Engine And Engine Cooling Problems of Toyota Tundra - part 1

Vehicle is subject to two active safety recalls, both listed as “remedy not available. ” one recall involves a potential engine defect related to manufacturing debris, which may result in engine damage and sudden loss of motive power. Manufacturer recall documentation indicates this condition may increase the risk of a stall, particularly under sustained load such as towing or highway operation. A second recall involves reverse lamp failure, which reduces rear visibility and may increase the risk of a crash when backing. No failure event has occurred. However, both safety defects remain unresolved, and no repair or timeline for remedy has been provided. The vehicle is used for towing and hauling, which requires sustained engine load. Due to the risk of engine stall under load and the absence of manufacturer guidance regarding safe operation, use of the vehicle for towing and long-distance travel has been limited. These conditions have been confirmed through manufacturer recall notices. The vehicle has not been repaired because a remedy is not yet available. No warning lights or symptoms have been observed. The concern is based on the nature of the defects described in the recall and the lack of available repair or operational guidance.

My 2024 Toyota Tundra platinum (VIN [xxx] ) had multiple times where I had delayed throttle response which created close call of accident while turning. I researched my VIN and it is subject to safety recall 25ta14 for v35a engine stall due to manufacturing machining debris causing main bearing failure. Toyota has issued this recall but no repair remedy is currently available. The authorized dealer (ed martin Toyota, indianapolis, indiana) has confirmed they do not have authority to perform the repair and cannot provide a remedy timeline. I have surrendered the vehicle because I do not feel safe operating it. I am without transportation indefinitely. This vehicle has also been subject to four additional safety recalls: 26ta02, 25ta10, 25ta06, and 24ta02. I previously filed a formal buyback claim with Toyota motor north America (claim no. Xxx) in November 2024 which was denied. Toyota has since issued three additional recalls on this same vehicle. I am requesting federal intervention and investigation into Toyota’s failure to provide a timely remedy for this safety recall. ” information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Nhtsa 25v-767 indicates potential issue with manufacturing debris in the engine potentially resulting in engine failure. Recall status indicates "remedy not yet available". It has been over 4 months (11/6/25 to 3/19/26) since this safety recall was filed. This has been an unreasonably long time and Toyota should be compelled to initiate the remedy immediately and provide a detailed explanation as to why it is failing to meet its own code of conduct with respect to product safety and the law.

The engine lost complete power. This is a 2024 Toyota Tundra I=max force hybrid. The low oil pressure, hybrid malfunction, check engine lights all came on. I lost all power, steering, brakes, and had no hybrid assist. I was nearly hit from the back. I was able to get help from people to push it out the highway. There was no warning prior to this happening. I have read about all the engine problems from the 22 and 23 year models and recalls are out. There are no recalls for the hybrid 2024 engines, but this looks the same as what I am reading.

When at proceeding from a stop or a "rolling stop", the vehicle has delayed throttle response or lag. Causes big problem when trying to get into traffic. This has been ever since I have owned this vehicle.

The contact owns a 2023 Toyota Tundra. The contact received notification of NHTSA campaign number: 25v767000 (engine and engine cooling); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

I received recall (Nov 2025) for engine replacement due to safety failure of the engine and Toyota still does not have replacement. Also received recall for reverse lights that are still not avaialble (Feb 2025).

My Tundra truck is having throttle lag. I pull out into traffic and there is no power. I put the throttle all the way to the floor and still nothing. After 2 to 3 seconds the engine starts to slowly throttling up, but very slow and no turbo. This has happened at least 15 times now since I owed it in July of 2025. That scared me so bad I now have it at the dealer for diagnostics. They had better fix it, I almost got into a wreck.

The contact owns a 2024 Toyota Tundra. The contact received notifications of NHTSA campaign numbers: 25v322000 (exterior lighting) and 25v767000 (engine and engine cooling); however, the parts for the recall repairs were not yet available. The dealer was contacted, and the contact was informed that the parts were not yet available. The manufacturer was contacted, and the contact was informed that the parts were not available. In addition, the contact was informed that the parts could take eight months or more to become available. The contact stated that the vehicle was unsafe to drive. In addition, the contact stated that the vehicle was used to transport his wife and grandson to their destinations. The contact had not experienced a failure.

My vehicle is equipped with the same v35a-fts 3. 4l twin-turbo v6 engine and #1 main bearing assembly that is currently under federal recall for catastrophic engine failure (recalls 24v-381 and 25v-767). Despite the shared mechanical defect of machining debris and bearing tolerances, Toyota has excluded the I-force max hybrid models based on the assumption that the electric motor provides sufficient 'limp home' capability. I believe this is a critical safety oversight, as a sudden internal combustion engine seizure at highway speeds creates an unpredictable loss of motive power that a small hybrid battery cannot safely manage in high-speed traffic. I am filing this to urge the NHTSA to expand the recall scope to include hybrids, as the primary power source is fundamentally defective and prone to stalling without warning.

The vehicle while parked and not running on our driveway burst into flames and had large fire and explosions that burned the vehicle front half completely. The whole engine compartment burned and melted and destroyed the vehicle. No warning lights, no issues. Just burst into flames and destroyed the vehicle.

My Tundra has been having lagged throttle after takeoff for a few months now going into 2026. My truck is slightly over 50k miles and did well for the first 40k miles. Last week it went limp and gave a loss of power warning and check engine light came on. Then the very next day a parking brake assist warning came on. I brought it to the dealer and after 4 days they couldn't replicate the warning light but seen that the turbo had failure. They said they could not change the turbo since theres an active engine recall on my truck. My truck is sitting at the dealer with no committed date or fix for when my engine will be replaced. Not sure what to even do as im paying on a truck I cant even drive. Aside from this major issue ive had two window motors replaced and a non working hamstring leg rest motor. They instead offered to sell me a new 2026 which felt sleazy on their part. I will not be staying with my 2023 Tundra if and when I get it back knowing we only get a 1 year warranty and crate engines are already failing. Toyota is treating their faithful clients horribly on this issue they caused. Id go as far as saying this should be part of the lemon law act and more needs to be done.

