Defect. BMW of North America, LLC (BMW) is recalling certain 2019-2022 330i, 330i xDrive, M340i, 2022 430i Coupe, 2021-2022 430i, M440i Convertible, and 2020-2022 228i xDrive Gran Coupe vehicles. The receiver audio module control unit software may fail to properly generate audible seat belt warnings to the driver to fasten their seat belt. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."

Risk. An audible chime that does not properly alert the driver to fasten their seat belt increases the risk of injury in a crash.

Remedy. Dealers will update the receiver audio module software, free of charge. Owner notification letters were mailed October 12, 2023. 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."

Risk. 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).

Defect. 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.

Risk. 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.

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."

Risk. 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.

Remedy. BMW will notify owners, and dealers will inspect the rearview camera software and update it if necessary, free of charge. The recall began April 16, 2021. Owners may contact BMW customer service at 1-800-525-7417.

Seat Belts

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 the car but worry this is a safety issue forums are mentioning. Car alarms 1m-4am is that software updates, went on for four days in June.

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 hot coolant and shards of metal shooting everywhere as my son was on the highway being passed by big trucks. Weren't going too fast as we were just getting on the highway merging in which was also dangerous as everyone else was going fast. BMW has given me the runaround from department to department on this even though they all seem to agree that mine should be part of the recall or already fixed which was obvious because the new part is made of a different material than the old original part. On their service action my car is the G22 series clearly listed

Brought a New 2021BMW M440 only 5 months ago, garage kept, has less than 4,000 miles. I woke up with a 10” crack across windshield @ 6:30 am on 9/28/2021with popping sounds. Windshield was shown on camera the night prior with no damage and shows no apparent evidence of ever getting hit. No scratches or chips. On 9/29/21 @ 7am car had more popping sounds and now crack has reached 15” - increased. By 5 “ after measuring. Dealer inspected 9/28/2021 and only states windshield has to be replaced and only stated the changed in temp of 80 degrees and dropping to 60 degrees @ night could have been the factor for cracking.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
