1 Engine And Engine Cooling problem

Failure Date: 08/25/2026

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?.

2 Engine And Engine Cooling problem

Failure Date: 08/24/2026

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.

3 Engine And Engine Cooling problem

Failure Date: 08/17/2026

“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.

6 Engine And Engine Cooling problem

Failure Date: 07/31/2026

July 31, 2026 driving on the garden state parkway in NJ in traffic at 65 mph in the far left lane, my engine seized without warning. The car started beeping and the dash lit up something like engine stopped low steering power. I had to maneuver across 2 lanes of high-speed traffic with no power, limited steering and brakes. Then coasted to a stop and tried to restart the engine. Only a click, nothing. After that I had to wait on the side of the highway for 20-30 minutes with cars speeding by only inches away so fast it shook the truck. One miscalculation by a driver could have resulted in a crash I was towed to my house, then towed to Toyota dealer. They confirmed my engined seized due to recall 25tb14 safety recall - 25ta14 (interim notice 25tb14) and replaced the engine. Vehicle had 22,3xx miles when it failed and was less than 2 years old.

7 Engine And Engine Cooling problem

Failure Date: 07/27/2026

My 2024 Tundra with 55000 miles suddenly lost all power going down a major highway. The engine failed suddenly. Luckily I didn’t wreck. I paid out of pocket to have it towed to dealership where it has sat untouched for 9 days. The engine is included in the recall that they have.

8 Engine And Engine Cooling problem

Failure Date: 07/07/2026

5/4/26 truck brough in for service, I raised concerns of hesitation from a rolling stop/complete stop. This hesitation had happened to me a dozen or so times since purchasing the truck new in August of 2024. I expressed to my service advisor that I experience a 2-3 second delay in acceleration with the truck simply not responding after I have pulled out in traffic from a rolling stop. My service advisor noted my concern and got with the service manager. The service manager took the time to ride along with me in hopes of duplicating the problem. We were not able to reproduce the hesitation. Inconclusive findings was my conclusion of that service. T-sb-0032-26 was issued two days later on 5/6/26 7/3/26 truck brought in for service, I shared with my service advisor that I discovered t-sb-0032-26 while reiterating my previous experiences. TSB was performed on the truck successfully according to my service conclusion report. 7/7/26 hesitation almost caused an accident. As I was crossing two way traffic, the truck hesitated. Traffic in both directions had to apply their brakes to avoid hitting me. This 2-3 second hesitation in acceleration creates a very unsettling moment. This is the kind of hesitation that could easily result in my getting rear-ended or t-boned in traffic. Other cars have to react to my truck not responding and slow down. If this causes an accident, I want this noted. I sent this information to my service advisor, the truck is going back to Toyota tonight for them to look into the computers history and see if they can find anything showing the hesitation. I even noted the date and time to my service advisor. Very interested to see what they do next.

9 Engine And Engine Cooling problem

Failure Date: 07/06/2026

I own a 2024 Toyota Tundra 1794 edition with approximately 37,000 miles. On or about xxx, while driving, the vehicle displayed a “check engine” warning, “reduced engine power” message, and the pre-collision system became disabled. The vehicle immediately became sluggish and lost power during acceleration. The loss of power created a safety concern because the truck was unable to accelerate normally when entering and crossing intersections. I did not feel safe continuing to drive the vehicle, especially while transporting my 9-year-old daughter. Due to the safety risk, I parked the vehicle and have not driven it since the warning first occurred. The warning lights remain active. The vehicle has not yet been inspected by a Toyota dealer because I do not believe it is safe to drive to the dealership. I am requesting dealer evaluation and towing assistance. The component that failed is currently unknown. The vehicle is displaying a check engine light and reduced engine power condition. The condition can be inspected and diagnosed by Toyota. No crash, injury, or property damage occurred because I immediately stopped using the vehicle once the safety concern became apparent. I am submitting this complaint because a sudden reduction in engine power while driving creates a significant traffic safety hazard.

