The engine warning system came on and warned of low oil pressure. Knowing the oil level was good I stopped the vehicle to check oil leaks. Found none. Knowing engine mechanics I assumed it was a faulty oil pump. Had it towed to BMW and told it was so. The replacement would be $8,000. Found out after lengthy research that the oil pump of the 2019 X5 (which I have) was made with plastic internal parts that would be a matter of when not if, the plastic parts would fail because the acidic nature of used oil. Presented this info to BMW and they lowered the price to $3986. 16. Then I discovered BMW knew about the problem and changed the oil pump design from 2020 on.
The electronic oil level sensor was unable to complete an oil level measurement on the idrive screen. Diagnostic inspection at a BMW dealership (mt. Kiso) and eurotech auto repair (larchmont, NY) revealed that the oil pump had degraded internally, specifically due to failure of plastic components. All sensors were working fine and showed no faults. This failure could not be detected by regular maintenance and posed a risk to engine reliability and potential sudden loss of lubrication. The car had approx 55,000 miles, was purchased purchased after my 3-year lease (original owner of new vehicle), and the incident occurred during normal use. There were no warning lights or symptoms before the oil measurement stopped working. This defect appears to be a design/materials issue affecting other similar vehicles. The failed oil pump has been replaced at my expense. I am concerned this part presents a broader safety and reliability risk and should be considered for recall.
Our 2019 BMW X5 triggered a warning light requiring us to pull over immediately and tow the vehicle to the nearest dealer. It currently has 35,000 miles and the dealer informed us that the oil pump failed. After research and discussion with the dealer this has occurred with multiple 2019 X5's at that particular dealer as well as others. BMW has not issued a recall or extended warranty for the oil pump that is included in the b58 engine. That particular oil pump has casing that is made of plastic that is known to fail. In the 2020 model they then replaced that casing with metal. It is clear BMW knows of this issue and is not taking action to ensure the consumer's safety and investment is addressed.
Fuel door does not open. BMW is fixing it under warranty. Other vehicle owners may not have an extended warrants and this fix is expensive. Not being able to put gas in your car is a serious problem. Please look into this.
