Your Fuel Gauge On 2022 Toyota Tundra Is Not Broken. Here’s What To Do

Have you noticed that the fuel gauge on the 2022 Toyota Tundra has sometimes stated that it is full even though you may have half a tank? There is a simple fix that that dealer can do.

As more and more people see that the new 2022 Toyota Tundra is indeed a pretty good truck (if you don’t get a bad one), more and more subtle little problems start to become seen in the mainstream forums. Things like the seat trims cracking or window seals coming loose. However, the majority of Tundra owners say that they have a pretty good truck. Remember, any problem for Toyota is not going to be a small problem. If 1% of trucks are affected by problem A, then that’s a lot of trucks in terms of quantity.

On Facebook’s 2022+ Toyota Tundra Owners group, Benjamin Baatz surfaced one such problem. He said, “Does anyone else’s fuel gauge show full when it’s warm outside? It went from 3/4 to full just sitting in the driveway.” Now don’t think that your truck makes its own fuel. While that would be very convenient, the 2022 Toyota Tundra does not have that capability. Instead, a lot of owners have said it is due to a calibration error which the dealer would have to fix.

Becky Haskell said, “Mine does that if I park on a slope. Tell the dealer it needs to be recalibrated.” This is a very simple fix which you could do now or when you go to get an oil change. Usually this will not affect your average mpg as that calculation is not done by the amount of gas you have in your tank or at least what the computer thinks is the amount you have. However, this could be pretty bad if you always forget how much you put in. if you filled up 2 weeks ago and it still shows that it is full, chances are you are already running low and may need some more gas.

My advice is to either keep an eye on it and remember how much gas you have or just get a quick re-calibration from the dealer. It should be covered by your warranty anyway. Small things like this are usually covered but it would be a good idea to call ahead and make sure that this is something that can be covered. However, just like almost all other Toyota vehicles, if you for some reason moded your Tundra’s fuel tank, then that warranty would be voided because they could just blame it on your mod.

Make sure to only mod things that you know are less likely to fail like wheels and tires or even a few body mods. Check out our older article on Toyota’s bumper to bumper warranty.

All in all, I think that this isn’t something to panic about however it could be catastrophic if you don’t keep an eye on it.
