Chris is Wrong, Don’t Try to Replace This on Your Car (It Can Kill You)


rev up your engines this is a car that I
would never buy used but I would buy new Toyota Prius
now they’ve been making Toyota Priuses for 23 years now they’ve sold over 6
point 1 million of these Prius hybrid so far and if you know anything about
Toyota they generally try to perfect things over time they don’t throw the
baby away with the bathwater they see a problem they tend to fix it over time at the heart of the prius we look under the good it’s different than most car it’s got a Hybrid Synergy Drive it’s got a gasoline engine in
conjunction with electric batteries and a generator and it’s just system that
makes it a good new car to buy but a bad car to buy used with higher mileage not
as naughty as it sounds think you better gas mileage in stop and go traffic and in town that you do on the highway they regenerate power when the car is
slowing down it uses generators in the braking system to recharge the battery
and then when you take off it uses the battery to help boost the power of the
vehicle now if you drive like a real snail you can go a little distance here
and there by just having it in an electric mode but as soon as you really
step on the gas to take off the gasoline engine up turn on not the exception to
this is the Prius prime it was a plug-in hybrid you could run on electricity
alone or use the engine but really the electricity max it would gonna be about 25 miles so it really was still just a hybrid gasoline-electric but in order to
get this phenomenal gas mileage in town the gasoline engine has to sync with the
computers and the battery and the electric motor inside to make it run
right you can see on a dash here it tells you what’s happening how it’s
charging there’s various levels that you can check out on the displays you can
see here there’s all kinds of information that you can get it’s kind
of wild if you’re really a tech person you know you’re gonna have fun playing
around with stuff here we go here it’s showing how it’s charging what it’s working on it
needless to say it’s a very complex computer on
operation but in a case of this 2011 hey it said over a hundred thousand miles
are pretty much trouble-free operation so far but with a disclaimer here up to
today now it’s got a problem with the regenerative braking system that can end
up costing a small fortune to fix aren’t you seeing a use one has over a hundred
thousand miles on it that can often be a big mistake
that’s one reason they’re so cheap to buy used I had a customer a couple of
years ago buy used one with one hundred and forty
thousand miles on it for fifteen hundred dollars they thought what a deal until
the generator went out now on a normal car my old Celica the alternator charges the battery I can replace an alternator on one of these things for less than a couple hundred bucks but not so on this
Prius because it doesn’t have an alternator it’s got a generator it’s a
generator motor it generates electricity and it run stuff and to make things even
more complicated these priuses are combination of alternating electricity
and direct electricity they’re very very very complex machines they’re not
something a do-it-yourselfer or corner guy to gas stations gonna be able
to figure out when they have a serious problem with the drivetrain system in
the case of my customer the generator which is hidden why inside here on the
transmission transactional assembly went bad and it was going to cost over fifty
nine hundred bucks to replace it because of this cramped design the engine and
the transmission assembly has to be removed as a unit and then you have to
replace the generator assembly transaxle put it all back in 59 er bucks for car
that the guy paid $1,500 for needless to say he ended up junk in the car he
didn’t bother fixing but on a positive side he had 150,000 miles on it or so
too so it lasted a long time for the original owner that’s why if you’re
gonna buy one of these things you buy it brand new you don’t buy a used one with
higher mileage now being a hybrid car it’s got a huge battery pack you take
all this crap out here then you can see the battery pack that’s
the side of it here you notice this orange when you see orange on this
that’s the high voltage electricity normal cars have 12 volt batteries now
you can stick your tongue on them touch them and nothing’s gonna happen but these are
over 200 volts they can kill you that is a particular turn off when you pull on
that switch you can shut the power of the battery off so somebody’s working on
a car they don’t like refute themselves as orange wires here same thing it’s
warning you that’s the super-high power you don’t mess with that stuff
you need serious electricians equipment for that stuff you gotta have inner
gloves and then you have to have outer gloves that are sealed young blow them
up before you test and see if they have leaks if they have leaks you throw them
away by another set and you have to have very expensive analytical gauges to work
on these things and if you were planning on testing these systems and working on
them yourself you’d have to buy all of that equipment the gloves and everything
but you’d also have to buy some very expensive gauges you need very low
testing equipment to test some of the circuits and also very high for the
200-plus of all parts of the system so you’d be spending thousands and
