2025 Toyota Tundra Engine Problems

Toyota Tundra 2025 Limited stalled at highway speeds. The vehicle flashed "Parking Brake Support" message, but dealer says it has to do with an engine failure. Vehicle came to a grinding stop and would only advance in short spurts before dying on the side of the road. I was in the left lane of a major highway during rush hour. Luckily, traffic was behind me, and I was able to limp to the shoulder before traffic arrived. I noticed nothing prior. A loose gas cap may have prompted the system to send failure message. I haven't heard yet why it stalled. But my safety was definitely put at risk, and I was lucky to not be rearended

Have owned the 2025 Toyota Tundra for about 18 months. Multiple instances of delayed acceleration when stopped or almost stopped, sometimes as much as 3 or 4 seconds. Last time was in early June, 2026. This is very dangerous because when I pull out into an intersection it will start to go but then lose all power for a few seconds with traffic coming behind me. This is something Toyota needs to look into.

I have experienced a severe hesitation or delay in acceleration when accelerating from a stop or near-stop condition. While the issue has only occurred a few times over the past several months, on multiple occasions it happened while merging into traffic and nearly resulted in an accident. Toyota has issued Technical Service Bulletin (TSB-0032-26) addressing this condition. However, when I brought my vehicle to the dealership, Toyota documented that they were unable to reproduce or confirm the hesitation, and no repair was performed. This defect presents a significant safety risk. Unexpected loss of acceleration during traffic merges, intersections, or other situations requiring immediate power can place drivers and passengers in danger and could lead to serious injury or death. Given the safety implications and the fact that the remedy appears to be a software update requiring less than an hour to perform, I believe this issue warrants a formal safety recall rather than a voluntary Technical Service Bulletin. I urge NHTSA to investigate this matter and require Toyota to provide a recall remedy for all affected vehicles.

When coming to a rolling or quick stop and then attempting to maneuver across traffic, my truck hesitates for about a full second before accelerating. This delay can create a dangerous situation for myself, other drivers, and pedestrians. I believe this is a safety issue that Toyota needs to address promptly.

The issue I’m having is the transmission/engine when it comes to the hesitation for stopping and either slowing down or just a rolling stop. Sometime I would feel like I need to precisely control the brake pedal in order to go smooth stop, but no. It feels like it’s ’jumping’ in mini burst. I have the hybrid engine of the V35A-FTS. I did check for recalls but nothing found but found a TSB from Toyota T-SB-0032-26, but my hybrid is not covered, only the non-hybrid Tundra. Please help. Thanks

I was crossing two lanes of a 4-lane highway from a stop. I floored the accelerator to cross traffic and the truck hesitated for approximately 1-2 seconds in the middle of the highway before finally accelerating. During this time I was completely exposed to oncoming traffic with no ability to move the vehicle. This is not the first time I have experienced throttle hesitation on this vehicle but this was by far the most dangerous instance. The truck has ~17,000 miles and is a 2025 model year

My truck engine seized at highway speeds on 4/29/2026. Machining debris seized to the engine’s bearings causing oil to dump from the engine and the engine to completely seize. This is the same issue that NHSTA forced Toyota to issue a recall on 2022-2024 Toyota Tundras.

I am seeking a case review regarding a persistent and unresolved drivetrain issue with my 2025 Toyota Tundra (non-hybrid) that began immediately following a dealership service visit and has continued for over one month without resolution despite multiple repair attempts. Since that time, the vehicle has exhibited consistent transmission-related defects including failure to shift properly into higher gears (notably not reaching 10th gear at highway speeds), RPM hanging under light throttle, delayed acceleration followed by sudden surges in power, and harsh or erratic downshifting that causes the vehicle to lurch forward when slowing to a stop. The vehicle also demonstrates inconsistent torque delivery, where boost builds but power is not transferred until a delayed and abrupt engagement occurs. These issues are most pronounced during normal highway driving conditions and significantly impair drivability and safety, particularly when merging or maintaining speed. I have brought the vehicle to multiple Toyota dealerships for inspection, where diagnostic scans have not produced any fault codes and I have repeatedly been told the vehicle is operating “within normal parameters,” despite the ongoing and reproducible performance issues. The dealerships have been unable to replicate or resolve the problem, and I have received inconsistent explanations ranging from normal operation to speculative driving pattern causes. I have an active case open with Toyota corporate, but after a month of delays, lack of diagnosis, and no corrective action, the issue remains unresolved. Given the ongoing safety concerns, repeated repair attempts, and inability of Toyota to identify or fix the defect, I am now left without a resolution & am instructed to drive the vehicle despite drivetrain issues.

I am reporting multiple safety-related defects on my 2025 Toyota Tundra (approx. 18.5k miles, purchased 07/25). Toyota has been made aware and has not resolved these issues. The most serious defect is deterioration of the driver-side air intake housing. While replacing the air filters, I observed the airbox shedding internal material directly onto the engine air filter. This is not external debris and there are no signs of rodent intrusion, indicating internal component breakdown. This vehicle shares the V35A engine platform, which is subject to recall for debris contamination leading to main bearing failure, engine stall, and loss of drive power. The presence of internally generated debris upstream of the engine creates a credible risk of engine damage or sudden failure while driving. Toyota’s recall documentation confirms debris contamination can cause engine stall and loss of drive power. The windshield cracked during extreme cold weather. The crack originated near the lower edge at the wiper/cowl interface and propagated upward in a pattern consistent with stress or thermal failure, not impact, affecting visibility and structural integrity. Additionally, the lower front bumper trim cracked without meaningful impact, and the rear bumper failed under minimal load in cold conditions. These failures indicate material brittleness and raise concern for reduced crash protection and increased risk of injury in a collision. Other issues include driver-side seat trim cracking and premature paint and trim degradation. Similar failures, including windshield cracking, trim failure, and cold-weather brittleness, are widely reported by other 2022+ Tundra owners, indicating a potential systemic defect. Given the known engine recall and active internal material degradation in the intake system, there is a credible safety risk of engine stall, sudden loss of power at speed, reduced visibility, and increased injury risk due to compromised bumper integrity.

Dead pedal incidents. At least 4 times in the 6months of ownership, I've experienced where when you press on the gas to go, there is no acceleration for approx 2 seconds. Its almost caused an accident 2x of the 4x times its happened. I feel it may be related to the transmission. Prior to this truck I had a 22' Lexus LS500 Fsport which I think also has the 10 speed trans and twice experienced similar conditions. It kind of feels like the trans is slow in downshifting, trying to figure out where it needs to be.

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.

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.

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.

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.

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.

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.

Incident

Jan 15, 2026

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.

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.
