2020 BMW M340i

My oil pump went out causing Low pressure codes and resulting in me paying over 2 grand to get it repaired, They super seeded the oil pump they used to use with a new one and theirs many other reports online etc of the 2020 bmw m340 oil pump going out due to plastic internals which can lead to engine failure .

Oil pump common issue of made out plastic cause miss interpretation of oil pressure. Developing engine issues under 50k miles

Hi. I’d like to point out I have not had an incident YET thankfully. However, I want to highlight that the early M340i production releases (2019 and 2020) are HIGHLY likely to experience catastrophic engine failure due to an oil pump being made of plastic on some models. Of the 20 or so complaints listed under this vehicle on NHTSA, I’ve already seen PLENTY of complaints regarding this issue and people actually experiencing this issue. I believe if a car has a fair chance of causing catastrophic damage to its engine on its own, it poses as a safety risk for anyone in or around the car. The fix is to spend $6000-$7000 to have the oil pump replaced with the new 2021 oil pump, but most normal people cannot afford that easily and are driving around with plastic pumps still hoping for the best. I don’t understand how so many complaints of the same safety issue on this website for this vehicle (and other vehicles, which have the same B58 engine) have not resulted in a recall. Hopefully this can change because a car destroying itself shouldn’t be taken lightly and I’d like to second what everyone else on here is saying about the oil pump issue.

Electronic parking brake malfunction, disengage ineffective. Ongoing 2020 BMW mechanical issue, multiple dealer submissions, BMW refuses to open active recall. BMW requires $3,000 center panel replacement, out-of-pocket.

The contact owns a 2020 BMW M340I. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 24V576000 (Electrical System, Engine and Engine Cooling); however, the repair failed to prevent the failure from occurring. The contact stated that shortly after the recall repair was completed, the vehicle hesitated to start. The contact stated that several employees at the local dealer attempted to start the vehicle. The vehicle started; however, several months later, the failure reoccurred. An appointment with the dealer was scheduled to inspect the vehicle. The vehicle was not repaired and needed to be towed. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 28,162.

My vehicle doesn’t read the oil level since the fuel pump that BMW used to manufacture the car is made out of plastic material. There has been hundred of complaints about the same issue with the oil pump not working properly due to the fact that BMW used plastic instead of metal etc. I would like for the NHTSA to take a look at this issue and please consider making it a recall for the users that are having this “Oil Pump” issue please thank you.

I cruised on a city street at the speed limit. The light turned red and I came to a full stop. The start/stop system was activated and the engine “stopped” to conserve power while my foot was on the brake. The light turned green and I took my foot off the brake, the engine failed to start and did not start with countless attempts. Digital cluster and CarPlay proceeded to work, exterior lights work. Called a tow to the nearest BMW dealership for assistance.

Car will not measure oil past 20%. Seems like lots of 2020 models have a faulty production oil pump. Car is now out of warranty and dealer charged $5000 to fix the issue but do not know 100% if oil pump replacement will fix it. BMW changed the oil pump in the later models but did not mention anything about any recalls or replacements. Unacceptable.
