2025 Toyota Tundra engine problems

“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.”

“Mutplie times am have a delay on the accrelations have taken it to the dealer to be told thats just how the hybirds are this can cause a crash there should not be a delay when trying to speed up”

“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.”

“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.”
