* 2024 Toyota Tundra Limited non hybrid TRD Off Road with 43k miles with catastrophic engine failure with no warning. Started as a very slight ticking sound while doing about 60 mph level to slightly downhill. * I could only hear it with very light throttle input (between 2 and 5%). Past 5% and at 0 pedal there was nothing. This went on for about 1 minute then it started to get significantly louder and more noticeable with throttle input and while starting to go uphill. * Shortly after it started catastrophically knocking with dash saying loss of power and oil pressure. * I get it stopped and it immediately shut down on its own. Due to very little warning I was forced to pull over on a right curve of a highway potentially putting my family and as well as passing traffic in danger. * Engine leaking oil. Couldn’t find anything obvious where the oil was coming from. After doing some research it seems like the front and main crank seals started leaking. More noticeable on the rear seal. This was a dangerous situation because oil was leaking on the hot exhaust and could have cased a fire on the side of a highway. * The Toyota dealer has possession of the vehicle for repairs. They have not stated if it is possible to be available for inspection. * The dealer has inspected the vehicle and is in the process of ordering a replacement engine.
NHTSA complaint #11763527 — an unverified report by a vehicle owner.
Engine stalls or hesitates when taking off from a stop. When taking off from a stop the Truck will hesitate after the accelerator is pushed and not move forward. This hesitation causes me to push the accelerator more trying to get the Truck to move. When the truck does move it then lunges forward I assume because I continue to push the accelerator more trying to get the Truck to move. The engine in this Truck is also being recalled in Non Hybrid Models because they are seizing up. This is the exact same engine in the Hybrid and should be under the same recall for the engine seize defect.
NHTSA complaint #11763533 — an unverified report by a vehicle owner.
I am writing to formally express my concern regarding my 2024 Toyota Tundra, VIN [XXX], and the engine recall involving certain 2024 Tundra vehicles. I am very concerned about the possibility of engine damage or failure related to machining debris and the potential for loss of power while driving. This is a major safety concern, especially considering the vehicle is relatively new. I would like Toyota to confirm whether my VIN is included in the recall and provide a clear explanation of the required repair or inspection process. If my truck is affected, I am requesting that the recall repair be completed as soon as possible at no cost to me. I would also like confirmation regarding whether Toyota will provide a loaner or rental vehicle if my truck must remain at the dealership for an extended period, particularly if an engine replacement is required. Please document this complaint and provide me with a written response explaining the next steps and expected resolution. Thank you, [XXX] Vehicle: 2024 Toyota Tundra VIN: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is a follow-up to my NHTSA complaint tracking #11742382, filed June 5, 2026, before my recall repair. I'm filing again because the repair is now complete and it has raised two new concerns: undocumented warranty coverage on the replacement engine, and an unresolved question about whether a second, broader recall applies to that replacement engine. 1. Recall repair completed. Under NHTSA Campaign 24V381000 (Toyota internal 24TA07, filed 2024-05-30), my original engine was replaced with a new OEM assembly (part 04004-23370, serial [XXX], 2026 manufacture date, incorporating the post-April-2024 revised bearing design) at Teton Toyota, Idaho Falls, ID, June 19 to 22, 2026 (repair order [XXX], mileage in/out 28,252/28,281). Toyota's own recall record states the replacement unit was inspected clean. I have no reason to doubt that specific finding; my concern is what happens after. 2. Replacement engine's warranty terms were left undocumented. The repair order lists the warranty "Policy Number" covering the new engine as TBD. As of this filing, Toyota National (1-800-331-4331) has not given me a written answer to a direct question: does the replacement engine carry a new 5-year/60,000-mile powertrain warranty starting from the June 22, 2026 install date, or only the remainder of my original factory warranty? A safety recall remedy that leaves the owner without documented knowledge of what protection they actually received is, in my view, an incomplete remedy under 49 CFR Part 573's recordkeeping and notification requirements. Owners should not have to chase this down themselves months after the repair. 3. A second, broader recall may or may not apply to my replacement engine, and Toyota has not said which. NHTSA Campaign 25V767000 (Toyota internal 25TA14, filed 2025-11-06) expands the same underlying defect population to additional 2022-2024 Tundra, Lexus LX, and 2024 Lexus GX vehicles, with a remedy of inspecting the #1 main bearing via inspection software and INFORMATION REDACTED PURSUANT TO THE FREEDOM OF I
NHTSA complaint #11762486 — an unverified report by a vehicle owner.
REPEATED CATASTROPHIC ENGINE FAILURE / FAILED RECALL REMEDY. My 2022 Toyota Tundra suffered a complete engine seizure and sudden loss of motive power August 30, 2026, creating an immediate traffic hazard. This is the SECOND time this vehicle has experienced a catastrophic main bearing failure of its twin-turbo V6 engine. The original factory engine was replaced by an authorized Toyota dealership under Safety Recall 24V-381 / 24TA07 in March 2025. The defect should have been resolved. However, the replacement crate engine provided by Toyota carried the exact same engineering vulnerability as the original engine. It was manufactured prior to Toyota's mid-2026 engineering revision, which finally introduced a redesigned #1 main bearing to address localized crankshaft pressure stack-up (as noted in subsequent NHTSA filings like 26V-320).Furthermore, the previous engine replacement due to a federal safety recall was entirely withheld and not disclosed to me at the point of sale. Because Toyota replaced a recalled, defective engine with an identically flawed engine block, the initial recall remedy completely failed, leaving the vehicle dangerous and prone to repeated mechanical failure. The vehicle has driven approximately 16 months since the March 2025 replacement. I am demanding that Toyota provide a permanent remedy using the updated, structurally revised 2026 engine components. It is at the Toyota dealer.

