2018 XT5 Platinum, 2016 CTS-V
We just picked up my wife's new 2015i ESV a week and a half ago. Have 650 miles on her and no problems until today. When my wife stated the car to come home from work this afternoon (3rd start of the day), the Big bright collision warning popped up in the HUD briefly. It drives fine, everything works great and no other warnings anywhere. It has done this on repeated start ups since then. It had never happened before today. Is this a normal warning message popup, or is something potentially wrong? Anyone else have this happen to them? It has been raining on and off today, so I don't know if it is a sensor isssue. Thanks in advance.
