I believe my 535ix has it too. I very much wanted to believe it didn't being a July 27 build; but I felt it. Then my daughter drove it for the first time. She pulled out crossing traffic with what should have been plenty of space/time & we froze in oncoming traffic for a second. It was close; and luckily no accident. She said, "I pushed on the accelerator and it paused."
Can anyone say DEFINITIVELY the number of the software patch / update that fixes this problem? How could we not have the latest software being August builds??
