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.

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 Ford wiring is being crimped in between the trunk lid. Lastly the rear tag light wires have been stripped/corroded due to poor weather protection.
