BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
My vehicle offers rear traffic alert system, but it is not working properly. It's a safety issue that I almost caused several accidents because of it. The vehicle is available for inspection. Safety to me and others are at risk because the feature is not working (rear traffic alert system). I have an appointment on May 28, 2026 to have the BMW dealership look into it. There were no warning lamps or messages.

WHEELS
The driver’s side door jamb placard states 35PSI on all 4 tires. The TPMS software states 36 PSI front and 40 PSI rear. Picture of both attached. The manufacture label and TPMS should match, having them conflict is confusing and leaves owner unsure which to follow.

POWER TRAIN
The contact owns a 2021 BMW 540I. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. There was an abnormal sound coming from the vehicle before the vehicle lost motive power. No warning lights were illuminated. The contact stated that the vehicle failed to respond while in drive(D) or reverse(R). The vehicle was towed to the dealer, where it was diagnosed with a driveshaft failure. The contact was informed that the driveshaft needed to be replaced. The vehicle was not repaired. The contact referenced NHTSA Campaign Number: 21V046000 (Power Train); however, the VIN was not associated with the recall. The manufacturer was made aware of the failure. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 66,700.

SERVICE BRAKES
In November 2025 my breaks quit working. I had AAA haul my car to a repair shop. They ran the codes on the car and found that it was related to a recall on 2021 BMW 540i's for the oil vacuum pump assembly, pan and gasket. I then had it towed to BMW and found out that my vin was not in the recall. BMW quoted me $4587 to repair this on a car with 45,000 miles. I then had it towed to a repair shop that replaced the oil vacuum pump assembly, oil pan, gasket and bolts for about $3700. I think that my vin should have been included in the recall. It was a obviously a common problem with my model and I should not have to pay this much on a car with 45,000 miles. I also had to pay $283.81 for BMW to diagnose it.

FUEL/PROPULSION SYSTEM, POWER TRAIN
While turning my 2022 BMW 540i onto a busy, 50 MPH road, the vehicle suffered a catastrophic drivetrain failure, without any physical trauma such as encountering a curb or pothole. The car experienced a total and immediate loss of motive power (propulsion), leaving me coasting in live traffic. This created an extreme safety hazard as I was unable to accelerate or maintain speed to clear the roadway safely. The failure occurred immediately after a significant temperature stress: taken from a heated garage, driven with no issue for 40 minutes, then parked in 15 degree weather for two hours, then complete failure within moments of starting up after the two hour cold parking block. My reading since the incident reveals that BMW quietly switched a critical drivetrain part from a composite/plastic material to metal in later 2022 production runs, due to temperature tress failures precisely as I experienced. This 'silent fix' suggests a known design defect in early 2022 models that poses a recurring risk of sudden propulsion loss. BMW did not do a recall for this, but they should have: I and other drivers were in real danger when my car spontaneously lost all motive ability in high speed traffic.

SERVICE BRAKES
We notice the lose of braking power right after we started the car on 4/30 morning. The car was totally fine before that. took it to the BMW dealer they said the problem is "Vacuum/oil pump failing internally. fault for brake booster pressure switch, no brake boost" I find that there is a recall for the exact problem but it doesn't include my vehicle The "Part 573 Safety Recall Report 21V-598" stated that when It does happen it will cause damage to the oil/vacuum pump. I think recall 21V-598 should include my vehicle

