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

The other day I was slowing down on an off-ramp and all the sudden had no brakes, or at least no power brakes for maybe 30 feet and then all of the sudden power assist came back and slammed hard on the brakes. If there would have been a car at the stop sign I would have rear ended them. Pavement was dry, No ABS light, no codes, everything has been normal since then. I have noticed that the electronic brake booster on this truck "cycles" every few brake applications resulting in inconsistent braking power, which is especially noticeable at low speeds. I have been told this is normal for these trucks. Has not been inspected by anyone as I cannot replicate the issue.

I currently own a 2019 Tacoma with around 70,000 miles on it. I keep up with all the Toyota recommended maintenance services to make sure my vehicle is well taken care of. So, while driving the vehicle on the interstate it drastically slowed down on its own and I could not get the gas pedal to engage almost causing a rear end collision. This also happened on two other occasions at lower speeds. My display stated I was having issues with ABS, Collision, and that I was pressing the gas pedal and break at the same time. My vehicle has been at the dealership for 4 days now with no resolve or any answers to why the vehicle is slowing down on its own. I feel the vehicle is a health/safety issue and I will not drive it until the issue is resolved. The computer was also flashed by Toyota a year earlier as I was experiencing a lag in engine engagement and high rpm's when the vehicle shifted from first to second gear. Something the tech noted he experienced driving it. It's also an issue I've had since purchasing the vehicle. I had to bring the vehicle back a month later as it started doing the same thing but was told they could not find any issues. I have found many other forums and spoke with other Tacoma owners who have had similar issues. I feel Toyota is definitely aware of the issues but not addressing them! I hope to get some answers soon!

My car while driving every so often miles will have the abs light go on with the traction control light and the amb symbol going off. When plugged into device at auto zone code C1422 stating the master cylinder pressure sensor zero point high. I’ve tried replacing the break light switch which is a common repair for people with that problem I’ve checked all harness and wiring all is intact and undamaged/ no water damage. When I look up my vin number in kellybluebooks website a recall appears for a brake master cylinder recall for improper machining of the brake master master cylinder. Which will cause internal damage of one of the seals, affecting brake performance. It affected 44121 of vehicles of my year. But when looked up in this website and Toyota no recalls appear which is strange. The defect it has when the abs light and etc. lights go off is it will force the car to stop moving by locking the brake system and smoking out the calipers till brought to 0mph which is very dangerous when operating in the freeway as cars behind my aren’t expecting a sudden stop. The repair is to replace the whole master cylinder. Which Toyota would want me to pay but it should be a defect from a recall.

I was at a stop light and when the light turn green I started driving forward and the ABS/ Brake lights on instrument cluster came on with repeated blinking. I slowed off the gas to apply the brakes. Brake pedal went to the floor with no brakes or slowing down at all. Luckily no one was in front of me and I had to pull the emergency brake. It was the only brakes I had at all. Once vehicle was towed to the nearest Toyota Dealer I had them diagnose the problem. Right rear wheel had leaked out fluid due to the rear brake cylinder failing. Upon repair of all brake pads, rotors, brake shoes, brake drums, both rear brake cylinders the problem was still an issue. Costly amounts of money already being spent to find out another failure with the Brake Master Cylinder/ Module. That part alone is also very expensive. Research has shown that the 2018 and 2019 Toyota Tacoma’s did have history of faulty brakes in turn possibly causing an accident. For my case on the road I was lucky. I can’t understand a loyal customer of years with Toyota that the company refuses any sort of aid and assistance in the matter. Why did the recalls end? Especially if this affected not just the 2018 model but the 2019 model like my Tacoma as well. For such low miles and no abuse this vehicle has faced other failures not only with the brakes alone. Vehicle is still with the Dealer at this time. Requesting some assistance in the matter please. Thank you!

Vehicle is designed in such a way as to allow moisture accumulating in drivers side floor mat and carpeting to wick upward and be deposited on the primary vehicle wiring harness located in the drivers side kick panel. The moisture collected travels down into the backside of the various female connectors and corrodes the conductors and receptacles that result in short circuits between the various vehicle components including the ignition, engine shutoff, temperature sensors, Antilock Breaking, Blind Spot Monitoring, Fuel Gauge, Forward Vehicle Lighting (high and low beam), Security, Traction Control and other critical vehicle systems. On February 5th, 2023 I returned to my vehicle to find the security alarm sounding in the parking lot of a local business, both the keyless entry system and key-fob were unresponsive and would neither silence the alarm or unlock the vehicle. After manually unlocking the door handle the alarm ceased, the vehicle started as normal and then began indicating a failure of the BSM system, while underway the ABS indicated it had also failed and upon arrival at our destination the engine would not turn off even with the emergency shutdown routine prescribed for unintended acceleration cases. In addition, the high beams would be triggered by unrelated button operation occasionally fail to turn off, the fuel gauge, temperature readouts and climate control provided unintelligible values. The vehicle was returned to to dealership where it was determined that water from the floormats was able to contaminate and cause systemwide failure. The repair was to replace the entire wire harness which would not be covered by warranty. On 3/15/2023 I reached out to Toyota Headquarters' Customer Engagement team and was advised that Toyota was aware of the problem and had no interest or obligation in rectifying the situation, regardless of my concerns that this presented a clear safety hazard to both operators and the general public.
