NHTSA complaint #11328481, filed 2020-06, 44,000 miles“Multiple occasions when driving vehicle, then attempting to shift from drive to park and actually in park an error comes on 'shift to park' comes on, I've taken it to dealership and they blame me on some light bulbs I changed, well I changed them back and still error occurs. Unfortunately when that happens I can't lock my vehicle for some time until multiple times of turning on and off the vehicle. (2) while driving forward, my rear camera would be displaying live everything behind me, which was very distracting, took it to the dealership, I think they fixed it”
NHTSA complaint #11301684, filed 2020-01, 10,000 miles“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. …”
