2021 BMW M340I recalls

I have been smelling a burning odor in the vehicle for almost a year which the dealership and an independent shop had not been able to diagnose. The car was recently throwing Drivetrain Error codes which prompted a visit to the dealership. They found that the 48v battery and negative cable are burnt and quoted $5680 to replace the battery and cables. After investigating I found that there were recalls for this issue on other BMWs, including the same year and model of my vehicle, but my VIN is not pulling up a recall. The issue is a fire risk and a very expensive repair that should be covered by the manufacturer due to a known defect.

The BMW B58TU oil pump thermoplastic component issue that can cause catastrophic failure to the engine. The the gen 1 oil pump was made from plastic and after issues were discovered, they switched to metal oil pumps. However this known issue is something that BMW has not addressed in the models 2019-2021 that came with the inferior oil pump.

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 warn

Here’s a strong version that sounds frustrated but still credible and harder to dismiss: I’ve owned many vehicles over the years, and this BMW has been, without question, the most problematic car I’ve ever had. The list of issues has been absurd for a vehicle in this price range and from a brand that markets itself as a premium luxury manufacturer. The sunroof failed, I’ve had multiple tire blowouts under normal driving conditions, the drive bar/suspension was bent from what should have been a routine road bump, the engine oil housing/component failed, and now I’m dealing with coolant system and drivetrain problems as well. At this point, it feels like one major issue after another. I expect

I am reporting a safety concern with BMW vehicles equipped with the B58 Technical Update (B58TU) engine, primarily in 2019–2021 model years. These vehicles use a variable-displacement oil pump containing an internal thermoplastic adjusting component that regulates oil pressure. This plastic part is prone to fracturing, leading to sudden loss or instability of engine oil pressure. Failures most commonly occur during cold starts in low ambient temperatures. When the component breaks, oil pressure regulation fails with little or no warning. Drivers often experience precursor symptoms such as inability to electronically read oil level, erratic oil pressure, or sudden drivetrain warnings. The iss
