2025 Toyota Tundra 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.”

“Vehicle Information: 2025 Toyota Tundra CrewMax 1794 Edition 4x4 (i-FORCE MAX Hybrid) VIN: [XXX] Component: Power Train / Automatic Transmission / Hybrid Propulsion System Description of Defect: I have discovered an active fluid leak originating from the transmission/bell housing area on my vehicle. There are currently no dashboard warning lights illuminated, and the transmission is not yet slipping or shifting roughly. However, the vehicle is actively dripping fluid onto the ground and undercarriage components from the powertrain assembly. Safety Risk: A transmission fluid leak on a high-pressure 10-speed automatic transmission presents an immediate safety hazard. If the transmission fluid level drops too low while driving at highway speeds, it can cause sudden power loss, transmission lock-up, or catastrophic mechanical failure, increasing the risk of a crash. Furthermore, transmission fluid leaking onto hot exhaust or hybrid electrical components poses a severe vehicle fire risk.”

“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.”

“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”

“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”

“When using the cruise control and lane keeping system the truck will jerk into oncoming traffic and try to swerve off to turning lanes. I took it to Toyota and they couldn't find any problem. no warning lights or any indication of a problem shows on the dash. At this point the system is unusable. I have seen many post of similar incidents on the internet.”