thousands on tools really it’s dangerous stuff I don’t advise so many
messing around with it unless they have a lot of knowledge of electricity now
going back to the battery pack they have a certain lifespan they generally last
quite some time ten years or more is not on uncommon on these things but when they do go bad then you’re in a real bizarre situation now the last time I
priced the battery for a car like this a real brand new one from Toyota was over
three thousand dollars now of course there’s guys that refurbished them
sometimes those cost as little as $1,100 a little there’s still a lot of money
but they’re not all that dependable realize it’s better and this is actually
a battery pack it’s a bunch of smaller batteries connected together so when
they go bad some of those battery cells go bad and there’s all kinds of
equipment and analyzed it would tell you which battery cells are bad
so which ones you’d have to take out and replace and solder back in even if
that’s done correctly and that’s a big if right there but
enough the bad ones are taken away you still got half or more of the old ones
in there that are old and wearing so they never last as long as the original
I’ve had customers get 12 13 14 years out of the original Toyota battery I’ve
seen people put in those refurbished ones year and a half two years later
they go bad and you’re back to square one another reason I tell people don’t
buy a high mileage used Prius you’re just gambling but in their defense for a
new one and maybe small engines but man combined with the electric motor
they are very zippy little cars they get up and go of course you have the image
of the Eco people and since the main driving force of this is the gasoline
engine it’s an it gets in cycle it’s a little differently regulated but it’s
got spark plugs and the air filter you can maintain it yourself like any
gasoline engine don’t be scared away by the idea that it’s a different
gasoline engine that’s just a design that started a long time ago and it was
never popular because even though it was more efficient and got better fuel
mileage it also had less power so they were never popular until now because
when you add the gasoline engine with the battery pack an electric motor
running it because even though this little engine only puts
out 73 horsepower the electric motor adds an additional 60 horsepower so it
almost doubles the power and that’s plenty of power combined to make this
thing zip along so in this case when you want gas mileage on a highway it’s only
running let’s see how many horsepower engine but when you want to accelerate
on a highway or accelerate and stop and go traffic the electric motor adds an
additional 60 so it almost doubles the horsepower and if you know anything
about electric motors they have instant torque so they’re actually better for
acceleration in gasoline engines so when you need to accelerate that electronic
motor gives it a ton of boost so there’s zippy little cars get great
gas mileage as you can see inside there are comfy they have cool designs up
there’s no regular transmission so there’s a big hole there and you go to
the back seat there’s a decent amount of room and then even a trunk
that’s good space because they put the battery mid there so you still got a lot
of room all around it for stuff you see what their split rear window in the back
they got top class and bottom glass so there’s no blind spots you can see quite
well behind some of these cars man they got blind spots everywhere but this is
well made they even got little peek holes in the left and the right so just
like a Swiss watch these things hum along quite well but exactly the same as
a Swiss watch when they do break you better start opening up your wallet
because they are not cheap vehicles to repair I’ve never had a single customer
buy a brand new Prius and not be happy with the vehicle but I’ve had a whole
bunch that bought them used and said I’m never buying another one of
these things cost a fortune to repair which is why I tell my own customers
when they’re looking for used cars you buy two used car
don’t buy a hybrid version you want a camry get one with just a regular
gasoline don’t get a hybrid there’s just so much complexity you get older it
costs so much money to fix and there’s very few guys who actually know how to
work on them correctly even more so than normal cars batteries go bad over time
even if they’re just sitting there sometimes it did you say yeah they go
bad even faster maybe you find a 15 year old Prius it’s only got 60,000 miles on
it still it’s probably not a good idea to buy one or pay much money for one
because that battery is probably gonna go out for any soon and if somebody
tries to sell you used one and says well I just replaced the battery last year
hey I’m assuming they replaced therefore one of these refurbished batteries and
they generally go out after a year or two or three they’re not gonna last 10
years or more like the original one did so if you are thinking about buying a
used one the battery has been replaced get the paperwork for it to see what
type of battery was put in it was a brand new toyota one perfectly fine but if
it’s a refurbished one yeah I’d look elsewhere myself and I and all
the truths about Toyota Priuses the good the bad and the ugly so you can make a
wise decision so if you never want to miss another one
of my new car repair videos, remember to ring that Bell

