Other Fuel System Problems of Toyota Tundra - part 1

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.

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.

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.

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.

Ever since I got this truck, I’ve experienced intermittent hesitation/lag when accelerating from a stop. I’ve reported it to the dealer several times and am always told they cannot reproduce. The problem was not improved after the engine replacement. This is dangerous - when pulling into traffic I cannot always count on my truck actually moving when I press the accelerator.

The truck has a hesitation to start from stop/slow state. This is concerning because when I start to accelerate, sometimes it doesn’t want to go for a 1-2 second time period making it unsafe to pull into traffic. It is sporadic and seems to happen more when I start and stop in quick succession.

Throttle lag. When stopped at a stop sign, I attempted to accelerate and when I pressed the pedal, the vehicle didn’t respond. I had to release the gas pedal, wait a second, then attempt to accelerate again. This time it responded.

Standard vehicle components failed. My 2008 Tundra [VIN [xxx] ] was inspected in Nov 2017 under hof/wep, passed with crc applied, but now has a 2-finger-wide perforation in the frame and rusted through the gas tank support—a clear safety defect in a salt state like maryland. The undercoating failed prematurely; I need goodwill frame replacement or buyback per the $3. 4b settlement’s spirit. ” (reference the 2017 class action, case no. 3:14-cv-03538). Toyota brand engagement center has refused my request for repair or replacement or buy back. They also refused to provide written refusal. They admitted to recording the conversation, but refused my request for a copy or to record the call myself. There is literally no rust on any other portion of my truck as it is garage kept. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The throttle lag is a major safety concern. When pulling way from a stop there is a huge delay in throttle response. This is consistent and has caused me to have several close incidents and nearly an accident. This is a programming issue that Toyota needs to address.

Throttle response occasionally drops out. Lag when trying to accelerate from a stop, then kicks in and the truck surges forward.

Throttle delay/ hesitation that is very unpredictable.

While driving under normal conditions, my 2023 Toyota Tundra trd pro hybrid experienced a sudden and severe loss of propulsion. The vehicle abruptly entered fail-safe (limp) mode and would not accelerate beyond approximately 5–10 mph. This occurred without warning and created an immediate safety hazard in traffic. Multiple warning messages illuminated simultaneously, including: hybrid system malfunction, check engine, Smart stop system malfunction, and advanced ultrasonic detection malfunction. The hybrid system effectively shut down and the vehicle could not maintain normal road speed. I brought the vehicle to a Toyota dealership. The dealership performed only ecm and hybrid ecu software updates and cleared codes. No mechanical inspection, oil pressure analysis, particulate inspection, turbo system evaluation, hybrid motor synchronization testing, or engineering-level diagnostics were performed. Toyota corporate subsequently stated that the software update was the “final” resolution and declined further diagnostics. I was advised to return to the dealership if the issue reoccurs. This failure mode matches the documented loss-of-propulsion behavior described in Toyota’s v35a engine machining-defect recall (sudden power loss, limp mode, cascading system failures). Hybrid models are currently excluded despite using the same engine platform and exhibiting identical symptoms. Sudden loss of propulsion at road speed presents a serious crash risk. This appears to be a safety-related defect that is not being adequately investigated or remedied for hybrid models.

Vehicle randomly stalls or experiences throttle lag/acceleration hesitation particularly when trying to accelerate quickly through intersections and while turning. Almost seems as if the vehicle loses power all together and then quickly comes back.

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.

I am writing to report a serious issue with my vehicle’s throttle response. When accelerating from a stop, the vehicle consistently hesitates and feels as though it may stall, leaving me vulnerable in traffic or at intersections. This problem has already resulted in three very close calls, two of which required police involvement. I no longer feel safe operating this vehicle under these conditions. I have attempted to trade out of the vehicle, but the offers I’ve received have been significantly reduced due to the widely known nature of this issue. Please advise on the next steps to address this matter. Safety is my top priority, and I believe this situation requires immediate attention. Thank you for your prompt response.

This vehicle has terrible throttle lag/delay, sometimes lasting up to 4 seconds. This poses a serious threat while pulling out in traffic.

The vehicle does not predictably respond to throttle inputs (if it responds at all), when you come off the brake pedal it will begin rolling at "idle" speed as normal but when you begin to increase throttle input nothing will happen for several very important seconds as you roll into an intersection or need the vehicle to accelerate to maneuver. This had happened multiple times before scheduling service appointments. The day before my appointment while trying to make a right hand turn from eb 13st st in lemont IL to sb bell rd, I had stopped for the red light, verified clearance to make the turn, and began my maneuver. Once I came off the brake pedal the vehicle began to roll into the intersection but as I began to turn the vehicle and try to accelerate though the turn it did not respond whatsoever. I desperately tried to roll my vehicle into the ditch to make space the incoming vehicles to minimize danger, but had no power to do so and was violently t-boned. The vehicle was brought to the dealer for their analysis, the service manager initially claimed "I know exactly what it is" and continued to ask questions that prompted previous knowledge of this issue including what speeds and conditions it will occur at. . Two weeks later the vehicle is "ready" and the manager claims the "eprom" had 2 pages of codes in it and that "got rid of the hesitation" I take him for a test drive with me and was able to recreate the issue a few times at which point he said "I understand your frustration with the truck but its a good truck" I drove the truck a few days and continued to experience dangerous and unpredictable delays in throttle response, one of which almost caused me to be rear-ended by a semi while merging from IL-rt83 onto I-55 nb the vehicle has been left behind on a family road trip as it is not safe enough for my family. In hind sight I wish I had the opportunity to submit it to NHTSA for examination after the crash rather than than Toyota. Please do something.

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