Description of the complaint: I own a 2022 BMW X5 (VIN: [xxx], current mileage: approximately 39,500 miles as of 08/24/2026) equipped with the b58tu engine, which uses a plastic oil pump (part number 11418646454) rather than a metal one. I have not yet experienced an actual failure, but I am reporting this as a precautionary safety concern based on the following: 1. On BMW's official parts reference site (realoem. Com), the oil pump for my specific vehicle is flagged with an "attention! observe puma measure 65494813" notice, indicating BMW's own internal system has identified a known issue requiring special observation for this part. 2. I have learned that BMW korea has acknowledged this plastic oil pump issue following a government investigation, and has committed to a full free repair program for affected vehicles in korea. 3. I am aware of multiple reports and complaints from other b58tu engine owners in the united states regarding this same plastic oil pump issue. 4. Given that the oil pump is a critical component for engine lubrication, a failure of this part while driving — particularly during highway or long-distance travel — could pose a serious safety risk, including sudden loss of engine oil pressure and potential engine seizure at speed. I am filing this report to bring this issue to NHTSA's attention before an actual failure occurs, and to request that this be considered as part of any pattern analysis regarding b58tu engine oil pump defects in the united states. - **year:** 2022 - **make:** BMW - **model:** X5 - *:** [xxx] - **mileage:** 39,500 - **component:** engine and engine cooling (or "engine oil system" if listed separately) - **attachments:** realoem.

The high-voltage battery system (this is a plug-in hybrid) began intermittently displaying a "battery not properly charging" warning approximately 6 months ago; the issue would resolve after plugging in and charging. On July 14, 2026, while driving, the vehicle displayed a "critical battery failure - pull over immediately and drive slowly" warning. The driver pulled over and shut off the vehicle; the warning cleared and the car appeared to drive normally afterward. This warning recurred several times over the following weeks under the same pattern. On August 6, 2026, the same critical battery failure warning appeared while driving; this time steering feel and drivetrain response were abnormal, and the air conditioning and several electronic features stopped working. Our safety, and the safety of other drivers on the road, was put at risk by the sudden loss of full vehicle control while in motion. The vehicle has been at an authorized BMW dealership for inspection since August 7, 2026; a full diagnosis is pending. Dealer service staff independently remarked that two other BMW x-series plug-in hybrids came in that same morning with the identical warning and symptoms, suggesting this may be a widespread component defect rather than an isolated issue.

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.

My 2022 BMW X5 is having the transfer case star to fail. Where the symptoms currently are at is the car has a shudder in certain situations. I can feel it when maneuvering at slow speeds and I can feel it at times at speed or when on a steep hill. I bought the extended warranty for the car and the maintenance package for the vehicle. I'm at 68k miles and the shudder started before that but I am still covered under extended warranty. I have had all maintenance done on the vehicle at the local BMW dealership including all tire needs and have always replaced tires as necessary and number of tires at a time they suggest. When I took it in as the vehicle is reporting needing brakes 2 weeks ago, I mentioned the shudder and asked about tire tread on the 2 front tires. They came back with that the tires were fine in spec with the back 2 but that shudder is the transfer case. The dealer also then mentioned a couple things: - they now recommend changing the fluid in the transfer case by 60k miles due to amount of failures they are seeing (my X5 was in the dealership multiple times before an after 60k and it was never recommended). - that since it is not in the recommended maintenance for the xdrive4. 0i that the car would not alert to have it changed and therefore BMW would not cover changing the fluid under the ultimatecare (service maintenance plan they sold me). That the transfer case was meant to be a for life fluid. - I asked what happens next if the fluid is not changed, that it will continue to degrade and once it fully gives out the vehicle will become inoperable - I asked does the fluid change save the transfercase and they said it seems to help many vehicles and the shudder disappears but for some it does not. - I then asked would the BMW extended warranty purchased cover it if it fully failed or the fluid change did not solve the shudder and I was told maybe fully, partially or not at all. Ext warranty brochure says it is covered at platinum level I hav.

