Did Your Car Sit in Floodwater? What to Check and What to Do

In Jacksonville, flooded streets aren't just a hurricane problem. Heavy fall rain, storms that sit over the same neighborhood, and high tides near the river and the Beaches can all leave water standing where cars are parked.

If your car sat in that water, even for a few hours, it may have damage you can't see yet.

Here's what to check, what to avoid, and how to decide whether the car is worth fixing.

First Rule: Don't Start It

This is the most important step, and it's the one people get wrong.

If water reached the engine, starting the car can pull that water in and cause serious engine damage. Both AAA and State Farm advise against starting a car right after it's been in a flood, even if it looks dry.

Don't drive it to "test" it either. If you're not sure how high the water got, have the car towed to a mechanic instead.

Signs Your Car Has Flood Damage

Some damage is obvious. Some shows up weeks later. Look for:

• A waterline on the door panels, seats, dashboard, or engine bay
• Water or dampness under the seats, in the carpet, or in the trunk
• Moisture or fog inside the headlights or taillights
• A musty, moldy smell that doesn't go away
• Electrical problems, like warning lights, windows or locks that act up, or a radio that cuts out
• Brake or ABS warning lights
• Corrosion on metal parts, connectors, or under the dash

Take photos and videos of everything, including the waterline, before you clean anything up. You'll want that record if you file an insurance claim.

Why Saltwater Is Worse Than Rainwater

Not all floodwater is the same.

Rainwater flooding is bad. Saltwater flooding is worse. Salt speeds up corrosion, and that damage keeps working long after the car dries out. Electrical parts are especially at risk. A car that seems fine for a few weeks can start having electrical failures later, as corrosion spreads through wiring and connectors.

That matters in Jacksonville. Neighborhoods near the St. Johns River and the Beaches can see tidal flooding, which brings saltwater onto the streets. If your car sat in water near the coast or the river, treat it as possible saltwater damage and get the electrical system checked quickly.

We explain how salt air already wears down cars here in our guide on how Jacksonville's salt air and humidity destroy cars faster.

Does Insurance Cover a Flooded Car?

It depends on your coverage.

• Comprehensive coverage is the part of a car insurance policy that generally applies to flood damage. Policies differ, so read yours and confirm with your agent.
• Liability-only coverage, the legal minimum, generally doesn't pay for damage to your own car.

If you have comprehensive coverage, contact your insurer as soon as it's safe. Your insurer will likely compare the repair cost to the car's value to decide whether to repair it or declare it a total loss.

If your car is totaled, read our guide on what to do when insurance totals your car in Florida. It explains your options, including keeping the car and selling it.

Repair or Sell?

Flood damage is tricky because the first repair bill often isn't the last one. Corrosion and electrical problems can keep appearing for months.

Repairing may make sense if:

• The water stayed low, below the floor of the car
• A mechanic finds limited damage
• The car is newer or worth enough to justify the cost

Selling usually makes more sense if:

• Water got into the cabin, the engine, or the electrical system
• It was saltwater
• The repair estimate is close to, or more than, what the car is worth
• The car is older and you were already thinking about replacing it
