Warnings problems of the 2019 Toyota Tacoma

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!.

This describes false alarms by the vehicle electronics. About once every four to six months, the center display on the dash says, "brake," and a sonalert-type steady beep comes out of the dash. This happens with cruise control on. In two cases, there was no vehicle in front of me on the road. I could not see any source of radio signal or radar interference (emi) in the area or nearby. In one case, there were no vehicles nearby, no weather or other radars nearby, only a television translator station about two miles away. The brakes may have been applied in some cases but generally are not. Weather has been sunny and clear in every case when this occurs. So far as I can tell, these are random false alarms with no apparent emi cause. They seem to be getting less frequent. I get frequent and reproducible lane departure warnings with certain "fog line" configurations used in my state or with random tire skid marks.