I was leaving work one day and pulled out in traffic and my engine stalled causing the car behind me to slam on their brakes to avoid crashing into me from the back my engine completely stalled and I got no gas to accelerate I then went to the dealership and stated what happened and they told me they could not help me at the moment so I wrote a letter to corporate Toyota and they put me in the loaner in the following week. I’ve been in the loaner for the past four months with no remedy on my truck and no answer to when it’s gonna be fixed or this problem is gonna be resolved.
NHTSA complaint #11761574 — an unverified report by a vehicle owner.
I am filing this complaint regarding my Toyota Tundra and Toyota Safety Recall 24TA07. My vehicle was previously affected by this engine recall, and Toyota replaced the engine as the recall remedy. The replacement engine has now failed with the same or substantially similar engine issue that resulted in the original recall and engine replacement. I am very concerned that a replacement engine installed as the remedy for a safety recall has experienced the same type of failure. This vehicle has now experienced engine failure involving two separate engines: the original recalled engine and the replacement engine installed by Toyota under Recall 24TA07. The Vehicle is at the Toyota dealer. I am requesting that NHTSA investigate whether replacement engines being installed under this recall may also be susceptible to the same or a similar defect. I would also like this complaint documented because I am concerned about the safety and reliability of the vehicle and whether Toyota's recall remedy adequately corrected the original safety issue. I am requesting that Toyota provide a permanent remedy for my vehicle at no cost to me. I would also like information regarding my rights and available remedies given that the engine replaced under the safety recall has now failed, including whether this repeat failure may qualify for additional manufacturer remedies or protections under applicable warranty or state lemon law.

ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM)
The contact owns a 2023 Toyota Tundra. The contact stated that while starting the vehicle, the check engine, Auto Start/Stop, and another unknown warning light illuminated. The message "Grill Shutter Malfunction Low Voltage" was displayed. The vehicle was taken to the dealer, who determined that the battery sensor, alternator, and ECU had short-circuited. The dealer replaced the battery sensor, alternator, and ECU; however, the failure persisted with the check engine and another unknown warning light illuminated. The vehicle was taken back to the dealer, who determined that the grill shutter needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 57,000.

Total engine failure in v35a at 65- 70 mph which dealer has confirmed was due to main bearing failure. Inability to accelerate vehicle in heavy traffic lead to extreme unsafe situation. No warning lamps came on until after the vehicle completed stopped running. Both the manufacturer and the NHTSA are well aware of the continued problems with these engines and the unsafe failure. The only warning ‘hybrid system malfunction “( which has nothing to do with dealer performed diagnostic of metal in oil pan failed main bearing) came on after the truck was inoperable.

