NHTSA complaint #11728855

Owner complaint summary

My 2024 BMW X5 experienced a complete megatronics failure at 54,500 miles. The megatronics unit controls critical vehicle functions including transmission and engine management. This failure caused the vehicle to become completely inoperable — posing a significant safety risk. This failure occurred just 4,500 miles beyond the factory warranty on a barely 2 year old vehicle. A 2024 model year vehicle should not experience such a critical safety-related failure at this mileage. BMW Corporate has been unresponsive for 7 days despite opening case number XXX and promising a 3-5 business day response. I am requesting NHTSA investigate whether this is a widespread defect that may affect other 2024 BMW X5 owners. Incident Description: "Vehicle suddenly entered limp mode while driving at highway speed on XXX in [XXX] . This caused an unexpected and dangerous loss of power while surrounded by highway traffic creating a significant safety hazard. Vehicle was unable to maintain highway speeds and had to be carefully maneuvered to the shoulder of the road. Vehicle was subsequently driven to BMW Dealership in [XXX] where it was diagnosed with a complete megatronics failure."