  • My problem with Chris’s Prius battery replacement video is that he’s encouraging DIY amateurs to mess with high voltage electrical systems. This is not like a DIY brake job, only trained mechanics who understand electrical system should mess with hybrid batteries. It’s like teaching an amateur to rewire their house electric and fuse box with one video, just pay a professional to do it, it’s extremely dangerous if not done correctly: link to video in question: https://youtu.be/Q3RCdrh666w

  • Scotty, I found a 1991 Nissan D21 4cyl for $1500. Owner says the truck runs great except for an oil leak. Has around 200k miles. Is it worth looking at?

  • Get one off-lease and save a lot. Has plenty of reliable years left and much less outlay, so you start saving over gasoline car sooner.

  • Scotty is working and explaining the car i drove 😍 almost 200k and still worry free.. I don’t drive like maniac but not like a snail too

  • Scotty help me out. Tried to change my power steering fluid. I sucked out fluid in reservoir then told my wife to cut the car to on and move the wheel to refill the reservoir. She started the engine and tried to move it before i could say stop. Now the pumps whining and won’t take in any fluid. What do i do? I think it’s full of air now

  • Scotty, your bang on on this one. And some of these packs are Lithium batteries. Those get SUPER angry if you short them out trying to rebuild a pack of cells.

    Honestly, if you gotta replace a battery in one of these, buy a new battery pack complete from a dealer. Yes, its twice the cost. Sometimes 3 times as much, but if you dont absolutely know 100% what you're doing it could cost you way more.

  • Scotty I agree totally,I’ve owned three Priuses the first a 2005 bought new lasted to 237000 miles but the battery started giving trouble @ 180000 the second one’s abs module went out at 160k the third one’s ac compressor went out at 140k and took the inverter with it.the local ac shops wouldn’t touch it because of the compressor is hv electric. The local toyota dealer here in Victoria tx wanted over $6000 to fix the ac on a $2500 car……… what would be really helpful is a list of shops that do work on these cars.there has to be some out there? Especially in Houston or Austin.heck in Austin you can’t throw a rock without hitting a prius,I mean there’s a lot of these cars on the road there’s got to be some options besides the dealer

  • I could hang a Prius on davits as a spare car on the back of my ‘75 Olds Ninety-Eight (that has 455 cubic inches of V8 power to move all that steel forward)

  • It’s not a rocket science like Scotty tells. Don’t he think that YouTube is goig to be FULL of videos how to safely work on your electric car? DIY on electric cars are going to be a huge deal and people like Scotty don’t like it because they promote old, unreliable technology (gasoline cars).

  • I replaced my main battery and was one of the easiest things to replace. Grab one from the junk yard $800. I noticed my old battery would of been fine if I kept my battery fan clean. My Prius has 340 k miles.

  • Problem is, it’s not just the prius. There are rav4s, highlander hybrids. Not to mention each manufacturer has at least one electrical vehicle.

  • Scotty has to save face so ill speak on his behalf. Dont buy a Toyota Prius. They are fine cars when theyre new, but as they get older they can turn into a giant money pit.

  • Prius suck there drivers are all douchy douches the guys on roadkill drove a tank over a prius great use of a prius ha ha ha i like my vehicles to be a gross polluters myself 1st generation 4runner z31 nissan z foxbody mustang sentra as a daily driver

  • I bought my used 2015 Prius at 65K miles two years ago last November specifically for Uber/Lyft driving. I'm at over 167K, I get 47 MPG driving up and down San Francisco's steepest hills on power mode all day. Fluids, filters, tires and pads. That's all I've had to deal with. Replaced the brake pads at 120K which is typical for a '15 Prius. Still waiting on all this doom and gloom. I know the battery will go out, expecting that at 250K.

  • Scottys right the 90s toyota celica is a great car its not a 10 second 1/4 mile car but i think the 4afe engine is as good as a 22r 22re

  • Rev up your used generator charged lithium battery packed with tiny atkinson cycled ,Filled up with ''HELL'' gasoline hybrid engines!!

  • I bought a used 2015 Prius with 20k miles for 15k USD. Saved 10k. Wonderful car. Easy to service oil , filter, along with coolant, tran fluid, brake fluid.Never buy new. Too much money. Perfect for local drive

  • I got a 2017 Corolla Hybrid. Bought it new, it now has 22,000 km or  14,000 miles. Goes like a dream and very fuel efficient. I probably will replace it 2 years as not to loose too much in depreciation. This will also give the future owner a lot of life in the battery as well.

  • Scotty I have a 2013 Dodge Charger rt it has the code of p3449 is this a easy fix for someone that doesn’t work on cars? Or can I just live with that code?

  • i have a friend who bought a 2015 in 2017 @ 30k and hes already at 300k on it know he does alot of driving i keep woundering when its going to start costing him money to start fixing it

  • I had a 2010 Prius and it was a fine car but after getting over a 100k on it the brake pressure accumulator was cycling all the time. There was an extended warranty on it but I didn't want to deal with it as they are around $3 to $4k to fix due to its proximity. So what is a brake pressure accumulator?? Since a Prius engine doesn't run all the time you have to have a pump for the power brake booster. I traded it and bought a traditional Camry with a 4 banger that has 40% thermal efficiency and I get 40 mpg on the highway and great driveability with 203 HP. Yes, 203 HP out of a non-turbo 4 banger.

  • I'm relieved to hear that I didn't give some advice of a questionable nature.
    Something about electricity most people don't know: #1) one of the first things is that voltage and wattage don't kill you. It's the amperage. It only takes .6 amps for a fatal shock.

  • My brother in law bought a a 2009 prius with about 120k for $7500 3 years ago. So far it's good. I guess. I Dont personally like those cars. They are WAY overhyped

  • My Ford Escape Hybrid 2012 has over 500,000 miles on it with the original hybrid battery and engine and transmission.

