10/2020 Ram 2500, 6K miles. Towing 8K down hiway, cruise set to 72mph, smooth road, tow/haul mode engaged, exhaust brake set to auto. All of sudden it was like the ignition switch was turned off and back on real quick. Cruise control dropped off, tow/haul mode and exhaust brake modes dropped off, alternator stopped charging (voltage went to 12.5 then started climbing again to 13.8), throttle was momentarily unresponsive. Then all back to normal with an flashing ETC (red lightning bolt) on. Upon shutdown and restart, ETC was on solid (red lightning bolt). Dealer said updated ECM software, and cleared code. Now happened again, same exact circumstance. Any others have this??
