My car was parked in a shopping center parking lot, as my husband returns to the car after visiting a store, the car had backed reversed unto another vehicle hitting it from behind. This is a safety concern that needs immediate attention as a malfunction is in place. Luckily no pedestrians were walking by. The crash was reported to the police and a report was given. AutoZone's corporate office is to provide video footage of this incident. Currently, my vehicle is sitting in a body shop as advised by my insurance carrier. I do not feel safe driving this car until this is inspected. I will be reporting this as well directly to BMW, as we should not be liable to any damages obtained.

My 2021 BMW X5 M50i experienced a sudden drivetrain failure at approximately 62,000 miles while my children were in the vehicle. There was no dashboard warning light, Check Control message, or advance alert. I noticed serious mechanical symptoms and immediately pulled over rather than continue driving. I am concerned that continuing to drive could have caused further drivetrain damage or created a dangerous situation for my family and other motorists. The dealer inspected the vehicle. In a written diagnosis dated September 15, 2026, the technician identified the front differential pinion bearing as the initial point of failure. He stated that the failed bearing damaged the pinion seal, causing differential fluid loss, and that play in the bearing allowed the driveshaft to contact the oil pan. BMW recommended replacing the front differential and driveshaft and separately recommended oil-pan replacement. When asked about external causes, the technician stated, "No external damage was found." Asked whether similar failures had been seen, he responded, "Yes, we have seen this failure occasionally." I previously reported unusual dragging/jerking behavior to BMW and followed its recommendations involving the transfer case and control/thrust arms. It is unknown whether those earlier symptoms were related. The vehicle received regular BMW maintenance, with no skipped required services. I have also identified multiple public owner reports of front differential failures involving 2021 BMW X5 M50i (G05) vehicles, some at considerably lower mileage. These reports are not independently verified however additional complaints have been filed with NHTSA. I request that NHTSA investigate whether this represents a recurring safety defect, especially given the sudden failure absence of warning and low mileage to have such an instrumental piece of equipment fail. The vehicle was inspected by an authorized BMW dealer; availability of failed parts for inspection is unknown.

POWER TRAIN
Description of Safety Concern: I am writing to formally submit a vehicle safety complaint regarding the xDrive transfer case on my 2021 BMW X5. While driving, the vehicle exhibits noticeable hesitation, shuddering, and jerking during acceleration at lower speeds and when executing tight turns. This erratic power delivery creates a potential safety hazard, particularly when accelerating into traffic, merging onto highways, or pulling out from intersections, as the momentary loss of predictable drivetrain response increases the risk of a collision. Despite internal technical bulletins from the manufacturer (SI B27 02 20) acknowledging shuddering caused by transfer case clutch breakdown, no official safety recall has been issued. I request that NHTSA open an investigation into these xDrive transfer case failures to evaluate the safety risks posed by drivetrain hesitation and potential sudden power loss. Thank you for your attention to this safety issue.

My 2021 BMW X5 xDrive40i intermittently fails to start, occurring on approximately 80% of start attempts, and displays the message "Repeat Start Attempt." This has been confirmed by code reading to be a starter-related malfunction. This defect significantly affects vehicle reliability and raises a potential safety concern. BMW previously recalled vehicles equipped with similar starter motors due to starter solenoid defects that could cause overheating, electrical short circuits, and an increased risk of vehicle fire. The symptoms on my vehicle appear consistent with those associated with the previously identified defect. I respectfully request that NHTSA investigate whether the starter motor defect previously addressed through BMW recalls extends beyond the identified production range, including 2021 model year vehicles. The recurring failure, similarity to previously recalled defects, and potential fire hazard warrants further review.

ELECTRICAL SYSTEM, POWER TRAIN
My 2021 BMW X5 xDrive40i Sport (112,000 miles) intermittently fails to start, occurring on approximately 80% of start attempts, and displays the message "Repeat Start Attempt." The issue first occurred on September 8, 2026, while the vehicle was parked at my residence and was confirmed by BMW Roadshow Memphis on September 11, 2026, as a starter-related malfunction. The dealer quoted more than $1,600 to replace the starter motor because the vehicle is outside the warranty period. This defect significantly affects vehicle reliability and raises a potential safety concern. BMW previously recalled vehicles equipped with similar starter motors due to starter solenoid defects that could cause overheating, electrical short circuits, and an increased risk of vehicle fire. The symptoms on my vehicle appear consistent with those associated with the previously identified defect. Publicly available recall information indicates BMW's corrective action included software modifications intended to reduce current flow through the starter system. However, this appears to be a mitigation measure rather than a correction of the underlying hardware defect. I contacted BMW North America seeking assistance and clarification regarding the similarity between my vehicle's failure and the previously recalled condition. I was informed that my vehicle is not included in the recall population, and no resolution was offered despite my attempts to escalate the issue. I respectfully request that NHTSA investigate whether the starter motor defect previously addressed through BMW recalls extends beyond the identified production range, including 2021 model year vehicles. Specifically, whether these vehicles may contain the same defective components, whether the software remedy addresses the root cause, and whether additional vehicles should be included in an expanded recall. The recurring failure, similarity to previously recalled defects, and potential fire hazard warrant further review to protect ve

The starter motor malfunctioned, which then prevented the car from starting when it was hot. It could only be started after it had completely cooled down. Additionally, the fault code indicated that there was a problem with the starter motor. I also noticed that there was a similar recall before, so I'm wondering if this one might also pose a risk of fire.

