Incident: October 27, 2026 · Filed: October 29, 2026

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.

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.

Incident: July 1, 2026 · Filed: September 23, 2026

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.

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.
