Definitely report it to the NHTSA because major corporations wont do anything until they are pretty much forced to.

 

Sorry but did the engineers in Japan or where ever they designed the TC think we gonna drive these cars in climates where the temp is always constant ? Im sure they didnt think that so that leads me to believe they didnt put much thought into this . I read in another post where a member stated that he felt Toyota was ridding off their previous reputation of well built cars and was pumping out lower (than their standard) vehicles . In a way I cant help but think the guy was correct in this statment . I have rode in early 90s toyotas MR2's , Camrys , Celicas . YES these vehicles had issues and had rattles , they ALSO HAD 80+ thousand miles or more on them , not 2 - 6 thousand miles on them . Over all with this car , this sunroof issue has me on edge , and the rattling hatch . Over all the rest of the car is fine . Personally I have a feelin Toyota is gonna have to do something about these sunroofs . My dealership here in Jacksonville had one guy come in cuz his wind deflector litterally flew off the car going down the highway , as in detacted itself . Again I know there are some out there saying we complain to much about the vehicle . Well if I was gonna buy something that sounded like it had 80 thousand miles on it , I would have bought a used car not a NEW car . Ok my rant is over LOL

 

Dark colored cars get hotter in the sun. Wonder if that makes a difference...

 

its actually my girlfriends car, sorry ;)

the car was bought from Bell Toyota/Scion about 2 months ago.. it has 1700 miles on it. We live closer to Right Toyota in Scottsdale, so we decided to try our luck there first. The first guy was a regular Toyota service rep..he said "oh thats rock damage.." haha, of course.. he calls down a Scion service guy and he looks at it, listens to the story..we reassure him it was NOT BEING DRIVEN.. he comes back a few minutes later and says "we will goodwill the glass for you". He tells me they have replaced 8 front deflecters from rock breaks.. *yikes*

It was nice of them to do this "one time goodwill", though I do believe it should have been a simple warranty claim.

Moral of the story..EVERYONE CARRY $0 GLASS COVERAGE

 

I do believe that it should be warranty work. Maybe he was just saying that for whatever reason (sour grapes) but defects are warranty issues.

 

Its weird too..because on my Nissan and BMW, I've had rocks hit the sunroof a few times..doesnt seem the phase it.

You would think on a car with an ALL GLASS top..it would be the best glass available!

If anything..if and when the NHTSA approves that TSB claim, they will probably replace it with dual pane glass versus tempered safety glass.. what do you think?

The sunroof is another story, I dont know of any cars that have dual pane glass for that

 

wow. this seems to be a common problem along with the sunroof itself breaking. there's also been a lot of people who have had to get their windshields replaced because they broke as a result of small impacts. anyone else here get the feeling that scion somehow used "cheap" glass to put on the tc and maybe all scions? i know cheap glass might sound weird because all car glass is supposed to be the same, or at least all toyota glass should be the same, which would include scion, but these glass breaking issues are just a bit too many to seem like coincidences to me.

also, maybe scion used light, thin, not very hefty glass for the sunroofs and the spoilers in order to keep the car from weighing too much. it still weighs a lot but maybe more impact resistant glass would have made it weigh even more so they decided to use less impact resistant glass. this particular situation wasn't an impact situation, but you know what i mean.

 

that last line is classic

 

i wonder if the c230 kompressor has had problems with its glass. the tC is more of a copy of that car in the design.

 

Actually, I got to thinking and the rapid cool down doesn't really hold water. Why doesn't your windshield or windows break if that's the case? The glass just needs to be thicker.

 

because there's a difference between tempered glass and safety glass.

Your windshield is made of safety glass, and has a layer of material in the middle of it made to keep it from shattering and injuring the occupants of the vehicle. The glass on your windows (and obviously, the roof) is tempered glass, which is just made to withstand certain amounts of stress, heat, cold, and impact. This glass, however, shatters when it breaks. I actually have to admit that I'm somewhat surprised the roof isn't made of safety glass, given the fact that it too can shatter and injure the occupants.

 

DUDE hottie in pink, anyway sorry about the car, glad mine has not experienced any of these issues.....*knocks on wood*

 

i hope theres a recall and all the glass gets replaced with polycarbonate

 

THAT SUCKS... somebody should make a carbon fiber one

 

The problem with the glass panels could be improper tempering. Improper tempering would cause stress to be trapped within the panel making them particularly prone to easy breakage if any additional stress is exerted on it (big temperature fluctuations or wind loads). This happens a lot out there with other car models and brands. It's a quality control issue with their suppliers which is most likely outside of the Toyota system (Contractors). They should be able to tack down and fix the problem on later production units. Good suggestion about making it out of fiberglass or carbon fiber instead though! It's an opaque panel anyway. But then, people might wish that they had the early series TCs with the GENUINE, ALL GLASS ROOF!

ok been foolin around with my sunroof seeing if anything can be done concerning creaking and poppin noises . I attached two pieces of material (the soft stuff used for Velcro NOT THE HARD PLASTIC STUFF THAT ACTUALLY LOCKS VELCO) to the small feet that slide up the stilts of the wind deflector . They did reduce the overall creakin and poppin noise some but not all of it . Before all bumps in the road would make the sunroof pop and make noises when it was tilted up . Now , you have to hit a rather good piece of rough road to make it cause a noise . I originally tried using the felt pads you put on the legs of chairs to protect hardwood floors . That canceled all noises from teh sunroof (Good thing) the downside was , the felt pads were to thick and caused the sunroof to create to much wind noise when drive at highway speeds (sounded like you were in a 747 ) . The thinner pads have no wind noise but like I said still allow it to rattle to a certain extent . My theory on the sunroof rattle and noises are . The sunroof when tilted up doesnt have enough pressure on the front of its frame to make the pivit . It has play so when you hit bumps the sunroof moves which causes it to move freely and lead to more rattles . The felt makes the pivit (the feet that slide on the stilts) tighter , which leads to less movement and fewer noises. Like previously discussed this might and might not solve your current prob since most these noises are different in causes and so forth but hey wont hurt to try it.Also if you dont know what your doing and you screw it up it aint my fault LOL
