Other Fuel System Problems of Toyota Tundra - part 1

Since taking delivery of this brand new 2026 Toyota Tundra hybrid, I have experienced a persistent shuddering at low speeds, approximately 15 to 25 mph. The shuddering is most pronounced during slow, gradual brake application — the more gently the brake pedal is pressed, the more severe the shudder. It is also present to a lesser degree during acceleration. The issue appears to involve the transition between the regenerative braking system and the conventional friction brakes in the I-force max hybrid system. The vehicle was taken to an authorized Toyota dealership for a first repair attempt. Tires were rebalanced and inflated to 40 psi, exceeding the manufacturer's recommended specification. The repair order was closed with the notation "test drove and vibration is gone. " this conclusion is inaccurate. The shuddering was only partially reduced — the root cause was not identified or resolved. The safety concern is significant. I have found myself instinctively adjusting how I apply the brake pedal to avoid triggering the sensation. A vehicle that changes the way its driver brakes is dangerous. A second repair attempt is being scheduled at the selling dealership.

Unknown truck stuck in branchport NY started truck. Drove for ~20miles then died has ~1/4 tank of gas started truck again let it idle then died again started truck again, gave it gas, ran fine, then died started truck again, reversed it to turn around and died again in middle of intersection.

Ive been waiting for years for the previous recalls I have been informed about to get fixed. Feul system,brake lights. Was told by Toyota that someone would call me to come to get them taken care of. In the meantime, constantly checking that my brake lights are working before departing on any excursions in truck & patiently waiting for Toyota to reach out when they were gonna fix the first 2 recalls that I was notified about. I can't recall the date exactly, but I was driving on the highway w/ my still backward carseat, facing 2y. O. Baby safely strapped in,thankgod. As accelerating into my lane, heard huge boom like an ied. Immediately, the check engine light among others came on. Truck immediately lost power & was violently shaking. Felt it in the steering wheel, but largely in engine compartment. @this time,I tried to get over to shoulder to a safe place. I turned the car off. Let it rest checked on my infant in back made sure he was ok. After letting car rest, turn back on to my surprise all lights were off. I was w/in few miles of home so went directly back, never getting to my intended destination. Shortly before driveway, all lights came back on & multiple service messages. Since then the truck has not been driveable,as we have specifically looked up recalls,thusly Nov. Recall matched lights on the dash for the specific make,year, model of truck. From my understanding, it says that there is no remedy for such recall. But that is untrue. The remedy is an entirely new engine. They just haven't rolled out the recall info to everyone applicable. I am unable to work. My home is without a vehicle and this is unacceptable. Along w/ safety risk to me and infant. I'm sure Toyota doesn't want to admit or remedy because that is very costly. But this was a mistake made by the company. And it should be remedied, because our family is suffering in various ways. Lost revenue. Inability to respond if emergency etc. I need a new engine. & in the interim,I need a car supplied while fixed.

This is a reoccuring issue and happens daily. When the vehicle is cold and sitting all day or all night, on the first 5 minutes of driving or so, when you push the accelerator pedal from a dead stop or rolling stop, there is no throttle/engine response for at least 1. 5-2 seconds. This is a highly unsafe condition and can lead to a traffic collision. I have reached out to Toyota corporate about this and they said to bring it into my local dealer, dick hannah Toyota in kelso, wa to perform the rolling stop TSB that is out on these Tundra trucks. I received information from dick hannah that when they went to perform the procedures to take care of this TSB, that it had already been done and that there was nothing they could do further. They asked me to document the conditions to try and get Toyota corporate to do something about it. I asked if there wasn't a recalibration they could do or anything else to make this condition improve, and they said no there is not. I expressed my concerns saying that there is nothing to document, that this happens everyday and is a daily occurence whenever the vehicle has been sitting for a long period of time. I have reached out to other vehicle owners on vehicle forums on the internet that are experiencing the same exact problems with no remediation from Toyota dealers or Toyota corporate. I was even offered to get into a split to hire a lawyer to get this unsafe condition remedied. This is a big deal and should not be overlooked and written off by anybody.

Driving on the interstate and the truck surged very hard. The truck began to surge very hard and went into decreased speed mode. We were told by the dealer there is a TSB for the pcm. This decreased power caused the truck to not be able to travel over 25 mph in a 70 mph zone. This caused an unsafe situation.

