Crash test ratings
NHTSA NCAP crash test ratings
New Car Assessment ProgramNCAP crash tests measure how well a vehicle protects occupants in controlled frontal crash, side crash, and rollover scenarios. Stars are awarded per category (5 = safest). These laboratory results are independent of owner complaints and are performed by NHTSA engineers on new production vehicles.
NCAP crash test ratings for this model are not yet loaded or this vehicle was not tested in the years analyzed. NHTSA tests a subset of new vehicles each year. Check nhtsa.gov/ratings directly for the latest results.

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
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 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.
The contact owns a 2025 BMW M440I. The contact stated that on several occasions while driving at speeds under 20 MPH, there was an abnormal clunking sound coming from the steering column. The vehicle was taken to the dealer where it was determined that the tie rod assemblies needed to be replaced. The vehicle was not repaired due to parts not being available. The manufacturer was notified of the failure. The failure mileage was approximately 3,500.

The basics
How to read this data
Complaints, recalls, investigations — here’s what each number actually tells you about a used BMW M440i, in plain English.
What is an NHTSA Complaint?
An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is — but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The BMW M440i has 5 complaints on record across 6 model years.
What is a Safety Recall?
A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The BMW M440i has 9 recall campaigns in the NHTSA database.
What Are Crash Complaints?
Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 1 of the BMW M440i's 5 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions — a key safety signal beyond general reliability.
How Is the Reliability Verdict Calculated?
The reliability verdict (Excellent) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. This verdict gives buyers a quick interpretation before they review year-level details and VIN-level history. It should be treated as one decision input, not a substitute for a VIN-specific report.
Why Do Newer Years Have Fewer Complaints?
Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable — simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.
Fleet Data vs. Individual VIN
Everything on this page reflects aggregated data across all BMW M440i vehicles on the road — not any specific car. Two BMW M440i vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.
What Are NHTSA Investigations?
When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage — NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The BMW M440i has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
