2012 Ford Mustang throws check engine light and wrench going into "limp mode" (car cuts all acceleration, and just idles). I had to pull to the side of the road, and shut vehicle off. Vehicle returned to normal after one or two turn ons. This will occur every other day, and multiple times in a day. Very dangerous if it was to happen while merging in traffic. This is not covered under Ford powertrain or emissions warranty, they claim that it is an "attachment" to the engine, not a part of it. This issue has caused them to extend their warranties on the Ford escape and Fusion, but not their other vehicles affected by this issue. They have quoted me $700 dollars to completely replace the throttlebody. This is a very dangerous issue, that is linked to more than just the Ford escape and Fusion, and Ford has not given their other vehicles owner's the same warranty.

Upon taking off from a stop light car stalled and lost all engine power. Car started again but stalled just as guiding to breakdown lane on overpass. Had to have car towed to Ford service where they determined it was a bad throttle body. Throttle body was replaced. Ford service spoke of known issues with the throttle body in Focus models but was not aware of any throttle body issues with Mustang.

The contact owns 2012 Ford Mustang. The contact stated the engine light remained illuminated. The vehicle was taken to the dealer and a diagnostic test was performed; which located the failure in the engine block due to premature oil consumption. The engine block was replaced; however, the failure was not corrected. The engine block continued to consume oil prematurely. The manufacturer was made aware of the failure. The failure mileage was 7,000. The current mileage was 11,000.

It was a clear and warm day in southern California. Roads had no dirt, water, debris, etc..I was driving about 35-40 and had just gone in to 4th gear. My 2012 V6 Mustang suddenly swerved to the left really hard forcing me in to the left lane and almost in to another vehicle. Then to the right which almost made me lose control. Felt like each tire was locking up independently. The traction control light was flashing. Felt like I got a flat and that my car was braking all by itself. I tried to throttle up a second later to get out of traffic and it had no response. I could not accelerate when pulling over I hit the brakes and they sounded like metal on metal, felt rough and like the ABS was engaging. Once stopped I checked the tires and all were fine. I turned off the engine and waited a second. Turned it back on and all seems fine. This made me almost crash in to another car!!!! there are a lot of people on forums like this one www.allfordmustangs.com/forums/2011-Mustang-talk/352383-advanctrac-almost-caused-major-wreck-9.html complaining about the same issue.

I had two incidents of unintended acceleration in my 2012 Ford Mustang GT automatic transmission premium pkg. These two incidents occurred on the same day March 5, 2013. The first was after I picked up my car from its garage of several weeks at lunch and drove back to work. I had gone about two blocks from my garage and was braking to slow down to make a right hand turn when the car down shifted and accelerated by itself while I was pressing the brake pedal. I was going about 5 mph when this all started. It lasted for about 3 seconds and then the car released and stopped the acceleration and I was able to slow down and make my right hand turn. I continued on back to work and complained to my co-worker about what had happened and how I was beginning to become afraid of the Mustang. He is my witness about this happening before the second incidence occurred. Later on I left work to go home and on the way home it happened again a second time only this time much stronger. I was in bumper to bumper traffic going under interstate hwy 820 bridge in fort worth to go under the bridge after going through a traffic light on each side to make a left hand turn to get on the West bound IH820. Well because of the traffic you have to stop at one light on the South side of the bridge and then again stop to get through the second light on the North side of the bridge to turn left. Anyway there was a large semi-truck hauling rocks in front of me and I stayed back about 60 feet so as not to get the rocks on new car. He went down to the other light which was red and stopped I was going about 5 mph again and started to brake way back from him because of the rocks and the red light. The car again accelerated on its own while I was pressing the brake pedal. I fought it the whole way but it would not let release till 15 feet from truck. I then crashed. I could have been killed!

The problem with the vehicle started when I tried to start it. When I turned the key the vehicle took a few seconds longer than usual to start up. As I began driving down the highway my vehicle wouldn't shift gears out of 40mph and caused the engine to have high RPM. When I turned off the engine at a gas station and tried to start it back up. Vehicle would not start and I had to get it jumped. Vehicle still doesn't shift gears. This vehicle is only 1 year and 1 month old since I purchased it.

Driving the vehicle in any gear, when gas pedal to the floor, the car will fall on it's face when reaching 3000 RPM's and up at all speeds. It misses and the ti-vct isn't engaging correctly. Oil level is full, and the spark plugs look great. The vehicle will not even throw an mil light. The vehicle drives fine at low RPM's, but once you down shift to go faster it feels like it misfires and the engagement of the ti-vct is coming in and out.
