Quick Answer: Yes — Arizona’s lemon law (A.R.S. § 44-1261 through 44-1267) entitles you to a full refund or replacement vehicle if your new car has a defect that substantially impairs its use, value, or safety and the manufacturer cannot fix it after a reasonable number of repair attempts. To qualify, the defect must appear within two years or 24,000 miles of delivery, and you must give the manufacturer a final written repair opportunity before filing a claim. Arizona’s lemon law covers new vehicles only — used cars are not covered unless sold with a manufacturer’s warranty still in effect.
Does Arizona Have a Lemon Law?
Yes. Arizona’s New Motor Vehicle Warranties Act (A.R.S. §§ 44-1261 through 44-1267) requires manufacturers — not dealers — to either replace your vehicle or refund your purchase price when a covered defect cannot be repaired within a reasonable number of attempts during the coverage period.
One thing that trips people up: your dealer may have been the one doing the repairs, but your lemon law claim is against the vehicle manufacturer, not the dealership. Arizona also requires manufacturers to participate in a state-certified arbitration program, and you’ll need to go through that process before you can file a civil lawsuit.
What Vehicles Qualify Under Arizona Lemon Law
To be covered, your vehicle needs to check all of these boxes:
Vehicle type: It must be a new motor vehicle — a passenger car, pickup truck, van, or SUV — sold or leased in Arizona primarily for personal, family, or household use. Motorcycles and vehicles over 10,000 lbs. GVW are excluded.
Warranty coverage: The vehicle must be covered by the manufacturer’s original express warranty.
Time and mileage window: The defect must first occur within two years or 24,000 miles of the original delivery date — whichever comes first.
Purchased or leased in Arizona: The vehicle must have been originally purchased or leased from a licensed Arizona dealer.
What Defects Qualify
Not every mechanical problem gives you lemon law rights. The defect has to substantially impair the use, market value, or safety of the vehicle.
Defects that typically qualify include engine or transmission failures that prevent normal operation, brake system problems that create a safety risk, electrical failures affecting how the car drives, persistent stalling or a vehicle that won’t start, steering or suspension defects affecting control, and safety system failures involving airbags or seatbelts.
What won’t qualify: damage caused by the owner — accidents, misuse, or unauthorized modifications — minor cosmetic issues that don’t affect use or value, and problems resulting from alterations made after delivery.
The “substantially impairs” standard depends on the specific facts. If the same defect keeps coming back and affects how you’re able to use the car or raises a genuine safety concern, it generally meets the bar.
The Repair Attempt Requirement
Arizona law presumes that a reasonable number of repair attempts has been exceeded — and that your lemon law rights kick in — in either of two situations:
Standard defects: The same defect has been subject to repair four or more times within the two-year/24,000-mile window and still isn’t fixed.
Safety defects: The defect is one that could cause death or serious bodily injury, it has been subject to repair at least twice within the coverage window, and it still exists.
Out-of-service rule: If your vehicle has been out of service for a cumulative total of 30 or more calendar days within the coverage period, the presumption also applies — regardless of how many separate repair attempts there were.
Keep records of every repair visit: date in, date out, mileage, the complaint you described, work performed, and parts replaced. Your dealer repair orders are your primary evidence, so hold onto all of them.
The Final Written Repair Opportunity
Before filing an Arizona lemon law claim, you have to give the manufacturer one final chance to fix the problem — in writing.
Send a letter by certified mail, return receipt requested, to the manufacturer’s customer service address (you’ll find it in your owner’s manual or warranty booklet). The letter should clearly state the specific defect, that prior repair attempts have not fixed it, that you are demanding a final repair opportunity under A.R.S. § 44-1264, and your contact information along with the vehicle’s VIN, year, make, model, and current mileage.
The manufacturer then has 10 days to respond and make the vehicle available for repair. If the defect still isn’t corrected after that final attempt, you can move forward with your claim.
Don’t skip this step. Failing to provide written notice is a procedural bar to a lemon law claim in Arizona — it can stop your case before it starts.
Refund vs. Replacement: What You Can Claim
If your vehicle qualifies, you choose between two remedies.
Full Refund (Buyback)
The manufacturer repurchases your vehicle and refunds the full purchase price, including collateral charges like sales tax, registration fees, and finance charges, plus any incidental costs directly caused by the defect. The manufacturer is allowed to deduct a “reasonable allowance for use” based on the mileage you put on the car before the first repair attempt for the defect. The formula is: (mileage at first repair attempt ÷ 100,000) × purchase price.
If you financed the vehicle, the manufacturer pays off the outstanding loan balance as part of the buyback. Whatever is left after the loan payoff goes back to you.
Replacement Vehicle
The manufacturer provides a comparable new vehicle — same make, model, and equipment — at no charge. If an identical replacement isn’t available, a comparable substitute is provided. The same use deduction may apply here as well.
Which Is Better?
Most people who’ve had serious problems with their vehicle go for the refund rather than a replacement from the same manufacturer. If you do want a replacement, make sure you get the specifics of what “comparable” means in writing before agreeing to anything.
How to File an Arizona Lemon Law Claim
Arizona law requires you to go through a state-certified arbitration program before filing a civil lawsuit. Most major manufacturers operate programs that have been certified by the Arizona Attorney General’s office.
Step 1: Confirm you meet the requirements. Review the repair attempt threshold, coverage window, and written notice requirement. Make sure your documentation is complete.
