problem with creaking sound at back of car

[mazdas3sporte]

ok so recently ( since 2-3 days ago) I've been noticeing that when i break something in the back of the car feels completly strange, u know when u have something in your truck and when u brake it slides forward a tiny bit, kind of like that, so i turn off the music and i keep breaking after reaching 20kms and everytime i hear it... i have no clue what it is, i checked my spare tire and that was secure in its place with everything else, i even checked the back bumber thinkin maybe some how that was lose? even though its a brand new car with no accdidents what so ever... does anyone have any clue what this sound is and how i can fix it, its a new sound so iam not sure what it could be.... i also have trouble with my engine stalling on start up every few days and this is with the needle on the fuel meter full and beyond the F mark so its not when the cars dry on gas, note the car is brand new with 2040 one owner kms on it.....

any help at all would be greatly appreciated.

check your rear sways? my rear endlinks have broken twice and the bolt has come loose once already...did you upgrade sways on your car or is it completely stock? It's a very annoying problem for me so far and I've only had the car for a year.

[cash_money]

i give up trying to fix all the creaks/noises on this car...

every day there is a new day...if u wait long enough that sound will go away and something else will surface...

Doesn't hurt to check the rear sway bar. Bushing might be too tight, endlinks might be loose. But that shouldn't be heard under braking, normally a sway bar would squeak when one wheel is displaced more than the other.

the car is completly bone stock with no mods what so ever done to it, 100 % out of the factory car.... it happend when i brake or drive off but its more noticable when i break, it sounds like something is lose moving forward from the back of the car or someone is hitting u at the back of the car slowly, very strange sound, i dont even know how to describe it, iam going in on thursday to duffrein mazda so i have have some of there so called "techs" with grade 1 education look at it, last time i went they were useless but it doesent hurt to try, if that doesent work iam off to MoT

[Donutz]

Is it a clunk or creaking sound? As noted above, try checking your rsb and endlinks. If your car is parked and you push on it (either forward/backward or try to compress the suspension) does it still make the noise? Also check your lugs to see if they're all tight.

[mazdas3sporte]

yepp i checked everything that could be lose,rims , ,lug nuts, spare, jack , back bumper , gas shock absorber's, compressed the suspension , braked hard, braked light.... nothing seemed to be it , how do i check end links? its a creaking type of sound , sort of like a very dry door when u close it but loud and deep, lol i cant explain it better then that, 2moro or today i am gonna have it looked at, iam in a lecture righ now so maybe later on i'll go.

*update*, went in today at duffrin mazda, I had 1 tech drive the car around and say there was no problem, exactly what i knew i would hear, i got in the car and drove around and showed him the problem when i braked, he admiited something was wrong... they took the car and did some checking and found nothig was wrong, hes explanation to me and i quote this, i know something is wrong but we can not find what it is... now were at the 3rd time, i get in the car with the shop foreman and he realized there is a problem but maked excuses such as ur braking hard,.. now for the 4th time with the manager i go in the car and drive it and he denies it, I get out and i told them i would not take the car untill this problem was fixed... fast forward to 4:30 today... they say they pulled the wheels off and i got a paper sayin that my read rotors were warped, machined rotors and installed insulation.... I drive home and i notice that when i brake something pulsaytes, sort of like when ur abs turns on in snow... but much more quiter... also when i brake from speeds of over 40km/h the engine makes this strange sound like a jet engine shutting down...at this point i was completly pissed and i just ***in lost it, i call them and i swear and bitch at them for creating 2 more problems now.... in conclusion I strongly suggest no body go to duffren mazda... they are a bunch of incompetent idiots that just bull shit answers out of there ass.. the car has 2100 kms as of today... 32 of which they put on testing and testing , the guy tells me the rear rotors are warped because of hard braking or because of time.... the cars 6 months old wih 2100Km on it, where do u come up with answers like that? they dont kno there face from there ass these idiots.. iam gonna file a complaint with mazda of canada if the manger does not call me back and fixes this issue and iam also going to file a calim in smile claims court... srry for the essay but i just needed to get this off my chest

[condor888000]

Warped rotors should of caused an odd feeling in the brake pedal not a creaking noise. Somethings not right there.

[mazdas3sporte]

i kno... u know what the thing is now, when i brake i feel the warp... and they said they fixed a warp..... iam seriosly pissed

[condor888000]

Did they replace the rotors or turn them?

EDIT: NVM your post says machined. I wonder if they machined them incorrectly making things worse...

[mazdas3sporte]

Ok I will write exactly whay they say in the peice of paper,

1 MISC MECHANICAL

pls chk and report crunching noice from rear of vehicle when braking or first accellreation
FOUND REAR ROTORS WARPED, MACHINED ROTORS (PO214BMX 1.2H)

2 MISC MECHANICAL
PLS CHK AND REPORT TICKING FROM ENGINE WHEN ACCELERATING
INSTALLED INSULATION

if you would be able to help me and tell me what to do that would be great... iam getting no where with these idiots

[mazdas3sporte]

by machined iam guessing they dident replace it? can anyone tell me what is machined?

[Donutz]

Essentially they've taken material off of the face of the rotor (I.e., they've ground it down to make the rotor face flat). The rotor should be completely flat after machining though.

One thing to note, and someone correct me if I'm wrong, but you may need to bed your brakes now that the rotors have been machined. Meaning you need to transfer pad material onto the face of your rotor.

