Engine And Engine Cooling Problems of BMW X3 - part 2

To whom it may concern, I am submitting this formal safety complaint regarding my 2021 BMW X3, which is currently subject to an active safety recall involving a potential engine starter defect that may result in a vehicle fire. BMW of north America has notified me that water may enter the engine starter, causing corrosion and overheating, which can lead to a fire even when the vehicle is parked and turned off. BMW has advised owners, including myself, to park the vehicle outside and away from structures due to this risk. Since receiving this recall notice, my vehicle has displayed a check engine light, and I have personally experienced a burning or fire-like smell coming from the engine compartment. These symptoms have caused serious concern for my safety and the safety of my child. I contacted BMW regarding this issue and was informed that there is currently no available remedy to repair the defect. Despite the known fire risk and the warning signs my vehicle is exhibiting, BMW has not provided a temporary repair, replacement vehicle, or other permanent solution. This vehicle is my only means of transportation. I am a single mother and rely on this vehicle daily to transport myself and my child to work, school, and essential activities. Being advised to continue driving a vehicle with a known fire hazard, while also being instructed not to park it in my garage, places an unreasonable and unsafe burden on my family. I am not refusing a reasonable solution. I am open to trading my vehicle into a comparable BMW model while maintaining the same existing car note or loan terms. My primary concern is having a safe and reliable vehicle for myself and my child, given the unresolved safety defect and the lack of an available repair. I am submitting this complaint so that the national highway traffic safety administration is aware that consumers are currently operating vehicles with a known fire risk and no available remedy. I respectfully request NHTSA’s review and assistance me .

The starter failed and car would not start, requiring replacement by the BMW dealership. Car is only 4 years old and had 29,699 miles at the time of replacement. Wondering whether noticed starter issues requiring replacement in 2021 BMW X3 m40i models in addition to other 2021 BMW X3 models that have been recalled and required starter/relay replacement.

The car has active air shutters on the grill/radiator, which are known to fail prematurely, causes overheating and emissions issues that trigger a check engine light. This was a know issue that BMW issued service bulletin and a 15 year, 150k mile warranty on the part/component up to 2019 model years. BMW did not resolve this malfunction in the same body style car in 2020, and the issue persists. BMW refuses to cover repairs on this issue that they have previously acknowledged and failed to fix, which effects the safety and drivability of the vehicle. There is a class of owners experiencing this issue who are not covered as a result of BMW failing to take accountability for the design failure in 2020+ model years. Estimated repair costs are $1,600 on average. Previous bulletin: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Reporting a failure of the engine cooling system on my 2019 BMW X3 that developed over time despite repeated repair attempts and ultimately resulted in complete engine failure. Over the past year, the vehicle has experienced ongoing coolant loss and overheating warnings despite multiple coolant-related repairs. When the problem continued, I brought the vehicle to a BMW dealership, where the service department determined that the engine had suffered internal damage consistent with overheating and advised that a full engine replacement was required. These issues occurred during normal driving and created unsafe conditions, including the risk of sudden loss of power or breakdown in traffic. Based on my experience and the repeated nature of the failures despite proper maintenance, it appears that coolant and overheating issues may be persistent in this vehicle model rather than isolated to a single component, and I am concerned that other owners may be experiencing similar safety-related defects. A investigation into this is warranted.

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.

While driving my 2013 BMW X3 xdrive28i under normal conditions, a “drivetrain malfunction” warning suddenly appeared, immediately followed by a “low oil pressure” warning. Within seconds, the engine lost all power and shut off completely while the vehicle was in motion. I had to coast and steer the car off the roadway and push it to safety with the help of others. My safety and the safety of other drivers were at risk due to the sudden and complete loss of propulsion in active traffic. An independent BMW-trained service center confirmed that the engine suffered catastrophic internal damage caused by failure of the timing chain system. This timing chain defect is well documented in BMW’s n20 engines and is the subject of a class action lawsuit. The vehicle is now completely undriveable and remains at the repair facility. Engine replacement is the only option and is estimated between $12,000–$15,000, far exceeding the value of the vehicle. The failed engine and vehicle are available for inspection upon request. The problem has been reproduced and confirmed by an independent BMW specialist. BMW has not yet inspected the vehicle, although I did call and report to BMW north America. They have not responded to my numerous calls and outreach. No police or insurance representatives have inspected it because there was no collision, just sudden engine failure. There were no symptoms before the incident. The drivetrain and oil pressure warnings appeared only moments before the engine shut down. I had no opportunity to safely exit traffic before the vehicle lost power completely. This sudden failure due to a known engine defect presents a significant safety concern.

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.

Unknown . The safety recall is extremely dangerous and I drive my child around. This is unacceptable and very unavoidable by providing a remedy or give me a new car. This is not my fault and my life and my family’s lives are in danger.

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!.

