NHTSA Complaint #11638552 — 2015 BMW X5

My 2015 X5 decided it was not going to start. The vehicle was was looked at by a technician only to determine thay the cam sensor was not active and the car would not start. Moving forward with diagnostics the sensor was ruled out as good. Moving forward the valve cover was taken off for inspection only to find that the cam side bolt was hanging only by the wall of the valve cover. the gear is still in place it has nkt jumping timing but the end of the cam bolt is and has been broken off at the end inside the man approximately a half inch of the end of the bolt is in the hole. I stopped the technician from moving forward with anything else. I recently looked up for a recall but do not see any for the X5 but open recalls on other models. please let me know if this is a problem with the six cylinder turbo and it under sized cam bolt thank you for your help and time.
