What Happened
The Electronic Control Unit (ECU) in your Acura TSX is like a brain that helps control your engine's performance. It's located under the floor mats, which can get wet when you walk in from the outside, especially in regions that use corrosive deicing materials.
Risk if Unfixed
If the ECU gets damaged from the corrosion, your engine could stall while you're driving. This increases the risk of a crash, as you'll lose control of the vehicle.
Free Fix
Your Acura dealer will inspect the ECU and replace it if it's damaged, at no cost to you. They'll also install a waterproof cover to prevent future damage. This repair is free, and you should contact your dealer as soon as possible.

Original — What Happened
Honda is recalling certain model year 2004-2008 Acura TSX vehicles originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin and the District of Columbia. In states that use corrosive materials for deicing, driver's footwear may bring in materials that saturate the vehicle's carpeting, which is in contact with the vehicle's engine Electronic Control Unit (ECU). As a result, the ECU case may experience rust or corrosion. This damage may potentially cause the engine to stall.
