2025 Toyota Tundra Powertrain & Transmission Problems

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.

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 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.

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.

I own a 2025 Toyota Tundra 1794 with the 3.4L twin-turbo engine. The engine failed at approximately 53,000 miles while I was driving on the freeway in Houston, Texas. I was traveling at highway speed when the engine suddenly lost power and the truck became unsafe to continue driving. I had to pull over to the shoulder of the freeway with traffic moving at high speed. My [XXX] daughter was in the vehicle with me at the time. The sudden loss of engine power at highway speed created a serious safety hazard because it left the vehicle disabled in active freeway traffic. The vehicle had been properly maintained with regular oil changes and normal driving conditions. After the failure the truck had to be towed to the Toyota dealership, which I had to pay for out of pocket. The dealership performed an engine teardown that took about one week. They informed me that the engine block and most internal components that come into contact with oil will need to be replaced. The dealership told me the failure is not currently related to the existing Toyota Tundra engine recall. The truck is currently at the dealership and they estimate approximately 30 days to complete the repair. The dealer also informed me they have multiple Toyota Tundra trucks waiting for engine repairs and that no truck loaner vehicles were available. My understanding is that a Toyota case number has been opened for this failure and that the diagnostic details are recorded in that report. I am concerned that sudden engine failures at highway speed represent a serious safety risk INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The gas pedal has no response when coming to a stop and pushing on the gas pedal. Multiple times I come to a stop, push the gas, no response, 1-3 seconds later; the vehicle jerks forward. On occasion it has nearly lead to an accident and I do not feel safe in my vehicle.

When pulling out on the highway I have lag in the powertrain

Throttle lag When I accelerate from a stop, such as at a red light or stop sign, after I gently press down on the gas pedal, there is consistently a 1-2 second delay before the truck accelerates. This can cause potential delays in getting through an intersection, in turning in front of oncoming traffic, and getting going in traffic. This happens consistently since I’ve owned the vehicle since the summer of 2025.

The vehicle has a recurring safety-related defect where there is a long, unpredictable pause (1–3 seconds) between pressing the accelerator from a stop and the truck actually accelerating. This hesitation occurs when pulling away from a stop sign, traffic light, or after braking to a stop in traffic, and is not normal throttle response or turbo lag. During this delay, the engine revs slightly but the truck does not move, creating a dangerous situation where the vehicle fails to respond when expected, especially in intersections or when merging. After the pause, the truck often surges forward abruptly, which can cause jerking and loss of control.

This is a known issue on previous year vehicles. Gas pedal response is delayed excessively causing scenarios where one could become injured if attempting to pull out from a full stop or rolling stop expecting the vehicle to move and it doesn’t. Reference Toyota TSB-0111-22 for vehicle hesitation while accelerating. Brought my vehicle into a Toyota dealer in Scranton PA on 12/16/2025 with this info and they were unable to duplicate the issue along with stating that TSB does not apply to this year vehicle. Look online there are tons of forums stating this issue is still present in the newer year models like mine which is a 2025. This is a serious problem as it’s happened at random with no clear reasoning other than potential programming issue between the transmission and gas pedal coding.

Throttle hesitation from stop. Delay in acceleration poses a safety risk when driving.

Several times when accelerating around traffic or cutting across the highway to work I have been nearly t boned when I'll step on the gas and the truck hesitates or does nothing. It usually hesitates for 3 to 5 seconds and then starts spinning tires or other times it will just start lightly accelerating no matter how much gas I give it. It's dangerous because the vehicle is so unpredictable and will eventually result in an accident.

I’ve noticed that my Toyota Tundra occasionally fails to start moving from a complete stop at a light or stop sign and hesitates. I’ve pressed the gas pedal all the way down, but it doesn’t respond. It usually takes a second attempt before it will move from a stopped position. This first happened during my first week of owning the truck and has occurred a few more times since. I didn’t think much of it at first, but it happened again while I was stopped on an incline in a right-turn yield lane. I released the brake, and when I pressed the gas pedal, nothing happened—the truck even felt like it was rolling backward. I floored the gas, and after a few seconds, it finally took off. I started looking online and found that many others have reported the same issue. There’s even a YouTube video from someone who experienced it: [XXX] I plan to take the truck to the dealership to have it checked out, but this definitely feels like a significant safety concern. I’ve made no modifications to the truck; it’s completely stock with no tuners or aftermarket adjustments. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When trying to pull out into traffic from a stop there is a hesitation at times. I go to press on the accelerator and the truck does not always move. There seems to be a delay at times. Seem dangerous when pulling out into traffic. It has happened multiple times. No sure if it is the transmission or what.

Vehicle stalls after stopping often

Throttle delay/ hesitation that is very unpredictable.

Unintended acceleration. When you stop the truck, and have the brake on, the rpms go down to idle ~650. As soon as you lift the brake, without touching the accelerator, the vehicle starts ramping up the rpms and moving. On level ground it will go to 1000 easily before you have to stop it. It will pull up a grade even while towing my boat. If you're in a line a traffic, say at a traffic light, and the light changes, traffic moves and the car ahead takes off their brakes, and you do same, the truck starts moving faster than the vehicle ahead without touching anything. It's idling too fast without the brake and doesn't stay at idle once the brake is off before you push the accelerator. First the dealer told me everything was "Normal" - it's supposed to do that. I've been driving vehicles since 1962, so I think I know what I'm talking about. They told me to call Toyota. Toyota started a case. They took it in for an factory inspection because I think this might be related to a non highway collision with a bldg, I had shortly after I got it, I'm not sure. I put into park in a parking space but apparently it didn't engage, only into reverse. I was looking for something and the truck started backing up and hit the gas station bldg close behind. The anti-collision was off, because you have to turn it off to tow. And I hadn't turned it back on yet. This truck has way too many audible alarms and very annoying, especially when backing or exit the vehicle. I don't need to know that I'm out of the vehicle.

There is an interment issue where the vehicle fails to accelerate from a stop when accelerator is applied. This issue is present in my current vehicle and my previous 2023 tundra. I have brought up concerns to the dealer and manufacturer and am told every time that the concern cannot be duplicated, but I feel that it is going to lead to a crash not only for me but other owners

Making a right turn from a stop. I pressed the accelerator and the vehicle barely moved. Cars were coming in my direction and I had to move. I let off the accelerator quickly pressed the accelerator again. The vehicle did start moving at normal rate. This first attempt was very concerning and almost caused me to get in an accident.

I’ve notice that when coming to a stop or yield when you press the gas pedal to go or continue driving there’s a lag or delay. This has happened more than 4-5 times since I purchased the truck on December 23, 2024. The last time it happened was last Saturday August 9, 2025. Truck was on sport mode, Auto Stop/Start was off. I’m at a light waiting to make a right turn, when I pressed the gas pedal to go it went forward and felt like I slammed the brakes. I had to take my foot off the gas pedal, brake, then gas it up again to go. It is a little scary because this could cause an accident. I’ve taken my truck to the dealership about this, but they said they can’t do anything about it because they cannot recreate the issue.
