2025 Toyota Tundra

I own a 2025 Toyota Tundra 1794 with the 3.4L twin-turbo engine. The engine failed at approximately 53,000 miles while I was driving on the freeway in Houston, Texas. I was traveling at highway speed when the engine suddenly lost power and the truck became unsafe to continue driving. I had to pull over to the shoulder of the freeway with traffic moving at high speed. My [XXX] daughter was in the vehicle with me at the time. The sudden loss of engine power at highway speed created a serious safety hazard because it left the vehicle disabled in active freeway traffic. The vehicle had been properly maintained with regular oil changes and normal driving conditions. After the failure the truck had to be towed to the Toyota dealership, which I had to pay for out of pocket. The dealership performed an engine teardown that took about one week. They informed me that the engine block and most internal components that come into contact with oil will need to be replaced. The dealership told me the failure is not currently related to the existing Toyota Tundra engine recall. The truck is currently at the dealership and they estimate approximately 30 days to complete the repair. The dealer also informed me they have multiple Toyota Tundra trucks waiting for engine repairs and that no truck loaner vehicles were available. My understanding is that a Toyota case number has been opened for this failure and that the diagnostic details are recorded in that report. I am concerned that sudden engine failures at highway speed represent a serious safety risk INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is a known issue on previous year vehicles. Gas pedal response is delayed excessively causing scenarios where one could become injured if attempting to pull out from a full stop or rolling stop expecting the vehicle to move and it doesn’t. Reference Toyota TSB-0111-22 for vehicle hesitation while accelerating. Brought my vehicle into a Toyota dealer in Scranton PA on 12/16/2025 with this info and they were unable to duplicate the issue along with stating that TSB does not apply to this year vehicle. Look online there are tons of forums stating this issue is still present in the newer year models like mine which is a 2025. This is a serious problem as it’s happened at random with no clear reasoning other than potential programming issue between the transmission and gas pedal coding.

When accelerating from a standstill, the car hesitates for 1 to 2 seconds after I press the accelerator pedal. This is a safety concern, especially when merging onto the highway (we have stoplight-controlled merge lanes where I live), where accelerating the vehicle is essential to a safe merge into traffic going 65+ mph. There have been no warning lamps.

Throttle lag When I accelerate from a stop, such as at a red light or stop sign, after I gently press down on the gas pedal, there is consistently a 1-2 second delay before the truck accelerates. This can cause potential delays in getting through an intersection, in turning in front of oncoming traffic, and getting going in traffic. This happens consistently since I’ve owned the vehicle since the summer of 2025.

Unintended acceleration. When you stop the truck, and have the brake on, the rpms go down to idle ~650. As soon as you lift the brake, without touching the accelerator, the vehicle starts ramping up the rpms and moving. On level ground it will go to 1000 easily before you have to stop it. It will pull up a grade even while towing my boat. If you're in a line a traffic, say at a traffic light, and the light changes, traffic moves and the car ahead takes off their brakes, and you do same, the truck starts moving faster than the vehicle ahead without touching anything. It's idling too fast without the brake and doesn't stay at idle once the brake is off before you push the accelerator. First the dealer told me everything was "Normal" - it's supposed to do that. I've been driving vehicles since 1962, so I think I know what I'm talking about. They told me to call Toyota. Toyota started a case. They took it in for an factory inspection because I think this might be related to a non highway collision with a bldg, I had shortly after I got it, I'm not sure. I put into park in a parking space but apparently it didn't engage, only into reverse. I was looking for something and the truck started backing up and hit the gas station bldg close behind. The anti-collision was off, because you have to turn it off to tow. And I hadn't turned it back on yet. This truck has way too many audible alarms and very annoying, especially when backing or exit the vehicle. I don't need to know that I'm out of the vehicle.

The vehicle has a recurring safety-related defect where there is a long, unpredictable pause (1–3 seconds) between pressing the accelerator from a stop and the truck actually accelerating. This hesitation occurs when pulling away from a stop sign, traffic light, or after braking to a stop in traffic, and is not normal throttle response or turbo lag. During this delay, the engine revs slightly but the truck does not move, creating a dangerous situation where the vehicle fails to respond when expected, especially in intersections or when merging. After the pause, the truck often surges forward abruptly, which can cause jerking and loss of control.
