2023 Toyota Tundra POWER TRAIN,ENGINE

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.

Engine started knocking, complete loss of power and had to pull over immediately to avoid any further issues such as an accident

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.

This has happened to me at least 6-7 times since owning as Jan 2024. Occasionally when stopped at stopped sign or red light, upon releasing brake and pressing gas pedal the engine will stall or stutter causing the vehicle to either hesitate to go and then launch or hesitate and not do anything. This is an issue as it has happened to me when trying to cross a divided highway and it stalling as I'm partially out in the middle of the road.

The contact owns a 2023 Toyota Tundra. The contact stated that upon depressing the accelerator pedal while at complete stop at a red traffic light or while driving at various speeds, the vehicle hesitated to accelerate as intended. No warning light was illuminated. The vehicle was taken to a local dealer, where the transmission software was reset; however, the failure reoccurred. The vehicle was not repaired. The contact stated that the vehicle was previously taken to another local dealer, where an unknown engine recall was performed. The manufacturer was made aware of the failure. The failure mileage was approximately 40,000.

Hesitation from vehicle when pressing gas coming from a rolling stop. Late response from vehicle which may increase risk of crash or injury when vehicle does not move.

Vehicle hesitates when accelerating from a stop. Feels like the engine may stall and the vehicle will not respond to throttle inputs. Very unsafe as I may not be able to accelerate to avoid an accident.

Excessive hesitation in acceleration from stop or slow start. No warnings displayed car has less than 18000 miles. The excessive hesitation poses a real danger when pulling into traffic or trying to avoid an accident. The truck can randomly take several seconds to respond to accelerator input. This issue halls been reported my many 2022 and later Tundra owner.

On several occasions I have a dead pedal situation on acceleration from a brief stop. When you press the accelerator, the truck does not accelerate immediately. Instead there is a second or two pause before truck responds to accelerator input. When crossing traffic, this hesitation has caused several situations in which i have almost been t-boned.

Throttle Lag/Hesitation when starting from a standstill. Same also occurs when slowly going up a hill, letting off throttle and then back on throttle - engine no response and causes vehicle to roll backwards before engine/transmission catch on again. No service center has looked at this issue yet.

I PURSHASED MY VEHICLE 4/13/24 AND ON 4/30/24 (IMPORTANT SEFETY RECALL APPEAR) I DO NOT FEEL SAFE IN THE IN MY CAR, BECAUSE OF SET RECALL ' ENGINE TO STOP WHILE DRIVING ' MY CAR IS NOT DRIVING SMOOTHLY LIKE IT SHOULD DRIVE A ''NEW CAR'' WHEN I START DRIVING THE CAR IT START TO SHAKING AND THROTTLE LAG 'LIKE THE CAR DO NOT WANT TO DRIVE' WHEN I CONTACT THE DEALER, THEY SAID " WE CALL WHEN THE REMEDY IS AVAILABLE'' MY CAR IS NOT SAFE TO DRIVE, I AM AFRAID TO DRIVE MY CAR CAUSE IT RECALL THAT IT HAS, I HAVE NOT BEEN ABLE TO ENJOY MY CAR LIKE IT SHOULD, CUASE IM AFRAID THAT I WILL GET ON AN ACCIDENT. PLEASE I NEED SOMEONE TO HELP ME, NO ONE IS DOING NOTHING IT BEEN A YEAR AND MY CAR IS GETTING WORST, AND I STILL MAKING PAYING ON THE CAR THAT I CAN NOT ENJOY. I NEED MY CAR FIX ASAP.

When in start and stop traffic when the vehicle is at low speeds below 5 mile an hour. The transmission does not properly downshift. This causes a severe lag in acceleration when needed in traffic or in Intersections. This delay is a safety issue due to causing a lack of vehicle movement when needed. The vehicle will basically not accelerate for a couple seconds until it decides to downshift. This happens continuously at speeds below 5 mile an hour. If you don’t stop completely and pause for a second or two, the transmission will not downshift properly. In traffic, you cannot do this.

When accelerating from a low speed (under 15mpg) there is significant throttle lag causing risk of accident

There is a lag in the accelerator. It happens 10 to 20% of the time. It is a one or two second lag on the gas pedal. Pretty critical when turning out into traffic. I have al most been hit twice due to car not accelerating properly. I have taken to the dealer twice. They have told me they could not recreate when driving

The engine has rough idle, the dealership says they see a misfire and they say is normal for the vehicle to do this, is a brand new vehicle I bought with 9 miles im at 14 thousands now, and the truck has died using the 4wd and completely turned off, i took it to the dealership and they said the same like the engine, they cleared codes and thats all, i dont trust this vehicle i left it stranded on the sand once and the recalls they dont have solutions for any of them, toyota is neglecting customers now.
