The 2017 Ford Mustang GT is generally reliable, but owners report a handful of recurring issues. The most frequently mentioned problems fall into four areas: infotainment/electrical glitches, transmission behavior, occasional engine oil consumption or noises, and general recalls/maintenance matters. Checking for open recalls and a solid maintenance history is advised when evaluating a used example.
Infotainment and electrical system issues
Many reports center on the car’s tech interface and electrical components, which can affect daily usability and safety features. Below are the issues most commonly cited by owners.
- MyFordTouch/Sync infotainment glitches: touchscreen freezing, unresponsive controls, laggy menus, or unexpected reboots.
- Bluetooth pairing and connectivity problems: dropped connections, unstable hands-free calling, or audio dropouts.
- USB/CarPlay/Android Auto issues: devices not recognized, intermittent audio routing, or delayed charging.
- Display or gauge cluster quirks: dimming screens, flickering displays, or intermittent instrument readouts.
These electrical and infotainment quirks are typically addressed with software updates or dealer reflash, though persistent issues may require more involved repairs or replacement parts.
Transmission and drivetrain concerns
The GT’s available transmissions—the automatic 6R80 or the manual Tremec setup—have produced a few reports of uneven behavior, especially under certain driving conditions. Here is what buyers and owners often mention.
- Automatic transmission shifting quirks: hesitations, abrupt or slow shifts, particularly at light throttle or cold start, which can sometimes be improved with software updates.
- Torque converter shudder or low‑speed surging: a noticeable bump or shudder during light acceleration or deceleration, sometimes addressed through service bulletins or fluid changes.
- Manual shifter or clutch issues (if equipped): occasional difficulty finding gears or crunchy shifts due to wear in linkage or hydraulic clutch components.
If a used GT exhibits unusual shifting behavior, a dealer inspection is recommended to verify firmware status and rule out hardware faults.
Engine performance and reliability
The 5.0 Coyote V8 in the GT is known for strong performance, but a subset of owners reports engine-related concerns that can impact reliability or ownership costs. The typical issues mentioned are listed below.
- Oil consumption in some engines: a small number of cars reportedly burn more oil than expected, necessitating periodic top-ups or dealership checks.
- Lifter tick or occasional cam phaser noise: subtle noises at startup or low RPM that may require inspection or calibration in some units.
- Cooling system quirks: rare cases of thermostat or cooling component anomalies affecting temperature management, usually under heavy driving or high heat.
Most 2017 GT engines perform capably with regular maintenance; unusual noises or rapid oil loss should be checked under warranty or through a service bulletin.
Recalls and maintenance considerations
Recalls and service campaigns can affect any model year, so verifying a vehicle’s recall status is essential before purchase or ownership. Here are the key points to consider.
- VIN-based recalls: some 2015–2017 Mustangs have had recalls related to safety or emissions systems; confirm with the NHTSA recall database or Ford.
- Software updates: dealers frequently issue ECU/TCU updates to address intermittent glitches in infotainment or powertrain control modules.
- Routine maintenance emphasis: timely oil changes, brake inspections, and coolant service are important to long-term reliability, particularly for high‑performance braking and cooling systems.
A vehicle with completed recalls and up-to-date software is typically more dependable; always verify recall work has been performed on the specific VIN.
What to check when buying a used 2017 Mustang GT
If you’re shopping for a used 2017 GT, focus on the car’s electronics history, transmission behavior, and maintenance records. A thorough pre-purchase inspection can catch issues early.
- Test infotainment and controls: ensure the touchscreen responds smoothly, CarPlay/Android Auto is functional if equipped, and the radio and climate controls operate reliably.
- Test both transmissions: drive in sport modes and observe shifting behavior, throttle response, and any shudder or hesitation; verify firmware is up to date.
- Check recalls and service history: confirm all recalls were addressed and review maintenance records for oil changes, coolant flushes, and brake service.
With careful inspection and a clean service history, a well-maintained 2017 GT can deliver strong performance and a satisfying ownership experience.
Summary
In brief, the 2017 Mustang GT’s most commonly reported issues cluster around infotainment/electrical glitches, transmission behavior, and occasional engine oil consumption or noises. Recalls and software updates play a significant role in reliability, so verifying recall status and ensuring up-to-date updates is crucial. A thorough pre-purchase inspection and documented service history are the best safeguards for a trouble-free ownership experience.
