Yeah, when I drove my car home from the dealer the shuddering was really bad. If I drive to the store or someplace close to me it isn't as bad. But after about 15 minutes (or on my commute to work) it just get's ridiculous.This doesn't make me feel better. The shuddering was worse than usual on my drive home from getting the update. I assumed it needed to learn again. I noticed that while shuddering (this only happens in 6th gear) the RPMs will flair about 250. I was barely going up a grade at 55 MPH. I normally drive on that road at that speed and don't have any issues.
I also have been keeping tabs on the weather conditions, nothing really seems to change - cool mornings or super hot in the afternoon - same shuddering.
