Engine And Engine Cooling Problems of BMW X5 - part 1

I am reporting a safety concern involving BMW vehicles equipped with the b58 technical update (b58tu) engine, commonly found in model years 2019–2021. These vehicles utilize a variable-displacement engine oil pump containing an internal thermoplastic adjusting component responsible for regulating oil pressure. Field failures are increasingly being reported in which this internal component fractures, resulting in sudden loss or instability of engine oil pressure. The failure frequently occurs during cold-start operation in low ambient temperatures. When the component fails, oil pressure regulation becomes erratic or is lost entirely. In many cases, drivers receive little or no actionable warning prior to engine damage or vehicle disablement. Reported precursor symptoms include inability to electronically measure engine oil level, abnormal oil pressure behavior, or sudden drivetrain malfunction warnings. Failures may rapidly progress to engine shutdown or severe mechanical damage caused by oil starvation. Loss of lubrication can cause the vehicle to become disabled without warning while driving or shortly after startup. This creates a safety hazard, particularly when vehicles become immobilized in active traffic or during winter conditions the cold is when they fail the most, where occupants may be exposed to freezing temperatures while awaiting assistance. Replacement of the oil pump requires extensive disassembly of the vehicle and repairs commonly exceed $6,000–$8,000 for just the pump, assuming the motor is unharmed. Failures have been reported across multiple production years, and affected vehicle population boundaries remain unclear. Because this condition can result in sudden vehicle disablement without adequate warning especially in the cold, I believe this issue warrants investigation as a potential safety-related defect.

Two nights ago I was at domino’s pizza. I put my car in reverse and the car died and the steering wheel locked up like the power steering was giving out I was able to start the car again, but still with no power steering assist and drove the car home about a mile away, but every time I slowed down or came to a stop sign or a stoplight, the car would die, and the battery light would flash on the dash and it would say charging malfunction once I got home we took a look at the engine and noticed that none of the belts were working at all and then I started to google what could possibly be the problem and a couple of different recalls came up recall number 12v550000 and that is engine and engine cooling engine diesel what the name of it is and the recall date is 1127 2012 and then the next one is 2012 BMW X5 diesel suvs from the model year 2012 923 BMW x fives have been recalled because they have defective engine belt, tensioners and cracks that develop along the welds if the belt tensioner fails there could be a sudden loss of power steering assist that is sounds like exactly what happened to my car and then there’s another one recall number b121918 which is from September 2019 and it is called idler pulley bolt and come to find out that actually was a recall on my vehicle, but the previous owner is the one that had it repaired so I’m not sure if BMW is willing to repair it again but there’s not a lot of miles on this cards a 2012 I bought it with 95,000 miles on it and it currently only has 131,000 miles on it. I’m just hoping for some kind of resolution here this is the fifth BMW that I bought in my lifetime and I for the most part I’ve had pretty good ultimate driving experience and good customer service and some good financing but I can’t see why just recall wouldn’t cover my vehicle. It’s currently in the shop. They’re doing a diagnostic on it and I will be getting that back later on today and I can report that back to you folks, hopefully it could be recalled. M.

Plastic oil pump cracking problem is apparently known to BMW, but they haven’t recalled these defective oil pumps leading to engine failure.

I recently took my 2019 X5 to the BMW dealership because of the recall (engine starter) and the code p0456 (nvld minor leak fault). At the same time, there's a warning that says, "oil at a minimum level. Add 1 liter immediately". I have the 3 year oil plan and asked them to put some oil, but the dealership said that they can't add oil because the oil level wouldn’t read properly. They told me they couldn’t diagnose it without charging me an extra $300 for further testing. Then, I read a lot of threads online and it seems that BMW quietly changed the pump to an all-metal design around 2020 but never issued a recall or extended warranty for the earlier cars. There's a lot of customers complaining with the b58tu engine found in many 2019–2021 Bmws (x5 xdrive40i, 540i, 340i, etc. ). The variable oil pump uses a plastic internal adjusting ring that cracks over time. When it fails, oil pressure becomes unstable or is lost, often with little warning. A common early symptom is the oil level sensor test failing and stopping around 12-20%. In the worst cases, it can lead to sudden engine damage or the car shutting down while driving. I called up my mechanic, and he said that this is a common problem and it could be an oil pump issue that needs to be replaced. I asked him for a quote and he said approximately $5k or more. I believe this is a safety defect that deserves investigation hoping for your kind consideration. I plan to keep my car as long as possible thanks, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Water pump failed while driving on highway. Completely shut down and began to smoke violently. Luckily wife was able to pull over immediately without crashing. Wife and children very disturbed. Looked up issue and 720000 BMW X5 have been recalled with same exact issue. Ours is not. Why?????.

