The contact owns a 2003 Ford F-150. While driving approximately 20 mph, the brake pedal traveled to the floor when it was depressed and failed to stop the vehicle. The contact coasted to the side of the road and stopped the vehicle. The contact discovered that there was fluid leaking from underneath the front of the vehicle. The contact also noticed that the end of a flexible hose had excessive rust and was fractured where it was connected to the brake caliper. The contact was able to slowly drive the vehicle to his residence. The vehicle was not taken to the dealer. The manufacturer was not made aware of the failure. The approximate failure mileage was 55,000.

Driving down highway and exiting onto my exit, the truck started to run rough and eventually shut off. I had to wait about 1hour for the truck to cool off before it would start again. While waiting for the truck to cool off, I changed the fuel filter. Today, 6/3/15, I can start the truck up and let it run for about a half an hour and shut it off and it will not start back. I wait another half an hour and it will start right up. I can't effort to take it to the shop and pay $50 to $100 for them not to be able to tell me what is wrong or how to fix it.

F-150 8-cyl

  • 115,000 miles


Vehicle lost all power (in dry climate), including steering, and brakes at approximately 50mph. Came to a stop using the emergency brake. Had two near misses while attempting to come to a stop. Vehicle had to be towed as the ECM (engine control module) was no good. Had prior misfires in engine, which Ford had diagnosed as a bad head valve. After rebuilding the heads, the problem continued (while under use in dry climate). Incident occurred, at which point the vehicle had become disabled. 2nd Ford dealership diagnosed as "electrical problems" which had allegedly caused the vehicle's ECM (engine control module) to short out. No more than 500 miles and/or 3 days after replacement of the ECM and fixing of unspecified "electrical problems" (and in moist climate), vehicle would have periodic misfires which would on occasion be so severe so as to drop all gauges on dash to their "off" positions, but with the engine still running (under stress from supposed misfire which would shake the entire truck). On two later occasions, while idling at a stop light the vehicle would repeat the same condition as with the initial incident, where the vehicle would completely shut-off, with exception that on the repeat occasions, the ECM was still functional and I was able to restart the vehicle. A 3rd Ford dealership was unable to diagnose exact problem but suggested replacement of coils followed by wiring as a possible fix to the misfire. I removed the vehicle to a dry climate and replaced all plugs, coils, and boots for testing. Vehicle successfully functioned under dry, moist, and snowy climates afterwards. Continues in operation and is currently at +/- 155,000 miles.

Without warning, the brake pedal went to the floor while towing a 6000lb trailer. Stopped for dinner - all felt normal. Upon finishing dinner and returning to my truck, I put my foot on the brake and shifted from park to drive when suddenly the brake pedal went to the floor. I tried several more times and each time the brake pedal went to the floor. Inspection of the vehicle showed that the brake line leading to the rear brakes had rotted through from the outside. This vehicle is meticulously maintained and has never been used near salt water, or to launch boats. My mechanic has advised me that rotting brake lines is a common problem. With that knowledge, I am dismayed and disappointed to find out that Ford does not offer any type of replacement lines.
