Toyota Tundra transmission problems

POWER TRAIN

-Our Toyota Tundra Hybrid suffered total catastrophic engine failure due to metal shavings found throughout the engine and oil system. This is the same issue that prompted NHTSA ID Number: 25V767000 recall of Toyota's V35A engines. The tundra is available for inspection. -Statement regarding safety put at risk by my husband: I felt a vibration from the engine compartment (seeming to come from the front right side) and then I suddenly lost complete power. I was traveling in the number one lane (the fast lane). I immediately put my hazards on and had to navigate to the number two lane and then over to the narrow shoulder under no power whatsoever. I had to navigate around multiple semi-trucks. This was a very dangerous situation and I barely got it over to the shoulder. If my teenage daughters were driving this car they likely wouldn't have been able to safely navigate it across two lanes with no power in the setting of multiple semi-trucks on a two-lane divided highway. Again, a very dangerous situation. I shut down the engine and waited five minutes and restarted it. Shifting into gear the warning indicator said 'hybrid system disconnected'. -The total catastrophic engine failure has been confirmed by the Toyota Dealership. Th4ey Confirmed multiple shavings of metal in the entire oil system and the engine has seized. He said that the engine needed to be replaced. -The tundra has not been inspected by the manufacturer, police, insurance (yet) or others besides the Toyota dealership. -There were no warning lamps, messages, or other symptom of the pending catastrophic total engine failure.

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.

My wife and I purchased a brand new Tundra LTD in May 2023. An important note to keep in mind is that my wife and I not only purchased the new Tundra but also a new travel trailer so we could enjoy our nation's national parks during our retirement years. I will relate that to my complaint shortly. It wasn't long after our purchase that we became aware of the issue of machining debris possibly contaminating the engine block which can result in sudden engine failure. Right now, because Toyota has not resolved our issue and communication has generally been close to non-existent. We no longer feel we can safely take our truck and trailer to the remote national parks of the American southwest where distances are huge and help few and far between. We have visited the SW twice and want to do more while we are still young enough to do so but are worried about what a sudden breakdown would do. I called up Toyota and asked them to repurchase the Tundra so I could buy a new onw without the issue. I explained that I paid for the Truck in good faith but that they have not kept up the end of the bargain, the truck Toyota sold us is potentially unsafe and we'd like it fixed or repurchases which would allow us to buy a new truck. They closed out my official inquiry without comment or communication of any kind. Apparenty, they are just fine with consumers being sold a truck that may suddenly die on them. Anyway you folks can get Toyota to fairly take care of its customers?

As many have spoken about already, I have the hesitation or lag from stop or rolling at very slow speeds. I kind of learned to live with it but feel it's getting worse. My wife had to drive the truck, and she said it was very scary and did not feel safe. I know it is not the engine as I had it replaced and problem is still very much there! There have been so many issues with this truck. Brakes have never stopped squeaking; one dealership guy told me it is the cheap pads Toyota put on them.

While driving, the vehicle unexpectedly stalled and lost power. The vehicle was taken to an authorized dealership for diagnosis, where the same stalling condition was reproduced and confirmed during a dealer road test. The vehicle had to be towed back to the dealership, where the engine was found to be seized. The sudden loss of power while driving created a serious safety concern because the vehicle could become disabled without warning and lose motive power in traffic. The failure was confirmed by the authorized dealership, and the vehicle and engine were available for inspection during the repair process. There were no known warning lamps, diagnostic messages, or other clear advance warnings that would have allowed me to anticipate the engine failure before the vehicle stalled.

The TCM is faulty. There is a tsb so Toyota is well aware of the issue. They will not take care of it under the power train warranty. The TCM doesn't shift the vehicle correctly. This lag and funny shifting almost caused an accident.

My 2024 tundra with 55000 miles suddenly lost all power going down a major highway. The engine failed suddenly. Luckily I didn’t wreck. I paid out of pocket to have it towed to dealership where it has sat untouched for 9 days. The engine is included in the recall that they have.

Manufacturer Recall Number25TB06 NHTSA Recall Number25V322 In regards to the above mentioned recalls. The vehicle's reverse camera began flashing while driving forward. The R light on the gearshift was also flashing. While driving forward about 15 mph out of a parking lot, the vehicle suddenly went into reverse on it's own, locked up and would not move. I had to have the vehicle towed to the dealership. This happened around the week of June 8. The dealership says that they reset the electrical recall, we picked up the truck and it ran fine for about a week. The reverse camera and R light on the gearshift began flashing again on June 17. It did not shift itself into reverse, but the dealership requested that we bring the vehicle back. The dealership stated that Toyota has "grounded" the vehicle and does not have a fix for the recall to date and continuing to drive it is a safety hazzard. It has been sitting at the dealership since June 18 with no end in sight. The dealership and Toyota Corporate continues to tell me every few days that they do not have a fix for the issues/recalls.

When you almost stop but then hit the gas there is a dead petal. The vehicle doesn’t accelerate. Then you almost get t boned. They know about the problem but say everything is fine. It’s traction control. It is not. I guess I will have to sue if I survive the crash.

