RAV4 Hybrid gas tank won't fill all the way: which ones have the problem, Toyota's free fix, and what's normal

So the question most RAV4 Hybrid owners ask is some version of "the pump clicks off at 9 gallons, so is my tank broken?" And used buyers ask whether the RAV4 Hybrid they're looking at was fixed, and whether the gas tank problem even matters. So in this guide I'll go through which RAV4 Hybrids have the gas tank problem, what's normal and what isn't, and how to get Toyota's free fix. I'll also cover how to check a VIN and a repair order, what happened with the lawsuit, and which filling tricks are safe.

Quick picks

Which RAV4 Hybrids have the gas tank problem

So the gas tank problem is on RAV4 Hybrids built from mid-August 2018 to mid-November 2020. That covers most 2019 and 2020 RAV4 Hybrids and the first 2021 RAV4 Hybrids. Toyota split the free fix into three programs, because cars built at different times came from the factory with different parts.

Basically, the fuel sender is the part inside the gas tank that measures how much fuel is left and sends that reading to the gas gauge. And the build dates in the table overlap because Toyota sorts the cars by factory and VIN, not just by build date. So the dealer looks up your exact VIN in Toyota's repair bulletin, called T-SB-0109-20, to see which fix your RAV4 Hybrid needs.

Something to note is that all three programs are for the RAV4 Hybrid only. The 2019 to 2025 gas RAV4 isn't in any of them, and owners don't report the gas RAV4 having the same problem.

What's actually wrong with the 2019 to 2021 RAV4 Hybrid's gas tank

So Toyota blames two things. The shape of the gas tank varies a little from car to car, and the fuel sender inside the tank can end up tilted. Toyota says those two things can make the car read the fuel level wrong, and turn on the low-fuel light with more gas in the tank than usual.

And these are the three signs Toyota lists in its letters to owners:

• The gas gauge needle doesn't reach F after the pump clicks off.
• Less gas goes in than you'd expect.
• Distance to Empty, the miles-left number on the dash, reads lower than you'd expect.

Now owners and a Toyota salesman on YouTube describe the RAV4 Hybrid's gas tank as a saddle shape that wraps around the rear drive parts. But Toyota itself only says "tank shape," so the saddle shape is a reported explanation, not something Toyota has stated.

And keep in mind that the gas tank problem doesn't change your mpg. Toyota says the problem won't raise or lower fuel economy. Basically, you just go fewer miles between fill-ups.

Is 10 or 11 gallons after the low-fuel light normal on a RAV4 Hybrid?

So yes, 10 or 11 gallons after the low-fuel light is normal, and this is the part most people get wrong. A healthy RAV4 Hybrid never takes 14.5 gallons at the pump.

Basically, two things keep a RAV4 Hybrid from taking the full 14.5 gallons. First, the low-fuel light comes on with about 2.2 gallons or less still in the tank on a 2019 to 2025 RAV4 Hybrid, according to Toyota's owner's manual. On the 2026 RAV4 Hybrid, the light comes on at about 2.5 gallons. Next, the pump clicks off before the tank is completely full. Toyota says the fuel system is built that way so gas doesn't splash back out after the nozzle stops. Toyota also says the temperature and the pump nozzle at each gas station change how many gallons go in.

So here's Toyota's own test, from the program letters it mailed to owners. Wait for the low-fuel light, then fill until the nozzle clicks off the first time, and read the pump.

And here's what that means for how far you go between fill-ups. At 38 mpg, 9.5 gallons after the light gets you about 360 miles. And 10.5 gallons gets you about 400 miles. The 580-mile number people quote is 14.5 gallons times 40 mpg, and no RAV4 Hybrid gets that between pump stops. Basically, there's always some gas left in the tank when you fill, and some room left at the top when the pump clicks off.

Now here's what a problem RAV4 Hybrid looks like in real life. Owners of 2019 to 2021 RAV4 Hybrids filed about 280 complaints with NHTSA, the National Highway Traffic Safety Administration. Of the owners who gave a number, the middle number was 9.5 gallons, and half of them got between 9 and 10 gallons. Most of them were filling from the low-fuel light or from empty.

