I have had the same problem for 3 years now and have taken my vehicle to a gm dealership many times for the same issue and it is definitely an issue . My car keeps throwing up tcm issue and ecm and I have asked for the modules to be checked. I have reasearched these issues and it seems to be the same with many vehicles like mine so that should be a red flag. My car will slow down, power reduce engine, traction control off, and my steering will be difficult and sometimes I can’t even get off the road in time, which is very dangerous. I have seen recalls on electrical issues and wonder if my vehicle has damaged recall parts. I am a single mother who has to work and get my child to school and can’t do so properly with my vehicle doing this all the time. It’s very frustrating.