This is a reoccuring issue and happens daily. When the vehicle is cold and sitting all day or all night, on the first 5 minutes of driving or so, when you push the accelerator pedal from a dead stop or rolling stop, there is no throttle/engine response for at least 1.5-2 seconds. This is a HIGHLY unsafe condition and can lead to a traffic collision. I have reached out to Toyota Corporate about this and they said to bring it into my local dealer, Dick Hannah Toyota in Kelso, WA to perform the rolling stop TSB that is out on these Tundra Trucks. I received information from Dick Hannah that when they went to perform the procedures to take care of this TSB, that it had already been done and that there was nothing they could do further. They asked me to document the conditions to try and get Toyota Corporate to do something about it. I asked if there wasn't a recalibration they could do or anything else to make this condition improve, and they said no there is not. I expressed my concerns saying that there is nothing to document, that this happens everyday and is a daily occurence whenever the vehicle has been sitting for a long period of time. I have reached out to other vehicle owners on vehicle forums on the internet that are experiencing the same exact problems with no remediation from Toyota Dealers or Toyota Corporate. I was even offered to get into a split to hire a lawyer to get this unsafe condition remedied. This is a big deal and should not be overlooked and written off by ANYBODY.

I own a 2024 Toyota Tundra 1794 Edition with approximately 37,000 miles. On or about XXX, while driving, the vehicle displayed a “Check Engine” warning, “Reduced Engine Power” message, and the Pre-Collision System became disabled. The vehicle immediately became sluggish and lost power during acceleration. The loss of power created a safety concern because the truck was unable to accelerate normally when entering and crossing intersections. I did not feel safe continuing to drive the vehicle, especially while transporting my 9-year-old daughter. Due to the safety risk, I parked the vehicle and have not driven it since the warning first occurred. The warning lights remain active. The vehicle has not yet been inspected by a Toyota dealer because I do not believe it is safe to drive to the dealership. I am requesting dealer evaluation and towing assistance. The component that failed is currently unknown. The vehicle is displaying a check engine light and reduced engine power condition. The condition can be inspected and diagnosed by Toyota. No crash, injury, or property damage occurred because I immediately stopped using the vehicle once the safety concern became apparent. I am submitting this complaint because a sudden reduction in engine power while driving creates a significant traffic safety hazard.

was waiting for the traffic light to turn green. Vehicle in drive with foot on brake. the traffic light turned green, I took my foot off the brakes and pushed on the accelerator. Nothin happened. I saw another vehicle approaching at a high rate of speed behind me so I continued to mash on the accelerator. right before being hit by the car behind me my vehicle lurched forward a few feet then stopped again. I looked at the dash display and saw a "Hybrid System Malfunction" warning. Because of the traffic situation/location it was not safe to just sit in the road so I continued to pump on the accelerator. each pumped moved the vehicle forward a couple of feet. I did not turn of the engine because I was unsure what would happen so I continued to do that for about a mile or so until I could get to a safe place to pull over. during this time, I almost got rear-ended and side-swiped several times. Once stopped I attempted to start the vehicle several times and got the "Hybrid System Malfunction" display and the vehicle would not start. I waited for about an hour with the vehicle off and restarted the engine. I stayed off the freeway and took backroads to the closest dealer service center where it is currently located. When I dropped it off the service rep said he hasn't seen anything like this. Prior to this incident I had no issues with the truck and it was last serviced by the dealership on March 4, 2026.

While driving my 2024 Toyota Tundra Hybrid, the engine suffered a catastrophic seizure at approximately 37,974 miles. The dealership retrieved substantial metal machining debris (swarf) from inside the engine, which had contaminated the #1 main bearing. This is the exact same manufacturing defect Toyota has publicly acknowledged in multiple safety recalls for 2024 Tundras. Service Manager Dan Moran at Toyota of Colorado Springs confirmed during a recorded call that his dealership has seen the identical debris-related engine failure in other hybrid Tundras. Despite this, Toyota excludes all hybrids from the recalls. Even with clear physical evidence matching the recalled defect, Toyota directed an in-house rebuild (using a new short block but many of my original contaminated components) instead of providing a full factory crate engine. I was never offered a choice in the remedy. This sudden engine failure created a serious safety hazard due to unexpected loss of power. The current repair does not fully eliminate the known root cause (manufacturing debris contamination). The vehicle was well within warranty at failure and remains so. The dealership has the debris and full repair records available for inspection. I have also submitted the debris photo, repair documents, and recorded call summaries to NCDS (Case #[XXX]) and the Colorado Attorney General’s office.

From date of purchase… when truck accelerates from dead stop, drive train shudders for several seconds before fully engaged. Suspect issue related to software, hybrid enterface with drivetrain, torque converter not locking up. Dealer verified condition with test drive. Concluded it was operating normally. I don’t buy this explanation. Is it going to fail me entering traffic? Will it get progressively worse?

While traveling on US Highway 95 between Lewiston and Riggins, Idaho, a 2024 Toyota Tundra TRD Pro with approximately 18,000 miles experienced a sudden loss of engine power while descending a mountain grade with multiple curves. The driver reported hearing abnormal engine noises immediately before the loss of power. At the same time, the brake pedal became extremely hard to depress and the vehicle did not decelerate as expected, requiring substantially increased braking effort. The vehicle was carrying family members and was traveling on a winding downhill section of highway adjacent to steep terrain. Due to the loss of power and increased braking effort, the occupants feared the vehicle would be unable to stop safely. Fortunately, a roadside pullout area was available, and the driver was able to steer the vehicle into the pullout and bring it to a stop without a collision. The vehicle was towed to an authorized Toyota dealership for inspection. The dealership diagnosed the vehicle with a catastrophic engine failure requiring engine replacement. The failed engine remains in the possession of the dealership and should be available for inspection. Approximately five days before this incident, the vehicle had undergone routine maintenance, including an oil change and inspection at a Toyota dealership. The vehicle had also previously been presented for brake pulsation concerns and other drivability-related complaints. The vehicle was returned to service and represented as operating normally. No collision occurred and no physical injuries were reported; however, the incident created a significant safety risk because the loss of engine power occurred while descending a mountain highway and the driver experienced substantially increased braking effort while attempting to stop the vehicle.
