2023 TOYOTA Tacoma

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.

On November 14, 2025, at approximately 0200 hours, in Fresno, California, I was driving southbound on Highway 99 at approximately 70 mph using cruise control. It was raining heavily at the time, and visibility was significantly reduced. I was traveling in the middle lane when I suddenly felt what I believed to be an impact on the driver side of my vehicle. Due to the weather conditions, I was unable to visually identify what struck the vehicle. Immediately prior to this event, I noticed faint headlights in lane 1 (fast lane), but I could not determine whether that vehicle made contact with mine. At the moment of the perceived impact, the side curtain airbags deployed unexpectedly. I initially thought the deployment was a collision with another vehicle because the force felt like a physical impact. Once the curtain airbags deployed, I immediately lost control of the vehicle. Steering became impossible, and the vehicle veered off the roadway, ultimately coming to a stop on an embankment adjacent to the highway. California Highway Patrol officers responded to the scene, took my statement, and inspected the vehicle. They reported no exterior body damage consistent with a collision. The following day, I visited the tow yard and conducted a daylight inspection of the vehicle, confirming that there was no visible impact damage on the body panels or exterior surfaces. After the on-scene investigation, the vehicle was towed, and the responding officer provided me with a courtesy ride. As a result of the incident, I sustained minor injuries, including whiplash, road rash on my left shoulder and upper forearm, and soreness in my neck. This event involved unexpected deployment of side curtain airbags without any confirmed collision, leading to loss of vehicle control, roadway departure, and driver injury. I am submitting this complaint for investigation into potential airbag or sensor malfunction.

Engine began making abnormal ticking noise, heard primarily on the passenger side of vehicle. Upon removal of valve cover for inspection, found that there are chunks of camshafts breaking off causing the noise. Appears to be a manufacturing defect. Local dealer said they have seen this issue before. This issue could result in catastrophic engine failure and/or loss of power and cause a crash. My truck has 70k miles on it, regularly maintained and operated.

This vehicle thermostat and sensor system are faulty! My sensor started lighting up within a year and half after purchasing. Engine was not overheating at first, they said it will eventually happen and it did; all dealers said to replace but I was out of 360000 miles due to commute to Seattle. This vehicle is less then 3 years old and should have this item listed specifically in power train warranty since connected to engine directly. If engine overheats it is no longer usable and truck is useless! Engine warranty if this is a know issue from Toyota dealerships. Contacted 3-4 dealerships in the state of WA and all had known of issue. One dealer stated anything from 2020 to current has had thermostat issues. This is serious concern knowing the engine can seize up! Their thermostat and sensor should not be a combined item in my opinion. Please advise and or confirm this is an issue that should be looked into. If the engine overheats then the vehicle could cause an accident! This is a huge safety risk that can be avoided! I work and make it from paycheck to paycheck this was very expensive to fix and had to paid out of pocket. Please help others be aware of situation!
