I have rattling sound from from somewhere in front but not dashboard. Complaint to SC and they arranged a test drive, the tech guy also managed to hear it so in the end they did was tighten parts. After that no problem

But nowadays i notice a squishy sound from the trunk area.

i have the same issue, when go to service center, cant simulate the rattling sound, my case is intermittent, but early morning when the engine notyet heat up, sure got the rattling sound front the dashboard.

1.5 TC or 1.8?

Which SC you went? Daylight robbery by SC.. 40k service only change part below.. Cost you around 400 only

If the aircond evaporator was changed, then the price for it is actually cheap. This is P1 / P2 parts pricing.

Wheel alignment maybe due, the price is more or less SC con job standard price la.

Engine oil maybe is the red bottle one. That is why went to 0w-30. But i think still pricey. I remember "last time" the price was just a little higher than the discounted price even before discount.

It is actually something that purportedly works. But, maybe not on a 2 year old car.

A bit unnecessary in my opinion if you replace the aircond filters pretty frequently or on time. Maybe when your aircond got some rancid smells or something is when you might want to consider doing that.

The canister is actually pretty much cheaper to buy outside anyways if you decided to DIY it. Unless they have special equipment to do it, that price is pretty steep.
