This Problem Across All Years
On June 20, 2025, my 2023 Toyota Tacoma (VIN [XXX] ed a sudden loss of effective braking during normal driving conditions (dry roadway, clear weather). The vehicle was being driven by my adult son. While slowing for a turn, the instrument cluster displayed a Pre-Collision System (PCS) malfunction warning and a Vehicle Stability Control (VSC) warning. The Driver applied the brake pedal continuously, but the vehicle did no decelerate as expected. ABS did not activate, and braking effectiveness was insufficient. During braking, the driver experienced reduced steering responsiveness. In order to avoid entering a busy roadway without adequate braking capability, the driver applied maximum steering input, fully loading the left side of the steering wheel with as much force as possible in an attempt to redirect the vehicle. Any reduction in speed occurred primarily due to the change in direction and tire to road friction, not effective braking. The vehicle was towed to a Toyota dealership. Dealer intake records document a PCS warning and no brakes upon arrival. Event Data Recorder (EDR/CDR) data shows continuous brake pedal application for approximately 5 seconds prior to the event, accelerator at 0%, and brake system hydraulic pressure reaching approximately 12.14 MPa (maximum recorded). Despite this, the vehicle did not stop as expected. No frontal crash pulse recorded. Toyota Motor North America later denied responsibility, asserting incorrect vehicle speed and stating that a CARFAX report indicated prior front-end damage. The CARFAX vehicle history report, dealer purchase disclosures, and service records show no reported accidents or damage. Toyota declined to provide brake system ECU logs (ABS/VSC/brake control modules). This incident raises concerns regarding a potential safety defect involving electronically controlled braking and its interaction with PCS stability control systems. Supporting documentation available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

Brake booster failure. When pressing and holding onto brake, it makes a buzzing/clicking noise. Just like the toyota prius brake booster recall/failure. Toyota claimed to be normal.

This vehicle has had judder issues since new when braking. It has been in the shop over 10 times for this issue with the last being this week. I conducted an internet search and see other new owners complaining about the same issue with no resolve. I was told I would be getting new rotors and when I picked my vehicle up from Toyota of Las Vegas on 10/24/24, however, they are only resurfaced, not new. They have been resurfaced 3 times, with the first being performed around 500 miles. With other owners having the same issue when the vehicle is still new, it has to be a defect in the original part. Even though my vehicle is under warranty, Toyota has yet to change this part out. It is a safey issue because it causes judder, sometimes severe while braking. Lastly, my vehicle was one of the first to have the welding debris recall issue. My issue started long before that recall. As you can see, my vehicle has lived in Toyota service centers since purchase and it's getting old. I hope you all can please help. Thank you.

Twice, while backing out of my driveway, the brakes have locked up. The brakes stay locked until you tap them repetitively for a few minutes. Then the brakes will slowly release while going forward, but only lock up again when put in reverse. The vehicle cannot be driven until the next day, then it performs normally. luckily this happened in my driveway before I got on to the street. When the brakes lock, it is violent, throwing me against the seat back. The vehicle has been to two different dealers, but they could not duplicate the issue. When this happens multiple brake warning messages pop up on the dash. The manufacture has not inspected the vehicle. In fact, when I reported it to them, and sent pictures of the warning messages, they insinuated that the pictures were not from my vehicle. The manufacture stated that they do not consider this a safety issue. I do not feel safe driving this vehicle. If the brakes lock while out on the hi-way it could cause an accident.

My vehicle was T-boned while driving through an intersection. After being hit, my vehicle continued moving forward, but the brakes would not engage or work. I pressed them several times and as firmly as possible, but the vehicle would not stop or slow down. As I approached a nearby curb, I pulled the emergency brake, which slowed down my vehicle slightly before colliding head-on with a fire hydrant and utility pole. The impact completely totaled the vehicle, yet the airbags did not deploy. Bottom line, in period of a few seconds, the brakes completely failed and the airbags did not deploy. The end result could have been devastating, but fortunately was not. The vehicle is set to be released to the insurance representative soon, but no analysis has been completed. A police report was filed. The vehicle is brand new (less than 2 months old) and no indications of fault or malfunction occurred prior to the incident.
