2024 Toyota Tundra FUEL/PROPULSION SYSTEM

Throttle hesitation when leaving from a stop. Completely random and occurs maybe a few times a month.

2024 Toyota Tundra is parked on an semi-inclined driveway. The fuel gauge and miles to empty resets back to full and the miles to empty at the max around 420 miles back to empty. Reported this incident when the mileage was around 300 to the dealership and nothing was done. A year forward I am still having this fuel gauge and miles reset issue. This is a safety hazard primarily due to the risk of unexpectedly running out of fuel. While the inaccurate reading itself doesn't directly damage the engine, running out of gas can lead to several problems. It's important to address a malfunctioning fuel gauge promptly.

Ran out of fuel on highway due to erroneous fuel guage. Truck when parked on an incline will show a full tank after starting even though gas tank is 3/4 full. Problem has been reported to Dealer and no follow up nor resolution has been offered. this event is dangerous and troublesome,

Gas gauge randomly reset to full tank after parking, despite being less than half full. Without me noticing, this could have caused risk of running out of fuel due to erroneous computer information about the fuel level.

The truck hesitates to accelerate when pulling away or in middle of intersection of street, even when putting gas pedal to the floor… there is no acceleration.

The fuel gauge will randomly move to full and stay there even if the tank was almost empty. You can be at half tank and then next day it shows full and it won’t reset on its own. If you don’t catch it you will think tanks full. This could easily strand someone who assumes they have a full tank. This occurs when vehicle is parked and off on restart it shows full.

Holiday trip from Alabama to New York on [XXX] the fuel gauges (2 warning systems) malfunctioned. Since new the fuel gauge always read 415-420 “Miles to empty” after fueling, no wait. In the trip at one point after fueling the gauge started showing 24 miles until empty on a full take. This was after driving and stopping for lunch or snacks somewhere along the way. Not knowing which gauge was correct made us stop more frequently for fuel. After this event the “Miles to Empty” has never went back to the original 415-422. The miles to empty has been sporadic from 24, 100+, 200+, 300+ And last night 370. I filed a complaint with Toyota and was given a case number. The dealer says “they’ve never heard of it”. There are reports of this problem starting in 2022 and up models all over the internet but the dealer says “you can’t trust people on the www”. Actually I do trust most of the Toyota Tundra users that are reporting these problems. This problem could cause drivers/ families to be stranded for various fuel reasons. As stated for my 1100 mile trip to and from NY it made me stop more frequently for fuel so I wouldn’t chance being stranded with my family of 4. I shared a video and photo with Toyota when I opened the case. Now I am driving around helping them to figure out the problem since they refused to provide me a loaner car so they could research the problem. At the time of the initial event the gauge stayed at 24 miles to empty until I stopped for fuel. After getting the next tank the reading was sporadic until at some point going to the 300’s reading but has never returned to the 415-422 reading that it had been for the full year prior.

Repeated resetting of fuel gauge to full without filling the gas tank. Have reported this problem and dealer tried to remedy but apparently not fixed. Truck filled on 9/18/24 and everything normal. Fuel gauge and miles to empty reset on 9/24/24 after having driven 59.5 miles. MPG stayed the same. Fuel gauge and miles to empty reset while truck was running after driving 25 miles since previous reset on 9/26/24. Watched the miles to empty roll on screen. Since previous dealer service can no longer use steering wheel button to reset the MPG. Can have a false sense of available fuel and cause potential accident if truck runs out of fuel on highway or get stranded somewhere.