SERVICE BRAKES
I reserved this vehicle with a deposit on Oct. 26. At the time I was told the vehicle was under recall/stop sale for a brake issue and I would not be able to take delivery until the recall work was performed. On 11/5, I was able to purchase the vehicle after the repair work was done. After leaving the dealership, about a half mile down the road I received a message on the vehicle display which said "Brake fluid level low. Have the problem checked by the nearest service center." The message also advised that I could continue driving the vehicle. I returned to the dealership and the car was inspected for roughly 30 mins. The vehicle was released to me and the message was gone. I was advised that the vehicle probably needed brake fluid from the recall repair. On 11/7, while driving I received the same Brake fluid level low message from the vehicle. I contacted the dealership and drove to the dealership to have the vehicle looked at again. About a mile from the dealership, as I applied the brakes, the vehicle suddenly generated a number of messages including "Brake system malfunction, stop carefully. Do not continue driving". At this point the brake pedal fell to the floor. I was able to stop the vehicle by applying a large amount of force to the brake pedal and was able to get to a nearby parking lot. I was very lucky and I would have been unable to prevent a crash under many circumstances. The braking power was almost completely gone from the vehicle. I returned the vehicle to the dealership and they reversed the transaction. From what I read online, the symptoms I experienced were exactly the same as those who experienced the brake failure which led to the recall. This car was either not fixed correctly or (even worse) the BMW remedy for the recall suffers the same potential problem as the original recall. In the second case, I believe this is a very dangerous situation.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
PROBLEM: I recently had several incidents when the RAB (rear automatic brake) on the 2024 BMW 540i vehicle DID NOT WORK on multiple occasions. The vehicle never stopped as I backed out of my parking space. Afterwards I tested the RAB by perpendicularly slowly walking behind the car. I had to run out of the way when the vehicle was continuing to move when approximately 12” from me. I tested both vehicles, 540i & X-3, with the same results. As a further test I placed a plastic figure that’s ordinarily used a warning to drivers of children playing in the area. Results while slowly backing was that the vehicle hit (bumped) the little green “man”. I later discussed this issue with my wife that drives the 2024 X-3. She then informed me that she too almost backed into a pedestrian. I then did the same tests on my wife’s 2024 X-3, VIN [XXX] , with the exact same results. BMW of Wesley Chapel had no solution. I spoke with managers Doonan and Hernandez. I believe the photos demonstrate the slight graze of an item whereby the RAB should have stopped the car; it never should have allowed the collision.

SERVICE BRAKES, STRUCTURE:BODY, VEHICLE SPEED CONTROL
About June 2024 when I was driving downslope at about 30 MPH, when I hit break the car accelerated. Fortunately, nobody and no car were around and I gained control of the car by pumping the break. I did not think much about this issue to report it. On August 23, 2024, I was driving home. I was very close to my home at very low speed (about 1-2 MPH). I hit the break and the car accelerated for the second time crashing into my next door neighbor's house damaging his bushes, steps, spriklers and the gate. My car sustained considerable amount of damages. It was in the BMW Authorized body shop about a month. I received the car on 9/25/2024.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
The rear cross tracking warning system does not provide an audible warning or apply brakes. The settings have been set, and verified with the dealer, including the most sensitive sensor level and loudest audio alert level. I have gone to two different dealers in Ohio and Florida and got the same response, “it works as designed”. My brother in law has a 2023 BMW 440i and has the same issue, with the same results with dealer responses. It’s a well known issue in the BMW community since 2019 models, yet the company doesn’t fix. Not only is it dangerous backing out of parking spaces etc., but it causes a lack of faith in the other critical safety features which you rely on, but cannot easily check; like adaptive cruise and forward collision features.

SERVICE BRAKES
Car did not fully stop when brakes engaged. Caused collision with a wall. Mechanics are currently evaluating the braking system but it appears to be consistent with the brake recall issued for other 2023-4 BMW vehicles—loss of power brake assist or antilock brake to not function properly. (See National Highway Traffic Safety Administration Campaign Number 24V-104 reported on February 12, 2024).

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
On Feb.3, 2023, my wife made a turn into a parking lot. She was driving our 2022 BMW 540. She paused and the engine began to rev up. It then shot forward nearly 50 feet and hurled her over a meridian into another car. She pressed as hard as she could on the brake and suffered a torn meniscus ligament. There were no warning lights and although the car hit front right, no airbags were executed. BMW has not sent an official detailed report from their engineer. BMW advertises brake override so pressing both the brake and accelerator would NOT result in this event.
