NHTSA Complaint #11706580 — 2018 BMW X4

We heard a whining sound under the hood on November 1st, 2025. Prior to noticing this noise, there were no warming lamps or messages appearing. Following a short drive we smelled burning in the garage. We did not drive the vehicle the following day and intended to take it to our mechanic on Monday morning, the 3rd. Upon trying to start the car it was dead. We had to have it professionally jumped as standard jumping with our personal jumper cables would not start it. Our mechanic explained both the battery and the water pump would need to be replaced. Upon further examination, he realized that the cable or water pump harness that connects the two had been burned and discovered a recall on thousands of 2017/2018 X4 models. He called us and encouraged us to take it to BMW as he found the recall and assumed they would take care of it. Upon calling our local dealership, they looked up our VIN and said our model was not part of the recall. We proceeded with the repair as we had to have our vehicle. Once those parts were replaced, it was also discovered that the issue caused the entire DME/ECU unit to go bad. Our mechanic then ordered that directly from BMW. Once in he had it reprogrammed and we got the car back. We were without a vehicle for a month. We would ask that you please review this as it's clear, this was the exact issue that has affected thousands of other BMW X4 Models. It is a safety issue as we smelled the burning in our garage and learned later that it could have started a fire either while driving it or in our garage at home. Our VIN should be included in the recall. Upon calling BMW of North America Customer Service, they told us to file a complaint on nhtsa.
