I bought my 2015 Mustang premium edition with 200 miles on it in 2016. During the last few years, there have been numerous times when the engine has shut off while driving, and stalled twice while waiting at a light. It goes into aux mode. But restarts right away I have not had the problem for quite some time but this past Saturday, it shut down again, while turning and this time a light came on that said run power active. This is a serious and dangerous condition which happens randomly, but usually while turning. Fuel level was 1/4 this past time. Ford must find the cause and recall ASAP. It has never happened while parked to date. Only 6600 miles on the car. Similar reports are posted on this site.
Today I was driving my 2015 Ford Mustang when suddenly the car began to lose speed. The car was slowing down and wouldn't let me accelerate. Eventually while wanting to check if my car was okay I tried to make a left turn into a parking lot and the car engine shut off but the lights and everything were still on. I had to wait awhile and eventually I was able to turn the car back on and safely move into a walmart parking lot.
I have a 17 Mustang gt with manual within the first 1000 miles the engine has automatically turned it self off after getting on a interstate or any time extra power is needed. I would want to stop speeding up I would push the clutch in and put it in 6th and wait for my mph drop to desire speed, during this time is when the engine turns off. I have went to a Ford dealership in richmond, va and they basically said they can't find any issues because their are no codes (the car didn't leave the property). So this issue is a hard to find a fix and most likely won't get fixed till people start getting in accidents or death by accident because of the unpredictable engine shut off.
Car engine shut off completely while disengaging the clutch coming to a stop on busy roads with my child in the car.
Purchased 2015 Mustang 5. 0 with only 6000 miles. And numerous times I tried to register my Mustang with Ford sync vehicle health report but said my vehicle wasnt compadable, which I didnt understand. When I hit 13000miles. . . I noticed vehicle ac was not cooling for a couple days. I made an appointment with dealership but day before I was driving on the freeway checking if maybe the ac would work all of a sudden, the engine shut off. . . . I pushed the clutch back in and started it as I was in neutral. Engine turned back on and I turned off the radio and ac. Thank god I made it back home.
My engine has randomly shut off three separate times now. I have about 12,000 miles on mt 2015 Mustang gt w/pp manual transmission. The first time I was parked and it was idling, my friend and I both witnessed the idle dip, then 3-5 seconds later the engine shut off. The second time (was much more dangerous) I was changing lanes because of a car fast approaching from behind, I downshifted from 3rd to 2nd gear (30-40mph), let out the clutch smoothly, pressed the accelerator and the car did nothing, I looked down and the rpm was at 0 and "press clutch to start" was displayed on the gauge cluster screen. I quickly depressed clutch and restarted engine and took off to avoid an accident. The third time happened today 3/15/2016 I was again at idle and the engine just shut down without me touching anything, it again displayed "press clutch to start". I've read in forums that many people are having this issue intermittently, this could be a serious safety issue that can have deadly consequences. Please address this issue correctly rather than sending everyone home with the "we didn't find any issue" go-to response. Hopefully people don't have to get injured, or god forbid die, before this issue is taken seriously.
With only 500+ miles on my car to date, I have experienced multiple occaisions where my 2015 Mustang gt's engine shuts off without warning when I am approaching a stop and disengage the manual transmission to coast to a stop. The car does not give any indication that it is experiencing any issues prior to or during the shutdown. The engine simply dies. This latest incident nearly caused an accident because when I was approaching the red light I put the car in neutral while slowing down and the light subsequently changed quickly to green--and my engine died. The car behind me had already accelerated expecting me to proceed but I was coasting while trying to restart the car. Fortunately, there was no rear end impact and I restarted the car and proceeded. This is a serious safety issue and what makes it worse is how random it is. Ford needs to figure this out quick before somebody gets hurt or killed in an accident related to this issue. For the record, there are many others with this same model car that are experiencing the same dangerous issue and are posting their experiences online at the Mustang generation 6 forum.
Vehicle just dies (engine shuts off) with the clutch in while slowing to a stop. Could possibly cause an accident.
