Filed Sep 17, 2026 · Engine · NY

Engine oil pump failure. The housing for the oil pump is made out of plastic and know to fail due to the part turning brittle in the engine surrounded by oil and heat. The oil pump housing has cracked causing a failure at the pump housing. The results are catastrophic engine failure as well as not being able to read engine oil levels on bmw idrive system.

The engine oil pump failed internally. The vehicle is equipped with a factory-installed variable-displacement oil pump that utilizes an internal thermoplastic adjusting ring. Due to heat cycles and mechanical stress, this plastic component degrades, becomes brittle, and catastrophically shatters or cracks.The first symptom appeared when the vehicle became entirely unable to complete an electronic engine oil level measurement via the iDrive system, consistently freezing and aborting the test at approximately 15% to 20%. This defect directly compromises road safety. A sudden drop in oil pressure causes severe internal engine friction, leading to immediate engine seizure or a total loss of motive power without adequate warning. Experiencing a sudden engine stall while driving at highway speeds places the driver, passengers, and surrounding motorists at extreme risk of a high-speed rear-end collision. Furthermore, a total engine shutdown disables power-assist steering and braking, making the vehicle incredibly difficult to control and maneuver to safety. Catastrophic mechanical failure from oil starvation also presents a severe under-hood fire hazard if oil leaks onto hot exhaust components.The problem has been officially reproduced and confirmed. The vehicle was brought to Bavarian Werkstatte, where certified technicians diagnosed the issue as an internal structural failure of the variable-displacement oil pump's plastic adjusting ring. The component is currently available for inspection upon request. BMW is fully aware of this defective design. They updated this exact component in mid-2020 to an all-metal oil pump to prevent plastic fragmentation. Despite knowing that the 2019 thermoplastic rings degrade, become brittle, and shatter under normal operating heat cycles, the manufacturer has failed to issue a safety recall in the United States, leaving drivers exposed to dangerous sudden engine failure.

I am reporting a safety concern involving a 2019 BMW X5 that experienced a sudden and catastrophic engine failure at approximately 75,000–80,000 miles. The failure occurred without any prior warning indicators, dashboard alerts, or fault codes. The vehicle lost engine function and required inspection by an authorized BMW dealership. The dealership documented internal engine damage, including metallic debris in the oil system, oil contamination, and bottom-end engine knocking. A full engine replacement was recommended. This raises safety concerns because: The failure occurred without warning Sudden engine failure could create hazardous driving conditions depending on speed and location There may be a broader pattern of similar failures BMW of North America has denied assistance and has not provided any explanation for the cause of the failure. I am submitting this complaint so the incident can be recorded and evaluated as part of any potential defect investigation.

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.

Premature oil pump failure. 2019 BMW x5 with only 46k miles has been diagnosed with an oil pump failure. Vehicle needed to be quickly pulled over and shut off to avoid catastrophic engine failure or engine seize. If this happens on the highway or at any speed the vehicle will lose power and be unsafe to control likely ending in an accident. This is a known Issue. BMW produced the vehicle with a flawed oil pump design that has a plastic ring around the impeller. The ring deteriorates and cracks leading to pump failure and loss of oil pressure It is only on limited models early 2019 X5. BMW redesigned with an all metal pump quietly. This issue needs to be addressed with BMW as it is unsafe for these family vehicles to be on the road with such a significant risk to its passengers and others. The failure happens with little to no warning. When contacting BMW they told me they would not consider helping with repairs. The repair for this part is upward of $8k which in turn will likely limit consumers ability to fix proactively. This is totally unacceptable and needs to be addressed by the federal safety agency directly with BMW. P

Parking brakes can only be applied but cannot be released due to faulty design of the parking switch. This will cause the vehicle not able to move or be towed in an emergency especially when an engine failed to start. This problem confirmed by an independent repair shop and also has highlighted in several BMW group chats.

while stopped in traffic on a freeway in fast lane, the vehicle was in the "stop/go" mode. When I pressed the accelerator, the engine failed to start. On multiple attempts engine would not start and I could smell electrical burn. The CHP was on site and we attempted to push the car to the side and out of the fast lane. However, since the engine would not start, there was no way to shift the car into Neutral gear. This is a design flaw and could lead a serious injury of fatality if the drive is stuck on the freeway and unable to move car. Even with Tow Truck, the car had to be dragged onto the truck bed. This is related to recall no. 25V‑644. The recall should be elevated to "critical" status.

The oil pump contains a plastic housing that fractured during regular use. (Yes, I did retain the part for inspection and can include photos of the defect here). Yes, the problem has been confirmed by my mechanic and the general public with multiple posts and videos shared widely across the internet and in vehicle forums. This failure caused the engine to lose oil pressure abruptly. Had this occurred at highway speeds or in heavy traffic, it could have resulted in a serious accident. BMW is aware of the problem and has redesigned the oil pumps for all X5s starting in 2020. There is no real warning for this potential failure which would cause the engine to cease. The problem is most commonly diagnosed by checking the oil level via the I-Drive System electronically, (there is no dipstick for these cars). The oil level cannot be provided on the screen due to significant pressure fluctuations caused by the damaged oil pump- and that's how you know you're at risk of engine failure. There has been no recall for the 2019 vehicles. All 2019 BMWs with the B58 engine, (and the Toyota Supra), include this dangerous and expensive design flaw and I believe a recall should be issued; the majority of these cars are still on the road. I estimate the total number of cars to be 250,000 cars. My oil pump had to be replaced or the car would be rendered undriveable. The estimate from BMW dealership #1 exceeded $11,000; the estimate from BMW dealership #2 exceeded $8,000. The car has less than 70,000 miles on it and this is a known issue for this model year.

I have a 2019 BMW X5 that experienced engine failure and required a new battery and starter to be installed. I feel certain that it is related to a recall on some 2019/2020 models but my vin is not included. [XXX] I received a fault warning for drivetrain malfunction. I took the car to the bmw dealership and was told it was an upper radiator blind failure and had it replaced. The dealership performed a software update per recall SIB 120524. The mileage was 36,981. While visiting family in New Orleans[XXX] @ [XXX] in the afternoon, on Decatur (heart of French Quarter) the car died in the middle of rush hour traffic. Fault came up that said ”engine overheat will attempt restart in 180 sec.” Car would not start and had to be towed to local BMW. Highly stressful as I was with my daughter. We had people honking horns, screaming at us, police threatening to ticket us, etc. ordeal lasted 2 hrs until tow arrived. After 4 days in the BMW shop I was advised a new battery was needed. No indication the starter was checked at this time. Mileage was 40,168. The next day [XXX] when driving home to Dallas I pull over to get gas in Natchitoches, La. I fill up and try to start car and failure notice shows up ”engine overheat will attempt restart in 180 sec”. Same thing as before new battery installed. The car did not restart even after an hr of waiting. Would not take a jump so we had to be towed to Shreveport(1 1/2 hrs away) to closest BMW dealership. I was traveling with My son and was beyond grateful at the kindness of the tow driver as he took us to get food and a hotel that was safe after delivering the car to the dealership. The next afternoon the Shreveport dealership determined that the starter failed and it had to be replaced. Mileage was 40,423. I feel I am due repayment for the tows and repairs on what I feel are recall related. I have contacted all 3 dealerships and North America BMW to get the run around. No one wants to take accountability! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO
