2025 Toyota Tundra Engine Problems

Mileage when the problem started

Owner reports

Selected complaints filed with NHTSA by 2025 Toyota Tundra owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2025 Toyota Tundra. The contact stated that the vehicle was leaking oil. There was no warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the gasket needed to be replaced. The vehicle was not repaired. The contact requested a buyback. The manufacturer was not notified of the failure. The failure mileage was approximately 34,000.

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. …

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. …

On July 20, the vehicle experienced a catastrophic mechanical failure resulting in a total engine seizure while operating. The failure caused an immediate, sudden loss of motive power, forcing the vehicle to become completely immobilized on the Interstate highway. This unexpected loss of propulsion created an immediate and severe highway crash hazard for myself and surrounding traffic. The vehicle was towed to an authorized Toyota dealership on July 20 under the 5-year/60,000-mile factory powertrain warranty. The vehicle has remained completely out of service since that date. The dealership has tentatively scheduled the engine repair and replacement to begin on August 24 or 25, meaning the vehicle will have been non-operational and out of service for over 35 consecutive days before repairs even commence.

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 # [redacted]

My truck showed "Hybrid Engine Malfunction contact dealer" upon start up, then "Reduced Engine Performance Check Engine" warnings. I was not warned that I should not drive at all so I took my son to school. As I was driving home up a hill around 35 mph the temperature gauge began to climb fast towards the upper limit. At the upper red limit the car warned "Engine Overheating Stop Immediately" and I pulled over. The engine began smoking as I pulled over. I have an aftermarket Air Intake for the twin turbo and an aftermarket cat-back exhaust system but neither of these parts could have caused dramatic overheating of the main engine and failure of the hybrid system. Events happened over the span of about 15 min driving from start up to breakdown.

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.

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.

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

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.
