AAA study: Road de-icers cause $3 billion annually in rust damage
(March 4, 2017) ORLANDO, Fla. — As the end of winter approaches, millions of Americans will face pricey vehicle repairs from rust damage caused by chemicals used to de-ice roadways. According to a new AAA survey, U.S. drivers paid an estimated $15.4 billion in rust repairs caused by de-icing methods over the last five years, or approximately $3 billion annually.
AAA warns drivers, especially the 70 percent (150 million) who live in areas affected by snow and ice, to take action to prevent dangerous rust-related vehicle damage to brake lines, fuel tanks, exhaust systems and other critical vehicle components.
“While the application of de-icing salts and solutions is critical to keeping our nation’s roadways safe every winter, it’s important that drivers pay attention to warning signs that their vehicle may be suffering from rust-related damage,” said John Nielsen, AAA’s managing director of Automotive Engineering and Repair.
“This can be much more than a cosmetic issue, it can also create serious safety issues for drivers by impacting brake lines, exhaust systems, fuel tanks and electrical connections.”
AAA strongly urges drivers who experience any of the following vehicle malfunctions to immediately move the vehicle off the road to a safe location and have it towed to a trusted repair facility.
In-dash warning lights for brakes and other critical systems.
A “spongey” or soft feeling when applying pressure to the brake pedal.
An unusually loud exhaust sound or the smell of fumes in or around the vehicle.
The prominent smell of gasoline or diesel fuel when the vehicle is parked or running.
In recent years, many state and local transportation departments have shifted from using rock salt to liquid de-icers to combat ice and snow on the roadways. These newer alternatives are more effective than traditional salt because they can be applied before a snowstorm, have a lower freezing point and melt ice and snow faster.
However, these same characteristics can be even more damaging to vehicles since the chemicals remain in liquid form longer and are more likely to coat components and seep into cracks and crevices where corrosion can accelerate.
“In the last five years, 22 million U.S. drivers have experienced rust damage to their cars due to salt and liquid de-icers,” continued Nielsen. “In addition to the safety risk, repairs to fix these problems are often costly, averaging almost $500 per occurrence.”
While some rust damage is unavoidable, AAA recommends drivers take the following preventative steps in order to reduce the possibility of vehicle damage:
• When possible, limit driving immediately before, during and after winter storms when salt and de-icing solutions are being applied and are at their highest concentrations.
• Frequently wash your vehicle, paying particular attention to the undercarriage. This will loosen, dissolve and neutralize road salts. Many drive-through car washes offer an undercarriage rinse as an option.
• Always use a high-quality car wash solution, not a household dish detergent that will strip the wax from your vehicle.
• Repair any body damage and touch up paint scratches and chips that expose bare metal which could lead to rust.
• Before the start of winter, thoroughly wash and clean your vehicle prior to the start of winter and apply a coat of wax to protect the finish.
• Give the entire vehicle and undercarriage one last cleaning in the spring. Any deposits left over from winter can continue to cause corrosion year-round if not properly removed.
Pothole damage is another concern for drivers, as snow and ice melt and roadways begin to crumble. A new AAA survey found that nearly 30 million U.S. drivers experienced pothole damage significant enough to require repair in 2016, with repair bills ranging from under $250 to more than $1000. To address this issue, AAA believes that more funding is needed to keep pace with critical repairs and ongoing maintenance of the nation’s roadways.
