2025 TOYOTA TUNDRA Engine Problems

Vehicle stalls after stopping often

Laggy throttle response, always a significant delay. This is dangerous, especially during heavy traffic situations. Drivers seat constantly pops and cracks under acceleration or braking.

Complete engine failure on 2025 Tundra. Left me stranded on the side of the highway.

Throttle response lag then sudden surge. Occurs occasionally not constant. Press on accelerator and no response, the next it’s wanting to take off. In stop and go traffic, the lag may not let vehicle get up to speed like merging, then with the surge, could accelerate too quickly reducing reaction time and cause an accident.

Continue getting a 1-2 second delay when accelerating from a dead stop after pushing on gas pedal with normal acceleration- not just an “lead foot” acceleration trying to quickly clear my intersection & merge into traffic. Happens when engine is at normal operating system or just pulling out of my neighborhood onto a 45mph road on a normal temp day.

When accelerating from a standstill, the car hesitates for 1 to 2 seconds after I press the accelerator pedal. This is a safety concern, especially when merging onto the highway (we have stoplight-controlled merge lanes where I live), where accelerating the vehicle is essential to a safe merge into traffic going 65+ mph. There have been no warning lamps.

There’s a delay in throttle response. Especially when making a turn across traffic. Throttle would not respond for at least 1 to 2 seconds. Even at full throttle the truck did not respond while cars were coming towards me. This has happened to several tundra owners. Check Facebook tundra group and you’ll find others with same issue.

Advanced driving system - Truck with leave a lane unprovoked and will fight you to recover manually. I have another Toyota with the same system (2024 Grand Highlander) and it works perfect. Not confirmed by dealer yet. It will be next week. Not inspected yet. Automatic lane centering just stops working, display changes to "not tracking'. Blue lines disappear on display. Truck has done this since new. I was very disappointed when I first used it since I expected it to work like our Highlander.

Bad hesitation when first depressing the throttle. I drive the truck in the Sport + mode and it does help.

The gas pedal has no response when coming to a stop and pushing on the gas pedal. Multiple times I come to a stop, push the gas, no response, 1-3 seconds later; the vehicle jerks forward. On occasion it has nearly lead to an accident and I do not feel safe in my vehicle.

The vehicle has a recurring safety-related defect where there is a long, unpredictable pause (1–3 seconds) between pressing the accelerator from a stop and the truck actually accelerating. This hesitation occurs when pulling away from a stop sign, traffic light, or after braking to a stop in traffic, and is not normal throttle response or turbo lag. During this delay, the engine revs slightly but the truck does not move, creating a dangerous situation where the vehicle fails to respond when expected, especially in intersections or when merging. After the pause, the truck often surges forward abruptly, which can cause jerking and loss of control.

when u press the gas the speed hesitates sometimes

Throttle lag truck stalls out when you try to go from a stop. It will cause an accident if this is not fixed. Also engines keep blowing up with out the hybrid system your truck will not have any port to get over to a safe spot on the road. Toyota is replacing engines but the ones they are putting in the trucks are the same ones that are failing.

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 continuously experience throttle delay when accelerating from a stop. This has almost led to being hit several times when pulling out into an intersection. This seems to be a common issue for newer Tundras

I’ve noticed that my Toyota Tundra occasionally fails to start moving from a complete stop at a light or stop sign and hesitates. I’ve pressed the gas pedal all the way down, but it doesn’t respond. It usually takes a second attempt before it will move from a stopped position. This first happened during my first week of owning the truck and has occurred a few more times since. I didn’t think much of it at first, but it happened again while I was stopped on an incline in a right-turn yield lane. I released the brake, and when I pressed the gas pedal, nothing happened—the truck even felt like it was rolling backward. I floored the gas, and after a few seconds, it finally took off. I started looking online and found that many others have reported the same issue. There’s even a YouTube video from someone who experienced...

When making a left turn or pulling off from stop light the truck almost stalls out. Very dangerous when traffic is coming. Need a fix ASAP. Could cost people their lives.

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.

Engine maintenance bearing failed at highway speed. I was able to coast to the roadside because there was no other traffic. Engine would not restart.

Vehicle experiences electronic throttle lag that causes the vehicle to not accelerate when pressing on the accelerator pedal. Then it accelerates excessively and nearly uncontrollably before coming under control.

The vehicle will stall or lag during acceleration from stop or during regular driving while trying to accelerate. Happens continuously throughout ownership of the vehicle.

Making a right turn from a stop. I pressed the accelerator and the vehicle barely moved. Cars were coming in my direction and I had to move. I let off the accelerator quickly pressed the accelerator again. The vehicle did start moving at normal rate. This first attempt was very concerning and almost caused me to get in an accident.

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.

There is an interment issue where the vehicle fails to accelerate from a stop when accelerator is applied. This issue is present in my current vehicle and my previous 2023 tundra. I have brought up concerns to the dealer and manufacturer and am told every time that the concern cannot be duplicated, but I feel that it is going to lead to a crash not only for me but other owners

I’ve notice that when coming to a stop or yield when you press the gas pedal to go or continue driving there’s a lag or delay. This has happened more than 4-5 times since I purchased the truck on December 23, 2024. The last time it happened was last Saturday August 9, 2025. Truck was on sport mode, Auto Stop/Start was off. I’m at a light waiting to make a right turn, when I pressed the gas pedal to go it went forward and felt like I slammed the brakes. I had to take my foot off the gas pedal, brake, then gas it up again to go. It is a little scary because this could cause an accident. I’ve taken my truck to the dealership about this, but they said they can’t do anything about it because they cannot recreate the issue.

Upon starting the vehicle on 8/6/2025 i received multiple warnings: advanced ultrasonic detecting and ranging system malfunction, Pre-Collision system malfunction, Parking Brake system malfunction, Check engine ECM malfunction, Vehicle stability control system malfunction Secondary collison brake system malfunction, It now take almost a mile on level ground to reach 45 mph. This occurred without warning. the vehicle was ok the day before when I parked it.

When you come to the complete stop if the AC on or not on the engine vibrate, and when I called Toyota dealership, there is no answers for it

Only had the truck for 3 weeks, I'm starting to feel a lag when accelerating. I thought it was just the turbo lagging, but it may be the gas pedal communicating as I barely ease into it.

While merging from a stop or slow roll, once the accelerator is pushed the vehicle hesitates for 3-5 seconds. Once the vehicle starts powering up it lurches forward and you have to stop accelerating to keep control.

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.

Vehicle shudders and hesitates during acceleration from a stop and at speed. Vehicle feels like it is trying to find the correct gear which is causing the turbos to release boost pressure prematurely.

I was driving about 50 MPH and suddenly my check engine light came on and the truck died and would not start. I was told that the engine failed and will need to be replaced.
