There is a new recall at Ford, this time covering a very specific slice of the Bronco trim walk and concerning the possible failure of critical suspension pieces. The company doesn’t yet have a fix for the problem.

Ford is recalling 149,449 examples of its body-on-frame Bronco because of rear shocks that can fail due to corrosion. This recall only affects Broncos with external reservoir shocks, which includes Badlands and Broncos equipped with the Sasquatch package. Ford says the remedy is under development, and that it will notify owners by mail.