The original b58 engine (b58b30m0, 2015–2017) utilized a conventional mechanically robust gerotor oil pump with predominantly metallic internal construction and demonstrated strong reliability in field operation. Beginning with the b58 technical update introduced for 2018 production (b58b30o1), BMW redesigned the lubrication system by integrating the engine vacuum pump and oil pump into a combined variable-displacement assembly. This redesign introduced a thermoplastic internal adjusting ring (carrier) responsible for regulating oil pump displacement through rotor eccentricity control. This component, constructed from reinforced thermoplastics including pa66-gf materials, operates within a chemically aggressive and thermally cyclic environment involving continuous exposure to engine oil additives, fuel dilution, condensation, and repeated heat cycling. While acceptable under accelerated validation testing, real-world operating conditions increasingly demonstrate premature degradation consistent with polymer embrittlement and fracture. Observed failure mode documented owner and technician reports indicate that under cold-start conditions — particularly in sub-freezing climates — elevated oil viscosity and startup load impose increased mechanical stress on the thermoplastic carrier. Fracture of this internal component allows debris intrusion into the pump mechanism, resulting in unstable oil pressure regulation. Commonly reported precursor symptoms include: • inability to perform electronic oil level measurement via idrive • erratic or oscillating oil pressure behavior • intermittent lubrication warnings or absence of warning prior to failure • rapid progression to bearing damage and engine seizure in many cases, drivers receive insufficient warning before catastrophic lubrication loss occurs. Vehicles may become disabled without notice, including during highway operation or winter driving conditions, leaving occupants stranded in potentially dangerous environ.

Safety hazard: oil pump failure leading to sudden engine stall (BMW b58tu engines) description of defect: the oil pump module in the 2020 BMW X5 (g05) contains internal plastic components that are prone to thermal degradation and premature failure. These plastic parts can crack or disintegrate, causing a sudden loss of oil pressure. Safety risk: a failure of the oil pump leads to insufficient lubrication of critical engine components, which can result in a sudden and complete engine seizure while the vehicle is in motion. This causes an immediate loss of propulsion and power steering assist, significantly increasing the risk of a high-speed collision or being stranded in dangerous traffic conditions. Additional note: this is a known mechanical defect where a critical engine component (oil pump) relies on non-durable plastic materials, creating an unreasonable safety risk for drivers and passengers due to potential catastrophic engine failure without prior warning.

On March 9, 2026, I brought the vehicle to BMW of fairfax for a scheduled appointment. In the week leading up to the visit, the vehicle intermittently failed to start and required jump-starting using a portable battery starter. Despite this issue, the car drove normally, showed no warning lights or error messages, and had approximately 69,000 miles on the odometer at the time. After jump-starting the vehicle, I personally drove it to the dealership. I paid for a diagnostic evaluation and also authorized completion of a minor recall. Two days later, I was informed that the vehicle was no longer able to shift into gear and was now completely inoperable. I was told I would be responsible for towing the vehicle off their premises. According to the service department, the vehicle now requires replacement of the eme module, at an estimated cost of $12,000. This assessment was particularly troubling because the vehicle was fully drivable when it arrived at the dealership. At no point prior to service did the car have difficulty shifting into gear. It is deeply concerning that the vehicle became a “brick” while under the care of an authorized BMW service center, with no accountability taken for what occurred during their diagnostic process.

