The Aqua is the JDM version of the Prius c. Maybe you would get some good help by making a post in one of the Prius c forums.

I did receive the letter. You should call Toyota Care at 800-331-4331. Ensure you are associated with the VIN of the vehicle.

Details of the repair experience (and other details)
* Over the weekend of 11/12 and 11/13, my car was making very loud sounds. Not just the normal sounds after you turn off the car. Much louder and longer. It sounded like air was being released from a balloon when you pull the opening so it makes a sound.
* On Monday, 11/14 I was driving to work on cruise control doing 70mph. The car dang and the Brake light, ((!)), ABS and VCS lights turned on. I turned around and went to my local repair shop. The lights turned off in 10 minutes and never came back on. I heard the same noises as above and they stopped in a few minutes.
* The repair shop diagnosed the problem as C1391, they wrote on the receipt:
"Trace to internal leakage of brake actuaror assembly. Toyota needs to replace & reprogram."
* I called the Toyota Dealer I bought the car from. They did not mention the Warranty Enhancement Notification - ZG1
They said it would cost $2,600 ($1,700 part and 6 hours labor). I set up to bring in on Saturday 11/19.
* I checked out PriusChat and saw the postings about the mailing. I remembered Toyota sent me something and found it and thankfully it was for the brake actuator.
* I called Miller Toyota and mentioned the notification. I asked why they didn't tell me that there was one on the car (they can see it on the VIN). They said they would have told me IF it applied.
* When I dropped off the car on Saturday 11/19, I showed them the receipt from my local receipt shop with the C1391 code. My repair shop told me they DID NOT clear out the history frame.
* I was starting to be concerned that they would not find a current problem if the light was not on. I asked the service advisor if they would fix it under the warranty if the lights were not on. He kept talking around the answer. I asked to speak to the mechanic. I told him I might as well take the car home until the lights come on and stay on and hopefully it will occur again before December 2017.
* The mechanic came out. He said "How do you know it is the brake actuator." I told him it went to a place where the mechanics are certified in some way by Toyota and specifically Prius. I have seen the certificates on the wall for their mechanics. He said, "No one is certified outside a Toyota Dealer." I said the computer codes they pulled said C1391 and they wrote it on the receipt and said they kept it in the history frame. I reiterated that if the lights are not currently on, will you fix it under warranty. The service advisor was leaning towards saying no. The mechanic then sternly said to the service advisor, "We know this is a known issue. Let's just fix it so it is right." THANK GOODNESS. Someone that is reasonable.
* So they told me they would repair it under the warranty.
* I got to rent a 2016 Prius for 4 days which was great.
* Car was ready yesterday 11/23 and we picked it up and it was replaced.

Hope this helps someone.