How to get Toyota's free fix under 20TE04, 20TE05 or 20TE06

So the three programs are what Toyota calls Customer Support Programs. Basically, a Customer Support Program is Toyota fixing a known problem for free, even though it isn't a safety recall. Here's what the three programs cover:

• How long the coverage lasts: The coverage lasts 8 years from when the RAV4 Hybrid was first sold, or 100,000 miles, whichever comes first. It's the same for 20TE04, 20TE05 and 20TE06.
• Later owners: The coverage stays with the car, so a second or third owner gets the same free fix.
• When Toyota does the fix: Toyota only does the fix when the dealer's test confirms the problem. Toyota's letter says that if your RAV4 Hybrid isn't showing the problem, you don't need the repair.
• Rebuilt and salvage titles: Toyota counts the programs as emissions related, so RAV4 Hybrids with salvage, total loss or similar titles still qualify.
• Where to go: Any Toyota dealer can do the program work, and only a Toyota dealer can.

And here's how to get the fix done:

1. Call the service department at any Toyota dealer. Tell the service advisor you want an inspection under the 20TE04 fuel tank program, and give them your VIN. The VIN, or vehicle identification number, is the 17-character number on your registration and at the bottom of the windshield on the driver's side. If your car falls under 20TE05 or 20TE06 instead, the dealer will see that from the VIN.
2. Fill the gas tank right before the appointment, until the nozzle clicks off the first time. Toyota requires the tank to be filled to the click before the dealer inspects it. Don't top off.
3. Expect the inspection to take about an hour. If the RAV4 Hybrid fails the test, the repair takes about another hour, according to Toyota's letter. Toyota gives dealers 2.1 to 3.0 hours of labor for the repair, so plan for the dealer to keep the car a while.
4. Ask for a copy of the repair order when you pick the car up. The repair order shows a labor code that tells you whether parts were replaced, and I explain how to read those codes in the VIN section below.

Now if your RAV4 Hybrid got a new gas tank before November 2020, that wasn't the program fix. Before the program repair started in late October 2020, Toyota let dealers put in a replacement tank of the old design. And Toyota told dealers at the time that the replacement tank might not stop the problem from coming back. So if a RAV4 Hybrid with one of those early tanks still takes under 9.8 gallons after the light, I'd take that RAV4 Hybrid back to a Toyota dealer under 20TE04.

When Toyota's free fix runs out, by model year

So Toyota doesn't publish an end date, because the 8 years start on the day each car was first sold. The dates below are worked out from when each model year went on sale. And any RAV4 Hybrid past 100,000 miles is already out of coverage, whatever its age.

And in Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont and Washington, the gas tank also falls under the California emissions warranty. That warranty is 7 years or 70,000 miles. But Toyota's program lasts longer, so the emissions warranty rarely matters for the tank now.

What the gas tank costs if you're past the coverage

So if your RAV4 Hybrid is past 8 years or 100,000 miles, you'd be paying for the repair yourself. A genuine Toyota gas tank, part number 77001-0R101 at Toyota Parts Deal, was $558.10 with a list price of $833.32 (checked October 15, 2026). Keep in mind that Toyota Parts Deal's fitment list for 77001-0R101 includes some gas RAV4s too, so confirm the part with your VIN before you order. Toyota allows 2.0 hours of labor for a gas tank swap on a 2023 RAV4 Hybrid. And one 2023 RAV4 Hybrid owner was quoted $1,788.85 to remove, inspect and replace the tank.

What owners get after Toyota's fix

So the honest answer is that Toyota's fix gets most RAV4 Hybrids to about 11 to 12 gallons after the low-fuel light, not 14. At 38 mpg, that's about 420 to 450 miles between fill-ups. Here's what owners reported after the program repair:

• A 2020 RAV4 Hybrid owner went from 9.3 gallons to 11.3 gallons after the low-fuel light.
• A 2019 RAV4 Hybrid owner went from 9 to 10 gallons before the fix to 11 gallons after.
• Another 2020 RAV4 Hybrid owner put in 11.8 gallons with 27 miles left on Distance to Empty.
• One 2019 RAV4 Hybrid owner says the tank still only holds 12.5 gallons in total after the fix. The dealer told that owner the space at the top is there by design, so gas doesn't splash back.
• In the lawsuit, one owner's tank took about 13 gallons when nearly empty after the fix, and another owner's took about 10.

So most of those numbers sit inside Toyota's normal range. But owners are still disappointed, because they expected to put in close to 14.5 gallons.

Now some owners say the fix only recalibrated the gas gauge. Toyota's repair bulletin and parts lists show the dealer replaces physical parts, either the gas tank, the fuel sender or both. And a new fuel sender does change what the gas gauge reads, which is likely what those owners notice.

