Power Train Problems of Toyota Tundra - part 1

I have not had an actual vehicle accident as of yet but the vehicle has a serious hesitation issue during acceleration from a quick stop or rolling situation whereas if you were making a left turn at a traffic light and were waiting for traffic while execrating to clear the next on coming vehicle there is sometimes a 3 second or more delay before the vehicle will accelerate which could cause an accident. Toyota has recognized this issue and came out with a technical service bulletin (t-sb-0032-26) with an update program for the tcu but has not included my VIN or several others that have this same issue. I have been told by my dealer that they could do the update but since my VIN is not included they would have to charge me. This is a major safety issue and needs to be addressed at no cost to the consumers. I have contacted Toyota brand engagement and they were no help at all acting like they had no idea what I was talking about. It happens every, everywhere. Major safety issue. Making complaints before accidents or fatalities happen because of this!.

I've been experiencing throttle lag on my 2022 Tundra in certain situations during rolling stops (I've also had it occur from a dead stop, though more frequent in rolling stops). Sometimes there is a significant delay in throttle response, and the other day while pulling out into traffic the delay was perhaps 2-3 seconds. This nearly created an accident as the engine had zero response and greatly affected my ability to accelerate quickly enough. Please consider this as a possible recall, as the danger level is very high for this known issue. Thank you for your time.

Third recall - just issued may 20, 2026 NHTSA campaign 26v320000 43,566 additional vehicles (2024 Tundras including mine) brings total recalled to 272,566+ vehicles remedy status: "currently under development" two years and three recalls later, Toyota still has no proven fix the pattern: first recall (24v-381) - may 2024: 102,000 vehicles (2022-2023) second recall (25v-767) - November 2025: 127,000 vehicles (added 2024s built after Toyota claimed fix) third recall (26v-320) - may 2026: 43,566 more vehicles, still no remedy Toyota is slow-rolling the true scope while claiming each time they've "identified all affected vehicles. " my oil analysis - objective evidence of bearing damage blackstone labs analysis at 5,500 miles (July 2024): at just 5,500 miles, my engine was already showing 3-6x elevated bearing wear. Significance: this was done before any recall was announced for my truck (independent documentation of defect) proves debris causes measurable damage even at very low mileage I'm now at 15,000+ miles approaching the 20k-30k failure range Toyota has provided zero guidance about damage progression attached: full blackstone labs report Toyota's smoking gun admission before I did this oil analysis, I called Toyota customer service to ask if my 2024 truck was affected in the first traunch of recalls. They told me my vehicle was manufactured 5 months after the issue was discovered and that my truck was not affected. Then in December of 2025 a second recall and now mine is in that recall. Toyota admits they discovered the contamination problem, then continued building engines with the same defect for at least 5 more months before my truck was built. This wasn't an oversight—this was deliberate production and sale of defective engines while publicly claiming the issue was due to machining material left in the block.

Gas pedal hesitation at a rolling stop. There is a delay in acceleration during occasional rolling stops at locations such as yield signs and unmarked intersections on the roadway. When this happens the driver may depress the accelerator more than should be necessary causing tire spin and traction control integration. The traction control drastically reduces speed and limits acceleration which is a detriment to any oncoming traffic and everone else on the road. Many owners acknowledge this issue on social media. No warning lights. Toyota has a service bullitin out for this as of may 2026, but has limited VIN numbers they will update for free. My truck has been an issue since purchased new in March 2023. It can be an intermittent issue and the dealer can't seam to duplicate it on inspection. Since they couldn't duplicate it the first time I complained about it, they want to charge for diagnosis. Toyota will not update the transmission module because my VIN number isn't included and they can't duplicate it. This is a safety issue and all VIN numbers should get the software update in my opinion. Tsb0032-26 is Toyotas service bulitin. Toyota told me they would only do it if it was a safety recall.

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 issue I’m having is the transmission/engine when it comes to the hesitation for stopping and either slowing down or just a rolling stop. Sometime I would feel like I need to precisely control the brake pedal in order to go smooth stop, but no. It feels like it’s ’jumping’ in Mini burst. I have the hybrid engine of the v35a-fts. I did check for recalls but nothing found but found a TSB from Toyota t-sb-0032-26, but my hybrid is not covered, only the non-hybrid Tundra. Please help. Thanks.

