Here’s Why New Toyotas are Exploding

rev up your engines it turns out that more and more Sun
roofs are exploding the ones that are made out of glass
now since 1995 in the US and Canada there’s over 1,200 reports of exploding
Sun roofs but 70% of this is since 2011 they’ve been the Toyota’s Honda’s you
name it all kinds of cars are having is exploding sunroof
so one advantages when they do explode they explode out and not in what the
engineers have come up with the conclusion is that when I make the glass
sort of sunroof it turns out that the inside part cools before the outside
part where they’re making a glass so the outside part is more brittle than the
inside part so when it breaks it breaks out instead of breaking in which is a
good thing but it can still scare the heck out of you when you’re going on a
road and I’ve said your Big Bang a lot of people look they turn the steering
wheel happen to one of my customers she’s such heard a big bang but she used her head and felt the steering that she said well
it’s still going straight it’s not wobbling or anything so she figured she
didn’t blow out a tire and then her daughter said look the Sunroof has blown
up luckily the glass blows out and not in in most cases might be a good idea
that if you do have a sunroof when you’re not using it
close the top the Sun roofs on all the good cars up top over your head there’s
a sliding piece so you don’t get the light in so you can close it when you
don’t want the light open when you do do like my wife does she hates sunroofs
anyways even though our Lexus has one she just leaves that closed the whole
time so the light doesn’t come in because she doesn’t like the light
coming from the top anyway so there might not be a bad idea for all you
people out there that have sunroofs if you’re not using them but that partition
time to close it so if anything does happen none of the pieces will come
down on your head , ice says Scotty I got an 01
GMC truck Sierra 1500 4-wheel Drive I had to disconnect the battery so I could
replace the windshield squirter assembly when I put it back together it won’t
start health you know unfortunately modern
cars are getting more and more and more complex sometimes a simple thing like
disconnecting the battery cable and then when you put it back on
the car won’t start my advice is don’t ever do that again get one of those
memory saver devices you can get an autozone Amazon eBay all over the place
basically they plug into the OBD port and then out of them there’s two clips
that you hook up to a small 12-volt battery that keeps the voltage there it
keeps you from losing computer memory and that won’t happen what you do that
so now you’re stuck from my experience with those things
because it is an old Ford GMC in the dash called the body control module that has
a lot to do with the car starting the last time somebody told one of those
over I thought ok I’ve done this before I’m gonna try it again I went in the dash I
unplugged the body control module and I waited about five minutes then I plugged
the stupid thing back in and it started up and ran perfectly fine a lot of times
that’ll reset it now if it doesn’t reset it you probably have to find a guy like
me with your giant scan tool and sometimes you have to reset other things
to make it start but from my experience with those a lot of times it’s just
unplugging the body control module clip waiting about five minutes plugging it
in it can start right back up again like I say the next time you work on you
got a disconnect the battery hook up a memory saver and you know to deal with
any of that crap from now on Jerome from Philly says I got a 2000 Chevy 1500 v8
it cranks it won’t start and it says check engine oil pressure let’s hope
it’s a simple problem the way they designed those vehicles the oil pressure
sending unit if it’s low oil pressure it won’t send power to the fuel
pump you know crank but it won’t start cuz you’re not getting any fuel to the
engine it’s basically a safety feature so if you’re driving on your own you
lose oil pressure instead of the engine running until it blows up it shuts fuel
off and the engine doesn’t run anymore you want to pray that it’s just a bad
oil pressure sending unit and often is by one put it in a not that big of a
deal it just bolts out and bolts and you can like an autozone if you don’t have
the tool they’ll sell you the socket that goes on it for 10 bucks too and
replace it if that fixes is great if not then odds are you actually have low oil
pressure and your engine’s on the verge of wearing out to check that you just
put a gauge on where those oil pressure sending there goes you check the
pressure and if the pressure is zero or really low then that they’re gonna have
to rebuild the engine it’s mm you and 70 miles probably got a lot
of miles and if an engine wears out it’ll do that play it’s just oil
pressure sending you a lot of times it is because like I said if you don’t have
oil pressure it shuts the fuel pump off and if the sending unit is broken and it
tells you it’s got no pressure even though it does it won’t send any fuel
pressure lilies says I got a 2011 bmw x3 X Drive it cranks but
it doesn’t start and it’s got the code p016 crankshaft position correlation
errors those things are endless money pits as they age and I’ve seen it on
many of them that has a variable valve timing system in BMWs case it’s called
the vanos system VANOS and it’s probably the most complex variable valve
timing and I have seen many of those things where they use timing chains not
a belt where the chain goes on the sprocket with all those teeth that vanos
thing often strips and moves it was kind of a design flaw they didn’t build them all
that right so the first thing you want to do is have somebody take a valve
cover off and if they see that timing chain has ripped it off and a stupid
vanos thing is shredded to the side odds are you’re gonna need another engine
because when it does that Pistons at the valves bent the valves those are very
complex engines the last time I had a customer like that they junked the car
they said I’m not gonna fix that and the time before that I sent it to a friend
of mine who does nothing but BMWs and even he said you’re not gonna fix this
thing and he found a used engine from Germany and had that installed then it
ran fine but it costs a small fortune by the time it was all done those are not
cheap cars to fix they do break down they’re not bulletproof
they were bulletproof 30 40 years ago but they’re not anymore my advice stay away
from them Joey the Lucas says got an 2011 Kia Sorento I hear a grinding noise
check engine light comes on so did the track lights and it’s got the code C
1264 steering angle sensor circuit signal modern cars are so complicated
you got traction control you got abs brakes there’s a part called the
steering angle sensor and that measures where your steering is so it knows how
to adjust things for your traction controls so if you slam on the brakes
and it sees the cars pulling to one side then it’ll change the brakes so to go
back straight instead of pulling to one side you got a problem in that system
now you do say you have any grinding noise well my experience with those
Kia’s are whenever you get that code and you’re a grinding noise
it means the sensor is broken and it’s grinding cuz when you turn instead of it
being smooth it’s broken inside and it makes a grinding noise so if that
grinding sounds coming from your steering column odds are you’re gonna
need a steering angle sensor now you can’t do this yourself you got to take
the airbag off take it all apart but even if you did all that put it it won’t
work cuz it’s got to be reprogrammed by a guy like me with the programmer call
around and see what mechanics charge to change the steering angle sensor for
that vehicle and have them do it for you Ryan says I got an 08 chevy
Silverado my seat belts won’t retract a more modern vehicle like that is a bit
more complex than the old ones the old ones were strictly mechanical and when
they didn’t retract there’s a spring inside the retractor and it’s got a
gear and that system would break down sometimes you get lucky take it apart a
little bit with some wd-40 and getting to work again but yours is electronic so
that’s not gonna cut the mustard there is a module I would check that module
the module is very low a lot of times especially if you’ve been in any kind of
flood water or rain got in the car they get filled with water and I don’t work
so you might want to check that let’s say it’s full of water then you just
gotta replace it go to the dealer and buy it a seat belt module you might try
though if it isn’t wet open the door close the door put the can try to get it
to retract hit it with a hammer if you hit it with hammering and it starts to
retract been you know the modules bed says like you got an old toaster and you
hit it with a hammer it works you know something’s wrong inside you just
replace it because with the modules you can’t fix them you have to replace the
whole thing as a unit all these computer module systems I think there’s something
you make money fixing the cogs on a break Jerry the first says
got a 09 Ford Fusion 2.3 automatic I’ve got the code p0660 for intake manifold tuning valve control brother that is a known flaw knows the intake manifolds on those are tunable manifold so they have a little assembly that can open
close to change how much flow is inside one is for better acceleration one is
for better gas mileage and those systems just break because they were cheaply
made sad but true all that plastic junk the heat of the engine gets to it and
they stick and the only really way to fix that plastic junk is by replacing
the entire intake manifold itself you really want to try taking it apart and
trying to lubricate it but it’s all plastic and then they end up sticking
again or if you see it’s grabbing somewhere and you file it down while
you’re changing the flow of the air and the computer doesn’t know that so really
the only sure fix that I’ve ever found on those is replacing the whole intake
manifold assembly with the new one now if you could find an aftermarket one
from a company like dorm and go right ahead they’re generally well made
because they’re redesigned to work right in the first place, so if you never want

