Other Fuel System Problems of Toyota Tundra - part 2

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.

I bought the vehicle new in November 2025. 2026 Toyota tubdra trd sr5. In the first week I noticed a lot of jerking and shaking. I brought it to the dealer and was told it was a break in period and it should go away. I’ve had the truck in the shop 5-6 times since and the jerking and shaking hasn’t gone away. I’m at 6300 miles now. The dealer won’t even respond to me anymore. The only way to make the jerking go away is to step on the gas pedal harder but this has become extremely dangerous because it’s forcing me to go faster than I would like, especially in school zones. The dealers say that it’s the truck running very low rpm’s to maximize fuel efficiency and also because there are 10 gears but is that’s the case than why isn’t everyone experiencing it. It’s worse on cold mornings (40 or below) but it’s almost like the truck needs an hour or two to warm up. Even then it’s still jerking. My guess is that the truck doesn’t know what gear it’s supposed to be in but 4th or 5th gear are the worst where the truck hesitates and jerks. I’ve been told to run it in sport mode but that doesn’t help. I’m finding more and more complaints about this online with the Toyota Tundra sr5’s and I’m part of numerous groups. Someone needs to step in because no one should have to go through this and it’s very unsafe to have to push the gas pedal down harder to make the jerking go away. Thank you for your time.

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.

Began experiencing long cranking, difficulty starting, then rough idling. Started researching online and found recalls for 2018 -2019 flex fuel 5. 7 Tundras. My 2017 is also a flex fuel 5. 7 with exactly the same issue. Dealer says 2017 not covered. I had to pay over $2000 to have the fuel pump replaced, ecm reprogrammed. I don’t understand why 2017 was not included in the recall. Please NHTSA consider extending this recall to 2017. I am reading numerous complaints on this website about the same issue from owners of 2017 flex fuel Tundras.

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.

November 2025 notice there was issue with engine February 24 2026 serviced for engine April 13 2026 serviced for engine may 05 2026 serviced for engine June 15,2026 serviced for engine no remedy problem still presist.

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.

After I come to stop at a light or a stop sign, when I press the accelerator the truck lurches out into the intersection then stops and the truck will not move for 1-3 seconds even though I am pressing the gas pedal. When it finally responds, the truck jumps or lurches forward. Each time this happens I am almost hit and people have to drive around me. I have been almost hit like 50 times. This is a huge safety issue.

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.

Problem - throttle lag/hesitation/lurch. Truck won't go when throttle is pressed for a couple seconds cold or hot. Mentioned the problem on my 5000 mile service. Service tech said he could not reproduce the problem but happens with my drives 95% of the time. No warning lights have appeared.

Unknown. Intermittently when merging into highway traffic from the onramp, the truck will stall and I will lose acceleration. There will be a loss in power and the truck speed will not change. Instead it will just coast with no ability to change speed. I have owned the truck for 1 year and 3months. I advised the dealer and they can not duplicate the issue.

1-2 second period of no throttle response from a rolling stop, then a sudden lurch of acceleration many times onto a now busy intersection.

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.

Vehicle shutting down while driving (3 incidents) diagnostic codes p0a3f21, p1cad49, p0a3f1f, and p1c5d19 multiple failed repair attempts Toyota's refusal to address safety defect.

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 .

The dealership and Toyota engagement center refused to service the 2 recalls that was critical for the truck since October 2025. It was supposed to be including frame replacement and other parts but Toyota engagement decided to active buy back option and took advantage of low offer to solve the matter which I don't accept.
