1 Engine And Engine Cooling problem of the 2021 BMW X5

Failure Date: 06/25/2026

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.

2 Engine And Engine Cooling problem of the 2014 BMW X5

Failure Date: 06/19/2026

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).

4 Engine And Engine Cooling problem of the 2022 BMW X5

Failure Date: 06/06/2026

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.

5 Engine And Engine Cooling problem of the 2019 BMW X5

Failure Date: 05/30/2026

I am writing regarding my BMW X5 xdrive40i, model year 2019, engine code b58tu. The vehicle has been serviced at authorized BMW dealerships. For this engine type b58tu especially years 2018-2021, repeated oil pump failures have been reported due to a known design issue: an internal plastic component can develop cracks, potentially leading to a complete oil pump failure. BMW silently replaced the oil pump with the updated version by keeping the same part number but featuring metal internals. Once there is a fail on the oil pumps with plastic components, engine loses access to get the oil an immediate stop is needed. This creates a huge safety concern cause: 1) if you are on a highway at highway speeds it might not be possible to move to the shoulder safely with no engine power or even worse: with a locked engine. 2) if there is a maintenance on the road with no shoulder access or if this is a bridge where there is no shoulder, it creates a huge risk to safely move the vehicle. An unavoidable sudden stop can create a huge accident risk for everybody. Of course any car can get a engine problem on those occasions but this is a very known and very common problem for BMW cars equipped with b58tu engine especially years 2018-2021. BMW is also definitely aware of that and this safety concern cause they updated the design silently. But, when contacted with BMW na, they refused to help, refused to admit there is a design problem. They also refused to change the oil pump with the updated oil pump even with my proposal of goodwill pricing.

6 Engine And Engine Cooling problem of the 2019 BMW X5

Failure Date: 05/18/2026

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. Owners are currently unable to determine whether their vehicles contain the original thermoplastic oil pump design or a later revised version utilizing metal internal components, as VIN-based parts information now identifies updated components in the car even when no replacement has occurred and the old components are actually in the car. Also, BMW has actively removed the plastic part number out of all dealer networks as well.

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.

8 Engine And Engine Cooling problem of the 2021 BMW X5

Failure Date: 05/06/2026

After the car was. Parked in sun for aome time during shopping at costco, it did not start. We had to use remote starter which worked. However, upon doing some research I found that overheated starter is a known and recalled problem with 2021 X5 and remote start could have caused fire. Dealership also confirmed it to be the smae pronlem , but BMW has not listed this VIN as recalled. I contacted BMW and they denied that it was same. Problem, although mine is also 2021 X5 with smae. Overheated starter problem.

9 Engine And Engine Cooling problem of the 2021 BMW X5

Failure Date: 05/01/2026

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.

10 Engine And Engine Cooling problem of the 2012 BMW X5

Failure Date: 04/28/2026

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.

12 Engine And Engine Cooling problem of the 2019 BMW X5

Failure Date: 04/10/2026

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).

13 Engine And Engine Cooling problem of the 2021 BMW X5

Failure Date: 04/09/2026

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?????.

14 Engine And Engine Cooling problem of the 2021 BMW X5

Failure Date: 03/31/2026

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.

15 Engine And Engine Cooling problem of the 2020 BMW X5

Failure Date: 03/29/2026

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.

17 Engine And Engine Cooling problem of the 2018 BMW X5

Failure Date: 03/09/2026

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.

18 Engine And Engine Cooling problem of the 2011 BMW X5

Failure Date: 02/28/2026

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!.

19 Engine And Engine Cooling problem of the 2019 BMW X5

Failure Date: 02/28/2026

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.

22 Engine And Engine Cooling problem of the 2022 BMW X5

Failure Date: 02/19/2026

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.

23 Engine And Engine Cooling problem of the 2020 BMW X5

Failure Date: 02/15/2026

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.

24 Engine And Engine Cooling problem of the 2020 BMW X5

Failure Date: 02/12/2026

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.

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.

25 Engine And Engine Cooling problem of the 2020 BMW X5

Failure Date: 02/08/2026

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.

26 Engine And Engine Cooling problem of the 2022 BMW X5

Failure Date: 02/03/2026

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.

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.

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.