When the vehicle comes to a complete stop or is slowing into a stop, there is a delay of power often followed by too much power causing the vehicle to launch forward. It happens most of the time and could be potentially very dangerous. There are times when the vehicle is needed to go now, not a second or two from now, and that delay has caused a few near miss. The issue has been on going since I got the vehicle new, but didn’t know I could report it here.

I was crossing two lanes of a 4-lane highway from a stop. I floored the accelerator to cross traffic and the truck hesitated for approximately 1-2 seconds in the middle of the highway before finally accelerating. During this time I was completely exposed to oncoming traffic with no ability to move the vehicle. This is not the first time I have experienced throttle hesitation on this vehicle but this was by far the most dangerous instance. The truck has ~17,000 miles and is a 2025 model year.

Multiple times in my almost 3 year ownership I have experienced a “dead pedal” while pulling out into traffic from a stop. It has almost caused a t bone accident on a few occasions. It’s been to the dealer and had a software update TSB 0111-22. After the update I didn’t have the issue for a little while, but it has come back and it now happens almost every time I drive it. Online search shows that there are multiple people having this problem. Toyota needs to come up with a fix for this before it causes a bad accident.

The contact owns a 2025 Toyota Tundra. The contact stated that after driving from a complete stop, the vehicle hesitated to accelerate while the accelerator pedal was depressed. There was no warning light illuminated. The vehicle was dealer, who was unable to duplicate the failure. The vehicle was not repaired. The contact related the failure to technical service bulletin: 0111-22 (hesitation from stop and surge concerns ); however, the year and vehicle were not covered under the TSB. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA hotline. The failure mileage was approximately 2,700.

2024 Toyota Tundra 4x4 sr5 crewmax 6. 5, VIN: [xxx] , 28,500 miles. Three distinct, worsening vibration issues affecting separate systems: 1 — powertrain/driveline: significant vibration on initial acceleration, under tow load, and on inclines. Suspected driveshaft carrier bearing, u-joint, or engine main bearing failure. Recall 25v-767 (v35a engine bearing debris, 2022–2024 Tundra) — VIN recall status to be confirmed at [xxx] . Component available for inspection. 2 — highway vibration 40–70 mph: constant speed-dependent vibration in steering wheel, seat, and floor. Worsening and expanding in speed range over time. Impairs steering feedback — direct safety hazard at highway speed. Suspected wheel bearing or hub failure. No warning lamps present at any time. 3 — braking: violent vibration during heavy deceleration, downhill braking, and rapid stops. Severely impairs controlled stopping and risks loss of vehicle control. Consistent with rotor degradation per Toyota TSB (Nov. 2025, 2022–2026 Tundra). Repair history: oem tires replaced at 20,000 miles — abnormal camber-induced outside shoulder wear. Toyota issued a limited service campaign for this identical defect on 2022–2023 models but explicitly excluded 2024. All 4 tires replaced twice. Multiple alignments, balancings, and rotations performed at l&s Toyota, beckley, wv (3+ dealer visits) and an independent tire chain (3+ visits). No resolution. Defect is mechanical, not tire-related. No dtcs or warning lights at any visit. Safety risk: braking vibration risks loss of control on downgrades and emergency stops. Highway vibration impairs steering feedback over extended driving. Towing vibration creates trailer instability on public roads. Requesting NHTSA investigate and include 2024 Tundra in the existing limited service campaign covering this known defect on prior model years.

Approaching a round about at a slow rate of speed, prior to entering I noticed there was time to safely enter the round about ahead of a car also entering the roundabout from another direction. I pushed the accelerator pedal to about 30% at the time I choose to enter the traffic circle and attempted to enter. The truck did nothing in response except keep rolling forward due to the momentum I already had while approaching the round about / traffic circle. After about 2 seconds, I pressed the pedal to about 70%. This still did nothing for about another 1 second, before the truck accelerated as if I had pressed the pedal to 70% from a stop. Fast acceleration into the round about which caused a narrow miss between me and the original car mentioned that was also entering the traffic circle.