  • Hey Scotty what is your take on the newish BMW i8 turbo charged 3 cylnider hybrid? You know the one that was in the Tom Cruise movie Mission Impossible?

    Cheers from Canada

  • that brake abs trac lights take it to a dealership asap they'll fix the booster for free there's a enchanced warranty on it like so more people can see

  • I've been buying used priuses for the past five years. It's very reliable and if it's breaks it is cheap to fix even the hybrid battery costs about $400 to fix. I have a fleet of 11 priuses (gen 2 and 3). Awesome cars

  • 2013 prius with 159,000 miles and I have only done oil changes and air filter changes. I still have original brakes and I am a uber driver.

  • Pull the service plug & wait an hour!! Really not as scary as your making it. I rebuilt my hv battery pack in two days. Dangerous? It can be! Wear HV gloves and do your research!!

  • Any rubber gloves will stop 200v. Long sleeves or long gloves like Scotty's. Do buy a refurbished battery but keep the old one to canableize for cells. The dead cells will get hot when you drive.
    Disconnecting the bar in the middle chopping the voltage in half. Split the 2 100v pack in the same way. Clean the bars and contacts. Like a 12v lead acid.
    Yes 200v can kill you but a 120Vrms plug has a 170Vpeak voltage and electricians rarely wear gloves. So do be careful.

  • I’m surprised that he didn’t bring up the cvt that he doesn’t like. They are kind of zippy when it’s in power mode. I never got the mpg that was advertised and only got near it on the highway and I tried very hard. I don’t think the computer was programmed properly when it was new and was given a rental when I took delivery because they couldn’t figure out why the radio didn’t work. After a while I complained to the dealer about the mpg but he insinuated that I must be beating on it. He said there’s nothing wrong with the computer and wanted to charge me to check the fuel system. I made a corporate complaint and they said they don’t do anything about mpg complaints. I still have the car and it’s been very reliable. It’s almost 10 years old with 109,000 miles and now the city driving mpg is down to 36 in the winter. I think it’s time to find out what it’s worth.

  • Generators almost never fail on the Prius inverters go bad i replace them all the time misdiagnoses i can assure you we rebuild the batters all the time with a regular volt meter and we use disposable gloves and screwdrivers covered and sockets covered with tape battery cells cost 40 each we charge 1000 to remove rebuilt & replace and Guarantee job for one year and there is no soldering involved each cell Bolts in

  • Very true. My 2016 Prius C was bought new and I like getting the 50+ MPG and the acceleration. It's low COG and and 2500 lb weight let it handle like a poor man's sports car. Unfortunately it also rides like one, ie. a little firm (rough). Praying I dont have to replace the starter/motor generator.

  • I wonder if Scotty only has to pay 1/2 price for a haircut being that he only has hair on the back of his head. He's got that old man mullet.

  • Electric cars are easy to fix and safe to repair if you are properly trained- but one wrong move, one wrong step taken and you are toast- not zapped, fried, you can't let go of ]high voltage DC, you sit and smoke till someone pries your crispy corpse off of it.

  • I would never ever buy a Prius used or new. New is FAR too expensive for the lack horsepower, lack of storage capacity, and eventual battery replacement needed. You're saving money on gas but also spending an extra 7 grand for it, so what's the point?? Buying used is a bad idea for all the reasons Scotty says, AND the battery life. I've owned my 05' Corolla for 14 years, am on 150k miles, and have only changed the battery once, did it myself and it cost me about $150.

  • On any older machine the electronics are the first and most expensive things to fail. So a hybrid or E machine, the first thing to go is the whole damn car! Throw it out like an old I phone, not very green if you think about it.

  • Why do everyone who buys these cars lose the ability to drive? Most annoying cars on the highway! 150,000 miles is nothing! What a pile of garbage!

  • Thankyou Scotty !!! I’ve had my “2014 Sonata Hybrid Limited” for about 5 yrs now with 70,100 miles on it. @ 58,000 miles it needed an Expensive Repair to Replace the HPCU, (Hybrid Power Control Unit). Well, I was told 3 Different Mileage Warranty Periods for This Main Onboard Computer. One by the dealer who replaced it,(60,000 Miles),…& 2 different quotes from Hyundai Corporate,….100,000 miles, & 150,000. Another words I wasn’t able to get a Truthful answer on this !!!🤪😳 I Just squeaked under the 60,000 Mark, so they replaced it “free of charge”,…it would have Been a $4,500 Cost to me,….OUCH !!! 🤪🤨🧐 I love the Driveability of This Car & all the Amenities it has afforded me, but I’m not looking forward to any upcoming Expensive Repairs !! So, Guess I’ll Be Buying “new again” rather than whenever I’m Faced with an overly expensive repair. Thanks again SCOTTY !!👍👍🤗
