How to check if a car was flood damaged
After hurricanes and floods, water-damaged cars are cleaned up and sold, sometimes hundreds of miles away. A VIN check catches the ones an insurer or a state recorded. Your nose, your eyes and a mechanic catch more.

Why flood damage matters
A flooded car can look fine on a test drive. NHTSA says flood damage can affect a vehicle’s mechanisms for years and may not cause problems right away. NMVTIS notes that saltwater flooding makes electrical systems, including airbag sensors, more prone to failure.
Flooded cars also travel. After Hurricane Katrina, NMVTIS says, truckloads of flooded vehicles were taken from Louisiana to other states as far as the upper Midwest, dried out and sold in states that do not brand flood vehicles. The FTC and NHTSA both warn that storm-damaged cars are often taken out of state for sale.
Check the VIN first
NICB VINCheck (free). Enter the 17-character VIN to see whether participating insurers have reported the car as flood-damaged, salvage, or stolen and not recovered. It only finds cars that were insured when they were damaged, and it allows five searches per IP address per 24 hours.
NMVTIS report (low fee). It shows any flood, salvage or junk brand a state has applied, with the date, plus insurer total-loss records. Because NMVTIS keeps every reported brand, moving a car to a state with no flood brand does not erase it from the record. Approved providers are listed on the official site.
Fuller history report (paid). The FTC says reports from other providers can add accident and repair history. A car flooded without an insurance claim may still have no record anywhere, so a clean report is where the checking starts, not where it ends.

Signs of flood damage to look for
| Check | What to look for |
|---|---|
| Smell | A musty or moldy smell, or a heavy smell of air freshener or cleaning products covering it up, in the cabin or the trunk. |
| Mud, sand and waterlines | Silt or dried mud under the seats, carpet, floor mats and dashboard, and in hidden spots such as the trunk and glove box. |
| Carpet and upholstery | Carpet that is loose, stained or mismatched, or new carpet or upholstery in an older car. |
| Lights | Fogging or moisture inside the headlights and taillights. |
| Rust and corrosion | Rust around the doors, and more rust or corrosion under the car than its age and location explain. |
From the FTC and NHTSA flood-car checklists. Look in daylight, and pull back a corner of the carpet and the trunk floor if the seller lets you.
Get it inspected
Pay an independent mechanic to look for water damage before you buy. The FTC notes that water can slowly destroy mechanical and electrical systems and cause rust and corrosion, and that a history report is not a substitute for an inspection. If a dealer will not let you have the car inspected, the FTC suggests going to another dealer.
Flood damage is one of several things a history report can miss. Our accident history guide and used car checklist by VIN cover the rest.
Report a hidden flood car
If you think a dealer is knowingly selling a storm-damaged or salvaged car as one in good condition, the FTC says to contact NICB (online or at 800-TEL-NICB, 800-835-6422), report it at ReportFraud.ftc.gov, and tell your state attorney general.
FAQ
Can I check if a car was in a flood by VIN for free?
Yes, partly. NICB VINCheck is free and shows flood, salvage and theft records reported by participating insurers. The FTC points out it only has the car if it was insured when it was damaged. An NMVTIS report, sold for a fee by approved providers, shows a flood brand if a state applied one.
Does a clean title mean the car was never flooded?
No. Some states have no flood brand, flooded cars are often moved to other states for sale, and a car whose owner had no insurance claim may have no record at all. NHTSA warns buyers to beware of flood-damaged cars with clean or “lost” titles.
What is a flood title?
A title brand some states apply to cars damaged by water. The FTC describes it as damage from sitting in water deep enough to fill the engine compartment. Brand names and rules vary by state, and NMVTIS keeps every brand reported by any state.
Is it legal to sell a flood-damaged car?
NHTSA says a totaled car can be legally resold to consumers when the damage is noted on the title, the car has been rebuilt and it has a rebuilt title. Selling a storm-damaged car as one in good condition is what the FTC asks buyers to report.
Are flooded electric and hybrid cars dangerous?
They can be. NHTSA says their batteries are highly corrosive and should not sit in standing water, and that flooded vehicles may have high voltage and short circuits that can shock and cause fires.
