2024 Toyota Tundra

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.

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
