Tl* the contact owns a 2008 ford f-250 sd. After the brake pedal was depressed, it sunk to the floorboard and failed to operate. The contact was able to stop the vehicle by using the electric brake from a trailer being towed by the vehicle. The failure occurred without warning. The vehicle was towed to the dealer where it was diagnosed that the cruise control brake release switch failed and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 51,000. Updated 09/22/16*lj updated 10/6/2017

After appox. One hour at 65 MPH on cruise control I disengaged the cruise control , coasting to a speed of about 25 MPH or less to make a upcoming left turn. As I started to turn I pressed on the brake and found it was without assist, and the same was true for the steering. I applied as much pressure as I could to both the brake pedal and the steering wheel and fortunately made the turn with out incident. I tapped the fuel pedal and both the brakes and steering assist returned to normal. I've had the problem before with loss of brakes but have always been going straight. I report this to the dealership but since the vehicle doesn't show a error code they can't fix it! At least if I die in a crash this will be my record. I will report the truck again to the dealer but they wont fix it. I have seen that others are experiencing also. I won't let my wife drive the truck it is not safe!!! This is a design flaw the system is drawing fluid for both the brakes and steering from the powersteering pump, also I believe from what I have read the fluid travels thru a screen(filter) which can plug starving the system of fluid needed to properly operate the steering and brakes.

On 8/10/2010, after driving my 2008 f-250 on interstate 5 for about 6 hours continuously at approx. 70mph in cruise control mode, I overrode cruise control to accelerate and pass a vehicle. As I returned to the right side driving lane, the vehicle failed to reduce speed and continued to accelerate in an uncontrolled fashion. With heavy braking I was able control the vehicle and bring it to a stop on the highway shoulder where I shifted it into neutral and cut the ignition off. A restart of the vehicle resulted in an immediate run-up in RPM which could only be controlled by shutting down the engine. No engine or other warning lights were displayed. By opening the hood and manually resetting the air filter contamination sensor on the air intake duct, it was possible to restart the engine and have it operate normally. I did not again use cruise control. This is a repeat of the condition previously reported in id# 10279704. The common elements of all three instances of occurrence are that the engine has been operated at 65-70 MPH for approx. Six hours, cruise control is engaged, and the engine is either in or has just completed an exhaust regen cycle . Ford appears to be unable or unwilling to identify or address this situation, but it continues to be a severe safety hazard.

I have a 2008 f-250 s/d manufactured 02/08 at the kentucky plant. This vehicle was purchased new in april 2009 and now has just under 8000 miles on the odometer. I have twice experienced uncontrolled involuntary acceleration with this vehicle. The common elements of this have been that it occurred after a period of extended driving at about 70 MPH, using cruise control, just after an exhaust cleaning cycle, and when I overrode the cruise control to accelerate to pass a vehicle in front of me. When pulling back in to the traffic lane, the vehicle continues to accelerate and can be controlled only by maintaining heavy pressure on the brakes until a safe location can be found to pull off the road and cut off the ignition. A restart in neutral will result in an immediate run-up in RPM which requires a shut down of the ignition. There are no "check engine" or "service engine" lights displayed, and according to ford dealerships, no codes registered in the PCM. In both cases I have been able to correct the problem and continue to drive the vehicle (without use of cruise control) by pressing a "reset" button located on the top of a white sensor located in the air intake duct on the right side of the engine compartment. Ford says they are unable to duplicate the problem and consequently cannot "make a fix". I am most concerned because this is a significant safety issue.

Tl*the contact owns a 2008 ford f-250 sd. While driving 50 MPH, the instrument cluster, traction control system, cruise control, and air conditioning failed. All of the gauges displayed zero. The vehicle would operate, but nothing would display on the instrument panel. The vehicle would also stutter and then the gauges would function properly. The vehicle has been at the dealer for two weeks and they informed the contact that the instrument cluster was faulty and would be replaced under warranty. The current mileage was 1,000 and failure mileage was 10.
