My vehicle is subject to an active safety recall (the federal safety agency #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.
2021 BMW X3 engine complaints

I'm reporting a safety issue with BMW vehicles equipped with the B58TU engine, primarily 2019-2021 models. These vehicles have an oil pump with an internal plastic component that regulates oil pressure, and this part is fracturing in the field, causing sudden loss of oil pressure. The failure typically occurs during cold starts in low temperatures. When it fails, oil pressure becomes erratic or is lost entirely, often with little to no warning before engine damage or vehicle disablement. Warning signs, when present, include inability to measure oil level electronically, abnormal oil pressure, or sudden drivetrain malfunction warnings. These can rapidly progress to engine shutdown or severe damage from oil starvation. This creates a dangerous situation because the vehicle can become disabled without warning while driving or after startup. This is especially hazardous when cars become immobilized in traffic or during winter conditions when failures occur most frequently, leaving occupants exposed to freezing temperatures while awaiting assistance. Pump replacement requires extensive disassembly and commonly costs $6,000-$8,000, assuming no engine damage. A critical concern: owners cannot determine if their vehicle has the original plastic pump or the later metal revision. BMW's VIN-based parts lookup now shows updated components even when original plastic parts remain installed, and BMW has removed the original plastic part number from dealer networks entirely. Failures are reported across multiple production years, and the scope of affected vehicles remains unclear. Because this condition causes sudden vehicle disablement without adequate warning, especially in cold weather, I believe this warrants investigation as a potential safety-related defect.
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 federal safety agency is aware that consumers are currently operating vehicles with a known fire risk and no available remedy. I respectfully request the federal safety agency’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.
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.
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.
The contact owns a 2021 BMW X3. The contact stated that while reversing, the vehicle lost motive power. The check engine warning light was illuminated. The vehicle had decelerated and was jerking abnormally. There was an abnormal flickering sound coming from the vehicle. The vehicle was taken to an independent mechanic who retrieved codes related to computer failure. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 101,000.
BMW b58 engines have been having issues with oil pumps, common symptoms are the oil level not being able complete above 20%. Which indicates a failing oil pump upon a lot of research it’s a very common issue b58 owners know about, many report having seized engines, low oil pressure warning lights. Lots of complaints have been opened with bmw, with bmws response being to replace oil pump. I have this issue on my car and now have to look into getting the oil pump replaced
The car has keyless ignition and was accidentally left on/idling in the garage despite no one in the car and the key fob not present. The car was on for 8.5 hours in the closed garage and filled the house with exhaust, which includes dangerous carbon monoxide fumes, known to be lethal and nearly ended in tragedy. Luckily, my wife woke up for an unrelated reason to check on our daughter and smelled the fumes in the house and found the car running in the garage. Multiple carbon monoxide detectors were in the home and did not go off, so presumably the fumes had not yet reached toxic concentrations by the time the car was turned off. 2 days later, I took the car to the BMW dealership to be inspected for defects and was told by the technician that it was functioning properly and I should assume the engine is running if the keyless ignition button is not turned off. The lack of an auto-shutoff safety feature to prevent this occurrence is completely unsafe and unacceptable. This is a known issue of keyless ignition cars for over a decade and is an easy mistake to make given how quietly the cars run. Many other car manufacturers have already implemented this feature, so it was shocking that such a well-respected car brand like BMW did not include this safety control as a default feature.
I was slowly pulling into a parking space and as I applied pressure to the brakes, there was no response. In fact the car seemed to rev up and accelerate, jumping the curb and ramming a tree. I was able to steer away from the tree to avoid hitting the center of the front end, but smashing the left front. Even after hitting the tree the car did not slow and I’m trying to pump the brakes, there was no response… I kept going over a grassy area, across a sidewalk and back into the driveway in front of the building, finally the brakes engaged and the car came to a stop. I was then able to pull into another space safely out of the way. I was so lucky it was only 7:15 am and no pedestrians were around and no other vehicles. So I did not hit anyone and did not injure myself.
Intermittent Check Engine Light with the Plug In Hybrid X3 30e since January 2023. Vehicle has been taken back to BMW 2 times and released back to me without permanent fix. Vehicle as of April 2023 is currently held at dealership for 3rd time still without fix. Each check engine light results in a trip back to the dealership service center because we wouldn't know what is the severity of the issue. My safety is put at risk because a normal drive suddenly becomes worrisome and interrupted at random times and we have to attempt to safely pull over to call roadside assistance. Currently in communication with local dealership and have reached out to BMW Customer Relations without response yet.
The check engine light is on. We have taken the vehicle to 2 different BMW dealerships and the problem persists. I have contacted BMW of North America and they have not responded. We are hesitant to drive this vehicle since it is unknown why the "check engine" light is on. Thank you.
The high voltage battery recall has been open for 1 year, which any reasonable person would agree is far in excess of a reasonable amount of time as the issue is one that could lead to a fire / death.
I was at a stop light and when the light changed I stepped on the gas. The car suddenly turned completely off. I had no steering, no braking no ability to turn the hazard lights on. I was in the middle of the street with traffic behind me and my child was in the back seat with me. The car completely died. There were no warning signs at all Cars started to go around me and I exited the car with my child to avoid getting hit because I could not put my hazard lights. I called my husband and after about 10 minutes I could see the headlights were on. My husband gave me his care and he took my car home but he said the car was acting weird and kept shutting off while on the way back home. then it shut off completely again in our driveway and we cannot close the doors. We are waiting for BMW to pick up the car tomorrow.
