Open the full vehicle complaint log (all categories)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.
The 2015 Mustang has been driven about 62,000 miles. The car has not been driven excessively in the 8 + years my wife and I have owned it. I recently heard a noise from the car. I brought the car to a local reputable repair shop. They determined, that there was a problem with the differential. They took the housing case off and found metal shreds in the case. They feel that a bearing failed caused the complete differential failure. I talked to Ford and they have no open recalls for this and recommended contacting the NHTSA. The car is at the repair shop waiting for parts to repair the differential at a cost of approximately $3,000.
Weld at clutch pedal assembly broke, causing the clutch pedal to bind. This binding prevents the clutch pedal from fully depressing.
The weld that connects the clutch pedal bar to the tube it pivots in broke on my 2015 Mustang. This makes the pedal wobbly and can prevent the clutch from being fully depressed. For months, the clutch was squeaking. Upon inspection, I noticed the weld was broken. I have not been in an accident because of this, however, the clutch pedal is now loose and can at times hit the 'neutral' switch (which measures full depression of the clutch to allow the car to start), which prevents inconsistent depression of the clutch, leading to unsafe operation.
The contact owns a 2015 Ford Mustang. The contact stated while driving at approximately 45 MPH the vehicle was shifting roughly. The contact stated that no warning light was illuminated. The contact stated that the failure was intermittent but became a recurring failure. The contact stated that the failure occurred at various speeds. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the torque converter needed to be replaced. The vehicle was repaired. The manufacturer was informed of the failure. The contact researched online and related the failure to Technical Service Bulletin Number: 20B27 Torque Converter (Power Train). The failure mileage was approximately 130,000.
Related to Regional Recall 22R01, the rubber bumper on my brake pedal that engages the brake light switch failed and placed the vehicle in a low power mode. This failure occurred while merging onto the interstate and almost resulted in my being rear-ended by a semi truck. Having never been notified of this regional recall, I was able to verify this was the case after searching forums and YouTube and identifying the pieces of the broken bumper in my floorboard. I find it to be HORRENDOUSLY unacceptable that this was allowed to be handled as a regional recall and no notice was ever produced, as it is a safety-related issue that could have resulted in grievous bodily harm. I am located in Kentucky, which is not part of the named region.
The contact owns a 2015 Ford Mustang. The contact stated that while driving at an undisclosed speed and attempting to accelerate, upon the transmission shifting into 4th gear, the tachometer rose 3,000 RPM, after which the vehicle lost motive power and the transmission was unable to shift above 4th gear. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the clutch. The vehicle was not repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA hotline for assistance. The failure mileage was 10,000.

2015 mustang ecoboost premium with performance package. Coolant leaked into the engine oil, causing damage to the engine. Now the engine may have to be rebuilt or replaced.
The welds on the top of the clutch pedal at the pivot point were insufficient from the factory and failed. I was having issues operating the clutch and after doing some research found that this is a common issue and was never covered under any factory warranty. I did not have this inspected at a dealer because I knew it would not be covered. I was able to remove the pedal assembly and repair it and added additional welds myself. I think this is a huge safety concern due to the possibility of the clutch pedal cracking completely and coming loose, which could cause the vehicle to unexpectedly engage the clutch and run someone over or cause a collision. I have photos of the damaged components. It took me a total of 8 hours to complete the repairs. I am also concerned about the quality of the steel used to construct the pedal as it may be too brittle. The OEM should re-design this part and update their manufacturing & welding proceedures.
The contact owns a 2015 Ford Mustang. The contact stated while driving 50 MPH, the vehicle began to vibrate violently. The contact stated that the failure was intermittent at first but had since occurred while driving 50 MPH or faster. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed failures with the center support bearing and drive shaft assembly. The vehicle was not repaired. After investigating the failure, the contact related it to NHTSA Campaign Number: 17V408000 (Power Train) but the VIN was not included. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was 99,000.
