NHTSA complaint #11758461 — an unverified report by a vehicle owner.

ENGINE

I was driving at 70 mph on the highway when the car suddenly and without warning went into neutral, lost all functionality, and displayed the warning "Drivetrain Malfunction--Stop Driving Immediately--Call Roadside Assistance." I had to drift (barely) to side of a busy highway and exit the vehicle to get to safety. The dealer review of fault codes include: High-voltage system: No voltage established; No communication possible with: Accumulator-management electronics; SME: Software action required; Function: Acceleration not possible; Function: It is not possible to establish the drive-ready state; Drive function: Repair measure will soon be necessary. This happened on XXX around noon on XXX in [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE

The front driveshaft universal joint failed causing the drive shaft to bust a hole in the engine and crack the transmission. There was no knocking noise prior to failure. It suddenly failed, disengaged and caused damage. I was told by service manager the u-bolt must have been defective to have failed without warning.

I am reporting a recurring catastrophic high-pressure fuel-pump/fuel-system failure in my 2018 BMW X5 after BMW previously repaired the same type of failure, and subsequently performed the NHTSA HPFP recall on my vehicle. I am a 71 year old driver. This was a repeat catastrophic failure after Recall 21V-586 was performed and the loss of propulsion on the freeway was terrifying, and I almost crashed into other cars! At 42,763 miles, the vehicle experienced a catastrophic failure while being driven. The vehicle shut off while driving and would not restart. Santa Monica BMW documented a “HIGH PRESSURE FUEL PUMP MALFUNCTION” and fault codes. BMW's technician followed the fuel-system test plan and reported that the fuel quality control valve had metal shavings. See Invoice 42,763.pdf BMW subsequently issued NHTSA Recall 21V-586 concerning the HPFP on affected BMW diesel vehicles, including my vehicle. BMW performed the recall repair at Weatherford BMW at approximately 58,292 miles. The repair order identifies the work as “PERFORM RECALL B130121 HIGH PRESSURE FUEL PUMP” and documents replacement of the high-pressure fuel pump. See Invoice 58,292. At 120,945 miles, the vehicle experienced another, similar catastrophic failure while I was again driving on a freeway. Weatherford BMW subsequently diagnosed multiple fuel/rail-pressure faults. The technician removed the fuel quantity control valve to check for swarf and found magnetic metal shavings in the fuel system. See Invoice 120,945 These failures are particularly concerning to my safety. I am submitting this complaint to the NHTSA because I believe the recurrence of a catastrophic system failure, including metal contamination and loss of propulsion, after BMW previously replaced the complete fuel system under warranty and subsequently performed the HPFP recall remedy, warrants investigation to determine whether the recall remedy or the underlying HPFP/fuel-system defect can cause a subsequent failure of this nature.

2023 BMW X5 had a defective water pump replaced under warranty at 27,585 miles on 9/12/2024. Today 8/10/2026 at 52,907 miles the water pump again needs to be replaced. BMW has had water pump recalls in the past for similar years of x5 SUV, but our VIN is not included in the current recalls. Photographs of the recalled water pumps look exactly like our pictures. I believe the recall should be expanded to include additional BMW models/VIN ranges.

ENGINE

My 2019 BMW X5 (G05) equipped with the B58 Technical Update (B58TU) engine has experienced a failure / is showing early signs of failure of the engine oil pump assembly.Beginning with the B58TU engine, BMW utilized a variable-displacement oil pump that contains a thermoplastic/plastic internal adjusting ring. This plastic component degrades under normal operating temperatures, resulting in a sudden mechanical failure of the pump. This failure leads to a sudden drop in engine oil pressure, vehicle disablement without sufficient warning, or an inability for the iDrive infotainment system to complete an electronic oil level measurement.A sudden loss of engine lubrication while driving presents a severe safety hazard, capable of immobilizing the vehicle in active traffic. BMW has updated this exact pump part number to utilize all-metal internal carriers on later production runs, but refuses to cover the cost for early out-of-warranty models. I am requesting that the NHTSA open a safety defect investigation into the early B58TU oil pump assembly to force a mandatory safety recall.

The contact owns a 2010 BMW X5. The contact stated that while driving at an undisclosed speed, the vehicle stalled and was pulled over to the side of the road. There was no warning light illuminated. The vehicle was towed to be repaired under NHTSA Campaign Number: 23V707000 (Engine and Engine Cooling); however, after the recall repair was performed, the vehicle failed to start. The contact stated that the recall repair indicated that a diagnostic test was required to determine that an engine failure was a direct result of a fractured VANOS bolt. The contact stated that the dealer declined a diagnostic test or the repair. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 135,000.

It’s a common issue between 2019-2020 where the oil pump which came from factory has plastic impellers which crack/disintegrate causing catastrophic failure to the engine disabling the vehicle the only warning signs before this happens is you cant read oil level and or the car prompts with a warning low oil messages if untreated the car will have catastrophic engine failure with little to no warning the car was mass produced and this is a common issue therefore should be recalled

ENGINE

I was shocked by the failure of the oil pump on my 2019 BMW X5. Furthermore, through my research and discussions within the BMW community, it is evident that this specific oil pump associated with 2019 engine component has a documented history of premature failure and known defects (plastic). Given that this is a known vulnerability rather than standard wear-and-tear, I do not believe that I should bear the full burden of such an exorbitant repair cost of $6890. Why is issue has not been recalled by BMW??

