For three years, this Mustang will lurch frequently after you shift into first or reverse from park. I had it looked at Paradise Ford 3 years ago and they REFUSED to look at transmission until the car had 125k miles on it. At that time, the car only had 98k miles on it. I tried to insist, but they refused. The service helper was named Mark, I believe. The other day I was driving on a 10mph park road .....more like coasting because it was a low speed limit. The car suddenly jerked forward. Today I took it into Gary Yeoman Ford in Palm Bay, FL for a transmission check. The service advisor was Jason. They said there was a cdf hub issue and stated I needed a new transmission for 6600.00. Of course I refused and came home to research their "diagnosis". I found an article about a,10R80 bushing that has caused the same exact problem is other Mustangs. I feel like they were giving me the run around. I don't want this to cause further problems. It should have been fixed at Paradise Ford. I have owned this car for 5.5 years. I'm quite familiar with how it runs. Please advise.

The radio screen which controls the back up camera climate control, and everything else has gone black and only turns on once every few weeks, when car is turned off it does not come back on. After a diagnostic test done at Yark Ford they recommended a APIM module and this would run $1412.70 + tax. After throughly investing this on the internet this is a common problem with this year and model. Ford should offer a recall!!

Due to a faulty design were antifreeze is allowed to get into the cylinders and mix with the oil, the engine malfunctioned while I was on a busy highway and I barely got off the road onto the shoulder. It was very dangerous. I thought it was an isolated incident but it happened again. Now they want to charge me $8,400 to replace a defective engine. I know some of Ford's similar engines are being recalled. Thank you

On multiple occasions now, the passenger side door has randomly opened, which sets off the door ajar warning, and I have to pull over and close the door. In addition, again randomly, the passenger side door locks will unlock, then relock, usually several times in rapid succession. Both situations seem to occur only when the vehicle is in drive, and not while in park. The vehicle is available for inspection; Fortunately, no one was sitting in the passenger seat when these instances occured; The problem has not yet been diagnosed by a dealer or service center; It has not been inspected by anyone; There were no warning lamps or messages prior to the failure, only after the door popped open. I am making this report prior to having it inspected by the dealership because it seems to be a very common problem with other Mustang owners as evidenced by this site, as well as on Mustang forums.

We purchased this vehicle for my daughter as a graduation present and while she was driving it the engine malfunctioned stranding her on a busy highway. We then found out it is the defective EcoBoost engine manufactured by Ford that was the cause of this incident.

Ford Incorporation is selling vehicles with malfunctioning engines. Ford cut in between each cylinder block to allow the coolant to cool the engine, however this design is extremely flawed, it causes the head gasket seal to break.

Ford has known about this issue for years and are not trying to put a recall on the engine. They’re making customers pay out of pocket to fix the engine. Replacing the head gasket isn’t an enough to fix the problem because the oil and coolant are mixing inside of the engine.

Just like the other Ford Ecoboost engines, mine is also leaking coolant into the engine, which is causing me to have to buy an entire new engine. The code is reading a misfire into the third cylinder initially which I “fixed” with a tuneup. Turns out, I’ll need an entire new engine.

Ecoboost Turbo engine has a known flaw - coolant channels were placed between cylinders that don't allow them to seal properly and this leaks coolant into the engine eventually causing engine failure. FORD corrected this defect in 2020 but did not correct previous customers. As a result I am now being referred by my local dealer to replace the whole engine. I have only had this vehicle for 4 years and have only used 45K miles in that time frame. I have lost power while driving WITH MY CHILDREN IN THE CAR. I've already spent thousands of dollars on repairs only to find out the issue was the engine and a KNOWN issue that Ford covered up. Ford needs to be held liable for this and they should be responsible for replacing my engine. And the time and money spent attempting to fix this issue.
