2018 Toyota Tundra brakes problems

Filed Oct 10, 2024 · Brakes, Electrical · FL

This case results from the malfunctioning trailer brake ECU on 2018-2019 Tundras. There is a Toyota service bulletin T-SB-0036-19, which specifies an updated controller to replace the defective model. Part # : Original 89547-0C020 Update/replacement 89547-0C060 Toyota will not replace this defective part outside of the original warranty period despite the issuance of an updated replacement part. The service bulletin wasn’t even issued until 4/19 possibly giving no recourse to owners whose warranty had tolled. The newer part number, suggests this was a dangerous defect that was upgraded. A review of this matter online details this problem has frequently occurred. The reason it’s not more commonly reported is that a minority of Tundra owners tow trailers, and even fewer tow with electric brakes. Regardless, this is a significant safety issue where the Tundra owners are forced pay about $1,100 to repair this defective part. This matter should be elevated to a recall since losing the functionality of one’s trailer brakes is a very dangerous situation.

I am having problems with the integrated brake controller constantly disconnecting when pulling any type of trailer. When ever I pull a trailer I never know when the controller will disconnect and I'll lose brakes on my trailer. This happens at any speed while towing. This seems to be a thing for 2018 tundras, as I've read about many other complants.

2018 tundra integrated brake controller intermittently disconnects truck from trailer when attempting to brake. Truck brakes stop are activated but trailer is disconnected. Tires begin to smoke and there is a burning smell from the tiresnot being able to slow or stop the trailer. We have taken 4 trips and it happens on all of them. Toyota dealership said they don't have a fix. Hundreds of the same complaint on the internet. This form only allows date entry for one incident. But the occurrence is every trip. In fact, we don't have brakes connection now and toyota dealership says they don't have a fix.

I was driving down the road and got into the left turn lane and when I applied the breaks the pedal seemed extremely lose and the truck was unable to stop. Luckily there was no traffic and I was able to go up and make the turn extremely slowly. When I got home I noticed that the truck was leaking break fluid.

1st off, I drive a 2018 tundra, my integrated trailer brake controller doesnt apply brakes on any trailer. It throws an error message and will not work on any trailer type settings. Had trailer checked and tested with other vehicles and trailer works fine. And of course the same exact issue is all over the internet since 2016 and up, with no fix or responibilites taken on toyotas part. Not habing trailer brakes is a very dangerous situation and believe that if I paid for the brake system I should have to buy an aftermarket one just to pull my trailers safely. 2nd issue is once again electrical, the radio shut on and off every 10 minutes or so...will not keep presets saved etc, told toyota and they tried to download and update and said the radio wouldn't except the download. Of course truck is out of the horrible offered 30k mile warranty....so I have a 2018 tundra 4x4 that has a broken radio and can't even pull a trailer.....hard to wanna make a payment for that kinda stuff.

When its moist out. The cruise will auto cancel itself and the pcs failure lights up on the dash. Happens semi often. Dealer states they can't fix it but to bring it in when it happens again. The truck brakes for ghosts as I drive down the highway. They can't fix this either.
