2021 BMW X5 Complaints

POWER TRAIN — Filed 01/05/2024

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.

Problem with starter. They don’t start from first time, sometimes from 2-3. As I’m check it in forums, it can burn another parts and make fire. As i now bmw x5 from 2019 to 2024 have problem with starter and have opened recall for it. But when I’m visit now service center, they say me that my vin number not selected for starter recall and I must contact you first.

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 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.

The contact owns a 2021 BMW X5. The contact stated that the AC was inoperable. The vehicle was taken to a dealer and an independent mechanic on several occasions to repair the AC; however, the failure reoccurred after each repair. The AC was not replaced. The contact believed that the issue was caused by Hybrid system.

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 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.

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.

BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE — Filed 12/21/2023

On Wednesday, December 20, 2023, shortly after 8:30 p.m., I turned into the driveway for my Columbia residence and proceeded with caution toward my carport. The weather was clear, with no rain or ice, and my driveway was free of all obstacles. My 2021 BMW X5 began to accelerate and move forward at a dangerous speed. Though I applied the brakes, they were unresponsive, and the vehicle collided, with force, into the brick steps at the carport entrance to my home. Upon impact, all airbags in the vehicle deployed, and the emergency response system was activated. Prior to impact, none of the vehicle’s safety monitoring features responded. These would include the system by which the vehicle’s speed is regulated whenever a vehicle on the roadway, in front of the X5, slows down or brakes. Neither did the warning system activate – the system that monitors the presence of obstacles in front of or behind the X5. The 2021 BMW X5 sustained significant front-end damage in the collision, and my residence was also damaged by the vehicle. I deny that the incident was operator error and believe it to have been the result of a vehicle or computer malfunction. Interestingly enough, the X5 had been serviced by BMW of Columbia on Tuesday, December 12, 2023. That routine service included a brake flush.

2021 X5 M50i: The driver's knee airbag deployed in a crash and lacerated my left lower leg down to the muscle and abraded most of the layers of skin on my right shin. I was taken to the ER by ambulance. The laceration could only be partially sutured together. There was no shrapnel in the wounds. I have to go to a wound care center to treat the mentioned injuries. Everything else on me was fine, just some bruises and sore muscles; my car saved my life. I was not at fault. All airbags, except the vacant front passenger, were deployed. I was the only occupant of the vehicle. The airbags have not been inspected by the dealer or anyone else as it was a total loss and taken away to a salvage lot to be sold at auction. The insurance company went by the photos that I sent in. I have a lot of photos. There are knee airbag recalls on other model years of this vehicle but none on mine, the subject VIN. It has had no recalls since I owned it and I bought it new in Sept 2020. There were no warning indicators of any potential problems prior to the crash. I suspect the edges may be sharp or it didn't deploy properly. I hope these airbags can be checked to see if they are defective as they can really hurt someone. (There is a lot of insurance claim communications that I haven't attached but I will if requested)

The contact owned a 2021 BMW X5. The contact stated that while sitting in the vehicle and with the vehicle running, it suddenly accelerated on its own. As a result, the vehicle jolted into traffic and collided first with a bicyclist before continuing on to collide with the rear of another vehicle. The bicyclist sustained minor injuries. A pedestrian later reported that they were also struck by the vehicle, but the contact stated that she was skeptical of the validity of their claim. The air bags did deploy. A police report was filed, and injuries were reported. The driver and passenger were both treated on scene by EMS and later evaluated at an area hospital for injuries resulting from air bag deployment. The bicyclist and a pedestrian were both treated at an area hospital for unknown injuries. No warning lights were illuminated. The vehicle was towed to a tow yard and declared a total loss. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 36,000.

Previously reported that the BMW X5e, Plug in hybrid, shuts itself off once the driver's door is opened leaving anybody in the car at risk of serious health problems or even death! A menu selection option should disable this unsafe practice but it does not work. As if there is a software glitch. Other models, the X3e stays on when the driver's door is opened. I've previously reported this item but now my father has injured himself recently. After a medical appointment and retrieving his medications my father was in the car in unsafe and deadly heat and attempted to exit the vehicle due to the car shutting itself off and he fell and hurt himself. The manufacturer has been contacted several times and at times they say this should not be happening but the dealers are saying that is how the vehicle is designed. I also have videos of the other models not shutting off for review. PLEASE FIX THIS ITEM!

The cars hybrid batteries caught fire while sitting in garage being charged. After car was removed from garage and fire department had things "under control" which took about 2 hours they left saying it would be towed in the morning. About 30 minutes later the car exploded setting fire to the house. The house was saved the car is nothing more than a burnt shell, a total loss. Thank God no one was hurt but I see where BMW had a ton of recalls on the 2020 version on the exact version of this vehicle for the same thing. Obviously nothing was fixed.

THIS IS A NEW BMW X5 2 MONTHS OLD WITH 2000 MILES. THE VEHICLE WAS PARKED NOT RUNNING WITH NO POWER IN MY GARAGE. ON SATURDAY MORNING IT SPONTANEOUSLY COMBUSTED INTO FLAMES. I HAPPENED TO BE NEAR THE GARAGE AND SPOTTED THE FLAMES 4-5 FEET TALL SHOOTING OUT FROM HOOD. I IMMEDIATELY RAN INSIDE TO ENSURE MY FAMILY WAS EXITING THE HOUSE AND WE CALLED 911. I ATTEMPTED TO EXTINGUISH THE FLAMES WITH A HOSE WHILE WAITING ON THE FIRE DEPT. THEY ARRIVED AND EXTINGUISHED AND CUT ALL ELECTRICAL POWER TO THE VEHICLE AND WINCHED IT OUT OF MY GARAGE. VERY UPSETTING AND DISTURBING THAT THE NEW VEHICLE RANDOMLY BURST INTO FLAMES WHILE SITTING IN GARAGE.
