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. …
My check engine light came on when I was traveling in Oregon. I didn't notice any major changes in my vehicle's performance. Drove it all the way back to Colorado without issues. It went off and came back on several times. I replaced the cabin air filter, engine air filter and put fuel injector cleaner in the vehicle. Finally I took it in to the Toyota dealership to get an oil change and then the check engine light came back on. I paid for them to do a diagnostic test and they stated they were almost certain it was the 2nd fuel injector running rich. Brought it back a week later for the repair. Fyi...I was still getting 20 mpg in fuel and I wasn't noticing anything major in performance. They replaced the fuel injector and then the check engine light came back on with a different code. They are now running "another" more expensive diagnostic test and I still don't have my truck. …

Water leaked through the third brake light assembly into the cab roof, soaking the ceiling, seats, and carpet. This caused extensive mold growth and electrical corrosion near the control modules. The affected systems include the third brake light seal, cab roof, interior materials, and ECM (documentation attached). The truck remains at the dealer and is available for inspection upon request. The entire interior is contaminated with mold, creating a serious health hazard, and the vehicle cannot be safely driven or occupied. The leak also damaged electrical components, posing a risk of malfunction or short-circuit while operating the vehicle, and it is currently undrivable due to this damage. The problem was confirmed by Toyota of Clermont, which inspected the truck, documented the damage, and provided a written estimate exceeding $8,000 for repairs (copy attached). …
Due to the fact that we never test drove the 2019 Toyota Tacoma that we were given to purchase, and my husband drove the vehicle home I did not have the chance to try the vehicle until we arrived home. The first time that I sat in the vehicle, I felt extreme discomfort and electric shocks from the vehicle, very similar to the electric shocks that I received from the 2017 Toyota prius. My husband thought that it was caused from my health condition from my car accident and he agreed that, since I did not feel any discomfort driving the sienna, he would be the only that would drive the Tacoma and that I would primarily drive the sienna. …

As the hu reboots, driver is unable to use rear-view camera and any other feature displayed in hu. Road attention is affected since driver is distracted by the screen going black and on again. Also if driver is in a call has to end call from the phone and call again using the phone. No message or error code was displayed on hu. Dealer asked to film the issue with the cellphone in order to service the hu.

Moreover, I found in forums and youtube people reporting this rebooting issue in entune hu since 2016. …
