   I am reporting a chronic manufacturing defect on my 2020 BMW X3 that poses an immediate electrical short-circuit and vehicle safety hazard. The passenger-side panoramic sunroof drainage system/roof structure leaks water heavily through the side panel joint of the door frame, directly saturating the front passenger floor carpet. This issue has been ongoing since I received the vehicle in 2020.The vehicle has been brought to Kelly BMW of Columbus, Ohio, at least four separate times since 2020 specifically to address this leak. Technicians have replaced outer seals and cleared tracks, but the leak persists, and on the last visit, unqualified dealership staff claimed they "could not find anything wrong. "This is a severe safety risk: BMW places the primary electronic fuse blocks and vital vehicle wiring harnesses directly underneath the front passenger floorboard carpet. Constant water logging in this exact area threatens to cause sudden, catastrophic electrical failures, component shorts, or vehicle stalling while driving. The manufacturer has failed to issue a recall for this known, widespread G01 platform defect, and dealership service centers lack the training to properly diagnose it.

   The contact owns a 2020 BMW X3. The contact stated that while driving 25 MPH, the message “Heat Management Module Malfunction” was displayed and the warning light was illuminated. The drive-train warning light was illuminated. Upon research, the contact became aware of NHTSA Campaign Number: 21V586000 (Fuel System, Diesel). The vehicle was previously taken to the dealer to be diagnosed, and the contact was informed that the high-pressure fuel pump needed to be replaced. The vehicle was repaired, but the failure reoccurred. The manufacturer was contacted, but no additional assistance was provided due to a prior good-faith repair being provided. The failure mileage was approximately 70,000.

   Heat Management Module HMM is bad. BMW used a plastic part that is right up against the engine block. This HMM Heat Management Module resulted in STOPPING the vehicle completely in the middle of the freeway. I had no control. Then the car drove, then stopped again. I had NO CONTROL over the vehicle. Weeks later the Drivetrain Malfunction warning light appeared as i was driving home late at night from the ER. I took it to my BMW dealer. The diagnostic test was performed and was told the Heat Management Module HMM needed to be replaced at a cost to me of $3000. I contacted BMW USA, explained what transpired and they responded with a denial. I stopped driving the car completely after i found other complaints about BMW using an inferior part on the 3 series and the same issue about the car stopping in highway traffic without any control. I later got my BMW repaired, at the BMW dealer, as i could not afford to buy another car. I have the defective inferior part in my possession for inspection by NHTSA. BMW refuses to recall the Heat Management Module HMM and will not address the Drivetrain Malfunction warning light. I would like this to be escalated and investigated by NHTSA.gov so that others may be safe when driving please. Thank you.

   I own a 2020 BMW X3 M40i, VIN [XXX], manufactured November 2019, now at approximately 100,000 miles, equipped with the B58TU engine. My oil level sensor stopped completing measurements at approximately 45,000 miles, a known precursor to thermoplastic oil pump failure. For 55,000 miles I had no way to identify whether my vehicle contained the defective component because BMW removed the original thermoplastic part number from all dealer networks. VIN-based lookup now falsely returns updated metal component information regardless of what is physically present in the vehicle. This makes proactive identification impossible for both owners and dealers, meaning the defect cannot be remediated even by willing owners. I had no actionable path forward. On [XXX] I was driving on a Florida highway at 80 mph when a low oil pressure warning appeared. I pulled over immediately. A fault log pulled at 2:05PM showed code 1C3002. A second log pulled at 6:49PM after briefly running the engine showed three additional oil system faults including 1C2002 - engine oil pump pressure too low - indicating active progressive failure within hours. This failure occurred in 90 degree Florida summer heat, not cold weather. If NHTSA’s investigation is scoped around cold climate failures, my case demonstrates that scope is incomplete and the affected population is broader than currently documented. Carfax records confirm 18 total service records over 100,000+ miles, including 8 dealer visits between 18,000 and 50,000 miles under active CPO warranty. This vehicle has been consistently and properly maintained throughout its life. The vehicle became a safety hazard at highway speed without adequate warning. I will file a second complaint after physical inspection confirming which pump variant is actually present. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

