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.
Mileage: 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.
