My 2017 volt is now suffering from this issue. The CEL illuminated. It went in to a no start/shift to park until I disconnected/reconnected the battery. Then the display read 1 mile range even with the battery fully charged. Then the reduced propulsion message displayed and the engine started which allowed me to move the car without using the battery. The local dealer looked at my car and referenced the dreaded "18-NA-261" service bulletin and stated the part needed was on "National Allocation".In Chilliwack. Into week 3 of my wait.
Lately, the car has been powering up normally as long as I plug the car in while powered on and power it up before I unplug it. I don't know how long this will last judging by the other posts I have read. The local dealer cleared the DTC codes and printed a diagnostic report for me that shows: "P1E00, U2603-U2624"
The worst issue for me is that none of the local dealers have the equipment needed to remove/replace the hybrid battery. I have to transport the car 150 miles to Mark Wahlberg Chevrolet in Columbus, Ohio to get it replaced. Once the care is there, the whole process starts over. They must read the DTC codes for themselves because they don't trust what the other dealer found. If the car stats normally for them they may refuse to repair it after it travels 150 miles and sits in their lot for a week. If this occurs, then what would I do next?? This system really Stinks!!! GM has abandoned all of us!
