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.

Began over last month with difficulty or rough engine start in mornings Then engine overheated once and continues to lose coolant without visible sign of any leakage. Scan error codes P0300, P 0303, P 0304. Now with excessive steam/smoke out tail pipe when it-??s started. Took to mechanic where they verified engine coolant is in atleast, cylinder #3. My safety and that of others is the engine can fail or completely break or explode while driving, causing failure to be able to control vehicle, possibly resulting in a crash or even death.

While driving at approximately 40 MPH, my vehicle briefly sputtered, and the check engine light was on. The vehicle seemed to return to normal functionality afterward, but upon inspection at a FORD dealership, I was informed that coolant intrusion had caused damage to the engine. As a result, I was advised that the engine needs to be replaced. There are many others that have complained about this problem and to solution. My car has 81.5k miles on it.

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.

I had a solid check engine light 2 days ago and called my local Ford dealership and made an appointment for the next morning. I had not experienced any problems that I really noticed with the performance of the car, maybe some rough shifting. I waited at the dealership while the assessment was done and they said they would have to keep it overnight to do a head gasket test. They called this morning and said that I could come get the car if i needed it but I would need to keep a check on the coolant. I decided to leave the car at the dealership. After the call, I researched the web for similar issues that this particular mustang might have and I started to worry after the info I found and the similar comments on the 2019 mustang owners on this website.

Bought the car for my son August 2. The engine light came on the end of October, the Ford dealer was backed up once they took a look at it in the beginning of November. They told me I needed a whole new engine due to a coolant intrusion problem. Where I bought the car from state it came with a 12 month/12,000 mile warranty but warranty company is not covering that issue. This should be a recall and the engine should be completely covered.

I drive a manual 6 speed mustang gt 2019 the hazard that this vehicle is presenting and have seen many others complain about with a similar isssue that can be lethal causing an accident injury or even death. The mustang is known to have a reverse lockout feature with a collar and a plastic assembly where the shifter is, but it seems as it was poorly designed or poorly assembled as the problem many mustang owners are having ;such as me is that the vehicle will go in to reverse gear without lifting up the collar or in other words without disengaging the reverse lockout so instead of going into first gear it will go into reverse same goes for the second gear. I put the clutch in and put it in first or second gear or even just slightly pushing the shifter towards me and the reverse camera will turn on that is very unsafe and dangerous I recall this being also a dangerous thing for the Shelby gt350 recall number 19B34 it-??s not only a issues on those vehicles but also on the mustang 2019 Gt and other years

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.

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.

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.
