Electrical system

68 reports3 crashes2 fires
“While driving my 2015 Ford Mustang at low speed on a city road, I attempted to activate the hazard warning lights. Because the engine Start/Stop button is located close to the hazard light controls, I accidentally pressed the ignition button instead. I pressed the button only briefly, without holding it down or pressing it multiple times. The engine immediately shut off while the vehicle was still moving. This presents a serious safety concern because an inadvertent, momentary button press can disable the engine during normal driving, potentially reducing steering and braking assistance and increasing the risk of a collision. I believe the placement of the ignition button and the system's response to a brief accidental press warrant a safety investigation.”

Engine

51 reports3 fires
“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…”

Service brakes

46 reports5 crashes
“While driving, I attempted to depress my clutch pedal in order to bring my vehicle to a stop. My clutch pedal only went halfway to the floor. I was able to force it down to the floor using a higher than usual amount of force. After bringing my vehicle to a stop I inspected my clutch pedal and found that it had side to side play resulting from a cracked weld where the clutch pedal was welded to a shaft on the clutch/brake pedal assembly. Upon further research online I discovered that other owners of similarly aged mustangs have had identical issues to what happened to me.”

Structure

“My passenger door latch pops open nearly every time I drive on the highway. The latches were previously the subject of Safety Recall 16S30. I had my vehicle inspected by a Ford Dealership. No repairs or work was deemed necessary at that time. In the years since, my door now comes unlatched. Infrequently at first and now with very alarming frequency. Safety Recall 20S30 was issued specifically to address these inspections and recalls being completed ineffectually. Somehow my VIN has been left off of this recall even though it was on the 2016 one. The dealership is trying to charge me nearly $2000 to fix a known safety issue. This seems unreasonable, unfair, and extremely dangerous.”

“Clutch assembly failed, the metal bracket weld cracked/failed resulting in the clutch pedal being inoperable. It's not available for inspection since I had it replaced and the defective assembly disposed of. My safety was at risk since I had extreme difficulty shifting gears on the road. The issue was confirmed at an independent service center - AAMCO of Huntsville, AL. No other entity inspected the part. The vehicle gave me no warning or indication of a problem other than the difficulty with starting and operating it.”

Exterior lighting

42 reports
“The contact owns a 2015 Ford Mustang. The contact stated that before making a left turn the contact switched on the left turn light signal; however, upon making the left turn the contact noticed that the left turn signal on the instrument panel was flashing twice as fast as normal. The contact pulled over to inspect the vehicle. The contact became aware that the taillights were inoperable; however, after restarting the vehicle, the taillights became operable. The following day the contact drove to a local dealer where the vehicle was inspected; however, the vehicle was not diagnosed. The contact was informed that the vehicle needed to be diagnosed to determine the cause of the failure. The contact was made aware of SSM: 10144218 and linked it to the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 82,000.”
