There are 14 owner-reported engine complaints for the 2025 Toyota Tundrain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
My Tundra Truck is having throttle lag. I pull out into traffic and there is no power. I put the throttle all the way to the floor and still nothing. After 2 to 3 seconds the engine starts to slowly throttling up, but very slow and no turbo. This has happened at least 15 times now since I owed it in July of 2025. That scared me so bad I now have it at the dealer for diagnostics. They had better fix it, I almost got into a wreck.
Complete engine failure on 2025 Tundra. Left me stranded on the side of the highway.
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 u press the gas the speed hesitates sometimes
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.
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.
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.
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.
Bad hesitation when first depressing the throttle. I drive the truck in the Sport + mode and it does help.
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.
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
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.
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.
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.