And if a dealer tells you your RAV4 Hybrid is "within spec," ask what the scan tool read right after the click. Under 12.6 gallons in the tank means Toyota's bulletin tells the dealer to keep checking.

Why the gas gauge and Distance to Empty read the way they do

So a lot of "my gauge didn't move" reports have a simple cause. Toyota's manual says to turn the RAV4 Hybrid off before you fill up. If the car is still on while you fill, the gas gauge and Distance to Empty may not update. And the gas gauge and Distance to Empty may not update if you only add a little gas, either.

Now Distance to Empty is an estimate, not a measurement. Basically, the car works out Distance to Empty from your recent mpg, so the same full tank can show more or fewer miles depending on how you've been driving. Toyota says weather and road conditions change Distance to Empty too. So don't use Distance to Empty alone to judge whether your gas tank has the problem.

• On a 2019 to early 2021 RAV4 Hybrid with the problem: the gas gauge needle stops around 3/4 to 7/8 at the click, and the low-fuel light comes on early. Some owners say the gauge read empty with 4 to 5 gallons still in the tank.
• After a fuel sender fix: one 2020 RAV4 Hybrid Limited owner put in 10.8 gallons at 39 miles to empty. Then the gauge read full, with 581 miles on Distance to Empty. That's what a correct fuel sender and a normal reserve look like.
• The "Refuel" message: Toyota's manual says the Refuel message means the car can't work out a range, and you should get gas right away.

And if you like tracking every tank, the RAV4 Hybrid's Tank Average mpg resets on its own at every fill-up. I cover where to find Tank Average in my hidden features guide. And my RAV4 Hybrid mpg guide shows how to work out your mpg by hand at the pump. Working it out by hand is also the cleanest way to log gallons for Toyota's test.

How to check a RAV4 Hybrid's VIN for the gas tank fix

So this is the part that trips up used buyers the most. The usual online lookups may not show the gas tank programs at all.

1. Call or visit any Toyota dealer's service desk with the VIN. Dealers can see whether a car is eligible for 20TE04, 20TE05 or 20TE06, and whether a past claim was made, in Toyota's dealer warranty system. You can also call Toyota at 1-888-270-9371, the number in Toyota's program letters. A Toyota service desk is the most reliable check.
2. Run the VIN at toyota.com/recall for recalls. But keep in mind that Toyota's lookup covers safety recalls and service campaigns, and a Customer Support Program like 20TE04 isn't one of the types it lists. So a blank result there doesn't prove the gas tank program doesn't apply.
3. The NHTSA recall lookup shows safety recalls only. The NHTSA lookup won't show the gas tank programs either.
4. A car history report like CARFAX may list "fuel tank replaced" if the dealer reported it. But that isn't guaranteed.
5. Ask the seller for the repair order, and read the labor code using the table below.

So a repair order that says "20TE04" doesn't mean the car got new parts. If the labor code is an inspection-only code, the RAV4 Hybrid passed Toyota's test and kept its original gas tank and fuel sender.

And the simplest check needs no paperwork at all. Drive until the low-fuel light comes on, fill until the first click, and read the pump. You can't usually do the fill test on a test drive, but you can ask the seller to do it, or do it yourself in the first week you own the car.

Does the gas tank problem matter on a used 2019 or 2020 RAV4 Hybrid?

So for most buyers, the gas tank problem is an annoyance, not a reason to walk away. The mpg is the same, the gas tank problem isn't a safety recall, and Toyota fixes the gas tank for free if the car is under 8 years or 100,000 miles and fails the test. And after the fix, most RAV4 Hybrids go about 420 to 450 miles between fill-ups at 38 mpg.

But the gas tank problem matters more in a couple of cases. If you drive 25,000 to 50,000 miles a year, like a lot of rideshare drivers, a RAV4 Hybrid that was never fixed means about one extra fill-up every 1,500 miles. And a 2019 or 2020 RAV4 Hybrid that's already past 100,000 miles can't get the free fix. And if you camp or drive far from gas stations, I'd plan fuel stops around 350 miles on a 2019 to early 2021 RAV4 Hybrid. I wouldn't go by the Distance to Empty number.

