Stop First-Party Fraud Before the Car Leaves the Lot

Auto lending has the highest first-party fraud rate of any industry SentiLink measures. We reconstructed 25 missing-car cases from public court records and scored them. Most showed elevated risk at application, when the lender could still act.

• 5.31% of auto applications showed first-party fraud risk in 1H 2026, more than twice the cross-industry average
• 0.73% of funded auto loans flagged high risk in private studies, tied to almost 14% of documented losses
• 762 median First Party Fraud Score for the 25 missing-car cases, vs. 95 for the benchmark

Auto lending draws this fraud because the payoff is a portable, resalable asset. In SentiLink's analysis of 170 million applications in 1H 2026, auto was the only industry where first-party fraud outpaced identity theft (4.51%).

Why do identity checks and underwriting miss first-party fraud in auto lending?

Identity checks and underwriting miss first-party fraud because the applicant is who they say they are. When the loan defaults, it's often booked as an ordinary credit loss. The warning signs sit outside any single lender's records: a burst of applications at other institutions, a new phone number, an address with little history. Each looks ordinary on its own.