10 Engine And Engine Cooling problem

Failure Date: 07/03/2026

While driving my 2024 Toyota Tundra, the check engine light illuminated and the vehicle suddenly experienced reduced engine power. I safely pulled over, shut the engine off, and restarted it. After restarting, the vehicle appeared to operate normally, but a diagnostic scan showed dtc p0300 (random/multiple cylinder misfire). On July 20, 2026, I brought the vehicle to an authorized Toyota dealer for inspection. During the inspection, the dealer found significant metal shavings in the engine oil, indicating a possible internal engine failure. Based on these findings, the dealer instructed me not to drive the vehicle and retained it at the dealership because they considered it unsafe to operate. My vehicle is already included in Toyota’s engine recall related to engine manufacturing defects. However, despite the dealer confirming the presence of significant metal shavings and advising that the vehicle should not be driven, no repair or resolution has been provided. The dealer has been unable to provide an estimated repair timeline or when the vehicle will be returned to service. The vehicle is available for inspection. No crash or injuries occurred. Prior to the incident, there were no warning signs or abnormal symptoms. The check engine light and reduced engine power occurred suddenly while driving. The unexpected loss of engine power created a significant safety risk, particularly while driving at highway speeds or in traffic. I am also concerned that an apparent internal engine failure occurred with little or no warning. In addition, because the dealer has retained the vehicle and no rental or alternate transportation has been provided, I have been left without transportation while waiting for a resolution.

11 Engine And Engine Cooling problem

Failure Date: 07/02/2026

Complete catastrophic engine failure at 36,514 miles on July 2, 2026, while the vehicle was being driven. There were no warning lamps, messages, knocking, or other symptoms prior to the failure - a sudden and total loss of motive power while the vehicle was in motion, creating a serious risk of a crash. The vehicle was towed to a franchised Toyota dealership (hendrick Toyota concord, concord, nc), where the dealer confirmed the engine failure. The failure is consistent with the engine machining debris / #1 main bearing defect described in NHTSA recall nos. 24v-381 and 25v-767 and the related Toyota campaigns (25tb14/25ta14). As of this filing, the vehicle has been out of service at the dealership for more than 40 days with no replacement engine allocated and no repair date provided. A Toyota corporate case (#260805003088) is open. The vehicle and failed engine are available for inspection at the dealership.

12 Engine And Engine Cooling problem

Failure Date: 06/30/2026

This is the second time this has happened to my truck. I was driving on the freeway at about 30–40 mph when the truck suddenly shut off. It was very scary because I was in moving traffic. This time, several warning lights came on, but I didn’t have a chance to see what they were because I immediately started to panic. I had to bring the truck to a complete stop by applying the brakes and then shifting it into park. Once I did that, I pressed the start button, and the truck started back up. This incident has me very concerned because it’s now happened twice. I’m worried that if it happens again, I could be rear-ended and seriously injured. I believe this is a significant safety issue that needs to be investigated and repaired as soon as possible. This is the second time this has happened to my truck.

13 Engine And Engine Cooling problem

Failure Date: 06/21/2026

When returning home from vacation towing my travel trailer. A warning light came on that said pull over immediately you have lost all power. I pulled over immediately and definitely had lost power and was stuck on a mountain pass. I called for a tow which took 7 hours. I called Toyota during that time and they couldn't tow me home just to the nearest dealer. My family and I had to wait for 7 hours on a small turnout on the road it was very hot that day. I had my truck towed to my local Toyota dealer and they confirmed it was the engine with metal shavings in the oil pan. Towing costs were 1102. 50 out of my pocket as Toyota would not cover.

