Owner complaint summary

Subject: 2019 BMW X5 xDrive40i – Oil Pump Defect Causing Oil Measurement Failure and Safety Risk I am reporting a safety defect in my 2019 BMW X5 xDrive40i with the 3.0L B58 inline-6 engine. The vehicle currently has approximately 70,000 miles. The vehicle is unable to properly measure or display engine oil level due to incorrect oil readings, which have been attributed to a failing oil pump assembly containing internal plastic components. Because this vehicle does not have a traditional dipstick, the electronic oil level monitoring system is the only way to verify proper oil level. Due to the defective oil pump design, I am unable to confirm whether the engine has sufficient oil. This creates a serious safety concern because: •The vehicle may be operating with low oil pressure without accurate warning •Sudden oil pressure loss could cause engine shutdown while driving •Loss of power at highway speeds could result in an accident •Catastrophic engine failure could occur without proper oil monitoring This is not normal wear and tear. BMW has reportedly updated the oil pump design in newer model years to use metal internal components, suggesting awareness of a design weakness. However, no recall has been issued for 2019 models. An oil pump that prevents accurate oil level measurement and may fail prematurely presents a significant safety hazard. I respectfully request that this defect be formally investigated and that BMW be required to issue a recall to replace the defective oil pump assembly with the updated metal design.
