Iowa Auto Repair Law

Educational summary only – not legal advice.

If you get your car repaired in Iowa and the repair is expected to cost more than $50, you have the legal right to receive an estimate before work begins if you ask for one. You may choose a written estimate, oral estimate, or decline an estimate, but the shop must clearly document your choice before starting repairs.

Once an estimate is provided, a repair shop cannot charge more than 10% over that estimate without first getting your approval. If unexpected issues arise, the shop must contact you and receive authorization before performing additional work or adding charges.

You are protected from being billed for repairs that were not authorized, not completed, or unnecessary. If a shop violates these rules, you may file a complaint with the Iowa Attorney General’s Consumer Protection Division, and unlawful charges may be voided.

Iowa law does not automatically require shops to return replaced parts to you. You may request them, but the statute itself is silent; general consumer protection law applies.

What this means for repair shops

If you operate an auto repair shop in Iowa, you must comply with the Motor Vehicle Service Trade Practices Act. For any job expected to exceed $50, you must inform customers of their right to an estimate and document whether they want a written estimate, oral estimate, or no estimate.

Written authorization forms must include required disclosures such as the customer’s contact information, the shop’s name, the date, and an anticipated completion date. Repairs may not begin until authorization is obtained.

If you provide an estimate, it becomes binding. You may not exceed the estimate by more than 10% unless you obtain the customer’s prior approval for the additional cost. Failure to do so can result in refunds, voided charges, or enforcement action.

All estimate and authorization records must be retained at your place of business for at least nine (9) months.

Iowa law does not specify automatic parts-return rules or storage-fee limits; however, deceptive or unfair practices remain enforceable under general consumer protection statutes.
