Other Fuel System Problems of Toyota Tundra - part 1

The fuel guage on the dashboard shows inccurate infroamtion. I filled up the tank and went out of city. Once I came back home, next morning it was showing full tank. I was unsure about the quantity left, I filled up the tank and it was almost 11gallon missing but it was showing full even on the gas station. It was fixed after a while but again today, it shows the full tank on dashboard but I saw half last night. I seached up online and it shows so many other people having the same issue. They also put some solutions but none of them worked for 2023 Tundra. This could be a great risk if you are on a long route and do not know how much fuel left .

I had an independent service center diagnose the issue with my 2018 Toyota Tundra. My truck would not start so there was no safety concern, but if the fuel pump failed while driving then the safety concern rises. The electrical connection inside the fuel pump was melted. There was no warning signs of the issue, it just would not turn all the way over. I looked up that the 2018 Toyota Tundra w certain VIN #'s have a recall for the fuel pump, unfortunately my VIN # is not included.

On Wednesday 10/21 at approximately 11:30pm I was traveling on the clearview expressway. While changing from the middle last to the left lane at 20mph due to a construction merge with some traffic. When trying to accelerate the truck lost all throttle power and my speed quickly dropped to 12mph before throttle response came back. No noticeable or harsh change of gear for this episode.

On Tuesday 10/21 at approximately 4:30pm I was on the grand central parkway traveling about 50mph. When trying to accelerate the truck lost all throttle power and I quickly lost speed down to 40mph before throttle response came back. There was a noticeable change in gear upon throttle resuming.

On Saturday 10/18 I was traveling about 60mph on the long island expressway at approximately 12:30pm when I went to accelerate to pass a vehicle. Immediately upon pressing the accelerator the truck lost all throttle power and I quickly lost speed down to 45mph before throttle response came back. The truck harshly went into gear once throttle power resumed.

Cold starting problems so the dealer diagnosed as a defective fuel pump.

The engine of my 2023 Toyota Tundra failed at approximately 34,500 miles. The failure involved sudden loss of oil pressure and severe internal damage, with metal shavings found in the oil and oil filter. The oil filter itself detached during the incident and was later recovered with metallic debris inside. The vehicle and the recovered filter are available for inspection upon request. While accelerating from a stop light on a busy morning public road, the engine suddenly lost power, illuminated multiple warning lamps, and entered limp mode with “low oil pressure” and “engine malfunction” messages. The truck rapidly leaked oil, creating a roadway hazard and putting me, my wife & son, and other drivers at risk of accident. I was able to limp the vehicle home . 5 miles from the incident at reduced speed, but complete engine seizure was a possibility. Toyota of fort walton beach inspected the vehicle, confirmed metal shavings in the oil pan, documented codes p05202 and p052049 (low oil pressure and oil pressure sensor stuck in range), and noted “oil was very metallic. ” the vehicle was inspected by Toyota dealership technicians and corporate representatives. I also have possession of the oil filter and photos/videos from the inspection. At the moment of failure, the dash displayed low oil pressure, check engine light, and a message regarding engine/electronic malfunction. Prior to this event, there were no warning signs — the truck had been serviced two weeks earlier at 33,360 miles, and I drove approximately 1,200 miles without incident until the catastrophic failure. This failure matches the description in Toyota recall 24v-381. My vehicle’s build date (February 27, 2023) is less than two weeks outside the published recall production window, yet the symptoms and inspection results are identical. I respectfully request NHTSA investigate whether additional 2023 Toyota Tundra vehicles outside the current recall window are affected, as my case demonstrates the same hazards.

You start with a half tank of gas or so. Then you park on an incline like a driveway. When starting the truck again the fuel tank shows full tank and more miles available till empty which is inaccurate. The gauge does not reset till you refill. Workarounds online do not work. This is a safety issue in mountain driving when you park you may miss how much gas you have left and can stall causing an accident or being stranded in a remote area. Toyota says they are aware but online reports show it has been a known issue since 2022. I feel this should be addressed before someone is hurt or stranded. This issue has occurred multiple times to me.

Fuel gauge won’t reset after filling the tank or it will stay on full after using the entire tank of gas. Running out of fuel on the freeway is a major safety issue!.

