How State Farm approaches these claims
State Farm's posture splits sharply along the Georgia line. IN GEORGIA: State Farm Mut. Auto. Ins. Co. v. Mabry, 274 Ga. 498, 556 S.E.2d 114 (Ga. Nov. 28, 2001) is a case against State Farm itself and is the single most claimant-favorable DV authority in the country. The Georgia Supreme Court held that a first-party collision policy's promise to pay for 'loss' covers diminution in value, reasoning that 'the fact of physical damage resulting from an event covered by the policy can reduce the value of a vehicle, even if repairs return it to pre-loss condition,' and that value, not condition, is the baseline for the measure of damages, the difference between the vehicle's value immediately before the collision and its market value immediately after being repaired. The Court affirmed a mandatory injunction requiring State Farm to evaluate ALL first-party claims for diminution in value without the policyholder having to make a separate claim, to develop an appropriate methodology (the evidence showed State Farm had none in use), to collect the information needed to determine the amount, and to report compliance to the court. So in Georgia a State Farm insured does not have to ask: if State Farm paid repairs and never assessed DV, that is itself a compliance problem. OUTSIDE GEORGIA: first-party DV is generally unavailable from State Farm because standard policy limit-of-liability language lets the insurer elect to repair; Mabry does not travel. Third-party DV, the not-at-fault claimant against State Farm as the at-fault driver's liability carrier, is paid where state tort law recognizes the measure, but the practical fight is over amount, not entitlement. State Farm publishes nothing about how it calculates DV: a full sweep of statefarm.com/claims, /claims/auto, /claims/resources/auto-claims and the claims FAQ found no mention of diminished value at all. LOWER CONFIDENCE: commercial DV appraisal firms and consumer legal sites widely report that State Farm anchors offers to a '17c'-style formula (a base loss capped at roughly 10% of pre-loss value, then reduced by damage-severity and mileage multipliers), and commonly attribute the name '17c' to paragraph 17(c) of the Mabry trial court order. That attribution is NOT verifiable in the Supreme Court's opinion, which expressly declined to impose any methodology and instead let State Farm develop its own; treat the 17c-origin story and the 10% cap as appraiser-sourced folklore, not established law or a published State Farm policy.
The Arizona rules that shape the claim
Farmers Ins. Co. of Arizona v. R.B.L. Inv. Co., 138 Ariz. 562, 564, 675 P.2d 1381, 1383 (Ct. App. 1983): compensation to the owner of a negligently damaged vehicle 'may include the cost of repair and proven residual diminution in fair market value.' Oliver v. Henry, 227 Ariz. 514, 516-17, 260 P.3d 314 (Ct. App. 2011): repair cost plus any before/after value difference plus loss of use, citing Restatement (Second) of Torts § 928.
A.R.S. § 12-542(3) sets two years for 'trespass for injury done to the estate or the property of another.' Arizona is one of the states where property damage and personal injury share the same two-year period - § 12-542 covers both in one statute, so there is no longer window for the vehicle claim. The clock starts on the date of the collision.

FAQ
State Farm in Arizona
Does State Farm pay diminished value claims in Arizona?
Arizona allows a not-at-fault driver to recover diminished value from the at-fault driver's liability insurer, and that applies to claims against State Farm. This carrier’s handling depends heavily on the state and on whether the claim is first-party or third-party. Your state page sets out which rules apply to you.
How long do I have to file against a State Farm driver in Arizona?
Arizona allows 2 years from the date of the accident for a vehicle property damage claim (Ariz. Rev. Stat. § 12-542(3)). The deadline is on filing suit, not on sending a demand letter, and negotiating with an adjuster takes weeks, so start well before it.
What if State Farm denies the diminished value claim?
Step 1: ask the assigned claim specialist IN WRITING for a written explanation of the denial or the exact calculation, the methodology used, the pre-loss value, the inputs and every deduction. A written request for a written calculation is the single most useful escalation move, because it forces a documented position and it is the record a regulator will read. Step 2: if the answer is a bare formula number or no answer, request escalation to the claim specialist's team manager and then the claim section manager, recording each name, title and date. Step 3: if you are a State Farm policyholder (any first-party claim, and every Georgia Mabry claim), bring in your local State Farm agent in writing, State Farm's captive-agent network is an internal escalation lever that a third-party claimant does not have, and the agent can push the claim file internally. Step 4: State Farm also handles complaints through the claim portal message thread at statefarm.com/claims/check-existing-claim, which third-party claimants can access by creating an account; use it so your complaint is inside the electronic claim file. Only after that go external: a state DOI market-conduct complaint, then small claims. In Georgia specifically, an unaddressed first-party DV claim is a Mabry compliance issue and belongs with the Office of the Commissioner of Insurance and Safety Fire, complaints at https://oci.georgia.gov/insurance-resources/complaints-fraud, consumer services (404) 656-2070 or (800) 656-2298. Beyond the carrier's own process, you can file a complaint with the Arizona Department of Insurance and Financial Institutions (DIFI), and Arizona's small claims court hears claims up to $5,000, which covers most vehicle diminished value amounts.
