Automatic Emergency Braking problems of the 2024 Volkswagen Tiguan

The defect has occurred since the day the vehicle was leased. The entire multimedia and safety interface shuts down randomly while driving (screen goes black, gps stops, rear camera and driver-assistance functions stop working). This happens in multiple areas across the city, not in a single location. The dealership initially blamed my internet or phone, delaying proper diagnosis. The first available service appointment was more than a month later, and the vehicle was first taken in on January 27, 2025. Since then, the vehicle has been in the shop more than five times across multiple dealerships, including over a month during the most recent repair attempt. I have also been required to visit the dealership more than 30 times for the same issue. Dealership technicians and the service manager stated that the vehicle is defective, that nothing else can be done, and that all repair attempts have failed. The manufacturer claims it is an “environmental connectivity issue” in one spot, which is not accurate. Multiple videos requested and submitted show the failure happening in different areas of the city. At the dealership’s request, I drove with a technician who recorded the failure again. Customer care instructed me to return the loaner vehicle immediately and take back the defective vehicle, even though it is unsafe to operate. The customer care manager refused to speak with me and required an appointment several days later, but they still demanded that I return the loaner and pick up the unsafe vehicle now. When I requested written documentation acknowledging that the vehicle is unsafe, they refused to provide it. This is an unresolved, repeated safety defect that puts me at risk while driving. Please, I'll appreciate any help. Thank you in advance.
