What component or system failed or malfunctioned, and is it available for inspection upon request? The flexible brake hose on my 2015 Ford Edge failed/broke shortly after I purchased the vehicle. The vehicle also began experiencing engine performance issues, including a rough idle and rough driving condition after the check engine light came on. The vehicle and failed brake hose should be available for inspection upon request. How was your safety or the safety of others put at risk? The broken flexible brake hose created a serious safety risk because it could affect the vehicle’s braking ability and increase the risk of losing control or being unable to stop safely. The rough engine performance also caused concerns about the reliability and safe operation of the vehicle while driving. Has the problem been reproduced or confirmed by a dealer or independent service center? The issue has been observed and experienced consistently while driving the vehicle. The brake hose damage and rough engine performance were noticeable after the vehicle was purchased. (If a mechanic has looked at it, you can add: “An independent mechanic/dealership confirmed the brake hose was damaged.”) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? I have taken it to the dealership and they said nothing about it but I got it diagnosed at autozone and the code came up right away. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Approximately 2–3 weeks after purchasing the vehicle, the check engine light came on and the vehicle began running roughly. Around the same time, issues related to the broken flexible brake hose were discovered. Symptoms included rough driving performance and concerns with the braking system

Had a misfire when starting the vehicle so took it to a mechanic. There is a coolant leak in the engine block which appears to be a major problem with this year and make. Can cause engine failure and other problems.

Coolant is leaking into cylinders. This is causing a misfire. Ford calls for a long block replacement due to the original long block not being thick enough.

My Vehicles Engine had a Cylinder #2 Misfire that was a result of Coolant Intrusion. This issue seems to be a known issue and Ford did correct for post 2019 vehicles, but I had to pay over $8,000 in repairs to get a new motor because that Coolant Intrusion issue ruins motors. I don't understand why I am responsible for this egregious problem Ford never corrected for 2015-2019 Ford Edge Owners. In no way should a person be responsible for over $8,000.00 in repairs on a vehicle that failed from a Manufacturing defect/error/issue. This expense is now a financial burden on not only myself but my family. I had to take a personal loan out to cover the cost. Certainly unfair. I have owned this car since it was brand new. only owner and it's been wonderful until this issue has appeared. i'm begging the federal safety agency to force Ford to reimburse owners of these repairs. I did not do anything by driving my vehicle to cause this issue when there is a identified flaw. Thank you
