Gas Recirculation Valve (egr Valve) problems of the 2016 BMW X5

I am reporting a safety issue related to the BMW recall 18v-755 affecting the egr cooler on my 2016 BMW X5 diesel. My vehicle experienced symptoms consistent with a failing egr cooler, including coolant loss and engine warning lights. Despite this recall being active for my model and VIN, BMW has denied coverage, stating either that the cooler was already replaced twice or that my vehicle is not eligible—without providing sufficient documentation or explanation. I am concerned that the recall remedy was not properly applied or that faulty replacement parts were used. I am requesting that NHTSA investigate whether BMW is properly honoring recall 18v-755 and ensuring safe, effective remedies are provided to affected customers like myself.
