NHTSA Complaint #11692532 — 2018 BMW X3

Vehicle: 2018 BMW X3 VIN: [XXX] My 2018 BMW X3 has had continuous oil and coolant leaks for several years. Major parts have already been replaced including the turbocharger, oil cooler, water pump, turbo lines, radiator hose, thermostat, and valve cover gaskets. The dealer recently confirmed my crankshaft seals are leaking. These issues are consistent with a defective Positive Crankcase Ventilation (PCV) system, which causes excess crankcase pressure and oil leaks. BMW issued an Extended Limited Warranty for PCV/valve cover defects on other models but said my VIN isn’t included—even though I’m experiencing the same failure pattern. This creates potential fire and safety hazards from oil leaking onto hot engine components, as well as the risk of sudden engine failure and environmental hazards from oil dripping onto roads. I respectfully request that NHTSA investigate whether 2018 BMW X3 vehicles should be included in BMW’s PCV/valve cover recall or extended warranty coverage.
