2025 Toyota Tundra

On July 20, the vehicle experienced a catastrophic mechanical failure resulting in a total engine seizure while operating. The failure caused an immediate, sudden loss of motive power, forcing the vehicle to become completely immobilized on the Interstate highway. This unexpected loss of propulsion created an immediate and severe highway crash hazard for myself and surrounding traffic. The vehicle was towed to an authorized Toyota dealership on July 20 under the 5-year/60,000-mile factory powertrain warranty. The vehicle has remained completely out of service since that date. The dealership has tentatively scheduled the engine repair and replacement to begin on August 24 or 25, meaning the vehicle will have been non-operational and out of service for over 35 consecutive days before repairs even commence.

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.

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

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

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.

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.

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.

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.
