AAA Northeast Warns Consumers About Flood-Damaged Cars Entering the Used Car Market After Flash Flooding 

Flash flooding that recently impacted much of the Northeast — including parts of Connecticut, Massachusetts, New Jersey, New York and Rhode Island — may have an additional consequence: flooded vehicles making their way to the used car market. Over 480,000 flooded vehicles nationwide were back in use in 2025, up 6% from 2024, according to CARFAX.  

Floodwater can compromise a vehicle’s mechanical and electrical components, potentially damaging the engine, exhaust system, wires, brakes, airbag system and more. Mold and mildew inside the vehicle can also cause health concerns.    

Insurance companies often declare flood-damaged vehicles as total losses, and many are sent to auto recyclers for dismantling. However, vehicles assigned a salvage title may be refurbished and reenter the marketplace. But without trusted documentation, water-damaged vehicles can be difficult to identify. 

AAA Northeast offers the following tips for spotting a flood-damaged vehicle:  

• Check for damp or musty odors inside the vehicle.  

• Pull back the carpet to look for mud, rust or water stains, especially in used cars where the carpet has been replaced or recently shampooed.  

• Open the trunk, hood and doors to inspect for debris or corrosion on the door frames, hinges and under the weather stripping. Check for rust on the underside of the vehicle.  

• Check for brittle wires under the dashboard.  

• Inspect the engine air filter for signs of water damage or staining.  

• Look for fog or moisture in the interior and exterior lights, as well as the instrument panel.  

• Check all warning lights, window motors, air conditioning and other electrical components to ensure they’re working properly. While a malfunctioning part alone doesn’t indicate flood damage, combined with other signs of potential water damage, it could be a cause for concern.  

• If the price looks too good to be true, it probably is. Used car prices remain historically high, CARFAX reports. Find a reputable dealership when looking to purchase a used car.   

Consider acquiring a CARFAX Vehicle History Report before purchasing a used vehicle. The report may reveal if the car was involved in a flood or issued a salvage title. Potential buyers can also have the car inspected by a trusted mechanic at a AAA Approved Auto Repair Facility. 

Frequently Asked Questions 

How common are flood-damaged vehicles? 

According to CARFAX, more than 480,000 flood-damaged vehicles were back in operation nationwide in 2025, representing a 6% increase from the previous year. 

Why are flood-damaged vehicles a concern? 

Floodwater can affect critical systems throughout a vehicle, including the engine, transmission, brakes, electrical wiring, sensors, airbags and exhaust components. Damage may not become apparent until months after purchase. 

What are the most common signs of flood damage? 

Potential warning signs include musty odors, water stains, rust, mud under carpeting, moisture inside lights, brittle wiring and corrosion. 

What is a salvage title, and why does it matter? 

A salvage title indicates that a vehicle was declared a total loss by an insurance company. This often occurs after significant damage such as flooding. Buyers should review title history carefully before purchasing a used vehicle. 

How can I find out whether a vehicle has been damaged by flooding? 

A vehicle history report may reveal if a used vehicle sustained flood damage or was issued a salvage title. 

Should I have a used car inspected before buying it? 

Yes. Before purchasing, AAA Northeast recommends having a used vehicle inspected by a trusted mechanic, such as one at a AAA Approved Auto Repair Facility. 

If a used car is priced much lower than similar vehicles, is that a warning sign? 

Potentially. If an unusually low price seems too good to be true, it probably is. Buyers should look to purchase from a reputable dealership and carefully investigate a vehicle’s history before purchasing.