Bought the truck from bill luke marana was told there were no major safety issues with recalls and that the only recall was debris in engine that didn't have a fix yet. . . . Drove the car from dealership to home, upon arriving home my wife smelled gas, I thought it was cleaning fluid smell or something. Drove the truck to circle k smelled gas but though it was circle k . Drove the truck once more to pick up an employee so I could drop him off to drive home the car I left at the dealer . During this drive the smell of gas became undeniable . Upon arrival home the truck was parked my employee ( who had been driving behind in a different car) jumped out and said the truck was spraying gas . My daughter exited the passenger side of the vehicle and was misted with gasoline. We subsequently found a fuel line was shooting out gasoline. I called bill luke and told them to tow the truck back they said they couldn't so I was put in a position of having to drive the car back to the dealership. I was in fear of my life if driving this car so I was forced to pay a tow truck to return the truck to bill luke. After speaking with bill luke management I was told there are 2 major recalls with the vehicle first debris in the engine that can cause engine failure while driving and second a problem where the fuel line rubs against the brake drum or pad and can chafe to the point of leaking. The second recall issue is the one that put us in danger. I understand that recalls happen but I am under the impression that dealerships have a paramount responsibility to make sure the cars they sell are safe and have complied with major safety recalls. I don't believe this was done at bill luke marana . I believe bill luke marana put me and everyone on the road in danger to sell a car. Please address this monumental failure will all bill luke sales offices and service centers to prevent unnecessary death or suffering in the future.

I am writing to formally document a series of serious safety incidents and ongoing concerns regarding my 2024 Toyota Tundra, which I believe reflect a critical design flaw and a failure by Toyota to act in accordance with its obligations to customer safety and product reliability. In August 2025, while driving on the interstate with my minor child in the vehicle, I experienced a sudden and unexpected engine malfunction. The failure required me to swerve off the road at high speed, nearly resulting in a serious collision. This incident placed both my life and my child's life in immediate danger. The vehicle was towed via Toyota’s sos service to green’s Toyota of lexington, ky. Upon evaluation, I was informed by service manager justin that the issue was consistent with the engine failures that led to a recall of the 2022 and 2023 Toyota Tundra models. However, because my 2024 model has not yet been included in the recall—despite sharing the same apparent defect—I was told that Toyota would rebuild the engine rather than replace it. I expressed strong concerns regarding the safety and long-term reliability of a rebuilt engine in a new vehicle. I was reassured that a rebuilt engine would be “just as good,” despite clear evidence to the contrary based on subsequent events. As a result of this dangerous failure and Toyota’s inadequate response, I submitted a formal buyback request to Toyota customer care, citing serious and ongoing safety concerns. The dealership nevertheless indicated I would likely be denied a buyback, which I found deeply troubling given the known defect and the high-risk circumstances involved. During the initial repair, I visited the dealership to retrieve personal belongings and observed the vehicle in a completely dismantled state. The cab had been removed, and the engine was fully disassembled with parts scattered on the ground. This unprofessional and chaotic environment caused further loss of confidence in the repair quality and safety of th.

Vehicle occasionally stalls on acceleration and deceleration. Occasional stall on idle. Check engine light does not illuminate. After several stalls; warning lights for trainer brake controller, forward anti-collision, and cruise control errors illuminate. Diagnosed as bad fuel pump and fuel pump modulator. Fuel pump and modulator replaced and issues rectified.

My fuel pump died with symptoms consistent with other 2018-2020 Tundras involved in a fuel pump recall.

Engine is misfiring, truck vibrates when breaking when accelerating the engine cuts out dealership confirmed at service on 2/4/2025 that sensor needs to be replaced, need breaks, four tire rotation no no.

Gas mileage at best 12mgp on full tank, despite highway driving and does not matter what mode the truck is in . . . Dealership refusing to look at potential issue . . . Wide reports on forum on very low gas mileage.

I recently put my boat in the water with my 2022 Toyota Tundra at local boat launch. When I put the boat in the water my truck registered a quarter tank of gas. After launching and loading the boat my truck registered a full tank of gas and would not reset or adjust the fuel gauge once it was on a level surface. I found several complaints on the Toyota forum regarding the fuel gauge improperly reading a full tank after being on an incline and not adjusting once on a level surface. I was forced to disconnect the negative battery cable to reset the fuel sensor. Fast forward the truck was at the dealer on 7/28/2025 for the engine replacement. I asked them to look into the fuel gauge sensor issue and was advised that there is a Toyota TSB for the sensor and it needed a computer reflash, but would not do the reflash at their expense. This is a safety issue that if not corrected may cause individuals to run out of gas while in motion on the highways causing the vehicle to stall causing a collision or road hazard.

Frame rusted out causing gas tank to fall off truck while driving. Was sparking while trying to pull of to a safe spot on highway, tank was hanging on by the fuel line. Leaf spring also broke on truck do to rust. Cars were avoiding my truck on highway as sparks were coming from the gas tank shield scrapping the highway. Frame should have been replaced along with gas lines, and leaf springs during the recall in 2012 range. Toyota of york decided to just undercoat spray frame, prior to me purchasing truck from them. They never notified me (the consumer) of the recall that was current on truck.

Transmission or engine has a lag, or dead spot from a complete stop to acceleration, such as leaving a stop light. At times barely noticable, other times it seems the engine is going to die. Dangerous when pulling onto a busy street from a side street. Dealership says "unable to replicate" which is understandable, as it's somewhat intermittent. This appears to be with all model year 2022 and newer Toyota Tundras.

