    So, we'll never know if you actually 'Fixed the Problem'.
    To actually know that, you'd have to rack up +250k miles on your Prius.
    You probably won't do that. So,,, I thus, I put you on block. Not really.....;)

    It was this head gasket 'Problem' that made me dump my last Gen 3.
    I fixed the problem by getting two cars that don't have head gaskets!(y)
    My third car is a Honda. No chronic head gasket problems there.

    Honda engines usually has no issue until they start turboing. But the V6 with cylinder deactivation are always problematic. Honda has their own problems and in the past their transmission are really weak especially the CVT in hybrid. Their newer hybrid system transmission better without belt.
    Honda is famous on their manual gear and R lines. Better deal than Toyota (subaru/BMW) offer for manual sport car. The best of Toyota is Yaris GR that is not available in USA.

    I believe there is ~ 10-20 % of head gasket issue in 2010-2014 Prius but still not 70% unlike Honda HV battery, Transmission in V6, oil burning in cylinder deactivation, and fragile belt CVT hybrid.

    I still doubt about newer Honda these days. I don't like turbo engines and direct injection only. Cleaning intake valves is more expensive than 120k miles EGR valve cleaning. I prefer D4S Toyota system without turbo and 41% thermal efficiency

    I don't know how one could come up with numbers like that once old very high mileage Gen 3's are scattered around the outback.

    I have no allegiance to any brand. I was just joking about my Element that sits around rarely used and unloved. I mainly buy used and look for bargains that have very low TCO. Thus the EV's!(y)`

    I am not sure about EV besides Tesla. The electricity vs gasoline price is not that far per miles with hybrid. Hybrid has no degradation in range and cheaper.
    500 miles range is consistent in both winter and summer. Winter in EV cause mental breakdown worrying the range.
    Typical budget EV like Nissan Leaf are so bad and battery capacity degrade so fast to the point it is unusable after 200k miles. GM and Hyundai are like landmines, can burn down your home at any time. Disposable european cars may have better EV than their turbo cars.

    I think regular gasoline Toyota is still the best deal in 5-8 years used market. Gasoline is cheap in USA. Reliability without hybrid or turbo may be more cost effective for used car lovers.

    In Europe, gasoline cost 3x more and hybrid makes sense and Toyota sold 70% as hybrid.

    1. You can't make gasoline on your roof.:cool:
    Next you'll say EV's are dirtier. I know exactly where my electricity comes from. High percentage renewables. You can look up the recipe of your local electricity.
    Also, look up 'Well to Wheel' and 'Windmill/Solar Panel to Wheel'.

    2. Maybe winters are very different where you live. This is false for most.:unsure:

    3. Somehow, driving EV since '15 I have dodged this bullet...:ROFLMAO:

    4. OK, I'll bite.. What is the range on a Leaf at 200k miles?(n)
    (you know it depends a lot on the particular way a Leaf has been used and where.)

    5. Wow, no kidding? Do you have numbers and ,,, never mind, I know where you get your news from....:whistle:

    6. OK !! We agree on one thing! Why are we not taxing it the way all other industrialized countries are?
    We could use some infrastructure improvements and basic maintenance, you know?

    I'll try to stay apolitical on this, and this may not be news here, but I recently bought a Gen 2 Prius from a guy in Virginia who shared this story.

    Higher gas prices, regardless of causation, have had the effect of driving more and more citizens to purchase more fuel efficient motor vehicles. Okay, nothing weird or screwy with that, it seems a perfectly logical reaction that a majority of folks have long supported in order to lessen our dependence on oil. Environmentally, any rational being would see this as a good thing, but not the State of Virginia (and I believe there are other Sates that share this perspective). They see it as a very serious problem, because higher fuel efficiency means that people are of course buying less gasoline, and since the State demands a significant tax on every gallon of said fuel, less gallons sold means less tax revenue collected.

    I would add at this juncture that Virginia has pretty affordable gas prices compared to its northern neighbors, so it would seem that a reasonable "fix" (assuming they have no desire to spend less taxpayer money) would be to simply increase their gas tax to a level closer to that of other nearby States. Heading south this is not the case, but a rather significant dichotomy within the State is that Northern Virginia is generally looked upon as being a completely different entity by most of the folks across the rest of the State, thanks in large part to the greater concentration of wealth resultant from the huge presence of very well paid Federal employees surrounding D.C.

    So, their proposed work-around (and I'm not sure but this may in fact have already been made law) is to impose a use tax of some sort that would charge people for every mile that they drive, thereby taking the pressure off of gasoline to provide their desired revenues. Since the continuing sprawl of the D.C. bedroom community effect in the north has led to many commuting from as far away as Richmond, the new tax would certainly bear most significantly on that specific group of taxpayers. The sponsors of the bill supposedly cited the continuing growth of EV and hybrid market share as their basis.

