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.
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.
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.
