2016 MINI Clubman Engine Problems

I have 2016 Mini Clubman S with 109,000 miles on it , I got a check engine light with a Code U019D. I went to dealer to check and was told the radiator would need to be replaced at a cost of $ 3,700 dollars. After researching it is a common issue due to defect in materials, there was an extended warranty offered by bmw up 15 years or 150,000 miles to cover this defect. I was told that since I am in Florida it doesn't cover it and I believe this is wrong. If there is defect in materials and it is covered for some, why not all. Th ecompany has already stated it is a defect in materials, see below. SIM 13 01 19 Lin Bus Communication Fault for Enviromental Air Catalyst (EAC)Sensor FC1B8302. It States that the chemical compositon of the fan shroud contaminates the EAC sensor. Since this is a know defect from manufacturer I believe they should be replacing the defective material under warranty terms .

I am writing to formally express my concerns regarding a 2016 Mini Cooper Clubman S that I purchased in August of the previous year, with 64,000 miles on the odometer. Within just two months of ownership, the vehicle began to exhibit serious mechanical failures. Initially, the water pump failed and had to be replaced. Shortly thereafter, the air conditioning system on the left side malfunctioned. Most alarmingly, the engine suddenly stopped and began to overheat while on the road, necessitating an emergency stop at a nearby mechanic's workshop. The diagnosis revealed a catastrophic engine block failure, with a crack that caused the antifreeze, oil, and possibly fuel to mix—an issue that could potentially lead to a vehicle fire. This vehicle is primarily driven by my wife, who frequently transports our [XXX] son, who is [XXX]. The potential risks had this occurred on a highway are unimaginable and could have led to fatal consequences. Upon discovering these issues, I immediately contacted Mini to inform them of the defect and requested a comprehensive diagnostic examination. I emphasized the possibility that this could be a production line issue, which might affect other vehicles and thereby pose a significant risk to other families. Regrettably, the response I received was dismissive; I was informed that nothing could be done, and my request for a vehicle inspection was outright denied. Given the severity of these issues and the potential risk to human life, I urge your immediate intervention. It is imperative that this matter be revisited and that a thorough investigation into this potential production defect be conducted. Ensuring the safety of all consumers must be a priority, and I respectfully request that my vehicle be inspected at the earliest to prevent any potential future tragedies. Please advise on how we might proceed in this matter. I look forward to your prompt response. Yours sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