This is an engine failure recall and after multiple conversations with my service advisor, I am being told that my "vehicle is not ready for the corrective action at this time". When I ask him what constitutes "being ready", he states that "the engine pretty must has to be dead". My reply, "in other words, I need to be stranded with an inoperable vehicle before Toyota is going to allow a claim submission?" his reply, "yep, that is pretty much it. " so, I am driving a car over mountain passes every weekend, late at night, just waiting for it to die for a known recall, and Toyota is not taking any action. This car only has 37,700 miles on it and it not what I expected out of purchasing a new Toyota.

While operating my 2023 Toyota Tundra trd pro under normal conditions, I started the vehicle and activated standard factory equipment including the seat heaters and window/mirror defrosters. Shortly thereafter, I noticed a slight acrid odor inside the vehicle, which quickly became more pronounced. I drove approximately 200 feet, and immediately returned to my driveway. Upon shutting the vehicle down, I observed smoke coming from the engine compartment. I opened the hood and confirmed smoke and signs of an electrical fire originating in the engine bay. I used a fire extinguisher to extinguish the fire and then disconnected the vehicle’s battery. No injuries occurred. The vehicle was not restarted and was subsequently towed to an authorized Toyota dealership for inspection. Visible damage is present in the engine compartment, including the main fuse/relay box and associated electrical components. The incident occurred without collision and during normal vehicle operation.

The contact owns a 2022 Toyota Tundra. The contact stated that while driving approximately 40 - 45 mph with the accelerator pedal depressed, the vehicle failed to respond as intended. The contact waited approximately one to two minutes, and then the vehicle operated as intended. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed, and the contact was informed that the vehicle was operating as intended. The vehicle was repaired as per the recall on the vehicle. The contact stated that the failure had occurred on several occasions. The manufacturer was notified of the failure and informed the contact about a possible buyback. The approximate failure mileage was 26,100.

1-2 second period of no throttle response from a rolling stop, then a sudden lurch of acceleration. This happens all the time with my family in the car and its really scary.

The engine repair was a short block only, even thoe the main bearings spun and sent debis threw the engine. #1 rod went as well. Apon recieving the truck back, with in 200 miles, I've had the same hesitation with the engines as I had just before the first engine failed. Took it by the dealer and no issues found. Oil preasure stays up and temp normal. I've had many issue with throtle lag sence day one. The milage has stayed in the low 11 gpm when before I would get on average 14 to 16. Dealer stated Toyota would make it right if the engine fails again. Very unhappy with Toyota as I feel they are just kicking the can down the road.

The engine in my 2026 Toyota Tundra has significant throttle delay/lag when its cold - even if I let it warm up - it still has significant delay in throttle response - the truck has poor light throttle response and then lurches (even with the most minute progressive throttle input). This almost caused an accident where I nearly got t-boned because the vehicle crept a bit and then suddenly lurched quickly. The vehicle was also hesitant to reach 60mph (even though it was warmed up) after about 10 minutes of driving the vehicle started operating normally. I have a concern for safety everytime I drive this vehicle.

Hesitation/lag acceleration and stop.

There is a lag when you accelerate. Many people notice a throttle lag and I’ve asked the dealer to fix it, but they said it is not a recall.

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

Driving down the highway at about 50 mph. Went to pass another vehicle and engine shut off. Thank goodness was able to pull to shoulder and get towed to dealer. Could have been a catastrophic situation.

Complete engine failure on 2025 Tundra. Left me stranded on the side of the highway.

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.

Were were driving, my 2021 Toyota Tundra, just stopped running. No check engine lights had come on until the engine stalled as we coasted to a stop on the side of the road. We had it towed to the central maine motor in waterville, maine 04901. Central maine motor -Toyota service just got my truck in to a service bay today 1/29/26 and in formed me the failure was due to the fuel pressure module and a fuel pump failure. Toyota has other years of vehicles that they have issues recalls for and my truck has the same fuel system and fuel pump as in those year vehicles, but no recalls for my truck, a 2021 Toyota Tundra built in sept/oct of 2020.

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 was stopped and went to pull out of the gas station. With my foot on the throttle I pull out. And it would not accelerate. I had to pump the gas pedal I almost got hit by oncoming traffic due to the lack of acceleration this has happened multiple times very dangerous.

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.

The gas pedal has no response when coming to a stop and pushing on the gas pedal. Multiple times I come to a stop, push the gas, no response, 1-3 seconds later; the vehicle jerks forward. On occasion it has nearly lead to an accident and I do not feel safe in my vehicle.

Throttle lag happens 2-3 time a day in many instances due to the delay almost causing accidents.

Have severe throttle lag and/or hesitation when giving gas from a stop. It causes a unsafe condition when you give it gas to go and it hesitates so bad I have almost gotten into accidents. This has been happening since new. Currently 30k miles on the truck.

While pulling out into traffic, my truck will suddenly hesitate. It also caused a vehicle to hit me as the truck pulled out into the lane, then suddenly completely lost power. Dealer was unable to replicate. Has happened to me several times when at a stop light. This is slightly safer as traffic behind me is stopped or slowed. It feels like a throttle issue as it completely looses power.

Continue getting a 1-2 second delay when accelerating from a dead stop after pushing on gas pedal with normal acceleration- not just an “lead foot” acceleration trying to quickly clear my intersection & merge into traffic. Happens when engine is at normal operating system or just pulling out of my neighborhood onto a 45mph road on a normal temp day.
