2019 Ford Mustang Problems

2019 Ford Mustang with 3.2 EcoBoost engine has coolant intrusion into the engine thru a defectively made engine block. Diagnosed by the Ford dealer in Hinesville,GA on August 11,2026. Car has 52,731 miles on it and has always been maintained by the local Ford service department. Car is a daily driver, no abuse or rough driving. Car is available for inspection upon request Coolant intrusion can cause sudden engine failure, loss of power and sudden stoppage at any speed. Overheating due to loss of coolant, engine fire, loss of control of the car. Check engine light came on and engine ran rough on cold start up on [XXX] & i then took it in to be checked out by Ford service. Service advisor stated that this coolant intrusion is due to a Ford known defect in the EcoBoost engines; but that there has been no recall. Only solution he offered was to have a new replacement engine installed for about $13,500. I declined the replacement.

Engine Failure where a replacement engine is required just after a few months of purchasing the vehicle.

The rear backup camera on my 2019 Ford Mustang intermittently stops working. At times the screen shows a blue screen or displays a “backup camera not available” message. The issue comes and goes without warning. This creates a safety concern when reversing, as visibility is reduced and the camera cannot be relied upon. The problem appears to be electrical and is not consistently functioning.

Refused to fix the issue because the OBD reader did not provide any codes OBD reader is not sending any signals, but there is power I called Sam’s Ford to send a service to fix the recall but told me they will not fix the issues because no codes were being provided And the check engine light is active

Rebuilt transmissions are bad. Two in the last four weeks have been placed in my 2019 California Special Edition Mustang, and both are bad. They both came from the Ford manufacturer. The transmission locks up at any point while driving at any speed, causing the car to jerk to a standstill, and only while you are driving. We were on 465, and the car automatically stopped in the middle of the highway while other vehicles were flying by and behind me. We were almost hit by several vehicles. This also occurred while the mechanic test drove the car with the second rebuilt transmission placed in my car. No warnings, nothing before this occurred. This is a huge safety hazard and risk for many. The dealership is aware and advised me to contact Ford Motor Company and not to drive my car until something can be done. I have contacted Ford Motor Company, and they have yet to do anything or reach back out to me regarding this safety issue. The car is available for inspection at any time needed since it is still sitting at the dealership with the second rebuilt transmission in it that is no good.

My 2019 Ford Mustang Ecoboost Premium Fastback is having an issue with the transmission. When I shift from park to reverse or from reverse to drive, the car makes a clunking noise. There are times when i do a doubletake in my rear view mirror to see if someone has hit me in the back, this happens sometimes when i shift into reverse. Also, I have to stay back at least a car length behind vehicles as the car will sometimes lunges forward which can cause an accident. Will be taking my vehicle into service for this problem.

While driving at normal road speed, the vehicle suddenly displayed multiple warnings at the same time indicating that AdvanceTrac (electronic stability control), traction control, and ABS were disabled, and the vehicle entered a reduced functionality state. These warnings appeared simultaneously without any hard braking, loss of traction, or driver input at the time. The warnings and system faults then cleared in a cascading manner over a short distance, with each system returning one after another while continuing to drive, without shutting off the engine. After approximately a few thousand feet, all warning messages disappeared and the systems appeared to return to normal operation on their own. This has occurred more than once since ownership. The first occurrence happened at approximately 50 mph. The second occurrence happened at approximately 20 mph and occurred only seconds before an emergency braking event in the rain to avoid a collision. At the time the warnings appeared, the vehicle had temporarily lost ABS, stability control, traction control, and related braking assistance systems, creating a serious safety risk during an actual emergency maneuver. After the events, an OBD-II scan was performed and no stored fault codes or diagnostic trouble codes were present. However, for the next several engine on/off cycles, the steering and traction control behavior felt abnormal, as if the systems were only partially engaged, even though no warning lights or messages were displayed. No permanent warning lights remained illuminated afterward. The problem is intermittent and difficult to reproduce. No collision occurred, no repairs have yet been performed, and the cause is currently unknown

