I feel your pain!
I do not have any confidence in this car. I have even less faith in my local dealer. Its been in their shop twice and had the first update done with questionable results.
I know there is a newer reprogram available but that would mean a trip to the dealer. Think I will just live with what I have and drive my Toyota more.
It has never been to the dealer for any issues. It will even merge with traffic and not get me run over.