ELECTRICAL SYSTEM, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, BACK OVER PREVENTION: WARNINGS
Vehicle: 2021 BMW X5 xDrive40i (G05) Mileage: 54,423 miles Component: Central Information Display (CID)/ MGU (Media Graphics Unit) Head Unit Safety Defect: The CID intermittently goes completely blank without warning. When this occurs, the backup camera is unavailable, creating a safety hazard when reversing. Navigation, radio, Apple CarPlay, and vehicle settings are also unavailable. Failure History/Diagnosis: The first failure occurred about one month ago while I was reversing. After several hard resets and leaving the vehicle unused for two days, the display began working again. The failure occurred again yesterday when my spouse started the vehicle. I took it to Bobby Rahal BMW of South Hills, PA. The BMW technician confirmed that the head unit (MGU) and RAM (Receiver Audio Module) are not communicating. The technician also found corrosion on the head-unit power connector and inside the head unit, suggesting moisture intrusion and/or an internal electrical short. The dealer recommended replacing the head unit, with the part costing over $4,000, plus labor and additional diagnosis to identify the source of the leak/moisture causing the corrosion. Inspection: The defect was inspected and confirmed by the BMW dealer. The failed component is available for inspection upon request. There were no police or insurance inspections. Warning Signs: There were no warning lights or messages before either failure. The display simply went blank. The failure is intermittent and unpredictable. Safety Concern: The CID can suddenly fail during operation, including while reversing, causing loss of the backup camera and other critical functions. Corrosion inside the head unit and on its power connector raises concern about a recurring moisture-intrusion or electrical/design defect. I request that NHTSA investigate whether this is a recurring safety defect affecting BMW X5 G05 vehicles and determine whether a recall or corrective action is warranted.

SERVICE BRAKES, POWER TRAIN, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
We live in [XXX]. We own a 2021 BMW X5-45e. It has about 85,000 miles and has always been serviced by the BMW dealer here in [XXX] – Pierce BMW. On the evening of XXX I drove the vehicle home at 6:30PM after a 30 mile drive and parked the car outside in the shade of our house. The temperature at the time was approx. 95 degrees F. At 6:45PM we left the house and drove on the freeway and city streets of [XXX] about 8-10 miles to see a concert in downtown [XXX]. The temperature at that time was about 90-92 F. There was no wind. We then parked outside the venue for about an hour and watched the concert. We came out of the concert at about 8:30 and started the car. I drove about 200 feet to the corner and stepped on the brake. As the car slowly came to a stop the emergency/parking brake suddenly engaged at about 2-3 miles per hour. The car jerked to a very sudden and violent stop. To get the car going, I had to disengage the parking brake which was on with the indicated brake light. The engine was still on and there were no warning lights flashing. I turned the corner and accelerated again to about 15 miles per hour and touched the brakes to bring the car to a stop. The same thing happened. The car jerked to a sudden stop. To get the car going, I had to disengage the parking brake. The engine was still on and there were no warning lights flashing. It also happened a third time. That time, my elderly wife complained of pain in her back. After the third time, I turned the engine off and waited about one minute. I then restarted the car and drove it home with no problems. We have had no further issues, but this is a big concern as we no longer trust the car to perform as expected. This is a very worrisome issue and would like some answers, but apparently none are forthcoming. I took the car to Pierce BMW and they could find no fault code or problem.

The drivetrain warning light came on shortly after I started the vehicle. I noticed acceleration issues both while driving on side streets and on the freeway. I took the X5 45e into the repair center the day after the notice came on especially given the experience on the freeway, which happened during rush hour traffic. Upon inspection, I was told the starter was beginning to fail and that while there had been a recall on starters on many other BMW models, it did not include the X5 45e. BMW advised I replace the starter immediately due to safety, which cost $2,600. Two weeks later, the same drivetrain light has come on and the X5 is back at the service center for diagnosis.

