Fiat Chrysler says it has recalled 646,394 SUVs in the U.S. to inspect if its brake-booster shields were properly installed. 

The automaker said that another 42,304 SUVs were recalled in Canada and 21,139 in Mexico. The recall affects 2011 to 2014 Dodge Durango and Jeep Grand Cherokee SUVs, FCA said in a statement.

According to a National Highway Traffic Safety Administration notice, corrosion may develop within the brake booster owing to a water leak, a condition that can limit braking performance. Apparently, shields designed to protect the booster may have been incorrectly installed during a fix from a previous campaign in 2014. 

FCA noted that "A booster compromised by water will still deliver brake function in compliance with US federal safety standards. However, customers may experience excessive brake-pedal firmness." The automaker says that a booster problem telltale could include activation of the vehicle's antilock brakes or illumination of a warning lamp.

FCA says it is aware of a single accident that may be related to the brake booster shield problem, but notes that the incident in question did not result in any injuries.

Dealerships will inspect vehicles under this campaign and remedy improperly installed shields and/or the boosters themselves as needed, free of charge.
