14 recalls across 5 model years
The BMW M340i has 14 recalls covering 2019 through 2023 model years, with the most serious being a steering tie rod defect on 2019-2020 vehicles where the rod can fracture under high heat or rough road conditions, causing a sudden loss of steering control.
The 2023 model year has a body control module software fault where the doors may not lock while the vehicle is moving and can swing open in a crash. On 2021 models, a loose seat belt assembly bolt means the belt may not hold an occupant in a crash, and a separate seat belt retractor issue on 2021 vehicles can prevent the belt from functioning correctly during a collision. There is also a 12-volt battery connection issue on 2021 M340i xDrive models where increased electrical resistance can generate enough heat to start a fire.
The 2020 model year carries several safety-related issues. Engine management software can cause the brake booster to stop assisting during engine start, leaving the driver with full but unassisted braking effort. Seat belt pretensioners and airbags on 2020 vehicles may deploy incorrectly in a crash, reducing occupant protection. A rear center headrest on certain 2020 M340i and M340i xDrive vehicles can fold down in a rear impact rather than supporting the occupant's head. The starter motor on 2020 models can overheat and ignite nearby material in the engine compartment. The interior trunk release cable on 2020 330i and M340i vehicles may be improperly routed, preventing someone inside the trunk from opening it.
Spanning 2019 through 2021, the seat frame on certain vehicles may not be properly welded to the seat rails, which can allow the seat to shift in a crash and fail to restrain the occupant. Rearview camera software on 2019-2021 models can produce a missing or reduced image while reversing, and a separate camera hardware issue on 2019-2020 vehicles can cause the backup display to go blank entirely. Going back to 2019-2022 production, the audio module software may fail to sound the seat belt reminder chime, removing the audible prompt for the driver to buckle up.
