2024 Toyota Tundra

On XXX6, while driving on the highway at approximately 89 mph and 36,714 miles, the engine misfired and the vehicle began shaking. The check engine light started flashing and a "reduced power, visit dealer" message appeared, along with a loss of motive power. The vehicle was taken to an authorized dealer on XXX at 37,032 miles. The dealer's repair order documents stored diagnostic trouble codes for random misfires, and states that freeze frame data confirmed misfires on cylinders 3, 4 and 5 at 89 mph and 2700 rpm in direct injection mode. Despite this, the repair order was closed as "no issue found." No repair and no further diagnosis was performed. The dealer stated the condition could not be duplicated after driving the vehicle and idling it for about an hour. The vehicle is subject to an open safety recall for machining debris in the engine (NHTSA 25V767, manufacturer 25TB14), for which no remedy is available. The recall summary lists engine knocking, rough running, no-start and loss of motive power as symptoms, and instructs owners experiencing symptoms to contact their dealer. When contacted, the dealer stated the manufacturer is still developing a remedy and that the vehicle can either wait indefinitely or be picked up as is. The defect remains undiagnosed and unrepaired. The vehicle is available for inspection. The safety concern is a sudden loss of motive power at highway speed, which is the same risk identified in the manufacturer's own recall filing. No remedy has been made available more than ten months after the recall was filed.

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.

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.

The contact owns a 2024 Toyota Tundra. The contact received notification letters for NHTSA Campaign Numbers: 25V322000 (Exterior Lighting) and 25V767000 (Engine and Engine Cooling); however, the parts required to complete the recall repairs were not yet available. Additionally, the contact stated that while reversing, an abnormal popping sound emanated from the differential. No warning lights were illuminated. A local dealer was contacted, but the vehicle was not diagnosed or repaired; however, the dealer sent an email offering a vehicle buyback. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 4,300.

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.

The contact owns a 2024 Toyota Tundra. The contact stated that on two occasions while driving at undisclosed speeds, the vehicle lost motive power while attempting to accelerate from a complete stop. Upon depressing the accelerator pedal, the vehicle abruptly stopped in the middle of an intersection, with the brake warning light illuminated. The vehicle resumed normal operation after several seconds. The vehicle has not yet been diagnosed or repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 12,000.

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.
