When you’re checking out a Tokunbo car you want to buy, it’s easy to focus on whether it has ever been in an accident or not. Truth is, aside from worrying about the car’s accident history, you should also find out if it’s a flood-damaged car.

This is because many cars shipped into Nigeria look spotless on the outside, but some may have been soaked in floodwater abroad. And once that happens, the car can develop serious electrical and mechanical problems that aren’t always visible right away.

To help you avoid experiencing these issues, we've put this piece together to show you what to look out for before purchasing a car.

How You Can Spot a Flood-Damaged Car to Avoid a Bad Deal

  • Exterior Clues

      • Rust in Unusual Places: Floodwater increases the rate at which certain parts of the car become rusted. Some of these areas include the undercarriage, wheel wells, hood springs, trunk latches or brackets, and around door hinges. So, be sure to check for signs of rust in these hidden spots.
      • Discoloration on the Body: Look carefully at the doors, boot, wheel arches, and under the hood. If some areas of the paint look lighter, darker, or streaky compared to the rest of the car, it might have been underwater before.
      • Water Lines or Stains: Sometimes you can see faint water marks or lines along the body or inside the engine bay. These are leftover signs that the car was once submerged.
      • Foggy or Cloudy Headlights: If the headlights appear foggy or can't be cleaned, it might be a sign that the car has been in a flood.
  • Interior Indicators of a Flood-Damaged Car

      • Stains or Discoloration: Check the carpets, seats, and floor mats for unusual stains, fading, or watermarks. Even small patches can be a warning.
      • Rusted Seat Brackets or Bolts: Look under the seats and at the bolts that hold them in place. Rust here is a clear sign that water has been inside the car.
      • Mold or Mildew: Check under mats, inside door seals, and in the boot for any mold growth. Even a small spot of mold can point to past flooding.
      • Seat Belts and Upholstery: Pull on the seat belts and examine the fabric. If the material feels stiff or worn or smells odd, floodwater could be the cause.
  • Mechanical and Electrical Systems

    To identify if there are issues with the mechanical and electrical systems, take the car for a test drive and pay attention to:

      • Engine Issues: If the engine struggles to start or makes unusual noises once it’s running, it could be a sign of water damage to internal components.
      • Electrical Malfunctions: Flickering dashboard lights, malfunctioning sensors, or non-functional airbags may indicate water has affected the car’s electrical system.
      • Unusual Noises: Grinding, squealing, or knocking sounds from the brakes, transmission, or other moving parts can result from water damage.
      • Blown Fuses: Inspect the fuse box for signs of corrosion or blown fuses caused by water exposure.

    Importance of Running a VIN Check

  • Documentation and Vehicle History

      • Check the VIN: Use the Vehicle Identification Number (VIN) to obtain a history report. This can reveal if the car has been declared a total loss due to flood damage. While reading through the report, also be wary of vehicles with a "salvage" or "rebuilt" title, as these may have been repaired after significant damage.
      • Service Records: Inconsistent maintenance records or gaps in service history can be red flags.

Some Risks of a Flood-Damaged Car

    Even though flooded cars may appear less expensive to buy, they often come with hidden problems that can end up costing you far more than the purchase price.

    Here’s why you should think twice before buying a flood-damaged car in Nigeria:

      • Hidden Mechanical and Safety Risks: Flood damage can affect hard-to-see parts like the engine and electrical systems. Malfunctioning airbags or other safety features can put you at serious risk during an accident.
      • Rust and Corrosion: Water exposure can cause rust over time, damaging both visible and hidden metal parts. Repairs can be expensive and sometimes extensive.
      • Electrical Problems: Short circuits from water damage can cause dashboard issues, faulty lights, and even increase the risk of fires.
      • Structural Damage: Flooding can weaken the car’s frame, reducing its stability and safety.
      • Mold and Odor: Moisture trapped inside can lead to mold growth, unpleasant smells, and even health concerns.
      • Reduced Resale Value: Even if a flood-damaged car seems fine at first, its long-term value is often much lower than a car that has never been underwater.

Final Thoughts: What to Do If You Suspect a Car is Flood-Damaged

If you suspect a car has been affected by flooding, the safest choice is usually to walk away. Flood-damaged cars can hide rust, electrical faults, and structural problems that often appear weeks or months after purchase.

The only time it might make sense to buy one is if the seller has given full disclosure of the flood history and you plan to use the car for a short period, fully aware of the risks.

To protect yourself, always inspect the car carefully and verify its history by running a VIN check. Doing all these can prevent you from costly repairs in the future.
