ENGINE
Description of the Defect: My 2019 Ford Mustang EcoBoost experienced a premature engine failure caused by internal coolant intrusion, resulting in the need for complete engine replacement. This failure is not related to routine maintenance or a head gasket issue, but rather a known internal engine design defect that allows coolant to intrude into the cylinders over time. The vehicle exhibited symptoms including coolant loss without visible external leaks, rough operation, and engine malfunction. Upon inspection by a Ford dealership, the failure was diagnosed as coolant intrusion into the engine, with the only repair option being long‑block (engine) replacement. Ford has acknowledged this failure mode in Technical Service Bulletin (TSB) 19‑2346, which documents coolant intrusion in EcoBoost engines and states that engine replacement—not head gasket repair—is the required corrective action. This bulletin confirms the issue is caused by an internal design flaw that develops over time. Why This Is a Safety Concern: This defect can lead to sudden engine misfires, loss of power, or complete engine failure while driving, which poses a serious safety risk to vehicle occupants and other road users. Engine failure at highway speeds or during normal driving conditions creates the potential for crashes, loss of vehicle control, or roadside breakdowns in unsafe conditions. The failure occurred at very low mileage (~36,000 miles), indicating a premature and abnormal engine defect, not normal wear and tear. Yes, it is available for inspection upon request. Yes, it is diagnostic and confirmed by AutoNation Ford Bellevue [XXX] Direct line: [XXX] No, prior warning and symptoms. First appeared on March 16, 2026. No recall exists despite Ford’s TSBs acknowledging the defect. Ford later redesigned the EcoBoost engine, showing awareness of the issue, yet owners are forced to pay for costly engine replacements after warranty expiration.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, EXTERIOR LIGHTING
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.

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.

SERVICE BRAKES, STEERING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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

ENGINE
Have a 2019 Ford Mustang 2DR 2.3L Ecoboost with 59,500 miles which I took to the dealership with a code P0302 and P0304 present, cylinder misfire, observed coolant level low, performed borescope in cylinder 2 and 4, found coolant intrusion, recommend long block engine replacement which would have cost me $10,728.85. Concern is that the engine can stall suddenly and may cause an accident. Ford Motor Company knows about these kind of engine issues with Ecoboost engines and have not offer any reasonable solutions.

Purchased just 2 months ago from ford dealer, after 1 week noticed shimming of engine on cold start, next incident overheat warning, filled with radiator fluid, noticed slow lowering of fluid level, next day car would not start at all. Towed to mechanic in which they report blown head gasket and all 4 cylinders damaged. After searching this site I found others had same complaint but no recalls. Evidently there is a lawsuit, how do I participate so I can get my beautiful car repaired ASAP?

Since this recall came out I have taken my car to the dealer(Port Orchard Ford, Port Orchard, Wa. 98366) and each time they say they can't do it because it has a super charger. I think it's because they would have to reinstall the super charger program. I've been told that they would be able to reprogram it because they installed it. On the recall notice it doesn't list any exceptions to not doing the recall. XXX XXX REf. Manufacturer Recall Number 22S37 NHTSA Recall Number 22V382 Dated: May 27, 2022

ENGINE, STRUCTURE:BODY, ELECTRICAL SYSTEM
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)

Coolant intrusion into cylinder 2 at 26,000 miles. Was told by mechanic this is due to thin cylinder wall design between cylinder 2 and 3. And the thin coolant channel cut between them. A new engine block manufactured after 2020 was recommended because the engine design was changed to fix this issue. My warranty expired 4 months prior so I had to fix myself.
