My vehicle is equipped with the same V35A-FTS 3.4L Twin-Turbo V6 engine and #1 main bearing assembly that is currently under federal recall for catastrophic engine failure (Recalls 24V-381 and 25V-767). Despite the shared mechanical defect of machining debris and bearing tolerances, Toyota has excluded the i-FORCE MAX Hybrid models based on the assumption that the electric motor provides sufficient 'limp home' capability. I believe this is a critical safety oversight, as a sudden internal combustion engine seizure at highway speeds creates an unpredictable loss of motive power that a small hybrid battery cannot safely manage in high-speed traffic. I am filing this to urge the NHTSA to expand the recall scope to include hybrids, as the primary power source is fundamentally defective and prone to stalling without warning

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 contact owns a 2024 Toyota Tundra. The contact stated that the vehicle had consistently experienced a throttle lag while driving from a complete stop and while decelerating. Additionally, the contact stated that while accelerating from a complete stop at an intersection, the vehicle hesitated to respond and then lurched forward while responding. There was no warning light illuminated. The failure had been recurring intermittently. The vehicle was taken to the dealer, where an unknown repair was performed; however, the failure persisted. The dealer was notified of the failure. The contact stated that the dealer had advised that data from the Event Data Recorder(EDR) had been erased while in the process of correcting the throttle lag. The vehicle was not repaired. Additionally, the contact learned that a Class Action Lawsuit was filed in the State of Vermont due to the failure. The manufacturer was notified of the failure. The failure mileage was approximately 100.

I am an automotive engineer. I have been involved with vehicle development programs in the disabled vehicle conversion community for over two decades and have numerous patents in that space. I have been involved with vehicle testing and calibration as well. My vehicle demonstrates a SIGNIFICANT HESITATION when the accelerator is pressed that is not consistent. I live in a roundabout dense location where timing an entry into a roundabout is easy using a normal vehicle. The 1 to 2 second hesitation where there is throttle input and no action at all from the vehicle (engine does not rev, no motive power observed) is very dangerous. I took this up with Toyota and my vehicle was checked out and "learning transmission" memory was wiped clean with me being the only driver was the remedy. The issue got better for a short time but is back and this morning I pulled out thinking there was plenty of time in front of a bus a good distance away and the lack of motive power for a full second or two resulted in a near miss. This vehicle has about 20,000 miles and was purchased by me new. There are NO WARNING LAMPS, and no DTCs thrown when this happens. I have seen several videos where people cite the same experience and a website where there is a class action lawsuit in place regarding this issue. This is completely separate from the engine recall issue. I feel as though this issue is a significant safety risk.

Throttle lag, takes a couple of seconds for the truck to register me pressing on the gas before jolting forward. Not only frustrating but dangerous.

- Converse, TX, USA

Numerous times (4-5) the truck has failed to accelerate from a rolling stop and/or a full stop. One time recently, I stopped and quickly tried to turn left onto another road. As I accelerated, the engine lagged and the truck felt as if it would stall. In all instances, the transmission seems as if it has not downshifted into 1st gear... and appears as if it is stuck in 3rd or 4th gear and the engine struggles to keep up. No warning lights or messages appeared in any of the instances. I am taking it to the dealer for them to look at.

- West Olive, MI, USA

I was stopped and went to pull out of the gas station. With my foot on the throttle I pull out. And it would not accelerate. I had to pump the gas pedal I almost got hit by oncoming traffic due to the lack of acceleration this has happened multiple times Very dangerous

- Reedsville , PA, USA

Extreme lag response from stop on numerous occasions causing vehicle to not move for well over 1-2 seconds. Seems to happen mostly within 5 mins of start up. Had to stop slightly out in intersections several times due to this lag not allowing me to proceed safely. It doesn-??t sputter at all, it just doesn-??t move

- Berlin Center, OH, USA

I was at a stop sign making a left turn across four lanes of travel. I had a gap in traffic with ample time to make the left turn so I pressed on the gas pedal to begin the turn. The vehicle did not move forward upon me pressing the gas pedal. After about one second the vehicle finally moved. At that point cross traffic was closing in so I pressed the gas pedal to the floor. The vehicle lurched forward and the rear end broke loose causing me to fishtail the vehicle while making the turn. This delay in acceleration put me and my family at risk of being struck by oncoming traffic. The delay in acceleration caused me to mismanage the throttle sending the vehicle into an out of control turn which could have resulted in a crash had I not been able to regain control. I presented this information to the dealership mechanic and they told me that-??s just how the gas pedals work in the tundra. That is not an acceptable answer. I paid too much for this vehicle for it to not be safe to drive.

