I had this happen to me last weekend as well.
It was in the morning after the car had been charging all night. I went to power up and the "reduced performance..." message came up and the miles quickly counted down in red, all the same lights as the above picture - also couldn't put it in drive. Powered down, let the car go to sleep and tried to start it up a 2nd time ... CEL was the only light still on (the error message was gone) but I still couldn't put it in drive (neutral, yes, but no to D or R). So for attempt #3
, I powered down, let it go to sleep and locked the doors and let it sit for about 10 min. Upon power-up, still had the CEL, but now I could put it in drive, etc. So I moved the car out of the garage and proceeded to wash it for a show. Moved it back into the garage after with no problem, just the CEL light still on. Then later drove to the show with the CEL on, no issues other than that (didn't take a scan yet because I couldn't remember the proper sequence of car mode - all teh way on vs accessory?). Had to move the car once after shutting it down at the show and upon this power up, the CEL was gone! So that's 5 total power ups before it went back to normal on its own.
Has anyone had a CEL clear on its own?
Its been fine since then.
