Telematic modular control is not working properly and part is on backorder. Dealership and GMC have refused to put into writing that my vehicle is safe to drive; however, they are refusing rental vehicle while awaiting arrival of part. Several of my safety features are not working correctly, my left turn signal went out randomly and my auto breaking has activated when there has been nothing near my vehicle.
Approximately July 12 2025 while driving to dinner two warnings showed on the driver information cluster (1) check brake assist (2) check esc. Took vehicle to dealer the next business day for diagnosis. Service department stated the problem was the ebcm or electronic brake control module and the parts are on a nationwide backorder. Since the part failure all brake system associated lights on the gauge cluster are illuminated and non of the associated safety systems are functional including but not limited to abs, stabilitrak, lane keep assist, adaptive cruise, crash avoidance or standard cruise control.
