2019 BMW X7 engine problems

ENGINE

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/lubrication. 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. 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, demonstrating knowledge of the defective component.

I was told today that my BMW engine oil pump is failing because of plastic internal components which will cause irreversible catastrophic engine damage during operation which is extremely dangerous and that I was informed by the dealer that BMW quietly changed them 2 years after due to the failure rate. If the oil pump shatters, debris can permanently damage the engine during operation jeopardizing my safety and those driving around me, making replacement with the upgraded, all-metal oil pump, that BMW quietly changed due to this failure, nearly $6k -$8k to fix and is not covered though they admit it is a known failure/safety issue. As of XXX, BMW Korea is running a free repair campaign (recall) to address oil pump failures affecting the B58TU engine in that country. Affected vehicles include models manufactured between XXX and XXX. BMW Korea replaces the non-safe original plastic oil pump with BMW's upgraded metal design, and even covers prior out-of-pocket replacements. NHTSA needs to hold BMW accountable and force BMW USA to complete the same safety recall for the exact same issue of faulty engine oil pumps they installed to save money as BMW Korea for the United States. Safety recalls should NOT be optional in USA and especially so if BMW is already doing the recall in another country for same issue identified in their cars sold here in the [XXX] too.

ENGINE

My 2019 BMW X7 is under Safety Recall 25V-644 for an overheating/fire-risk defect, but the recall remedy is unavailable. The vehicle has now experienced multiple safety-related failures that appear to be progressing. BMW diagnosed the following failures: • Emergency Call System Malfunction • GPS and maps not working • Failure of the TCB telematics module • Failure of the antenna and TCB battery due to fluid ingress • Battery voltage in the red zone • All four tire pressure sensors beginning to fail • Collapsed engine mounts attributed to heat • $11,296 in repair estimates related to electrical and heat damage Immediately after picking up the vehicle from BMW service, a new battery/charging system warning light appeared that was NOT present before the visit. This suggests further deterioration of the electrical system. The combination of: • an open fire-risk recall with no fix available, • fluid ingress damaging telematics components, • multiple electrical and safety-system failures, and • new warning lights appearing after service makes this vehicle unsafe to operate, especially for long-distance highway travel. I am requesting that NHTSA document this as a safety-defect case and assist in ensuring BMW provides a safe resolution.

When trying to start the vehicle it will say that the starter has overheated and to try restarting again in xx seconds. This occurs randomly and the car does not indicate that the engine is over heating, just the starter. When looking online it appears there is an active recall for this very issue but my VIN is not registered with the recall. BMW believes that my car should be covered under this warranty and advised filing a report with the NHTSA to have it extended to my car. The vehicle is a 2019 and was produced in March of 2019.
