How Liberty Mutual approaches these claims
Liberty Mutual routinely resists third-party DV demands. In a documented May 2026 case a not-at-fault North Carolina driver whose nearly new car was rear-ended was denied repeatedly for over a year; the company would not engage with her appraiser's $5,675 report and paid that full amount only after a TV consumer reporter contacted it. Appraisers also report it anchors offers to a 17c-style formula rather than market comparables. Outcomes vary by state law more than company policy: DV is recoverable from the at-fault carrier in most states, is barred or limited first-party in states like Florida and Texas, and Georgia's Mabry rule requires DV evaluation even first-party.
The Idaho rules that shape the claim
No reported Idaho appellate decision squarely on automotive diminished value. Idaho's general personal-property damages rule, the difference between value immediately before and immediately after the loss, together with reasonable repair costs, supplies the theory. Cite that general measure rather than a DV-specific holding.
Three years for 'taking, detaining or injuring any goods or chattels,' which covers vehicle damage. Longer than Idaho's two-year personal-injury SOL under Idaho Code § 5-219(4), a common and costly confusion. Accrual generally runs from when the owner knew or should have known of the damage.

A first refusal is a position. Answer it in writing; then the Idaho Department of Insurance complaint route and small claims court (up to $15,000) are both open, inexpensive, and documented.
FAQ
Liberty Mutual in Idaho
Does Liberty Mutual pay diminished value claims in Idaho?
Idaho allows a not-at-fault driver to recover diminished value from the at-fault driver's liability insurer, and that applies to claims against Liberty Mutual. This carrier has a documented pattern of resisting diminished value claims. Put everything in writing, keep the certified mail receipts, and plan for escalation from the start.
How long do I have to file against a Liberty Mutual driver in Idaho?
Idaho allows 3 years from the date of the accident for a vehicle property damage claim (Idaho Code § 5-218(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 Liberty Mutual denies the diminished value claim?
Get a written denial with reasons from the assigned claims representative, then ask in writing for escalation to their supervisor and then the claims manager, recording names and dates. Liberty Mutual publishes no dedicated DV appeals unit; the general claims line is 800-225-2546 and documents can be filed at secureupload.libertymutual.com. The appraisal clause sits in the Liberty Mutual policyholder's contract, so a third-party claimant normally cannot invoke it. Once internal escalation stalls, the realistic routes are a state DOI complaint and small claims court against the at-fault driver. Beyond the carrier's own process, you can file a complaint with the Idaho Department of Insurance, and Idaho's small claims court hears claims up to $15,000, which covers most vehicle diminished value amounts.
