Hey, Aleigha. I'm noticing the same (I think) on my 2017 GMC Acadia SLT2. My wife's iPHONE Xs works perfectly. My iphone Xr via bluetooth doesn't make phone calls but I'll check when I get in the truck again. Could be my volume is turned down and I can't hear the vehicles phone prompts. I'm going to make an appointment with my dealer soon because I only have one month left in warranty. I know for a fact that my iPhone worked perfectly for several years and just quit working recently.