Our vehicle alerted us to over heating and to pull over immediately. Our car then stopped running. We had it towed and was told there was an issue with the water pump sensor and corrosion issues. They alerted us that there was a recall for these issues on our vehicle. We researched and found this to be true. When I contacted BMW they stated our VIN number was not part of the recall but our vehicle match the exact models listed in the recall. We took it to the dealership and they repaired it for $2500 and the reason for the repair was the exact reason for the recall. Spoke with BMW again regarding this and they said if our VIN was not on the recall list there was nothing they could do. I would think when your vehicle make and model matches the recall and the issues are the same you would be part of the recall no matter the VIN number. I would like for this to be reviewed and see if we can get a reimbursement from BMW for the charges we paid out of pocket for an issue that should have been covered by the recall. The recall form attached is one my friend received who has the exact same car we have. The other documents are the service invoice and verification of our payment. Thank you!.

My vehicle is subject to an active safety recall (NHTSA #25v-636) issued in September 2025 involving the engine starter. As of today, no remedy has been provided by the manufacturer. Due to the safety risk associated with this recall, I do not feel safe operating the vehicle and have been forced to keep it parked and unused for an extended period of time. This has caused significant financial hardship, as I am still required to make monthly loan payments, maintain insurance, and cover related expenses for a vehicle that is unsafe to drive. The issue has effectively rendered the vehicle unusable. The manufacturer has failed to provide a repair, replacement, or timeline for resolution. This situation places my safety and the safety of others at risk, as the vehicle may fail to start or function properly without warning. I am requesting immediate action, as this delay is unreasonable and creates both a safety hazard and financial burden.

This recall was in September 2025, and for a starter issue that could cause a fire. Despite the urgency of this recall, it's now six months later, and I am still getting a response from BMW "remedy not available". So, in the meantime BMW advises to keep the car outside in the hot florida sun so it doesn't burn the house down. This is a totally unacceptable situation, and I would appreciate the NHTSA following up with BMW regarding why the delay. It appears to me that BMW is dragging their feet on correcting this serious issue.

While driving, noticed smoke coming from under the hood. Immediately pulled in a parking lot where the smoke turned to fire and burned the entire car by the time fire dept arrived. I was the only person in the car and was luckily able to exit the vehicle before the actual fire started. Incident reported to insurance company and they are investigating. There were no dash warning lights of any kind.

Coolant leak. Oil filter housing coolant leak. Water pump leak. Coolant leaked while driving, and vehicle was not driveable after arriving at the dealership when all the coolant purged out of the vehicle.

See attached document for complaint. It is coming to almost a year that this problem still exists. After multiple attempts to have this rectified still un settled. I tried to make a claim on your website but for some reason the site is not taking my VIN# xxxxxxx, NJ plate tag xxxxxx.

1. The primary failure occurred within the electrical system and engine compartment wiring. According to the official forensic report (ref xxx by the ministry of internal affairs of georgia, the fire originated in the engine compartment due to an electrotechnical fault (short circuit). 2. The vehicle spontaneously exploded and caught fire while parked in a closed, underground parking facility of a commercial building. This created an immediate risk mass casualties due to smoke inhalation and potential structural collapse of the parking ceiling. Fire spreading to dozens of adjacent vehicles. The explosion occurred without any prior warning, posing a lethal threat to anyone nearby. 3. The failure was officially confirmed and documented through a state forensic examination. The ministry of internal affairs’ forensic-criminalistic department conducted a comprehensive technical audit. They ruled out any external factors (arson/accelerants) and confirmed an internal electrical short circuit as the sole cause. 4. Yes. The vehicle was inspected and seized as evidence by the criminal police and the state forensic-criminalistic department of georgia. 5.

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.

One cell in the hybrid battery failed causing the car to go into safety mode. Battery assistance to the engine stopped and gas engine was the only source of power. Was told the car could be a fire hazard in this condition and required repairing the hybrid system.

Light indicator showed low coolant levels. Car was leaking coolant slowly. Filled up coolant but levels continued to go down. Brought to mechanic and they had to remove oil filter housing to replace failing gasket. Car is about 113k miles.

I am unable to drive my 2017 BMW X3 VIN number 5uxwx9c37h0t22306 anymore I recently took my vehicle to a mechanical and they told me that my engine coolant pump is no longer good. I checked for any recalls, and the recall is engine coolant pump which the description explains everything that's happening to my vehicle. This issue has been ruled non fixable, and I will like a responsible solution to this problem.

Engine light diagnostic crankcase ventilation hose defective. There was a recall on this but not for my VIN #, why not I'm having the same issues a described in the recall.

I had my car towed into BMW dealership for a vanos recall repair,it went in for the repair the repair was "done" but before picking it up they told me they were unable to qc/start my engine to verify the repair claiming that because my camshaft position sensor was removed (it was removed to ultimately figure out it was the vanos system that failed)and that my car had no battery at the time of the repair they could and would not start my engine to verify the repair and that they turned it over by hand only,upon them releasing the car back to me I brought a battery and started my car and left the dealership within ten miles my engine failed and locked up due to oil starvation,I had it towed back immediately and explained what happened,and they refuse to take any responsibility for my car failing on the road while driving cause my engine to smoke and push the smoke into the cab mid traffic,this happened in July of 2025 and I am still going back and forth trying to get them to take responsibility and replace my engine,they did not follow proper procedures to ensure my vehicle was safe for pickup violating safety standards.
