A flood damaged car is not something you want to buy. Floods can cause a lot of damages to cars. You can’t just wash away the water and everything will be back to normal. Flood damage is very expensive and it will cost you even more if you don’t get it fixed in time.
Here we will be providing some information about what flooding does to cars, why buying one of these cars is not a good idea, and what can happen if they are not fixed in time. It’s good to look out for the tell tale signs if you are buying a used car.
Freak weather conditions, global warming and storms can lead to floods and where there are floods there are damaged cars. These used cars are generally known in the business as “flood cars.”
Now I know what you are thinking, “I don’t live in an area prone to floods, so I am not at risk of unknowingly purchasing one of these flood cars.” Sorry, but you are dead wrong…actually the farther away you live from the hurricane damage, the greater you are at risk for being scammed into buying one of these cars.
Why are you more at risk? Think about it. Local residents will be much more on the ball about flood damaged cars. Away from the coast or big rivers, there may be less knowledge though. The scam artists behind these flood cars know this. This issue is huge and will hurt many people who make the mistake and purchase one of these vehicles. Even 4×4 vehicles can be affected even though they tend to be a bit more protected from floods due to the higher engine.
What is the big deal about a car that got water inside it if it seems to run just fine? The engine itself might be fine, and long term engine damage might not have occurred, but there are many other components of the vehicle that can seem to be working normally now, but can deteriorate in the near future.
Electrical components and wiring are usually affected most. There is a ton of complex wiring under the hood, in the dashboard, and under the carpeting of the vehicle. Water gets inside the vehicle from underneath from holes in the frame and body and around the door openings. If the carpet gets wet, so does the vast network of wiring under the carpet. The carpet can easily be replaced, but the wiring under the vehicle is usually too complex and therefore too expensive to replace, so new carpet is laid on top of them, concealing potential damage.
So what if the wires get wet? Rust is what will cause the problem. These wires will now slowly begin to break down and rust will form on any part of the wire that is not protected. When the electricity traveling inside these wires makes contact with this rust, resistivity will increase and the electricity will stop traveling. Whatever component the electricity was traveling to, a fuel pump for instance, will soon stop working. Finding the trouble spot in the miles of wire is not an easy task. The carpets and seat will probably have to be removed and hours of diagnostic time will probably be accumulated as the mechanic tries to find the trouble spot.
In most cars, the onboard computer system is located in the lower part of the passenger dashboard area, just inches above the carpeting. Some Japanese vehicles have the computer located under the passenger seat, on top of the carpet. If the computer system gets wet, not only will it need to be replaced, but it can damage many other electrical components as well.
Transmissions are another big ticket item that can be affected by water and not show symptoms for some time. When moisture enters the transmission, the normally light pink fluid becomes a light white/pinkish frothy mix, like a strawberry milkshake. The entire workings of the transmission are extremely complex and full of wires, sensors, and lots of rubber seals and O-rings. The water will cause the rubber parts to swell and leak, and the sensors and electrical components will soon succumb to rust and water damage as well.
So what can you do to protect yourself from buying a flooded time bomb?
1. Be cautious of every used car on the market.
2. Take your time inspecting and test driving. A good deal today is usually a good deal tomorrow too, so don’t succumb to pushy sales people.
3. Inspect under the driver and passenger seats for obvious signs of rust on the seat tracks and metal seat frame.
4. Look at the headliner (the fabric on the roof inside the car). Once wet, the glue that holds this fabric in place will begin to weaken, and the fabric will begin to fall down completely, or will fall in small sections that will look like bubbles.
5. Inspect the undercarriage and the exhaust system for signs of large scale rust. I would expect a small amount of rust as being normal; ask your mechanic if you have questions.
6. Use your nose. If the inside of the vehicle smells damp and moudy, or feels damp to your skin, you need to walk away.
7. Remove the wheels and inspect the brakes. This should be done anyway if you are inspecting a used car, but rust damage will really show itself on the brake components.
8. Inspect all under-hood fluids for water contamination. Oil and water will look like a chocolate milkshake, oil and transmission or power steering fluid will look like a strawberry milkshake.
9. Get the dealership or the seller to give you a written statement that to the best of their knowledge that the car has not been in a flood, and the car was not involved in any type of insurance claim that might have resulted in the original owner selling the vehicle to their insurance company as a “total loss.”
10. Look in the boot under the carpeting and under the spare tyre. Water and rust will tend to puddle here since it is one of the lowest places of the vehicle. If you see standing water, or signs of rust in and around the spare tyre area it is probably a flood damaged vehicle and should be avoided.
