Flood-Damaged Cars: Tips for Owners and Shoppers
Images of swamped cars during Hurricane Sandy remind us that cars and water don’t mix well. But water is only part of the problem, according to automotive and travel club AAA. Abrasive dirt and other contaminants can cause major to vehicles often resulting in a total loss.

AAA released a list of tips for dealing with vehicles that may have been flooded. For car shoppers, particularly those in the used-car market, there is advice on how to spot a car that may have suffered flood damage.

“In addition to the obvious damage done to upholstery and carpeting, flood water is a corrosive and abrasive mixture of water and dirt that works its way into every seam and crevice of a vehicle,” said AAA spokesman John Nielsen.

“Most vulnerable are the engine, transmission and drive train, along with the fuel, brake and power steering systems. Unless dirt and other contaminants are completely removed from these important vehicle components, increased wear and premature failure can result,” Nielsen said. Engine computers, sensors and other electronics are susceptible to corrosion.

Most important: Do not try to start a flood-damaged car until a qualified mechanic has done the following:

  • Inspect mechanical and electrical components, and systems that contain fluids, for water contamination.
  • Drain flood water from contaminated parts and systems, flush with clean water or an appropriate solvent, and refill with fresh fluids. 
  • Inspect, clean, and dry electrical system components and connections.

Depending on the vehicle make, model and age, the cost of such an effort may exceed the car’s value. AAA encourages motorists to contact their insurance companies first for help in determining the best course of action when dealing with a flood-damaged vehicle.

To avoid buying a flood-damaged vehicle, arrange a pre-purchase inspection at a qualified shop. Inspectors will look for tell-tale signs of flood damage like dried mud under the hood or inside the trunk. A damp or musty odor in the vehicle is often a sign of trouble. New carpeting and upholstery in older vehicles may also be hiding serious problems.

A vehicle history report can also be helpful. While they may not catch every potential problem the usually indicate when a car has been flooded or has a salvage title, which is a sign of a troubled past.
