The dealership had to do a spac case in order to get a transfer case for my GMC Terrain, it took 2 weeks for someone to approve it, recieved an email going on 2 weeks ago that the transfer case would be shipped May 4th, then recieved a second email that the part would be shipped the week of May 3rd, just received a third email that says the part will be shipped the week of May 18th. So now due to the horrible customer service, experience and lack of communication I am going on OVER A MONTH now waiting for the part to fix my vehicle.