14 Engine And Engine Cooling problem

Failure Date: 06/16/2026

Vehicle has two open Toyota safety recalls that have remained unresolved for over a year. Nhtsa campaign 25v322 (manufacturer no. 25tb06) covers reverse lamp assembly corrosion. Nhtsa campaign 25v767 (manufacturer no. 25tb14) covers a v35a engine manufacturing defect where leftover machining debris can damage the main bearing, leading to engine knocking, rough running, no-start, or loss of drive power while driving. No engine symptoms have occurred to date. However, the vehicle is used for rideshare and delivery work, meaning passengers and cargo are regularly on board while this known defect remains unremedied. The dealership stated it could not address the engine recall and directed me to Toyota corporate. Toyota corporate opened a case and confirmed no remedy is currently available for this recall. The vehicle has not been inspected by the dealer or manufacturer, as no repair or inspection procedure has yet been provided to perform one. No warning lamps or dashboard messages have been observed. Vehicle is available for inspection upon request. Concern: a known crash-risk engine defect (loss of drive power) has been acknowledged by the manufacturer for over a year with still no completed remedy, while the vehicle continues to be operated commercially with passengers.

15 Engine And Engine Cooling problem

Failure Date: 06/09/2026

Vehicle surges sometimes and repeatedly from a stop, with delayed acceleration; very dangerous when merging or moving from a stopped position into a flow of traffic (such as turning right on red). Vehicle sometimes will not move at all under acceleration, as if it has no gas at all. Vehicle is under recall for both of these issues related to the engine, but "no remedy available. " latest incident of surging was less than a week ago. Happens 2-3 times a day on average. Vehicle will occasionally randomly run rough at stoplights / idle speed. I have contacted Toyota regarding a buyback and they stated they "could not offer a buyback because they have not had adequate chances to fix the problem. " so they have told me they cannot fix the problem, but won't buy back the truck because they have not had a chance to fix the problem (that they cannot fix). They have since stonewalled me and no longer respond to communications.

16 Engine And Engine Cooling problem

Failure Date: 06/07/2026

While traveling on us highway 95 between lewiston and riggins, idaho, a 2024 Toyota Tundra trd pro with approximately 18,000 miles experienced a sudden loss of engine power while descending a mountain grade with multiple curves. The driver reported hearing abnormal engine noises immediately before the loss of power. At the same time, the brake pedal became extremely hard to depress and the vehicle did not decelerate as expected, requiring substantially increased braking effort. The vehicle was carrying family members and was traveling on a winding downhill section of highway adjacent to steep terrain. Due to the loss of power and increased braking effort, the occupants feared the vehicle would be unable to stop safely. Fortunately, a roadside pullout area was available, and the driver was able to steer the vehicle into the pullout and bring it to a stop without a collision. The vehicle was towed to an authorized Toyota dealership for inspection. The dealership diagnosed the vehicle with a catastrophic engine failure requiring engine replacement. The failed engine remains in the possession of the dealership and should be available for inspection. Approximately five days before this incident, the vehicle had undergone routine maintenance, including an oil change and inspection at a Toyota dealership. The vehicle had also previously been presented for brake pulsation concerns and other drivability-related complaints. The vehicle was returned to service and represented as operating normally. No collision occurred and no physical injuries were reported; however, the incident created a significant safety risk because the loss of engine power occurred while descending a mountain highway and the driver experienced substantially increased braking effort while attempting to stop the vehicle.

17 Engine And Engine Cooling problem

Failure Date: 06/05/2026

The engine lost power and shut down at highway speeds which put myself and a passenger at risk for a crash. There were no warning lights or other symptoms before the engine shut down. After pulling the vehicle over to the side of the road, I attempted to restart the engine. The engine failed to turn over and start. The truck towed into a local dealership and is waiting inspection.

18 Engine And Engine Cooling problem

Failure Date: 06/04/2026

Engine shutdown while driving (was towing a travel trailer at the time) and after coasting to a stop the engine would not start. After 10 minutes the engine would start, but had loud knocking. My 2024 Tundra only had 31,726 miles and had to be towed to the dealership. Seems to be the known engine issues with the redesigned v6 engine. Tundra has been in the dealership for 4 weeks and was told it will require engine replacement, but do not know when the new engine will be shipped. While Toyota will perform the replacement free of charge, based on the hundreds of thousands of Tundra's being recalled for this very issue, I no longer trust this engine design (replaced or not).

