Defect
On certain vehicles, brake fluid could leak from the brake master cylinder into the brake booster. If this happens, there could be reduced braking. Note: This problem may cause a warning chime to sound and a red brake warning indicator to display in the instrument cluster. This recall only affects certain vehicles equipped with a 3.5 L Ecoboost engine. This is an expansion of recall 22S11 (Transport Canada recall no. 2022-115).
Safety Risk
Reduced braking can cause extended stopping distances and increase the risk of a crash.
Remedy
Ford will notify owners by mail and advise you to take your vehicle to a dealership to replace the brake master cylinder. The dealer will also inspect and, if necessary, replace the brake booster.