Now here's what I'd do before buying a used 2019 to 2021 RAV4 Hybrid:

• Have a Toyota service desk check the VIN for 20TE04, 20TE05 and 20TE06, and ask the seller for the repair order with the labor code.
• If you're buying from a Toyota dealer, ask for the program disclosure form. Toyota expects its dealers to give buyers that form, plus Toyota's letter to owners, on any covered RAV4 Hybrid they sell, new or used.
• Check the coverage left. A 2019 RAV4 Hybrid bought in 2026 may have under a year of coverage left, so do the low-fuel-light fill test in your first week.
• Don't rule out a rebuilt or salvage title RAV4 Hybrid just because of the gas tank, since rebuilt and salvage title RAV4 Hybrids still qualify for the free fix.

And my RAV4 years to avoid guide covers everything else to check on a 2019 or 2020 RAV4 Hybrid, including the separate fuel pump program.

The RAV4 Hybrid gas tank lawsuit: what owners got

So the short answer is that owners in general got nothing from the lawsuit. There was no class settlement, no claim form and no payout. Only the owners named in the lawsuit settled, and they did it privately.

Here's what happened. The case is called In re Toyota RAV4 Hybrid Fuel Tank Litigation, and it was in federal court in Northern California, case 3:20-cv-00337, with Judge Edward M. Chen. The first lawsuit was filed on January 15, 2020. Other lawsuits, including one filed in Los Angeles, were folded into the Northern California case.

• What the owners claimed: 39 owners from 29 states sued for everyone who bought or leased a 2019, 2020 or 2021 RAV4 Hybrid or a 2021 RAV4 Prime. They said Toyota advertised 14.5 gallons when the tank actually held 8 to 11 gallons, cutting the range to 330 to 470 miles.
• What the judge said about the fix: In December 2021, the judge found Toyota's fix plausibly solved the problem. The judge also repeated an earlier ruling that having to fill up more often isn't enough harm by itself. Many claims were thrown out, but some state consumer and warranty claims went on.
• How it ended: The two sides signed a deal on May 5, 2022, and the named owners dropped their claims for good. The judge had the two sides show that dropping the class claims wouldn't hurt other owners. The case closed on August 5, 2022, and no class was ever certified. One of the owners' law firms, Berger Montague, says the case ended in a confidential settlement, so the amount isn't public.

Basically, since no class was ever approved, other owners didn't give up their own rights through that case. But for most owners, the real remedy is Toyota's free fix while the RAV4 Hybrid is under 8 years and 100,000 miles. And if you want to sue on your own, you'd need to talk to a lawyer.

Now there was also a separate case in Texas, Pulkrabek v. Toyota Motor Sales, filed February 13, 2020, about 2019 to 2021 RAV4 Hybrid gas gauges reading wrong. The Texas case ended when both sides asked the court to dismiss it, and the judge did on February 8, 2022. Some sites call the Texas case settled, but the court record only shows the joint dismissal.

And don't mix the gas tank lawsuit up with the fuel pump settlement. The 2019 and 2020 RAV4 fuel pump case was about a different part, the low-pressure fuel pump, under Toyota programs 23TE04 and 23TE05. I cover the fuel pump in my RAV4 years to avoid guide.

The later RAV4 Hybrid, the RAV4 Prime and the gas RAV4

So here's how every other RAV4 compares on the gas tank, as of October 2026.

The 2023 RAV4 Hybrid gas gauge bulletin (T-SB-0042-24)

So Toyota's bulletin T-SB-0042-24, from May 1, 2024, covers some 2023 RAV4 Hybrids where the gas gauge reads 3/4 to 7/8 full after a complete fill-up. The 2023 bulletin only applies to 2023 RAV4 Hybrids built in Kentucky before a production change. A Kentucky-built RAV4 has a VIN that starts with 4T3. Basically, the dealer measures the height of a part on top of the gas tank, and if the tank is bent out of shape, the dealer replaces it.

But keep in mind that the 2023 bulletin isn't a program like 20TE04. The 2023 tank repair is only covered by Toyota's basic warranty of 3 years or 36,000 miles. A 2023 RAV4 Hybrid sold with California emissions in a state that follows California's rules gets 7 years or 70,000 miles. And most 2023 RAV4 Hybrids are now past 3 years, so most owners would pay for the 2023 tank repair themselves.

The RAV4 Prime

Now RAV4 Prime owners report the same kind of short fill, but Toyota hasn't acknowledged a problem on the RAV4 Prime. One 2021 RAV4 Prime owner says Toyota engineers told them they'd seen the trend on other RAV4 Primes, and another owner's dealer called the short fill working as intended. Andrew Egan's RAV4 Prime video shows 10.74 gallons going in after the low-fuel light. And a 2021 RAV4 Prime owner was one of the owners in the lawsuit. But the judge said nothing showed that Toyota knew about a RAV4 Prime problem before that owner bought.