Very commonly when the truck is “cold” after sitting overnight, the truck fails to accelerate from a stop while pushing the accelerator pedal down gradually (such as when leaving a stop sign at an intersection. This lack of acceleration makes me feel a loss of control as I cannot get the truck to accelerate. For example, driving out of my neighborhood into oncoming road traffic I feel as if the truck doesn’t sense my pedal input. The truck just “floats” for at least a few seconds before the pedal reaches a point where the truck recognizes the input and activates acceleration. I can see this situation causing a safety hazard such as when trying to gain speed from a stop. The dealerships says it’s a non-issue and normal for a turbo-charged engine. I have owned cars with turbo-charged engines and have never experienced this bad of lag before. I don’t feel this is normal. My truck currently has no engine issues and is maintained routinely.

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.

I live in a city with many roundabouts for intersections. These do not require a full stop, rather a yield and go. I often encounter throttle lag when I roll into the roundabout and need to accelerate to fit a gap in traffic. This lag results in the inability of a continuous flow of traffic because my vehicle simply does not respond to the accelerator.

The issue is a dangerous hesitation during low-speed rolling acceleration. In real-world driving, when I slow down but do not come to a full stop — such as when merging, changing lanes, entering traffic, crossing an intersection, or rolling through a turn — the gasoline engine can shut off while the truck is still moving. When I then press the accelerator to re-enter traffic or move quickly out of the way, there is a noticeable delay before meaningful propulsion is delivered. This hesitation is not a minor comfort issue. It creates a real safety risk. In a small hybrid passenger car, electric-only rolling behavior may be acceptable because the electric motor can often move the vehicle adequately on its own. But this is a full-size half-ton pickup. In my experience, the electric motor alone does not always provide sufficient immediate response for the weight and use case of the vehicle. The result is a dangerous dead zone where the driver is asking for acceleration, the vehicle is rolling, traffic conditions are changing, and the truck does not respond quickly enough. If a Toyota hybrid half-ton pickup is moving, the gasoline engine should not shut down in a way that prevents immediate acceleration when the driver presses the accelerator. This behavior has created multiple close calls for me. The most concerning scenario is a rolling slowdown followed by the need for immediate acceleration — for example, pulling into traffic, changing lanes, or clearing an intersection. In those moments, a 2–4 second delay is not merely annoying. It can be the difference between safely completing a maneuver and being exposed to a collision.

It is unknown exactly what causes the issue. But intermittently when taking off from a stop, the powertrain hesitates to respond to my input on the throttle. The hesitation lasts anywhere from half a second to a full second. This puts my safety and other driver’s safety at risk because I cannot reliably tell whether I will be able to pull out quickly and safely in front of an oncoming vehicle. The problem has not been reproduced by a dealer on my particular vehicle. There has been no inspection. There are no warning lamps, messages, or other symptoms. This issue has happened since the truck had only 9,500 miles on it.

I own a 2025 Toyota Tundra sr5 non-hybrid. The vehicle has transmission hesitation/delayed throttle response after a rolling stop. When I slow down but do not come to a complete stop, then press the accelerator again, the truck sometimes has a 1–2 second delay before it responds and begins moving/accelerating. After the delay, acceleration can come in suddenly, which makes the vehicle feel unpredictable and dangerous. This happens in normal driving situations such as rolling through turns, slowing for traffic, approaching intersections, or merging into traffic. The delay creates a potential safety concern because the vehicle does not respond immediately when throttle input is applied, which could increase the risk of being hit by cross traffic or not being able to accelerate as expected. I had two close calls so far where the vehicle wouldn't accelerate through a cross traffic intersection. The issue is intermittent but repeatable and has occurred at least a dozen times over my one year ownership (purchased brand-new in March 2025). There are no warning lights present on the dash. The issues started to be apparent almost immediately and has been continuing. During a 5k mile service visit at bobby rahal Toyota in mechanicsburg, PA, I explained my concern to a service advisor, and they advised me that Toyota is aware of this problem but there is not fix for it. This was approximately 6 months ago. As of today, March 30, there is still no fix for this issues that I am aware of.

Dead pedal incidents. At least 4 times in the 6months of ownership, I've experienced where when you press on the gas to go, there is no acceleration for approx 2 seconds. Its almost caused an accident 2x of the 4x times its happened. I feel it may be related to the transmission. Prior to this truck I had a 22' Lexus ls500 fsport which I think also has the 10 speed trans and twice experienced similar conditions. It kind of feels like the trans is slow in downshifting, trying to figure out where it needs to be.