    Since I don't live there I'm personally ambivalent to this supposed development, but I do find it interesting all the same. I can already see a wealth of difficulties with trying to justly assign such a tax. While on the one hand it may seem perfectly fair to have people who use the roads and bridges pay their fair share, I'm curious how they intend to collect from people who simply drive through their State, or what about folks who live in Virginia but do most of or a considerable amount of driving in adjoining States? I would assume that there would have to be some sort of routine State auditing of people's odometers, so piling up miles on N.C. or Maryland roads would seem unfair, but then there's the issue of trying to collect a tax after the fact. The reason that the Federal government collects our income taxes as we earn them is because they recognized that trying to collect it all at once at year's end would probably lead to open revolt and non-payment, so this looks to me to be more of a problem in and of itself than a solution, but it does provide a way for the citizenry of central and southern Virginia to stick it to the residents of the north. Funnily enough, that higher concentration of wealth in the north is already paying an outsized portion of the State budget, but like I said, it's interesting to me to get to watch it all from afar. ;)

    Can't wait to see what moves the rest of the stable geniuses make.

    . The point you are possibly missing under the guise of someone else's opinion is gas taxes are supposed to pay for the roads. Economy cars and evs mess with the equation but was not an issue until the majority started adapting. Larger license fees for hybrids and evs will happen.

    By the way a lot of upper middle class, business owners and corporations write big checks after the fact. The most likely revolutionaries never pay significant taxes. Most are slightly off.

    Sales taxes are designed to capture a chunk of everyone's spending regardless of how it was acquired. It is a progressive tax hitting the lower middle class and poor harder.

    In Texas, sales and the big one, property tax leads to multi billion dollar surpluses they then argue how to spend. Even undocumented pay sales and property taxes, build our houses and do all sorts of hard work. Regardless of bluster, no one bothers them.

    No 'guise", but so goes making assumptions . Not sure what your point, if any, was, but I'm not confused about how taxes are generated, I just thought the development was interesting.

    Check out Michael Orie video on you tube . Death rattle but not. Pretty good. Listen in the video the guy saying in his country spark plugs for the 2ZZ engine or $150 a piece for one.

    I suspect voice-dictation off the rails: Michael Orie has a YouTube, with about a dozen video as far as I can tell, and nothing automotive or Prius related.

    i just didn't want a wild goose chase.

    it's like the 'i had a great hybrid mechanic up in new england years ago. and i bought a new oem hybrid battery for $700. years ago' answers to serious questions. :rolleyes:

    I will be on my Aprilia Scarabeo scooter very much when this happens because I can drive one of my scooters around with no registration on it essentially and that means no taxes

    Look, No one with logical mind will buy a 5-8 years old BEV but most of us will confidently buy any hybrid 5-8 years old. Whateve we save from solar roof or any cheap alternative electricity, will not be paid off for the battery replacement cost at near the end of the battery life 8-12 years. Meanwhile most regular hybrid cost much less and most of us can afford brand new hybrid battery but not BEV. The value of the car is always way lower than the BEV battery replacement. It is just not for economical reasons, it is about hippies and environmentalist snob.
    Based on the resources alone, Toyota is greener by making 90 hybrid instead of 1 BEV and 89 pure gasoline cars in reducing the global emission.

    I'm waiting on hydrogen take off looks very promising . And E fuel looks like twill save ICE for many more years. So much so the Eu is revamping climate goals... So I'm really waiting to see e-fuels and hydrogen come into play if that staves off the ice demise for another 25 years that's past my life expectancy and into my daughters so that should be okay

    Do you know of any 8-12 yr old BEV's that have needed a 'replacement battery'?
    Do you have a source for facts about this crazy statement: "Toyota is greener by making 90 hybrid instead of 1 BEV and 89 pure gasoline cars in reducing the global emission."
    Are you saying 89 gassers putzlng around the neighborhood make less stink than 1 EV using roof top solar?

    I think I know where you find such 'facts'.....:whistle:

    Have you ever heard of the concept of Well to Wheel vs. Windmill or Solar Panel to Wheel?
    Which makes less stink? Think Oil Tanker, Suez Canal, Military Presence, Houston Oil refinery stink, etc, etc....

    My favorite saying is: You can't make gasoline on our roof top.
    Also, did you know the grid is getting cleaner every single day?


    I have a Bolt with a new pack and warranty for 8yrs/100k miles. I'm good until 2029. (y)
    Do you think EV owners wake up one day to find that pack is 'Just Dead, Jim'?
    Do you know how nice it is not stopping at the smelly QT and never scheduling an Oil Change, (DIY or down the road)?

    Luddites Unite! We don't want a cleaner, less expensive, not influenced by OPEC,,, and a ,,,,
    Just plain easier future with our transportation tools.
    We want to burn stinky liquid stuff in our inefficient engines and maintain that complicated engine with TLC.(y)

    (hydrogen is not a fuel source. It's a means to transport energy, just like a wire. It will never be efficient or affordable.)

    What's the replacement cost for the bolt EV basically in five or six years from now I imagine it'll be reasonable and I also imagine the bolt general motors to be making a battery that's not built into the frame of the vehicle that can relatively easily be swapped out kind of like the Prius where is Tesla and lucid and some of these people are incorporating the battery into frame members which means when the battery goes give up the car or what cut the floor pan out and weld in a new floor pan battery assembly?. I think GM because of their manufacturing prowess if we want to call it that we'll come up with the way to keep the battery as an add-on or mount in to the car not built into the frame that will make a huge difference in cost and the car being viable and reasonable where is these other cars are being built like zip zaps kids toys made to just chuck when you're done that to me seems quite a bit problematic I hope I'm wrong and this is not the case but it seems some of these manufacturers are doing just this
