Ok so the car had a few issues:

My Questions for the dealership:

1. extremely annoying rattle noise around 2-2.5k rpm and during acceleration coming from the left side of the steering wheel above my knee - I asked them to check for the bearings since the noise came there the same day i picked up the car after they installed the S/C

2. S/C itself makes extremely weird noise (no i'm not talkin bout the whistiln nor the purring) - told them none of my S/C friends ever had this much of a noise and this type of noise so i told the dealership to check the bearings again

3. Rear squeakin noise over the slightest bumps/dips even if taken at very low speed (5mph) - told them I had checked the springs/shocks and it wasn't that so that it prob was the rear sway bar bushings needing re-lubing

So I took the car at the dealership and this is what they told me:

The answers I was given:

1. "the noise could have been caused when someone removed your dash to put in blue lights" - when i told them that the noise was there before i changed the LEDs he basically told me I was lying and that they would take the dash apart and see if the rattle is factory caused or LED change caused...

2. "no two S/C make the same noise so maybe what yr friends have is not what yr S/C has" - again, I don't believe the S/C is ok because the noise was not there the first month or two but came later on; but they assured me they checked everything there was to check and that the S/C was good to go

3. I was correct, the bushing were completly dry so they lubed it.




Now. I'm def. not convinced about the first two "solutions/answers" I was given. Is there something I can do or I just will have to wait and see if the S/C blows up

 

The dash rattle around 2K rpms seems to be a normal thing. Does it sound like its coming from the driver side vent? Ive seen countless people experience the same rattle problem after going s/c'd...I noticed it immediately after I got mine installed

 

I had it on mine as well. Took it in and after a full day of tearing my dash apart, they found that a clip on the cover over the heater core was broke, and when the engine/supercharger hit that right frequency, the cover would sit there and rattle, and the noise vibrated right up the vent tube and out the driver's side vent. They replaced the cover under warranty and that rattle was gone for good. Something to check out... And I'd never done anything under the dash so it HAS to have come from Toyota with the clip broken.

 

yup right above my left knee close to where the mirror controls are.
so I just gotta suck up the noise?
is it more noticeable also when the engine/car is cold?
So should I tell them not to open the dash or should I let them anyway?


They came back to me saying "when we install superchargers we don't open the dash "

I know that, thnx. But obviously, since i'm not alone; it does have to do with the S/C

 

Thanks man. I think I'll give them a call then tell them what to look for.

 

No problem. When my service adviser told me that this is what they found, I was more than a little skeptical. But they replaced the cover and the rattle was gone forever - well, for as long as I had the tC.

 

nice, ill wait till they call me - if they say it's factory related and that they will fix it free of charge good. if they come back at me and give me the BS answer that it's the LED gauges that caused it then i will tell them to look into what you said.

 

I am betting your rattle is something like what was just mentioned Claudia. An SC or even a CAI changes the noises that are present in the engine compartment and drivers compartment, so it may just be creating just the right vibration now to allow you to hear the rattle.

If it were me, I would make them eat thier words about the led swap when I took the bezel and cluster out (in less than 3 min) and asked them to show me what part of that was making the rattle. Hell, take it out and see if the rattle is still there. If it is, go have them drive it. You disturb nothing in the dash but the cluster and bezel when doing an led swap.

The sway is an easy one, sounds like they took care of that. Mine actually started creaking a bit this winter, so I need to lube it soon (havent driven the tC in weeks sinc the roads are covered with salt/snow a lot lately).

On the SC, make them document what they told you on the ticket. If it fails after that, take the ticket back as proof you brought it in under warranty with a complaint they could not fix. Even if it is out of warranty by then, they will have to fix it, or try to come up with some bs to say it wasnt the same issue

 

Thanx for the input Dave. Yup I'll wait for their call. If they give me the led bs I'll say that I'll come over when they are open and will take it apart to show that ALSO I didn't have anything to do with the dash when installin LEDs

I will def. check that they document everything on the invoice about the S/C and will keep those receipts close to me lol. I fear I might have to pull "my sister/lawyer will take a look at the papers" card again

 

^^ its better than the "I will sit here and throw a s#it fit in the sales lobby in front of all your customers" card :D

1. thats absolutely right. THey have no idea what could be causing the dash rattle. If its OBVIOUS that your dash has been disassembled and/or altered, they have no impetus to diagnose the noise.

imo, its probably related to whatever was done when your dash was taken apart. (thats why i don't waste time doing chintzy little LED mods, more trouble than they're worth).

IMO- its probably cold weather related......

2. theres nothing u can do, unless you are a qualified tech to diagnose it yourself. THey say your S/C is fine. Get that in writing and just drive your car. Try to ignore the "Scion Ticks". if the s/c goes out, then make sure you provide the documentation and it should be covered.

while magnusson-moss is SUPPOSED to be your friend, its such a pita to get to a point where you can actually use that (ie. court) that your basically at the will of the dealer's service manager.

its highly unlikely that the 2500rpm rattle is coming from within the engine, which leads us to that its probably engine vibrations causing rattling, something contacting something else and tapping on it.

FYI--- these are the breaks of the game when you choose to mod your car. Its not all fun and games like you see in Fast & Furious.

 

thankfully the sis will be happy with a simple LUSH product =D

What you are saying makes absolutely no sense! All Go away Forpinks!

 

It has nothing to do with the LED because the noise/rattle was there for months before I ever touched the gauge cluster. So yup must be other vibrations; something hitting something.


Never watched them =D

 

i would say take it to another dealer and get a second opinion

 

i was just there today, they were saying they were looking into whether or not your tc has the newer bracket or that the older s/c kits didn't have and if replacing that could make a difference etc.

but i wish you luck claudia. i'll have to get mine installed so that we can compare, both the sound of our tc's, and how well they drive. lol.

 

it should be the newer version S/C with the newer bracket (that's what the seller told me) but i'm not 100% sure

 

I was hearing a strange noise from behind the dash as well, but I am now convinced that it is the BPV, I guess i just have to get used to it.

 

so, let me get this straight.... your dash had a rattle, but you still took apart the dash to install your LED's anyway??

 

just soo you know, the TRD supercharger has some flaws.....first flaw: the shaft in the middle has nothing to hold up since it's to long...and has nothing to hold it..so it vibrates pretty hard....and there's a bearing in the before and at the end of that shaft before the pulley.....what u need to do is to weld something around it to the bolt/nut on the exhaust manifold to hold it up so it won't make that noise again.. i have that same noise. ANyhow, it has nothing to support that's why it's making that noise.
