2023 Toyota Tundra vehicle speed control problems

“-Our Toyota Tundra Hybrid suffered total catastrophic engine failure due to metal shavings found throughout the engine and oil system. This is the same issue that prompted NHTSA ID Number: 25V767000 recall of Toyota's V35A engines. The tundra is available for inspection. -Statement regarding safety put at risk by my husband: I felt a vibration from the engine compartment (seeming to come from the front right side) and then I suddenly lost complete power. I was traveling in the number one lane (the fast lane). I immediately put my hazards on and had to navigate to the number two lane and then over to the narrow shoulder under no power whatsoever. I had to navigate around multiple semi-trucks. This was a very dangerous situation and I barely got it over to the shoulder. If my teenage daughters were driving this car they likely wouldn't have been able to safely navigate it across two lanes with no power in the setting of multiple semi-trucks on a two-lane divided highway. Again, a very dangerous situation. I shut down the engine and waited five minutes and restarted it. Shifting into gear the warning indicator said 'hybrid system disconnected'. -The total…”

“was waiting for the traffic light to turn green. Vehicle in drive with foot on brake. the traffic light turned green, I took my foot off the brakes and pushed on the accelerator. Nothin happened. I saw another vehicle approaching at a high rate of speed behind me so I continued to mash on the accelerator. right before being hit by the car behind me my vehicle lurched forward a few feet then stopped again. I looked at the dash display and saw a "Hybrid System Malfunction" warning. Because of the traffic situation/location it was not safe to just sit in the road so I continued to pump on the accelerator. each pumped moved the vehicle forward a couple of feet. I did not turn of the engine because I was unsure what would happen so I continued to do that for about a mile or so until I could get to a safe place to pull over. during this time, I almost got rear-ended and side-swiped several times. Once stopped I attempted to start the vehicle several times and got the "Hybrid System Malfunction" display and the vehicle would not start. I waited for about an hour with the vehicle off and restarted the engine. I stayed off the freeway and took backroads to the closest…”

“While driving on a two-lane highway at approximately 80–85 mph and attempting to pass another vehicle, the engine suddenly shut off without warning. The vehicle lost all propulsion, and steering assist was significantly reduced, creating a dangerous situation and nearly resulting in a head-on collision with oncoming traffic. Warning lights including check engine and low power steering illuminated immediately after the stall. The vehicle would not restart for several minutes and was temporarily disabled in the roadway. The vehicle was later inspected by a dealership, which confirmed through diagnostic data that multiple engine stall events occurred at highway speeds. The inspection also identified system-wide electrical voltage drops and multiple communication faults between control modules. The dealership attributed the issue to a loose battery terminal; however, the diagnostic report indicates prior voltage irregularities and multiple affected systems, suggesting a broader failure condition. This incident is consistent with an active safety recall affecting this vehicle, which states that the engine may stall during driving. The failure has not been reproduced…”

“Throttle response is unpredictable. From a stop sign, acceleration is difficult to predict. Sometimes a one second delay occures before acceleration power is effected. With the time delay the throttle has been pressed further than normal. In heavy traffic, a collision could be possible. The problem got worse after a firmware update, during a safety recall to replace rearview touch screen. Pedal Lag problem is noted on Toyota Tundra forum.”

“Unknown. Intermittently when merging into highway traffic from the onramp, the truck will stall and I will lose acceleration. There will be a loss in power and the truck speed will not change. instead it will just coast with no ability to change speed. I have owned the truck for 1 year and 3months. I advised the dealer and they can not duplicate the issue.”

“There have been multiple times, since owning the vehicle, when there is dangerous throttle lag. I step on the gas to turn and nothing happens for a few seconds. It can be pretty scary when there is a car coming and the truck just rolls for a few minutes before accelerating. It’s become a major safety concern for my family.”
