This is my concern as well. When we got back from vacation, my battery had completely drained, which I was able to jumpstart without issue. However, I had check engine, loss of all ECS and ABS, truck governed to 62 mph max, it was the most horrific 25 mile drive I have ever had, well, since the early 1980’s that is lol. Makes me wonder about the quality of these trucks, now built south of the boarder. Guessing the quality is suffering, but the profits for GM are not. Pretty scary.
