There is a folk version of the lemon law that circulates in every state, and it goes roughly like this: if a new car goes into the shop three times for the same thing, you get your money back. It is close enough to the truth to be dangerous, because the details that vary between states are the details that decide cases — and in Utah, the detail most likely to cost somebody their claim is not the number of repairs at all. It is the calendar.
Utah's version lives at Title 13, Chapter 20 of the Utah Code. The chapter heading calls it the New Motor Vehicle Warranties Act. Section 13-20-1, its own short title, calls it the "New Motor Vehicles Warranties Act," with vehicles plural. That small inconsistency between the heading and the text has been sitting there since the chapter was enacted in 1985, and it is a useful reminder that this is a document to read rather than to remember.
The clock is one year, not the length of your warranty
Start here, because everything else is downstream of it.
Section 13-20-3 says that if a new motor vehicle does not conform to all applicable express warranties, and the consumer reports the nonconformity to the manufacturer, its agent or its authorized dealer during the term of the express warranties or during the one-year period following the date of original delivery of the motor vehicle to a consumer, whichever is earlier, then the manufacturer, agent or authorized dealer shall make the repairs necessary to conform the vehicle.
Read those five words again: whichever is earlier. Modern factory warranties routinely run three years or thirty-six thousand miles, sometimes far longer on the powertrain. None of that extends this chapter. For a vehicle sold with any warranty longer than twelve months — which is essentially all of them — the operative window under Utah's lemon law is one year from original delivery.
This is the single most common way a Utah claim dies, and it dies quietly. The owner is not being negligent. They are being reasonable: the car is under warranty, the dealer keeps agreeing to look at it, nobody is refusing anything, and the assumption that there is time is the assumption the statute punishes.
One thing does survive the deadline. Once the nonconformity has been reported inside the window, the repair obligation continues "whether or not these repairs are made after the expiration of the warranty term or the one-year period." The clock governs the reporting, not the fixing.
What counts as a reasonable number of attempts
Section 13-20-4 is where the remedy lives, and it is triggered when the manufacturer, its agent or its authorized dealer is unable to conform the vehicle to an express warranty after a reasonable number of attempts, in respect of a defect or condition that substantially impairs the use, market value, or safety of the vehicle.
Section 13-20-5 then tells you when a reasonable number of attempts is presumed. There are two triggers and they are independent:
- The same nonconformity has been subject to repair four or more times by the manufacturer, its agent or its authorized dealer within the express warranty term or the one-year period, whichever is earlier, and the nonconformity continues to exist; or
- The vehicle has been out of service to the consumer because of repair for a cumulative total of 30 or more business days during the warranty term or the one-year period, whichever is earlier.
Two features of that are worth pulling out.
The first trigger requires the same nonconformity. Four visits for four unrelated faults do not add up under this prong. This is why the wording on the repair order matters so much: a service department that writes up the same underlying fault three different ways has, on paper, created three different problems.
The second trigger does not care about the cause at all. Thirty cumulative business days out of service is thirty days, whether that was one long wait for a part or eight short visits. For a vehicle with an unavailable component, this is frequently the prong that fires first.
Both periods are extended by any time during which repair services were unavailable to the consumer because of war, invasion, strike, fire, flood or other natural disaster.
Note the word presumed. Falling short of four repairs or thirty days does not automatically defeat a claim; it means the consumer no longer has the presumption doing the work for them.
What you get, and what gets deducted
If the threshold is met, Section 13-20-4(1) requires the manufacturer to either replace the vehicle with a comparable new motor vehicle, or accept return of the vehicle and refund the full purchase price including all collateral charges — in each case less a reasonable allowance for the consumer's use. Refunds go to the consumer and to any lienholders or lessors as their interests appear, and on receipt the consumer, lienholder or lessor furnishes clear title and possession back to the manufacturer.
The use allowance is defined at Section 13-20-4(2), and the definition is more favorable than most people expect. It is the amount directly attributable to use by the consumer prior to the consumer's first report of the nonconformity, plus use during any subsequent period when the vehicle was not out of service because of repair.
The consequence is worth stating plainly: the months your car spent in a service bay are not deducted from your refund, and neither, on the face of the text, is the use that came after you first reported the problem. That makes the date of first report a load-bearing fact twice over — it starts the repair obligation and it caps the deduction.
The two defenses
Section 13-20-4(4) gives the manufacturer two affirmative defenses, and they are the whole battleground in a contested case:
- that the alleged nonconformity does not substantially impair the consumer's use of the vehicle and does not substantially impair its market value or safety; or
- that the alleged nonconformity is the result of abuse, neglect, or unauthorized modifications or alterations by a consumer.
The first is why a persistent rattle and a persistent brake fault are treated differently, and why documenting the practical effect of a fault — not just its existence — is the most useful thing an owner can do. The second is why aftermarket modification history tends to surface early.
You cannot go straight to court
Two procedural gates sit in front of the remedy, and both are easy to miss because neither is where you would look for them.
The Division of Consumer Protection. Section 13-20-6(1) provides that the Division shall, or a consumer may, enforce the rights created under the chapter — and then states that an action may be commenced by a consumer only after the claim has been investigated and evaluated by the division. That is a precondition to suit written into the enforcement section.
