My 330i 2018 bmw has a cracked in the oil housing unit. This is due to bmw putting plastic parts instead of aluminum. After researching this I found thousand of people complaining about the sane thing. The car overheats and sometimes the oil gets mixed into the coolsnt system b causes more damage. This seems to happen on cars with mileage between 60-70 on engines B46, B48 n B58z

Car coolant is leaking due to a bad plastic coolant vent line. I had this issue in January 2023 where it was covered under a recall. I tried contacting the bmw dealership who fixed this recall and they stated there was no current recall. Although is the same issue again.

Multiple codes came on right after I had gotten my thermostat and my water pump fixed. However it ended up being that there was more leaks throughout the rest of the car. The car has currently cost me $3400 to fix and it’s still not fixed because nobody can figure out where the actual leak is coming from. The coolant is leaking and nobody can figure out where, it’s been having jerking issues since it started leaking and I read on other Bmw’s that the coolant leaks into the head gasket, causing the engine to blow

Cylinder Head Hose Expansion Tank Replacement - Coolant leaks out completely - This repair has been done twice on this vehicle with only 26K miles. BMW USA states no recall but the dealership informed me they have issued a bulletin but just put back on the defective hose since no other replacement hose is available...I'm paying out of pocket for the repair.
