Owner report 11667474 · 2025-06-17 (June 17, 2025)

The car basically blew up on the highway at rush hour. BMW knows of this issue with this model and has some of their other models under a recall for this very thing. I have a service action from BMW saying that the water pump assembly needs to be fixed before this very problem occurs but for some reason even though our model is on the service report it isn't on the recall list nor was this part replaced as instructed even though the vehicle has always been service at a BMW dealership. It was very dangerous as their were flames and burning ho…

Owner report 11753304 · 2026-07-28 (July 28, 2026)

I am seeing a lot of concerns regarding the seatbelt extenders, the buckle end pretensioner, seat wiring harness and the yellow box connectors that are where the main power and air bag SRS connections sit under the drivers seat. The seat harnesses are catching in the sliding track mechanism during forward and backward adjustments, isn't that a manufacturer error as the harnesses are only kept in place by plastic routing clips, which may or may not be there. I am just wondering if this should be looked at on the 2021 440i convertibles? I love…

20V761000 · Electrical System:12v/24v/48v Battery

Reported: 2020-12-09 (December 9, 2020)

BMW of North America, LLC (BMW) is recalling certain 2021 M340i xDrive, M440i xDrive Coupe, 530i, 530i xDrive, 540i, 540i xDrive, 740Li, 740Li xDrive, 840i Gran Coupe, 840i xDrive Gran Coupe, X5 sDrive40i, X5 xDrive40i, X6 sDrive40i, X6 xDrive40i, and X7 xDrive40i vehicles. The connection between the 48-Volt battery and the starter-generator may not have been assembled properly, which can cause increased electrical resistance at the connections.

Consequence: Increased electrical resistance can increase the risk of a fire.

Remedy: BMW will notify owners, and dealers will inspect the connection between the 48-Volt battery and the starter-generator assembly, replacing it if necessary, free of charge. The recall is expected to begin April 12, 2021. Owners may contact BMW customer service at 1-800-525-7417.

BMW of North America, LLC (BMW) is recalling certain 2019-2021 X3 sDrive30i, X3 xDrive30i, X3 M40i, X3M, X4 xDrive30i, X4 M40i, M550i, X4M, X5 sDrive40i, X5 xDrive40i, X5 xDrive50i, X5M, X5 M50i, X7 xDrive40i, X7 xDrive50i, X7 M50i, Alpina XB7, 330i, 330i xDrive, M340i, M340i xDrive, and 8 Series Coupe, Convertible and Grand Coupe, 840i, 840i xDrive, M850i xDrive, M8, 2020-2021 530e, 530e xDrive, 330e, 330e xDrive, 745Le, 745Le xDrive, X5 xDrive45e, X3 xDrive30e, X6 sDrive40i, X6 xDrive40i, X6 xDrive50i, X6 M50i, X6M, 530i, 530i xDrive, 540i, 540i xDrive, M550i xDrive, M5, 740i, 740Li, 740Li xDrive, M760i Drive, M760Li xDrive, 750Li xDrive Alpina, Alpina B7 xDrive, and 2021 4 Series Coupe 430i, 430i xDrive, M440i xDrive vehicles. When shifting into Reverse, a small portion of the rearview image may be obscured, or the screen may not illuminate. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."

Consequence: If the driver relies on only the rearview camera image, the missing or reduced rearview image view can increase the risk of a crash or injury.

BMW of North America, LLC (BMW) is recalling certain 2021 430i and M440i 4 Series Convertible vehicles. In certain side-impact crashes, the head-thorax air bag may not deploy as intended.

Consequence: An air bag that deploys incorrectly can increase the risk of injury in a crash.

Remedy: Dealers will update the software, at no charge. All affected vehicles are still in dealer inventory, and therefore no owner letters will be mailed. The recall began March 9, 2021. Owners may contact BMW customer service at 1-800-525-7417.

The passenger seat belt Automatic Locking Retractor (ALR) may deactivate early, before the webbing fully retracts. As such, these assemblies fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."

Consequence: During a crash, a seat belt retractor that does not function as intended increases the risk of injury.

Remedy: Dealers will inspect the seat belt retractors (including the seat belts) and, if necessary, replace the retractors, free of charge. Owner notification letters were mailed on September 3, 2021. Owners may contact BMW customer service at 1-800-525-7417; 1-866-825-1525 (MINI); 1-877-877-3735 (Rolls Royce); and 1-888-270-9371 (Toyota).
