The overheat light came on in the car a 2017 Mustang Ecoboost with only 82,000 miles. Had the car towed to the Greenway Ford dealership in Orlando and they said that there was evidence of coolant in one of the cylinders and the engine needed to be replaced. The Service Advisor at the dealership said that this was a known issue with the 2.3 liter Ecoboost engine and premature engine failures. An engine overheat could be a safety hazard or create an issue if the engine failed in traffic or on the highway.

To provide some context, I purchased my Mustang new in 2018, and it currently has 40,000 miles on it. Approximately four weeks ago, I began experiencing a "shaking" issue when cold-starting the engine, accompanied by the check-engine light turning on. I brought my vehicle into your service department, where I was informed by the service representative that the problem was related to the spark plugs. After paying $600 for what was purported to be a fix, I retrieved my car, which drove fine for about a week before the same issue recurred. The engine began shaking again, and the check-engine light reappeared. I promptly scheduled another appointment, explicitly mentioning that the problem was identical to the previous one. Upon dropping off my car, I was told that the mechanic couldn't determine the issue from the initial diagnostic. After three days without any updates, I reached out to my service representative, Jack, who then informed me that my car required an engine replacement due to a coolant leak—a problem he described as a common issue with EcoBoost engines. The cost quoted for this repair was $9,000, an amount I find exorbitant given that my car's total value is around $12,000-$13,000. My primary concern now is the nature of the engine issue. Given that this problem is apparently common with EcoBoost engines, I believe it is a manufacturing defect that should not be my financial responsibility to fix. Furthermore, during my research, I discovered recalls and class action lawsuits related to this exact issue—information that was never communicated to me by your team or at the time of purchase. Unfortunately, my vehicle is not included in these recalls. Coolant leaking into the engine will eventually make my engine overheat and potentially crack the engine. This is a manufacturing issue, and should not be my financial responsibility.

The contact owns a 2017 Ford Mustang. The contact stated that while driving at approximately 15 MPH and making a U-turn, the engine overheated, and the vehicle stalled. There was smoke coming from the tail pipe. There was an abnormal odor of coolant in the vehicle. The contact opened the hood and noticed that the engine oil was milky, and the coolant reservoir was empty. The engine overheated, and the message ā€œLimited Power Due to Overheatingā€ was displayed. The check engine warning light was illuminated. The contact researched the failure and indicated that the failure was due to the head gasket and engine. The vehicle was towed to the local dealer but was not diagnosed or repaired. The manufacturer was contacted and opened a case. The contact was referred to the dealer for assistance. The failure mileage was approximately 83,000.

I was driving and the vehicle jerked, the check engine came on and I immediately pulled over. The car was towed to a local mechanic who said take it to ford because this is a known issue with 6 cylinder engines. Today, ford called and said it’s a catastrophic engine failure and nothing I did. The cost to replace the engine is $10,000. My car had 97,000 miles and was always well cared for. If ford knows this is an issue, it should be a recall.

Car leaking Freon for years causing black mold throughout the car and directly in my face for years. It’s otorless but does smell musky like black mold the technician said. Repair shop stated Freon leak but can’t locate it resulting in me losing my job from being too sick to work from black mold overgrowth in my body from this car. My son and I have brain fog, digestion issues, clumsy, sinus and throat always has mucus, fatigue and overall feeling of being unwell. This has caused my now 4 year old son and I to be in and out of the hospital for about 2 years but the last year was really bad. Ford is not acknowledging this is a problem however I found a TSB listed online. Please help me get this car fixed or help me get out of this car as it is killing us resulting in poor quality of life and life long health issues that affect our lives every day.
