The manager and supervisor seems ok. But the mechanics there is no different than the other. I told 1 of the mechanics that my front passenger door is not align properly with the door behind and it also sounds weird when the door is closed(Saga BLM door closing sound), I also told him that engine vibration is quite serious. Then, he replied me, semua kereta pun macam tu. Move along to the dashboard rattling issue, and some foam came out, he juz use a screw driver to poke the foam in and said it's done.
Water leaks through the door frame and dripped in driver's cabin. His solution is just screw everything tighter at the door hinges and spray water at the top part of the door and found no watermarks and said it's fixed, and now it's still leaks water in. Driver's door rattling noise is even worse than previous time!
I did go through all the defects, 1 by 1 with the manager there, and I decided to leave my car there, also recommended by the manager herself, but it seems that all those defects are still here and nothing is fixed! NOTHING! She did said that they won't be removing the whole dashboard bcoz it's too risky or whatever whatnot, but the thing is, all the sounds is from the inside! What if a few screws are not tighten properly? Steel to steel part is not welded correctly? Or the plastic didn't fit properly? Sometimes I wonder, will those 6 airbags will work properly? Or some loose screw inside will fly out after the airbags deployed? Trust me, if you told this to some irresponsible Proton Mechanics, they will just tell you that Japanese cars and continental cars also got problem larhh.
About the annoying rattling sound coming from the dashboard, I did try to add some foam all around the dashboard area, including the very poor interior plastic build at A pillar, it's still making a lot of noise. Surely it is not based by the end of the dashboard is knocking on the windscreen that makes a lot of noise.
Sad to say that, it's really disappointing.
For rattling issue especially inside of interior (i.e: inside door panel, dashboard related) is better to send to branches because dealer will not entertain those as they will be responsible and bear for the damages if any negative issues arise (unable to claim from official Proton). That is why they are not willing to take the risk. For normal services, Senaxis will be an ideal place.
I went to CoE but the rattling doesn't completely fixed, but it gets better than before and only appears once in awhile. What foam are you using? Have you tried using D-door sound proof to slot into those gap and see whether it helps.
