2021: “The car basically blew up on the highway at rush hour. BMW knows of this issue with this model and has some of their other models under a recall for this very thing. I have a service action from BMW saying that the water pump assembly needs to be fixed before this very problem occurs but for some reason even though our model is on the service report it isn't on the recall list nor was this part replaced as instructed even though the vehicle has always been service at a BMW dealership. …”