2016 flex fuel Toyota Tundra with 118,00 miles was towed to Toyota dealer in las cruces with a no fuel issue. After the analysis it was determined the fuel pump over heated burning out conector and wiring ,but the pump was still working. According to Toyota TSB 0166-19 this is a problem the can arise if the alcohol fuel density id is not updated. I told the dealer to due repairs on vehicle even though a fuel pump was installed and reflashed at 114,000 miles. Viva Toyota of las cruses advicate stated that a reflash is all the vehiles needs and does not desire to change the alchol fuel density to updated id as per TSB-0166-19, so I am worried I will be operating a vehicle with a fuel pump that will over heat and burn out connectors again. I called Toyota complaints and they told me they cannot make a dealer do any repairs.

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.

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.

The fuel pump component or system failed or malfunctioned the engine tried cranking but would not start. The problem has been reproduced to an independent service center, where I was notified of a safety recall on Toyota Tundra. No other inspections have been performed. There are no warning lamps messages visible on the vehicle in question. The vehicle will not start until repeated starts are performed. Vehicle idles roughly before regaining normal idle. One other past similar incident of this type has occurred. No other.

After I put gas into the vehicle gas tank, the gas tank gauge indicated the tank was 75% full. The following day when I started the vehicle the gauge indicated the tank was 100% full and I did not add a drop of gas into the tank. Days later the tank appears to be stuck on 100% full. My fear is that I will not realize when the tank approaches empty at a very inopportune time.

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.

Throttle response is unpredictable. From a stop sign, acceleration is difficult to predict. Sometimes a one second delay occures before acceleration power is effected. With the time delay the throttle has been pressed further than normal. In heavy traffic, a collision could be possible. The problem got worse after a firmware update, during a safety recall to replace rearview touch screen. Pedal lag problem is noted on Toyota Tundra forum.

On 2022 - 2024 Toyota Tundra models, the vehicles are experiencing an issue where the fuel sensor will reset the digital and analog fuel displays back to showing a full tank without adding fuel to the tank. On my vehicle, the reset has been occurring around the 380 mile distance to empty level. I see numerous other reports about individuals experiencing the same issue. I believe this is a defect and could cause a vehicle to run out of gas without the driver expecting it.

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.

The vehicle experiences hesitation when starting to move from a stop. So if I come to a stop and pull out into traffic it sometimes hesitates before applying the throttle that has been input via the pedal. This could cause serious injury because its almost impossible to determine when its safe to pull out into traffic because you do not know how long it will take for throttle to kick in.

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 brakes squeal when reversing and sometimes when you’re driving forward coming to a stop. It has done this since the day I picked it up at the dealership. The dealership says there’s no remedy for it yet. The next thing is the front fog lights also draw moisture just like the rear reverse lights. Dealership says there’s no remedy for it or fix for it. I’ve had to have the radiator replaced twice in this vehicle and it only has 44,000 miles on it. The dealership says it’s a factory defect. Not sure if that’s true or not. It was not covered under warranty so I had to spend $200 to use my extended warranty. I do not think that is right it should’ve been covered under the manufacturers warning, especially if it was a manufacturer defect. The last but most important thing is the lag when you give it gas. This happens from a complete stop or also like if you’re trying to accelerate to get on the highway you can press it nice and slow and it won’t takeoff or you can mash on it all the way to the floor and it still takes a few seconds and then kind of vibrates and pops like it’s trying to skip gears before it takes off and goes. Dealership also says there’s nothing wrong with it. I believe it is a factory defect or some kind of wiring problem. The reason why I think it is a computer or wiring issue is that if you put the vehicle in sport mode, it will not do it coming from a complete stop. It does do it when you’re getting on the highway even in sport mode. I am on a few facebook forums and I see this problem where people report this problem all the time and ask how to fix it. I would like information on how to get Toyota to buy my vehicle back. These trucks have had so many issues with engine recalls, engine replacement, and other issues that are an actual safety concern and I do not feel like it is a safe vehicle to be traveling with my family.

The engine repair was a short block only, even thoe the main bearings spun and sent debis threw the engine. #1 rod went as well. Apon recieving the truck back, with in 200 miles, I've had the same hesitation with the engines as I had just before the first engine failed. Took it by the dealer and no issues found. Oil preasure stays up and temp normal. I've had many issue with throtle lag sence day one. The milage has stayed in the low 11 gpm when before I would get on average 14 to 16. Dealer stated Toyota would make it right if the engine fails again. Very unhappy with Toyota as I feel they are just kicking the can down the road.

The engine in my 2026 Toyota Tundra has significant throttle delay/lag when its cold - even if I let it warm up - it still has significant delay in throttle response - the truck has poor light throttle response and then lurches (even with the most minute progressive throttle input). This almost caused an accident where I nearly got t-boned because the vehicle crept a bit and then suddenly lurched quickly. The vehicle was also hesitant to reach 60mph (even though it was warmed up) after about 10 minutes of driving the vehicle started operating normally. I have a concern for safety everytime I drive this vehicle.

