general problems of the 2023 Toyota Tundra - part 1

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 dealer service center where it is currently located. When I dropped it off the service rep said he hasn't seen anything like this. Prior to this incident I had no issues with the truck and it was last serviced by the dealership on March 4, 2026.

The contact owns a 2023 Toyota Tundra. The contact received notifications of NHTSA campaign numbers: 25v322000 (exterior lighting) and 25v767000 (engine and engine cooling); however, the parts to do the recall repairs were not yet available. The contact stated that the check engine warning light was illuminated. The 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 failure and informed the contact that a loaner vehicle would be provided if the engine failed. The failure mileage was approximately 26,700.

Toyota has not provided solutions to two of three recalls. This has been nearly a year and no solution.

Recall number 25v-767 engine may stall during driving. I was told by my local tempe Toyota dealership that my engine was going to be replaced and they would contact me when my line number came up. Now I learned that Toyota can't keep up with the demand so they are going to scan vehicles to see if there is any damage. My vehicle only has 20,000 miles on it so how can a scan determine that the engine will not fail at 60k. That's like telling someone that needs a heart transplant that there heart is beating good today so they don't get the transplant. Do people need to die to make Toyota liable. Toyota knew these vehicles were bad but they were allowed to continue to sell them year after year. It is a fact the #1 main bearing is defective. I don't feel comfortable putting my family in a vehicle that can seize up while going at a high speed. Nhtsa it is your job to hold vehicle manufacturers to a high safety standard.

The recall was issued may 2025 and still has no remedy, bulletins state anticipated remedy in 4th quarter of 2025, we are in middle of 2026, over a year since the recall was issued another recall issued November 2025 with no remedy yet.

I own a 2023 Toyota Tundra that is part of the major engine recall due to machining debris in the 3. 4l v6 engine. A few days prior to the failure, I called the dealership to raise concerns that the acceleration was starting to not act right. Despite this, while driving at 70 mph on the highway yesterday (may 22, 2026), the engine suddenly failed and died without any prior warning, it is my belief that this is due to the open recall. This created a very dangerous situation as I was traveling at highway speed and could have been rear-ended or lost control of the vehicle. The truck had to be towed to the dealership. The truck now has 33,000 miles. I purchased it used for $49,000 with only 11,000 miles. This is the same known defect Toyota has issued a recall for, yet my engine still failed catastrophically. I am extremely concerned that this failure has caused additional damage to the transmission, drivetrain, or other components. I have completely lost confidence in the safety and reliability of this vehicle. Even after the planned engine replacement, I do not feel safe driving it due to the risk of future failure and the known history of this defect. I am requesting that Toyota provide a full buyback or replacement because this sudden engine failure at highway speeds poses a serious safety risk. Toyota has been notified, but I want this incident officially documented with NHTSA due to the widespread nature of these engine failures in 2022-2023 Tundras.

While driving the vehicle on a public roadway at approximately 70mph, the vehicle suffered a sudden and catastrophic powertrain failure without timely warning. The check engine light illuminated, the physical engine oil pressure gauge dropped to absolute zero, and the dashboard immediately flashed a critical "hybrid system malfunction" warning. > this mechanical and electrical failure triggered an instantaneous, total loss of motor power while traveling live lane with traffic behind me. The vehicle immediately stalled and became a completely inoperable, unresponsive rolling hazard. The vehicle failed to restart and left me stranded on a narrow shoulder which was very hazardous as traffic coming at high speeds could have easily rear ended me. The vehicle required a flatbed tow to an authorized Toyota dealership, and after submitting a case with corporate hoping for a trade assist(as my wife no longer feels safe in this chassis), I have been told it will take up to 45 days to process this request. I made a significant investment in this vehicle in January of 2023 and have since methodically kept up with maintenance, with hopes this vehicle would last me 10+ years. I find it highly inexcusable for Toyota to not consider speedily helping a loyal customer in this situation and making it right in a timely manner. I am now being offered a vehicle the same as mine of the current year and with me having to put over 22k in equity to close the gap. I should not be left on the hook for something that put my safety at risk and now has left me without the ability to travel as my family has lost their main method of transportation. Manufacturing defects should not come at the customers expense.

The contact owns a 2023 Toyota Tundra. The contact stated that while accelerating from a stop the vehicle stalled. There was low voltage message displayed. The contact stated that there was metal inside the oil filter. The vehicle was restarted and driven to the residence. The vehicle was taken to the local dealer but was not diagnosed or repaired. The dealer informed the contact that the part to do the recall repair under NHTSA campaign number: 25v767000 (engine and engine cooling) were not yet available. The manufacturer was not contacted. The failure mileage was approximately 14,500.

