at low speed the ADCC. FWRD Collison sensor was triggered and the brakes applied which cause the engine and engine powertrain along with the brakes to lose power and did not function as it was designed. The system was to slow and not enough power in engine to compensate for the TSS to activate and lost control temporary, and the object it was trying to avoid the collision with was a parked vehicle. My engines OIL PRESSURE gage at a low speed will at times go past 3/4- 4/4 (80-95%) and normal operation is 1/2 (50%) . I was driving on highway 90 headed east to work at 730am and while in the fast lane my truck SPLUTTERD and lost power and engine light and dash reading said POWER LOSE and my speed dropped to 55 estimate and would not throttle up. for a few seconds the brakes and engine sounded as it was shutting down and I was able to mange the truck to the slower lanes and made it to work at slow speed. The truck when sits for day at a time and when I decide to use it and start it up the truck SPLUTTERS and shakes for a brief moment until warms up. I have a huge gas efficiency problem and MPG use to read in the mid to high 20 now it reads mid 10 to 18 area. the truck is not meeting its efficiency as stated when purchased. the car hesitates and splutters if the throttle is used and the delay boggles the truck engine performance which can lead to loss of steering. The dealership says it was the airflow sensor yet they never changed it or replaced it and i now know that sense mile 6 of purchase the engine has been failing and Toyota refuses to fix or correct the engine issue or give false or misleading details and information and will not correct issues. TBE claim details and facts and images are ignored and denied by TBE. I can submit images of the dash and speed. As well as the Oil pressure gages which are obvious signs of the engine recall issues.

Since about 5,000 miles I reported abnormal tire wear, alignment, harsh or delayed shifting, and braking problems to the dealer. Repair orders from January 2024 to December 2025 show about 7 dealer visits: rear brake work three times including a rear pad replacement around 22,000 miles and an earlier rotor replacement, two drivetrain/shifting visits (first was could not duplicate) plus recall 24TA02, a check engine light diagnosis, and moisture corrosion in the reverse lamps that disabled the backup lamps and camera. The dealer denied the reverse lamp repair as commercial use and I paid 957.37 in January 2025; Toyota later issued recall 25TA06 for the same water intrusion. My truck is also covered by engine stall recall 25TA14 (the federal safety agency 26V320), but the dealer reported the remedy was not available in December 2025. Losing the backup camera and lamps and an engine that may stall are safety risks, especially when towing and reversing a boat trailer.

I was driving when the car suddenly lost power and speed. The accelerator stopped working properly. Immediately, the check engine light came on for the first time on the instrument panel, along with the "Stop Parking" alert. I immediately called for a tow truck to take me to the nearest Toyota dealership.Toyota employees informed me that the transmission is damaged and needs to be replaced. I acknowledge that my 2024 Toyota Tundra has 100,000 miles.and that the factory warranty only covers up to 60,000 miles.But for such an expensive truck, it’s impossible for the transmissions to have a lifespan of only 100,000 miles.

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 (the federal safety agency 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 my 2024 Toyota Tundra, the check engine light illuminated and the vehicle suddenly experienced reduced engine power. I safely pulled over, shut the engine off, and restarted it. After restarting, the vehicle appeared to operate normally, but a diagnostic scan showed DTC P0300 (Random/Multiple Cylinder Misfire). On July 20, 2026, I brought the vehicle to an authorized Toyota dealer for inspection. During the inspection, the dealer found significant metal shavings in the engine oil, indicating a possible internal engine failure. Based on these findings, the dealer instructed me not to drive the vehicle and retained it at the dealership because they considered it unsafe to operate. My vehicle is already included in Toyota’s engine recall related to engine manufacturing defects. However, despite the dealer confirming the presence of significant metal shavings and advising that the vehicle should not be driven, no repair or resolution has been provided. The dealer has been unable to provide an estimated repair timeline or when the vehicle will be returned to service. The vehicle is available for inspection. No crash or injuries occurred. Prior to the incident, there were no warning signs or abnormal symptoms. The check engine light and reduced engine power occurred suddenly while driving. The unexpected loss of engine power created a significant safety risk, particularly while driving at highway speeds or in traffic. I am also concerned that an apparent internal engine failure occurred with little or no warning. In addition, because the dealer has retained the vehicle and no rental or alternate transportation has been provided, I have been left without transportation while waiting for a resolution.

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.
