The 2013 and 2014 Ford F-150 pickups with the 3.5L six-cylinder engine are being probed by the National Highway Traffic Safety Administration, with Ford’s full cooperation. This is not a recall and may never rise to that level, but since this is a very popular vehicle and there are about 420,000 of them in the field, I though you should know about it.
There have been more than 30 complaints about brakes failing in these vehicles — 20 within the past seven months. Drivers reported that pedals can suddenly go to the floor with complete loss of braking, and mechanics have told some drivers that brake fluid had leaked from the master cylinder to the brake booster causing the problem.
I some cases, it was reported that brake warning lamps came on or that brake fluid reservoirs were found to be low or empty with no visible leaks. Ford has said that any owner who has a concern about the brakes should contact the dealer.
Ford sold more than 660,000 F-series pickups in 2013 and more than 750,000 in 2014, and the pickup is the most popular vehicle in the nation. Trucks with other engines could be included in the probe as Ford says that they share the same braking system.
At this time, this is strictly an engineering analysis according to the NHTSA, and I will keep you informed if anything changes.
