What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2018 BMW M240I, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
The daytime running lights (DRL) LED module overheated due to poor thermal design burning the connection point and turning the"angel eyes" amber, yellow.When the LED module overheats, it chars and browns the leading edge of the internal fiber optic light tube which permanently alters the refracted light color from crisp white to amber/brown.BMW has released a Technical Service Bulletin acknowledging this dimming/discolorization "flaw". BMW reuses to cover this out of warranty because they claim a Technical Service Bulletin is not a recall ergo a safety issue.BMW claims this is a cosmetic or minor component failure, not a safety issue.This LED module eventually burns out completely and the DRL will go dark.This reduces the vehicle's visibility to oncoming traffic during the day creating a safety hazard.My contention is that this warrants a vehicle recall since DRL are mandated in all vehicles to improve a vehicle 's visibility. Thank you
Each of the two LED taillights have failed. The right rear LED turn signal failed in the Spring of 2022 when the car had approximately 12,000 miles of use and the left rear LED turn signal failed in the Fall of 2023 when the car had approximately 15,000 miles of use.

2018 BMW M240i - no sound from radio, or any aux input. May be blown amplifier. Extremely loud crackling sound, intermitent sound.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
