2024 TOYOTA TUNDRA — Problems, Recalls & Safety Data

I am an automotive engineer. I have been involved with vehicle development programs in the disabled vehicle conversion community for over two decades and have numerous patents in that space. I have been involved with vehicle testing and calibration as well. My vehicle demonstrates a SIGNIFICANT HESITATION when the accelerator is pressed that is not consistent. I live in a roundabout dense location where timing an entry into a roundabout is easy using a normal vehicle. The 1 to 2 second hesitation where there is throttle input and no action at all from the vehicle (engine does not rev, no motive power observed) is very dangerous. I took this up with Toyota and my vehicle was checked out and "learning transmission" memory was wiped clean with me being the only driver was the remedy. The issue got better for a short time but is back and this morning I pulled out thinking there was plenty of time in front of a bus a good distance away and the lack of motive power for a full second or two resulted in a near miss. This vehicle has about 20,000 miles and was purchased by me new. There are NO WARNING LAMPS, and no DTCs thrown when this happens. I have seen several videos where people cite the same experience and a website where there is a class action lawsuit in place regarding this issue. This is completely separate from the engine recall issue. I feel as though this issue is a significant safety risk.

My 2024 Toyota Tundra imax hybrid started off with a knocking sound. I took it into a certified Toyota dealership to have it inspected. I was then told that they had ordered a part it needed to fix the problem. After not hearing back and the knocking getting louder. I reached back out and took it back for further inspection. They then told me that it needed a system update. After running the update, a couple of times later after diving the Tundra, it had a power issue when pushing the gas to accelerate. I then reached out to Toyota once again and took it back to be serviced. They told me that they test drove my truck and had no issues with acceleration. So I went and picked it up. Just a couple days after receiving my truck back, I was at an intersection with the blinking turn signal and attempted to take off when the truck completely stalled out. I had two cars almost crash into me, but barely missed! I started the truck back and went directly home. I then told Toyota about the situation and they told me to bring it back in. It then stalled again when I was taking it to the dealership. Once I got it back to the dealership and told them what happened, they said they would look into it. After they had it the first few days I never heard anything back, so I called to see what was going on with my truck. They told me that they were waiting to hear back from corporate Toyota for further directions from TAS. My truck then sat there for a few weeks. I kept reaching out to see what was going on and all they kept telling me is that they were working on it, and that they test drove the truck, but couldn’t get it to stall. I had the Toyota app on my phone, showing the mileage, and the mileage had never moved. Letting me know that they hadn’t actually test drove it. So after all of this, they never did any work on my truck. I was now scared to drive it, and honestly didn’t want it back.