Backup camara is not working

I am filing this complaint regarding a vehicle I purchased from Florida Fine Cars in Miami Gardens on [XXX}. The vehicle is a Ford Mustang GT with a Roush supercharger (VIN: [XXX] ). Immediately after purchase, the car exhibited serious performance and safety issues that were never disclosed by the dealer. Within hours of driving home, the vehicle showed severe power loss, hesitation during acceleration, and loud mechanical noises at highway speeds. These issues were not detectable during the brief, low-speed test drive the dealership provided. Additionally, by the next morning, the car emitted a strong plastic or chemical odor under the hood, which intensified in the Florida heat — suggesting a possible engine, exhaust, or emissions-related fault. The dealer misrepresented the condition of the vehicle, repeatedly claiming it was “fully inspected” and “in excellent condition.” However, a certified Ford dealership technician later confirmed that the car “ran like garbage” and required immediate diagnostic attention. These defects are potentially safety-related, as they directly affect the engine’s performance, drivability, and emissions integrity. The vehicle could stall, lose power during acceleration, or emit toxic fumes. Florida Fine Cars has refused to take responsibility, despite clear evidence that the car was sold with undisclosed defects. Their actions constitute false advertising, misrepresentation, and a disregard for consumer safety. I urge NHTSA to record this complaint and investigate whether similar vehicles sold by Florida Fine Cars (or others with aftermarket superchargers) have unreported safety or emissions defects. This poses a serious risk to consumer safety and compliance with federal motor vehicle safety standards. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My door pops open while driving. You can hear it and the dash lights up that the door is ajar. Have to pull over and open and close the door. This has happened multiple times during various speeds and road conditions. Ford has recalled the door latches on the years prior but this year is not included. It has been occurring for over a year about 3 times a month.

The contact owns a 2019 Ford Mustang. The contact stated that while driving at various speeds, the front driver's side door suddenly unlocked and became slightly ajar. The contact immediately opened and closed the door, and then securely locked the door. The contact became aware of information related to the locking mechanism; however, the contact was unable to locate the information. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not informed of the issue. The failure mileage was approximately 82,000.

The contact owns a 2019 Ford Mustang. The contact stated that the passenger’s and driver’s side door latches unlocked while driving approximately 70 - 75 MPH, and the doors became slightly opened. The contact grabbed the interior handle and closed the door. The contact had received information related to the door lock failures. The vehicle was taken to the dealer, and the contact was informed that the vehicle could not be repaired under recall because an undisclosed campaign had expired in November 2025. The vehicle was not repaired. The manufacturer was informed of the failure by the dealer and confirmed that the recall campaign had expired. The failure mileage was approximately 144,000.

All the lug nuts on my vehicle needed to be replaced due to swelling of the lug nut. The lug nuts were almost impossible to remove. If I would have had a flat tire the tire could not have been removed from the side of the road which is a safety hazard. I had the lug nuts replaced at Friendly Ford in Las Vegas, NV. I was told by the dealership this is a normal problem with the lug nuts Ford is using now. I live in the desert so I am confused how moisture can cause lug nuts to swell when there is very little humidity. This is a known problem for many Ford vehicles why are they allowed to put defective parts on vehicles?

The contact owns a 2019 Ford Mustang. The contact stated upon servicing the vehicle, the dealer informed her that the outer shell of the lug nuts was swollen, hindering the replacement of tires. The dealer replaced all 16 lug nuts. The vehicle was repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline. The failure mileage was approximately 54,136.

As I was driving on the highway I slowed down due to traffic and I noticed a drastic change in the brake system responsiveness Applying regular pressure to the brakes did not stop the car. A brake system warning message appeared and I had to apply both feet to the brakes to stop the vehicle.

My name is Michelle Wright and I have purchased Ford vehicles most of my life. I love Ford vehicles and have had amazing experiences with Westlie Ford and Landmark Ford. I purchased my vehicle at Vancouver Ford, which is the most unprofessional and unethical dealership. My story starts October 2021, when I purchased a 2019 Ford Mustang from Vancouver Ford. I paid cash for the vehicle and was provided an AutoCheck, not a Carfax the day I had purchased this car. Over the last 8 months I have had several issues that made think my car was an accident but was assured it was never in an accident. After pulling the Carfax, I realized it was in a wreck and had an accident date of July 2019. This led me to look for an accident report, which was filed by a Portland Police officer on July 23, 2019.
