The Oil filter housing on my BMW X4 failed randomly while parked over night causing my vehicle to be depleted off coolant. If you want to inspect the part you will have to reach out to bmw of Columbus for documentation and I can provide the record for repair once complete.This caused my vehicle to be immobilized. If my vehicle had been on the road like previously I would’ve been stranded. There were no warning lights or leaks prior to the vehicle malfunctioning. 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 after showing the low coolant light.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 BMW X4 verdict →
