Any updates from those who have had this issue? We bought a 2024 2500HD Z71 with the Duramax about one month ago. Today, just over 1400 miles, I was coasting up to a traffic light when I felt a sudden jolt. Immediately had a check engine light, indicator that collision detection was no longer working, check ESC message, check traction control message and reduced acceleration message. I ran the code reader and got the same PO60C code. I find several mentions of this happening in the gasoline versions related to either faulty wiring or lifters. However I don’t see nearly as many for the Duramax.
Did the ECM update seem to fix this issue for you guys? Or have you had recurrent issues? Appreciate any information you can provide.
