Even before Hurricane Isaias reached landfall as the first Atlantic hurricane of the year, there were already potentially 48,000 vehicles sustaining flood damage in the U.S. from storms in 2026, according to Carfax estimates.

Those vehicles add to a vehicle population that already included more than 500,000 water-damaged vehicles currently on U.S. roads, the company said.

Spring and summer storms affected thousands of vehicles in states like Michigan, Wisconsin, Mississippi, Indiana and West Virginia, but impacted vehicles can often end up in used-car markets away from where the damage occurred, Carfax said, citing law enforcement.

“Floodwater can leave behind damage that isn’t always obvious when a vehicle is cleaned up and put back on the market. And those cars can appear far from the area where the storm occurred,” Carfax chief product officer Paul Nadjarian said in a news release. “With storms bringing flooding across the country, it’s a good reminder for anyone shopping for a used car to understand its reported history.

“A vehicle may look great on the outside while hidden water damage can create serious problems. Consumers can search millions of new and used vehicles on CARFAX Car Listings, where every listing includes a free CARFAX Report.”

The company listed the states with the most water-damaged vehicles on the road.

Those include:

  1. Florida 75,000
  2. Texas 67,100
  3. Kentucky 31,600
  4. California 25,200
  5. Pennsylvania 23,600
  6. North Carolina 19,700
  7. New Jersey 18,300
  8. South Carolina 16,100
  9. New York 14,900
  10. Tennessee 14,100
