Four problems related to brake light on have been reported for the 2005 Ford F-150. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2005 Ford F-150 based on all problems reported for the 2005 F-150.
Brake warning light is lit on the dashboard. There is nothing wrong with the brakes. I have read that there is a wiring problem which causes the brake light to stay on. Ford has recalled other f150 model years but not 2005 f150s.
The brake lights stopped working and the speed control brake pedal disconnect stopped working. Speed control disconnect was achieved by using the steering wheel control but if the stopping situation had been an emergency one, an accident could have resulted as there was about a 1. 5 second delay for me to figure out what was going on and correct the situation. While travelling at 70mph on I-10 with the speed control engaged, I went to exit the highway to get fuel and while depressing the brake pedal to reduce speed, the speed control began attempting to resume the original 70mph speed by revving the engine. Later I determined that the alternator on the vehicle had failed and while the battery had enough voltage to keep the engine running and the voltage gauge had not moved yet, the battery did not have a full 12. 5v output. When the brake pedal sensor does not have a full charging voltage input, it seems to stop working. Therefore, the speed control disonnect failed and the brake lights failed to activate even though the motor and other components continued functioning normally. It seems that the brake pedal sensor is very voltage dependent (which was not the case on other vehicles I have owned). I notified Ford of the situation after the incident occurred and have received nothing in reponse. I got rid of the vehicle and purchased a different one as I believe it is not safe and could result in traffic tickets/accidents (no brake lights) and speed control disconnect failures (accidents) if there are voltage fluctuations in the electrical system.
Was driving my 2005 F-150 elt on 4 lane divided highway at approx 65-70 mph. When applied the brakes felt slight pull to the right. Began smelling strong odor once entered town and was slowed to 35 mph. Drove another 2-3 miles to home and smell intensified. Once exited the truck saw smoke coming from the driversfront tire. Front wheel was also extremely hot, was unable to touch it.
At 400 miles the vehicle shook violently when putting pressure on the brakes. This happened on may 18, 2005. Contacted the dealer, and then took the vehicle to the dealer, who claimed the rotors were warped from heat. They got permission from Ford to put on different rotors. After leaving the dealer the brake light came on. The consumer went back to the dealer. They checked and discovered there was no brake fluid in the master cylinder. Left the dealer again , went to apply the brakes and there was no brake fluid in master cylinder, the fluid was in the rims of the vehicle, and on the ground. This wore out the tires and the brakes still were not working properly. Ford was suppose to send a representative to meet with the consumer , and had not done so. Currently, the consumer went to a different dealer , and they just swapped the tires from the front to the back. Then , they changed/ turn ed the rotors. The consumer spoke with manufacturer , who blamed the dealer, but the dealer blamed the manufacturer.
