What stands out
Owners have filed 28 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA powertrain complaint has been filed on this vehicle in over 5 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 an

The failure pattern owners describe
Owners report two dominant vibration problems on the 2016 Mustang. One is severe driveshaft vibration at highway speeds (60+ mph) that shakes the whole car and blurs the rear-view mirror. Dealers rebalance tires and replace the driveshaft, but the vibration stays. One shop foreman tested four new cars from inventory and found three had the same vibration. Owners suspect a design flaw; Ford customer service told one owner the vibration is "normal" and refused further investigation.
Throttle body failures are frequent and dangerous. The car stalls without warning—at idle, in traffic, or on the highway—and the driver gets a "SEE MANUAL" message with a wrench light. The engine won't restart until manually shifted to Park. A dealer disclosed that 5,000–8,000 units have failed but Ford declined a full-scale recall.
Manual transmission owners report hard shifts, grinding, clunking sounds, and intermittent gear lockout (especially 3rd gear) under all conditions. Automatic transmission owners report harsh, loud clunks from the transmission during acceleration from a stop. Multiple dealers tried repairs over weeks without success, then told customers the behavior is "normal." Owners also report sudden power loss on the highway, transmission overheat codes, clutch pedal welds breaking, and purge valve failure causing engine stall—issues Ford has recognized internally but not fully recalled or repaired.

Failure modes owners describe
Driveshaft vibration / drivetrain imbalance
Severe vibration through car at most/highway speeds (60+ mph); persistent after tire rebalance and driveshaft replacement. Owners report blurred rear-view mirror, vibration felt throughout cabin. One complaint notes vibration may be causing differential seal leakage. Shop foreman tested 4 new cars and found 3 had the vibration defect.
When: Early ownership, under 500–few thousand miles in some cases; complaint #1 describes ongoing issue; complaint #9 under 500 miles
Symptoms owners cite: Severe vibration at highway speeds (60+ mph); Vibration felt through steering wheel and cabin; Blurred rear-view mirror; Vibration persists after tire rebalance; Differential seal leakage (attributed to vibration)
Repairs/costs cited: Tire rebalance, driveshaft replacement (twice in one case with re-indexing of second shaft); vibration persists after repairs
Recalls/TSBs owners mention: Dealer told customer vibration is 'normal' and no repair needed; refused to investigate further
Throttle body failure
Electronic throttle body stops responding or vehicle stalls without warning. Customers receive 'SEE MANUAL' message and wrench warning light. Car loses all power and cannot be restarted until shifted to Park and restarted manually. Occurs at various speeds and operating conditions (parking lot, rush-hour traffic, highway 65 mph, uphill at 40 mph). Complaint #17 states that dealer informed customer that 5,000–8,000 units have failed but Ford declined full-scale recall.
When: As early as 6 months, under 8,000 miles; also seen at 5,000 miles or less
Symptoms owners cite: Vehicle stalls without warning; Loss of all power and acceleration; Wrench indicator and 'SEE MANUAL' message; Engine will not restart until manually shifted to Park; Check engine light may appear
Repairs/costs cited: New throttle body replacement required
Recalls/TSBs owners mention: Dealer confirmed faulty throttle bodies from factory are known issue; Ford declined full recall despite 5,000–8,000 known failures
Manual transmission hard shifting, clunking, and lockout
Hard-to-engage gears with grinding, clunking, or knocking sounds when shifting or accelerating from stop. Intermittent lockout of gears (especially 3rd gear) during acceleration or normal shifting. Clunking in lower gears (1st–4th). Occurs under all driving conditions and when stationary. Multiple owners report this is widespread across 2015–2017 Mustangs; Ford dismisses as 'normal behavior' after attempted repairs fail to resolve.
When: Early ownership; as few as 300 miles or under 2,000 miles; intermittent throughout ownership
Symptoms owners cite: Hard to shift, grinding noise; Loud thumping when engaging gears; Clunking or knocking sounds from transmission; Locked out of specific gear during acceleration; Difficulty engaging 1st–4th gears; Gear clash during shifting despite proper clutch disengagement; Jerking and hesitation at low RPMs
Repairs/costs cited: Transmission servicing attempted (parts removed and serviced); problem recurs immediately after repair. Ford refuses to address underlying cause.
Recalls/TSBs owners mention: Dealer told customer this is 'normal behavior'; Ford tells customers clunking is normal after repair attempts fail
Automatic transmission shift harshness and clunking
Loud clunking or harsh engagement from automatic transmission, especially when accelerating from a standstill. Appears very early in vehicle life and persists despite multiple dealer visits. Complaint #19 required 3 dealer visits over one month with no resolution; Ford then declared clunking 'normal.'
When: As early as 4,500 miles on new vehicle
Symptoms owners cite: Loud clunk when shifting; Harsh engagement when accelerating from stop; Clunking in rear of car
Repairs/costs cited: Attempted repair over 3+ visits spanning over one month; problem remains
Recalls/TSBs owners mention: Ford declared clunking 'normal' behavior after failed repair attempts
Transmission power loss and limp mode
Sudden loss of acceleration and power, often accompanied by 'Vehicle Not in Park' message, check engine light, or wrench indicator. Transmission may also enter reduced-power 'limp mode' due to overheating. Engine power and RPM are computer-controlled and reduced when transmission reaches critical temperature.
When: Complaint #6 at unspecified mileage; #7 at 112,000 miles; #18 not specified
Symptoms owners cite: Sudden loss of power and acceleration; Vehicle will only move at 10 mph with engine power; Gas pedal does not control motor speed; 'Vehicle Not in Park' message displayed; Wrench indicator light; Check engine light; Transmission overheat codes on scan
Codes mentioned: Transmission overheat codes (complaint #18)
Repairs/costs cited: Transmission lead frame replacement (complaint #7); repairs may address power loss temporarily
Transmission output sensor failure
Transmission loses engagement and goes into neutral while driving on highway, caused by failed output sensor.
When: Unspecified mileage
Symptoms owners cite: Transmission shifts to neutral while driving; Loss of power while on highway
Codes mentioned: Bad transmission output sensor
Clutch pedal assembly failure
Welds on clutch pedal assembly break away from housing, making transmission impossible to disengage. Customer forced to use brakes to stall vehicle.
When: Unspecified mileage
Symptoms owners cite: Clutch pedal fails; Inability to disengage transmission; Welds break away from clutch housing
Repairs/costs cited: Replacement part unavailable; shop welded pedal back to assembly as temporary fix
Purge valve failure
Evaporative emission control (purge) valve fails repeatedly, causing engine stall on roadways. Complaint #2 documents replacement in 2017 and again in 2021 or 2022 following engine rebuild under powertrain warranty. This is a known issue on online forums and open recall for 2018–2019 model years. Dealer stated fault codes trigger Ford instruction to replace for free, indicating Ford awareness of the defect.
When: First replacement in 2017; second in 2021 or 2022 (complaint filed for 2016 Mustang)
Symptoms owners cite: Engine stalls on busy road; Faulty purge valve
Codes mentioned: Specific fault codes unknown; owner states dealer given sequence of codes
Repairs/costs cited: Valve replaced in 2017; replaced again in 2021/2022 as part of total engine rebuild under powertrain warranty
Recalls/TSBs owners mention: Ford has issued open recall for 2018–2019 models; dealer instructed to replace for free if specific codes present; conflicting information given on emissions warranty coverage
