The 2021BMWM440I carries 3 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 1 crash, 1 fire, 2 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2021 M440I is unknown or other with 1 filings, followed by service brakes (1) and engine (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 5 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 34 investigation files overlapping the 2021 M440I. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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
Vehicle brakes malfunctioned.
Brought a New 2021BMW M440 only 5 months ago, garage kept, has less than 4,000 miles. I woke up with a 10â 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 15â - increased. By 5 â 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.
