   The contact owns a 2019 BMW X3. While the vehicle was at an independent mechanic for maintenance, the technician discovered an active coolant leak coming from the coolant expansion tank. The mechanic stated that the leak was caused by excessive system pressure stressing the factory plastic tank. The mechanic informed the contact that if the issue was not resolved, the failure might become a major coolant leak into the engine, and the engine would need to be replaced. The…

   I bought my 2019 BMW X3 late 2025 before Christmas. The Carfax was fine and there were no open recalls on the vehicle. The vehicle had been serviced regularly at BMW facilities. Our family mechanic looked at the vehicle before I bought it and performed some basic diagnostics. The vehicle appeared fine. There were no error codes and all of the fluids were topped off. I don't know if the issues with the coolant were there before I purchased the vehicle or if they happened…

   My 2019 BMW X3 equipped with a B46 engine developed a significant coolant leak at approximately 80,000 miles. The vehicle displayed a low coolant warning, and coolant was visibly leaking underneath the vehicle. Around the same time, I began noticing excessive white exhaust/steam during cold starts and, for the first time since owning the vehicle, had to add engine oil between scheduled oil changes. The vehicle is currently undergoing inspection by an independent repair…

   I'm reporting a safety issue with BMW vehicles equipped with the B58 engine, primarily 2019-2021 models. These vehicles have an oil pump with an internal plastic component that regulates oil pressure, and this part is fracturing in the field, causing sudden loss of oil pressure. The failure typically occurs during cold starts in low temperatures. When it fails, oil pressure becomes erratic or is lost entirely, often with little to no warning before engine damage or vehicle…

    I am reporting repeated coolant system failures and overheating on my 2019 BMW X3 . I have had 4 coolant-related repairs in under 3 years, including the coolant reservoir boiling after service. Most recently, the problem recurred despite prior repairs. This is a Certified Pre-Owned vehicle with warranty history, and I believe this is a systemic engine/cooling defect that poses a risk of engine failure or fire. Other owners may be affected. A recall or investigation is…

    While driving my BMW X3, the engine suddenly failed after the check-engine light came on, which followed several days of intermittent high-temperature warnings. Coolant levels had been consistently monitored, refilled, and topped up as needed, yet the temperature fluctuations persisted. Upon further inspection, the repair shop determined that coolant had been leaking internally into the engine due to a cooling system failure, causing overheating and warping of internal…

    Despite replacing the water pump, coolant expansion tank, hoses, and other related cooling system components, and fully refilling and bleeding the coolant, the issue persisted. Even after these repairs, the engine continued to overheat and show coolant level fluctuations, indicating an underlying problem likely pressure buildup or head gasket failure that was not resolved by replacing standard cooling parts. Dealership has identified further problems and seem like a costly…