The driveshaft malfunctioned which caused the vehicle to lose control. Yes, it is available at the repair shop. Wife was driving with mother-in-law and [xxx] child at highway speeds (55) requiring her to maintain control and pull over without getting hit by other cars. Independent repair shop confirmed the driveshaft failed and took out the transmission and transfer case. No warning/engine lights or other indications of any issues. Reading online confirms this to be a case for these vehicles - here is one example [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am writing to formally document serious and recurring safety concerns with my certified pre-owned 2024 BMW X5e, which I purchased from BMW of sterling on xxx. On xxx I was merging onto [xxx] during morning rush hour when my vehicle suddenly lost power and shut down in the middle of traffic. The vehicle first displayed a yellow drivetrain warning indicating that I could continue driving at reduced power to the nearest service center. Almost immediately afterward, a red drivetrain warning appeared instructing me to seek service immediately. At that point, the vehicle would not restart and continued displaying the error message. Having a vehicle suddenly become disabled in the middle of a major interstate during rush-hour traffic was both frightening and extremely dangerous. I contacted BMW assist but was transferred among several representatives without receiving meaningful assistance. Vdot ultimately responded, and the vehicle was towed at my expense to BMW of sterling. Ultimately, I was informed that BMW of sterling could not identify the cause of the failure or replicate the problem. I was told that BMW in germany had been consulted and that the vehicle's electronics had been reset. When I picked up the vehicle, I specifically asked whether it had been tested in electric, hybrid, and sport modes and was told that it had. However, my BMW app indicated that the vehicle had not been charged since before I brought it in for service, which raised concerns for me about the extent of the testing that was performed. On xxx, I drove the vehicle to [xxx], for work. When I returned to the vehicle that afternoon and attempted to start it, I received the same drivetrain warning messages. After approximately 15 minutes, the vehicle eventually started normally, and I was able to drive home without further incident.

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.

We live in [xxx]. We own a 2021 BMW X5-45e. It has about 85,000 miles and has always been serviced by the BMW dealer here in [xxx] – pierce BMW. On the evening of xxx I drove the vehicle home at 6:30pm after a 30 mile drive and parked the car outside in the shade of our house. The temperature at the time was approx. 95 degrees f. At 6:45pm we left the house and drove on the freeway and city streets of [xxx] about 8-10 miles to see a concert in downtown [xxx]. The temperature at that time was about 90-92 f. There was no wind. We then parked outside the venue for about an hour and watched the concert. We came out of the concert at about 8:30 and started the car. I drove about 200 feet to the corner and stepped on the brake. As the car slowly came to a stop the emergency/parking brake suddenly engaged at about 2-3 miles per hour. The car jerked to a very sudden and violent stop. To get the car going, I had to disengage the parking brake which was on with the indicated brake light. The engine was still on and there were no warning lights flashing. I turned the corner and accelerated again to about 15 miles per hour and touched the brakes to bring the car to a stop. The same thing happened. The car jerked to a sudden stop. To get the car going, I had to disengage the parking brake. The engine was still on and there were no warning lights flashing. It also happened a third time. That time, my elderly wife complained of pain in her back. After the third time, I turned the engine off and waited about one minute. I then restarted the car and drove it home with no problems. We have had no further issues, but this is a big concern as we no longer trust the car to perform as expected. This is a very worrisome issue and would like some answers, but apparently none are forthcoming. I took the car to pierce BMW and they could find no fault code or problem.

My 2026 BMW X5 xdrive50e experienced a serious freeway safety event involving loss of braking/brake power, loss of vehicle power/functionality, and multiple vehicle warnings/errors. The incident occurred while I was driving on the freeway and substantially affected my ability to safely operate the vehicle. BMW emergency services subsequently towed the vehicle to irvine BMW on 07/09/2026. Irvine BMW later attributed the event to emergency stop assist (esa) and the driver monitoring system (dms), rather than identifying a mechanical brake failure. Its written explanation states that esa can take over vehicle guidance and decelerate the vehicle using multiple short braking jolts. The dealership reported a stored dms fault but stated that it could not duplicate my reported condition. I have not been provided evidence that the original freeway event was reproduced or that its cause was conclusively established. Irvine BMW initially represented that material covering the display was an aftermarket screen protector and stated that BMW technical required its removal because it could interfere with the dms camera. On 07/27/2026, the general manager apologized and confirmed that the material was actually original BMW transportation protection film. The dealership also proposed reducing esa sensitivity as an alternative. I remain concerned that the combination of loss of braking/brake power, loss of vehicle power/functionality, and the reported esa/dms behavior may represent a serious safety defect or malfunction affecting braking, vehicle control, or driver-monitoring systems. I kindly request that NHTSA review this reported safety event, including esa, dms, related vehicle-control systems, and the interaction with the display/driver-monitoring system, and determine whether further investigation is warranted. I can provide dealership records, BMW app data, communications, and diagnostic documents.

