The TCM is faulty. There is a tsb so Toyota is well aware of the issue. They will not take care of it under the power train warranty. The TCM doesn't shift the vehicle correctly. This lag and funny shifting almost caused an accident.
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.
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.
The contact owns a 2024 Toyota Tundra. The contact received notification letters for NHTSA Campaign Numbers: 25V322000 (Exterior Lighting) and 25V767000 (Engine and Engine Cooling); however, the parts required to complete the recall repairs were not yet available. Additionally, the contact stated that while reversing, an abnormal popping sound emanated from the differential. No warning lights were illuminated. A local dealer was contacted, but the vehicle was not diagnosed or repaired; however, the dealer sent an email offering a vehicle buyback. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 4,300.
While driving my 2024 Toyota Tundra Hybrid, the engine suffered a catastrophic seizure at approximately 37,974 miles. The dealership retrieved substantial metal machining debris (swarf) from inside the engine, which had contaminated the #1 main bearing. This is the exact same manufacturing defect Toyota has publicly acknowledged in multiple safety recalls for 2024 Tundras. Service Manager Dan Moran at Toyota of Colorado Springs confirmed during a recorded call that his dealership has seen the identical debris-related engine failure in other hybrid Tundras. Despite this, Toyota excludes all hybrids from the recalls. Even with clear physical evidence matching the recalled defect, Toyota directed an in-house rebuild (using a new short block but many of my original contaminated components) instead of providing a full factory crate engine. I was never offered a choice in the remedy. This sudden engine failure created a serious safety hazard due to unexpected loss of power. The current repair does not fully eliminate the known root cause (manufacturing debris contamination). The vehicle was well within warranty at failure and remains so. The dealership has the debris and full repair records available for inspection. I have also submitted the debris photo, repair documents, and recorded call summaries to NCDS (Case #[XXX]) and the Colorado Attorney General’s office.

The contact owns a 2024 Toyota Tundra. The contact stated that on two occasions while driving at undisclosed speeds, the vehicle lost motive power while attempting to accelerate from a complete stop. Upon depressing the accelerator pedal, the vehicle abruptly stopped in the middle of an intersection, with the brake warning light illuminated. The vehicle resumed normal operation after several seconds. The vehicle has not yet been diagnosed or repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 12,000.
Engine has experienced surging and makes strange noises
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.
Vehicle: 2024 Toyota Tundra Double Cab | VIN: [XXX] | Mileage: ~19,200 No crash or injury has occurred. This report concerns an unresolved safety defect. My Tundra intermittently fails to accelerate when the gas pedal is pressed from a slow roll (3-18 mph). The engine revs but the vehicle does not move for 1-2+ seconds before the driveline abruptly engages. This occurs at intersections and during low-speed traffic transitions. It is worse on cold starts. I have experienced sudden unintended deceleration while attempting to enter traffic. This vehicle is covered under Safety Recall 25TA14 / NHTSA 26V320 ("Engine May Stall During Driving"). The TSB remedy was applied at my dealer on June 11, 2026. The remedy did not resolve the condition. I have OBD-II logs proving the defect persists post-remedy. Using Torque Pro at 10 Hz, I captured 55 instrumented hesitation events on June 11 alone -- 18 on the drive to the dealer before the TSB, and 37 after leaving. The worst single measurement shows a 1.7-second delay between pedal input and throttle blade response. My full dataset spans 131 events across multiple drives. Highway driving is completely normal throughout; the defect is exclusively a low-speed tip-in condition. The dealer has been unable to duplicate the condition across five repair order presentations since February 2025. The vehicle spent 105 days in dealer possession with no repair performed. I am reporting this as a failure of the Recall 25TA14 remedy on this specific VIN. Full OBD-II logs, GPS data, timestamped event charts, and all service records are available on request.

Loss of power limp mode at highway speeds, error notification on screen to visit dealer. Almost caused sever wreck. Hybrid motor did nothing to mitigate risk.
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.
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.
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.
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.

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.
It has been occurring ever since I purchased the truck in October 2023. I finally thought I should say something. Usually, the truck is at a complete stop. The truck can be warm or cold. As I press the accelerator down to move in the forward direction, there is a hesitation. No immediate acceleration. It lasts for at least one second before the acceleration begins. This can create a serious safety issue when there is cross traffic. Putting myself and passengers in possible danger of a collision. This occurs almost every time I drive the vehicle. When I had my truck in for a recall on 4/19/26, I asked a Toyota service manager if this is a common problem. He told me it is very common in the 2024 Toyota Tundra, with a V6 twin turbo. This leads me to believe that the Toyota Corporation is aware of the problem. As per the service manager, Toyota has not done anything about this issue and there isn’t a repair for it.
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.
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.

The contact owns a 2024 Toyota Tundra. The contact stated that the vehicle had consistently experienced a throttle lag while driving from a complete stop and while decelerating. Additionally, the contact stated that while accelerating from a complete stop at an intersection, the vehicle hesitated to respond and then lurched forward while responding. There was no warning light illuminated. The failure had been recurring intermittently. The vehicle was taken to the dealer, where an unknown repair was performed; however, the failure persisted. The dealer was notified of the failure. The contact stated that the dealer had advised that data from the Event Data Recorder(EDR) had been erased while in the process of correcting the throttle lag. The vehicle was not repaired. Additionally, the contact learned that a Class Action Lawsuit was filed in the State of Vermont due to the failure. The manufacturer was notified of the failure. The failure mileage was approximately 100.
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.
Throttle lag, takes a couple of seconds for the truck to register me pressing on the gas before jolting forward. Not only frustrating but dangerous.
Numerous times (4-5) the truck has failed to accelerate from a rolling stop and/or a full stop. One time recently, I stopped and quickly tried to turn left onto another road. As I accelerated, the engine lagged and the truck felt as if it would stall. In all instances, the transmission seems as if it has not downshifted into 1st gear... and appears as if it is stuck in 3rd or 4th gear and the engine struggles to keep up. No warning lights or messages appeared in any of the instances. I am taking it to the dealer for them to look at.
I was stopped and went to pull out of the gas station. With my foot on the throttle I pull out. And it would not accelerate. I had to pump the gas pedal I almost got hit by oncoming traffic due to the lack of acceleration this has happened multiple times Very dangerous
Extreme lag response from stop on numerous occasions causing vehicle to not move for well over 1-2 seconds. Seems to happen mostly within 5 mins of start up. Had to stop slightly out in intersections several times due to this lag not allowing me to proceed safely. It doesn’t sputter at all, it just doesn’t move
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
