While driving our BMW 2019 X3 on the highway, other drivers honked to get my attention that our vehicle's rear hatch was partially open. When we came to a stop light, I had my son riding in the passenger seat press the hatch button on the key fob to close the hatch. Instead this fully opened the back hatch. We continued pressing the fob button in an attempt to get the hatch to close without having to exit the vehicle. Rather than exit the vechicle in the middle of the roadway, we drove about 50 yards until we could pull over safely. A motorcyclist had been following us, and came up behind and communicated that he wanted to press the button to close the hatch. After I gave my consent, he pressed the close button and the hatch closed and latched. My husband has previously had incidents where after parking the BMW, he finds the back hatch open. He's also researched online this is apparently an issue.

I am reporting a safety defect involving a 2024 BMW X3 xDrive30i. The vehicle continued operating for several miles with no key inside the vehicle, and at no point did the car display a “Key Not Detected” warning, icon, or audible alert. Two minors were present during this incident. This indicates a failure of the key-recognition system, immobilizer logic, and associated warning functions. BMW’s safety system should detect the absence of the key and immediately warn the driver. Failure to issue a warning presents a significant safety hazard, as the driver may unknowingly operate the vehicle without the ability to restart, secure the car, or be alerted to a loss of security control. BMW Roadside Assistance documented the incident. BMW North America has not provided a case number, safety review, or written plan for addressing the defect despite multiple requests. This lack of response is concerning for a safety-critical malfunction. I am requesting the federal safety agency’s review of this defect and BMW’s handling of the matter.

The driver side rear door locking mechanism keeps locking, even when the car is unlocked with the key fob. This is a safety concern, as our granddaughter rides in the rear seat regularly and if an emergency arises where I need to get her out of the back seat quickly, the rear door can stay locked and not allow me to get her out. There were no warning notices for this issue on the dashboard system.

I own a 2024 BMW X3 that has developed a recurring and unpredictable safety issue with the tailgate. Without any input from me — and without pressing the key fob, tailgate button, or any switch — the rear tailgate will open on its own. This has occurred multiple times while the vehicle was parked, locked, and unattended, and it has also happened shortly after driving and parking. I brought the vehicle to an authorized BMW dealership for diagnosis under warranty. The dealership inspected the vehicle but was unable to identify the cause and returned the vehicle without repairing the problem. Despite my request for further escalation (such as opening a technical case with BMW’s engineering team), the issue remains unresolved. This defect poses a significant safety risk. An uncommanded tailgate opening could result in the vehicle’s contents falling out, create a road hazard, or lead to injury to people nearby. It also increases the risk of theft or water intrusion into the cargo area. The problem is intermittent and unpredictable, but it continues to happen. I am submitting this report because the issue remains unresolved by the manufacturer and could endanger both occupants and the public.

Today, I placed my backpack containing my 2019 BMW X3 key fob in the back seat, closed the door, and proceeded to open the driver’s door as usual. Immediately, the car locked itself with the key fob still inside. This is a failure of the anti-lockout safety system. The vehicle’s Comfort Access/keyless entry system is designed to prevent the doors from locking when the key is inside, and it should never lock itself under these circumstances. This malfunction creates a serious safety risk, as occupants or pets could become trapped inside the vehicle. I am submitting this complaint to notify the federal safety agency of a potential safety defect in the BMW anti-lockout / Comfort Access system. I request an investigation to determine if this defect affects other vehicles of the same model and year.

The car has keyless ignition and was accidentally left on/idling in the garage despite no one in the car and the key fob not present. The car was on for 8.5 hours in the closed garage and filled the house with exhaust, which includes dangerous carbon monoxide fumes, known to be lethal and nearly ended in tragedy. Luckily, my wife woke up for an unrelated reason to check on our daughter and smelled the fumes in the house and found the car running in the garage. Multiple carbon monoxide detectors were in the home and did not go off, so presumably the fumes had not yet reached toxic concentrations by the time the car was turned off. 2 days later, I took the car to the BMW dealership to be inspected for defects and was told by the technician that it was functioning properly and I should assume the engine is running if the keyless ignition button is not turned off. The lack of an auto-shutoff safety feature to prevent this occurrence is completely unsafe and unacceptable. This is a known issue of keyless ignition cars for over a decade and is an easy mistake to make given how quietly the cars run. Many other car manufacturers have already implemented this feature, so it was shocking that such a well-respected car brand like BMW did not include this safety control as a default feature.

On two separate occasions, the BMW has completely shut down in the middle of the road while driving. An alert showing something along the lines of "drive train failure" was shown on the dash display, and I simply had no control over driving the car. Upon making it safely to the side of the road, the car would not start, only sputter, when the push button start was engaged. After the first incident, the car was towed to a shop where they stated it was the high pressure fuel pump that needed to be replaced and stated there was a recall for this exact issue; however my VIN is not in the recall. Somehow, the car started working again and seemed okay, until it happened a second time, in the middle of the road AGAIN. Took it to a new shop, and received the SAME information, same part, same recall suggestion, with my VIN still not falling into the recall. The recall is for my exact year, model, engine number, everything - just not my VIN. It does not make any sense. The recall that number that should be covering this is 21V‑586.

On the 2019 BMW X3, we’ve experienced the tailgate opening while the vehicle is in traffic, and the transmission is in ‘D’ drive. The safety hazard I’m suggesting be investigated is that the buttons on the remote key fob to the vehicle, including lock, unlock, tailgate, and panic, ALL work even if the vehicle is turned on and driving. This poses a serious safety risk to not only occupants of the vehicle, objects or animals that may be in the trunk, but also to other motorists on the road. We’ve personally had this happen three times, all in cases where we were in live traffic on an active roadway. One case in particular our dog was in the trunk and we had to pull over in the middle of traffic while the dog thankfully stayed seated in the trunk area. I believe this happens because it’s very common for the key fob to be in a pocket or purse while operating the vehicle, where it’s very possible for the buttons to be pressed inadvertently. In my opinion, the key fob should not be functional while the car’s ignition is on. No other car I’ve ever owned has had a key fob whose buttons still work while the ignition is on. Happy give further comment if need be. Thanks

The contact owns a 2011 BMW X3. The contact stated that the vehicle was experiencing electrical failures. The contact stated that the door lock pins failed to go up or down while using the key fob. The vehicle was taken to the dealer, where it was diagnosed that the door lock actuator had failed. The vehicle was repaired; however, the failure recurred two weeks later. Additionally, the turn signals and the windshield wipers were inoperable while driving. The vehicle was taken back to the dealer, who informed the contact that the battery needed to be replaced; however, the contact declined the battery replacement because the battery was 5-month-old. AAA inspected the vehicle at the residence and informed the contact that the battery was in good condition. The vehicle was taken to an independent mechanic, who made the same assessment and diagnosed that the failure was related to the footwell module. The vehicle was not repaired. The contact related the failure to an unknown warranty extension program. The manufacturer was not notified of the failure. The failure mileage was approximately 57,486.
