2019 FORD MUSTANG Complaints

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

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. Vehicle VIN is the following: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Ford's 2.3L EcoBoost engine defect that causes coolant to leak into the cylinders, leading to engine failures and potential fire risks.

Blown Head Gasket @ 86,000 miles due to Block defect. Now I have to either pay to replace the Head Gasket with the expectation that it will fail again due to the block defect, or replace the whole defective block.

When placing the car in reverse the backup works sometimes and most times it does not. Similar to other Ford vehicles currently under recall. I am of the belief this recall should be expanded to include additional years and models.

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

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)

Engine - Blown head gasket This is a common issue with these engines and is a costly repair or potential engine failure.

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.
