2021 BMW X5

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.

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.

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.

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.

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.
