2015 Ford Mustang Powertrain (other) Problems

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.

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.

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.

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 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 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.

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.
