Adaptive Cruise Control problems of the 2022 Cadillac Escalade

At the end of 2024, the gps, onstar, and telematics system in my vehicle stopped working completely. This failure disabled critical features including navigation, emergency support (onstar), and super cruise. I was living in California at the time and contacted local service providers, but was told the necessary mobile phone control module was unavailable. After relocating to texas, I took the vehicle to covert Cadillac in austin. The dealership confirmed the issue and ordered the part, but after several months and multiple follow-ups, the part has still not arrived. As of June 2025, the vehicle remains unrepaired, and I continue to drive without gps or emergency support. The dashboard displays a constant gps error. This issue, now lasting over 6 months, puts my safety and the safety of my passengers at risk—especially during long-distance travel and unfamiliar routes. The dealership has acknowledged the problem but cannot resolve it due to ongoing parts unavailability and lack of response from the manufacturer. This is a serious and unresolved safety defect. I am requesting an immediate investigation into gm/Cadillac's failure to provide timely service, support, or resolution for a vehicle-dependent safety system.

The vehicle acts like it wants to cut off, and when the lane driving assistance option is activated, it will jump lanes and almost cause an accident.
