Stopped by the local Walmart last night for a DCFC charge, on the way home the engine light came up. Ran the codes and showed up as P1E00. I searched online and the forum and found a few posts about it, but nothing concrete with respect to the Spark. OBDII scanner says it is related to the HPCM2. Was able to drive home and to work today with no problems. Last time I did a fast charge was about 5 days ago and no issues then.
Scheduled to drop off the EV on Friday. It's the 2015 model with 27k miles, so it should be under warranty. Anyone with similar issues before? I'll post updates once I hear back from Chevy.