  2. It's not just on Toyota and many other auto manufacturers. The glass is temperate glass

  3. "There's a module". ❓❓❓
    Translation: it's a money pit. ☹️☹️☹️
    Diagnosis: hit it with a hammer. 😄😄😄

  4. Unfortunately, since cars are getting more complex, it is no longer do it yourself repairs

  5. My 2004 bonneville with 250,000 miles still has the original sunroof , engine and transmission……

  6. How does Scotty remember all this stuff!? God bless ya buddy. As always, love the pictures too! Lol

  7. Me: My sunroof exploded.

    Dealership: Well your problem is you have econ mode ON.

  8. Hope that does not happen to us. I assume this is a problem the further south you are. We just bought a manual transmission 2020 Corolla, the only way we could get a manual was to get a pimped out SE version with a sun roof. We just keep it closed, I'm not a fan of holes in roofs.

  9. I'm looking at a 1994 celica for 3000$ , I think I have reached my maximum scotty

  10. SUN ROOFS SUCK. Just another unneeded luxury to break. And this can happen in so many ways.

  11. I buy Toyota first choice and Honda second choice. I don't like cars with low reliability. 🙄

  12. Like 4 years ago my moms Lexus ES 350 had the sunroof blow up, I thought something had hit it but now I know that this is somewhat common. Thanks Scotty!

  13. 93 toyota truck, still have original sun roof.Sun roofs are made thinner now….cheap plastic crap!

  14. But buy this car. Whatever you do don't buy a Nissan with the not exploding sunroof.

  15. This is the problem when people get inexperienced, corporate leader climbing, engineers to design their fancy new aged sunroofs. Sunroofs have been around a long, long time. The non explosive type.

  16. I'd leased a 2004 Maxima. In 2006 without warning the sunroof shattered down or inward while driving on the highway during a light rain. Scared the bejesus out of me. Apparently there was a recall on them that i wasn't aware of.