At random times, from a dead stop, there is a significant ‘dead pedal’ issue with my truck when I try to accelerate. This is is followed by a huge surge in power to catch up and it lurches forward. It’s very inconsistent and worries me about turning out into regular traffic at times.

Acceleration hesitation every time I push the accelerator.

Periodic sluggish gas pedal response. Often from a stop when pressing the gas pedal the truck lurches a little forward then slows down as if I took my foot off the pedal right after pressing it. Nearly got rear-ended a couple times.

The vehicle has a hesitation when accelerating or when I turn a corner and then try to accelerate it lags. Had a few incidents where I almost got rear ended due to the issue.

Occasionally, upon coming to a stop or from the stopped position the vehicle briefly hesitates when trying to accelerate cause the vehicle to aggressively jerk once the vehicle begins to accelerate, sometimes leaving you in the middle of an intersection or in a dangerous situation in traffic due to unresponsive acceleration inputs.

Hesitation when pulling out from a stop. Enough of an unplanned delay that it’s dangerous from cross-traffic at an intersection. Complained to dealer and they “updated” the computer and it still happens.

Multiple times a day, when I push on the accelerator there is a delay. I’ve almost been hit a couple of times.

I am experiencing a recurring issue with my 2024 Toyota Tundra’s fuel gauge. Specifically, when the vehicle is parked on an incline, the fuel gauge resets to indicate a full tank, regardless of the actual fuel level. For instance, after parking on a hill with approximately half a tank, the gauge displayed full upon restarting the vehicle.

Anytime I come to a yield/traffic circle and do not have to come to a complete stop, when I push the accelerator there is a hesitation and then the truck lurches forward. It happens quite often when I slow down to 5mph give or take before accelerating again. I would estimate it has happened 50 times since I have owned the truck which I bought with 300 miles on it.

Ran out of fuel on highway due to erroneous fuel guage. Truck when parked on an incline will show a full tank after starting even though gas tank is 3/4 full. Problem has been reported to dealer and no follow up nor resolution has been offered. This event is dangerous and troublesome,.

Fuel pump out after 3 weeks. 4-24-25 three weeks ago 4-07-25 I had an issue with my fuel pump and the Toyota dealer replaced it. I also reported it here at that time. I typed up what the truck did and sent it to y'all before I ever got word of what was wrong. The report from them is not accurate. They stated I had run out of gas and the fuel pump was burnt up. As I stated I lost propulsion but the truck was still running. I will say I also know I had a couple of gallons of gas in it as I added some the day before and I know how far I drove as I put a little extra over the distance I was going and of course it had gas in it since I drove it to the gas station. Anyways they replaced the pump and now 3 weeks later 4-24-25 the new pump is out. The truck acted the same as it did 3 weeks ago and again it wouldn't start after turning it off. I had to have it towed to the dealer again. They confirmed today it was the fuel pump that had gone out. I know I had about a half tank of gas this time.

Throttle lag / hesitation when pushing the gas pedal. This is a very serious issue. There are many many complaints about this issue but the Toyota and the dealer is not doing anything about it. This hesitation has almost caused me several accidents because the gas pedal does not respond. Causing on coming traffic to swerve or brake to avoid me. Let's hope this issue get attention before it's too late. Just google "tundra throttle lag" and see how many Tundra owners have this serious issue.

A low speeds there is a delay in throttle response. If you come to a stop then step on the accelerator, the vehicle has no response for a short period of time where then it may buck or propel itself to catch up with the missed throttle. I recently picked this vehicle up from the dealer and was told there is no remedy for the issue at this time.

2025 Toyota Tundra with 2200 miles. Truck has developed an intermittent lag/hesitation when starting from a stop. At random times, when pulling out into fast moving traffic, hit the pedal to proceed and enter the roadway and it will take a second or two before there is any response from the engine. Oncoming traffic traveling at 50mph are now a second or two closer and need to brake hard to avoid collision. There seems to be a fault between the throttle pedal and the engine. No warning lamps. Difficult to reproduce as it only happens on occasion. Vehicle has not been inspected by a dealership. The issue has been reported to Toyota via online support, message # [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Throttle lag. When I step on the gas pedal, there is a hesitation or lag which the truck doesn't move forward when asked. Very, very dangerous when entering traffic. Almost caused an accident. Not good. This must be addressed before someone gets hurt or killed. This is no joke and should be taken seriously. I hope this doesn't get ignored as this is a serious problem.

There is clear hesitation and lurching when accelerating.

Truck shut off while driving fuel pump connector in the tank was melted and could have started a fire. Was told my Tundra doesn’t fall under the recall but is having the same problem.
