Fiat Chrysler Automobiles, United States will be recalling upwards to 900,000 SUVs due to the possibility of failing brake systems in cold weather.

Chrysler initially did not admit that their brake lines were corroding, but after an inquiry from the National Highway Traffic Safety Administration (NHTSA), the car company acknowledged the problems with their vehicles when temperatures dropped below freezing.

The recall spans Jeep Grand Cherokees and Dodge Durangos from 2011 through 2014. The recalls include over 644,000 sold in the United States, more than 42, 000 in Canada, and more than 180,000 in Mexico, Europe, Asia, and other parts of the world.

The defective braking systems were initially reported by a customer in 2013 when he noticed that the brake pedal on his SUV became difficult to push and that he lost braking power as a result. Upon further investigation, it was found that the problem was perpetuated by components in the SUVs' power brake boosters called crimp joints. The crimp joints would deteriorate, allowing water to clog the brake line. While water in the brake line is not unforeseen and most water in brake lines in generally pushed out by the air pressure, if that water were to freeze in subzero temperatures, it could prevent air from circulating, thus causing the brakes to fail.

Fiat Chrysler's plan is to tell owners of these defective vehicles over the next month or so. The car company promises to fix the problem at no cost to its customers. They have developed a shield to fit around the malfunctioning component that they say will keep water out of the vehicles' brake lines.
