Bmw
X3

I am reporting a manufacturing defect on BMW vehicles, specifically the 2019 BMW X3 with fewer than 40k miles. According to a vehicle inspection conducted at a BMW dealership on Saturday November 22, 2025, the motor mounts are collapsed. Potential risks are excessive engine vibrations that could cause loss of control while driving, to engine components to fall off the ground while driving. It’s dubious that BMW dealers “discovered “ this issue after the vehicle warranty expired. I request that the matter be investigated and order the manufacturer to extend coverage to a minimum of 120k miles or 6 years from date of service. Please investigate before it’s too late. Thank you.

While driving my BMW X3, the engine suddenly failed after the check-engine light came on, which followed several days of intermittent high-temperature warnings. Coolant levels had been consistently monitored, refilled, and topped up as needed, yet the temperature fluctuations persisted. Upon further inspection, the repair shop determined that coolant had been leaking internally into the engine due to a cooling system failure, causing overheating and warping of internal components. This created a serious safety hazard, as the vehicle began losing power while in motion, leaving me unable to safely accelerate or maintain speed in traffic and increasing the risk of a collision and a potential fire. This is a serious matter and BMW should assume responsibility for this. I bought the car assuming it was reliable but having to endure this cost out of pocket for an engineering failure is not okay.

The emergency call system on the vehicle has failed and I am getting an error message. The service center at the dealership informed me that water ingress into the shark fin that houses the system caused the system to short and fail resulting in the need for a complete replacement of the system at a cost of $3100. BMW has issued a service bulletin (SIB 65 12 22-Roof Mounted Antenna Housing Seal Not Adhering) that states that the seal of the room-mounting antenna housing is separating from the vehicle. This will allow water ingress into the vehicle, possibly damaging components and equipment. With the correction of remove and reseal the roof-mounted antenna housing. During the service call, the technician confirmed this defect caused the issue. I contacted BMW and they refused to completely cover the repair stating it is not a safety issue. I disagree, I purchased the vehicle with advanced safety features. My wife travels with the car to rural areas and this feature is critical in her safety in the event of a crash. I feel BMW should cover the repair and that this issue is a safety concern for those who rely on an advanced safety calling system purchased with the car. In reviewing message boards, this seems to be an issue for many owners of BMW SUVs.

Despite replacing the water pump, coolant expansion tank, hoses, and other related cooling system components, and fully refilling and bleeding the coolant, the issue persisted. Even after these repairs, the engine continued to overheat and show coolant level fluctuations, indicating an underlying problem likely pressure buildup or head gasket failure that was not resolved by replacing standard cooling parts. Dealership has identified further problems and seem like a costly repair that I won’t be able to do out of pocket. BMW needs to address this issue immediately, engine stuttering and loss of sudden power on the high way is not safe!

2019 BMW X3 - Coolant warning has been going on for the last 6 months and I was refilling coolant every time it went off. I even had the car serviced and they refilled the coolant. Then I was driving the car the engine is overheating warning came on I pulled over. It cooled down. Car was fine but said it needed coolant. I added coolant and noticed it was leaking from multiple spots underneath the car. I had the car towed to a certified BMW mechanic. They did a diagnostic test and inspection and I was told the exhilarator water pump, coolant hose, coolant return line and oil filter house among a list of other things need to be replaced. The repair is estimated at $4700.00

My 2019 x3 model has been leaking coolant from multiple places. I have already needed to replace the water pump at my mechanic and now there's an additional coolant leak and the radiator and radiator hoses are affected and may need replacement. My dealer has not reported this issue yet and no recall has been declared for my type of vehicle, but I cannot afford to fix this issue out of pocket and it's a manufacturer issue when making these materials for the car, no fault of the driver. This has now become an issue where my car is constantly leaking coolant and causing potential engine damage.

Turbo coolant lines/ Oil filter housing failed I am reporting failure of the oil filter housing and turbo coolant lines on my 2019 BMW X3. These parts are leaking coolant due to defective plastic components and sealing surfaces, which causes sudden coolant loss and overheating risk while driving. This is a widespread issue affecting many BMW owners and has been documented in forums, service centers, and BMW technical bulletins. The failure poses a safety hazard, including potential engine failure at highway speeds, loss of power, and risk of breakdown or accident. BMW has not issued a recall or warranty extension, and consumers are being forced to pay out of pocket over $3,000 for what appears to be a systemic design flaw in the cooling system.

The radiator hose system has now failed twice due to faulty hoses and connections.