Water is leaking from the microphone housing directly above the driver’s seat during normal operation. The water drips onto the driver’s head and into the roof‑mounted electronic components. This creates a safety hazard due to potential electrical shorting, distraction while driving, and possible malfunction of overhead electronics. The vehicle has only 63,000 miles, and I purchased the extended warranty. BMW denied warranty coverage and classified the issue as “wear and tear,” despite the fact that water intrusion into interior electronics is a potential design or assembly defect involving the panoramic roof drainage or sealing system. BMW North America told me the dealership would have a 50% goodwill authorization documented for the repair, but the dealership had **no record** of any goodwill coverage when I picked up my vehicle. Additionally, I was charged **$308 for one hour of diagnostic time**, of this issue and this diagnostic fee does **not** apply toward the repair cost. This is concerning and unfair business practice. I have owned multiple vehicles with sunroofs exceeding 150,000 miles and have never experienced water intrusion of any kind. This appears to be a defect that poses a safety risk and may affect other BMW X5 vehicles.

POWER TRAIN, STEERING
I am reporting a front differential/front drive axle failure and a separate steering wheel/steering column adjustment issue. The vehicle was brought to an independent BMW/German repair shop for a routine oil change/inspection. The shop advised me that the front differential/front drive axle assembly had failed or was severely damaged and needed repair/replacement. The vehicle/component is currently at the shop and should be available for inspection upon request. I am concerned this could put my safety and others at risk because the front differential is part of the AWD drivetrain. If it fails further while driving, it could affect drivability, traction, or vehicle control, especially at speed or in poor road conditions. The issue has been confirmed by an independent service center. To my knowledge, it has not yet been inspected by BMW, police, insurance, or government reps. A third-party warranty inspector may inspect it before repair. The exact cause is UNKNOWN. I was told BMW appears aware of this issue because the replacement part has a newer/superseded part number. This suggests BMW may have revised or updated the original part. I do not know if BMW has formally acknowledged a defect, but I am concerned this may be a broader issue given the low mileage. Separately, the power-adjustable steering wheel/steering column sometimes makes a grinding/vibrating noise when I start the vehicle and the wheel automatically moves out/down into the driving position. There were no warning lamps or dashboard messages. The exact date it first appeared is UNKNOWN, but it has occurred more than once. I previously raised this type of issue with a BMW dealer and was told it was a known issue. The exact cause is UNKNOWN. I am concerned it could involve the steering column adjustment mechanism or related components. I am reporting both issues because the vehicle is low mileage and I am concerned they may be safety-related defects rather than isolated maintenance items.

I am having issues with the starter motor / battery. I have read extensively about issues with BMW X5 models having recalls during the production period of my vehicle. BMW is trying to charge $3,000 for a new starter and battery. I feel that this is a known and significant issue with BMW X5 vehicles produced during the same period as my vehicle and would like for this to be covered under recall.

VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM:CONDENSOR/EVAPORATOR
The vehicle's HVAC system failed due to a leaking air conditioning evaporator core. This single component handles both cabin cooling and the windshield defrost/defog function, so its failure compromises a safety-critical visibility system in addition to climate control. The failed component is available for inspection upon request. Safety risk: The vehicle is operated primarily in Florida, where ambient temperatures regularly exceed 95°F and interior cabin temperatures without functioning AC can exceed 130°F. Operating a vehicle in these conditions causes driver fatigue, reduced reaction time, and heat-related illness — all of which compromise safe vehicle operation. Loss of the defrost/defog function also creates a visibility hazard in the humid and rainy conditions common to the region. Vulnerable passengers including children and elderly riders are at additional risk of heat-related illness. Confirmation: The failure was diagnosed and confirmed by an authorized BMW dealer service department as a leaking evaporator core requiring complete dashboard removal to repair, with a quoted repair cost in the multiple thousands of dollars. Inspection: The vehicle has been inspected by the dealer only. It has not been inspected by the manufacturer, police, or insurance representatives. Warning indicators: No warning lamps or dashboard messages appeared prior to the failure. The first symptom was sudden loss of cabin cooling from the AC system. Critical context: This failure occurred at only 12,500 miles on a five-year-old vehicle that has been driven an average of approximately 2,500 miles per year. AC evaporator cores are not wear items and should not fail under any reasonable use conditions at this mileage. This is a widely documented defect pattern affecting 2019–2026 BMW G-series vehicles (X5, X6, X7, and Alpina XB7). Numerous owners across multiple model years have reported identical premature pinhole evaporator leaks at low mileage. The leading technical analysis attri

The vehicle’s rear differential has developed significant internal "play" (excessive clearance between gears). This defect manifests as abnormal vibration and inconsistent power delivery to the wheels. The vehicle was inspected by an authorized BMW Technician at Passport BMW . Although I reported hitting a curb (low-speed impact), the official diagnostic report from the BMW Technician explicitly stated that the curb impact did not cause the differential failure. The technician identified the issue as a failure of the internal differential components, which is consistent with numerous reports of drivetrain defects in the B MW X5. Despite the vehicle being well under the 50,000-mile warranty threshold and the technician’s own finding that external damage was not the cause, BMW is currently refusing to honor the warranty repair for this critical mechanical component. I purchased the vehicle in March 2025 Certified Pre owned.
