WBA7U2C00MCF526452021 BMW 750ixDrive

I purchased a vehicle from Ed morse Cadillac on 12/31/2025. I find out in April that the vehicle was sold with undercarriage damages listed in Carfax. The dealership, never disclosed anything, did not show me the reports, and i did not sign anything to accept the damages. They do not want to take responsibility. The vehicle might be dangerous to drive and is really demeaning in value because of this.

I am filing this complaint regarding an ongoing safety issue with my 2021 BMW 740i involving the lane departure warning system, lane keep assist, and adaptive cruise control, all of which have stopped functioning properly. These features are critically tied to the windshield-mounted KAFAS camera, which I’ve now been told needs to be replaced. Initially, the BMW dealership attributed the issue to a software problem and charged me $500 for a software update. After the update, the driver assist systems remained non-functional. The dealership then diagnosed a failure with the front camera assembly and is now quoting me approximately $3,000 for replacement of the windshield and camera module. I have reviewed NHTSA Technical Service Bulletin SIB 66 08 23 (NHTSA ID: MC-10236236-9999), which outlines this exact issue, suggesting that BMW is aware of system limitations and hardware failures in this critical safety feature. However, this has not resulted in a recall or manufacturer-paid repair, despite the significant safety risk involved. I am requesting that NHTSA investigate this issue for the 2021 BMW 740i and similar BMW models equipped with the same KAFAS camera system. The sudden failure of key driver assistance systems—especially lane departure warning and adaptive cruise control—can lead to dangerous driving conditions, particularly on highways. I believe a recall or service campaign should be initiated requiring BMW to cover the cost of diagnosis and camera replacement due to the safety-critical nature of these systems. Please consider this complaint as a formal petition for further investigation and potential recall.

The contact owns a 2021 BMW 750I. The contact stated that upon start the vehicle, the low tire pressure warning light illuminated. The contact initially took the vehicle to the dealer and an independent mechanic however, the cause of the failure was not determined. The failure persisted and the contact took the vehicle back to the independent mechanic who discovered a crack in the rear driver’s side rim. The tire was replaced; however, a month later, the same failure occurred on the front passenger’s side rim. The vehicle was taken back to the independent mechanic where he was informed that the failure was common with the model vehicle. The tire was replaced. Recently, the failure occurred on the front driver’s side rim. The dealer was notified of the failure and offered insurance to cover the cost of future tire repairs. The manufacturer was not notified of the failure. The most recent failure was repaired. The failure mileage was approximately 25,000.
