The operating system is yielding extremely poor results. After purchasing the vehicle, the operating system wouldn't remember the settings for the selected driver and would randomly changing settings. At one point, the turn signals on the vehicle stopped working because of the issues with the operating system. This is a direct violation of safety laws and effectively deemed the vehicle undriveable. The vehicle was serviced by the dealer, at which point they stated that there was a communication issue in the vehicle and that it was solved. The vehicle then performed well for about six months, but is now exhibiting the same issues, but manifesting in different ways. One example is where the displayed speed of the vehicle on the dash doesn't align to GPS speed readouts, and the value changing between startups. On a recent trip, I had the speed set by cruise control at 80mph on the dash, however was confirmed at 76 via GPS. After stopping and restarting the vehicle, I set the cruise back at 80, and now the GPS showed 79. This tells me that the operating system of the vehicle is randomly choosing how fast the vehicle is actually traveling, and how many miles are being put on the car. If the manufacturer can control this, they can determine how quickly vehicles achieve certain mileage benchmarks without the public being aware. This is very much a safety concern, in addition to BMW committing fraud. I have zero tolerance for an organization committing fraud.

2022 BMW X3 M40i. The Driver Assistance system appears to activate normally after startup with no warning or indication that a fault is present. However, within approximately 3–5 minutes of driving, a Check Control message appears stating “Driver Assistance limited. Camera vision.” The vehicle then identifies affected systems including Pedestrian Warning, Frontal Collision Warning, Side Collision Warning, Automatic Lane Change, Active Blind Spot Detection, and Steering Assistant. A separate message states that Active Cruise Control is reduced and there may be no brake intervention for stationary vehicles. The safety concern is that the system can appear active and available before the warning appears, even though at least some driver-assistance functions may already not be operating. Before the warning was displayed, I observed that Steering Assistant/lane-keeping did not intervene and I crossed out of my lane without steering correction or a lane-departure warning. There was no prior warning that the camera-based system was malfunctioning. I cannot confirm whether the other affected safety functions were operational during this interval. A BMW dealer inspected the vehicle and physically found the KAFAS camera hood/trim warped from heat. The warped component was removed and shown to me, and the dealer ordered a replacement. BMW has issued SIB 66 13 23 addressing KAFAS camera hood deformation on affected vehicles. Fault memory also contained KAFAS codes 800ABF, 800ABE, and 800AC4 for camera field-of-view disturbance and calibration failure. This creates a potential safety defect because the driver may reasonably believe lane-keeping and other camera-based safety systems are functioning until the vehicle detects the failure several minutes later. The vehicle/component can be made available for inspection

While actively driving at speed, the vehicle's Driving Assistance Professional Package (DAPP) completely deactivated without warning. This caused an immediate, unexpected loss of both adaptive cruise control and active lane-keeping steering assistance, requiring sudden manual emergency intervention to maintain control of the vehicle and avoid a collision. This is a severe safety defect. The vehicle has been presented to an authorized BMW dealership twice for this exact failure. It is currently on its second repair attempt and has been out of service for about 30 consecutive days. It is stilll in the shop. The dealership and manufacturer have been unable to permanently resolve this electronic/steering system malfunction. Additionally, they gave me another 2025 BMW X3 VIN [XXX] which experienced the same problem yesterday 3/28/2026 while I was driving about 35 miles per hour on the freeway.

Around April 2025, While driving at highway speeds for approximately 1hour with cruise control engaged, vehicle suddenly began to decelerate as if I had taken my foot off the throttle. Pressing the throttle had no effect on engine RPM or vehicle speed as the vehicle continued to decelerate. Tapping the brakes then pressing the throttle had no effect as vehicle continued to decelerate. I was able to negotiate across lanes of highway traffic at low speed to reach shoulder with no throttle control. After coming to a stop on the highway shoulder, pressing the throttle failed to rev the engine or move the vehicle forward in drive. After placing transmission in reverse, the vehicle did back up normally allowing me to put the car in a safer position on the shoulder. After turning off the ignition and restarting, the vehicle operated normally. I was able to complete my trip without incident. I did not engage the cruise control. A few days later, I took the vehicle to an BMW dealer service center but no error codes or malfunctions were identified. A second incident similar to the first occurred in August 2025. Again, I was able to reach the shoulder without serious incident. After turning off the ignition and restarting, the vehicle operated normally. I was able to complete my trip. I did not engage the cruise control.

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 have to pay to have it fixed as well. This seems like a pretty big safety issue.

I emailed BMW of Arlington on [XXX] detailing the critical safety issue I experienced with my BMW X3 2012 on Sunday [XXX]. I was driving on the tollway northbound from [XXX] in Grand Prairie in the pouring rain with my wipers on, and the car suddenly started braking and decelerating from the 70 mph cruising speed to 40 mph in seconds. The car behind me nearly hit my vehicle, and since it kept doing that, I had to turn on my hazard lights till I exited. The car was doing that irrespective of whether it was on cruise control or my driving speed. I discovered by googling it that this is a known defect in BMWs since their shop foremen and certified technicians who know more than me think I am dreaming this up [XXX] -. Driving this car on the highways in Dallas regularly is extremely dangerous as I could end up in a major multivehicle MVA pileup. Also, the previous time I had this issue before I brought it in on [XXX], it wasn't raining, and it started with the car not even moving when I put it in reverse and pressed the gas. Then it suddenly started decelerating on the road, backfired, and shook violently at normal speeds. The car overheated as the radiator coolant leaked, and I had to replenish it. CarShield, the Auto Warranty company, and I paid approximately $7,000 to BMW Mini of Arlington between June 2023 and today (see attached invoices_receipts_diagnosis reports). The last two times ([XXX] and [XXX]), their multi-point diagnosis on my vehicle identified no issues that need attention. Two of their service advisors who worked on my car in June and October 2023 quit immediately after completing it. The dealership does not respond to the BBB or my calls, emails, faxes, etc. BMW USA advised me to contact the federal safety agency. On June [XXX], while driving on city streets, the brakes were squealing even without engaging, and the car overheated/ backfired again/ almost caught fire.
