DEARBORN, Mich. -- Ford is recalling about 213,000 police vehicles in North America to fix springs that may not keep doors closed in a crash.

The recall affects Ford Explorer and Police Interceptor utility vehicles from the 2011 through 2013 model years.

The company traced the problem to a spring that controls the interior door handles. The spring can become unseated and may become unlatched in a side-impact crash, increasing the risk of injury.

Ford said it doesn't know of any crashes or injuries from the problem.

Dealers will inspect all four doors and fix or replace the handles if needed, free of charge.

Ford also is recalling about 6,500 Super Duty ambulance and emergency vehicles from 2011 through 2015 with 6.7-litre diesel engines. The exhaust gas temperature sensors can malfunction.
