Question Need and would appreciate some help with my 2014 GT!

Hey guys. I need some help so badly and know this the place to turn to. My 2014 GT with the track pack is having a big problem. It only has 1,600 miles . It is a manual and 5-6 times now when I really stomp on the gas, the car totally loses power. I have to let off of the gas for the car to regain normal response. One time when this problem happened, I decided to keep the gas pedal floored to see what would happen. The entire instrument panel started flashing and the car almost stalled, that is until I let off of the gas. I have brought it to the dealership and they tell me their technician can't find anything wrong. They give me the whole "maybe you are missing shifts" nonsense. I explained to them that this problem happens when I am in gear, not from shift to shift. I'm so bummed. I special ordered this car and it took 3 months to arrive. The car has also already been to the dealer for an oil leak. Brand new car that leaked oil from the crankshaft all over my driveway and garage. It's just been such a bad experience. Stinks, because when the car is running right, there's nothing like it! Can someone please help me to know what I need to tell the dealer to check that they are missing? I don't want to give up on my car! I saved for years to get it. Any help would be incredibly appreciated. Thank you.

I am thinking you have a problem with your throttle body. Does it only happen intermittently?

Hey Deerslayer. Thanks so much for your response. The mechanic at Ford thought it might be the fuel line, but I think you are probably closer. And yes the problem is very intermittent. It only happens when I am driving normally and decide to hammer it. One example is I was revving about three and a half in 3rd and stomped on it. The car started to take off and then bogged out completely to the point where entire instrument panel started flashing. But whenever this problem has happened it stops immediately if I left off of the gas pedal. Airflow? Thanks so much.

There is a TSB for the front crankshaft o-ring. That could be your problem. You may also need a crank relearn.

If it continues to happen, go back to the dealer, and insist that either the service manager or a mechanic go with you on a short test drive. Usually these dealerships have enough empty parking lot space for you to demonstrate the issue. If it only happens while you are in 3rd gear and "stomp it", then get it out to a road that allows you to demonstrate this.

Again, get one of them to go with you on a test drive.

Are you sure this isn't just the grannies kicking in? Tc and stabilitrac?

Just brainstorming here so...

If your gauges start flashing, my first guess would be something electrical.

I would think that if it were a fuel/air issue you would trip a CEL.

Could be a vacuum line off. However this should trip a CEL as well.

My brother is a mechanic for a VW dealership. He is the guy that lives the furthest from work. When problems like this arise, he often takes the customer's car home for the night, and they get a loaner.

Thanks for your time GrabberBlue. I will definitely mention what you said to the rep at the dealer. Ironically it was the rear crankshaft that had the oil leak.

Thanks Bucko. I suggested that to the service technician and he agreed to go out with me on a ride. So I will be doing that tomorrow about 1 p.m. Pacific. Thank you so much for the advice!

Thanks for your input Skulls. That was my initial feeling as well, that it must have something to do with spark or something. I really appreciate you brainstorming with me. A technician at Ford told me he took the car out for half an hour and didn't have anything unusual occur. It's frustrating you now? Because I know the car is doing what it's doing but the people at Ford are acting like I'm some idiot that doesn't know how to drive.

Hey there. Thanks for your time, I don't think that it is the traction control or stabilitrac because I have pushed the car hard enough to have it break loose. And it didnt bog out like it has several times when I am just on a straight away and stomp on the gas.

I would try to duplicate again than I would turn off traction control and try to make to happen again just a little test you can do on your own.

First thing that came to mind for me as well. The nannies in these cars are exceedingly effective at neutering your power if it feels you are being unsafe.

I used to have issues when I was going WOT, but that was before I got into the habit of turning off the advancetrak and traction control each time I started her. Hold the brake, press the TC button for like 5 seconds, wait for the gauge to tell you advancetrak is off....then go have some fun.

I'm not sure where I'd start if it turns out to me mechanical

Thanks Stew. I will definitely give that a shot and feel stupid that I didn't think to try that already. Thank you very much. You guys have all been so cool

Thank you Rynarok! Excellent advice. I really appreciate your time and everyone's time in helping me out with this issue. This forum is awesome! Motivates me even further to get this car dialed in perfectly and be more of a participant in this forum. You guys are great!!

Did you have the rear crankshaft oil leak fixed? If so they removed the clutch and they didn't do the crankshaft relearn. That would be my guess.

Mine was doing that when I first got it last month. I'd lose power, CEL would start flashing, and the get-home mode wrench even turned on a few times. But, there were no codes stored. Fortunately, there's a TSB to put a spacer on the crankshaft or cam position sensor to make that go away. They installed the spacer and haven't had a problem since.

But if all your gauges really are flashing (blinking??), then it sounds more electrical than anything. Get someone to film the event with a camera phone.

Wow Bryan! Your experience sounds exactly like mine. I rode with the technician yesterday at length and we were unable to duplicate the problem. However when we were finished driving the car we noticed there was oil pooling on the rear right rim. It turns out the car now has a second documented oil leak. This one is from the rear axle. I have had this car since September 14th and it has now been at the dealership due to problems for 21 days and counting. I no longer want the car and will be pursuing the California lemon law as soon as the lawyers office that specializes in these problems opens tomorrow. An unbelievably disappointing experience. The people in Flat Rock that assembled this car should be ashamed of themselves. But the mustang people in this forum have been the best and I truly appreciate you all.
