2023 Toyota Tundra fuel system problems

Filed Sep 23, 2026 · Fuel system · OH

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 service messages.Since then the truck has not been driveable,As we have specifically looked up recalls,thusly Nov.recall matched lights on the dash for the specific make,year, model of truck. From my understanding, it says that there is no remedy for such recall. But that is untrue. The remedy is an entirely new engine. They just haven't rolled out the recall info to everyone applicable. I am unable to work. My home is without a vehicle and this is unacceptable.Along w/ safety risk to me and infant. I'm sure Toyota doesn't want to admit or remedy Because that is very costly. But this was a mistake made by the company. And it should be remedied, because our family is suffering in various ways. Lost revenue. Inability to respond if emergency etc.I need a new engine.& in the interim,I need a car supplied while fixed.

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.

Add a stoplight or stop sign at a full and complete stop…. I pressed down the accelerator and nothing happens for about a second and a half… When it finally does respond, it jumps as if it was struggling to get into gear and popped itself… However, then it goes right back to normal.. But the slow starting happens very often. Definite lag when punching on the gas.

Unknown. Intermittently when merging into highway traffic from the onramp, the truck will stall and I will lose acceleration. There will be a loss in power and the truck speed will not change. instead it will just coast with no ability to change speed. I have owned the truck for 1 year and 3months. I advised the dealer and they can not duplicate the issue.

There have been multiple times, since owning the vehicle, when there is dangerous throttle lag. I step on the gas to turn and nothing happens for a few seconds. It can be pretty scary when there is a car coming and the truck just rolls for a few minutes before accelerating. It’s become a major safety concern for my family.

1-2 second period of no throttle response from a rolling stop, then a sudden lurch of acceleration many times onto a now busy intersection.