Step 2: Identify the manufacturer’s arbitration program. Your owner’s manual or warranty booklet lists the manufacturer’s dispute resolution program. Many use BBB Auto Line; others run their own. Call the manufacturer’s customer service line and ask specifically about their Arizona-certified arbitration program.
Step 3: File your arbitration claim. Submit your claim with complete vehicle information (VIN, year, make, model, purchase date, mileage), all repair orders from every service visit, a copy of your written final repair notice and proof of delivery, documentation of any out-of-pocket costs caused by the defect, and your requested remedy — refund or replacement.
Step 4: Arbitration hearing. You’ll be scheduled for a hearing, typically by phone or in writing, though in-person hearings are available. Present your repair records, explain how the defect has affected your ability to use the vehicle, and state what remedy you’re seeking.
Step 5: If arbitration fails. If the decision goes against you or the manufacturer doesn’t comply with an arbitration award, you can file a civil lawsuit in Arizona Superior Court. A successful civil action can result in recovery of the refund or replacement, plus reasonable attorney’s fees and costs.
The BBB Auto Line Arbitration Program
BBB Auto Line is the most commonly used manufacturer dispute resolution program in Arizona. It covers claims against manufacturers including Ford, GM, Stellantis, Toyota, Honda, Subaru, Nissan, and others.
You can reach BBB Auto Line at bbb.org/auto-line or by phone at 1-800-955-5100. Filing is available online or by phone at no charge to consumers.
The process is set up to be accessible without an attorney. From filing to decision typically takes around 40 days. If the arbitrator rules in your favor, the manufacturer has 30 days to comply. If they don’t, you can use that award as evidence in a civil lawsuit.
Arizona Lemon Law and Used Cars
Arizona’s lemon law does not cover used vehicles purchased without an unexpired manufacturer’s warranty. If the original warranty has fully run out, the lemon law simply doesn’t apply — no matter how many problems the vehicle has.
There are a couple of situations where used car coverage may come into play. If you buy a used vehicle and the original manufacturer’s warranty still has time left — say you purchase a one-year-old car with three years remaining on a four-year powertrain warranty — defects covered under that remaining warranty may still trigger lemon law protections. Similarly, Certified Pre-Owned vehicles come with manufacturer-backed warranties that generally function like original warranties for lemon law purposes. If your CPO vehicle develops a covered defect during the CPO warranty period and meets the repair attempt threshold, Arizona’s lemon law may apply. It’s worth talking to a consumer protection attorney to evaluate your specific CPO warranty terms.
If a used car was sold to you with concealed defects or outright misrepresentation, you may have separate legal remedies under Arizona’s consumer fraud law (A.R.S. § 44-1521 et seq.) and federal law — even when the lemon law itself doesn’t apply. These are separate legal paths and worth evaluating with an attorney.
Frequently Asked Questions
Does Arizona lemon law cover leased vehicles? Yes. Arizona’s lemon law covers vehicles obtained through retail lease agreements, as long as the other requirements are met — covered vehicle type, defect within the coverage period, and sufficient repair attempts. The remedy for a leased vehicle may look a little different; typically the lease is terminated and lease payments are refunded rather than a purchase price buyback.
What if my manufacturer doesn’t have a certified arbitration program in Arizona? Arizona law requires manufacturers to participate in a state-certified arbitration program. If one doesn’t exist for your manufacturer, you can go straight to civil court without going through arbitration first. The Arizona Attorney General’s Office Motor Vehicle Division can verify the status of any manufacturer’s program.
How long do I have to file an Arizona lemon law claim? The defect must first appear within two years or 24,000 miles of original delivery. Once you meet the repair attempt threshold, the statute doesn’t set a hard deadline to file your arbitration claim — but the sooner you act, the better. Waiting too long can complicate your evidence and limit your options. If significant time has passed since the coverage period ended, talk to an attorney.
Do I need a lawyer for an Arizona lemon law claim? Not necessarily for the arbitration stage — BBB Auto Line and other certified programs are designed to be accessible for consumers representing themselves. That said, if arbitration doesn’t go your way and you end up in civil court, or if the manufacturer is pushing back hard, having a consumer protection attorney in your corner can make a meaningful difference in what you recover. You can search for consumer attorneys through naca.net.
What if the dealer sold me the car with known defects? Dealer fraud and lemon law are separate claims. The lemon law runs against the manufacturer. If a dealer knowingly concealed defects, misrepresented the vehicle’s condition, or committed fraud in the sale, that’s a distinct claim under Arizona consumer fraud statutes (A.R.S. § 44-1521) and potentially federal law. Both claims can be pursued at the same time.
Can I get my attorney’s fees paid if I win? Yes. If you prevail in a civil lemon law action in Arizona Superior Court after going through arbitration, the court may award reasonable attorney’s fees and costs. This fee-shifting provision is one reason civil lemon law cases can be worth pursuing even when the dollar amount of the dispute feels modest.
What is the mileage deduction formula for an Arizona lemon law buyback? Arizona uses this formula: (mileage at first repair attempt ÷ 100,000) × original purchase price. For example, if the defect first appeared at 8,000 miles and you paid $35,000 for the vehicle, the deduction would be (8,000 ÷ 100,000) × $35,000 = $2,800. Your refund would be $35,000 minus $2,800, or $32,200, plus collateral charges.
