2024 Toyota Tundra Power Train

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.

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.

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.

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

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.

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.

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

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.

Vehicle lag / hesitation after pressing the gas pedal.

Throttle lag/hesitation when making a right hand turn after a stop. Truck was moving after taking my foot off the break to advance my vehicle to get a clear line of sight due to cars parked on the roadway. Once line of sight was clear there was a lag/hesitation after stepping on the accelerator

Vehicle periodically fails to accelerate from a stop. Causing a 2-3 second delay in throttle response. This has been happening since new.

Severe throttle hesitation/lag when accelerating from a rolling stop for at least 2 seconds. This has happened at least 20 times since purchasing the vehicle in September 2024. On a few occasions, I had to abort acceleration completely to avoid an accident. It’s a very dangerous situation, especially with my family in the vehicle. I have noticed that putting the gear selector into ‘S’ manual mode seems to help considerably, therefore, this appears to be some form of a TCM problem. I took the vehicle to the dealer and they said that it performs like similar trucks. This problem is embarrassing and dangerous, and it needs an expeditious resolution.

Transmission hesitation when starting from a stop/ stop sign. Will take 1-2 seconds before transmission kicks in after coming to a stop and then proceeding with no one else in the intersection. Happens about 95% of the time. Has put me in a few near- misses where I expected the truck to get out before oncoming traffic. a similar issue occurs when starting on an incline- press the accelerator and it takes a few seconds for the transmission to catch up. Ongoing issue since about 7, 000 miles. Seems to be getting worse

My 2024 Toyota Tundra Platinum Non/Hybrid regularly stalls when trying to accelerate from a stop. This happens every day. When accelerating from a stop, the truck takes several seconds to move the truck to the point of almost being hit by oncoming traffic that I should have plenty of time to turn in front of. This is a very common problem among the Toyota Tundra community. I’ve brought this up to my dealer several times. They document it and call it normal operation.

Complete engine failure at 62,000 miles. This has been an ongoing problem with Toyota tundras with a V6 twin turbo. I was told that the dealership that the 2024 models were not affected by the known manufacturing defect. There’s been a complete recall of the 2022 and the 2023 models. This could be a safety issue if I was driving on the highway and had the engine failure. The dealer confirmed that this is an ongoing issue, and there may be an expansion of the recall.

There is an occasional lag between when I press the accelerator to when the engine actually revs up. It's usually fairly minor at less than 1 second but today I was making a left turn on a busy road and the lag time was closer to 2-3 seconds and almost caused me to get T boned by two cars coming from my left. It happens from still and from slight rolling. Today I was completely stopped. I hit the gas and all it gave me was enough to roll me into oncoming traffic and then I was stuck in their lanes until it finally kicked in and carried me on through the turn. Apparently this is a known issue with a TSB for 22 and 23 year models. This is extremely dangerous and should warrant a recall before someone gets killed.

My motor shut off while I was driving. I had to have it towed to the dealership and they diagnosed the problem as a failed. Connection rod bearing. This requires an engine replacement to remedy the situation.

Transmission is shifting hard

When I shift out of N or P into drive there is loud and aggressive clunk. Like the tranny is gonna drop out the bottom! It’s a tight grip, the shifter doesn’t want to move. Potential to run someone in a car park or walking down the sidewalk.

My truck, which has a build date of July 2024, is having numerous on going episodes of hesitation and throttle lag when transitioning from a complete, or nearly complete stop. The truck was purchased in early October 2024. The hesitation was not noticeable at first. It began presenting itself after about 6 weeks of ownership and 1000 miles. Today, with 4200 miles on the vehicle, it hesitated twice on a 15 mile city trip. There is no rhyme or reason as to when it may present itself...such as warm/cold outside, vehicle warmed up or still cold, or from a rolling or a dead stop. It does appear to be getting more frequent with longer delays in throttle response. I consider this to be a high priority safety issue that needs to be addressed immediately. I have never experienced this condition in a vehicle before and I have purchased about 15 new vehicles in my lifetime. I am now scheduling an appointment for this matter to be addressed with the dealership.

The truck has a hesitation with the throttle and does not move for a few seconds causing a safety concern.0

Vehicle has a persistent transmission issue which causes hesitation/shuddering under acceleration and cruising rpms. Toyota claims issue is software related after 5 trips to dealer. On this particular occasion the vehicle downshifted erratically climbing a steep roadway causing a loss of control in wet conditions activating the vehicle stability control. Vehicle was brought to dealer and Toyota Brand Engagement was notified requesting a remedy.

On light acceleration to maintain speed or flow of traffic, there is a drivetrain shudder the reverberates through the entire truck. It most noticeable when coming up grades of any kind, but can be replicated in most driving situations.

I was pulling out into traffic. Gave the truck some gas and nothing. For a second or two it was at idle although I was giving it gas. The hesitation caused others to slam on brakes.

Acceleration decreased randomly while starting from a dead stop. Loss of power when trying to pull away from the line
