See attached document for complaint.
The issue at hand is the oil filter housings on the B 58 and B 48 motors that BMW manufacturers. These oil filter housings are known to break after four years or 60,000 miles. can range from the engine overheating to oil leaks. The engine overheating can total the motor and the oil leaking can become a fire hazard. I was fortunate enough to be able to replace mine while BMW replaced another common failure point which is the heat management module. However, this is not as big as an issue as the oil filter, housing, because if the oil leaks, it can become again a fire hazard. There are several forum posts online about this issue I would like for NTHA please look at this thank you.
I had a coolant leak so I took car in for repair. Mechanic says I have a crack in the oil filter housing. Mechanic told me to check with BMW to see if there was a recall because the oil filter housing was made of plastic and he claimed he heard of recalls for this particular problem. I called BMW and they stated there were no recalls currently on my vehicle, but the plastic housing in BMW's are known to be prone to failure and there were recalls, but not for my vehicle. The warning message initially stated low coolant. Now it states low oil level.
The contact owned a 2019 BMW 330i. The contact stated that while driving approximately 15 MPH, smoke was seen coming from under the hood of the vehicle. After stopping and exiting the vehicle, flames were then present coming from under the hood and the fire department was called to the scene. The flames were extinguished. The vehicle was destroyed and towed away. A fire report was taken at the scene. The cause of the failure was not determined. The manufacturer and local dealer were notified of the failure. The failure mileage was 4,500.
