yea its like something knocking like metal sound from engine bay.. but its actually from driver side door. i think lack of soundproof or maybe when u figure out. u can tell us the solution..

i install the first day i got the car. so far no problen wth SC.

Theoritically, anything that is 'plug and play' wont void ur warranty, this is what the SC told me.

I wonder which bars u guys installed into your ride. Mind to share?

I heard it sourced from engine bay... Still figuring out the solution.

what is the ultra racing bar for?

please update us when u found out how to solve it, Many Thanks!

"Engine bay metal knocking sound"..
"weird sound coming from engine bay infront of driver"..
"Sound tat hearing when speed overbump"..
I having the exactly same problem liked u guys.. But only till tis early morning after went to SC.. It's cause from the loosen part of lower arm.. After tighthen up and put some lubricant.. The problem solve?!.. And YES the irritating sound gone so far i drove/tested until jz now.. Tis was my experience with the famous problem u guys having here.. Happy Motoring everyone ))

Bars that bolted on car chassis to increase body rigidity and reduces rolling.


Im looking for it as well.

Loosen part of lower arm? That sounds serious. Let me called up and book for this problem rectification.

Shall update once i get it done. Thanks for the solution sharing.

mm.. if the lubricant dry up will the sound comes again? what spec u driving?

lol and the milo tin close door sound..........

pls update us more about ur car @@
if confirm solve gotta bang their table hard when 2nd service,
they told me already tighten everything at 1st service but didn't solve at all...

I walked and talked to the technician which fixed my car.. Saw he tighten here and there.. Most important part is lower arm part.. Which is the side of lower arm.. Need to turn max the steering clockwise&anti-clockwise to tighthen the nut beside and to put some lubricate.. At 1st, it remind me of 1forumer/owner here mentioned they already tighten all the part.. But at the end same story.. Problem still exist.. This made me curious it's reli can settle the problem.. But it reli did !!! So,u need to double confirm with the SC.. It's reli all part been tighten up.. Bcoz some technician only tigthen the visible part.. Maybe they lazy??? Or lack of experience???

BTW, Im driving the latest J-Spec auto ))
I got my car on new year's eve...

thanks for sharing~

the milo tin sound of door panel can be rectify by applying dampening. I think it cost around RM600+ for 4 doors, 3 layers. If better, get 5 layers for RM800+.

I didn't do it since my main concern was tyre noise and hollow resonance in the cabin; therefore only did rear boot and wheel arches.

I think no need to wait until 2nd service at 5k. I'm currently at 2.3k ODO, and plan to send in next week to rectify the lower arm knocking sound, loud hissing noise from steering upon turning, and the bloody loose brake pedal rod.

lets see how.

eager to wait for the updates... i think this week u can send straight away to update us when tightening lower arm and put some lubricant will really solve the problem or not..

pls do update us too which screw to tighten if possible and take pictures too... so that i can tell my sc do exact things..

tried to call SC Balakong just to book a checking for tmrw, they said weekend only do normal service and no diagnostic provided. KNS!

week days no need to work meh.

so tomorrow you can update us already .. if tightening lower arm can solve the prob, i wan thanks u many thanks!!

im not going in tmrw coz they only do normal service on weekend.

For this kind of checking, its only available during weekdays.

so u change booking to weekdays? thats mean next week?

no need to work meh, so haven't book any timing yet.

thanks for sharing

finger crossed for ur good news, if boleh pls take photo of the screw of main cause as fellow mention
will just find outsider help me tighten instead of wasting time back to SC lol

Thanks for sharing. btw when you booked the car. i'm waiting for mine.
