in the 2019 GMC Canyon, when I shut the engine off, does all power go off?

What is your question?

We have had our Canyon into the dealer five times because of a dead battery. We bought the Canyon new and have less than 3,000 miles on it. Every time the dealer tells us, nothing is wrong. We bring it home, drive it, and in a few weeks/months it refuses to start and we have to have AAA jump start it, so we can take it to the dealer. When I shut the engine off does all power end? In other words, does the radio, heated seat, or anything stay on and drain the battery? No noises or leaks. Just a dead battery. I have all the paper work from the dealer, if you would like a copy.

What makes this problem better or worse?

Nothing. It just happens unexpectedly.

How long has your 2019 GMC Canyon had this problem?

Every since we bought it brand new.
