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.

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.

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.

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.

Recall 25V‑767 (Toyota 25TB14) is open on my VIN with no remedy available. Full statement and sources attached. XXX 12 days after the recall was filed and before I had any notice, my check engine light was on at an oil change at Colonial Toyota, [XXX]. The tech showed me the dealer's video of it and the light was cleared. I reported rough running and hesitation pulling away, and fear of a stall in traffic. The only rental offered was a subcompact, which cannot replace my full-size truck or tow my trailer. I was told nothing could be done until Toyota released a fix. None of this is on the repair order. I stopped driving the truck; by mid-XXX it had 19,923 miles. I asked the dealer in writing on XXX for the video, the cleared-code record and their retention policy. No response. Toyota says the video was auto-deleted and that it found no codes, but produced no code report and no deletion record. Toyota met the federal safety agency about rising failures XXX my CT lemon law protection ended XXX; the recall was filed XXX. The first recall (24V‑381) replaced engines; this one uses inspection software, and is still not available for my truck. Six owners sued over this engine ([XXX] v. Toyota Motor North America, D. Vt. No.XXX. In XXX Toyota paid the federal safety agency $48.8 million in penalties, including for late defect reporting. Please review whether: the remedy is timely and adequate; dealers are clearing codes without recording them, keeping warnings out of recall data; owners get usable transportation; and Toyota reported this defect as promptly as required. I am also preparing a formal complaint to the United States Department of Justice. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The fuel pump and the fuel pump control module system failed. Before the failure, I drove my 2019 Toyota Tundra on XXX from [XXX] to [XXX] with no prior check engine light warning. It was parked for all 3 days at a campground in [XXX]. However, on XXX the vehicle would not start. The truck ignition was moved to the RUN position and then the check engine light came on, which was the first notification of a potential problem. So, I attempted to start the vehicle, there was a crank but not a start incident. The ignition was moved back to the OFF position. I'm also an experienced mechanic, so I lifted the hood to diagnose the issue and search where the malfunction was occurring. I inspected the battery, all the fuses, the relays controlling the fuel pump, and the fuel pump control module. Using a Voltmeter Tester, the battery had a full charge. The relays and the fuses were also replaced with no success in starting the vehicle. The fuel line was disconnected from the fuel rail so I could verify if fuel was getting to the engine. The truck ignition was again moved to the RUN position and then the Start Position with NO success of fuel getting to the fuel rail. The vehicle was then towed to a local auto shop and the problem has been reproduced only by Crawford Auto Repair shop in [XXX]. The auto mechanic mentioned two error codes were presented: 1. The fuel pump 2. The fuel pump control module. Thankfully, there was no immediate risk to my family's safety but it could have occurred while driving back through the [XXX] mountains on our way home.

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.
