...tens of thousands...Darn right! There is a group of probably tens of thousands shuddering Camrys out there and it is real. I've read about everything Sump and other owners have posted and they have done major research. This is big!
According to my local dealer they haven't seen even a single Camry with failed TC yet. They are updating soft, but haven't filed a single warranty claim yet.
I know 7 people that own 2010-2014.5 Camry (+ 2 of mine cars) and none of them experienced shudder and at least 3 of them + me not even planning to update TC software.
Are we all just lucky?