- Queen Creek, AZ, USA

Like most other third gen tundra owners, I experience a significant delay at random between pressing the throttle and actual vehicle movement. Often in unsafe situations, such as in traffic or at intersections, the vehicle will not move for 1-5 seconds upon pressing the throttle/pedal. When it finally does move, it will jump forward, startling passengers. This is a clear safety concern that occurs across Tundra 3rd gen models that Toyota has not addressed. I have personally been in several situations where this delay carried a risk of an accident. This has occurred since the truck is new. It now has 30k miles and is meticulously maintained.

Transmission does not shift into gear after accelerating from a brief or rolling stop.

- Ridgefield , WA, USA

When at a complete stop, going to pull out, or continue driving, there is a noticable lag to the acceleration. It sometimes does nothing for a few seconds before acceleration. If backing up, then switching to drive, .there is a delay and or a small jerk motion before the vehicle accelerates. This has caused issues when pulling out and vehicles are coming at normal speeds with plenty of time to pull out. The delay has almost caused several accidents.

- Troy, OH, USA

Throttle hesitation. Seems to be a widely experienced issue with many third gen tundra owners. Press the gas, expecting the truck to drive, but it just lags a few seconds, then will finally engage and begin driving. Has put me in some close calls in traffic.

- Clarksville, TN, USA

I have had an issue several times which nearly resulted in a traffic accident. The truck has a sudden loss of acceleration where the gas pedal is completely dead. It last a few seconds and then goes back to normal. This has nearly caused several accidents where I could not properly accelerate while traffic was heading in my direction. After talking with other Tundra owners, I am not the only one with this issue. This needs immediate attention. If it is not fixed as soon as possible, I fear that someone will get seriously injured or killed. Please take this matter seriously. I suspect it may have something to do with the pre collision sensor system on the truck. It seems that it happens when there is a slight grade or dip in the road. Perhaps the sensors are at a lower angle due to the dip, making it think there is an object it will hit. The Toyota service centers don-??t appear to know why this is happening and cannot reproduce the issue in a short visit.

On Sunday November 30th, I was driving my 2024 Tundra with 30k miles on highway AZ-260 on my way back home to Phoenix. The stretch between Forest Lakes and Payson has an altitude drop of 2500 feet with many areas having a 7% drop. During this drive, my engine shut down with no warning while I was going 65 MPH on a mountain highway with a 7% decline in altitude. The truck had 5 people in it with no power brakes, no engine and going 65 MPH downhill. There was no warning at all. We were able to stop at a safe spot and called a tow truck. The engine started making a loud clanking noise. We had to arrange a ride for all five of us from Payson to Phoenix (~100 miles). This was a very scary situation and it left us shaken. This could have been catastrophic for an inexperienced driver. The truck is currently at AutoNation Toyota Tempe. It has been there for 5 weeks. The dealership told me it needed a new engine. I have now received the official letter mailed to me about the recall. I also called Toyota Corporate and they told me a remedy is not yet available. Not sure how long this is going to take for it to be resolved, but its very frustrating purchasing a new vehicle and having this issue. Any help would be appreciated. The Tundra is still under the factory warranty, plus I also purchased the Toyota extended warranty and Toyota maintenance package.

Throttle lag/hesitation. When pressing the gas pedal from a stop nothing happens for more than 5 seconds or longer. There is significant lag before the vehicle will accelerate.

- Arlington, VA, USA

Component: Electrical Harness + Vehicle Shakiness Problem: Car would enter LIMP mode randomly and shut the car down to 18 MPH and can cause accidents anywhere, especially in highway where speed limits are 65+. Car also now starts shaking violently when 48 MPH is reached which is a safety concern. Reproduce: First turn taking into dealer they found issue then -??disappeared-?? and they could not reproduce, went in again and they produced it then said that I tried tampering the engine then got corporate involved and they paid all of it. Now they are ghosting me and will not check out the shakiness. Inspected: Only by Summit Toyota Dealership (Akron Ohio) Warning Lamps: Only appeared after issue happened and disappeared when first issue was solved.

- Wadsworth, OH, USA

You step on accelerator and it doesn-??t accelerate-?? it lags and almost caused accident more than 4 times! Throttle body won-??t open up and go. I feel they need to remap the system.

- Winston Salem, NC, USA

When coming to a stop and then trying to accelerate to turn into a street I get an abnormal amount of throttle lag. There-??s even times it seems to lag and then registers that I am trying to accelerate quickly causing me to -??burn out-?? while I-??m turning and no I am not accelerating crazy. There-??s been a few close calls where I almost lose control of the vehicle.

- San Antonio, TX, USA

When slowing down to a stop but not stopping completely then speeding up to enter another street or an intersection there is a 1-2 second hesitation before the truck reacts and actually moves. This is very scary and dangerous as it can cause an accident with oncoming traffic in certain situations. Toyota knows about this and does not have a fix for this defect.
