KEY TAKEAWAYS
Arizona lets drivers who weren’t at fault recover the drop in their vehicle’s market value from the at-fault driver’s insurer, even after a full repair and even if they never sell the car. Adjusters rarely raise diminished value on their own, and the formulas insurers use tend to shrink it, so an independent appraisal is usually the strongest evidence. The Flagstaff injury team at Griffen & Stevens treats the property damage check as the first piece of a crash claim, not the end of it, because a release signed to get the car fixed can affect everything that comes after.
The body shop did good work. The paint matches, the panels line up, and your SUV drives the way it did before someone ran the light on Route 66. Then you check its trade-in value and learn it’s worth thousands less than it was the morning of the crash. A vehicle history report now shows a collision, and buyers pay less for cars that have one. That gap is the basis of a diminished value claim, and in Arizona, the driver who caused the crash can be made to pay it.
At Griffen & Stevens, our Flagstaff car accident attorneys often hear about diminished value from people who are already frustrated with an adjuster. They have a repaired car, a closed property damage file, and a nagging sense that something was left off the table. Usually, they’re right.
What Is a Diminished Value Claim?
A diminished value claim asks the at-fault driver’s insurer to pay for the loss in your vehicle’s market value caused by the crash, on top of the cost of repairs. Appraisers and insurers generally sort that loss into three categories, and the one that applies shapes how the claim is valued.
Inherent Diminished Value
This is the most common type. Even a flawless repair can’t erase an accident from a vehicle history report, and a car with a reported crash sells for less than an identical car without one. Inherent diminished value measures that stigma.
Repair-Related Diminished Value
When repairs fall short (mismatched paint, uneven panel gaps, or aftermarket parts in place of factory parts), the car loses more value than the accident history alone would explain. These claims often overlap with a dispute over whether the repair was done right in the first place.
Immediate Diminished Value
This is the drop in value between the moment before the crash and the moment after, before any repairs. It matters most when a car is sold in its damaged condition.
Can You Get Diminished Value From the Other Driver’s Insurance in Arizona?
Yes. In Oliver v. Henry, a 2011 decision, the Arizona Court of Appeals held that the owner of a negligently damaged vehicle can recover the cost of repairs plus any remaining loss in market value. The owner doesn’t have to sell or trade in the car to prove that loss, and an expert appraisal can establish it. In that case, the at-fault driver’s insurer had already paid more than $15,000 to repair a Jeep Wrangler, and the owner was still awarded $8,975 for the value the Jeep had lost.
There are limits. Diminished value is a claim against the driver who caused the crash, which in practice means that driver’s liability insurer. Most collision policies don’t pay diminished value when you file with your own insurer, so read your policy before assuming otherwise. And if you share some blame for the crash, your recovery is reduced by your percentage of fault.
How Much Is a Diminished Value Claim Worth in Arizona?
There is no fixed percentage. The value depends on facts specific to your vehicle, including:
- The car’s pre-crash market value, since newer and higher-value vehicles lose more in dollar terms
- Mileage and overall condition before the crash
- How severe the damage was, especially frame damage, structural repairs, or airbag deployment
- Whether the shop used factory parts and followed manufacturer repair standards
- How the crash shows up on vehicle history reports
Why the Insurer’s Number Is Usually Low
Many insurers calculate diminished value with a formula commonly called “17c.” It starts by capping the loss at 10 percent of the car’s pre-accident value, then cuts that figure with multipliers for damage severity and mileage. A higher-mileage vehicle with moderate damage can come out of that formula close to zero, even when a dealer would knock thousands off its trade-in price. The formula traces back to a Georgia insurance case, not to any Arizona statute or court ruling, and you aren’t required to accept it.
What Makes a Stronger Claim
The evidence that carried the day in Oliver was an independent appraisal. A written report from a qualified diminished value appraiser, supported by comparable sales, gives you a number grounded in the actual market rather than in the insurer’s math. Dealer trade-in quotes can help too. Keep your repair invoices, photos of the damage, and a copy of the vehicle history report.
Why the Adjuster Won’t Bring Up Diminished Value
Property damage adjusters work from a familiar list: repair estimate, rental car, towing, and maybe a total-loss valuation. Diminished value usually isn’t on it. A claimant who never asks is a claimant who never gets paid for it, and the adjuster has little reason to volunteer an extra line item.
When drivers do ask, the pushback tends to sound the same. The car was “restored to pre-loss condition.” Diminished value “isn’t paid in Arizona.” The claim can only be considered after a sale. Oliver answers all three. If an adjuster is pressing you for a quick sign-off, our FAQ on whether to talk to an insurance adjuster after a car crash covers what to say and what to hold back.
Policy Limits and Deadlines Can Shrink the Claim
Arizona’s minimum property damage liability coverage is just $15,000 per accident, according to the Arizona Department of Transportation. Repairs, the rental car, towing, and diminished value all come out of that same pool. On a newer truck or SUV, a minimum-limits policy can run dry before the diminished value claim is paid, leaving the at-fault driver personally responsible for the rest.
Timing matters too. Arizona generally allows two years from the crash to file a lawsuit for damage to property, the same window that applies to most injury claims under the state’s personal injury statute of limitations. Insurers know that deadline as well as anyone.
Don’t Let the Car Claim Close Out an Injury Claim
Here is the part that catches people off guard. Property damage often settles within weeks, while injuries can take months to fully reveal themselves. Before you sign a property damage release, read it closely. It should be limited to vehicle damage and should not release claims for bodily injury, medical bills, or lost wages. A broad release signed just to get the car back on the road can wipe out a far larger claim, which is one reason to be wary of a quick settlement after a car accident.
If you were hurt, the diminished value check is a small piece of what may be owed. Medical expenses, lost income, and pain and suffering all belong in the same conversation, and our guide to the damages you may collect after an Arizona car crash breaks down each category.
