2019 BMW X5

Around June 10th, I was on vacation when I noticed my AC was not very cold in this vehicle, which I had purchased used about a month earlier. I took it to get recharged while on my vacation, and it blew nice and cold until a few days ago. After doing a little digging, it appears that the 2019 and 2020 model year of the BMW X5 G05 have an evaporator core made of aluminum, and the refrigerant used (R1234yf) is known to be corrosive to aluminum, causing leaks in the core. While this is widely talked about in online forums amongst those who have experienced this issue, it appears no safety recalls have been made about this issue. The problems, as I see it, are two fold: 1> Without a working AC system, the vehicle cannot safely defrost the windows when conditions are favorable for frost or fogginess. 2> The health hazards of inhaling leaked refrigerant, along with it's by-products (like trifluoroacetic acid) do not need to be explained. Refrigerants are known to be dangerous both to human health as well as to the environment, so this is not an acceptable environment to be exposed to. While I have not had an accident caused by this, I believe preventative steps should be taken to prevent them from occuring, given this is a fairly common problem with the 2019/2020 model year of this vehicle.

The oil pump failed on my X5. The factory installed oil pump has a plastic housing that cracks and leads to oil pump failure. BMW replaced the part with a newer model that has a metal housing.

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

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

The vehicle is at A&L Motors in Monroeville Pa. The vehicle has suffered a catastrophic, cascading electrical failure caused by a known manufacturing defect in the roof antenna seal. Rainwater entered the vehicle through the defective shark fin antenna seal and flooded the Telematics Control Unit(TCU). Because the TCU communicates directly with the main iDrive head unit via the vehicle's MOST/bus central data network, the water-damaged TCU short-circuited and flooded the network with corrupt electrical data, hard-bricking the iDrive system. A dealership engineer confirmed that water did not physically touch the head unit, eliminating user-error fluid spills. This cascading electrical failure has completely disabled vital safety systems, including the backup camera, forward collision driver-assist radar warnings, blind-spot monitoring alerts, and critical dashboard diagnostic notifications, creating an immediate highway safety hazard. Simultaneously, the active grille shutters (active air flaps) failed due to a defective internal actuator motor, creating a severe risk of sudden engine overheating and thermal shutdown. This component is under a 150K mile manufacturer warranty extension(SIB01 12 19 and later sib01 03 25). BMW of North America Claims Manager Joe 1-800-831-1117Ext1427 has issued an arbitrary final denial for these repairs based on a hearsay rock wedged/strike despite no apparent physical damage and zero photographic evidence. BMW is actively evading its extended warranty obligations for the air dam and a pending class-action settlement framework (Craft v. BMW NA) on the IDrive components. Additionally, this vehicle is actively subject to the critical BMW Starter Motor Overheating Fire Risk Recall NHTSA Campaign No.25V644/26V056. The dealership is unable to complete this urgent fire-safety remedy due to the same bricked Idrive unit.

Oil pump with plastic parts failing

Incident

The engine oil pump failed internally. The vehicle is equipped with a factory-installed variable-displacement oil pump that utilizes an internal thermoplastic adjusting ring. Due to heat cycles and mechanical stress, this plastic component degrades, becomes brittle, and catastrophically shatters or cracks.The first symptom appeared when the vehicle became entirely unable to complete an electronic engine oil level measurement via the iDrive system, consistently freezing and aborting the test at approximately 15% to 20%. This defect directly compromises road safety. A sudden drop in oil pressure causes severe internal engine friction, leading to immediate engine seizure or a total loss of motive power without adequate warning. Experiencing a sudden engine stall while driving at highway speeds places the driver, passengers, and surrounding motorists at extreme risk of a high-speed rear-end collision. Furthermore, a total engine shutdown disables power-assist steering and braking, making the vehicle incredibly difficult to control and maneuver to safety. Catastrophic mechanical failure from oil starvation also presents a severe under-hood fire hazard if oil leaks onto hot exhaust components.The problem has been officially reproduced and confirmed. The vehicle was brought to Bavarian Werkstatte, where certified technicians diagnosed the issue as an internal structural failure of the variable-displacement oil pump's plastic adjusting ring. The component is currently available for inspection upon request. BMW is fully aware of this defective design. They updated this exact component in mid-2020 to an all-metal oil pump to prevent plastic fragmentation. Despite knowing that the 2019 thermoplastic rings degrade, become brittle, and shatter under normal operating heat cycles, the manufacturer has failed to issue a safety recall in the United States, leaving drivers exposed to dangerous sudden engine failure.
