Engine And Engine Cooling Problems of BMW X3 - part 1

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.

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.

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

A BMW dealership has indicated that the motor mounts on my vehicle need to be replaced. My vehicle has under 29,000 miles, and these parts are designed to last for 60,000 to 100,000 miles. A premature collapse of the motor mounts indicates a manufacturing defect, material weakness or installation error from the factory. I understand that this defect is common for 2018-2020 X3 models. The vehicle did not display any symptoms of this defect and no indicators were displayed on the on-screen monitor.

Beginning oct 1, 2025. The cars drivetrain warning came on intermittently until mechanics correctly diagnosed the issue. Thermostat valve failed to shut off properly causing the car to overheat. This has been an issue and recall already, just did not include my VIN. Now it has happened to me at the cost of 2k and under 45k miles. Heat management module had to be replaced due to the danger of overheating and complete car shut down. I am turning this into BMW as well.

I own a 2013 BMW X3 equipped with the n20 engine. After approximately 17 months of ownership and only around 11,000 miles of normal driving, the vehicle suffered a sudden and complete engine failure without warning. The independent diagnostic determined the failure was due to a timing chain and oil pump drive chain defect, which is a well-documented issue in BMW n20 engines. This defect has been acknowledged by BMW through technical service bulletin si b11 03 17 and the national class action settlement bang v. BMW of north America. The defect causes premature wear and eventual breakage of the timing chain components, resulting in catastrophic engine damage. My vehicle is now inoperable, and the cost to repair exceeds $7,500 — far more than the vehicle’s value. There were no prior warning lights, noises, or messages. This sudden engine failure creates a safety risk, as the vehicle could lose power unexpectedly while driving. No authorized BMW dealer had ever performed timing chain replacement on this vehicle, and the issue was not disclosed at the time of sale. I am filing this complaint so NHTSA is aware of the widespread nature and serious safety implications of this defect.

Engine over heating alert issued and to pull over immediately. We had car towed to BMW dealership who stated it is water pump issue. This is a known issue for this make and model but recall not in effect for our VIN. We are having the same issues as stated in recall for water pumps and temperature control issues. Just because our VIN number is not associated with this recall they will not repair this issue unless we pay out of pocket. This is a known issue for our make and model of car and should be a covered expense by BMW. I have attached a link to the recall issues. Please review and respond accordingly. Thank you!.

2019 BMW X3 VIN # 5uxtr7c53klr50002 odometer - 70,000 miles dealer - united BMW, 11458 alpharetta hwy, roswell GA 30075 I purchased my 2019 BMW X3 from united BMW in October 2022. The car had a little over 22k miles at the time or purchase. My vehicle suffered catastrophic engine failure on August 2, 2025, just 48 hours after a BMW service technician topped off coolant in response to a warning light. The vehicle has been properly maintained, including repairs from united bwm service and a BMW certified independent mechanic. The engine failure occurred under normal driving conditions, rendering the engine inoperable. I have received a full diagnostic from BMW and they acknowledged that the independent mechanic was not at fault. Previous contact with BMW consumer relations and the united BMW service manager has not resolved the issue. The repair estimate from united is $40,000. Since I purchased my vehicle from united, they offered to reduce my repair cost to $33,000. I still owe $25,000 on this vehicle. Given the sudden failure shortly after BMW's service, this appears to be a serious reliability and potential safety defect. I have copies of my service records. Kindly advise.

On 7/3/25 took 2019 BMW X3 in for service & received a call that the engine mounts had collapsed and the repair would be $2,098. 50 and to me a car with only 68k miles should not have this issue - first time in any car I've owned. The service advisor, sheri holtz of century BMW, 2934 laurens road, greenville SC informed us that this was a common issue but no recall currently. Went on to research and youtube had information that this is a known issue and one of the top 10 problems with the BMW X3. Contacted BMW client care to seek reimbursement and claim was denied. Also sent a letter to BMW customer relations and no response. A 6 year old car should not have motor mounts collapsing and this is obviously an issue with BMW. Most consumers do not know how to report this complaint but if there is a way for you to search BMW dealers for how often this repair is happening, you will most likely find this is an issue.

Subject: rear differential mount failure and driveshaft breakage — sudden loss of vehicle control at highway speed complaint summary: while driving at highway speed, I experienced a sudden and extremely loud bang from the rear of the vehicle. Immediately afterward, I lost complete control of the rear end, accompanied by violent clanking and grinding noises from the driveline area. The gearbox then stalled, leaving the vehicle disabled in the middle of the highway. Upon inspection, it was determined that a rear differential mounting bolt had sheared, causing the differential to shift violently out of position. This sudden movement resulted in the driveshaft breaking, which further destabilized the vehicle and led to a severe and immediate loss of control. This failure occurred without warning and created an extremely dangerous situation. The sudden loss of drivetrain integrity at highway speed placed both myself and nearby motorists at serious risk of a crash. A component as critical as a differential mount or driveshaft should not fail under normal operating conditions. This incident strongly indicates a serious design or manufacturing defect affecting the vehicle’s powertrain and structural safety. Requested action: I urge the NHTSA to investigate rear differential mounting and driveshaft failures on this vehicle model. Such failures can lead to catastrophic loss of control, and immediate attention is necessary to prevent future incidents and ensure driver safety.

Coolant is leaking and empty every week. Engine overheating warnings! I purchased this vehicle used on [xxx] from autofair in manchester nh 1 week after purchase coolant warnings and engine light came on.

On April 26, 2025, while driving my 2022 BMW X3, the vehicle suddenly emitted smoke and caught fire. Fortunately, all five passengers, including myself, were able to exit the car before it became fully engulfed in flames. The car was destroyed and is a total loss. The BMW app later displayed a “drivetrain malfunction” message, which did not appear until after the fire had already started. The vehicle was still under the manufacturer’s 48-month new vehicle warranty and had no open recalls at the time. Routine maintenance and service had been performed at authorized BMW dealerships. I am concerned this fire may have resulted from a manufacturing defect, especially in light of similar reports and recalls involving fuel rail cracks or leakage in this model/year. No injuries were sustained, but this was a terrifying and traumatic incident, and I am now left with significant financial loss. What I am requesting: I ask that NHTSA investigate whether this fire was caused by a manufacturing defect common to the 2022 BMW X3 and whether a broader recall or corrective action is warranted.

I am reporting an unresolved safety recall (NHTSA recall number: 25v202) on my 2025 BMW X3 (VIN: [xxx] ). The recall is related to a defect in the electrical connection between the starter-generator and the positive battery cable. This could lead to engine stalling while driving, or in extreme cases, a fire due to overheating and smoldering. The defect creates a serious safety risk to both driver and passengers. I purchased this vehicle under financing, and I am still making monthly payments while being unable to safely use it. There is currently no remedy available, and BMW has not provided a timeline or solution. I am afraid to drive this car due to the potential danger. I am requesting urgent action from NHTSA to escalate the resolution of this safety issue. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
