Car buyers throughout the nation can experience the aftereffects of destructive floods by unknowingly purchasing water-damaged cars. New and used vehicles damaged by significant flood events, like Hurricane Ida in 2021, can find their way to the market in the aftermath of a storm. Carfax data shows that as many as 212,000 vehicles may have been damaged by Hurricane Ida. When flood-impacted cars are resold, unsuspecting buyers often face expensive mechanical and electrical problems that surface months later.
Even if you don’t live in a region where flooding is common you can still inadvertently purchase a car that has water damage. Carfax research also shows that water-damaged vehicles appear in every state, meaning buyers from coast to coast are at risk of purchasing a flood-damaged car.
How to tell if a car has water damage
Water-damaged cars can be hard to spot. They often look fine and may even run well for a little while. Eventually, however, you are likely to face problems as flooded cars rot from the inside out. Here are some of the signs that a car may have water damage:
- Musty odor: The interior of water-damaged cars will often smell musty. Unscrupulous sellers may try to hide the scent with powerful air fresheners, but it can be very difficult to truly rid a car of a moldy aroma. One way to test how a car smells is to sit inside and close the windows.
- Moist or damp carpeting: Water damage can collect in places you don’t immediately see such as underneath carpeting. Feel the carpets throughout the car and pat them to try and locate any potential moisture buildup. Check the trunk as well, even removing the spare tire to check for water beneath it.
- Stained or mismatched upholstery and carpeting: Yet another sign of water damage is a car with loose or stained upholstery and carpeting. Look for blotchy, brown stains, which are signs of water damage. When conducting inspections, compare floor carpeting to the upholstery on the doors and the roof. They should all look to be of similar age and color.
- Rust: A vehicle with water damage may have rust around the doors, inside the hood or even under the dashboard. Screws, door hinges, trunk latches and even door handles may also show signs of rusting.
- Brittle wires: Check under the dashboard if you suspect a car may have water damage. Brittle wires can indicate that the vehicle has been impacted by a water event of some type.
- Fog or moisture beads: If a vehicle’s interior lights, instrument panel or exterior lights look foggy or have moisture beads inside them, consider it a warning sign that the vehicle may have water damage.
- Mud or silt buildup: During flood events specifically, water can carry mud and dirt into a vehicle. Once the flood is gone, the dirt will remain. Some of the places to check for mud and silt include the glove compartment, trunk, under the dashboard, and below seats.
4 tips to avoid buying a flooded car
If you suspect that a vehicle may have water or flood damage, it’s important to do your homework and find out whether your instincts are correct. There are many tools available to help you get to the bottom of this important question, as well as signs to be alert for.
1. Run a vehicle history report
Running a vehicle history report can help uncover issues with a car before you make a purchase. A clear sign of a water-damaged car is one that is branded as such. Departments of motor vehicles require permanent title marks for vehicles that have been badly damaged by floods. If the vehicle was declared totaled, it is supposed to be given a new title entirely that is labeled “salvage” or “flood.” Depending on the state, however, this fact may be indicated by a numeric code.
Carfax and Experian offer flood check tools that allow users to conduct a free check on the history of a car. These platforms simply require entering the VIN of the vehicle in question. When reviewing a car’s history, keep your eye out for vehicles originating from areas that have been affected by flooding. The National Insurance Crime Bureau also provides free online VIN checks that allow consumers to find out whether a car has been declared salvaged.
You will want to look at a vehicle’s history report for any sign that the car has changed hands several times over a short period of time. Be particularly leery of a history that involves buyers in multiple states. This could be a sign of what’s known as car “title washing,” where unscrupulous sellers retitle a car repeatedly to hide its history.
2. Check for signs of water damage
Cars that have been even partially submerged in water often have telltale signs, but they may be subtle, especially if the car has been cleaned up for resale. Pay attention to musty or moldy smells, including those coming from the climate control system.
Note any stains that appear on the car’s interior, engine compartment and trunk. Dirt, sand or mud in odd places and seat belts that sound gritty when they are pulled or retracted are also signs of water damage.
It’s also important to test drive a vehicle, especially one you think may have water or flood damage. Hints to watch out for during a test drive include compromised electrical systems and infotainment systems, which will act up if they have been impacted by water. You will also want to look for signs of smoke during your test drive.
3. Be wary of cars that are priced below market value
There’s a reason for the adage about things being too good to be true. This includes cars being priced well below their market value, which is often a red flag that something is wrong.
Check the typical selling price for the car you are considering buying on independent vehicle pricing sites such as Edmunds and Autotrader. A new or used car priced below market value is a strong indicator the seller is anxious to get rid of it.
Buyers should tread cautiously when a car is being listed for a significant discount. In addition to asking questions about why the car is being offered for much less than it should be, it may be a good idea to have the vehicle looked at by a professional who can identify any problems.
4. Get a professional inspection
It’s always a good idea to hire a certified mechanic or automotive technician to thoroughly look over a car before you buy it, but it’s even more critical to take this step in order to protect yourself from a possibly water-damaged car.
A professional can help ease your mind, especially if the car you are considering has one or more of the warning signs listed here. Be sure that the inspection not only includes obvious signs of water damage but also a thorough test of all the electronics equipment, as problems with these systems can take months to surface.
While a pre-purchase inspection will typically have to be paid for by you, the prospective buyer, it will be money well spent if it prevents you from ending up with a car that is a lemon. You can expect to spend from $100 to $200 for an inspection.
What to do if you bought a water-damaged car
If you’ve purchased a vehicle that has water damage all may not be lost. It is possible to repair the vehicle with an experienced mechanic. But remember, these are not do-it-yourself fixes. It will require a professional who has extensive knowledge of cars.
It’s also worth bearing in mind that repairing a flood-damaged vehicle will not be cheap, so you’ll want to determine whether the car is worth the investment. Especially since flood-damaged cars typically have no resale value.
The bottom line
Flood-damaged vehicles are in use in every state across this country. If you suspect a car may have been impacted by flooding or some other type of water event there are several steps to take including running a vehicle history report, looking for telltale signs of water damage and having the car inspected by a professional. Remember, even if you don’t live in an area impacted by flooding, you could unknowingly end up with a water damaged vehicle.