I previously owned a 2022 Toyota Tundra that had the same fuel gauge malfunction. It was repurchased under the Texas Lemon Law since Toyota was unable to provide a repair after a year and a half. Now I have a 2024 Toyota Tundra with the same malfunction. The fuel gauge on the dashboard will reset to 3/4s to full tank of gas after starting and stay that way until you refuel the truck even though the tank may only have 1/2 tank or close to empty. With each restart of the engine, the fuel gauge still reads 3/4 to full tank. Toyota has been unable to fix this malfunction since the 2022 Tundra model year, 3 years now! SAFETY HAZARD: I do not know how much fuel is in the vehicle. Its like putting a piece of tape over your fuel gauge and driving around and guessing when to fill the vehicle with gas. Right now I track my fuel by resetting my odometer each time at the gas station and refilling at 400 miles. Towing would be a whole new guessing game. DANGEROUS ACCIDENT POTENTIAL: Imagine being on the highway and going about 65-70 mph and the truck run out of gas and shutdown. You are now driving a powerless vehicle that may or may not have steering and trying to cross over lanes on the highway to get to the shoulder if available. Not sure at night time if the outside lights on the truck would also turn off? Toyota put out a TSB for the 2022-2023 models and it did not fix the malfunction. Now the 2024 Tundras have the same problem and there is no fix for Toyota dealers to even try on the vehicle. We are just being told, no fix at this time---3 years! ATTACHED PHOTO: I have attached a photo of the fuel gauge after I started the truck. DTE is 387, Trip A: 316, Fuel level 3/4s TRUCK ACTUALLY HAD: DTE of 205, Trip A: 316, Fuel level 3/8s Appreciate the safety concern before a Tundra owner has a serious accident.

Fuel gauge reset to full when I know there is only 3/4 of a tank of fuel in the truck.I will be taking it to the dealer today.

The fuel gauge as well as DTE resets to full when vehicle is parked nose up on slight incline. My driveway is a few degrees pitched and I park so that the nose is pointing slightly up. After going through 40-70 miles on a new full tank of fuel my fuel gauge reset to full 3 times 3 days in a row. Each time I did the trick to get the fuel sensor to reset/re-read everything while on flat ground. Video was sent to local dealer showing that the fuel gauge is resetting to full incorrectly. Toyota tried a software fix on 2022's only that did not fix the issue. They have not tried to fix it since the 2022's came out. 100's of examples of this can be found all over online. If you park on a steeper incline the tank can reset to full even if you had 1/2 or 3/4's of a tank left. This is dangerous as you could run out of fuel while driving down the highway. Its especially dangerous if your significant other borrows the vehicle and assumes the truck has a full tank of gas when it may have much less.. To my knowledge the fuel gauge and DTE will not correct itself on its own either (has not for me at least). The only way to correct it is to actually fill up with fuel again or do the workaround while on flat ground. This is a safety issue so it is surprising Toyota hasn't fixed it especially since the Tundra has been out for a few years now.

Fuel gauge is showing full when the tank is half empty according to odometer. When the vehicle is parked even on a slight incline the fuel gauge resets to full no matter how empty the tank is. This is a known problem with these vehicle and I am worried about it running out of gas at high speeds. Thank you!

The problem is faulty fuel gauge reading. My vehicle was reading between 1/2 and 3/4 on the fuel gauge. I forward parked on a driveway with at least a 30 degree incline and shut the truck off. When I returned to the truck and started it, it showed FULL. I drove it about 10 miles and shut the truck off for at least 5 minutes. When I turned it back on it still read FULL.

Fuel gauge reads full , when really there's a half to 3/4 of a tank. Will be contacting dealer and Toyota customer service.

Reported fuel gauge problem previously in electrical category. Fuel gauge will reset itself to full without filling the gas tank. This has happened on 3 occasions with only 1000 miles on the vehicle. Have been to the dealership on several occasions with no permanent solution so far. First attempt at fix was to reprogram the combination meter and the gauge did accurately show the full level. However the problem reoccurred and brought vehicle back to dealer for 3rd trip and left it for 3 days. Dealer replicated the problem but corporate Toyota said it was due to the position of the sending unit in the tank. Can possibly cause serious problems if I run of of fuel on the highway or local road. Will have to monitor the fuel until Toyota comes up with a fix hopefully.
