offering it for resale, attach written notification to the vehicle indicating it has been replaced or repurchased — and a consumer has a cause of action against a person who removes that notification. A dealer, broker, wholesale dealer, or wholesale auction dealer offering such a vehicle must give the purchaser the manufacturer's written notification before completion of the sale. This is background for buyers of repurchased vehicles, not a step in your own claim.

Used cars: a separate law

Bought used from a dealer? Arizona has a separate statute for you — § 44-1267, which the Attorney General calls the Arizona Used Car Lemon Law. It is a dealer-facing implied-warranty rule, not a smaller version of the new-car Act: a used motor vehicle dealer may not exclude, modify, or disclaim the implied warranty of merchantability (§ 47-2314), or limit the remedies for its breach, until the earlier of midnight of the fifteenth calendar day after delivery or 500 miles driven after delivery. On a breach, the purchaser gives the seller reasonable notice and a reasonable opportunity to repair, and pays one-half of the cost of the first two repairs, capped at $25 per repair; the seller's maximum liability is the purchase price.

Just as important is what § 44-1267 does not contain: no repair-attempt count that triggers a refund, no replacement right, no fee rule, and no filing deadline of its own — remedies run through Title 47, Chapter 2. Because there is no statutory refund-or-replacement process for a packet to operate, LemonLawPath offers no used-vehicle packet track for Arizona (unlike New Jersey and Massachusetts, whose used-car statutes do define one). The full walkthrough is in our Arizona used car lemon law guide.

When to talk to a lawyer instead

Arizona's process is built around a written notice, a possible dispute procedure, and then a court action on a short clock. Use LemonLawPath to get organized, then talk to a licensed lemon law attorney — especially if:

• Your defect is a serious safety hazard;
• The manufacturer denied your claim or disputes the defect;
• Your six-month deadline to begin an action is close, or may already have run;
• You are a lessee disputing how a refund would be computed — the Act names lessees as consumers but states no lease refund math;
• A manufacturer's dispute procedure is involved and you are unsure whether you must use it before the Act's remedies apply;
• Anything about your case feels ambiguous.