There's currently an open recall for a number of BMW engines involving aluminum bolts in the vanos assembly that shear, strip, and break off completely. The open recall is somehow excluding some vehicles with the same exact problem like my 2011 BMW X5 xdrive35i n55 e70 with the inline 6. Currently my vanos bolts are already sheared off and sitting in my oil pan. My vehicle started misfiring and acting strange while I was traveling at 75mph, luckily I made it into a gas station and had to have it towed from there because it wouldn't start again and hasn't since. BMW knows about these hazardous bolts and chose to not repair some of them directly endangering drivers and their families. My local BMW dealership won't even confirm that the bolts in my oil pan are the vanos bolts even after I showed them photographic evidence which I still have. I've spoken with BMW north America and they said I need to get it confirmed by my local dealership, so where dies that leave me? here. . . Over $8,000 in damage/loss from an obvious manufacturer error that they are aware of!.

I am writing to report a significant safety issue associated with BMW vehicles equipped with the b58tu engine, particularly the 2019-2021 models. These vehicles feature an oil pump containing an internal plastic component responsible for regulating oil pressure. There have been numerous instances of this part fracturing in the field, leading to a sudden loss of oil pressure. The failure predominantly occurs during cold starts in low temperatures. When this occurs, oil pressure can fluctuate erratically or be lost completely, often with minimal warning. Potential warning signs include difficulties in electronically measuring the oil level, abnormal oil pressure readings, or sudden drivetrain malfunction alerts. These issues can escalate quickly, resulting in engine shutdown or severe damage due to oil starvation. This situation poses a serious risk, as the vehicle may become inoperable without warning while driving or immediately after startup. Such failures are particularly hazardous when vehicles become immobilized in traffic or during winter conditions, leaving occupants vulnerable to harsh temperatures while awaiting roadside assistance. The replacement of the oil pump necessitates extensive disassembly and typically incurs a cost of $6,000-$8,000, assuming no engine damage has occurred. A significant concern is that owners cannot easily ascertain whether their vehicle is equipped with the original plastic pump or a revised metal component. BMW's VIN-based parts lookup now indicates updated components even if the original plastic parts are still installed. Additionally, the original plastic part number has been removed from dealer networks. Failures have been reported across multiple production years, and the full extent of affected vehicles remains uncertain. Given that this condition can lead to abrupt vehicle disablement without adequate warning—especially in cold weather—this situation warrants investigation as a potential safety-related defect.

Also, BMW has actively removed the plastic part number out of all dealer networks as well. Failures have be.

While driving, the vehicle displayed a 'drivetrain malfunction' warning on the dashboard and began jerking. I safely pulled over and turned off the vehicle. Immediately after stopping, there was a distinct, strong electrical burning smell coming from the engine compartment. The vehicle was inspected by an authorized BMW dealership. The dealer diagnosed a catastrophic failure of the starter motor. The vehicle's computer logged fault codes 21611a (excessive counter-torque), 21a511 (start system: timeout), and 216119 (line disconnection). These codes confirm the starter motor suffered a severe electrical overload and thermal event. This premature failure and fire hazard identically matches the safety risks outlined in BMW's recent massive starter motor recalls (such as NHTSA recalls 25v-636 and 26v-056), but my specific vehicle is currently excluded from those recall campaigns. The starter requires complete replacement due to this overheating damage.

I'm reporting a safety issue with BMW vehicles equipped with the b58tu engine (primarily 2019–2021 models). These vehicles use an oil pump containing an internal plastic component that regulates oil pressure. This plastic part is fracturing in the field, leading to sudden loss or instability of oil pressure. Failures commonly occur during cold starts in low temperatures. When the component fails, oil pressure becomes erratic or is lost entirely, often with little to no warning before engine damage or vehicle disablement. Warning signs, when present, include inability to measure oil level electronically, abnormal oil pressure behavior, or sudden drivetrain malfunction warnings. These can quickly progress to engine shutdown or severe engine damage due to oil starvation. My vehicle is currently experiencing all of the described oil pump-related symptoms, including inconsistent electronic oil level readings and drivetrain malfunction warnings consistent with oil pressure instability. This condition creates a serious safety risk. The vehicle can become disabled without warning while driving or shortly after startup. Oil starvation can lead to catastrophic engine failure, especially at highway speeds, where sudden engine shutdown or seizure increases the risk of a crash. Failures are particularly dangerous in winter conditions, when vehicles may become immobilized in traffic or freezing temperatures. Replacement of the pump requires major disassembly and typically costs $6,000–$8,000, assuming no engine damage. Owners cannot determine whether their vehicle has the original plastic component or a revised metal version. BMW’s VIN-based parts lookup now shows only updated components even when original plastic parts remain installed, and the original plastic part number has been removed from dealer systems. Because this defect can cause sudden vehicle disablement and potential catastrophic engine failure without adequate warning.

