2008 Ford F-150: adaptive cruise control problems

Filed Nov 22, 2019 · Acceleration · 115,600 miles · UT

Had cruise control set while driving along freeway. Needed to slow down and tapped brake to release cruise control. Nothing happened. Pressed brake again to slow down and engine power increased to coincide with cruise control setting. Manually shut off cruise control and it disabled. Cruise control currently will not shut off by utilizing brake system.

Sitting in my truck with the key turned or even on idle, the electronics on my dash(radio allumination, trip box, etc.) will be faded on one side or will be completely faded and I cant see the time, station, gas mileage, etc. From time to time when it does this, my cruise control figure wont show but after a while(10-30 minutes) it will pop up on the cluster. It doesnt matter if its cold out or hot out, idle,running or ignition switched off, it will be faded. Its becoming more of a common thing(daily).

05/31/2013 purchased used 06/29/2011 2008 ford 150 mileage: 26,440 issue: accelerator has stuck two times in town. 1st incident: 07/18/2012 mileage 32,000 driving in town with no cruise control being used. Preparing to turn at intersection, speed about 10 MPH, when engine started to roar. First reflex was to press brake which caused the tires to squeal. Put in neutral which caused the engine to slow down to normal. 07/19/2012: took to ford dealer they stated with out the check engine light being on they could only guess as to what the cause may be. Have enclosed the work order. Invoice states cruise control sticks, but both incidents the cruise control was not being used. 2nd incident: 05/29/2013 mileage 40,260 slowing down for a red light in town, speed about 15 MPH, engine started to roar, put in neutral, engine slowed down. My wife and daughter both drive this vehicle occasionally, I am afraid they might not get it into neutral soon enough to keep from causing injury to a person or anything in the path. 07/18/2012: repair consisted of cruise control switch. With out the engine light being on, they just had to guess as to what repair to do.the shop manager said if it happened again they would just have to keep the vehicle and drive it to see if this problem would recur. This would cause us not to have use of the vehicle for possibly months. Vehicle functioned fine until 05/29/2013. If I were to return to the dealer, they again would have to make a guess as to the repair needed. Please make recommendations as to what I can do with this issue.

Tl*the contact owns a 2008 ford f-150. While driving approximately 50 MPH with the cruise control engaged, the engine began to rev at full throttle and the vehicle accelerated unexpectedly. There were no warning indicators illuminated on the instrument panel. Immediately, the cruise control was disengaged to slow the vehicle down. The failure occurred sporadically. The vehicle was taken to an authorized dealer for diagnostic testing, but they could not duplicate the failure. The failure recurred on two separate occasions, in which the most recent failure contributed to the vehicle lunging forward unexpectedly into the preceding vehicle. There were no personal injuries and both vehicles sustained minor damage. The police was called to the scene and filed a report. The vehicle was towed to the authorized dealer for diagnostic testing and repair. The contact is waiting on a response as to what caused the failure. The failure mileage was 18,000 and current mileage was 23,000. Updated 12/8/09 *cn updated 12/09/09

Re: 2008 ford f-150 I picked up a new ford f-150 yesterday and had an event occur while slowing in preparation for stopping behind a line of stopped vehicles at a red traffic signal. Instead of slowing the vehicle when the brake was gently applied, the vehicle acted like it was on a sheet of ice. I could "feel" the ABS brakes trying to stop the vehicle, but it seemed to be accelerating on it's own. I barely missed the vehicle in front of me and a light pole near the edge of the road, since I had to steer off of the road and onto the sidewalk area where I immediately put the transmission into neutral and turned off the ignition. I called the dealership and they sent a mechanic who returned the vehicle to the service area and checked all of the systems. They told me that there were no problems found and that I must have applied the brake and accelerator at the same time. I absolutely did not do that. I tried to apply the brake and accelerator simultaneously after returning home, and it is possible, but very difficult and uncomfortable to do. I have found other documented cases of the same problem with other f-150s. I had used the brake to stop the vehicle safely several other times before this incident. The odometer read only 10.4 miles when the event occurred. The cruise control feature was not enabled when the event occurred.
