Our vehicle alerted us to over heating and to pull over immediately. Our car then stopped running. We had it towed and was told there was an issue with the water pump sensor and corrosion issues. They alerted us that there was a recall for these issues on our vehicle. We researched and found this to be true. When I contacted BMW they stated our vin number was not part of the recall but our vehicle match the exact models listed in the recall. We took it to the dealership and they repaired it for $2500 and the reason for the repair was the exact reason for the recall. Spoke with BMW again regarding this and they said if our vin was not on the recall list there was nothing they could do. I would think when your vehicle make and model matches the recall and the issues are the same you would be part of the recall no matter the vin number. …