I am submitting this correspondence as a formal notification of a potential safety-related defect affecting BMW vehicles equipped with the b58 technical update (b58tu) engine platform, most commonly model years 2019–2021. The purpose of this communication is to request immediate review under BMW’s vehicle safety defect evaluation process due to an increasing number of oil pump failures capable of causing sudden loss of engine lubrication, unexpected vehicle disablement, and occupant exposure to hazardous conditions. The original b58 engine (b58b30m0, 2015–2017) utilized a conventional mechanically robust gerotor oil pump with predominantly metallic internal construction and demonstrated strong reliability in field operation. This component, constructed from reinforced thermoplastics including pa66-gf materials, operates within a chemically aggressive and thermally cyclic environment involving continuous exposure to engine oil additives, fuel dilution, condensation, and repeated heat cycling. While acceptable under accelerated validation testing, real-world operating conditions increasingly demonstrate premature degradation consistent with polymer embrittlement and fracture. Documented owner and technician reports indicate that under cold-start conditions — particularly in sub-freezing climates — elevated oil viscosity and startup load impose increased mechanical stress on the thermoplastic carrier. Fracture of this internal component allows debris intrusion into the pump mechanism, resulting in unstable oil pressure regulation. Commonly reported precursor symptoms include: • inability to perform electronic oil level measurement via idrive • erratic or oscillating oil pressure behavior • intermittent lubrication warnings or absence of warning prior to failure • rapid progression to bearing damage and engine seizure given the potential for sudden vehicle disablement without adequate warning, I respectfully request BMW of north America initiate a formal inquiry.

Was driving at normal interstate speed when I received a warning on my dashboard to pull over and turn off engine —- low engine pressure, immediately. Call a tow. I immediately pulled over, turned off my car and contacted a tow. My vehicle was towed to the BMW dealership. I received an update that my oil pump failed. It’s almost $6k to replace and then stated not sure if that’ll truly fix the problem and to change the engine $28k. I began to do research and this is a known problem. Many owners have this problem- BMW is aware and began change the plastic part to metal in the subsequent years. I received no warning that it was beginning to fail and it is a safety hazard as I was on the interstate at the time.

I am writing to formally express my concern regarding serious and repeated safety-related failures with my 2022 BMW X5 xdrive45e, VIN [xxx] . I purchased this vehicle in 2022 through a custom build, at a purchase price exceeding $80,000, with the expectation of reliability, safety, and premium quality consistent with the BMW brand. In October 2025, while my wife was driving with my son in the vehicle, the hybrid component safety box failed without warning, causing the vehicle to stall on the roadway. This created a dangerous situation for my family. The vehicle was towed to the dealership, repaired, and returned to me on November 4, 2025. Unfortunately, on February 3, 2026, a second serious incident occurred. After my wife picked up my son from school, the vehicle began jerking violently while driving, and a strong sulphur-like odor entered the cabin. Fearing for their safety, she immediately stopped driving. The vehicle was again towed to BMW of jackson. I was informed today by the service advisor that the failure is due to another hybrid-related component, specifically the eme hybrid inverter, and that BMW north America is declining to cover this repair under warranty. These repeated hybrid system failures are deeply concerning, particularly given that both incidents involved my wife and children and posed clear safety risks. As a result, both of my children are now fearful of riding in the vehicle, and this situation has caused significant emotional distress to my family. Given the nature of these failures, the vehicle’s purchase price, and BMW’s emphasis on safety and engineering excellence, I find it unacceptable that a critical hybrid component failure would not be covered under warranty—especially following a prior hybrid system failure less than four months earlier. I am requesting that BMW north America review this matter promptly and provide a reasonable resolution, including warranty coverage for the eme hybrid inverter repair.

The contact owns a 2019 BMW X5. The contact stated that while driving approximately 45 mph, the red oil light suddenly illuminated and the messages "stop carefully and turn off engine", “engine oil pressure too low", "continued driving will result in engine damage". The vehicle was towed to the local mechanic, who discovered that the engine oil was black and thick. The vehicle was later towed to the local dealer, who confirmed that the engine oil was thick and dark, and the engine needed to be replaced. The failure mileage was 85,000.