"I am writing to report a latent safety concern regarding my 2022 Toyota Tundra Hybrid equipped with the V35A-FTS engine. Non-hybrid 2022–2024 Tundras sharing this exact V35A engine block architecture are subject to active safety recalls (NHTSA Campaign IDs: 24V381, 25V767, and 26V320) due to crankshaft main bearing failure caused by manufacturing debris and oil film disruption. My hybrid model utilizes the same V35A internal engine short-block assembly and suffers from the exact same potential for main bearing contamination and catastrophic internal engine lockup. Although the hybrid battery provides limited low-speed auxiliary power, a sudden internal combustion engine failure or lockup while operating at highway speeds or under heavy towing loads creates a severe safety hazard, including immediate loss of throttle response, power steering loss, and high risk of rear-end collisions. My engine has not failed yet, but the presence of known, unaddressed manufacturing debris within the V35A assembly presents an ongoing safety risk. I request that NHTSA expand its safety defect investigation into the V35A engine architecture to explicitly include the i-FORCE MAX Hybrid models." Toyota has been lacking in taking responsibility that these exact same engines manufactured on the same assembly line are also subject to the same issues. I believe it is a significant safety issue especially since in the event of an engine failure the hybid system will NOT be strong enough to move the vehicle to the side of the road safely. In addition, when the powertrain warranty expires next year for the 2022 models, owners will be left holding the bag for a $30,000 dollar engine replacement when toyota knows this could and has happened. Currently, Toyotas way of evaluating engines consist of hitting the engine with a hammer to check if its affected or not. What?? Please investigate this and hold toyota responsible, all engines manufactured on that assembly line in AL should be replaced.

2023 Toyota Tundra CrewMax SR5 4x4, VIN [XXX], approximately 79000 miles. This vehicle has two open safety recalls. Both show "Recall Incomplete, remedy not yet available" on NHTSA's VIN lookup as of XXX NHTSA 25V322 (Toyota 25TB06) was filed XXX for moisture intrusion causing both reverse lamps to fail. Toyota's remedy notice estimated that the remedy would begin to be available in the fourth quarter of 2025. That estimate is now approximately nine months past and no remedy is available for this VIN. NHTSA 25V767 (Toyota 25TB14) was filed XXX for machining debris causing number one main bearing failure, with symptoms including engine knocking, rough running, no-start, and loss of motive power. Interim notices were mailed XXX. The remedy has been postponed and remains unreleased for this VIN, with rollout phased by vehicle age. I am filing because the manufacturer has been unable to provide a remedy for either recall within a reasonable time. I have owned this vehicle since XXX and have been unable to obtain repair for a known safety defect for more than fifteen months on the first campaign. I am requesting that NHTSA record this delay and address the manufacture's remedy timeline. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

engine knocks on start up or is very rough. the truck only has 8200 miles on it. i’m waiting for the recall to be processed but it’s been 2 years and i’m still waiting. i want to sell the truck because im afraid of it breaking down when i need it. but no one wants to buy the truck based on issues with the engines Toyota put in the trucks. how long do i have to wait for a new engine with the same design flaw? why is this issue taking so long to be rectified.How long do i have to wait for the back up light s issue to be resolved also? that’s also been 2 years! who’s sleeping at the wheel here to put pressure on Toyota?
NHTSA complaint #11759511 — an unverified report by a vehicle owner.
My 2023 Toyota Tundra iForceMAX truck has been out of commission for 56 days (Since June 29, 2026). I have experienced a "shroud rub" issue which is a widely documented design flaw in 2022–2025 Tundras. It happens when pressure from the transmission lines warps the passenger-side plastic fan shroud, pushing it straight into the radiator fins until it rubs a hole right through them. The dealer (Fred Haas Toyota World, Spring TX) has stated that they are still waiting for a new fan shroud to arrive and have NO firm date when it will arrive. This is a safety issue as the vehicle sends a clear warning on the dashboard gauge cluster of the dangerous condition to over heating and advises the driver to immediately pull over, switch offthe engine and let it cool down or risk catastrophic failure.

