Lemberg Law is investigating an increasing volume of complaints that the third generation 2022-2024 Toyota Tundra has a major fuel gauge issue. Owners are complaining that the truck resets the fuel gauge to full when it isn’t. Others say that the gauge doesn’t reflect that the tank is full after they’ve refueled. Either way, they can’t tell how much fuel they’ve got available, which is a real problem, especially on longer trips.
Are There Fuel Gauge Problems with the 2022-2024 Toyota Tundra?
Fuel gauge problems are common for all model years of the third-generation Toyota Tundra — 2022, 2023, and 2024. There are official complaints about the issue to the National Highway Traffic Safety Administration (NHTSA) as well as lengthy threads in the Tundras forum and on Reddit.
Toyota has acknowledged that there is a problem with some 2022 model year Tundra and Tundra Hybrid vehicles. But they haven’t shown any recognition that it’s a problem for the later model years. Also, the stories owners are sharing about their 2022 model issues show a plethora of other elements and issues.

What Does Toyota Say About Faulty Tundra Fuel Gauges?
Technical service bulletin T-SB-0022-23 is one of 80 manufacturer communications issued to dealerships that are listed on the NHTSA website. Regarded in the records as an electrical system issue, it is dated May 12, 2023 and lists two problems:
- Fuel gauge readings may increase when vehicles are parked on an incline. This is because the front of the vehicle rises higher than the rear of the truck.
- The oil pressure gauge reads a little below a quarter when the vehicle is cruising at a constant speed or when the engine is idling.
Toyota has modified the combination ECU logic to reduce the chance of these issues occurring. The TSB describes the process dealerships need to take to address these conditions.
What Fuel Gauge Problems are Toyota Tundra Owners Experiencing
The oil pressure gauge problem isn’t something that Tundra owners are highlighting. It’s the fuel gauge readings that concern them.
Examples of Fuel Gauge Complaints on NHTSA
An owner from Wisconsin complained about a faulty fuel gauge in his 2022 Toyota Tundra in July 2023. “My gas gauge does not work properly.” While it shows the gauge is full after filling the tank, after traveling 40-70 miles, it registers as being ¾ full. “Then I turn it off and when I turn it back (on), the gauge goes back to full.”
A quick online search shows that owners of 2022 Tundras who don’t have fuel gauge problems say they get anything from 336-420 miles on a full tank. So, a quarter tank should take owners at very least between 84 and 105 miles — not 40 to 70 miles.
This owner went back to the dealership twice. The first time, they replaced the gas pump “and some other things.” That didn’t work and the problem recurred. The second time, “they told me Toyota has no solution to fix my gauge.”
An owner of a 2023 model from Nevada tells a slightly different story. Having fueled the Tundra and started the truck, “I started my car (and) my fuel gauge remained the same, as if I never put full. I turned off my vehicle and started it again. The fuel level still did not change.” So, he went to another pump to see if there was fuel in the tank. It indicated it was full!
“I drove around for 15 minutes but (there was) no change to the fuel gauge. I parked the vehicle at home and planned to take it into the dealership the following day, but my fuel gauge corrected itself later displaying a full tank.”
One complaint mentions the effect of an incline, stating that the tank read it was full after two hours, when it was previously at ¾ of a tank.
An early post in Tundras.com states more or less what the TSB for the 2022 model tells dealers about. In July 2022, when an owner had parked on an incline, the fuel gauge went from ¾ to full. Another states that after traveling 182 miles on the first tank of gas, after parking on a hill, the tank registered full.
Some who have had the TSB procedure performed on their trucks say it doesn’t work.
Some say that after parking on level ground, the tank sorts itself out. Other owners say that the level of the ground isn’t an issue.
And then there are those who say that the TSB doesn’t work. A month after the TSB “fix” was performed in mid-2023, an owner found that after parking on a driveway with an incline, he “suddenly had a full tank of gas again!”
One of the most recent comments is from the owner of a brand new 2024 Toyota Tundra Limited. “Was hoping they had this fixed before I took possession Monday. Will try the work-arounds when I get home tonight.” In October 2023, he had parked nose-up with ¾ of a tank of fuel, but it registered that it was full. It seemed to rectify the reading when parked on a level surface later.
But does it really relate to so-called level parking?
“I’m not convinced that ‘level parking’ is the whole story here. Mine reset from ½ a tank to full after being parked on completely level ground and never reset itself. It remained inaccurate for ~200 miles until I filled up with fuel based on my trip odometer. I always reset after fueling.”
Does Toyota Know About Fuel Gauge Issues?
We know that Toyota issued a TSB in May 2023 that was designed to deal with the problem 2022 Toyota Tundra owners were having. We also know that the TSB doesn’t acknowledge the whole problem. But according to comments on Reddit, in May 2023, dealers were claiming this was the first they had heard about the problem.
“Brought my truck to the dealership this week. They forwarded the issue up to the technicians at Toyota and started a case. Apparently this is the first Toyota is hearing of this. When enough people go in with this issue they will eventually get a fix in progress.”
Maybe they do, maybe they don’t, but after years of customers complaining, what do you think?
There is a record of an offer of a buyback from Toyota. In August 2023, a member of the Toundras.com forum posted: “Toyota called me today about it and said they may start offering to buy back the truck. And if you decline the buyback any further issues will not be fixed. Which kinda sucks cause if I buy another one the rates are much higher now.”