19 Engine And Engine Cooling problem

Failure Date: 06/04/2026

I have a 2024 hybrid Toyota Tundra equipped with v35-a- fts 3. 4 l twin- turbo v6. This motor is the same engine as the non hybrid motors included in the recall. There was recently a defect information report sent out on may 20th 2026 from Toyota stating that there is an issue with the main #1 bearing and the newer motors are now being installed with upgraded new bearing indicating that all motors, hybrid or non hybrid prior to August of 2024 have this defect that could cause engine failure. The only reason this motor is not included in recall is Toyota saying that it not a safety issue because of the electrical motor is sufficient to get it off the road. I tow a boat and various trailers and feel like at highway speeds in traffic a failure of the main engine, with very limited assistance from electrical motor could cause a potential serious crash leading to serious injury or death. I am filing this to ask NHTSA to do the right thing and have Toyota to expand the recall and include the hybrids as it will only be a matter of time before before something will happen.

20 Engine And Engine Cooling problem

Failure Date: 06/03/2026

2024 Toyota Tundra experienced a serious safety event. While travelling on the highway at 60mph speeds in traffic when the truck suddenly blinked a loss of steering warning light then immediately blinked engine failure warning light. The truck lost power and the engine completely shut down in traffic going down a long, steep hill. I was able to reach the bottom and pull over but the truck would not restart. I had to have the truck towed to a Toyota dealership near my home.

21 Engine And Engine Cooling problem

Failure Date: 05/26/2026

I have a 2024 hybrid Toyota Tundra which shares the same engine that has undergone a NHTSA recall. I do not believe that the defect has been satisfactorily addressed to mitigate the risk of catastrophic engine failure in the v6 engine. I would like the recall to include the hybrid models as well for this well known and documented engine failure risk. I have not yet had any problems with the engine yet and am addressing the other separate recalls for this model. From a safety and liability perspective, I feel that Toyota has an obligation to provide the same warranty extension assurance and if needed, engine replacement as the gasoline only variant.

22 Engine And Engine Cooling problem

Failure Date: 05/26/2026

I was driving on the freeway in my Toyota Tundra when it suddenly shut off completely. It was honestly terrifying because my first thought was getting rear-ended in traffic. After about 15 seconds, the truck randomly turned back on by itself, but the whole situation really shook me up. A vehicle that new shouldn’t be doing something that dangerous.

23 Engine And Engine Cooling problem

Failure Date: 05/26/2026

The contact owns a 2024 Toyota Tundra. The contact received notification of NHTSA campaign number: 25v322000 (exterior lighting) and 25v767000 (engine and engine cooling) however, the part to do the recall repair was not yet available. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the issue. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure.

24 Engine And Engine Cooling problem

Failure Date: 05/25/2026

I have only owned the truck since mid April of 2026. The truck has 12000 miles on it. I have only put 200 miles on the truck. . . 150 miles are driving to the dealership. Engine recall notification was sent out last week of may 2026. Still an open recall for reverse lights with no remedy. Took Tundra into dealer at the beginning of may 2026 to get two other "electronic/infotainment" system recalls repaired. I bought the truck used from a dealership. Had three open recalls (electronic x's 2 and reverse light). Got two of three fixed. A few weeks later I get the engine recall. Really Toyota. . . I took the truck to maplewood Toyota on 5/28/26. There it sits waiting for repairs. I asked about getting out of the truck and my option was trade it in at kbb value ($45k-ish) I paid $57k and $3k for extended warranty for a total of $60k. I am not going to eat $15k on trading in the truck. Toyota should stop selling vehicles with these engines now! these engines should not be on the road or being sold - period. Toyota still using the "debris" in engine from manufacturing in 2024 is criminal. We are talking about the debris issue in 2022, 2023, 2024 engines. . . . This is outright criminal. Shame on you Toyota. I am a Toyota buyer. I own a 2019 corolla. My friends and family are also Toyota owners. This v35a engine is a complete failure and production should be stopped. I kick myself for not doing more research before buying the truck. I never would have purchased knowing the ongoing engine issues. Dumb me - I am buying a Toyota because I trust there is no reason to worry - boy was I wrong. Please hold Toyota accountable for this. Toyota should buy back every vehicle that has this engine if the owners want that option. Anyone with a 2022 - 2026 v35a engine - drive at your own and everyone else on the road - risk.

