2012 Prius, $5,500 repair estimate, :( T-SB-0003-21

I have a 2012 Prius with 100K miles. It went into limp mode. I took it to a local independent shop that specializes in Japanese cars. They quoted me $5,500 to repair it.

I was hoping someone could help me understand if the estimate looks ok? It mentions SERVICE BULLITIN T-SB-0003-21 and I have read some places that could be covered under a recall? But the shop didn't mention that, so I was unclear if maybe Toyota would pay to fix it?

Should I take it to a dealer to look at?
thank you!

Thank you. I tried that site, but it kept hanging up on me. I went to toyota recall website and searched my VIN, but it said there were no safety recalls or service campaigns.

This shop charged me $180 to diagnose the car. They have a decent reputation in now, but I have never used them before.

Would it be worth while to bring to a dealer?

 

Good news, I think Toyota is going to cover it! So we took it to an independent mechanic that says they specialize in Toyota's and hybrids, they wanted $5500 to do the work, said it was not under recall. We towed it to a dealer. They say they will fix it on their dime.

Not sure why we got different answers.
