What owners say about the engine

Verbatim from NHTSA complaints, newest first
“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…”

“I was driving down the highway with heater on and defrost. All of a sudden I hear a pop and my car started bogging down. I exited the highway to get out of danger, it then had a wrench light ( transmission) pop up and when I parked the car on the access road it started smoking a lot. I turned the vehicle off immediately and when I seen smoke coming from under the hood and into the cab of the car. I lifted the hood after seeing fire in the passenger wheel well. And then in the engine block towards the windshield in the middle of the engine. I am a fire fighter and it appeared to me that the fire was being fed by some kind of substance. Fort Worth Fire department showed up and put the fire out and took a report.”

““Charge system service now” came on the dash, battery lost power after about 10 seconds, screen went black, dash went black, car locked up, opened the hood and the engine was on fire, called 911 who came quickly and put the fire out without the entire car burning, insurance later total losses the car. I don’t know if it was the battery or the engine responsible for the failure, because the flames were on the engine and not the battery, but the incident was triggered by a battery warning. I was on the interstate driving 60mph when the car shut off and everything including my headlights and even hazard lights went black. Not only could I have been struck by a car on the interstate, I could have died in a car fire. Because the car locked up, I couldn’t open the trunk or use any electronics. The door could have just as easily locked and trapped us inside a burning car. The car is on a salvage yard, no attempt to replicate has been made. Progressive insurance, and Columbia fire inspected it and found that it was undetermined. “Charge service system now” was the only warning before the infotainment screen shut down to reduce battery usage. Every light on the dash…”

“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.”

“A plastic clip ("Brake Pedal Bumper") broke and fell out of place, causing the brake pedal to no longer reach the brake light switch. The brake lights now remain illuminated permanently, even with the brakes released. This also caused the engine and transmission to go into "limp mode", the engine no longer revving over 2,000 RPM, the transmission not shifting, and hill-start assist and traction control no longer working, making the car unsafe to drive. The brake lights will remain on even when the car is completely shut off and locked, draining and damaging the battery. It is my understanding that this is a known issue, and there was a recall for this in certain states. (Safety Recall 22S02, Regional Recall 22R01). There should be a national recall for this, as the affected part appears to be of low quality, and causes safety issues when it fails, with the car's drivability and lighting affected.”