Low oil pressure light came on during interstate drive. Later analysis at dealership revealed this is related to faulty oil pump with plastic parts in B58 engine.

I replaced my starter prior to a recall that was issued. After the recall, I submitted a claim for reimbursement and the check was issued. Bmw of North American has not updated the recall information associated with my vin. I am this unable to list my vehicle on any rental platform as it is showing a status of an open recall for the starter. The repair was done in September, 2025 and I was reimbursed 3 weeks ago.

NHTSA complaint #11749940 — an unverified report by a vehicle owner.

ENGINE

I always service and baby my vehicle. Had recently got starter recall & fresh oil change done 2 months at my local BMW Atlantic City NJ dealership. On June 27th, as I was driving the vehicle normally a message popped on the dash stating engine oil is at a minimum level, add 1 liter of engine oil, refill oil immediately. So I went to my earliest autozone bought quart of mobile 1 oil and refilled it. After that the warning message went away and came felt fine. Unfortunately the next day same message popped up, so drove over to BMW service to get diagnosed. Due to the computer system in the vehicle not being able to read the oil level measurement. It would go from 0-18% oil level reading then message would pop up saying unable to read to try again or make sure vehicle is on ground level which I made sure it was. So next day I dropped it off at BMW dealership for diagnosing. After 1 day and half they came to the conclusion that it is a bad oil pump and wants to charge $6,362.31 for repairs. Advisor stated its due to older gen bmw b58 engines using plastic oil pumps inside which causes to break and cause leaks. So they are aware its an common issue but won’t do an recall or service bulletin to fix issue which is very dangerous because the engine could seize up and stall anytime I’m driving around due to not knowing the oil level measurements. It is super risky and unfair for consumers to pay for such a big bill repair. I hope there is recalls or something to help remedy this cause for current & future BMW affected vehicles. BMW is aware of this issue but won’t resolve it.

ENGINE

I purchased my vehicle around Labor Day of 2020. I still own and operate the vehicle. Since I have owned my vehicle, I have repeatedly been told my turbos are leaking oil, etc. I have even had several oil leaks repaired on my car. Fast forward six years, and I am buying 5 quarts of oil every two weeks and topping up the oil in my vehicle every week, at least 2-3 quarts per week. I also have smoke coming out of the tail pipes intermittently. The car also smells like it is burning oil, but there are no visible oil drips on the ground currently. I discovered by research there have been two lawsuits: Isley v. BMW of North America LLC, et al., Case No. [XXX] in the U.S. District Court for the District of New Jersey ([XXX] [XXX]), and Bang v. BMW (Original [XXX]) ([XXX]). I have had repeated documented repairs and I never received a notice for these cases. I need my vehicle repaired and I need BMW to take ownership of this defect. I never received one notice regarding these lawsuits, or I would have had my vehicle repaired. I only have 102,000 miles (currently), so my vehicle should be covered in terms of mileage.

I am having issues with the starter motor / battery. I have read extensively about issues with BMW X5 models having recalls during the production period of my vehicle. BMW is trying to charge $3,000 for a new starter and battery. I feel that this is a known and significant issue with BMW X5 vehicles produced during the same period as my vehicle and would like for this to be covered under recall.

NHTSA complaint #11746875 — an unverified report by a vehicle owner.

ENGINE

My vehicle has suffered catastrophic electrical failure due to water intrusion directly into the rear cargo compartment. This water ingress has destroyed vital electronic control modules that were designed and placed in low-lying, unsealed body cavities—an engineering layout heavily documented as a design vulnerability in the E70 chassis. My safety was put at risk as this happened on the highway and threw my SUV into limp mode. I could not drive the speed limit on the highway and had to drive home with my hazard lights on while cars drove around me and almost collided with me on the highway. BMW has previously acknowledged the severe liabilities of placing sensitive electronics near drainage paths, as seen in the Catalano v. BMW of North America litigation. This is not a wear-and-tear issue; it is a design failure that leaves critical safety components swimming in water during normal rain events.

ENGINE

I took my 2022 BMW X5 xDrive 45e for concerns of shuddering at low speeds and tight turns under warranty. No warning messages on dashboard. I asked specifically what was causing the shuddering. BMW of Raleigh would not respond. But they found that the Transfer Case was affected so they flushed the oil and put an oil mixture replacement in. According to the most recent BMW service bulletin, the technician is only to put in DTF oil. The technician not only put in DTF oil but also an over-the-counter non-approved chemical additive. Reading the service bulletin, the Transfer Case is supposed to have a lifetime warranty. We were charged over $500 for this "oil change", but it was under warranty. Transfer Case failures can result in accidents on highways and other roadways and complete mechanical failure of vehicle.. The oil change did not fix the Transfer Case issue but extended out the vehicle so that it now falls out of warranty. A TC replacement will cost $10,000 or more out of pocket. TC issues is a known BMW issue since 2018. Lawsuit has begun w/thousands of plaintiffs all over USA w/ 2019-2025 BMWs because they refuse to acknowledge that they are at fault even though they continue to put out bulletins for this exact issue. BMW has made sure that Transfer Case is not on any warranty they offer.

Oil pump with plastic parts failing

NHTSA complaint #11745369 — an unverified report by a vehicle owner.

ENGINE

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.
