“My car completely died while driving it a few months back. Just got it back after about 3 months, partial sucky dealership, partial back order issue. Turns out the sunroof leaked into the dash. Had to replace the body harness and something with the dash. $5100. I estimated on the date it happened because it's been awhile.”

NHTSA complaint #11195519, filed 2019-04, 160,000 miles

“I took my 09 Gmc Acadia to the GM auto to fix the transmission and they told me they can not fix unless I pay the $2043 to fix my power steering, but I believe its all related to that power steering failure that is cover under the GM policy. And its the same problem to all the Acadia that are out there so I suggest the GM to fix all Gmc Acadia without any cost to all the owneri if they fix it right we wouldn't complaint at all”

First that went was the catalytic converters, second my stabliltrak system and traction system said my break was on when it wasn't, thrid was my right rear tire pressure was low and it was not and fourth my battery started going low while driving it.

“The vehicle is equipped with a gear driven power liftgate that opens and closes the rear hatch at the touch of a button. I approached the rear hatch of the Acadia to load groceries, and signaled it to open. The hatch powered open normally to its full height. I walked underneath it. With no warning, the hatch suddenly fell and struck me in the head / back of neck / shoulder area. It hit hard enough to cause serious injury.”