The vehicle experiences hesitation when starting to move from a stop. So if I come to a stop and pull out into traffic it sometimes hesitates before applying the throttle that has been input via the pedal. This could cause serious injury because its almost impossible to determine when its safe to pull out into traffic because you do not know how long it will take for throttle to kick in.

I am seeking a case review regarding a persistent and unresolved drivetrain issue with my 2025 Toyota Tundra (non-hybrid) that began immediately following a dealership service visit and has continued for over one month without resolution despite multiple repair attempts. Since that time, the vehicle has exhibited consistent transmission-related defects including failure to shift properly into higher gears (notably not reaching 10th gear at highway speeds), rpm hanging under light throttle, delayed acceleration followed by sudden surges in power, and harsh or erratic downshifting that causes the vehicle to lurch forward when slowing to a stop. The vehicle also demonstrates inconsistent torque delivery, where boost builds but power is not transferred until a delayed and abrupt engagement occurs. These issues are most pronounced during normal highway driving conditions and significantly impair drivability and safety, particularly when merging or maintaining speed. I have brought the vehicle to multiple Toyota dealerships for inspection, where diagnostic scans have not produced any fault codes and I have repeatedly been told the vehicle is operating “within normal parameters,” despite the ongoing and reproducible performance issues. The dealerships have been unable to replicate or resolve the problem, and I have received inconsistent explanations ranging from normal operation to speculative driving pattern causes. I have an active case open with Toyota corporate, but after a month of delays, lack of diagnosis, and no corrective action, the issue remains unresolved. Given the ongoing safety concerns, repeated repair attempts, and inability of Toyota to identify or fix the defect, I am now left without a resolution & am instructed to drive the vehicle despite drivetrain issues.

The same thing that I reported in incident number xxx happened again recently. From a stop. I went to make a right turn on red in a four way intersection. The oncoming traffic to my left was also stopped. When I started to proceed the truck felt like it was in like 5th gear, moving barely but no real power, then it dropped into what felt like 1st gear and lurched me forward. I almost hit a car to my right that was stopped and traveling west bound and the power loss also was concerning. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

When slowing down to make a turn and then accelerating again the vehicle is not in correct gear to take off, it revs the engine but doesn’t move like it should. When this happens if you put shifter in manual mode and downshift it acts as it should. There is a TSB that fixes this problem but I think it needs to be a recall due to turning left in traffic and not being able to accelerate can cause wreck TSB-0032-26,.

The vehicle ofter hesitates for 1-2 seconds when accelerating from a stop or a slow roll. This has almost caused an accident on several occasions when trying to get out into traffic.

I own a 2025 Toyota Tundra 1794 with the 3. 4l twin-turbo engine. The engine failed at approximately 53,000 miles while I was driving on the freeway in houston, texas. I was traveling at highway speed when the engine suddenly lost power and the truck became unsafe to continue driving. I had to pull over to the shoulder of the freeway with traffic moving at high speed. My [xxx] daughter was in the vehicle with me at the time. The sudden loss of engine power at highway speed created a serious safety hazard because it left the vehicle disabled in active freeway traffic. The vehicle had been properly maintained with regular oil changes and normal driving conditions. After the failure the truck had to be towed to the Toyota dealership, which I had to pay for out of pocket. The dealership performed an engine teardown that took about one week. They informed me that the engine block and most internal components that come into contact with oil will need to be replaced. The dealership told me the failure is not currently related to the existing Toyota Tundra engine recall. The truck is currently at the dealership and they estimate approximately 30 days to complete the repair. The dealer also informed me they have multiple Toyota Tundra trucks waiting for engine repairs and that no truck loaner vehicles were available. My understanding is that a Toyota case number has been opened for this failure and that the diagnostic details are recorded in that report. I am concerned that sudden engine failures at highway speed represent a serious safety risk information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While at a 2-way stop sign, when attempting to accelerate while turning right, the truck hesitated and did not move. Pressing the accelerator further down did nothing for what felt like 1-3 seconds and then all of a sudden it rushed forward. This is incredibly dangerous as there were vehicles heading towards me. This is not the first time this has happened. It happens nearly daily, while the engine is warm, while the engine is cold, in eco, normal and sport modes. The only time I had zero issues was when the computer was reset after having service done to the truck. It ran incredibly well and shifted and ran as expected.

