2024 BMW iX Driver Assist & ADAS Problems

The car in front of me did not put brakes on or slow down and hit a car that was slowed to a stop in front of her. I was behind her and hit by brakes and tried to avoid the collision. My brake assist did not work; my car did not alert me and did not try to help me stop. I was told when i bought the car that it did indeed have these safety features which failed me. I was not sited in the accident even though i did end up hitting the car in front of me which was now attached to two cars in front of her. She was at fault and the car she hit had video footage to prove her fault.

I am reporting a serious safety failure in my 2024 BMW iX related to the Forward Collision Warning (FCW) and Automatic Emergency Braking (AEB) systems. Recently, my vehicle failed to detect a slowing car ahead, and the emergency braking system did not engage, resulting in a rear-end collision. This malfunction has caused financial loss due to repair costs and raises severe safety concerns, especially since my infant child was in the vehicle at the time. A functional AEB system should have prevented this accident. Given recent BMW recalls for braking system issues, I am deeply concerned that this failure is part of a broader defect. I urge NHTSA to investigate potential system defects in the 2024 BMW iX to prevent further accidents and protect lives. Please advise on the next steps for escalating this safety concern.

My 2024 BMW iX xDrive50 intermittently fails to deploy the rearview windows upon startup. Restarting does not help; they open only after driving above ~25 mph. This typically occurred once or twice a month based on my recollection. I purchased the vehicle in late May 2024, so I had it for only five months before the accident. More concerningly, the vehicle sometimes shifts from Drive (D) to Brake (B) mode without input. I noticed this behavior several times before a crash on 10/27/24, and again after the crash. On 10/27/24, while in B mode, I slowed at an intersection with ~30 feet of space ahead. I was practically at a stop and began to inch forward when the car suddenly accelerated and I lost control, rear-ending the car in front. No automatic braking or warning systems activated. BMW North America inspected the vehicle on 12/20/24 and later concluded that no defect was present after a 6-mile test drive. After their review, my dealership also conducted its own inspection but was unable to replicate the issues I reported. However, neither review addressed—or could replicate—the intermittent switching between D and B modes, which remains unresolved and unpredictable. BMW also could not explain or resolve the issue of the rearview windows failing to deploy. I am concerned that both issues may reflect a broader software or user interface flaw. I am also concerned that BMW’s investigation focused primarily on establishing that I pressed the accelerator pedal before the crash, as a way to default blame for the accident to me, rather than investigating whether a fault in the vehicle’s electronic input or feedback systems could have contributed to the incident. Given the safety implications and the limited scope of BMW's investigation, I request a deeper independent review.

Using BMW's Parking Assistant Professional feature, I recorded and saved a backup parking maneuver into my garage on 5/7/2024. The idea is that this saved maneuver can later be recalled and used as the car approaches the same location as where it was recorded. This function worked well the first 10 times or so that I used it. However, this past Sunday (5/12/2024), as I pressed on the touch screen to start this parking maneuver, the car did not perform the maneuver as it had the previous 10 times. Instead, the car went straight back and hit the wall. I have reported this glitch to BMW USA and have not received any response.

Issue 1- Car Starts to slowdown on its own when on self-drive mode on freeways – Has happened 3 X - service center has not be able to reproduce the error but many people on BMW forums has complained about the same in various driving conditions. Ours happened on a straight road with no car ahead of us but a car behind us which nearly caused an accident and a lot of anxiety . Our car went down from 70MPH to 40 and wouldn’t let me accelerate as well . Issue 2 - Front and Rear self-parking modes don’t work – Always have an error and goes in the wrong direction and doesn’t detect open spaces. For example it can’t decipher between grass and tarmac when the feature is being used in a driveway. Have recorded evidence and the BMW service station says the feature can’t be used on a driveway or garage- no documented evidence or information provided to us at the time of sale and till now . ( evidence of dealer notes also available) - Big safety issue as car goes on grass, hits garage walls, is reversing on side walks Issue 3 Reverse assisted parking doesn’t work flawlessly – even with the foot of the pedal it continues to speed and go fast - don’t think the service center even tried to duplicate this issue. All three are safety concerns for me and my family and is unacceptable. We have video recordings of the last two issues and screenshots are attached . The same have been shared with BMW but no one seems to care
