Filed Nov 6, 2026 · Brakes, Driver assistance · TX

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.

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.

2023 Toyota Tundra. On July 20, 2026 and again on September 18, 2026, while driving, the truck suddenly lost power and went into limp mode. The dash showed 'Check Engine / Reduced Engine Power / Visit Your Dealer' at about 43,440 miles. The truck had to be towed to the dealer on a flatbed. Losing power without warning in traffic is a serious safety risk. Other ongoing problems: the brakes squeaked for over a year before they were fixed, the driver seat bolster plastic is broken (this would be the third repair), the radio volume knob has failed, and there is excessive wind noise. This VIN still shows open recall 25V767 (engine machining debris causing loss of motive power), which has not been performed despite two dealer visits for this exact failure.

On Saturday, XXX, while driving on [XXX] toward [XXX], our 2024 Toyota Tundra (VIN: [XXX]) lost power and stalled at highway speeds with the warning: "Ignition On / Engine Off – Stop in a safe place." I made an emergency lane change with 6 vehicles trailing closely. After smoke expelled during restart attempts, Toyota Roadside towed the truck to Goldsboro Toyota at 5:15 PM. On Monday,XXX, Goldsboro Toyota exhibited negligent, misleading treatment. A receptionist falsely claimed they "ordered a new engine" for the recall and refused to release the truck to Midlands Toyota near our home in [XXX]. Despite written instructions on the intake form, we waited 7 hours with no update. On Friday, XXX, Toyota Corporate contradicted the dealer, confirming no technical remedy or engine currently exists for active federal Safety Recall 25TA14 (the federal safety agency [XXX]). This catastrophic engine failure created an extreme safety hazard that severely triggered my wife’s diagnosed ADHD and depression (Eggshell Plaintiff Doctrine). The dealer’s refusal to release our truck also disrupted my work during a critical corporate shareholder transition. Under the federal Magnuson-Moss Warranty Act and state breach of warranty laws, we demand a Full Manufacturer Repurchase (Buyback): 1. Full payoff of our remaining loan balance to our lender. 2. Complete refund of all out-of-pocket payments: down payment, all $824 monthly payments, sales taxes, and county fees. 3. Full reimbursement for direct expenses and tax penalties. 4. Non-economic cash settlement for severe hardship, safety risks, and aggravated emotional distress. 5. 100% coverage of all statutory attorney’s fees as required by law.

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.

When driving on the freeway at 70mph speeds during rush hour, I lost all power to the vehicle causing me to have to immediately pull to the side of the freeway with minimal control of the vehicle. I had to come to a complete stop on the freeway putting myself and others at high risk for a high speed crash. There were no warning lamps just a full system failure. There are recalls on certain VIN numbers for the Denso Low Pressure Fuel Pump and a class action lawsuit settlement that resulted in Customer Support Program 23TE05 but when I called Toyota they said my VIN did not qualify.

My 2026 Toyota Tundra TRD Pro developed a sudden, loud knocking noise from the engine at approximately 15,000 miles while I was driving. The engine began running very rough, the vehicle started shaking, and the engine was losing power as I pulled over. The knocking was most noticeable at low RPM and followed engine RPM. There were no warning lights or warning messages before the problem occurred. I was able to safely pull the vehicle off the road, but the sudden loss of engine power and severe shaking created a safety concern. If the failure had occurred in heavier traffic or at highway speed, the loss of propulsion could have created a significant risk to me, my passengers, and other motorists. I stopped driving the vehicle because I was concerned about a complete engine failure. The vehicle was taken to an authorized Toyota dealership and is currently available for inspection. The dealer has confirmed the abnormal engine noise, but as of the date of this complaint the engine has not yet been disassembled and the exact internal cause of the failure is UNKNOWN. The vehicle has approximately 15,000 miles and is covered by the manufacturer's warranty. I am filing this complaint because the engine problem occurred suddenly at very low mileage and resulted in severe shaking and loss of engine power while driving. I am concerned that this condition could result in a complete loss of propulsion. I will provide additional information when Toyota completes its diagnosis.

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.
