My brand new 2012 CM Tundra TRD Off Road had the same issue.
I actually heard a loud whirling noise while driving the truck home from my brother in laws on Friday night, I pulled over and shut the truck off and I could hear what sounded like a fan slowing down and shutting off.
I then drove the truck on Saturday with no issues, and then went to start the truck Sunday morning, CEL on and truck in LIMP mode.
I called the dealer near by and took it down to them this morning, I explicitly stated I did not want them to just flash the ECU and I wanted the issue investigated.
They called me 6 hours later, tell me the truck is done and all they had to do was flash the ECU.
When I got down there I argued again that this is a major issue with these trucks and I didn't want them to just flash away the problem. I explained that next week is Christmas and I'm taking my family to the mountains for a ski trip, what happens if this issue occurs again when I'm 6 hours away from town. Their answer "Toyota Roadside assistance"
I took the truck and drove it around for about an hour, then shut the truck off, loud whirling noise again, started and shut the truck off multiple times and about 75% of the time the noise is there upon shut down of the truck.
I recorded the noise on my phone to show the dealership, then I called them back. The lady explained to me again that on 2012's they flash the ECU and it fixes the problem.
Next call will be to Toyota Canada first thing in the morning, I don't trust the truck now and I'm scared to take it anywhere, I know its going to fail again.
I never heard that whirling sound ever until Friday night and it failed 2 days later.
Code the ECU threw was P2445 AIP Valve Stuck
The worst part is that they are arguing with me at the dealership that this isn't an issue with 2012's and that Toyota fixed it, I will be pointing them to this site tomorrow.
