2025 Toyota Tundra fuel/propulsion system problems

“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.”

“Problem - throttle lag/hesitation/lurch. Truck won't go when throttle is pressed for a couple seconds cold or hot. Mentioned the problem on my 5000 mile service. Service tech said he could not reproduce the problem but happens with my drives 95% of the time. No warning lights have appeared.”

“When coming to a rolling or quick stop and then attempting to maneuver across traffic, my truck hesitates for about a full second before accelerating. This delay can create a dangerous situation for myself, other drivers, and pedestrians. I believe this is a safety issue that Toyota needs to address promptly.”

“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…”
