Bruce Nunnally Posted July 28, 2021 Report Share Posted July 28, 2021 Got a check engine light with a couple of codes. Took it in to dealer, and they found the wiring hardness had a defect. They are covering it under the powertrain warranty. Apparently they do see this now and then and it is just situational -- it can mean low transmission fluid, bad sensor, bad harness, etc. Quote Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
