“My 2018 Gmc Acadia slt-1 has been having acceleration issues like shuddering and or feels like a full loss of power , with no check engine light. I've taken it into the dealership twice for this problem . I've only taken it in this 2nd time because it got worse and scared me that it would die on the highway. It also has had to have the battery charged 3 times in a couple of weeks , yet the dealer says the battery checks good. At the least I believed since its under warranty they would change the battery in the case the computer is causing issues based on battery voltage. …”
