BMW 840i Recalls

The BMW 840i has 8 recalls covering 2019 through 2025 model years, with the most serious being a starter motor that can overheat from electrical overload on 2020-2025 vehicles, igniting nearby materials in the engine compartment and causing an engine fire.

The 2020 model year carries additional fire risk from a separate path: a 12-volt battery connection issue on 2021 models can increase electrical resistance and also raise the risk of an engine fire. On 2020-2021 vehicles, the hydraulic brake booster system can fail, causing a loss of anti-lock braking function and reduced braking assistance, which extends stopping distances. The 2020 model year also has a seatbelt pretensioner defect where the pretensioners and airbags can deploy improperly in a crash, raising the risk of injury to the driver and front passenger.

Two rearview camera recalls affect earlier production. On 2019-2021 models, a software issue can cause the backup camera image to disappear or show a reduced view while reversing. The 2019 model year has a related hardware issue where the camera itself can fail to display any image when backing up. Both conditions remove the driver's rear visibility and raise the risk of a collision while reversing.

The 2023 model year has a lower-severity software recall where the windows and sunroof can close on their own without the key present, which can trap an occupant inside the vehicle.
