Throttle body malfunction - causes loss of power while driving. Acts as though you took your foot off the gas pedal. Engine will not rev above idle speed. Check-engine light comes on. If you stop, turn off the car, and re-start, it will be ok for a while. It happened to me twice in 2 weeks. Part was replaced, but the new part failed again in 16 months. Had that replaced this week. (may '17). I am aware of ford customer satisfaction program 16b23, but the dealer said my VIN was not one of the affected vehicles. I beg to differ.

On august 1, 2016, at approximately 7:30 p.m., I was driving south on u.s, highway 1 (y,s, highway 2 is a 3-lane road). Suddenly, my vehicle lost the poser to accelerate. I was panicked, as there was traffic behind me and to my left side. I could do nothing to stop the loss of acceleration. Fortunately, my friend as following me and was immediately aware that I was having a problem. My friend immediately put on his emergency flashers; as I slowed, I was able to pull off to the side and coast into a filling station. At this time, I noticed two things; the car ran roughly at a very slow speed and a wrench symbol appeared on the dash. I was able to pull to a safe location on the filling station lot. My friend searched for the symbol in the owner's manual which indicated there was a throttle control problem and I should contact my dealer immediately. At this time, I called aaa and was advised that a tow truck would be there in approximately an hour and a half. When the tow truck arrived, I completed the paperwork and the car was take to paradise ford where I purchased it in 2012. The following morning, ford called me and diagnosed it as a defective throttle body assembly and replaced it. Some research indicated that a tsb had been issued to ford dealers about the malfunction of this item. Because in my case, this was an obvious safety issue, I feel ford should have notified me and given me the opportunity to have it replaced under warranty. As a result of this, I was charged $621 for the repair. To reiterate, the main issue here is that in an unsafe situation due to, what I perceive, as the ford dealer's negligence.

Intermittently, while driving at any speed the vehicle will go into 'limp home mode'. The 'wrench' trouble light illuminates on the dash. The vehicle then has to be stopped completely, put into park and shut off. The vehicle then starts after a few extra cranks of the starter and runs normally. The 'wrench light is no longer lit and no engine code is stored. My mechanic cannot troubleshoot the problem because no engine error code is stored. Research on-line points to defective throttle body as the culprit with replacement as the solution. Ford should add the mustang to its customer satisfaction program for defective throttle bodies. I understand some 1.6 million vehicles are already on this list. The problem began for me about a year ago around the 18k mile mark and the vehicle now has about 22k miles on it, is meticulously maintained and cared for. This is a very dangerous defect that we, as owners, could at least address properly if there was an engine error code reported. I am going to have the throttle body replaced at my own expense based on what others have reported, since there is no known fix from ford. I did report this to ford customer service today 04/23/2016. They confirmed they are unaware of any problem with mustang throttle bodies. I recommend that ford put some engineers on this and remedy the problem. In the meantime, we mustang owners with cars out of warranty are having to fend for ourselves.

Went to stop and had to put car into neutral before car stopped because gas petal would not release.

My vehicle constantly goes into limp home mode while driving. Turns off all cylinders except 1 which let's you drive about 5mph. Also while my vehicle is at idle it begins to loose proper idle RPM and nearly stalls until revs back to a higher RPM. After some research I found that the issue is thought to be the throttle body and throttle body sensor. Currently mymy vehicle is at the dealership going through some vehicle diagnostics to figure out the exact problem. They told me it is not covered under the vehicle warranty and I am being charged $145.00 for the initial inspection and then charged by the hour to fix the problem, I not including parts. My vehicle only has 59,000 miles on it and it's already failing. It appears that numerous people are have this issue and ford has yet to recall affected vehicles.
