What owners say about the power train

Verbatim from NHTSA complaints, newest first
“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 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.”

“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.”
