    Haven't been to the dealer yet to get the recall done as I wasn't too worried about getting run over but, today I had one of the cable ends come off of the brake arm. I pulled in the garage and set the brake as I always do and thought the e-brake pedal felt a bit light and went almost to the floor. I immediately knew it had to be the recall issue so I crawled under the back of the car to confirm. I always thought that to get the cable to slip off the arm you'd have to let the brake pedal slam back up to the release position but obviously this isn't the case. Every time I've released it I always let the pedal slowly follow my foot all the way up. Anyway, it was surprisingly easy to hook the cable back over the bracket so I guess it's time to take it to the dealer for the recall.

    Thanks for the photos.

    When I read Toyota's description of the issue and FAQ on this, I came away thinking that it was not a big deal -- because the only time you had to worry about this was if you left the car while it was running and not put in park (something I could not see myself doing).

    What your pictures make abundantly clear is far more straight forward: The defect can make the Parking Brake useless. Period.

    Not sure why Toyota did simply say that.

    Again as in another recall thread.

    Actually the one side still worked and kept the car from rolling but the pedal had to go much farther to engage it. So, in order for a total failure of the e-break to occur both sides would have to unhook.

    Most parking brake cables have some sorta T bracket, to keep the tension balanced. So if one side is kaput, the T bracket needs to skew way off before the other side gets some tension, and it's not going to be anywhere near as effective.

    Third gen, for example:

    I had the park brake recall done awhile back. It's just a little clip that attached behind that brake cable (where the ball around part in OP's photo). Very simple and takes probably 0.5293 seconds to do. Yet I waited 3 hours for them to do it at the dealership. If I knew what it was then, I could I have just just grab a piece of wire and a pliers and twist the metal wire around that part to prevent it from coming off..That would have saved me 2 hrs 59 mins

    One wonders why it was built this way. You would think testing would have shown this as a possible failure

    Maybe the parking brake lever at the caliper is not always releasing properly, allowing the ball to come out?

    I was under the impression that the recall mod was at the other end on the foot pedal ?

    Is this defect just on the 2016 and not the 2017? (First time I have heard of it.)

    sounds right. there was a delay during '16 production to correct it, and '17's were probably fine.

    I believe some early 2017 were affected. I remember my local dealer with a 2017, I believe, that was waiting for recall parts to complete the sale and delivery.

    Still seems weird, that when the parking brake is released, the cable and ball is lengthening, but the lever arm is not snapping back. What is the patch, is the added clip right at the ball, to prevent it popping out.

    Here's our third gen, same setup:

    (Looking at drivers side, parking brake is applied.)
