2023 Toyota Tundra

Since Toyota has recalled these engines, they have failed to produce a solution. This engine was recalled due to a safety concern, but yet they have not replaced the engine, nor do they even have a timeline for when it might be replaced. We use our Tundra for long distance towing with a heavy trailer. This has created a situation that is very concerning and my wife and I no longer feel safe in a truck that an engine can just seize in seconds leaving us not only stranded, but potentially in the roadway. The engine just dies, there are no warnings. We have lost a substantial amount of money on this because now the value of our truck has declined, which is not the standard Toyota had promised. Toyota had told all of us that they fixed this problem back in Feb. 2023. My build was a June 2023 model. It should have been safe and been taken care of, but Toyota didn't fix the actual problem back then. Toyota has not stood behind the vehicle or helped out for financial losses.

On my 2023 Toyota Tundra TRD Pro Hybrid at 72,241 miles, the vehicle started making a knocking noise. Engine turned off and wont start at all. Had the truck hauled to toyota dealership for service. After them having it a week, they called to let me know that the engine is completely locked up. Metal Shavings in the oil and motor wont turn over at all, even with a rachet on the crank bolt. Luckily I bought a extended warranty when i purchased the truck used as toyota is claiming only the non hybrid engines are under the toyota recall for the engines. After reading and researching they have the same engine just one doesnt have the hybrid assist on it. Toyota told me that the extended warranty company was coming today to check it out and would let me know where to go from here. They said its a very very uncommon issue on the hybrids but after researching that, that was a lie.

I am submitting this complaint to report a serious vehicle safety incident involving a sudden and complete loss of power while driving at highway speed. Vehicle Information: Make: Toyota Model: Tundra Model Year: 2023 VIN: [XXX] Incident Description: While driving at highway speed, my vehicle experienced a sudden and complete loss of power. The vehicle immediately lost propulsion, creating a dangerous situation for myself and my family. This event occurred without warning and required immediate action to safely exit traffic. Following the incident, the vehicle was taken to an authorized Toyota service facility. After inspection, the vehicle required a full engine replacement. The repair was completed, and the vehicle was returned to me. However, despite the repair, the incident has caused a lasting loss of confidence in the vehicle’s safety for highway operation. My family and I now avoid highway driving due to fear that a similar loss-of-power event could recur. Important Clarifications: • No collision or personal injury occurred, but the situation posed a significant safety risk. • The loss of power occurred at highway speed, not during low-speed or idle conditions. • The vehicle required a complete engine replacement following the incident. • The repair itself does not address the safety concern related to sudden power loss at speed. Current Safety Concern: Although the vehicle is currently operable, I do not feel it is safe to use on highways due to the nature of the original failure. The sudden loss of propulsion at highway speed presents a serious safety risk to occupants and other road users. I am submitting this report so that NHTSA is aware of this incident and can evaluate whether similar incidents may be occurring with this vehicle or powertrain configuration. Thank you for your attention to this safety matter.

Toyota has recalled vehicles (24V-381) with the exact same motor that I have, but my truck has not been recalled simply because it is a hybrid. Their reasoning is that the hybrid motor will allow you to still move if the internal combustion engine does not work. Many hybrid owners have stated when their motor died they could not move. Toyota needs to include ALL the motors in this recall, including the hybrid engines. This is a safety issue that needs to be addressed.

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.

Since purchasing this truck in 2023, the engine or transmission has exhibited a severe throttle lag/hesitation when cold—a 2–4 second delay in acceleration from a stop after pressing the gas pedal, followed by a sudden lurch, which creates a safety hazard when merging into traffic. No warning lights, error messages, or other fault indicators appear. The dealer has been unable to reproduce the issue because the truck is warm by the time it's inspected, and no inspection has been performed outside the dealership.