Are you sure the sound comes from the engine? Is it possible that it's your brakes making the noise?

[mazdas3sporte]

i have no clue but now when iam braking there is a slight pulsing effect under my foot , sort of like abs in winter but as i said its very light, u can still notice it though, i know my car , so if anything is diffrent i will be able to point it out straight away, should they have replaced the rotor instead of machining it? cause from what i read online u only need to machine the rotor if ur changing the pads ... correct me if iam wrong,

another thing the idiots told me is that my rotors were warped maybe because i braked very hard and then drove into a puddle?? she said they would heat up and then cool down fast causing a warp, which makes sense if it were tru but i dont brake like that in a mazda... that just sounds so stupid

[Donutz]

Yeah, I'm not sure about the stopping hard and then driving through a puddle; sounds fishy to me =/ Not to say it couldn't happen, but it sounds far fetched.

It is possible to get your rotors machined without changing pads though. My buddy had a problem with the rotors on his TSX. Acura machined them twice, then finally opted to replace the under warranty.

I would try bedding the brakes to see if that helps. If not, back to the dealership for more investigation. You may want to consider going to see Jimmy at Street Performance to see if he can figure it out.

Good luck.

update* I was driving in 401 yesterday taking the exit to leslie, when I braked from 100 to 50, the whole car started vibrating... the brakes were seriously damaged after what they did to it..... I go back today at 2:45 and they replaced my back rotors and pads wtih new ones, the problem with the brakes pulsating and vibrating is fixed now, my initial problem still exists, they were able to find out that there is a problem when u brake, somethin in the back of the car thumps. after waiting for more then an hour and having them call mazda of canada they were not able to find out how to fix the problem, unfortunetly I am going in on tuesday once again to let them take the springs/shocks off and see what is going on with it.. they basically have to take the car apart to find out what is wrong with it... on the plus side i am getting a free 24,000 check up thing thats supposed to cost 180 dollars... better then nothing i guess... the manager on many times admiited that it was there fault my brakes were messed up after they quote "machined it"....


for any future problems I will consult another dealer, for oil changes and what not they seem to be some what capable, but for serious things i would not suggest anybody to go there, iam already up to my neck with them, at this point iam only dealin with them for this issue because they have a file on everything they did, but for new things that might come up in the future relalting to a "defect "
I will post updates as I get it.

P.S as i know many of u have this ticking diseal type sound coming from the engine, they put some insulation somewhere and it seemed to have made the ticking diseal sound less, by no means is it a fix its just a cover up, after this whole issue is fixed iam gonna open a new file with another dealer for the ticking

another update,

I looked at the rear rotors which they day they are replaced, they dont look smooth at all , it had a criss cross pattern on it, could this be result of machining? does this mean that there rotors are not new? i have 2 other cars in my family and all have circular motion that goes around the rotor not criss crossed like this at all? I might be just paranoid but something just doesent seem right, notice the edges on the second pic where there is some fading? this cant be normal for a new rotor? I took these pics in High Res so u can see what iam talking about,

[Donutz]

These pics aren't as close up as yours, but they do show a similar pattern; not the same but similar. (please ignore my dirty rims)

[baymoe]

The rotors appears to be new and not machined. Once the rotors are more worn down, it'll be smoothe. You're being paranoid... lol

[mazdas3sporte]

ye urs is pretty much the same pattern, so what you are sayin is that they are new ? the reason i asked was not just cause of the criss crosses, it was because if u look at the edges there is like some deep scratches in the rotor, I have edited with paint so you know what Iam talking about.

[Flagrum_3]

The rotors in your pics look brand new, the lines you see are just from them going over the rotors with either emery cloth/sandpaper to clean the surface and to allow the pads to grab more uniformly for initial break-in....it's common!

As for the clunking at the back; Have they checked the calipers or parking brake mehanisms?....I had the same situation with my brakes before I switched to aftermarkets but the problem was the calipers, as for the parking brake it sometimes didn't release properly until I moved the car and it would release with a clunk.

[mazdas3sporte]

iam not sure if they have checked this but I will check with them on tuesday and see if they have done this or not, he thinks it might be problem with the shock springs but i dont think so because when i go over bumps there is no sound what so ever, its just under normal breaking. no problem with the parkin brake at all, iam really paranoid unfortunetly so if anything is up with my car i can tell right away that its not a normal sound, like after i got the car back, this is after they had replaced the rotors , when i steer now there is a slight sqeeking sound coming from the steering or tires , the sound u get when your turning on a stone/marble parking or paved way, i dont think there is anything wrong with this but i know that it for sure wasent there before they changed the rotors

*Update for anyone experiencing the back noise*
Just got a call few minuites ago about the creaking at the back of the car, the service manager informed me that they had droven the car as far as misisuga srry for spellin, and had found nothing wrong anywhere in the car, he informed me that he had driven the car for 58Km's with a tech from mazda of canada and 3 other people and no body could find what was wrong with the car , in their words they checked everything and nothing was found wrong or lose, he informed me the car had a 5 year warranty and if the problem got worse to bring it back again and they would give me another rental to see if they could find the problem, most likely iam gonna be going back there again , i aint giving up ne time soon, about the engine ticking issue they said they had fixed this with a part , i cant confirm on deny this as i have not picked up the car, i will pick up the car 2moro and will make a seperate new thread about that stating if the fix was real or not, which i doubt again,
