I own a 2020 BMW 330i xDrive with an open safety recall involving a fire risk related to the engine starter. The recall has been open for approximately five months, and BMW has not provided a remedy or repair timeline. I have been informed that parts are unavailable, and no interim fix has been offered. This defect presents a serious fire hazard, and I do not feel safe operating the vehicle. I am currently pregnant, which increases my concern for personal safety and the safety of my unborn child. Despite the unresolved safety recall, I am still required to make monthly payments on the vehicle. BMW has not provided alternative transportation or sufficient guidance on how to safely manage this situation.

The Oil filter housing on my BMW 330i failed randomly while driving causing my vehicle to be depleted off coolant within seconds. If you want to inspect the part you will have to reach out to bmw of Columbus for documentation and I can provide the service records for repair. This caused my vehicle to have to be brought to an immediate halt to not cause overheating or engine destroying failure at a time where service/repair isn’t available. There were no warning lights or leaks prior to the vehicle malfunctioning all at once. I ubered to get coolant and once filling the reservoir the coolant immediately leaked out resulting in me needing a tow to the dealership. This problem has been reproduced with many dealers as there’s numerous of report of this online and I believe the dealer has inspected this part but is refusing to replace or recall this part under any type of program or create any type of solution to make this not happen again. There wasn’t any small leaks or warning lights shown before this issue spawned all at once then showing the low coolant light.

Both the UPPER and LOWER active grille shutters for most BMW models in the 5 model years prior to mine had extended service warranties due to frequent failures of the part. It appears that the design was not improved with my model year and yet my vehicle is NOT part of the extended warranty. My vehicle is only 4 years old and BOTH the upper and lower air flap control motors have failed. The motors are not sold individually, but are sold as a part of the entire shutter assembly which has a part cost of $250 - $350 each with comparable installation costs. The lower shutter assembly requires the removal of the entire bumper. Why is the extended service warranty not applicable to newer models?