I am reporting a front differential/front drive axle failure and a separate steering wheel/steering column adjustment issue. The vehicle was brought to an independent BMW/german repair shop for a routine oil change/inspection. The shop advised me that the front differential/front drive axle assembly had failed or was severely damaged and needed repair/replacement. The vehicle/component is currently at the shop and should be available for inspection upon request. I am concerned this could put my safety and others at risk because the front differential is part of the awd drivetrain. If it fails further while driving, it could affect drivability, traction, or vehicle control, especially at speed or in poor road conditions. The issue has been confirmed by an independent service center. To my knowledge, it has not yet been inspected by BMW, police, insurance, or government reps. A third-party warranty inspector may inspect it before repair. The exact cause is unknown. I was told BMW appears aware of this issue because the replacement part has a newer/superseded part number. This suggests BMW may have revised or updated the original part. I do not know if BMW has formally acknowledged a defect, but I am concerned this may be a broader issue given the low mileage. Separately, the power-adjustable steering wheel/steering column sometimes makes a grinding/vibrating noise when I start the vehicle and the wheel automatically moves out/down into the driving position. There were no warning lamps or dashboard messages. The exact date it first appeared is unknown, but it has occurred more than once. I previously raised this type of issue with a BMW dealer and was told it was a known issue. The exact cause is unknown. I am concerned it could involve the steering column adjustment mechanism or related components. I am reporting both issues because the vehicle is low mileage and I am concerned they may be safety-related defects rather than isolated maintenance items.

On July 8, 2026, the vehicle unexpectedly stalled while I was driving in the middle lane on the I-95 highway, creating a safety concern. There was complete loss of engine power and low power to steering. The vehicle had to be towed to BMW of peabody, massachusetts. The vehicle had 30850 miles during the incident. During the inspection at service centre, I was informed that the safety fuse box and 12v auxiliary battery had failed which stalled the vehicle.

On July 6, 2026, while my brand-new vehicle (purchased June 10, 2026) was stationary and preconditioning, the high-voltage drivetrain and climate control networks suffered a catastrophic synchronization failure. The vehicle’s internal communication bus network completely crashed, causing the sme (battery management system) and ihka (climate control) modules to stop communicating. This software/hardware network dropout left the high-voltage electric ac compressor running entirely unmonitored. As a direct result of this uncontrolled loop, the undercarriage of the vehicle physically froze into solid blocks of ice, fluid rapidly dumped onto the pavement, the malfunction indicator light illuminated, and the battery management system triggered an emergency hard-fault safety lockout. This digital lockout instantly stripped away 75% of the high-voltage battery's usable range, dropping it from 38 miles to 9 miles in a single millisecond to prevent a catastrophic thermal event. During this component failure, the high-voltage compressor was audibly grinding and suffering heavy mechanical strain due to liquid refrigerant slugging. This presents an extreme, unreasonable public safety risk. A sudden high-voltage network crash and sudden loss of 75% of battery range while driving on a highway would result in an instantaneous, uncommanded drop in vehicle propulsion, placing passengers at risk of a severe rear-end collision. Furthermore, the complete loss of climate module communication controls the battery pack's thermal management/chiller plate; an unmonitored thermal loop on a lithium-ion hybrid battery is a distinct fire hazard. This is a documented, recurring issue affecting the BMW X5 xdrive50e platform, and a federal safety investigation/recall is required before an owner suffers an accident or thermal fire.

