2019 Ford Mustang

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 contact owns a 2019 Ford Mustang. The contact stated that while shifting from reverse(R) to drive(D) or from park(P) to drive(D), the vehicle jerked before shifting into the intended drive mode. While driving at approximately 50 MPH, the vehicle was shaking abnormally while accelerating. The check engine warning light had illuminated intermittently. The wrench symbol was displayed on the instrument panel, and the vehicle lost power. They waited for a while before restarting the vehicle. The failure was intermittent. The vehicle was taken to the dealer, who diagnosed that there was a failure with the transmission, but had not determined which part in the transmission had failed. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was unknown.

Took car into dealership because it was running rough at start up and check engine light came on. They told us today that coolant leaked into cylinder requiring head gasket repair and pissible engine replacement. The car has less than 40,000 miles, has been gently driven, with full service records from the dealership and the extended warranty just ended in July 2024. Reading online forums, this is a very common issue due to design flaw of the Ford Ecoboost engine. What recourse do we have?

My 2019 Ford Mustang Shelby GT350 was driving fine until all of a sudden I got a check engine light on the dash. The vehicle was not as responsive as usual and was shaking a little bit at idle. I shut the car off and then had it towed to the Ford dealership for further analysis. After inspection at a dealership it was identified, that my engine had failed. Cylinder 8 would not hold compression and had cracked the engine block. This failure can cause complete engine failure and can be a risk to the driver, passengers and anyone else in traffic.