THE CLUTCH PEDAL OF MY MUSTANG FAILED AT JUST OVER 90,000 MILES. I WAS DRIVING IN MY NEIGHBORHOOD WHEN THE PEDAL WAS NO LONGER ABLE TO BE OPERATED SAFELY AND REQUIRED TWISTING MY LEG IN ORDER TO PUSH THE PEDAL DOWN. AFTER LIMPING THE VEHICLE HOME, I INSPECTED THE PEDAL AND FOUND THAT WELD THAT JOINED ONE SIDE OF THE PEDAL ARM TO THE PIVOT BAR HAD BROKEN OFF COMPLETELY, AND THE OTHER SIDE HAD CRACKED. THIS ALLOWED SIGNIFICANT LATERAL MOVEMENT OF THE PEDAL, WHICH CAUSED IT TO HANG UP IN THE ASSEMBLY WHEN PUSHING IT IN. THERE WAS NO ABUSE LOADING OF THE PEDAL THROUGH THE LIFE OF THE CAR. AS A MECHANICAL ENGINEER, I CAN SAY WITH CONFIDENCE THAT THE WELD THAT BROKE OFF WAS BAD/COLD, AND THAT ONCE IT BROKE, SHIFTED ALL THE PEDAL LOADS TO THE OTHER SIDE, RESULTING IN ITS FAILURE. THIS DESIGN IS NOT ROBUST TO TYPICAL MANUFACTURING QUALITY VARIATIONS DUE TO THE WELDS BEING ONLY 90 DEG AROUND THE CIRCUMFERENCE. MY FAILURE IS ONLY ONE OF DOZENS THAT HAVE BEEN REPORTED IN MODEL SPECIFIC FORUMS AND ON SOCIAL MEDIA. I HAVE ENCOURAGED OTHERS WITH THIS ISSUE TO REPORT THEIRS.
THE MANUAL TRANSMISSION IS FAULTY, GOT IT REPLACED UNDER WARRANTY AND NOW AGAIN WENT BAD BUT NO MORE WARRANTY. THE AC COMPRESSOR WENT OUT AND EVAPORATOR CORE IS BAD(VERY COMMON PROBLEM WITH 15-17 MODELS), IT CAUSES WINDSHIELD TO FOG UP BAD AND CAN BARELY SEE AT TIMES WHEN DRIVING, VERY EXPENSIVE TO FIX TOO.

THE GETRAG MT-82 TRANSMISSION LOCKS ME OUT OF 2ND GEAR WHEN IM ACCELERATING HARDLY FOR EX. MERGING ON THE HIGHWAY. ALSO MY MUSTANG IS PLAGUED WITH ELECTRICAL ISSUES RANGING FROM CONNECTING WITH BLUETOOTH, INOPERABLE BACKUP CAMERA, TAG LIGHT WIRE STRIPPED. SOMETIMES WHEN I START MY VEHICLE, BLUETOOTH WILL NOT CONNECT TO MY PHONE FOR REASONS I DONT KNOW. ALSO THE BACKUP CAMERA WORKS 10% OF THE TIME. IVE READ THAT FORDS WIRING IS BEING CRIMPED IN BETWEEN THE TRUNK LID. LASTLY THE REAR TAG LIGHT WIRES HAVE BEEN STRIPPED/CORRODED DUE TO POOR WEATHER PROTECTION.
The ac on my mustang has gone out 3 times causing my windshield to fog up and making it very hard to see through. From my understanding Ford already knows about this problem and the defective ac compressor and evap. I have been having problems with the ac since 20 thousand miles. I also have oil leaking onto my driver side floorboard from a bad master slave cylinder. This also started around 20 thousand miles and Ford did not want to warranty it even though the car was still under manufacture warranty. They said that it doesn’t fall under power tran warranty which does not make sense. This makes it unsafe to drive when your foot becomes slippery from oil. I also have rust all over my hood that Ford did not want to cover under their 5 year paint warranty. Very disappointed by Ford and the low quality product they knowingly put out.
