    I had the firmware update on the brakes done on Oct 27. I needed to do a few things on the trailer before doing the drive test. The electric brakes now work when I press hard on the brake pedal (they always worked when I moved the lever). But, they do nothing in light to medium braking, and only have an effect on heavy braking when I set them over 8.5. If I had to pay for the firmware update I wouldn't bother doing it. It would be better just to use the money to add an aftermarket electronic brake control controller - Especially if driving through the mountains, etc. One bright spot is if I need to brake hard I will have brakes. Not even close to as good as my Tekonsha controller, though. I have my 18 month checkup next week so I am going to ask Toyota to confirm they actually did the update and explain my lackluster results. Nothing will come of it, but at least they will now about it.

    Ok, this is a weird one. Noticed the brakes seem about the same with the camper, maybe a bit better. However, now the truck brakes seem really "grabby" below on anything beyond light braking. Is this the case....or should I see a doctor about a possible brain tumor?

    I have a 2017 TRD Pro. I took it in to Toyota with the printed copy of the TSB and asked them to do the flash update. After keeping it for an hour they came back out and told me the TSB didn’t apply to my vehicle so they did nothing. My controller will operate two ways. 1.manually and 2. If I use hydraulic over electric setting. The trailer brakes are extremely grabby at low speeds and don’t seem to work at all at high speeds. It seems like my prodigy had some kind of progressive braking feature that prevented this. The built in controller is very convienent but I sure do miss my Prodigy. I only have a 3000# trailer so I’m not too concerned but curious if anyone uses a separate controller and is there a harness to plug into. My Tacoma had one but it was a pita to find.

    I went back to my Prodigy and an very happy. etrailer.com has a kit to plug and play into the tundra and ESPtruck.com has a great kit to mount it in place of your factory unit.

    They said they fixed it and the paperwork says they fixed it...but my trailer, apparently, can't read so it behaves the same to me.:frusty:

    Same here. The paperwork says they did the TSB update, but it made no difference. I wish I knew how to check if they actually did the update. Should find something out when I bring it in next Wednesday. Otherwise I am removing the Toyota controller that I paid for and junking it, then installing one that actually works. Also, complaining to Toyota for reimbursement. My last test drive with my trailer the truck brakes smoked a little and the trailer brakes were barely warm. I only felt brakes over 8.5 and then only when hitting them hard. The trailer brakes work fine with another truck.

    Has anyone noticed trailer brakes being "grabby" when not in tow/haul mode. When I shut off my truck at the campground office, tow/haul turned off. I did not realize this when I started the truck and drove on to my spot. Every time I tapped the brakes, the camper tires would lock up. I turned tow/haul back on and it stopped.
