2022 BMW X3 Lane Departure Problems

Vehicle: 2022 BMW X3 sDrive VIN: [XXX] Incident Date: [XXX] A BMW dealership technician discovered that the rear radar sensor (used for blind spot detection) was misaligned due to impact damage behind the bumper. The inspection notes stated "fault present 35 times" and showed missing screws and signs of prior repair. These safety features are critical to safe lane changes and accident prevention. The vehicle was sold as Certified Pre-Owned, and the dealership never disclosed this safety-related defect. This raises serious questions about whether the vehicle had been in a prior collision and whether the blind spot safety system is fully functional or properly calibrated. The dealership later claimed the vehicle was repaired but refused to provide documentation. I have no way to verify the sensor was ever fixed to federal safety standards INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This BMW vehicle's odometer readings are inconsistent and inaccurate resulting in overage of mileage for lessee. This cars BMW tires were not verifiable to be from BMW and tires subsequently failed within 15,000 miles. No entity at BMW, not the dealership, not the sales, not BMW Financial Services or BMW of North America LLC could provide any information regarding the original tires or provide any warranty information regarding the tires - this impact mileage efficiency, miles per gallon and is a way to game the systems. BMW front sensors on act erratically sometimes working and sometimes going off without anything present, during rain/snow sensors would constantly go off for no reason. Issues have been raised through certified mail to BMW and all have been ignored. There is no accountability regarding the tires with no warranty that fail, inaccurate odometer readings, car sensors and we request an investigation into these three matters.

The BMW front facing kafas camera system is prone to failure in the BMW X3. The plastic piece that holds the camera module in place has small plastic tabs that attach it to the windshield. These tabs are prone to breaking. Once the tabs break the front camera system is no longer in alignment and all front safety systems will be disabled. This puts the occupants of the vehicle in danger as all front facing safety systems will be disabled. The dealers do not want to warranty these failures as they try to pass it off as the fault of the owner. The first dealership rejected my issue saying that since my vehicle has a modified suspension that the camera is not able to calibrate which is incorrect. The second dealer I took it to saw the problem was the failed plastic mount but since my front windshield is aftermarket UV rejecting film it must have been damaged by the individual that installed it. This is not the case since the film did not extend behind the plastic pieces covering the electronics. In order to get this issue fixed I to pay out of pocket $2000 even though my vehicle is still under warranty. This issue has been reported by several people on various BMW forums.

Mount for BMW KAFAS camera melts/deforms in the heat (normal exposure). This causes the camera to become uncalibrated and disables Pedestrian avoidance braking as well as lane keep assist. I am unsure what other functions are unavailable. After 2+ months of waiting for a new part, the BMW dealer nor BMW NA could not give a timeline on when the windshield/mount would be available for replacement. This means that the safety features that were advertised and paid for by the owner are unavailable to the owner for an indeterminate amount of time. Forum participants indicate that this is a common problem with this model with some owners experiencing multiple failures of this safety system in a short period of time during summer months.

The main windshield bracket holding the front camera (responsible for Driver's Assistant including front collision warning, pedestrian warning, lane departure warning, etc.) has the tendency to break on its own. The bracket is made of thin plastic and can melt under direct sunlight and/or usage of vehicle as the camera gets hot as well. Any reasonable exposure or usage will eventually cause the bracket to melt/deform and fail, causing the camera to fall from its original position. The misalignment of camera will cause a cascade of error codes and completely fail to work, rendering the entire safety systems to be useless. The bracket itself is not sold separately and requires the manufacturer to install a completely new windshield which is the only method of fixing this issue. Manufacturer and/or dealerships refuse to warranty if preventative methods are used (such as windshield tint) even though the camera or mounts remain untouched.

There is a failure with the camera not being able to calibrate and a number of error messages

The clips that hold the KAFAS camera system are faulty and easily break. The KAFAS unit gets exceptionally hot and damages the clips causing the unit to go out of alignment and then cause all of the safety features to fail. The fact that you have to replace the whole windshield to repair two small plastic clips is an egregious mechanical design failure, waste of resource, and just insane design.

instrument cluster sporadically working. front collision and lane departure not working when the cluster isn't working. unable to judge speed accurately, Yes problem has been reproduced by Sandy Sansing BMW in Pensacola FL.no the part hasn't been inspected.no other warmings but have had warnings since that the driver assistance restricted. Frontal collision warning, pedestrian warning . I have been given a time frame to fix this as completly unknow- forcing me to drive this car without working instruments.