   reporting a safety issue with BMW vehicles equipped with the B58TU engine, primarily 2019-2021 models. These vehicles have an oil pump with an internal plastic component that regulates oil pressure, and this part is fracturing in the field, causing sudden loss of oil pressure. The failure typically occurs during cold starts in low temperatures. When it 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, or sudden drivetrain malfunction warnings. These can rapidly progress to engine shutdown or severe damage from oil starvation. This creates a dangerous situation because the vehicle can become disabled without warning while driving or after startup. This is especially hazardous when cars become immobilized in traffic or during winter conditions when failures occur most frequently, leaving occupants exposed to freezing temperatures while awaiting assistance. Pump replacement requires extensive disassembly and commonly costs $6,000-$8,000, assuming no engine damage. A critical concern: owners cannot determine if their vehicle has the original plastic pump or the later metal revision. BMW's VIN-based parts lookup now shows updated components even when original plastic parts remain installed, and BMW has removed the original plastic part number from dealer networks entirely. Failures are reported across multiple production years, and the scope of affected vehicles remains unclear. Because this condition causes sudden vehicle disablement without adequate warning, especially in cold weather, I believe this warrants investigation as a potential safety-related defect.

   I am submitting this complaint regarding ongoing and potentially dangerous mechanical failures involving my vehicle that have repeatedly occurred despite numerous repair attempts by the dealership. Over the past year, I have taken my vehicle to the dealership more than 10 times for serious recurring issues. The problems have included: Drivetrain malfunction warnings Engine warning lights Oil leaks Smoke coming from the vehicle The vehicle unexpectedly shifting into neutral while driving Sudden loss of drivability requiring the vehicle to be towed The dealership has repeatedly stated that the issues were repaired, and at one point even provided a one-year warranty on the repair work. Despite this, the same problems have continued to occur. Most recently, the drivetrain malfunction warning and engine light returned again, smoke came from the vehicle, and the car shifted into neutral on its own, becoming completely undriveable and requiring towing. I have spent more than $10,000 on repairs related to these ongoing issues, yet the vehicle remains unreliable and unsafe. My primary concern is the safety risk posed by the drivetrain failure and the vehicle unexpectedly shifting into neutral while in operation. I am requesting that this matter be reviewed as a potential vehicle safety issue. I believe these repeated failures may present a serious risk not only to myself but potentially to other drivers as well. Thank you for your attention to this matter.

    It has come to my attention that liquid from the Positive Crankcase Ventilation (PCV) system may leak onto the water pump electrical connector. This condition can lead to an electrical short circuit and, in rare cases, may increase the risk of a vehicle fire. This issue presents a serious safety concern for vehicle owners and others on the road. A failure of this nature, especially one that carries a fire risk, warrants immediate review and corrective action. I respectfully request that NHTSA investigate this matter and determine whether a safety recall is necessary to address this defect. The dealership noticed the leak beginning at the weep hole of the waterpump. No incident occurred this is for preventive measures and review for recall and reimbursement

    I am submitting a formal safety complaint regarding a defect in my 2020 BMW X3 that has resulted in the failure of a critical emergency safety system. The vehicle displayed an error message indicating an “Emergency Call System Malfunction.” I brought the vehicle to BMW of Murrieta on March 30, 2026, for diagnosis and repair. Upon inspection, the service center determined that the Telematic Control Unit (TCU) had sustained water damage. This damage was attributed to water intrusion originating from the vehicle’s shark fin antenna. This is a known issue documented by BMW in internal Service Information Bulletin SIB 65 12 22 (dated October 5, 2022). Despite acknowledgment of this known defect, BMW declined to cover the repair costs for both the antenna-related water intrusion and the resulting damage to the TCU. This failure presents a significant safety hazard. The emergency call system is designed to automatically notify emergency services in the event of a collision. With this system inoperable, occupants may be unable to receive timely emergency assistance, increasing the risk of serious injury or death. Given that BMW is aware of this defect and its potential to disable a critical safety feature, I believe this issue warrants further investigation and should be considered for a mandatory safety recall.

    This recall was in September 2025, and for a starter issue that could cause a fire. Despite the urgency of this recall, it's now six months later, and I am still getting a response from BMW "Remedy Not available". So, in the meantime BMW advises to keep the car outside in the hot Florida sun so it doesn't burn the house down. This is a totally unacceptable situation, and I would appreciate the NHTSA following up with BMW regarding why the delay. It appears to me that BMW is dragging their feet on correcting this serious issue.

    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. They are aware.
