State lemon law · checked October 23, 2026
Verified against the statute / official state publicationUtah Code §§13-20-1–13-20-8 (New Motor Vehicle Warranties Act)
| Presumption window | The window is the earlier of the warranty term or 1 year after delivery. |
|---|---|
| Same defect | 4+ repair attempts |
| Days out of service | 30+ business days — 30 or more BUSINESS days out of service. |
The presumption is the set of numbers that shifts the burden to the manufacturer. A claim can exist outside the presumption — it is a shortcut, not the whole road. Read why.
Utah allows a reasonable allowance for use with no statutory formula. (Practitioners often see roughly 10–23 cents per mile argued — a negotiation range, not a rule. This checker prints no invented number.)
No statutory notice letter gates the Utah presumption (for a recreational-vehicle trailer, notification is required). Written notice remains the record that wins cases.
Dispute route: You must use the manufacturer's informal dispute settlement or arbitration procedure, if one exists, before the statutory remedy.
Attorney's fees: Utah makes manufacturers pay the consumer's attorney's fees in a successful claim.
Utah's Act prints no specific filing deadline (the general UCC period is commonly assumed). The warranty/1-year presumption window is the operative clock.
