Auto loan defaults are climbing, and the timing could not be worse for lenders. Used car prices, which surged to historic highs during the supply chain chaos of 2021 and 2022, have been falling steadily – and the gap between what borrowers owe and what their cars are actually worth is turning into a serious problem for the consumer credit market.
A Market Built on Inflated Collateral
When used car prices spiked, dealers and lenders operated in an environment where a three-year-old sedan could sell for more than its original sticker price. Lenders extended loans against those inflated valuations, often financing 100% or more of a vehicle’s purchase price. Borrowers, many of whom were stretching budgets already thinned by broader inflation, took on monthly payments sized for a market that no longer exists.
The correction has been significant. Used vehicle wholesale prices have been falling for several consecutive quarters, erasing much of the pandemic-era premium. A borrower who financed a used truck at peak pricing in 2022 may now find their vehicle worth thousands less than the remaining loan balance. That gap – known as being “underwater” or having negative equity – eliminates the borrower’s ability to sell the car and pay off the debt cleanly if they hit financial trouble.
Subprime auto loans are absorbing the most pressure. Lenders who extended credit to borrowers with lower credit scores during the boom years did so against collateral that looked strong at the time. Now, with repossession values declining alongside the broader used car market, those lenders face a double hit: elevated default rates and weaker recoveries when they take the vehicle back and sell it at auction.
Repossession auction lanes, which function as a real-time price signal for used car values, have been showing softer numbers for months. When a lender repossesses a vehicle and sells it wholesale, any shortfall between the auction price and the outstanding loan balance becomes a direct loss. Those losses are compounding across portfolios, particularly at finance companies and credit unions that leaned heavily into used car lending during the boom.
Why the Pain Is Spreading Beyond Subprime
The default story started in subprime, but the stress is now moving up the credit spectrum. Even borrowers with solid credit scores are defaulting at rates that are higher than pre-2020 baselines. The reason is straightforward: the cost of owning a car has increased across every line item. Insurance premiums have risen sharply. Maintenance costs are up. Fuel expenses remain elevated in many regions. A borrower who qualified comfortably on paper two years ago may now be watching too much of their paycheck disappear into a single vehicle.
Loan terms also got longer during the boom, which makes the math worse. A 72- or 84-month loan stretches out the period of negative equity, meaning borrowers are underwater for longer. If a job loss, medical bill, or other financial shock hits during that window, there is no easy exit. The car cannot be sold to cover the debt, and rolling the negative equity into a new loan – a common workaround in more stable markets – requires finding a lender willing to take on that risk, which is increasingly rare.
Lenders have responded by tightening standards, but the tightening is happening after the portfolios are already booked. The loans sitting on balance sheets right now reflect the underwriting decisions of 2021 and 2022, when competition for loan volume was fierce and price optimism was running high. Tighter standards today do not fix yesterday’s approvals.
There is a geographic dimension to the pressure as well. Markets where vehicle ownership is not optional – sprawling metros without transit, rural areas, Sun Belt suburbs built entirely around car culture – see borrowers hold on longer before defaulting because losing the car means losing access to work. That behavior can mask early stress in delinquency data, making the eventual default spike look sudden when it has actually been building for months.
The broader consumer credit picture adds context. Credit card delinquencies have been rising alongside auto loan stress, suggesting that many households are managing cash flow across multiple debt obligations simultaneously. When something has to give, auto loans sometimes get prioritized over credit cards because the vehicle is essential – but that calculation eventually breaks down when the total debt load becomes unmanageable.
What Lenders and Borrowers Are Doing Now
Some lenders are quietly expanding loan modification programs, extending terms or reducing payment amounts for borrowers who ask before they default. The logic is practical: a modified loan in good standing is worth more than a repossession sold into a weak auction market. Forbearance, which became a standard tool during the pandemic, is again being offered in limited form by select lenders as an alternative to triggering default on collateral that will not recover its value at auction.
For borrowers, the calculus is harder. Trading in a car with negative equity is expensive, refinancing requires qualifying in a tighter credit environment, and simply continuing to pay means funding a vehicle worth less than the debt attached to it. The option that many borrowers resist – voluntary surrender – at least stops the bleeding on monthly payments, but it does not erase the deficiency balance, which the lender can still pursue. That deficiency exposure is keeping some borrowers current on payments they can barely afford, trapped in loans tied to assets whose value keeps sliding.
