2012 Ford Mustang electrical problems

Filed Feb 8, 2025 · Acceleration, Electrical · FL

Speedometer went to zero while driving and seemed to be in neutral. Could not accelerate. Also low fuel warning light came on when I had a full tank. After car was shut off and restarted speedometer seemed fine for about 1 mile, then self accelerated. Now continues to read zero and can not accelerate unless I restart engine.

Transmission seems to lose power while driving, the car will barely pull itself but the rpms increase if I accelerate. This has happened several times while driving and occasionally there are dash lights lighting and speedometer/gas gauge doesn’t work but that doesn’t happen every time. When it happens I pull over and shut it down and restart and it runs correctly until it happens again! I do a lot of highway driving and the car just “falling flat” on a multi-lane highway at 70+ mph is definitely a safety issue! I have taken it to my local fastlane shop and the car was driven but didn’t malfunction at that time. He advised me to try to drive it there if it happened again, but I have never been close to the shop at the times it happens or they are closed. There is no advance warning, it happens at various speeds and even on takeoff after stopping for traffic lights. I once was pulling into traffic when it happened and didn’t have enough power to get to my lane before it fell flat! Fortunately I could back up before getting hit by oncoming traffic.

I own a 2012 ford mustang and recently had problems with the electronic throttle control. It was the exact same issue as outlined in ford's customer satisfaction program 16b23 (https://ford.oemdtc.com/2670/16b23-electronic-throttle-body-replacement-2011-2012-ford-lincoln/5). I have a 2012 3.7l v6 mustang that I believe should have fallen under this program. I never received any mail or email notifying me of this program, although I had lived at the same address for as long as I had owned the car and previously received an airbag recall notice, so I know ford has my address. I was also at my dealer for service appointments (the same dealer where I bought the car) during the program time period and they never notified me either. Long story short, I just had to pay a little over $400 to have my local ford dealer replace the throttle body. I asked about this program and was told because it was outside of the program end date they couldn't do anything. My question is, why didn't ford contact me about this program if my car was covered? If my car wasn't covered, how did ford distinguish between which cars were worthy of being in the program and which weren't? This was a huge safety issue for me as the car randomly lost power on multiple occasions. One time I was doing 50 MPH on the highway with alot of traffic around me. Luckily there was an open median I could coast into, but I may not have been as fortunate as others who have had this problem. I do not believe ford's customer satisfaction program 16b23 which was only in effect for a year was adequate to address this safety hazard. I also do not believe that ford did their due diligence to notify owners of this program and the associated safety hazard.

Takata recall when I was driving on highway. Several lights on dashboard turned on (airbag, fuel level , wrench light, tire pressure ) and said tire pressure monitor defaulted. After restarted the car, everything works normally. Ford dealer checked the car and said my PCM didn't work. And replaced it for $1000. After several days the problem came again. They did't fix it.

When starting my car, the wrench icon stays lit on my dashboard. The car manual states that this is an issue with the electronic throttle control. The car does not recognize when I am (or not) pushing on the gas pedal- sometimes when I lightly push the pedal, the engine revs, other times the car won't move at all. This has put me (and other drivers on the road) in a very dangerous position to be in, that I can't control my car. I have read many things online that there has been this issue with many other ford/lincoln cars, from 2011-2015. When calling my local dealership, they said they will not fix this issue free of charge, even though ford had a "customer satisfaction program". I was told my car is not in those that had that issue.

While driving on freeway (60mph - 65mph) car suddenly stalls. No power to engine, need to limp to side of freeway (very dangerous). Car sits, then you can re-start. Sounds like electronic thottle body (etb) issue that you are well aware of. Why are you not investigating this issue??? Ford (westway ford, irving, tx) cannot diagnose. This is a critical safety issue. Cars stalling on freeway are a hazard to all parties. You guys need to investigate this issue.