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 brakes squeal when reversing and sometimes when you’re driving forward coming to a stop. It has done this since the day I picked it up at the dealership. The dealership says there’s no remedy for it yet. The next thing is the front fog lights also draw moisture just like the rear reverse lights. Dealership says there’s no remedy for it or fix for it. I’ve had to have the radiator replaced twice in this vehicle and it only has 44,000 miles on it. The dealership says it’s a factory defect. Not sure if that’s true or not. It was not covered under warranty so I had to spend $200 to use my extended warranty. I do not think that is right it should’ve been covered under the manufacturers warning, especially if it was a manufacturer defect. The last but most important thing is the lag when you give it gas. This happens from a complete stop or also like if you’re trying to accelerate to get on the highway you can press it nice and slow and it won’t takeoff or you can mash on it all the way to the floor and it still takes a few seconds and then kind of vibrates and pops like it’s trying to skip gears before it takes off and goes. Dealership also says there’s nothing wrong with it. I believe it is a factory defect or some kind of wiring problem. The reason why I think it is a computer or wiring issue is that if you put the vehicle in sport mode, it will not do it coming from a complete stop. It does do it when you’re getting on the highway even in sport mode. I am on a few facebook forums and I see this problem where people report this problem all the time and ask how to fix it. I would like information on how to get Toyota to buy my vehicle back. These trucks have had so many issues with engine recalls, engine replacement, and other issues that are an actual safety concern and I do not feel like it is a safe vehicle to be traveling with my family.

I am an automotive engineer. I have been involved with vehicle development programs in the disabled vehicle conversion community for over two decades and have numerous patents in that space. I have been involved with vehicle testing and calibration as well. My vehicle demonstrates a significant hesitation when the accelerator is pressed that is not consistent. I live in a roundabout dense location where timing an entry into a roundabout is easy using a normal vehicle. The 1 to 2 second hesitation where there is throttle input and no action at all from the vehicle (engine does not rev, no motive power observed) is very dangerous. I took this up with Toyota and my vehicle was checked out and "learning transmission" memory was wiped clean with me being the only driver was the remedy. The issue got better for a short time but is back and this morning I pulled out thinking there was plenty of time in front of a bus a good distance away and the lack of motive power for a full second or two resulted in a near miss. This vehicle has about 20,000 miles and was purchased by me new. There are no warning lamps, and no dtcs thrown when this happens. I have seen several videos where people cite the same experience and a website where there is a class action lawsuit in place regarding this issue. This is completely separate from the engine recall issue. I feel as though this issue is a significant safety risk.

This was just the latest with this transmission. It happens 2 to 3 times per week. This time it was an intersection with a slight down hill. I stopped, then let off the brake as a car past in front of me. Since it was down hill, the truck started to roll forward. I then pressed on the gas pedal to pull out into traffic. The truck failed to responds for 1-2 seconds. There was plenty of space for a normal vehicle to make it, but with this delay, I barely made it. If you are not at a complete stop for at least 1 second, then accelerate, this thing fails to respond. It has been in many times for this, had the software updated, downgraded, generated reports for Toyota's engineering group. Still no fix. You never know how it is going to respond, but basically if you need it to accelerate, when you request it through the gas pedal, it will fail to do so.

The vehicle is either unresponsive or has a severe throttle delay from a stop or a very low speed, creating is a major safety issue. This could leave the vehicle in a position to not be able to accelerate, and risks becoming a hazard to other traffic, particularly at intersections. Understanding that a TSB is available for a transmission code reflash to resolve this issue, dealers are denying the repairs stating that they are unable to reproduce the issue in their limited test drives. It is not possible to predict when these severe hesitations occur, so reproducing the issue occurs on an unknown basis.

Throttle lag/ hesitation after complete stop.

My car got stuck in 4wd with 4l light blinking. I wasn't able to get out of the gear and the sensor had to be recalibrated just to fix this issue.

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