Sirrus XM Advertising pops up in the middle of the speedometer and stays there. Blocks vision of speedometer. Big Blue square comes on at night distracting driver. Several internet posts and complaints advise that it comes on blocking the rear camera vision. Contacted Sirrus they say they cant do anything about it, it is built into the car. Contacted BMW and their "Genius" squad they don't know how to get rid of it. I see postings of other car brands having the same complaint. Consumers don't spend $70.000.00 for a vehicle to be solicited for a service that they don't want. Besides the safety factor. This is an invasion of privacy and none requested solicitation. Please look into this.

Upon starting the vehicle, the electronic dashboard comes on, declares “Reduced Driver Assistance” then about 15 seconds later, the entire dashboard goes dark and won’t come back on until the car has been shut down for several minutes. This sequence of events happens 95% of the time that I start the car. Upon restart, the dashboard will stay on about 40% of the time, the other 60% it shuts off again. While I can still see my speed in the heads up display, I have no idea how much gas I have, I can’t get any information from the dahsboard and I can’t use the cruise control. I’ve read about other owners of the 2021 BMW X3 M40i having this same issue however the dealership seems to have no idea and wants me to spend $1,000 in diagnostics to see if they can find the problem….then I would ha

The malfunction involves the collision warning system and sudden braking functionality. The dealership inspection identified a problem with the KAFAS (camera) unit, specifically its housing being deformed from heat, which affected the functionality of the collision sensor and caused the system to malfunction intermittently. The component is still installed in the vehicle and available for inspection if required. The system triggered sudden braking without an actual threat, creating a serious risk of being rear-ended by vehicles behind me. This issue has occurred twice in the last month, with no warning or actual collision risk present. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the problem was confirmed by the dealership. Their inspection

During rain this evening, water intruded from sunroof area. Learned this is extremely common problem alleged to be due to shrinking sunroof seals. This dripping water can potentially cause loss of control of the vehicle due to falling water intrusion causing foot controls to become wet. In addition, electrical malfunctions may occur possibly causing fire or other problems. I am also including a stranger’s video of his car at BMW dealer with tech explaining this is a very common problem, obtained from Facebook.

Driving on a highway with occasional traffic lights, my 2021 X3 Plugin hybrid's sunroof's from glass cracked with a loud bang. I had it closed and the sun shade part also was closed. The loud bank also felt like an impact on my head and I felt in a bit of a shock like the time I was hit from behind with a shock and having to think. I first though it was a tire and slowed down to safely exit into a business parking lot to asses the situation. After checking the tires I noticed something on the roof. The glass was cracked and deformed in an upward direction. It was still pushing upward and a 4-6 inch section fell off and onto the top of the sun shade part. In safety, the loud shock caused a brief distraction on a highway going at least 50 MPH. Also if the sun shade was open some of the glass

The contact owns a 2021 BMW X3. The contact stated that the tailgate would fall on the contact without warning upon use. On one occasion, the tailgate had fallen on her left arm and the contact had to wrestle her arm out of the vehicle as the tailgate sensor failed to recognize her arm. Once her arm was released, the tailgate locked her purse inside the vehicle. The contact did not suffer any injuries. The contact called the dealer and arrangements were made to drop her off at home and to take her back to the vehicle once a spare key was made. The contact also stated that the car alarm would independently activate without warning while being driven and while stationary. The manufacturer was not notified of the failure.

Brightness adjustment for control display screen (backup camera, navigation,messages etc) has been eliminated from menu. Driver has no way to adjust daytime brightness anymore. BMW replaced it with a interior brightness sensor in the upper left corner of the instrument cluster above the gas gauge. The danger incurs because the screen keeps changing brightness in the daytime based upon light entering the auto and hitting the light sensor. This happens coming out of a garage, tree lined street, cloudy day etc. The danger is that you cannot observe things clearly using the back-up camera, and using navigation during the daytime you cannot make out directions, roads, highways etc because the screen turns a dull white or almost gray at times. This forces you to star at the screen or get cl

The headlights will turn on and off irregularly without any drastic changes in outside lighting conditions while set in the Auto setting. No controls will be touched and the lights will turn on and off completely by themselves. It appears something is wrong with the lights switch assembly, as if something is shorting / wire is pinched. Other owners online forums have experienced similar issues as well. Can become a serious problem if it occurs while driving, especially in dark conditions.

Vehicle is not alerting driver that flat tire has occurred. Especially problematic as vehicle has run flats. Pressure sensors are working correctly, and accurately reporting PSI and temperature. Software automatically "resets" tire pressure based off of tire size and set speed, this is not something that a user can control. In other words, I can't "reset" the sensors when the tire has 10 PSI, so that it will think that that is normal. Asked if others have seen similar issues in a forum: [XXX] Right away someone else has had newer car to dealer multiple times with the same issue.

My car's speedometer only displays speed in 10 miles increments, which makes it nearly impossible to know exact current speed of the car. For example when speed is between 50 and 60 I can only guess what my actual speed is, 52 or 58. BMW for some strange reason sells an optional package which enables accurate digital speedometer, and I think accurate speedometer must be standard. This is a safety issue.
