What stands out
No new NHTSA powertrain complaint has been filed on this vehicle in over 7 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
During service and repair requiring removal and replacement of a crankshaft bolt and/or crankshaft damper, achieving proper torque of the crankshaft pulley bolt is critical. Incorrect torque may allow the bolt to loosen resulting in the timing gear breaking and engine damage. Replacement of the bolt is critical to the repair and accurately following the installation procedure in the Workshop Manual (WSM) Section, 303-01 is extremely important. The bolt torque procedure can be found in the crankshaft front seal removal and installation procedure or in the engine assembly procedure.
full bulletin at NHTSA ↗Some 2015-2017 Mustang vehicles equipped with 3.7L and 5.0L built on or before 1-Apr-2017 equipped with a 6R80 transmission may exhibit a clunk or ping noise from the driveshaft when shifting from reverse to drive or drive to reverse. A revised driveshaft which has enhanced NVH characteristics has been released. For claiming, use causal part 4R602 and applicable labor operations in section 04 of the service labor time standards (SLTS) manual.

This may be due to small debris causing the VCT solenoid to stick. Before attempting any component diagnosis or replacement of the VCT solenoid, refer to Powertrain Control and Emissions Diagnosis (PC/ED) pinpoint test HK11 to cycle the affected VCT solenoid 10 times to attempt to clear the debris. For claiming, use causal part 6M280 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
full bulletin at NHTSA ↗Some 2015-2019 Mustang GT350/GT350R vehicles may exhibit a hesitation or surge in the vehicle with no diagnostic trouble codes (DTCs) present. This may be accompanied by an inoperative cruise control system. This may be due to a transmission output shaft flange nut that has come loose, allowing the output shaft tone ring to move in relation to the output shaft causing an erroneous signal. To resolve the condition, follow the Service Procedure steps to replace the output shaft flange nut.

The failure pattern owners describe
The 2017 Mustang powertrain has trouble in multiple areas. Automatic transmission owners—particularly those with the 10R60/10R80—complain the transmission gets stuck in Drive or Sport mode and won't shift properly into Park or Neutral, a safety issue. One owner at 94,000 miles found zero transmission fluid and faced a complete replacement. Ford's own TSBs acknowledge the problem stems from PCM/TCM software issues, sticking valves, and solenoid faults, calling for reprogramming and adaptive learning cycles.
Manual transmission owners report the factory clutch fails catastrophically—one owner stranded at 26,000 miles, another stalled in traffic after the clutch separated. Beyond outright failure, shift clunking is common; owners describe audible thumping when engaging into lower gears, especially from a stop, as if something is falling into place. The clutch pedal pivot weld cracks in some cars, forcing the pedal sideways and preventing full sensor engagement, making it difficult or impossible to shift smoothly.
Engine problems are present too. One owner dealt with coolant intrusion starting at 53,000 miles—misfire codes, white smoke, low coolant that won't stay topped off—eventually requiring engine and turbo replacement with only 50% manufacturer coverage. Another case showed an oversized cylinder bore #2 that let coolant flow into the engine at 101,000 miles.
Additional complaints include an oil filter that came loose on a Shelby GT 350, plastic valve covers leaking oil, and a rear differential that failed shortly after other repairs, all with limited or no warranty support.
