I purchased this 2019 Ford Mustang Ecoboost 2.3L brand new in July 2019. It has been well maintained, regularly serviced by the authorized Ford Dealer where I purchase the car. It has never been in an accident, and has only 36,100 miles. This vehicle passed inspection last month. The check engine light came on, and then had rough cold starts. I have been informed by the service station that antifreeze is leaking into the engine, and a new engine is required (estimated cost of $11,000). After researching this matter, it appears that there is a design flaw with this vehicle, given the high number of similar occurrences with 2015-2019 Ford ecoboost vehicles. It is my understanding there is even a class action lawsuit related to this issue. Luckily, there was no accident resultant from this engine malfunction in my case, but the NHTSA should investigate this issue, given the high risk it poses to highway safety!

My vehicle experienced a blown head gasket due to a faulty engine block design at 56K miles. The car started running rough for 10 seconds upon a cold start up and was also misfiring. This is due to coolant intrusion through the gasket and it got into cylinder 3 which could have caused catastrophic engine failure or worse.There are several class-action lawsuits against Ford for the defect.Ford has not taken any steps to address this issue with the ecoboost engines on 2015-2019 models. Additionally, Ford did NOT provide relief to me and I had to pay out of pocket to fix this.

My vehicle recently had a head gasket leak due to a faulty engine block design. I noticed one day the coolant was lower than it should be but nothing concerning, over a month or so it got progressively lower & the car would also sputter/misfire on startups from time to time. This is due to coolant slipping through the gasket & getting into the cylinder & oil which can lead to catastrophic engine failure or worse. Eventually I got a check engine light & was told it was a misfire after running a diagnostic on the vehicles OBD2. I researched what the issue could be &it became more & more apparent that it was a head gasket issue. The oil was contaminated & coolant was getting very low. Apparently it’s a big issue since Ford is now facing a class action over the defect. The vehicle also has some issues with the transmission, for example ill start the car up on a cold California morning 50°F & let it warm up before driving & when I go into reverse after the car will jolt hard as if you were backing up & hitting something like a wall, even in the afternoon when you start it from a cold start & go into reverse it will do it. Not sure why but it’s concerning to say the least. The transmission also feels confused when shifting, when I’m in 4th about to push fit it will get confused & revs will drop slightly before going up again to up shift, also when downshifting due to braking the shifts can feel a bit hard, especially when needing to stopping fast. The engine & transmission are the most importantly parts of a vehicle & without them working properly is something no one should have to face.

The 10-speed automatic transmission (10R80) in my 2019 Ford Mustang GT began malfunctioning around 84,000–85,000 miles, displaying a consistent hesitation followed by a sudden jolt during acceleration between 15–30 mph. A Ford dealership confirmed the issue and diagnosed it as an internal leak in the clutch drum assembly, referred to as a “CDF drum internal leak.” The vehicle has not shown any warning lights or dashboard messages, and the symptoms developed gradually before becoming consistent. The malfunction causes the car to unexpectedly lurch forward during normal driving, which poses a safety risk to myself and others, particularly in traffic, at intersections, or when merging. This unpredictable behavior could lead to loss of control or rear-end collisions. The transmission remains installed in the vehicle and is available for inspection upon request; however, will be fixing it soon since it is my only car. To date, the vehicle has only been inspected by the dealership and not by the manufacturer, police, or insurance representatives.

A vehicle was listed for sale in June 2025 with an odometer reading of 115,152 miles. However, a CarFax report dated March 13, 2025, showed the mileage as 37,707. This is a discrepancy of over 77,000 miles in less than three months, raising serious concerns about odometer tampering or title fraud. The issue was discovered prior to vehicle delivery, and the transaction was canceled. The dealership has not provided any explanation for the mileage increase. This discrepancy may mislead future buyers and compromise the vehicle’s maintenance and safety records. The vehicle was not inspected by a mechanic before cancellation. The concern has been reported to the Better Business Bureau (BBB), California DMV, and CFPB.

Vehicle was purchased new in 2019 and in 2022 my transmission started with harsh gear changes which resulted in a reprogram/relearn of the transmission.

We purchased a Ford Mustang for our daughter 6 years ago, and have had the following ongoing dangerous and expensive widespread issue, 6 incidents to date, caused by Ford knowingly using soy based wiring (as opposed to petroleum based) for environmental reasons, that attract rats like it was cheese. The rats have been eating through essential wiring and once in the car also eating hoses and insulation, putting our daughter’s and others lives in grave danger and costing us thousands of dollars in continuous repairs, the last time rats ate through her brakes! (luckily discovered by warning lights in her car before her brakes failed) Ford is very aware of this issue and receive many complaints but do nothing, except refer me to you after I filed a complaint with them. No warranty covers this. Only my neighbors who don't have cars with soy based wiring don't have this issue, showing that this is clearly the cause. In a futile attempt to combat this, we have expensive monthly exterminator rat service, noise makers in her car, glue pads under her car, in her car (removed when driving), spray peppermint and bleach, and check the car daily. (Governor Newsom banned rat poison in Calif making it more challenging) But these expensive and time consuming measures are not full-proof as evidence of our continual costly repairs, and nothing will work until the root cause is addressed, the soy wiring. Ford needs to replace soy based wiring with petroleum based wiring, pay for all rat damage retroactively and future repairs until the soy wiring is replaced. (I have copies of all repair receipts, dating so far from Nov 2019 through April 2025) Just one of many article links in a quick google search that shows this is a widespread issue: "Rodents can’t get enough of Fords soy coated wiring and that’s a big problem!" [XXX] Please do something because Ford won't. (you ask date of incident, I have 6, I put most recent ) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
