Thank you from that brief summary of the major points. Now I鈥檓 in the map again. I have to apologise my own jaada jaada. 200 sides was too much to read that it has been explained earlier this way intelligible. I鈥檒l back of everything.

fuel tank vs. keeping myself and my family safe and healthy...

I haven't been focusing on my cars lately. Especially for a fuel tank issue that has no impact on the reliability of the car.

I got my RAV4 HV in September. I adapted to accept the 10.5 gallon maximum fill up with ~380 mile range, although I wasn鈥檛 real happy about it. (My 2013 Camry HV had a 600 mile range.) I documented the fill-up limit with my dealer one time and moved on.

NOW (after 6000 miles) I cannot fill beyond 8.3 - 8.5 gallons in the last two fills. One fill was at DTE 25, one at DTE just beyond Refuel. If I go beyond 1st click I can get 0.9 - 1.0 more gallons.

Why the sudden change?
I don鈥檛 have the gas gauge problem. After pumping to first click the gauge is at or past Full, both before and now.

If we keep quiet, Toyota will be a winner, then all of us will be losers. How about law suit in ca, does judge rule anything.
--begin sarcasm-- And now that a lot of the nation is on a 'work at home' status, a lot of manufacturing placed on 'pause' or just plain 'laid off,' I wonder who got to take the tank project home with them to solve the 'problem.' --end sarcasm--

I thought we were saving the world from catastrophic climate change with our magical hybrids and our overly-complicated and unnecessary vapor recovery system that affects our ability to fill our tanks yet it's appearing that an overwhelming majority of countries that aren't the U.S. or Canada are just spewing fuel vapors out of their tanks and into the atmosphere! Still feel like you're making a difference saving the planet? FOR SHAME!!!!!!! /sarcasm

Here's some light reading that simplifies the matter at hand.

Oh my goodness! Do we have to babysit, edit, and issue warnings on another thread because not everyone agrees and someone might be offended? If so we'll likely just close it. And there will indeed be no appeal.
I鈥檓 out of here. Tired of the moderator鈥檚 attitude. You鈥檙e not helpful to me and downright rude.

Don't see many people on this forum to discuss gas tank any more, are you guys happy with Toyota. Hybrid customer had a lot of post everywhere before, but now I don't see gas tank topic on this forum. If we keep quiet, Toyota will be a winner, then all of us will be losers. How about law suit in ca, does judge rule anything. By the way, mpg in winter in cold states is 25 to 32 mpg, how about now folks, if you're in il, wi, mn, Midwest, what's mpg now, temperature is 40 to 55 degree, are you guys getting better mpg. CA FL AZ southern states mpg always high because they don't suffer cold all year long.
I posted a complaint with feds on national highway safety website, very easy. I think thats more likely to wake up toyota than a rav4 forum post. Do the same

as someone who racked up 27k in the last six months my vehicle has sat idle for three weeks while we quarantine... as others have said we鈥檝e spoken out peace and Toyota has stated they鈥檙e working on a fix. At this time in our lives we hav more important things to worry about.
Its not off the list but it鈥檚 pretty far down there.

Sounds like that ventil is not opening enough and the gasflow is too slow. Or too narrow system overall.

Just change your gas pistol noses to working ones and everything is fine. And stop That jaada jaada Moron talk. The issue is your too sensitive airback valvesystem. Make your own engineers to sori and think A bit more and they may get an Ahaa. Not that Ihaa what now seems to bee.

:D
Welcome to my ignore list.

Yeah U think they have other problems now and we all do .
But on the last motorweek they finished the long term test and mentioned
the gas tank problem was still there and it was the only thing wrong or of irritation
with the car.

"After a few recent highway trips, we鈥檙e noticing that if you stop for gas when the fuel gauge is reading a 录-tank, the most you鈥檒l be able to put in is a little over 7-gallons. It seems the gauge is a bit pessimistic as the tank actually holds 14.5-gallons. Something we鈥檒l keep an eye on over the coming months. "

I imagine it's been quiet lately due to other priorities and concerns.

Ignore the trolls here. They jump all over people who don't have all day long to scour the site for things they insist were discussed before, and get uppity if you start a new thread on an issue.

FWIW I'd be interested in hearing the latest so am following this thread.

My current theory:

Based on looking at the way the filler hose enters the tank (not from the top but in the middle), I think you can fill at full speed for half a tank(as long as the gas in the tank is lower than the top of the filler tube), then the fuel in the tube starts hitting the fuel in the tank. It creeps up the filler tube and creates back pressure which shuts off the nozzle.

So the last portion of the fill has to be at a leisurely speed so fuel into the tank isn't blocked by the fuel already in the tank. If there is too much back pressure, the fuel backs up high into the filler tube causing the nozzle shut-off to trigger. If you do it slow enough so the fuel has time to enter the tank without overwhelming the venting system, the fuel can slowly flow into the tank.

I can't remember when I didn't hit the F mark. And looking back on it, those were times some pump jockey was in a hurry and filled for me or before I learned the slowly but surely method.

Is this optimum? No optimum would be a fill tube entering the tank from the top (not from the middle) so the back pressure didn't develop. But look at that area from underneath the car and tell us how you would redesign it given the suspension location and the need for a flat cargo floor.
I wonder if anyone has an old school farm gas tank. No pressure/vapor sensors on those. I think they all but eliminated them some years back, but if someone can get one filled with gas it would be interesting to see how they work in a car with a known problem. Have to think Toyota tried something like that already though. Although maybe that worked--and they still are trying to figure out how to retrofit a new design, as even if that worked they have to design a new system.

I think I read somewhere in the 6,000 plus posts that someone tried filling using a gas can or at least the spout and it made no difference. But maybe I am misremembering

Yes sir you are correct. This is what happens when you create multiple threads...you go over all the stuff again.

And I am one of the "trolls" that thinks its ridiculous to start multiple threads on the same subject because you are too important to read through a lengthy thread.
