I think that many people are experiencing the same issues. I have had all the software upgrades and given plenty of time to "re-learn" driving patterns and this morning the car lunged violently as I was pulling out of my driveway in front of my neighbor in his Lexus LS. The other things you will likely notice is high reving and late shifts on any steady incline if you have the same issue. I have said before I also think this is having an impact on gas mileage. My current problem is that I cannot get my service guy at Tom Williams BMW to call me back.
