2020 BMW M340I recalls
Starter Can Overheat and Ignite a Fire Under Repeated Start Attempts
If the starter motor fails, repeated attempts to start the vehicle can cause the starter to overheat from an electrical overload.
Seat Belt Chime May Fail to Warn Driver to Buckle Up
A software fault in the receiver audio module can prevent the audible seat belt warning from sounding properly to remind the driver to fasten their seat belt.
Seat Frame May Not Hold Occupant in a Crash
Some BMW vehicles may have seat frames that were not welded properly to the seat rails.
Engine Software May Cause Loss of Braking Assist at Startup
The engine management software in certain vehicles may cause a loss of braking assist during engine start.
Rearview camera may be blocked or go dark in reverse
When the vehicle is shifted into Reverse, part of the rearview camera image can be obscured, or the screen may not turn on.
Steering Tie Rod May Fracture, Risking Loss of Control
A steering gear tie rod in these vehicles can become damaged when driven in certain conditions, such as high temperatures and rough road surfaces.
Seat belt sensors may misread belted occupants in crashes
Sensors in the front seat belt buckles may incorrectly detect a belted driver or front passenger as unbelted.
Trunk May Not Open From Inside, Risking Trapped Occupants
The interior trunk release cable may have been improperly installed, which can keep the trunk from opening from the inside.
Rear-view camera image can be turned off, raising crash risk
The rear-view camera display on these vehicles can be adjusted so the backup camera image no longer appears, and the system keeps that setting the next time the car is put in reverse.
Rear Headrest May Fold Down in a Crash, Raising Injury Risk
Due to improper welding, the rear center headrest in certain 2020 M340i vehicles may fold down in a rear impact crash.

What owners report
Oil pump Issue, oil starvation to engine making it unreliable
I am reporting a safety concern involving BMW vehicles equipped with the B58 Technical Update (B58TU) engine, commonly found in model years 2019â2021. 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 wa
I'm 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 d
Plastic components in the oil pump went out. BMW has made new oil pumps with metal components that are less fragile and do not fail as often. Outside of warranty these repairs can be very costly. I have had to pay out of pocket for these repairs myself. I do not understand why this is not a recall.
