I took my 2016 Ford Mustang into the dealership 3 times since January 8th to diagnose the reason for the continuous and random stall out. The car would just turn off randomly for no reason.

First they thought the remote was not detecting the car and therefore the remote key was faulty.. it was replaced and 4 days later it stalled out again and it costs me $225 dollars to fix and $400 to rent a car. The 2nd time I took it, the dealership replaced the instrument cluster and it cost $900.00 to replace and $250 bucks in rental. The car stalled out again 4 days later. I went to Ford and I was furious, this time they figured out it was the purge valve which was defective and therefore my car was not appropriately registering fuel. Ford did not charge me but I had to get a rental $150.00. I am hoping this resolved the matter.

Everyone if you have a Ford Mustang 2016, and the car is stalling, please check the purge valve system. It took Ford 6 weeks to figure this out. I almost had a car accident because of this stalling issue.

I am hoping everything is resolved now, but basically I have a new car now.

Purchased 2016 Mustang GT Automatic with 8000 miles used. On the first drive home, the engine stalls when coming to a stop and continues to do so on a regular basis as long as the automatic is in "Drive" and not "Sport". Dealer employee drove it home over weekend and verified fault.

Dealer then claimed that previous owner removed the Sound Resonator (FR3Z-9P437-F), and implied over the phone that was causing the problem, and that they would need to charge me $540.

At the same time, they said they also replaced purge valve (AU5Z-9C915-B) because they detected a leak, and that would be replaced under warranty.

On the documentation, the phone implication as to the cause of the problem was left out. I'm guessing they spent a lot of time on diagnosing the problem and needed to recoup some of the labor since the resonator was only $86.

So you tell me - is there any way for removal of the Sound Resonator to cause the engine to stall when coming to a stop? Versus a leaking purge valve? I have no idea whether the Sound Resonator really was actually removed by the previous owner, but it doesn't sound plausible that it was causing the problem. I probably made the mistake of telling them I bought it used. As many have pointed out, dealers will try to get out of warranty repairs if they can show even the slightest aftermarket modification. Can't prove they shafted me out of $540, but....

Specific wording on invoice: "Removed the evap purge hose and found purge valve leaking. Performed evap static test failed perf evap leak test found purge valve leaking. Racked vehicle and insp evap canister no signs of fuel in it. Installed a new purge valve and perf evap retest passed."

Note: They did NOT say what caused the stall in the wording of the invoice. Clever or imprecise? I'm guessing the former.

While driving on the freeway at a speed of 75 mph the car stalled and lost all acceleration power. The dashboard flashed a wrench warning sign with instructions to see manual. I pulled the car over to the shoulder and it continue rattle and shake. I turned off the engine and waited a minute and restarted the car which appear to have reset the car and it was good to drive for the next 75 miles. The car was fine for the next two days and then it did it again while driving on the streets and once again turned off the engine and the car was fine again. Drove the car to work a commute of 25 miles and the car worked fine. But, that evening driving back home the car stalled;however, this time the check engine warning sign stayed on. Drove the car to the dealer the next morning which there appears to be a software update to correct the problem with the body throttle.

Purchased new 2016 Ford Mustang in April. I was driving uphill at 40 MPH. All of the sudden the engine cut off. The power was still on -I had lights, Air, and radio on and they kept working. When the engine went off a large wrench came up on the display and it said see manual.

There was no place to pull over and there was a line of traffic behind me that wasn't very happy. I tried pressing the Start button but it would not start. I had to come to a complete stop, put the car in Park and then was able to restart it. I made it home.

If this would happen to me on the beltway or I-95 I could get killed. The car didn't overheat and all the gauges showed normal. Is there any type of recall going on with this? I bought a 2005 Mustang brand new and had it for 11 years and had no problems with it.

You would think in this day and age that they could build a car where the engine doesn't shut down while driving. Scared the crap out of me.
