BMW dealer noted "clunk on accel" at 57,152 miles on RO #224018 under engine mounts. Dealer quoted $3,463.38 for engine mounts. I declined repair. Clunk on acceleration is still present at 60,700 miles. Same symptom as BMW Service Bulletin SIB 27-02-20 for 4 Series Drive jerking/shuddering from…
BMW dealer noted "clunk on accel" at 57,152 miles on RO #224018 under engine mounts. Dealer quoted $3,463.38 for engine mounts. I declined repair. Clunk on acceleration is still present at 60,700 miles. Same symptom as BMW Service Bulletin SIB 27-02-20 for 4 Series Drive jerking/shuddering from transfer case. Transfer case was serviced by non-BMW shop prior to my ownership (unknown fluid spec). Dealer documentation only notes clunk on accel and engine mounts/alignment. Requesting investigation as this matches known transfer case defect with lifetime fluid claim. Vehicle is just out of 4yr/50k warranty.

The engine starter motor system failed, specifically involving an intermittent no-start condition related to a pinion starter line break / internal component defect. The vehicle and all original mechanical components are fully intact and available for professional inspection upon request. The engine starter motor system failed, specifically involving an intermittent no-start condition related to a pinion starter line break / internal component defect. The vehicle and all original mechanical components are fully intact and available for professional inspection upon request. The vehicle is currently experiencing these active symptoms. The vehicle experiences sudden, unpredictable intermittent no-start scenarios. Being unable to dependably start or restart the engine creates a severe risk of stranded occupants in hazardous traffic scenarios, remote areas, or extreme weather conditions. Furthermore, this failure pattern matches identical 2026 BMW starter recalls where internal mechanical wear creates a severe overheating condition and an elevated vehicle fire risk, directly threatening passenger safety. No, the component has not yet been formally inspected by the manufacturer, police, or insurance representatives since it has not resulted in an active collision or fire. It has only been scanned for diagnostic error codes. The symptoms are intermittent no-start events that happen unexpectedly from a complete stop. Diagnostic system scans revealed software errors specifically pointing to fault code XXX indicating a line break in the pinion starter. These symptoms first began appearing intermittently earlier this year. VIN: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
Service bulletins
Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.
- 10250374An interference noise (groaning noise) can be heard from within the heating and air-conditioning unit in thecenter of the instrument panel. The groaning noise always occurs when either a ventilation flap, air stratification flap or the recirculated airflap moves to a different position. Due to the complex design of the heating and air-conditioning unit, the kinematics causing it (top or bottom,left or right) may not be able to be precisely located. Depending on the vehicle model, the number of servomotors (and the associated kinematics unit) varies.Various models use either 2 or 3 servomotors.
