Automatic Emergency Braking problems of the 2019 Toyota Tacoma

Approximately 100 feet from the vehicle, I rear end of the car in front of me. When I hit the brake pedal it didn’t seem like it stopped the vehicle I ran into another car and totaled the Toyota Tacoma. Conditions for dry and cloudy and road construction nearby.

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!.

Coming back home at 15:00 on 12 /22/22 it was light snow day on two lane county road my wife was following back for are mother in laws , west snoqualmie valley road carnation washington , speed 30 miles per hours I was coming into a turn that cautions 35 miles or less and the. My dash comes up a yellow triangle with a exclamation and my brake pedal disappears out from under my feet and the brakes lock up and slide of the side of the road into the grass , put the truck into park then I try to put engage the brake pedal up towards me with my foot and the motor stalls /cuts out , I push the start button system comes back on and out into four wheel drive to get out of the grass/ cow field and the check engine stays yellow . I take it Toyota and they tell me everything is fine and it was just a traction issue with the program of the truck.

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.
