my '13 OB 3.6r was re-engaging poorly and just acting bad. i took it in on fri for a "relearn" patch since apparently the old "learn" patch wasn't doing so well. i drove it around the block aggresively (since it seemed the agrressive driving caused it to rear its ugly head) a bunch after, at the beginning of the drive, the behavior was as before. but then the actions became more subtle. now, the car barely does it but the behavior is still kind of there, but, now where near as bad.