The manufacturer's own dispute program. Section 13-20-7 provides that if a manufacturer has established an informal dispute settlement procedure complying with 16 C.F.R. Part 703 — the Federal Trade Commission's rule on informal dispute settlement mechanisms under the Magnuson-Moss Warranty Act — then Section 13-20-4, the refund-and-replacement section, does not apply to a consumer who has not first resorted to that procedure. Many manufacturers do operate such a program. Whether a given manufacturer's program actually complies with Part 703 is itself a question, and not one to resolve by reading the manufacturer's brochure.
There is one piece of good news attached to the litigation route. Section 13-20-6(4) provides that in an action initiated by the consumer, the court may award attorneys' fees to the prevailing party. Read that carefully too — it says prevailing party, not prevailing consumer, so it cuts both ways.
Leased vehicles are inside the chapter
A widespread assumption is that the lemon law is for people who bought a car, and that a lease is a rental problem to be taken up with the leasing company. The definition says otherwise.
Section 13-20-2(1) defines a consumer as an individual who enters into an agreement or contract for the transfer, lease, purchase of a new motor vehicle other than for purposes of resale, or sublease during the duration of the period defined under Section 13-20-5. Four routes into the chapter, and two of them are leasing.
The remedy provisions were drafted with that in mind. Section 13-20-4(1) directs that refunds be made to the consumer and any lienholders or lessors as their interests may appear, and Section 13-20-4(3) requires that on receipt of a refund or replacement, the consumer, lienholder or lessor furnish clear title and possession to the manufacturer. The statute contemplates from the outset that the person driving the vehicle and the person holding the paper on it may be different, and it does not make that a reason to deny the driver a remedy.
The practical warning for a lessee is the same one that applies to a buyer, only sharper. The one-year clock runs from the date of original delivery of the vehicle to a consumer. A lease term of thirty-six or forty-eight months creates a strong intuition that there is time. There is not.
Which vehicles are in, and which are out
Section 13-20-2(4) defines motor vehicle by inclusion and then by a long exclusion list. The definitions were amended by Chapter 334 of the 2026 General Session, so this is one of the fresher parts of the chapter.
In: a motor home, but only the self-propelled vehicle and chassis sold in this state; a motor vehicle as defined in Section 41-1a-102 sold in this state; and a motorcycle as defined in that section, if designed primarily for use and operation on paved highways.
Out: the portions of a motor home designated, used or maintained primarily as a mobile dwelling, office or commercial space; road tractors and truck tractors; mobile homes; any motor vehicle with a gross laden weight over 14,000 pounds, except a motor home and a farm tractor; motorcycles designed primarily for use over unimproved terrain; electric assisted bicycles; mopeds; and motor assisted scooters.
The motor home split is the one that catches people. Buy a motor home with a chronic chassis fault and you are inside the chapter. Buy the same motor home with a chronic fault in the living quarters and you are not.
Travel trailers get mediation instead
A recreational vehicle trailer — a travel trailer, camping trailer or fifth wheel trailer, per Section 13-20-2(5) — does not get the refund-or-replacement remedy at all. Section 13-20-8 routes it to mandatory mediation, and the conditions are cumulative:
- the owner notifies the manufacturer in writing of the nonconformity;
- the nonconformity is manifest in the structural or functional integrity of the roof, subfloor, or wall;
- following that notice, the manufacturer makes at least four attempts to correct it and the nonconformity persists;
- the owner then submits a written request for mediation;
- the nonconformity substantially impairs the use, value or safety of the trailer; and
- the nonconformity is not the result of business or commercial use, or of abuse, neglect, modification or alteration by someone other than the manufacturer or its authorized service agent.
Mediation takes place in the county where the owner purchased the trailer, is conducted by the Consumer Arbitration Program for Recreation Vehicles, and the manufacturer pays the cost. Failure of the mediation does not impair any other right or remedy the owner has under the law.
Given how much of the recreational vehicle market moves through Utah Valley, the roof-subfloor-wall limitation deserves emphasis. A trailer with a chronic appliance or electrical fault does not meet the Section 13-20-8 conditions, however maddening it is.
This chapter is not your only remedy
One sentence at the end of the enforcement section is easy to skim and worth holding onto. Section 13-20-6(3) provides that the chapter does not limit the rights or remedies which are otherwise available to a consumer under any other law.
That matters most for the people this chapter excludes. A used-car buyer, an owner of a vehicle over the weight limit, a motor home owner whose fault is in the living quarters, a trailer owner whose problem is not the roof, subfloor or wall — none of them has a claim under Title 13, Chapter 20, and none of them is therefore without options. Express and implied warranty law, the federal Magnuson-Moss Warranty Act, and Utah's general consumer sales practices provisions all sit outside this chapter and are unaffected by it.
The reverse is also worth knowing. Missing the one-year reporting window closes this door specifically. It does not close every door, and a claim that is too late for the lemon law may still be timely somewhere else.
What to do if you think you have one
Report the fault the day you notice it, in writing. The first report date sets the repair obligation and caps the use deduction. A text message or an email to the service department creates a date that a phone call does not.
Read the repair order before you leave. You are checking that the written description matches the fault you actually reported, and that it matches the description on the previous visits for the same problem. If the write-up drifts, ask for it to be corrected on the spot.
Keep every repair order, including the ones where nothing was found. A visit where the technician could not reproduce the fault is still a repair attempt for the same nonconformity, and it is still a day out of service.
Count days out of service separately from visits. The thirty-business-day trigger runs on its own and is frequently reached first.
Diarize the delivery date. Not the purchase date, not the finance date — the date of original delivery. That is the date the one-year period runs from.
Contact the Division of Consumer Protection before contacting a lawyer about filing. It is a statutory precondition, not a formality, and it is free.
