The 2015 Mustang and the 2014 to 2015 Fusion and Lincoln MKZ are affected
Rust on the pedal’s mechanism could cause the brake lights to stay on and the interlock to malfunction
The affected vehicles are in hot and humid areas
In hot and humid climates, such as Hawaii and parts of the southern United States, rust can form on the brake and clutch pedal’s bumper.
The bumper is the part on which the pedals rest at the top of their travel when they are not depressed.
This corrosion could prevent the brake pedal from releasing fully, which causes the brake lamps to stay illuminated during regular driving. This could increase the risk of accident by making other drivers confused and thus potentially not notice when the affected vehicle is slowing down or stopped.
Another issue that can be caused by this problem is that the interlock for the automatic transmission could fail to engage if the brake pedal doesn’t release enough to hit its safety switch.
This interlock prevents the transmission from being shifted into gear without applying the brakes. Doing so could lead to damages and injuries because the car could suddenly lurch forwards or backwards if the shifter is accidentally bumped, or a child could put the vehicle in gear while the driver is not in the car, which is the reason why this safety was implemented back in the 80s and 90s.
To rectify the problem, Ford will send out letters to the owners of the vehicles at risk for corrosion starting on March 3.
Dealers will replace the brake pedal bumper as well as the clutch pedal bumper in vehicles equipped with a manual transmission. Since this is a safety recall, the repairs will be made free of charge.
