Fiat Chrysler is recalling about 646,000 SUVs. The recall covers 2011 through 2014 Dodge Durangos, and 2011 through 2014 Jeep Grand Cherokees.
The company says brake booster shields were added as part of that prior recall. However, a check of warranty claims found that some weren’t installed correctly.
In those cases, water can cause corrosion or get inside the booster and freeze, reducing braking ability.
Fait Chrysler says it knows of one potentially related crash but no injuries.
Dealers will inspect the shields and correct the installation if needed.