The 2023 Toyota Tundra hybrid’s powertrain design may be insufficient to maintain basic safety maneuvers (specifically "limp mode" or emergency clearing) during an engine failure while operating under high-load conditions in mountainous terrain. This creates a life-threatening hazard for the occupants and other motorists. ?statement of fact: as an owner of a 2023 Toyota Tundra hybrid, I primarily utilize this vehicle to tow a 9,000 lbs travel trailer through the high-altitude, steep-grade regions of utah. These routes frequently consist of narrow, two-lane mountain passes with no shoulders and steep drop-offs. ? ?failure under stress: engineering logic suggests that engine stress is highest during heavy towing on steep grades. If a primary engine failure occurs in these conditions, the hybrid system’s battery and electric motor capacity are, in my experience, inadequate to move a combined gross combined vehicle weight (gcvw) of approximately 15,000+ lbs to a safe location. ?while the hybrid system may allow a light, unladen vehicle to limp to a shoulder under "ideal conditions," it lacks the torque and sustained power to move a heavy trailer on a grade once the internal combustion engine is compromised. ?in the event of a failure, the vehicle would likely become "dead in the water" in the middle of a live, narrow lane on a blind mountain curve. Without the ability to reach a turnout or even a marginal shoulder due to the weight of the load, the vehicle becomes a stationary target for other high-speed mountain traffic, posing a severe risk of rear-end collisions and multi-car accidents. ? I am requesting that the NHTSA investigate the performance of the Tundra hybrid’s "fail-safe" modes specifically under maximum towing capacity on grades.

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 since the initial incident, but the vehicle has documented evidence of multiple stall events and remains a safety concern. The vehicle is available for inspection upon request. Due to the sudden loss of power at highway speed and the inability to safely control or accelerate the vehicle, this issue poses a serious risk to the driver and others on the road.

Over the past several months my truck 2023 Toyota Tundra has randomly died, completely shut off and sputtered to a stop. After these instances occurred the vehicle has had trouble to re-start. As a result I took my truck into the local dealership in topeka KS, lewis Toyota, which did not complete any of the recall work, they said that the inicident could not be duplicated. For follow up, I took my vehicle to crown Toyota where its currently receiving body repair from an unrelated traffic accident. I have given the service manager ryan wingert the total background of what has happened verbally several times, outlining the vehicle randomly just shutting down and not being able to re-start until several minutes has past and computer reset occurs. I feel that the vehicle is un safe to drive and Toyota is not honoring any proactive follow up with my claim, stating that the dealerships have not been trained on the procedures to perform the work or the repair and pointing toward Toyota corporate offices for a fix. I'm exaughsted from the endless loop and I want to ensure I receive a safe and reliable vehicle back from Toyota. To date, the dealership has had my truck in there possession over two months with no resolution. The type of customer service and lack of follow up on critical safety items I feel puts our roadways at further risk of continual accidents due to Toyotas lack of engagement and follow up. I take full advantage of the freedoms we enjoy every day, being a service disabled air force veteran of over 20 years of service, I take great pride in the active checks and balances holding us all accountable. I appreciate your efforts and follow up regarding my claim. Dont hesitate to email me or follow up by phone. [xxx] - [xxx], thank you!

My 2023 Toyota Tundra hybrid's engine has expired and been confirmed by Toyota dealership and Toyota corporate. They are rebuilding the motor, which is outside of warranty but my specific truck is not on the recall list, therefor I will not get a new motor, but a rebuilt motor. I was put at risk of complete engine failure, leaving me stranded on the side of the road. The vehicle was towed to reliable Toyota dealership in springfield, mo who confirmed that I would need a new motor. They opened a case with Toyota corporate, which agreed to a rebuild motor, but not a new motor, as this model is not under the recall. There were zero warning lamps, messages, or other symptoms before the complete failure.

After coming to a complete stop to make a turn, throttle became unresponsive and then engaged. No warning lamps or noises.

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.

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 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.

Component/system failure: the failure involves the engine cooling system, specifically the radiator, fan shroud, and oil cooling lines. The oil cooling lines are improperly routed or positioned, causing them to press against the plastic fan shroud. Over time, this pressure deforms the shroud inward, leading it to rub against the aluminum radiator and create pinhole leaks. The damaged components are available for inspection upon request. Safety risk: this defect poses a serious safety risk due to sudden coolant loss and potential engine overheating. This can result in loss of power, engine failure, and unexpected breakdowns in traffic, increasing the risk of accidents, especially at highway speeds. Reproduction/confirmation: this issue has been widely reported among 2023 Toyota Tundra owners and confirmed through visual inspection by owners and independent mechanics. The consistent nature of the failure indicates a design defect rather than isolated incidents. Inspection history: the vehicle has been inspected, and deformation of the fan shroud along with visible contact and wear on the radiator confirms the issue. Dealerships have acknowledged the condition but refused warranty repairs. Toyota has not issued a technical service bulletin (TSB). Warning signs/symptoms: there are typically no warning lights or messages prior to failure. In some cases, coolant loss or overheating occurs only after radiator damage has already developed. Additional statement: this is a widespread defect caused by improper routing or clearance of oil cooling lines. Despite numerous similar reports, Toyota has not issued a TSB or recall and has denied warranty coverage, leaving owners responsible for repairs related to an apparent design flaw.

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.

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.

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.

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.

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.

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.

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

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.

On 1/13/2026 I took the car to Toyota dealership in riverside California to fix 25tb14 safety recall. On 6/3/2026, they did not fix it and I took my car back and stored it because it's not safe to drive.

I get random lags in thorttle engagement when starting from complete or rolling stops. When this happens, it behaves like there is a delay between the throttle input and the engine resoponse. Push the throttle to go, and no go, and after a delay of usually part of a second, then it jerks and goes. Most times there is no problem and the throttle responds correctly, but this issue occurs randomly almost every time I drive.

Throttle lagging issues and delayed acceleration.

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.

See attached document for complaint.
