2019 Ford Mustang Reliability Score & Common Problems

Owners of the 2019 Ford Mustang report various issues, with common problems including doors unexpectedly opening while driving, backup camera malfunctions, and engine overheating with coolant leaks. Complaints frequently mention symptoms like the passenger door opening on the interstate, backup cameras intermittently failing, and engines emitting excessive steam or smoke due to coolant entering the cylinders. These issues are reported at various mileages, with one complaint involving a crash due to a parking brake disengaging, highlighting potential safety risks. Buyers should be aware of odometer discrepancies and the potential for soy-based wiring attracting rodents, leading to costly repairs.

Owners of the 2019 Ford Mustang frequently report issues related to engine and engine cooling, with a notable pattern of coolant intrusion leading to engine damage. Common symptoms described include white smoke from the exhaust, coolant leaks, and illuminated check engine lights, often accompanied by engine misfires. These issues are typically observed at mileages ranging from approximately 16,600 to 130,000 miles. Some owners also report a ticking sound and RPM drops linked to lifter failures inside the cam phaser. While no crashes or fires are mentioned, the recurring need for engine replacement and persistent drivability problems may concern potential buyers.

Owners of the 2019 Ford Mustang report issues with the steering system, particularly involving power steering failure. Complaints frequently mention the power steering going out, making turning difficult and, in some cases, causing the steering wheel to jerk unexpectedly. One owner reports a crash with minor injuries due to losing control while navigating a curve, suggesting potential safety risks. Another common symptom includes a grinding noise during low-speed maneuvers. These issues appear at various mileages, with one report indicating a failure at approximately 15,000 miles. Potential buyers should be aware of these steering-related problems, as they can lead to loss of vehicle control.

Owners of the 2019 Ford Mustang frequently report issues with doors unexpectedly unlatching while driving. Complaints consistently describe passenger doors partially unlatching and triggering a "door ajar" warning on the dashboard, often requiring the driver to stop and resecure the door. This issue appears to occur at various speeds, with some reports specifying highway speeds between 60mph and 75mph, and others noting occurrences at 20 to 40 mph. Additionally, one complaint highlights a factory defect involving a noticeable gap in the passenger side front bumper under the headlight, which dealerships reportedly attribute to customer damage. The door unlatching poses potential safety risks due to the distraction and uncertainty it causes while driving.

Owners report issues with swollen lug nuts on the 2019 Ford Mustang, making them difficult to remove and potentially hindering tire changes, which poses a safety risk in roadside situations. Complaints frequently mention that dealers replace these swollen lug nuts, with occurrences noted around 54,136 miles. Additionally, one owner describes premature tire wear due to incorrect alignment, which was initially disputed by a dealership due to aftermarket parts but later corrected at another dealership. Another complaint details tire failures, including a blowout and implosion, attributed to external damage like nails and slashing. These issues highlight potential maintenance and safety concerns for prospective buyers, particularly related to the vehicle's wheels and tires.

Owners of the 2019 Ford Mustang frequently report issues with door latches, particularly the passenger side, becoming unlatched while driving. Symptoms include doors slightly opening at high speeds and warning lights indicating a door is ajar. These issues are often described as occurring after driving over bumps or potholes. Complaints mention failure mileages ranging from approximately 35,000 to 144,000 miles. While no crashes or injuries are reported, the potential for doors to open while driving poses a safety concern. This information is particularly relevant for used car buyers considering models with similar mileage.

Owners of the 2019 Ford Mustang report issues with the brake system, particularly a loss of brake responsiveness and automatic emergency braking (AEB) failure. One complaint describes a situation where regular brake pressure failed to stop the vehicle, requiring the driver to apply both feet to the brakes after a warning message appeared. Another owner reports the AEB system does not activate, with dealers unable to diagnose the issue due to the absence of error codes and lack of on-road testing capabilities. These complaints highlight potential safety implications, such as difficulty stopping the vehicle, though no crashes or loss of control have been specifically mentioned. No specific mileage range is indicated, but prospective buyers should be aware of these reported brake system concerns.
