NHTSA Complaint #11469947 — 2018 BUICK ENVISION

On June 4, 2022 the radio bar showed a line in the middle of it and the volume of it would not increase. I could not hear anything. I tried everything even going into systems on the radio. Later that day it corrected itself and went back to normal. On June 18, 2022 the front passenger side window I put down approximately 1-1 1/4” and drove for maybe a half mile then decided to put it back up, it won’t move. I tried from both the drivers door control and passenger door, nothing. I looked in the manual and did what it stated to do, nothing, I got home turned off the car waited, turned the car back on and tried again, nothing. I called the dealership where I purchased the car and to my disappointment no service on Saturday. I have less than 35000 miles on this car no reason why I should be having issues.