Sometimes the engine will randomly turn off while driving and become hard to restart like it’s not getting fuel.

When starting up my truck in the morning there is rough idle that cause truck to sputter and sound horrible. It eventually smooths out but I believe the computer needs flashing. When I look online some have a recall for the engine 3ur-fbe / 2018 Toyota Tundra, but when I put in my VIN # it shows no recall and throws off check engine light code. Also my radar sensor that it on for cruise control is showing up on dash please contact dealer and flashing. They have replaced this before with recall and now it’s acting up again. Also traction control is lighting up I. The dash as well blinking along with all these codes.

Add a stoplight or stop sign at a full and complete stop…. I pressed down the accelerator and nothing happens for about a second and a half… when it finally does respond, it jumps as if it was struggling to get into gear and popped itself… however, then it goes right back to normal. . But the slow starting happens very often. Definite lag when punching on the gas.

Were were driving, my 2021 Toyota Tundra, just stopped running. No check engine lights had come on until the engine stalled as we coasted to a stop on the side of the road. We had it towed to the central maine motor in waterville, maine 04901. Central maine motor -Toyota service just got my truck in to a service bay today 1/29/26 and in formed me the failure was due to the fuel pressure module and a fuel pump failure. Toyota has other years of vehicles that they have issues recalls for and my truck has the same fuel system and fuel pump as in those year vehicles, but no recalls for my truck, a 2021 Toyota Tundra built in sept/oct of 2020.

There have been multiple times, since owning the vehicle, when there is dangerous throttle lag. I step on the gas to turn and nothing happens for a few seconds. It can be pretty scary when there is a car coming and the truck just rolls for a few minutes before accelerating. It’s become a major safety concern for my family.

I have had multiple occasions where I have pushed on the gas pedal to accelerate from a stop and the truck does not go. This has almost caused accidents when attempting to pull out into traffic. This happens almost on a daily basis. The lag/pause can be very short (0. 5 seconds) or very long (2-3 seconds) in my experience.

I get random lags in thorttle engagement when starting from complete or rolling stops. When this happens, it behaves like there is a delay between the throttle input and the engine resoponse. Push the throttle to go, and no go, and after a delay of usually part of a second, then it jerks and goes. Most times there is no problem and the throttle responds correctly, but this issue occurs randomly almost every time I drive.

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.

Unacceptable fuel economy. Epa stats 18/23, I have no been able to manage over 14. 6 mpg. Truck has 16,xxx miles on it. I am seeing online this is very common. Something needs to be done about to blatant over fabricated numbers.

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.

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.

The vehicle was having issues with the fuel pump which was a known safety recall for the 2018 Toyota Tundra vehicles. The service man said that when he pulled up the safety recall for our VIN number that it didn't show anything, but we needed a new fuel pump according to the service codes that were coming up after inspection. They made us pay for the fuel pump before we left the dealership. The vehicle was too dangerous to drive without having the work performed (getting stalled out or stuck on the highway) so we had to pay for the work. Toyota said that I could file a complaint with NHTSA to get my vehicle added to this recall and then try again for reimbursement. I have the repair paperwork if needed to support this claim.

This is ridiculous if there’s debris in the engine of a risk for it and risk for the engine to go I want a new vehicle there’s 18k miles on this truck brand new shape and I will be putting my family in this. This is a risk I’m not willing to take. This needs to be bought back.

When rolling in to a round about (rotary) at a slow speed and the applying throttle the truck takes a second or tow before increase forward motion. The lag time is usually around 1. 5 seconds and when the time has lapsed it lurches forward. This hesitation in forward motion has put me and my passengers in danger of being t-boned multiple times. The modes most often used and notice this delay is eco, normal, and comfort. It's been this way since day one and when mentioned to the dealer I then get a response that it is normal.

The truck, randomly experiences hesitation, and or lag when pulling out from a dead stop. Twice it has been so bad as to nearly cause an accident. It also causes out of control acceleration as you don't know when if if the truck will actually accelerate or how much.

There is a well-known issue with these new model Toyota Tundras where there are problems with acceleration. When at a stop and pulling out from the stop, the engine and acceleration hesitate, and there is a flag of between 2 to 5 seconds before the vehicle starts moving. The gas pedal is depressed and there is a hesitation or lag of several seconds before forward movement progresses. There was a Toyota safety bulletin update that was supposed to fix the problem and it did not. Many users are still reporting the same problem and it’s just as bad as it was before. This creates a massive safety issue when pulling into traffic or trying to increase speed to keep up with the flow of traffic when initially pulling out. My truck specifically is experiencing this anywhere from one to three times a week.