I am 99% sure my vehicle is compromised via a cybersecurity incident. My emergency brake will sometimes slam for no reason, no multi media system updates have occurred for over two years, and the vehicle will randomly beep on its own, unlocking the doors. Another major issue is a recent electric harness failure that the mechanics have no idea how it happened. It cost me over 8,000. Warning lights also turn on for no apparent reason such as parking, sensors, and other traction control. I am extremely concerned with my safety. I also believe the odometer has been altered to register higher mileage.
NHTSA complaint #11758940 — an unverified report by a vehicle owner.
“Before purchasing the vehicle new, I specifically asked the selling dealership about the known engine-related stop-sale concerns affecting Toyota Tundras. I was advised that the applicable issue involving this vehicle had been addressed and that the truck had been cleared for sale. The vehicle was subsequently sold to me as new. At approximately 5,141 miles, an independent repair facility documented gold-colored shavings/material in the engine oil filter. The filter has been preserved. My VIN currently shows no unrepaired recall. I have formally notified Toyota Motor Sales and requested that Toyota identify what stop-sale, recall, inspection, remedy, or other corrective procedure was performed on this specific VIN before it was released for sale. The composition and source of the material have not yet been determined. I am concerned that, if the material represents abnormal internal engine wear, the condition could potentially result in engine failure and loss of motive power while driving.

Ive been waiting for years for the previous recalls I have been informed about to get fixed. Feul system,brake lights.Was told by Toyota that someone would call me to come to get them taken care of. In the meantime, constantly checking that my brake lights are working before departing on any excursions in truck & patiently waiting for toyota to reach out when they were gonna fix the first 2 recalls that I was notified about. I can't recall the date exactly, but I was driving on the highway w/ my still backward carseat, facing 2y.o. baby safely strapped in,ThankGod.As accelerating into my lane, heard huge BOOM like an IED. Immediately, the check engine light among others came on.Truck immediately lost power & was violently shaking.Felt it in the steering wheel, but largely in engine compartment.@this time,I tried to get over to shoulder to a safe place.I turned the car off.Let it rest checked on my infant in back made sure he was ok. After letting car rest, turn back on to my surprise All lights were off.I was w/in few miles of home so went directly back, never getting to my intended destination. Shortly before driveway, all lights came back on & multiple service messages.Since then the truck has not been driveable,As we have specifically looked up recalls,thusly Nov.recall matched lights on the dash for the specific make,year, model of truck. From my understanding, it says that there is no remedy for such recall. But that is untrue. The remedy is an entirely new engine. They just haven't rolled out the recall info to everyone applicable. I am unable to work. My home is without a vehicle and this is unacceptable.Along w/ safety risk to me and infant. I'm sure Toyota doesn't want to admit or remedy Because that is very costly. But this was a mistake made by the company. And it should be remedied, because our family is suffering in various ways. Lost revenue. Inability to respond if emergency etc.I need a new engine.& in the interim,I need a car supplied while fixed.

The contact owns a 2023 Toyota Tundra. The contact received notification of NHTSA Campaign Number: 25V767000 (Engine and Engine Cooling). The contact stated that while driving 40 MPH, there was white smoke coming from the exhaust pipe. The vehicle was taken to a dealer to be diagnosed, and the head gasket needed to be replaced. The vehicle was not repaired under the recall because there was sludge found inside the engine. The manufacturer was notified of the failure. The failure mileage was 70,000.
NHTSA complaint #11758060 — an unverified report by a vehicle owner.
-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 catastrophic engine failure has been confirmed by the Toyota Dealership. Th4ey Confirmed multiple shavings of metal in the entire oil system and the engine has seized. He said that the engine needed to be replaced. -The tundra has not been inspected by the manufacturer, police, insurance (yet) or others besides the Toyota dealership. -There were no warning lamps, messages, or other symptom of the pending catastrophic total engine failure.