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I drive a 2015 BMW X5. While driving on a local street, I heard a severe banging noise underneath the car. I pulled over, and it turned out the front driveshaft had broken, striking the transmission pan and other parts beneath. When I towed the car to the shop the mechanic also found that an ac drain line dripped onto the driveshaft u-joint, causing rust over time, which led to this failure. There were no warning lights prior. If this had happened on the highway, it could have caused far greater damage--potentially to the transmission, transfer case, front differential, or even the engine. This was a serious safety risk, and I urge the NHTSA to investigate this design flaw and consider a recall on affected models before others suffer similar damage.

I own a 2022 BMW X5 xdrive45e that has developed a drivetrain shudder during slow-speed, tight turns while lightly accelerating, such as when maneuvering in parking lots or making u-turns. The vibration is consistently reproducible under these conditions and is felt through the vehicle during the turn. The vehicle otherwise drives normally at higher speeds. After researching the issue, I found that many other owners have reported substantially similar symptoms involving the transfer case on BMW xdrive vehicles. My independent BMW repair shop has recommended a transfer case fluid service as the first corrective action based on the known nature of this problem. I am having that service performed and will retain all repair documentation. I am submitting this complaint because this appears to be a recurring issue affecting multiple vehicles. If the condition worsens, it could lead to drivetrain binding during low-speed maneuvers and may affect safe vehicle operation. I request that NHTSA investigate whether this is a broader defect requiring manufacturer action. I will update this complaint if the repair does not resolve the condition or if additional diagnosis identifies an internal transfer case failure.

Front differential input bearing failure. Sudden jerking that almost causes loss of control. This poses a safety risk. This seems to be a know problem for the 2020 BMW X5 m50i no warning lights and I did not experience hearing any sounds as other have reported.

2021 BMW X5 xdrive45e phev, built October 2020 by BMW ag (germany). In-service oct 28, 2021. Vehicle intermittently shows "drivetrain malfunction — you can continue driving" warning. Dme scan reveals 5 fault codes, all for the conventional 12v pinion starter: 21a50a — pinion starter: timeout occurred several times in succession 21a511 — pinion starter: timeout 21611a — pinion starter: starting torque could not be built up; high counter torque and/or undervoltage 216119 — pinion starter: line break in starter control (kl50/kl30) 216115 — pinion starter: attempt to start with blocked starter detected 21a50a and 216115 are protected memory codes that cannot be cleared by standard obd-ii tools. The main 12v agm battery was replaced and registered; codes continue to recur. This signature matches the b58 pinion starter defect addressed in NHTSA recall 24v-576 (Aug 2024) and 25v644 (Nov 2025, physical starter replacement). The vehicle's german manufacture date falls inside the production windows of kba recalls 15630r, 15632r, and 15633r — all covering X5 g05 for short-circuit and fire risk from starter relay corrosion or inadequate mounting. BMW ag has issued an adac advisory not to leave affected vehicles running unattended after starting. BMW na customer relations was contacted. Initial verbal response: u. S. Recalls don't apply because the xdrive45e phev uses a different starter than non-hybrid b58 vehicles. However, codes 216115 and 216119 only exist on vehicles equipped with a conventional pinion starter — confirming this vehicle has the same component. The subsequent written denial pivoted to warranty expiration without addressing the technical or recall-scope questions. Filing so the field record reflects this defect signature for future u. S. Recall scope expansion analysis.

Noticed noise. Took to dealer. Dealer confirmed bad front pinion/bearing and need front differential. Will be very dangerous if not fixed! dealer has had this issue before and online forums state big issues.

The vehicle’s rear differential has developed significant internal "play" (excessive clearance between gears). This defect manifests as abnormal vibration and inconsistent power delivery to the wheels. The vehicle was inspected by an authorized BMW technician at passport BMW . Although I reported hitting a curb (low-speed impact), the official diagnostic report from the BMW technician explicitly stated that the curb impact did not cause the differential failure. The technician identified the issue as a failure of the internal differential components, which is consistent with numerous reports of drivetrain defects in the b mw X5. Despite the vehicle being well under the 50,000-mile warranty threshold and the technician’s own finding that external damage was not the cause, BMW is currently refusing to honor the warranty repair for this critical mechanical component. I purchased the vehicle in March 2025 certified pre owned.

