Knowing when Toyota makes part changes?

Does anyone know how to find out when Toyota makes part changes to their vehicles? How can we find out if/when they are notified of an issue does it finally make it to the new trucks being produced?

Examples:

• When did they find out about wastegates and when did they update the parts?
• When did they find out about trans ticking noise and when (if) will they update/recall?
• When did they realize all the window rattling and rubber gasket issues and have they fixed it?

You guys get the point. Hoping we can see when these types of things are implemented so those buying a new truck for 60k can have more confidence they wont be ending up in the dealer with issues that already should have been addressed.

 

Good questions...

Also -

1. When did Toyota release new programming for the dead throttle pedal and delayed acceleration issue?

2. Starting which build date of trucks did Toyota resolved issue with engine bearings failing?

3. Were window seals design and manufacturing improved vs the original 2022 model even thought they still have same part number.

 

If only there was a thread that compiled all of Toyota's acknowledged issues and its solutions to those issues..
