I got the dreaded “put car in park and service system now”. I was going about 65 with the A/C on and it was hot for here 82 degrees and humid. I was driving a little more aggressive than normal. But I mean c’mon I’ve got a 4xe. I was able to coast down an exit ramp off the highway as I had no power. I put in park and turned off engine. After the cars behind me were done honking and finally went around me I started it back up and I was able to drive it home normally. I hope this was a one time thing. I wonder if this only happens on the highway. I don’t do highway driving until Friday. I guess I’ll see what happens.
