MILWAUKEE (CBS 58) -- The Wisconsin Department of Transportation Division of Motor Vehicle (DMV) is urging caution when purchasing a used vehicle to check it carefully for potential flood damage. 

Southeast Wisconsin saw historic flooding in early August, causing many vehicles severe damage. 

According to the DMV, water may cause mechanical or electrical issues and affect the overall safety of the vehicle.

The DMV has resources to help identify damaged vehicles, tips for car buyers, and support if a faulty vehicle is purchased from a Wisconsin dealer.

“It may be difficult for consumers to identify whether recent floods have damaged a vehicle they are looking to purchase. Flood damage can be serious and not apparent until months after the flood. Dealers must clearly indicate if a vehicle they are selling has any flood damage,” Wisconsin DMV Dealer and Agent Section Chief Maura Schifalacqua said.

For car buyers unsure about a vehicle’s history or if you sense any problems, be cautious because you may not immediately notice the effects of flood damage which may lead to substantial and expensive repairs later on.

Anyone considering buying a vehicle should begin by thoroughly inspecting it. Wisconsin DMV offers tips on what to watch for when buying a used vehicle:

• Check for a damp or musty smell.
• Look for water stains, discoloration or mud in the engine, trunk areas, or the interior, including under the carpet and hard-to-reach areas.
• Test the functionality of electrical components, Moisture, condensation or corrosion could indicate damage. Ensure all components work properly.
• If possible, have your own mechanic inspect the vehicle prior to purchasing the vehicle.

Know the vehicle’s history

The Wisconsin Buyer’s Guide, the inspection sheet that discloses the vehicle’s condition and price, must be displayed on every used vehicle sold by a dealer. It documents the dealer’s visual inspection and test drive of the vehicle.

If the vehicle has been branded flood damage, it must be disclosed under the Title Brands section on the Wisconsin Buyer’s Guide. The guide provides the following information:

• How a vehicle was used (private use, business use, lease use, rental, etc.)
• Price
• Title brands (including Flood damage or Salvage)
• Make, year, model, identification number, engine size and transmission type
• Sold with remaining manufacturer's warranty, a dealer warranty or "As Is"
• Description of the items the dealer inspected
• Condition of the vehicle and its safety equipment, with defects explained.

Car buyers should also get a vehicle history report from providers such as Carfax or AutoCheck. These are like background checks for a vehicle. Most reports include historical details such as title records, crashes, service or repair records, and information about the vehicle’s mileage history. This may include any flood damage.
