I've done my 10k servicing and with addition to that, I've provided below list of complain for them to rectify :
1. Rattling on left door/dashboard
2. Rear bumper not aligned
3. Faint knocking sound when turning air-cond in the morning
4. Weird sound when steering to the left
5. Dropped clipped on underside of left front fender
At the end of the day...
1. Rattling on left door/dashboard
- they've missed this out completely!!!
2. Rear bumper not aligned
- they claim they're not famillar with 408 mounting/installation and they have to send to 3rd party bodyshop to rectify
3. Faint knocking sound when turning air-cond in the morning
- they claim that it's normal
4. Weird sound when steering to the left
- they said something about the hydraulic hose and will require one whole day to fix
5. Dropped clipped on underside of left front fender
- FIXED!
After few days, new rattling sound emerged from somewhere near the rear seat or bonnet and it's VERY OBVIOUS! However, when there's someone sitting on the rear passenger seat or in the morning or when it's raining, the sound isn't there. So then I've set a new appointment and complain on item 1 - 3.
At the end of the day...
1. Rattling on left door/dashboard/rear seat/rear bonnet
- They inject some foam in the dashboard for soundproofing and it seems to work. With addition to that, it improves sound insulation coming from the front tyres as well. The one attended my car claim that Pug CBU cars has paddings on their dashboard but not 408 sinc it's CKD. So maybe you guys can complain on dashboard rattling and you'll get better sound proofing. But the faint rattling on the left door is still there.
- They've tightened loose screw on the rear seat and claim that there're no rattling after that. But guessed what, after only few meters out of the SC, the rattling appears! Makes me wonder whether they've tested it throughly or not.
2. Rear bumper not aligned
- They've dismantled and clipped the bumper back on its mounting but it's still the same. They say it might have to be sent to 3rd party bodywork shop to be rectififed.
3. Faint knocking sound when turning air-cond in the morning
- Again, 'it's normal'
4. Weird sound when steering to the left
- I didn't include this as part of the complain but mention it to the attending guy. He said they receive few complain on 408NA regarding this issue and it seems that the solution is to upgrade the coupling. But there're no complain from 408T yet.
So, I shall set another appointment to resolve issue no. 1 (rattling on rear seat/bonnet), 2 and 4. But I wonder if I could go for another SC instead of going back go Glenmarie SC? Or maybe it's time to call my SA and ask him to push SC to resolve these issues?

I'm experiencing almost the list of problems as yours with my 408T. Kind of annoying with all those tiny squeaky and rattling sound while driving.
Tomorrow will be my 3rd time of appointment to fix the problem in Balakong SC. I'll send my car to Glenmarie SC if the the problem still persist.
