Owner reports
Selected complaints filed with NHTSA by 2018 Toyota Tacoma owners, lightly cleaned up (personal details are redacted by NHTSA).
Pulling vehicle into the garage on a cold morning (15 deg F). Hydraulic booster/brake master cylinder suddenly stopped providing boost pressure and brake pedal dropped to the floor. With no braking effort able to be applied the vehicle was driven into the house at slow speed. No hydraulic leaks are noted and pedal height and brake performance seems to have returned. There is fluid in the master cylinder reservoir and it doesn't appear to be contaminated. Braking capability returned after placing the vehicle in park and then reversing. Waiting for insurance follow up to select a collision repair shop and have the vehicle towed for repair. Dash cam video of the incident is available and clearly shows braking occurring and then the vehicle speeding up or failing to stop. Was unable to upload the video due to size. …

2018 Tacoma DC TRD Off Road, V6, hydraulic brake master cylinder, 49,000 miles: Brake fluid leaking into the cab of the vehicle beneath the brake pedal. Brake fluid is leaking from the rear of the master cylinder, running down the push rod and dripping off of the brake pedal bracket. Brake pedal resistance is slightly reduced. First noticed something dripping on my floor mat in April of 2023. I wasn't sure what it was. It never occurred to me that it could be brake fluid. There shouldn't be any vehicle fluids under the dash. There is the possibility of the system losing enough pressure that the brake system could fail entirely causing an accident and possible injury. (same symptoms as the recall for the vacuum boosted master cylinder-internal seal failure) This part should last at least half the life of the vehicle. 5 years and 49,000 miles is very premature for this part to fail. …

The Break booster has failed or started since the break fluid is leaking inside the cab. And other trucks from the same year as my truck did have a recall for the break master cylinder failing. My breaks could potentially go out fully and I wont be able to stop. My problem has been confirmed by my independent service center. And also there's alot of other people having the same issue online. Since the floor mats show oil stains just like how I found out I was having a issue.It hasn't been confirmed by the manufacturer but I will be taking it soon to be inspection but since a recurring issue with multiple trucks online. I wanted to report it here so the recall could be extended to other trucks from same recall year. I noticed i was having a problem when I had to press down the breaks really hard to come to a stop. Then thats when I stopped and saw the oil on the floor mats. …
