Other Fuel System Problems of Toyota Tundra - part 1

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.

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.

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.

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.

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.

Traveling on highwy bat 70 mph the fuel tank protection panel 77606/77641c came loose in the front after bracket support 77511 broke and the air pressure bent the protector down at the front and it hit the roadway and bounced up and banged against the tank area. I stopped, assessed damage, took picture and got off highway and drove home slowly. The subsequent part inspection showns fabrication errors in the part with fatigue failure and contaminated material. This could have been catastrofic failure with ontinued impact to fuel tank.

I'm having an issue my 2022 Toyota Tundra having incredible throttle lag issues involves a delay and sudden surge when accelerating from a stop, creating a safety concern, often described as a "dead pedal". It has caused me to get into numerous situations where I could've gotten hit by other vehicles. It is so dangerous! the dealership is unable to fix it and says to disconnect the battery regularly to try and "help" the issue.

Throttle hesitation when leaving from a stop. Completely random and occurs maybe a few times a month.

When accelerating from a stop it has a severe delay. I’ve read now this is not normal. Sometimes the delay can be 1-2 seconds causing confusions at like stop signs and such as I’ve pressed the gas and get nothing. Not reported to dealership but will on next oil change as this has been a persistent problem since purchase.

My Toyota Tundra is having issues with the fuel pump. It is saying I am using e85 fuel when that is not the case. As a result I am having issues with cold start. There are recalls however I am being told that my truck is listed among them despite having the same issue.

Truck regularly experiences throttle lag leading to dangerous/hesitating entry into traffic/intersections. Either each occurrence, after 1 to 4 seconds the vehicle will lurch forward hard after the pause. It has also happened when accelerating to pass on the highway. This also happened with the original and replaced engine.

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.

When starting from a very slight rolling stop I sometimes get no throttle response at all. When this happens I end up applying more throttle and I still do not move. Then after a second or two the truck takes off like a rocket. This usually happens at an intersection with the steering wheel turned one way or the other. Not sure if this is an engine or transmission issue or both.

Car stalls from stop during acceleration. There are times when there is no response from throttle.

The 2016 Toyota frame rust settlement (burns v. Toyota motor sales, u. S. A. , inc. ): this $3. 4 billion class action directly addresses premature corrosion in 2007–2008 Tundras (and similar models). It claims Toyota “knowingly failed to apply adequate rust protection,” leading to frame perforation despite later treatments like hof. The settlement’s “recurrent perforation” clause applies even after hof. My rusted-through fuel tank strap and holes in the rear cross member qualify. Hof ro# xxx. Claim #xxx my 2008 Tundra sr5 trd was treated with hof in Nov 2017. In November 2025 my mechanic told me the gas tank was falling out as the straps that hold the tank in place were completely rotted out. And rust perforation was on the rear cross member. He instructed me to get a safety inspection at a Toyota dealership to document the rust. Toyota of waldorf didn’t even schedule a appt, they told me to call the brand engagement center and that there was no possibility of repair because Toyota had no frames. Brand engagement refused to provide any guidance. I scheduled an inspection at koons Toyota of annapolis, which it failed inspection with multiple >10mm frame holes and a rusted-through tank strap (held by bungee). They deemed it unsafe to operate and unrepairable. They kept leaving out the information about the rust or the holes until they realized I was not leaving until they documented it properly. I have 3 versions. Despite zh7 expiration, this is a post-hof recurrence and safety hazard. I requested goodwill repurchase at 1. 5x kbb (~$12k) under the settlement’s intent. The brand engagement center had me call them and [xxx] ” announced she was my case manager, then almost as quickly announced it was going to “internal dept” for repurchase review, that she would no longer be my case manager, and that they would get back to me in 60 days. I said the average is 2-4 weeks, not months and that I expected a response in 3-7 days. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C.

Tundra has had and has throttle lag. Lag is so noticeable that other drivers notice. Following lag is a burst of power causing a jerk and or lunge forward. This is after a long pause. Happens on a roll, or start-stop situation. My truck has had the Toyota TSB applied a long time ago.

Throttle delay is extremely dangerous and has nearly caused numerous accidents.

Vehicle hesitates to accelerate from stop or slow roll when pedal is engaged. This hesitation nearly caused a collision when attempting a left-hand turn in heavy traffic. Problem can be reproduced easily and is exacerbated when on an incline. It has not been confirmed by dealer or service center. Occurs regardless of whether auto start/stop feature is enabled or not. Putting transmission in "s" mode and manually down shifting to first gear appears to prevent the issue. After the hesitation, when the vehicle begins to accelerate, it performs a "hard" acceleration, like the pedal was slammed to the floor, even though consistent pressure was maintained on the the pedal. Problem has existed since purchasing the vehicle new in Dec. 2023.

Ive been noticing a significant lag sometimes when I press the gas pedal. It last just a couple seconds. This could possibly become something bigger. Will update of it gets worse. Also the cruise control doesn't hold the set speed it stays 1 or 2 miles under.

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.

While starting to accelerate from a stop whether it is going straight or turning the truck hesitates and takes multiple seconds to start accelerating leading to a potentially dangerous situation especially when turning and you can't get out of oncoming traffics way. Also when at a slow roll trying to accelerate the truck just does not apply any power for multiple seconds delaying movement and potential to avoid an accident.
