2019 Ford Mustang Engine

Noticed vehicle was running rough on idle intermittently when sitting at a stop. I thought this was due to it being a very cold winter where I am located, but after a couple months, check engine light came on and was immediately brought in for service. Coolant was found leaking into a cylinder and I had to have head gasket as well as upper portion of engine replaced. From the research I have done there have been a lot of people with the same issue as mine and a design flaw in spacing between cylinders. Incident occurred less than 10,000 miles out of warranty and was not covered.

The contact owns a 2019 Ford Mustang. The contact stated while driving 40 MPH, the vehicle briefly sputtered before returning to normal functionality. The check engine warning light was illuminated. The vehicle was taken to the dealer, who determined that the coolant intrusion had damaged the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. After investigating the failure, the contact related the failure to Customer Satisfaction Program: 21N12. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was 88,000.

My 2019 Mustang EcoBoost 2.3L i4 has experienced the coolant leak described in the on going lawsuit. I have serviced the vehicle on time Everytime and I still had to pay $10K to have the motor replaced. Why has the Mustangs not been mentioned in the lawsuit nor recalled for this?

The contact owns a 2019 Ford Mustang. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated on the instrument panel. The vehicle was taken to an independent mechanic, who determined that there was a misfire in cylinders #1 and #3, requiring the replacement of the spark plugs and ignition coil. The vehicle was repaired, but the failure reoccurred. The vehicle was then taken to the dealer, who determined that coolant intrusion had damaged the engine, requiring the engine to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 71,000.

Check engine light kept coming on for a misfire after my car was shaking in idle for months. By the time check engine light came on, the code read misfire cylinder 2. Assumed at first it was spark plugs or ignition coil, so I replaced those and still was having the issue. Check engine light was still coming on and misfire was still happening. Took car to auto shop and was told I need a new engine due to coolant leaking from engine into cylinders. Took car then to Ford dealership for them to review the problem and they came up with same conclusion and even said that this is a common problem with the Ecoboost engines. This is a KNOWN problem by Ford, and they have since corrected the issue with a new and improved engine, however they expect customers to pay for their defective engine replacement. My car is at 62,000 miles. It should not need a new engine. They sold me the car new, when Ford was well aware of this common issue which can become extremely dangerous.

Cylinder number 2 on the Engine block is leaking antifreeze.

I was driving on the the 215 Freeway in Las Vegas and the car started to shutter with a loss of power in the engine. The check engine light starting blinking orange. I was going downhill so I let the car coast while I tried to pull off the road. After about 15 seconds the engine stabilized and the check engine light stopped blinking and stayed a solid yellow. I pulled the car off the road and let it rest. I was able to get the car home and took it to V & V Auto in Las Vegas the first appointment I could make. I was told coolant was leaking into the engine and the head gasket needed to be replaced. The mechanic told me this is a design flaw with the Ford EcoBoost Turbo Engines. Why is Ford allowed to put faulty engines on the road? I only had 64000 miles on the car at the the time and I have always had the car serviced.

The contact owns a 2019 Ford Mustang. The contact stated that after starting the vehicle, the check engine warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the spark plugs, and ignition coils needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was towed back to the independent mechanic, where it was diagnosed that the spark plugs, and ignition coils needed to be replaced again. The vehicle was repaired; however, the failure recurred, and the independent mechanic advised having the vehicle diagnosed by a local dealer. The vehicle was then towed to a local dealer, where it was diagnosed that the engine needed to be replaced. The vehicle remained at the dealer awaiting the repair. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The approximate failure mileage was 106,000.

I have taken my vehicle to Ford. Called Ford as well. And when at a stop, and while in drive, my car will lunge/ jerk and if my car was behind a vehicle too close could hit it. I also believe that If a person were in front of the vehicle it could lunge forward into them. I see in google that many 2019 mustang owners have reports this as well. This jerk/ lunge has happened a hand full of times. Two Ford dealerships and ford.com have advised they do not have reports from consumers on this.

Car was taken to FORD for diagnosis because it was running oddly and the service light kept coming on. After taking it in Ford said there was nothing wrong with it and 2 days later it blows a head gasket and comes to a screeching halrt and the motor seizes.

TL* THE CONTACT OWNS A 2019 FORD MUSTANG. THE CONTACT STATED WHILE DRIVING AT 15 MPH, THE CONTACT HEARD A KNOCKING SOUND IN THE ENGINE. THE CONTACT STATED THAT THE CHECK ENGINE WARNING LIGHT WAS ILLUMINATED. THE CONTACT WAS CONCERNED ABOUT DRIVING THE VEHICLE AND HAD THE VEHICLE TOWED TO BILL CURRIE FORD (5815 N DALE MABRY HWY, TAMPA, FL 33614) WHERE IT WAS DIAGNOSED WITH THE ENGINE NEEDING TO BE REPLACED. PRIOR TO THE CONTACT OWNING THE VEHICLE, THE PREVIOUS OWNER HAD THE ORIGINAL ENGINE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER HAD BEEN INFORMED OF THE FAILURE AND INFORMED THE CONTACT THAT THE VEHICLE WAS NOT UNDER WARRANTY. THE FAILURE MILEAGE WAS APPROXIMATELY 28,000.

WHILE DRIVING MY GT350 ON A HIGHWAY AT AROUND 55 MPH THE ENGINE MADE METALLIC GRINDING NOISES SUDDENLY, AND WITHOUT WARNING. I INSTINCTIVELY PRESSED IN THE CLUTCH PEDAL AND THEN ENGINE STOPPED SPINNING AND LOCKED UP. I WAS FORTUNATE TO BE IN AN AREA WITH A PULL-OFF AREA AND THIN TRAFFIC. IT COULD HAVE BEEN VERY DANGEROUS AT HIGHER SPEEDS, IN THICKER TRAFFIC, OR WITH A LESS EXPERIENCED DRIVER. ONCE STOPPED, I CHECKED THE CAR AND CONFIRMED THAT THE STARTER COULD NOT SPIN THE MOTOR DUE TO MECHANICAL FAILURE. THERE WERE ONLY ABOUT 450 MILES ON THE VEHICLE WHEN THIS HAPPENED. I WAS LATER TOLD BY THE DEALER THAT THE ENGINE HAD AN ISSUE WITH A ROCKER AND VALVE, WHICH CAUSED THE ENGINE FAIL AND LOCK UP. A REPLACEMENT ENGINE ALSO HAD 'VALVETRAIN NOISE' AND WAS DETERMINED TO BE NO GOOD BY THE DEALER. I DID NOT SEE OR USE THE CAR WITH THAT ENGINE. BEYOND THAT, THIS ISSUE IS STILL UNRESOLVED AS THE CAR HAS NOT BEEN REPAIRED.
