2023 BMW X3

I am submitting this complaint regarding a recurring coolant leak and cooling-system issue with my 2023 BMW X3. I began receiving repeated “low coolant” warnings on the vehicle's dashboard. The coolant was topped off, but the warning continued to return, indicating that this was not simply a low-fluid or routine maintenance issue. The vehicle was subsequently inspected by BMW, and a coolant leak was identified in the engine compartment. I was informed that certain components associated with the cooling system were made with plastic and were exposed to significant heat, which contributed to the components failing and causing coolant to leak. BMW ultimately had to replace the affected components with newer/upgraded replacement parts. The fact that the replacement components were newer than the components originally installed in my vehicle raises concerns that the original parts/materials may not have been adequately designed to withstand the operating temperatures and conditions of the vehicle. I am concerned that this could represent a premature component failure or potential design/material defect affecting the cooling system of 2023 BMW X3 vehicles. A coolant leak can potentially lead to overheating, engine damage, loss of vehicle performance, or a vehicle becoming disabled while being operated. I also believe it is important for BMW and NHTSA to investigate whether other vehicles equipped with the same components are experiencing similar premature coolant leaks or failures. I am requesting that this complaint be documented and considered as part of any investigation into cooling-system or coolant-leak issues affecting BMW X3 vehicles. I have documentation of the repair, including the diagnosis and the parts that were replaced, and can provide those records if needed.

I am submitting this complaint regarding an unresolved safety recall on my vehicle. The recall has been outstanding for approximately three months. and I have been informed that there is still no remedy available. I understand that some recalls may require time for manufacture to develop and distriubute a repair, however , this is a safety related recall and leaving consumers with a known safety defect for months without an available remedy creates a serious concern. I have tried to raise a concern about not feeling safe driving the car , however they seem to not care about the concept. What concerns me the most is that I am being asked to continue living with a vehicle that has already been determined to have a safety related defect while there is no clear timeline for when the repair will become available. I am requesting that NHTSA review this recall and the manufactures handling of the delayed remedy, including weather adequate interim safety measures and communication are being provided to affected vehicles owners because I am not getting anywhere with BMW regarding my safety. I would like clarification regarding: 1-Why the remedy had remained unavailable for approximately three months 2-what steps are being taken to ensure that affected owners are not left exposed to a known safety defect indefinitely. I believe consumers should not have ti wait to an Idefinite amount of time for a repair after a manufacture has determined that a safety defect exists. I respectfully request that NHTSA review my complaint and determine weather further action or oversight is warranted. Thank you

On 8/11/2026 at 26,039 miles, BMW of Mt. Kisco (NY) replaced the engine starter under safety recall B121026 (RO #123380). On 8/29/2026, 331 miles later, the vehicle failed completely. It would not start, displayed an "engine starter faulty" message, and could not be shifted out of park into neutral. The vehicle was completely immobile and had to be towed to the dealer. The dealer's repair order states the technician connected a battery charger, found BDC (body domain controller) faults for the starter motor, and performed a battery reset and BDC reset, after which the vehicle started. No root cause was identified and no parts were replaced. The battery was subsequently load tested and found normal, ruling out low voltage as the cause. My concern is that the vehicle suffered a complete loss of module communication in the same system addressed by the recall remedy, only 331 miles after that remedy was performed, and was returned to me with the fault cleared but undiagnosed. Because the vehicle could not be shifted into neutral, it could not be pushed or rolled clear. Had this occurred in moving traffic or at a rail crossing rather than at rest, it would have created a serious hazard. The failure is unexplained and therefore may recur.

Mileage: 31,694 (bought [new]) The engine starter intermittently fails to crank the engine and, per an open manufacturer recall, presents a fire risk while the vehicle is running. On multiple occasions the vehicle struggled to start during normal use. There was no crash, no injury, and no airbag deployment. To isolate the issue I contacted my authorized BMW dealer three times 07/01/2026, 07/16/2026 & 07/27/2026; on each call I was told no recall remedy is currently available and to call back in approximately one month. The vehicle remains subject to the open starter recall with no repair available. No relevant aftermarket equipment is installed.

On the evening of Wednesday March 6th 2025, as I turned into the street where I live, my car became difficult to steer. It felt like I had developed a front flat tire on one side, but there was no indication of low tire pressure on the dash. I was moving around 5 miles an hour and with some difficulty, could navigate the car to the curb on my street and park it in front of my home. I could not attend to the car on Thursday or Friday since I was busy at work. On Friday night I contacted BMW towing and arranged the car to be towed on Saturday to the dealer from whom I had purchased the car. The dealer confirmed that the car was not steerable. They put up the car on the rack and sent me a video. They noted that the left tie-rod steering linkage was broken. They noticed scratches on the under side of the car, and "Curb rash" on the wheels suggestive of possible brushing of the front wheels to the curb which may have caused the steering problem. They indicated that because it was caused by accidental damage, it was not covered under warranty. I cannot recall any accidents, big or small , while driving this vehicle. I have brushed along curbs occasionally, but none that should break a steering linkage. The scary part of this whole thing was how I could not steer the car, fortunately it happened at low speeds. It could have been worse if the disruption had occurred at freeway speeds. If a car can become non-steerable by just hitting the curb, because the steering linkage broke, that is not acceptable level of quality from a safety standpoint. I would expect better performance from a BMW. I can understand the car getting out of alignment, but to lose the ability to steer is just not acceptable. I have attached pictures of the broken linkage from the video that was sent by the dealer. I have attached the pictures from the

Due to an implementation error in various OBD diagnostics in the vehicle's control units, in very rare cases itmay happen that stored fault memory codes (DTCs) and the MIL (warning light) are not automaticallydeleted even though the underlying malfunction has already been rectified. This does not comply with the statutory OBD specifications.
