so far here are the rattling sound detected and solved...DIY though.....SC couldn't solve my problem fully
knee airbag on driver side rattles on semi rough roads at around 20kmh to 30kmh speed. quite annoying and appears almost all the time
found root cause:
1. the knee airbag front plastic cover is not a perfect fit with some loose gaps.
2. some of the metal frame esp with nuts and bolts are not tighten up (though it is not loose)
3. vibration from the thin metal frame
what SC did: tighten up all the nuts, rechecked the cables and used some cable tie to secure the cables....reduced some rattling but not entirely
what I did: had some left overs of Dynamat sound proofing material (the ones with bitumen and aluminium sheet for vibration grounding).
sticked some sound proofing material on the thin metal bars below the steering, the back knee airbag frame (wont effect the airbag).
added a 8mm insuflex on the thin metal to absorb any further vibration
done...perfectly no rattling sound..tested few days on few roads near my house where the road is not even and quite rough surface. various speeds tested...so far ok
2 more minor defects detected
rear bumper left side just below the tail lamp, the clip doesn't clip properly resulting in minor bumper alignment.
driver seat lumbar support can feel the lumbar mechanism protruding
trying to find time to get to SC to have both defects fixed
other than that, no seat rattling issue and other stuffs for now
just done first tank and now on second tank....did 770km on 52liters...that's 14.8km/liter....which is quite good...no particular driving pattern...just start car and drive per normal with occasional variable speeds
had couple of times traffic jam in between
the warning light start to pop up when i still have 15 liters of petrol....its like when i finished first 3 quarters of the tank, the low fuel light came out....
GPS interface not very good and troublesome....i still prefer waze....also because of traffic updates and smart routes
the absorbers are too soft for me....full load passengers, middle section car scratch some bumps.....
after first service....so far so good....SC did alignment and balancing for me though i was sceptical in the first place...but it turned out fine...they did a 32PSI pressure for 4 tyres....felt it was abit too soft....had pump it back to 36 psi front and 34psi rear
I am experiencing some rattling issues whenever the road surface im travelling on is slightly rougher. The rattling sometimes is loud even when the radio is on and sometimes not noticable even with the radio off.
As for the lumbar support, i am too having the squeeky noise when lumbar is fully inflated.
