2015 Ford Mustang: engine stalls while driving

Filed Jul 26, 2026 · Electrical, Engine · GA

I am filing a formal safety complaint regarding a catastrophic Electronic Power Assisted Steering (EPAS) failure and severe electrical short circuit on my 2015 Ford Mustang. This vehicle is exhibiting hard fault code B137F:09 (Steering Wheel Left Switch Pack: Component Failure / Short to Ground or Open). This electronic failure creates an immediate, severe safety hazard that goes entirely outside the scope of normal vehicle wear and tear. While driving, the vehicle's steering wheel pulls and jerks violently on its own, actively fighting my manual steering inputs. Furthermore, this internal electronic short creates a massive parasitic electrical draw that prevents the vehicle's computer modules from entering sleep mode when turned off. This has resulted in the primary vehicle battery draining completely flat and causing the vehicle to completely shut down, stall, or lose total electrical power altogether. A vehicle that forcefully steers itself away from the intended path of travel and suffers total electrical shutdown is a clear, life-threatening safety risk to myself and others on the road. Ford Motor Company is fully aware of this dangerous defect. They previously issued Safety Recall 15S18 for a very specific, limited batch of early-production 2015 Mustangs experiencing identical EPAS failures, replacing their steering gears for free. For the remaining 2015 Mustang owners experiencing the exact same hazardous failure, Ford quietly shifted the issue over to a Technical Service Bulletin (TSB / SSM 51312). By limiting the scope of Recall 15S18 purely due to the financial cost of a universal recall, Ford has left an entire population of 2015 Mustang owners in direct harm's way. Some owners received a free lifetime safety fix, while the rest of us are being forced to pay thousands of dollars out-of-pocket to correct an identical factory electronic defect. I request that the federal safety agency immediately open an investigation into Ford's handling of the 2015 Mustang EPAS and more.

The evaporator is leaking and apparently is a known issue from ford and they didn't report this. The evaporator core is leaking and it blows hot air for a good amount. It draws a lot of power form the system and drops the rpm below idling. Forcing me to rev a cold engine so that it does not stall out.

Indicator light check engine with fluctuating or inaccurate fuel levels. This could lead to a stall while driving and/or an inability to restart the vehicle, which can increase the risk of a crash.

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.

Brake lights would not shut off and stayed on steady so people behind could not tell whether or not I was braking ....when driving car would drop speed for no apparent reason like it was going to stall out. I found small plastic debrie on floor mat I guess it was a washer type thing from brake switch brittle and broken is pieces? This all happened while driving.

For the past three years. When I go to work. Everything is fine. When I leave work. I back the car up about 15-30 feet. Then pull out of the parking lot. When I pull out. As I press the gas & start going faster. The car stalls, jerks as if the breaks are pushed, then starts driving as normal again. It happens all the time. But my ford place says it has to do it with them driving for them to know what to do or what the issue is. Then this past week. The same thing happened. But it happened for a longer time and the traction control light brinked the whole time I was trying to accelerate. So a friend at a ford body shop told me it was probably my ABS sensor. Also the hood of my car started to loose paint for no reason. No rust. It's just flaking off. The flacking started near the headlight underneath the top of the hood. & is slowly coming towards the top of the hood. My 36,000 mile warranty just expired right after I noticed the issue. And they wouldn't cover it. I don't think that's right!

Bought a 2015 mustang gt feb 28 at 9pm with 19200 miles on it. March 1 I noticed the car had 3 different tires brands on it. The car pulls bad to the left under acceleration, when you let off the gas it pulls right. Laurel ford did a 4 wheel alignment on the car and it still pulls. Now they say it is the struts and the orded 2 new ones for the frount. I think it is the tires not the struts but they won't replace the tires because they would haft to pay for them. They only want to replace parts that warranty will pay for. They said no way they would pay for 4 new tires. This is a safety issue ⚠️ very dangerous driving the car because it is a manuel transmisaion and every time you accelerate the car pulls left holding the wheel straight does not stop it, it still pulls left, then right when you take your foot off the gas. What ford dealer would sell a car with 19,200 miles on it with 3 mis mached tires on it. Also the tires have different load and speed rateings on each one, like 101y, and 105y, and 100 y. I dont know wats wrong, I think laurel ford is stalling, why???? I have had the car for 15 days now still not fixed. I guess some one will look into this after some bodys gets killed like me and what ever car I hit head on at 70 MPH.

2015 ford mustang gt premium with performance pack and all options. The car has 28000 miles and I purchased it april 15, 2015. At that time it had a little over 26000 miles. The following is what's happening. May 4, 2017 I heard a popping noise coming from the clutch pedal while driving to work. It did it during the day so I pulled the vehicle into my shop to look at the clutch pedal to see where the noise was coming from. The link from the clutch master cylinder to the pedal was lose and making a popping noise. I re secured the link by pressing the rod back onto the pedal. Saturday may 6, 2017 at 11:12 am the noise came back and while driving I pushed the pedal fast four times and the link came lose while driving. I coasted to a stop and look at the pedal again and saw that the master cylinder push rod came completely off. I reconnected it and before I continue driving the car contacted courtesy ford in conyers, ga and set up an appointment monday may 8, 2017 at 7 am. Also doing this time the vehicle cut off several times. It happens when I'm sitting at a light and the vehicle is idling, coasting in neutral, coming to a stop, turning. The vehicle has cut off at least 11 times and I have documented it. Also I recorded two videos with my phone. After the vehicle continued to stall, I decided to park the vehicle for the week end and plan to take it to the ford dealer for these and other problems.

Engine stalls during idle at stop signs and stop lights and also stalls during initial acceleration under 10 MPH. This has happened at least 25 times over the past year. There are no fault indications on the dash. I place sifter back in "park" and engine restarts until the next time it stalls. There is no prior indication of any kind that the engine is about to stall. The engine simply shuts off. Have taken the car to the dealer to determine the cause twice. They cannot determine the cause so make no attempt to do any component replacements. I contacted ford motor customer relations and they started a case file on this, cas-12064085. I have expressed my concern over and over again that my car may stall at the wrong place at the wrong time and possibly cause a collision. Both the dealer and ford motor company seemed "totally" disinterested. All they say is "sorry we cannot help you".
