2023 Toyota Tundra fuel/propulsion system problems

“Vehicle: 2023 Toyota Tundra TRD Pro Hybrid, VIN [XXX], approximately 40,000 miles. The electronic fuel door release failed due to a corroded fuel door sensor/connector (diagnosed by Premier Toyota, XXX). When the fuel door system does not engage, the tank's refueling valve does not open. As a result, gasoline spits back out of the filler neck during refueling, spilling fuel onto the vehicle and the ground. This creates a fire hazard at fuel stations. Many other owners of 2022-2024 Tundra Hybrid trucks report the identical failure. I believe this is a manufacturing defect in a sealed electrical component that creates a fuel-spill safety risk.”

“Ive been waiting for years for the previous recalls I have been informed about to get fixed. Feul system,brake lights.Was told by Toyota that someone would call me to come to get them taken care of. In the meantime, constantly checking that my brake lights are working before departing on any excursions in truck & patiently waiting for toyota to reach out when they were gonna fix the first 2 recalls that I was notified about. I can't recall the date exactly, but I was driving on the highway w/ my still backward carseat, facing 2y.o. baby safely strapped in,ThankGod.As accelerating into my lane, heard huge BOOM like an IED. Immediately, the check engine light among others came on.Truck immediately lost power & was violently shaking.Felt it in the steering wheel, but largely in engine compartment.@this time,I tried to get over to shoulder to a safe place.I turned the car off.Let it rest checked on my infant in back made sure he was ok. After letting car rest, turn back on to my surprise All lights were off.I was w/in few miles of home so went directly back, never getting to my intended destination. Shortly before driveway, all lights came back on & multiple…”

“Throttle response is unpredictable. From a stop sign, acceleration is difficult to predict. Sometimes a one second delay occures before acceleration power is effected. With the time delay the throttle has been pressed further than normal. In heavy traffic, a collision could be possible. The problem got worse after a firmware update, during a safety recall to replace rearview touch screen. Pedal Lag problem is noted on Toyota Tundra forum.”

“The vehicle experiences hesitation when starting to move from a stop. So if i come to a stop and pull out into traffic it sometimes hesitates before applying the throttle that has been input via the pedal. This could cause serious injury because its almost impossible to determine when its safe to pull out into traffic because you do not know how long it will take for throttle to kick in.”