The 2026 RAV4

So the 2026 RAV4 Hybrid and Plug-in Hybrid have no gas tank fill complaints so far. Toyota's Tech Tip T-TT-0800-26, from May 20, 2026, says some 2026 RAV4 Hybrids and Plug-in Hybrids may show a Distance to Empty that's higher than expected at the first fill-up. Basically, Distance to Empty uses a learned average, and the dealer can reset that learned average. That's the opposite of the 2019 problem, and it's only a display issue. And nothing announced for the 2027 RAV4 touches the gas tank.

And one more thing that sometimes gets mixed up with the gas tank problem. Toyota bulletin T-SB-0033-23 covers a check engine light on 2021 to 2023 RAV4 Hybrids and RAV4 Primes, from parts in the fuel vapor system. That bulletin is about a warning light, not a short fill.

Filling tricks for the RAV4 Hybrid: which are safe and which aren't

So Toyota's rule is in every 2019 to 2026 RAV4 Hybrid owner's manual and every program letter. Stop filling when the nozzle clicks off, and don't top off. Toyota's manual says that's to keep gas from overflowing out of the tank, and that spilled gas can damage the emissions system and the paint.

Safe filling habits that can help

• Turn the RAV4 Hybrid off before you fill. Toyota's manual says the gas gauge and Distance to Empty may not update if the car is still on. That explains a lot of "the gauge didn't move" reports.
• Press the fuel door button and wait. The RAV4 Hybrid's gas tank is sealed, so the tank has to let out pressure before the fuel door opens. The door opens within about 10 seconds, and the dash shows the progress. Then open the gas cap slowly, because a whoosh is normal. The fuel door button and the emergency fuel door release are in my hidden features guide.
• Finish filling within 30 minutes. Toyota's manual says that after 30 minutes a valve inside closes, and gas may overflow if you keep filling. So if you go inside and come back to add more, press the fuel door button again first.
• Push the nozzle all the way in. Toyota's manual warns that if the rubber boot on the nozzle presses on the fuel door lock, a valve may close and gas may spill.
• Try a different pump or gas station. Toyota says the gallons that go in vary from nozzle to nozzle and station to station. And owners say the fast pumps tend to click off sooner.
• Fill on level ground. Owners suggest it, and Toyota's manual says the fuel needed to restart after running out can vary on a slope. So filling on level ground may not do much, but it's harmless.
• Fill at or before the low-fuel light every time, and log the gallons and miles. That's the same test Toyota uses, so your log is ready if you ever need the dealer. Fuelly is a free site where you can log every fill-up.
• Get the free fix if you get under 9.8 gallons after the light and the car is under 8 years and 100,000 miles.

Squeezing once more after the click

Now some owners wait a few seconds after the first click and squeeze the handle once more. One owner says that adds about another gallon. But Toyota says not to, because the space at the top of the tank is there to keep gas from splashing back and overflowing. So I'd stick with the first click.

Filling tricks that aren't safe

• Trickle-filling past the click. Basically, trickle-filling means holding the handle at the slowest setting to keep feeding gas into the filler neck after the nozzle clicks off. Of the 2019 to 2021 RAV4 Hybrid complaints filed with NHTSA, 31 mention trickling or topping off. At least 6 describe gas spilling or surging back out. AAA says topping off can push liquid gas into the charcoal canister, the part that catches gas fumes from the tank. That can ruin the canister and turn on the check engine light. One owner, David Garzoli, trickled a 2020 RAV4 Hybrid Limited past 15 gallons in a video, and David says that trickle-filling is probably not safe.
• Rocking or bouncing the car at the pump. Some owners have tried bouncing the RAV4 Hybrid up and down to fit more gas in. Bouncing the car doesn't fix the gas tank, and it can spill gas.
• Running the RAV4 Hybrid out of gas to use the "hidden" gallons. Toyota's manual says that if the RAV4 Hybrid runs out, you need to add at least enough gas to turn off the low-fuel light. If you add less, the hybrid system may not start. Toyota puts that amount at about 2.3 gallons. Toyota Fixation ran a RAV4 Hybrid dry on purpose in a video. The car shut down with a "steering power low" warning and wouldn't restart until the stored warning codes were cleared.

Videos about the RAV4 Hybrid gas tank problem

So hopefully this helps you figure out whether your RAV4 Hybrid's gas tank actually has the problem, and how to get the free fix before Toyota's coverage runs out.
