SEAT BELTS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, SEATS
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.

SEAT BELTS
Both the driver and passenger seatbelts have been replaced due to wear and shredding. Dealership has told us it was caused by the seatbelt extender “becoming delaminated” in both cases. This seems like a design flaw given the age and relatively low mileage (30,800). The more severe damage in the photograph is the driver’s side. The other is the passenger side that we proactively had replaced while the vehicle is still under its new vehicle warranty.

STEERING:LINKAGES:TIE ROD ASSEMBLY
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.

ENGINE
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 SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I am complaining about my new $ 79,000 BMW 440i that I just took possession of. I found out that the speedometer doesn't really tell you how fast you are driving. In SD the max speed on our interstate is 80mph. However, in my new car when the speedometer says you are going 80mph you are really only going 76mph. I consider that a serious safety issue since you never really know how fast you are going in any given situation. I also own an Audi S4 and when it says you are going 80mph, you really are going 80mph. Also, all my American cars give you the real speed at which you are driving. I can't believe our automobile safety laws permit this. [XXX] Vermillion SD INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER
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.