Front differential - repair/replacement on 2021 BMW X5 m50i. Extreme safety issue. Ironically failed right after 50k warranty. Currently at 50742 miles. Brought vehicle in 6 different occasions in the last year and a half. One time for a similar issue (approx. 1 year ago) and instead of addressing the problem at the time they just replaced the transfer case, masking the root issue and pending complete failure of the system.

My daughter was driving my BMW X5, it went to neutral and not moving, she was panicked and stopped the car and ignition. After restarting the car, it worked for a day, then it happened again, also, I see notifications on dashboard for restraint warning, saying, airbag, and seat belt tension are reduced. I took to fairfax BMW in va, BMW quoted $2662, informed that my BMW went out of extended warranty over a month, I asked goodwill request to BMW, still declined.

Component / fault category: electrical system / power train / blind spot warning summary of the defect: on April 11, 2026, my 2019 BMW X5 suffered a sudden electronic system shutdown at highway speeds near the 210 exit, stranding the car on the roadway and requiring aaa towing. BMW of ontario falsely blamed "liquid damage" in the gsw shifter and texted an inflated quote of $6,616. 05, later reduced to $3,616. 05 on invoice #bfcs684959 before waiving fees for oil changing and so on due to communication errors. No liquid spill occurred. The gsw module near cup holders suffers from an unsealed design defect where ambient condensation causes total drive power loss. Detailed incident narrative: the center console in the BMW X5 (g05) lacks basic liquid/moisture isolation. Condensation or ambient humidity short-circuits critical shifting electronics, causing immediate loss of drive power on public roadways and creating an extreme crash risk. This incident is part of a clear pattern of systemic electrical vulnerabilities on this specific vehicle: 1. Starter safety recall & highway shutdown: last year, this vehicle suffered a sudden highway shutdown caused by a faulty starter. BMW failed to send a recall notice beforehand. After I was forced to pay out-of-pocket for emergency repairs at coast BMW, BMW later recognized the recall and issued a full reimbursement this year. 2. Blind spot warning system failure: the vehicle also suffered an unexplained, premature failure of the blind spot warning system (quoted at over $3,000 to repair and left unaddressed), proving broader electronic/sensor vulnerabilities. Furthermore, dealership handling involved deceptive, erratic quotes ($6,616. 05 texted initially vs. $3,616. 05 on the invoice) to shift financial liability for a latent design defect onto the consumer.

Failure of front differential.

The contact owns a 2020 BMW X5. The contact stated that the vehicle was taken to a dealer for routine maintenance and it was discovered that there was a coolant leak and that there was a failure with the front differential failure, and that the a/c unit was leaking. The leaking valve was replaced but the differential was not repaired. The contact stated that the failure was a known failure with the vehicle. The manufacturer was made aware of the failure. The failure mileage was 70,000.

Xdrive all-wheel-drive has made the car slow down unexpectedly and produce a shudder, especially in slow corners and under gentle acceleration. The vehicle has also rapidly accelerated upon entering or exiting a freeway on ramp.

Drivetrain malfunction reoccurring 2x in 45 days. First error message the dealer charged me $600 to fix. Bringing car in second time now. Unsafe to drive due to power cutoff. This is a phev. Car is under the original mfr warranty and less than 3 years old.

2016 BMW X5 xdrive40e. Experiencing intermittent/sudden drivetrain malfunction warnings. Vehicle loses power or enters limp mode while driving. Max edrive / electric drive becomes disabled even with battery charged. Multiple warning lights appear. Issue appears related to the hybrid system (possible eme, sme, safety box, or high-voltage battery faults). This creates a safety risk because power can be lost unexpectedly while moving. Mileage at time of most recent occurrence: 126,500. Problem first noticed 118,000.

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 went to drive the car and there was a drivetrain malfunction error. The car could not be driven and had to be towed.