  17. Sunroofs use tempered glass. You make tempered glass by heating it up and quickly cooling the outside which tries to shrink over the hot glass in the middle, creating surface tension – making it harder to break. The edge of the glass is its weakest point. If the edges are not properly sanded, polished or ground it can create a microfracture during tempering. The flexing of the glass can work the fracture to the point of failure. The glass probably has a slight arc to it so as the tension force is released from the edge to the middle the fragments are forced in the direction of the arc. My guess – 80% chance manufacturing error, 20% fitment/tolerance/clearance error – such as guide tracks or attachment points.

  18. hit it with a hammer ., if not working .then use biger hammer . repeat .till vented all ange

  19. If you get a sunroof in your car as an option, you deserve to have it explode on you. Sunroofs are plain stupid, especially if they are made of glass. Panoramic roofs are even worse.

  20. I found a fix.smoke a blunt and u dont need to open it for the smoke or better yet even give a s**t

  21. hey that was a sweeeet video! rocket socket huh, my bf spent a week getting off a lug lock with a cold chisel 🤣

  22. Learning mechanics, having (a lot of) fun, learning about american culture and learning some english terms (such as "odds are") with Scotty which are not so common for non native english speakers like me. Nothing better than learning and having fun. Thanks a lot!!

  23. I never once drove longer than 5 minutes with the sunroof down basically paid for nothing

  24. Yoda cars with sunroof problems HAAHAHAHAHAH That's not all they suffer from!

  25. I replaced one of those plastic variable manifolds on a vw jetta or cc or something for a coworker, I can attest, dorman makes a very nice, (better than german junk) replacement part with a stronger design. Still working after years. I told him to sell the car, but he's now having decent luck with it

  26. After watching Scotty, why would anybody buy a BMW or FCA??? 🤣🤣🤣🤣🤣🤣

  27. Engineered outward exploding sunroofs are one thing, but WHY were they exploding? What caused the explosion, bad engineering?

  28. I am sooo tired of all these new cars being so insanely complicated.
    It is getting to the point that when you have to bring it into service – it's not even worth fixing any more.

  29. Oh, how I long for the days of simple 'meat and potatoes' engineering.

  30. They also design jet engines to detach over the wing…not very satisfying

  31. I never wanted a sun roof but the trim I wanted forced me to get one. I wish it were only optional.

  32. We don't have sunroofs and dislike them. They leak and more junk to fix.

  33. 94 escort wagon, same problem, thought sniper was out to get me, back window blew out alot, cheaper to replace entire talegate 150$ vs 400$ for glass.

  34. Hello Scotty, my 2005 Lexus RX 330 shows check engine sign and VSC on the dash. It won’t go off even after checking my fuel cap and reseting the electrical system. What may be the issue with it?

  35. Scotty, I have an 04 Durango Limited with the 5.7 hemi. When it is cold and rainy it idles at really low rpm and chugs. Sometimes the gauge cluster even glitches. Why does it do this and what should I do?

  36. In the SF bay area I use the Toys sunroof all spring to fall. Depends where you live. Here its 70-80F 9 months of the year.

  37. If there’s one piece of advice to remember from Scotty…. he recommends you buy Dorman

  38. I have a 2010 Toyota Matrix 1.8. It currently sounds like a diesel rattle. Battery is going dead now. Battery, alternator, starter, and battery ground wire all were recently replaced a few months before the rattle. Just had oil change and added a little lucas transmission to top off the fluid level (occzsional hard shift from 3rd to 4th on interstate on ramp). Any clues?

  39. My car has a sun roof but I never use it. I forget it is even there. I have had the car for months and I have only used it 1 maybe 2 times.

  40. I hate sunroofs. My last car I ordered from the factory, had to wait 7 weeks for the car just so I wouldn’t have a sunroof.

  41. Sunroofs require more mechanical maintenance as they get older. The track gets dirty and needs to be greased. The seals can wear out after 10 years.

  42. Wait until they all end up with big batteries or hydrogen. Then you’ll see some explosions.

  43. radiation from space and our sun has increased… it is heating the inside of the earth and cooking trees and plants. all you have to do is feel anything facing the light of day regardless of the temperature..even in cool weather the surface is way hotter than it should be.

  44. Dear Scotty, I have a 1989 Ford Bronco XLT V8, it would warm up and then die. After waiting for it to cool down it would warm up and die. I replaced the coil wire, coil, and the connector that goes to the coil with the wires on the harness and now it runs good. The end. New vehicles suck, think I will keep my 30 year old truck that actually has a rear window that rolls down into the tailgate (because that's cool and new SUV's can't do that) oh, did I mention that the top comes off and it transforms into a real cool convertible for the good weather, new Suck UV's don't do that either. I say Suck UV for the new ones, mine is the only real Sport UV.

  45. Honda is now the #1 most reliable car maker in the world. Toyota lost top spot with these reports of blown sunroofs. I have heard of blown head gaskets, but never – until today – have I heard of sunroofs blowing up.

  46. Is it a Chinese glass company InDetroit Michigan making the sunroof or a clear plastic film to keep U V out ?
