We have a 2020 Telluride EX with 53K miles. Wife was driving to work and the mirror blind spot indicators started blinking, every warning light on the dash board came on, shift indicator lights out, speedometer not working, digital nor analog, tachometer not working, temp gauge pegged out on Hot, power steering seems to be inoperable as well. I'm sure I forgot a few things. At the dealership now, they have no clue as to what the issue is yet. Anyone else have this happen?? Ideas?? Thanks
