So it was raining a little and I was sitting at a light for like 2 mins and I noticed the car moved or jerked a little twice and then when the light turned green my car wouldn't go. I noticed it slowly rolling backward as if it was in neutral, so I put it in park and put my hazards on, then turned off the car and turned it back on and it worked, but now im a little freaked out and don't want it to happen again. One or 2 days earlier I got a warning that said electrical system failure, but it went off a few miles later, so I checked for codes and had 3 all of which sounded like minor things, nothing that would cause my car to do this. Does nyone have any ideas to what may be the problem? I will check for codes again. and post any new information.
