ccm CCM and BCM issues
All Terrain Sierra posted a topic in 2014-2018 Silverado & Sierra Troubleshooting
I just had the CCM and BCM replaced on my 2018 Sierra, 1500. 10,000 easy miles. Freak thing, traveling on the interstate, gauges started flipping back and forth, forward drive went out, all alarm messages on the dash: trailer brake, emergency brake, etc. Turned truck off, waited 10 minutes, restarted and could limp off the interstate, with very limited drive train, to a truck stop. Engine would start and run and this went on for a couple hours. Finally the truck would not start, battery was fine. Needed a tow to get it back to the dealership. BCM was very difficult to get, took about 2 weeks. Truck was out of service for 18 days. Cautiously optimistic it's okay now. Anyone have a similar experience?-