25 Engine And Engine Cooling problem

Failure Date: 05/20/2026

I am filing this complaint regarding an active safety recall on my 2024 Toyota Tundra involving manufacturing debris left in the v35a 3. 4l twin-turbocharged v6 engine during production. This recall has been open for multiple years and spans over 250,000 vehicles across the 2022–2024 Tundra, Lexus lx 600, and 2024 Lexus GX 550. The manufacturing debris causes damage to the engine’s main bearings, resulting in engine knocking, rough running, failure to start, and sudden loss of motive power while driving at speed — a condition Toyota itself acknowledges increases the risk of a crash. Toyota deployed a remedy consisting of full engine replacement; however, Toyota has since acknowledged that the replacement engines are experiencing the same failures, meaning there is currently no confirmed, working fix. Despite this, Toyota continued selling new vehicles with this known defect. Remedy deadlines have been repeatedly promised and repeatedly missed, with the latest expected resolution pushed to July/August 2026 — a deadline that has already slipped multiple times. As an owner, I am left driving a vehicle that Toyota acknowledges is dangerous, with no confirmed timeline for a legitimate repair, and suffering significant financial harm due to the ongoing depreciation and diminished resale value caused directly by this unresolved defect.

26 Engine And Engine Cooling problem

Failure Date: 05/20/2026

Toyota issued a recall (NHTSA 25v322) over a year ago. We are now more than a year beyond the issuance date of this recall and stop sale order for affected vehicles. There is still no remedy available for this recall and from what I can tell, none in sight. Additionally, on 11/6/25, Toyota issued a recall (NHTSA 25v767) related to potential engine failure. Over 6 months after this recall and stop sale notice there is no remedy available. Both of these issues go beyond what most would consider remedying the issues in a “timely manner”.

27 Engine And Engine Cooling problem

Failure Date: 05/16/2026

While driving to dinner in bluefield< west virginia on Saturday evening, I came to an intersection where I was making a left hand turn with a green arrow on the light. As I approached the intersection, I slowed to something under 10 miles an hour and proceeded to initiate a left hand turn. As I rolled onto the throttle, there was no response from the engine for approximately 15 seconds. The engine remained at idle as I coasted through the turn. I continued applying throttle with no response until I reached approximately 50% of throttle pedal travel, at which time the engine sputtered then accelerated rapidly. This is not the first instance of this issue. It has happened on at least 4 different occasions in the past. The issue is intermittent and could easily result in an accident if it occurs while pulling out into traffic - which is what happened the first time it happened to me with the oncoming traffic being forced to take evasive action.

28 Engine And Engine Cooling problem

Failure Date: 05/05/2026

I was on the highway driving about 70 mph, when the engine suddenly turned off. The lights on the dashboard stated that I needed to pull over immediately. The truck was towed to a dealership who confirmed the engine was "destroyed" due to safety recall 25ta14.

29 Engine And Engine Cooling problem

Failure Date: 05/03/2026

While driving, the vehicle unexpectedly stalled and lost power. The vehicle was taken to an authorized dealership for diagnosis, where the same stalling condition was reproduced and confirmed during a dealer road test. The vehicle had to be towed back to the dealership, where the engine was found to be seized. The sudden loss of power while driving created a serious safety concern because the vehicle could become disabled without warning and lose motive power in traffic. The failure was confirmed by the authorized dealership, and the vehicle and engine were available for inspection during the repair process. There were no known warning lamps, diagnostic messages, or other clear advance warnings that would have allowed me to anticipate the engine failure before the vehicle stalled.

