2025 Toyota Tundra

Have owned the 2025 Toyota Tundra for about 18 months. Multiple instances of delayed acceleration when stopped or almost stopped, sometimes as much as 3 or 4 seconds. Last time was in early June, 2026. This is very dangerous because when I pull out into an intersection it will start to go but then lose all power for a few seconds with traffic coming behind me. This is something Toyota needs to look into.

I have experienced a severe hesitation or delay in acceleration when accelerating from a stop or near-stop condition. While the issue has only occurred a few times over the past several months, on multiple occasions it happened while merging into traffic and nearly resulted in an accident. Toyota has issued Technical Service Bulletin (TSB-0032-26) addressing this condition. However, when I brought my vehicle to the dealership, Toyota documented that they were unable to reproduce or confirm the hesitation, and no repair was performed. This defect presents a significant safety risk. Unexpected loss of acceleration during traffic merges, intersections, or other situations requiring immediate power can place drivers and passengers in danger and could lead to serious injury or death. Given the safety implications and the fact that the remedy appears to be a software update requiring less than an hour to perform, I believe this issue warrants a formal safety recall rather than a voluntary Technical Service Bulletin. I urge NHTSA to investigate this matter and require Toyota to provide a recall remedy for all affected vehicles.

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

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.

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.

Vehicle: 2025 Toyota Tundra Component/System: Powertrain / Electronic Throttle Control / Transmission Response Complaint Description: I am reporting a serious safety defect involving delayed and inconsistent acceleration from a stop or low speed. What failed or malfunctioned: The vehicle exhibits a significant delay in throttle response. The electronic throttle and/or transmission fails to deliver engine power when the accelerator is pressed. The vehicle is available for inspection upon request. Safety risk: This failure creates a hazardous condition when entering intersections, turning across traffic, or merging. On multiple occasions, the truck failed to accelerate when commanded. In one incident, I pressed the accelerator approximately 75% and the vehicle did not respond for 2–3 seconds, nearly resulting in a collision. Reproduction/confirmation: The issue has occurred multiple times under normal driving conditions from a stop or slow roll. It is intermittent and unpredictable. Inspections: At this time, the issue has not yet been resolved and has not been successfully corrected. (Inspection pending / not yet corrected.) Warning indicators: No warning lights, messages, or fault indicators were present before or during the failure. The hesitation occurs without any dashboard alerts. Additional details: The delay is not typical turbo lag or minor hesitation — it is a complete loss of commanded acceleration for several seconds, followed by sudden engagement. This condition makes the vehicle unsafe to operate in traffic.

After dinner at a restaurant I went to pull out from the parking lot onto a road with a 40 mph speed limit. When I pressed the accelerator to turn, my truck felt like it was in a high gear and just barely moved forward. I let off the gas pedal and pressed again and the same thing. At this point I am drifting into on coming traffic without power. I hit the brake, moved to park, moved the setting to SPORT and then moved back into drive and only then was able to operated the vehicle properly and safely. Fortunately the person on the road did stop and did not hit me, but this is a VERY DANGEROUS situation and something is clearly not working properly.

When accelerating from a standstill, the car hesitates for 1 to 2 seconds after I press the accelerator pedal. This is a safety concern, especially when merging onto the highway (we have stoplight-controlled merge lanes where I live), where accelerating the vehicle is essential to a safe merge into traffic going 65+ mph. There have been no warning lamps.