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 NHTSA directly with BMW. P.

BMW knowingly did not notify it's 2019 BMW X5 m40i (engine b58) vehicle owners. This is in reference to the faulty design and made plastic engine oil pump. It has been known to fail prematurely due to weaken parts. Some analysis done was from certain oil viscosity's applying additional unneeded stressful pressures. This later was recognized by BMW and a newer design and/or metal sturdier one had taken it's place in subsequent model years starting in 2020. Some owners were able to remediate the oil pump failure and new replacement either covered under intact warranties, and some were covered through quieter negotiations with BMW customer care's authorizations. To my understanding, no recalls were made nor were any techical service bulletins (TSB) made to it's owners. I don't see how BMW can be allowed to get away with an issue of safety which could cause a catastrophic failure of the affected engine? under the circumstances, BMW should be fully reimbursing me for the repairs here, and be glad there were no serious injuries or worse, deaths! I have been in contact with their customer care and nothing has been done to date.

While driving through west los angeles, the vehicle suddenly began emitting white smoke from the engine compartment. There were no prior warning lights, messages, or symptoms indicating a problem. The smoke quickly intensified and turned dark. Thick smoke filled the air, and the cockpit, with the smell of toxic fumes. I safely maneuvered to the shoulder and exited the vehicle with my passenger. Flames erupted from the front of the vehicle. We called 911, which dispatched the fire department. The lafd responded, cutting open the hood in order to extinguish the fire. The vehicle was towed to a yard following the incident. The vehicle and its contents were declared a total loss.   bwm north America dispatched a technician to inspect the vehicle. After inspection, the manufacturer indicated that the starter was the source of the fire. At the time of the incident, the vehicle was subject to a safety recall related to the starter with no remedy available. The failure occurred without warning. Both occupants were exposed to heavy smoke.

Engine starter overheating. Car won't start until engine cools down. Car would not let my shift into neutral in order to move to a safe location. Was stuck in front of several cars in an unsafe location. No warning message showed up. Car was just inspected and serviced with no indication that this was a problem. Car taken to dealer after incident and inspected produced the same results.

The contact owns a 2021 BMW X5. The contact stated that while driving at undisclosed speeds, unknown warning lights illuminated on several occasions. The failure had occurred while driving and while restarting the vehicle. The vehicle was taken to a dealer, where it was diagnosed, and determined that the starter had failed and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA hotline for further assistance. The approximate failure mileage was 44,000.

During a trip out of town, I saw a warning light that informed me that the engine coolant level was low and that scalding could occur. The next morning, my husband checked the coolant levels and added coolant to the reservoir. Later that day, I received the same warning message. The vehicle was leaking coolant and could not sustain the appropriate levels. We brought the vehicle to the local BMW dealership and was told that the coolant pump had broken from the inside and would need to be replaced.

Oil leaking from the valves cover onto the manifold and could cause a fire. I have replaced the valve cover on 11/03/2022 miles 107698 I pay 1493. 21 for the repair. Last week 12/23/2025 the same thing started again. The oil is leaking again on manifold the car is smoking I am afraid to drive the car. I believe I should not be paying again for the same problem.

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.

The component that failed appears to be the hybrid propulsion and charging system, including the high-voltage battery management system and/or integrated charging electronics. The vehicle will not accept a charge from any home or public charging source. The high-voltage battery was replaced approximately one year ago; however, the charging failure persists. The vehicle is available for inspection upon request. In addition to the charging failure, the vehicle displayed drivetrain malfunction and start/stop malfunction warnings. While driving on the highway at normal speed, the vehicle lost power and stopped, creating a hazardous situation in active traffic. This sudden loss of propulsion placed my safety and the safety of other drivers at risk, as surrounding vehicles were traveling at highway speeds. Prior to the failure, warning messages appeared intermittently, including charging system faults and start/stop malfunction alerts. These warnings began approximately one year ago around the time the charging issue started. The vehicle was previously serviced and the high-voltage battery was replaced; however, the underlying issue was not corrected. The root cause is unknown, but the symptoms suggest a failure within the hybrid control system, charging module, DC-DC converter, or related electrical components. The failure has been persistent and unresolved. I am concerned that defects within the hybrid propulsion system may lead to additional sudden loss of power events.