Paramedics arrived to try and direct traffic. The truck had to be towed to the dealership and they verrified that the engine siezed.

32 Engine And Engine Cooling problem

Failure Date: 04/30/2026

Ubject: urgent safety incident report: engine seizure at highway speeds – case #xxx to the Toyota safety & compliance department: I am writing to formally report a critical safety incident involving my 2024 Toyota Tundra (VIN: [xxx] ). Incident description: while traveling at highway speeds, the vehicle’s engine suffered a catastrophic internal seizure and shut down completely without any prior warning. This resulted in an immediate loss of motive power in the middle of high-speed traffic. Because the engine died, I also experienced an immediate loss of power steering assist and power brake vacuum, making the vehicle extremely difficult to control. I was forced to perform an emergency maneuver to avoid a rear-end collision and struggled to steer the truck toward the shoulder while other vehicles swerved around me at high speeds. Safety hazard & manufacturing defect: this failure is identical to the conditions described in NHTSA safety recall 24v-381 (Toyota recall 25ta14). The dealership's diagnosis at autonation Toyota weston confirmed that the bearings are discolored and "spun," which is a direct consequence of the manufacturing debris that Toyota has already admitted exists in these engine blocks. Bad-faith warranty denial: despite the life-threatening nature of this event, the dealership is attempting to blame "abuse" based on a software log from the brake override system. They are ignoring the fact that a metallurgical failure of the main bearings has no mechanical link to pedal input. Using a safety software record to deny a repair for a known manufacturing defect that nearly caused a fatal accident on the highway is unacceptable. Requested action: I demand that this case be immediately reviewed by Toyota’s safety team. My vehicle manifested the exact defect described in the federal recall during a high-risk situation. I am requesting an immediate resolution to remove this dangerous vehicle from the road and to honor the terms of the information redacted pursuant to the freedom of information act (fo.

34 Engine And Engine Cooling problem

Failure Date: 04/26/2026

While driving, I noticed that the vehicle seemed sluggish. Shortly after, I experienced grinding and knocking. The engine then stalled when I came to a traffic light. Fearing for my safety, I was able to get the engine to re-start to be able to pull off the road into a parking lot. At this point, the engine was barely running and making a ton of noise. There were no warning lights prior or after the incident took place. The vehicle was towed to my local Toyota dealership who performed an inspection and determined that the short block needs to be replaced, despite the contamination risk of other components. I have demanded that Toyota replace the engine with a complete new assembly, however, they are declining to do so.

35 Engine And Engine Cooling problem

Failure Date: 04/22/2026

First engine has not failed yet, it will happen. It presents a safety defect potential stalling , engine failure, or worse. . . . It is same engine as non-hybrids . Build date December 2023. Cuurent milage 23k . Toyota excluded hybrids with no proof safely exit hwy under electric power. I avoid passing lane for this very reason. Hybrid cannot gain speed to get over to side of the road. With drastic loss of speed . Even more dangerous if pulling trailer. Sumitt November 6, 2025 defect information report Toyota sent to NHTSA . Section no 6 I find very interesting and disturbing. While Toyota voluntary did recall , the report indicated engine failure not from debris but main bearing failure defects. Grenade waiting to happen. Hybrid owners with false safety from Toyota that can get over is a very dangerous message. Same defect engine exact as ones under recall. They are currently being sued over this. Nhtsa must take action to include same defect engine in the hybrids. Also putting link to a video of a tear down where took nearly 3 years get a blown engine for teardown. I see why now. 2026 engine has fixed main bearings with more oil pathways. If it was ever a debris issue , Toyota would have never fixed defect main bearings and more oil pathways. Fixwd 2026 engine going into recall. November 6, 2025 defect information report shows that main bearing failure.
