2021 BMW X5 Problems

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.

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 contact owns a 2021 BMW X5. The contact stated that the vehicle failed to immediately start. The vehicle started later. The engine and a yellow warning light flashed on the instrument panel. Upon research, the contact located the German Federal Motor Transport Authority (Kraftfahrt-Bundesamt), for KBA Reference Number: 16131R, which was associated with the starter motor. The contact stated that the failure was associated with NHTSA Campaign Number: 24V576000 (Electrical System, Engine and Engine Cooling) and 25V644000 (Electrical System). The vehicle was taken to an independent mechanic who determined that the failure was associated with the starter motor, which was replaced. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, and the contact was informed that there was no recall on the VIN associated with the failure. The failure mileage was approximately 49,000.

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.

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 contact owns a 2021 BMW X5. The contact stated that while driving at an undisclosed speed, the air bag warning light unexpectedly illuminated. The vehicle was taken to the dealer where it was diagnosed that the air bag had failed and that the air bag and/or the sensor needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA hotline for further assistance. The failure mileage was approximately 63,382.

Described by BMW as a "malfunctioning passenger restraint system", the sensor detecting weight in the seats is faulty without any external factors. The safety of both minors and adults is placed at risk when a system like this malfunctions, either keeping the airbag on or off. The automatically-adjusting seatbelt is also affected by this. There was a warning message for this displayed.

Formally reporting a serious and recurring safety issue with my 2021 BMW X5. Over the past five months, I experienced three separate incidents where the vehicle abruptly stopped while driving, each time displaying a red car warning light on the dashboard. The red malfunction symbol was similar to the below image (found online) Description of the Issue: Each of these terrifying safety experiences occurred while the vehicle was in motion—all on surface streets—the car suddenly came to a jarring and immediate stop on its own without my input or applying the brakes. There were no cars close to or in front of me or debris in the road that would require the car to stop to avoid impact. The red car icon appeared on the dashboard (commonly associated with collision warning or automatic emergency braking systems). The abrupt stop caused my seatbelt to constrict, jarring of my neck and ongoing concern that it will happen again. Thankfully, no accident occurred, but the abrupt stops could have easily caused a serious or fatal accident, especially under highway conditions. My Concerns: This represents a serious safety hazard not only to me and my passengers but to other drivers on the road. The issue appears to be a malfunction in the automated safety or integrated systems, possibly involving the forward collision warning or automatic emergency braking systems. My local BMW dealership (Gwinnett Place BMW) has given me an estimate of $480 to perform 2 hours of scans/diagnostics to inspect the vehicle. No loaner car or transportation offered. This is a known issue and documented in online forums and comments. I have lost confidence and trust in my vehicle and feel unsafe. For a $70k automobile that should not be the case. Requested Action: I am requesting BMW investigate this matter urgently, outline next steps at no charge since multiple reports exist of similar incidents, and provide a clear resolution, including any necessary recalls

In a parking garage I found a open space and slowly moving towards that to park, car was approaching space at about 10 ft from that, all of a sudden car accelerated and lurched forward and hit the parking structure wall. Airbags deployed for all three of us, one of my colleagues was in passenger seat, another in the back seat. There was no warning on no time to react, this happens in seconds.

Car was parked in fairly level spot with engine off, gear selector in park position, , key fob not near vehicle. Approx 30 minutes later, I returned to find vehicle approx 30 feet behind parking spot, having apparently drifted into another car in parking lot. No idea how car moved. I believe some electronic release of parking selector allowed car to roll.

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

I was driving and I heard a huge explosion so I pulled over and found that the panoramic sunroof had exploded.

Unintended acceleration when slowing to a stop. Car accelerated requiring significant brake pressure to avoid hitting the stopped car ahead. This has happened on two separate occasions. Checked to see if carpet or any other physical interference could have caused the issue. No issues found. Cruise control was lot activated and incident was a low speed.

DROVE AT THE SPEED OF 75 MPH IN THE HIGHWAY ALL IN A SUDDEN THE CAR LOST POWER UNTIL ITS SPEED DROPPED TO 62 MPH. IT IS A HYBRID. DASH BOARD SHOWED SOME RESERVED BATTERY POWER AND HALF TANK OF GASOLINE. IT IS A BIG SAFETY ISSUE. NEED TO FIND THE CAUSE OF IT.

UNKNOWN

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.

Steering the vehicle in a low gear causes the vehicle to tremble or shudder. The dealership identified the problem to be the transfer case fluid. In manufacturing, BMW put a fluid which did not meet the specifications of the vehicle. The transfer case fluid is documented in the manual of BMW X5 M50i (2021) to be something which does not require replacement in the lifetime of the vehicle. I raised this issue when the vehicle was under warranty, but the dealership ignored the issue. After the warranty period was over (62,000 miles), the dealer recommended that I replace the fluid to fix the shudder issue. It is a very well known issue, and there is a service bulletin issued to the dealerships to deal with this particular case (SIB 27 02 20). After the fluid replacement, the issue went away. This issue is widely known by the dealership, and it is a safety issue. I had to pay for the fluid replacement, and I believe BMW should have recalled this issue to replace the fluid for ALL X5s manufactured in 2020 and 2021. This is a safety issue.

The front driveshaft universal joint failed causing the drive shaft to bust a hole in the engine and crack the transmission. There was no knocking noise prior to failure. It suddenly failed, disengaged and caused damage. I was told by service manager the u-bolt must have been defective to have failed without warning.

In the middle of driving, multiple warning lights came on in the car and the steering became very stiff, which made it difficult to steer the car. We brought the car to the dealer service station and they identified that the crank pulley system had a failure and the vibration damper needed to be replaced. Apparently, this issue also resulted in the engine not properly charging the car battery, which also resulted in battery failure. This car only has about 38,000 miles on it and has been plagued by safety issues. The difficulty steering the car could have resulted in an accident on the road. This same car also had a water pump failure at approximately 35-36k miles that was separately reported to NHTSA previously.

The low beam headlights do not illuminate the road sufficiently when there are dips in the road or going up hill. The dealer says the lights are fine but relative to the other cars, there is clearly a problem with low beams on undulating roads. On undulating roads or going up hills, the low beams often only illuminate about 20 ft in front of the car. The problem appears to be BMW has drastically limited the upward lighting from the lights for safety of other drivers. However, they have gone too far and created a safety issue with too little upward illumination to be safe on uneven roads. The low beams are great on a perfectly flat surface, but even with a small up hill grade, the low beams are not set to provide enough lighting of the road. I have taken to driving with high beams on for undulating roads because of the lighting provided by the low beams is so bad. This means inadvertently blinding oncoming drivers because I don't turn the high beam headlights down soon enough. I often need to use high beams to read the names of side street signs. The turn signal does a better job illuminating these side street signs than the low beams. By trying to enhance safety for on coming drivers from low beams, they forgot to account for real world driving condition of undulating roads and have created a worse safety issue by forcing more frequent use of high beams that absolutely blind on coming divers.
