Lemon-law presumption checklist · Iowa
Enter your repairs to check the presumption

This checklist is educational, not a legal verdict. Every state writes these numbers as a rebuttable presumption: hitting them shifts the burden to the manufacturer, and the manufacturer can still rebut it. Keep every repair order, send any required written notice, and consult a lawyer about your specific facts. This is legal information, not legal advice.

How the presumption works in Iowa

The prongs that shift the burden to the manufacturer.

Same-defect repair attempts
3 attempts on the same defect (presumption trigger)
Serious safety defect
1 attempt — statutory standard: likely to cause death or serious bodily injury
Days out of service
30 calendar days
What you must show
The defect must substantially impair the vehicle and be covered by warranty. Before the 3-attempt (or 1-attempt safety) presumption completes, you must send the manufacturer written notice by certified or registered mail or overnight service and allow one final repair attempt. Routine-maintenance downtime does not count toward the 30 days.

Iowa splits its counts: 3 attempts for an ordinary defect but only 1 attempt for a defect likely to cause death or serious bodily injury, each followed by a required written notice and a final repair attempt. A separate 20-day trigger lets you send that notice early, but the presumption itself runs on 30 cumulative days out of service.

These numbers are a presumption, not a hard gate

Every state, Iowa included, writes these thresholds as a rebuttable presumption. Reaching them shifts the burden onto the manufacturer to prove your vehicle is not a lemon; it does not mean you automatically win. You may also qualify with fewer attempts if a "reasonable number" of repairs is shown some other way, and the manufacturer can rebut the presumption. This is legal information, not legal advice.

Used cars & leased vehicles

Which of the three coverage categories Iowa falls in.

Category CNew vehicles only
Used cars
Iowa Code §322G.2 defines a consumer as the buyer or lessee of a new or previously untitled vehicle, so the lemon law reaches new cars only. There is no separate used-car lemon law in Iowa.
Leased vehicles
Covered. Iowa treats a lessee as a protected consumer.

What Iowa car buyers get wrong

Iowa runs its lemon law through the attorney general, and Chapter 322G has a two-step structure that trips up quick summaries. Under §322G.4, the state presumes a lemon after the same substantial defect has been examined or repaired 3 times, or just once for a defect "likely to cause death or serious bodily injury," and in each case only after you send written notice (certified, registered, or overnight) and give the manufacturer one final repair attempt. There is also a 30-cumulative-day out-of-service track, counted in calendar days and excluding routine-maintenance downtime. One number that confuses people: the statute lets you send your notice once the car has been out of service 20 days, but that is the early-notice trigger, not the presumption. The presumption itself is 30 days. As with every state, meeting these figures shifts the burden to the manufacturer rather than handing you an automatic win. The lemon law rights period is the earliest of warranty expiration, 2 years, or 24,000 miles, and coverage is limited to new or previously untitled vehicles.

Common questions

How many repair attempts is a lemon in Iowa?

Iowa presumes a lemon after 3 attempts on the same defect, or 1 attempt for a defect likely to cause death or serious bodily injury, each followed by written notice and a final repair attempt, or after 30 cumulative days out of service. These are presumption triggers that shift the burden to the manufacturer.

Does Iowa have a lower repair count for safety defects?

Yes. For a defect likely to cause death or serious bodily injury, a single repair attempt plus a final attempt after written notice can trigger the presumption, versus 3 attempts for an ordinary defect.

What is the difference between the 20-day and 30-day counts in Iowa?

The 20-day figure is only the point at which you may send the manufacturer written notice about out-of-service repairs. The presumption of a lemon runs on 30 cumulative calendar days out of service, excluding routine-maintenance downtime.

Does the Iowa lemon law cover used cars?

No. Chapter 322G covers a new or previously untitled vehicle only. Iowa has no separate used-car lemon law, so a car resold after being titled falls outside the statute.