The contact owns a 2014 BMW X5. While the contact's daughter was attempting to start the vehicle, the vehicle failed to start. The vehicle was towed to an independent mechanic, who diagnosed the vehicle and determined that the 12-volt battery and the auxiliary battery needed to be replaced. The vehicle was repaired; however, the contact attempted to start the vehicle, but the vehicle failed to start. The vehicle was towed to an independent mechanic who specialized in foreign-made vehicles. The vehicle was diagnosed, and it was determined that the water pump was constantly running and was draining the 12-volt battery. The mechanic determined that the water pump needed to be replaced. The vehicle was not repaired. The contact researched online and related the failure to NHTSA campaign number: 24v608000 (engine and engine cooling, electrical system); however, the VIN was not associated with the recall. The manufacturer was informed of the failure and referred the contact to the NHTSA hotline to report the failure. The failure mileage was approximately 160,000.

The contact stated that during the inspection of the vehicle, the dealer discovered that the water pump was beginning to leak coolant onto electrical circuits, inside the engine compartment. The dealer recommended the water pump replacement. The vehicle was not repaired. The manufacturer was not informed of the failure. The contact related the failure to NHTSA campaign number: 24v608000 (engine and engine cooling, electrical system), however, the vehicle model year was not part of the original VIN selection. The failure mileage was approximately 21,000.

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.

The safety risk arises from inaccurate federal recall records maintained by BMW of north America. My vehicle had a safety recall for starter replacement (recall 25v-644). This recall repair was already completed by an authorized BMW dealer, and the starter was replaced under warranty. However, BMW continues to list the recall as open with “remedy not available. ” this creates a safety risk because inaccurate recall records may lead to improper vehicle safety status, incorrect regulatory reporting, and potential refusal of assistance if a starter-related failure or no-start condition occurs in the future. The problem has been confirmed by an authorized BMW dealer, and I have official service documentation showing that the recall repair was completed. The vehicle was inspected and repaired by BMW of gwinnett place. No warning lights were present after the repair. This complaint is not about a new mechanical failure, but about BMW’s failure to accurately update and close a completed safety recall, which misrepresents the vehicle’s safety status.

The contact owns a 2020 BMW X5. The contact stated while driving approximately 25 mph, the message "low oil pressure - stop vehicle immediately" was displayed, and the oil warning light was illuminated. The vehicle was pulled over to the side of the road and turned off. The vehicle was towed to a dealer where it was diagnosed and determined that the oil pump was inoperable and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 81,000.

I am reporting a serious safety defect involving the oil pump assembly on my 2019 BMW X5 xdrive40i. While driving at low speed in normal conditions, a sudden dashboard warning appeared stating: “engine oil pressure too low — stop carefully. ” I immediately pulled over and shut off the engine. My vehicle had been serviced by an authorized BMW dealership less than one week earlier, and no faults or issues were identified. There were no warning signs or symptoms prior to the failure. An independent licensed repair facility inspected the vehicle after the incident and confirmed that the oil pump had failed due to a defective plastic internal component used in the pump’s design. The failed parts are available for inspection upon request. This failure created a significant safety risk, as sudden loss of oil pressure can cause engine seizure, loss of power steering, loss of braking assist, and an inability to safely control the vehicle. Had this occurred at highway speeds, the consequences could have been severe. I have since learned that this exact issue has been reported by other owners of 2019 BMW X5 vehicles and other BMW models using the b58 engine, which were equipped with an oil pump containing plastic internal drive components prone to cracking or separating. BMW appears to have updated the oil pump design to a metal version in 2020 and later models, suggesting the manufacturer was aware of the weakness of the earlier design. The defect was confirmed by an independent service center. The vehicle had also been inspected by BMW one week prior during scheduled service, yet no issues were detected. Because this failure presents a clear safety hazard and appears to be related to a widespread design flaw, I respectfully request that NHTSA open an investigation into the oil pump used in 2019 BMW X5 vehicles and consider issuing a safety recall.
