The Ultimate Diminished Value Guide for Idaho

When a vehicle is involved in an accident, the financial impact may extend beyond the cost of repairs. Even after high quality repairs are completed, a vehicle may still lose market value simply because it now has an accident history.

This reduction in resale value is commonly known as diminished value.

In Idaho, drivers who are not at fault for a collision may recover diminished value as part of a property damage claim filed against the at-fault driver's insurer. Idaho Code Section 5-218 gives drivers three years from the date of the accident to file this type of claim.

What Is Diminished Value?

Diminished value refers to the difference between a vehicle’s value before an accident and its value after repairs are completed.

Even when repairs restore the vehicle to safe operating condition, the accident history often remains visible through vehicle history reports such as CARFAX or AutoCheck. Because many buyers prefer vehicles without accident history, the presence of a prior collision can reduce resale value.

For many vehicles, this difference in value represents a real financial loss after an accident.

Can You File a Diminished Value Claim in Idaho?

In most cases, Idaho drivers pursue diminished value as a third-party property damage claim, filed and negotiated directly with the at-fault driver's insurance company.

First-party diminished value claims against your own insurer are less common in Idaho and are typically limited to policies that specifically include this coverage. A qualifying claim usually requires completed repairs, an accident report, and evidence that the vehicle's resale value has dropped as a result.

Because diminished value reflects market perception, the amount of loss can vary depending on several factors including:

• vehicle age

• mileage

• severity of damage

• structural repairs

• prior accident history

• local vehicle market conditions

How Insurance Companies Evaluate Diminished Value

Idaho insurers most often rely on a formula-based approach, such as the widely used 17c method, which applies a capped percentage to the vehicle's pre-accident value regardless of the actual market impact. Other insurers instead review comparable vehicle listings and regional market data.

Because these approaches can produce very different results, and formula-based estimates often understate the real loss, an independent appraisal built on direct market comparison tends to hold up better during negotiation and, if needed, dispute.

How Diminished Value Is Documented

Diminished value is commonly evaluated using a market comparison approach that analyzes similar vehicles with and without accident history.

This type of evaluation may include:

• comparable vehicle listings

• vehicle history disclosures

• repair documentation

• regional vehicle market data

By comparing similar vehicles, an appraisal can help estimate the difference between the vehicle’s pre accident value and its post repair market value.

Diminished Value Claims in Major Idaho Cities

Vehicle accidents happen throughout Idaho's metro areas and highway corridors every year. Drivers in Boise, Nampa, and Idaho Falls may face diminished value after a collision even when repairs are completed correctly, and the three-year filing window under Idaho Code 5-218 applies statewide regardless of city.

Because accident history becomes part of a vehicle's permanent record through CARFAX and AutoCheck, buyers across Idaho's used vehicle market, from Boise to Idaho Falls, may value a repaired vehicle differently than one with a clean history.
