Engine Failure. In the right situation, complete loss of power of vehicle could cause several safety problems including Injury and/or Death. The problem was determined by the dealer and Extended Warranty Inspector. There were no warning lamps or any other indications of a complete engine failure. No smoke exiting the exhaust, no contaminated oil, plenty of coolant in radiator, and was not making any noise. Reason for taking the car in for service was, on Oct 1, 2024 the gauge was acting erratic. The car never ran hot. The car was taken to the dealership on Oct 2, 2024. 2 days after, received a call with results stating that I need a complete engine replacement due to overheating and coolant found in cylinder #3.

Ford currently has a TSB (15-0192 idle smoking) out on the Ford Mustang, specifically my car. They know it is an issue, and that several people are having problems with it. But they are not considering it a recall. These cars are having heavy amounts of smoke residuals, which is both damaging to the environment, and to people-??s respiratory care as it is blowing major amounts of smoke in the air, and therefore cannot pass an emissions test in my state of Virginia specifically. I believe that Ford knows this is an issue and it should be considered a recall based on current Efficiency and energy standards for vehicles.

The 2016 used car that I bought in 2017 with 20,711 miles has a defective ecoboost engine that leaks coolant on to the cylinder heads & causes engine failure. The vehicle has less than 100,000 miles & is currently in engine failure. Ford knew about this defective engine & never sent me a recall. There are class action lawsuits in CA & DE against FORD for the same ECOBOOST engine in my car. They want to charge me $12,000 for a new engine. I had a 5 year 100,000 mile warranty expire due to 5 yrs expiration & not the mileage, during covid while the car sat in front of the house & was barely driven. Once covid lifted restrictions I drove to Florida & put some miles on it locally & the engine is failing. This is absolutely absurd & Ford should be held accountable & be investigated in the state of MD for consumer fraud. This defective ecoboost engine dates back to 2012. They never should have sold me a car with a defective engine

A warning light appeared warning that the engine was overheating. However the temperature hand never indicated this. I pulled over immediately and turned the car off. I had it towed to a dealership that would accept my extended warranty. They discovered that the engine block was cracked and that the vehicle will need the engine replaced. My warranty company will not cover it because they said it is a known defect from ford. I know that ford had this same issue on other ecoboost engines but mine is a 2.3l and they have not included that one in the recall.

The bolts holding on the valve covers were not torqued correctly and were finger loose when I found them. I was lead to this discovery because there was a constant burning smell which turned out to be oil leaking out and falling on the exhaust. I found out on a forum that this seems to be a very common problem with 15-17 Mustangs. Additionally, there is a Technical Service Bulletin out explaining to mechanics that Ford did not add enough bolts to hold the valve covers on, leaving 4 or 5 blanks on both sides. Also, the newer 5.0 engines have all the necessary bolts, so basically, Ford thought they could save money by skipping 8-10 bolts on each car. I've already spoken to a Ford dealership and they said they'll have to charge me (unsure of how much yet) to repair a car they didn't build right in the first place! Please look into this.

I purchased the vehicle new and have driven it 21085 miles. Since I've owned it, I have had to add 23 quarts of additional oil to keep it full (1qt. every 500-1000 miles). After a couple complaints to Ford, they have advised me that this amount of oil consumption in this vehicle is normal. My warranty expires in March and I'm concerned about the cost of repair after the warranty is up. From a safety standpoint, I'm concerned if the engine were to run out of oil in a traffic situation. I am 74 years old and use the car for weekend, summer pleasure. I don't race it and don't allow others to drive it. Please let me know if other similar vehicles have this issue and if anything can be done. Thank you.

My car is a single owner car, that has documentation of regular oil changes, engine upkeep, and general maintenance since its purchase in 2016. No major issues had been experienced until August, 2023. While driving the car home from work, I felt an immediate loss of power from the engine, my a/c went out, and an error flashed saying the temperature sensor for the cylinder heads showed the engine was overheating. So, in 100+ ?F weather, I pulled the car over and turned it off. I let it sit for just over 15 minutes before turning it back on, only to find the car was still in failsafe mode. With less than five miles to return home, I drove, a car that refused to get up to 25 mph in the blazing heat (and no a/c), back home. I immediately called my local Ford dealership and set up an appointment to bring it in the next week, their soonest available appointment. In the meantime, I had to find people to carpool to work with. The next Monday, the car is brought in, and that day I-??m informed the cylinder head cracked and I-??d need a new engine. I couldn-??t believe it. I-??d always taken care of my car, never put it under any type of undue stress, how could the cylinder head have cracked" The dealership explained the damage was due to a well-known defect in the design of the engine. I was still flabbergasted. The engine fails, not through fault of the user, but from bad design on the part of the manufacturer, and I-??m still the one responsible to pay $8,000 for a new engine" I am disappointed Ford put out a car with engines that WILL eventually fail, and then chooses to force their customers to be financially responsible for their error. My engine losing power with absolutely no notice could have resulted in a life threatening car accident had I chosen to drive the freeway that day, or could have forced me into unsafe situations had I been traveling. I will never buy a Ford again based on this experience and the business practices displayed.

2016 Ford Mustang V6 This is EXTREMELY concerning as it's a SAFETY issue losing power features while the vehicle is in motion. While driving the car provides an error message with a wrench sign/icon stating the transmission is not in Park, then it proceeds to shut down the car leaving us without power steering. The car need stopped, move the transmission to Park, and start the engine. Doing this clears the warning and you are able to drive the car without any problem. The two incidents occurrences were about 1 or 2 months apart.
