I got my car on last year Oct. Less than 1 month started had so many sound come from dashboard. Twice go to proton authorised centre in Salak Tinggi one time in cheras and the last one Proton Edar Juru. Proton Edar Juru technician inform this is known issue from Iriz and since New Persona had the same design so the issue from Iriz will be same to new persona. Since i need to go back KL that time i couldnt leave my car at Juru centre and they advise to bring to COSE to install IPKIT. My car ended up leave at COSE for almost 2 weeks and its all fix. No more sound however the aircond keep blowing to my leg even i had turn off that option.

Bring to Proton Authorised Salak Tinggi they found something stuck below there (which means COSE Technician didnt install IPKIT properly). 4 weeks later the sound from dashboard come back again and i had no more energy to send to service center so i decided to ignore until it gone worst the sound come from the back door.

Bring to Salak Tinggi again they try to tighten all the screw however its not fix. And again i just ignore all the sound. And now new sound come from back. Could say my whole car is super noisy shaking sound. Since i am in penang i send to Proton Edar Juru to check again. Technician had fix few minor sound however still got certain sound they couldnt fix. They had rectify the sound was cause by unproperly install of IPKIT.

I had really stuck on this proton car.

My Iriz got dashboard creaking sound too, haven't sent to fix yet, but since machiem not critical, I've been procrastinating it 

Well, try talk the matter with the CEO, he seems nice, humble and hardworking guy. I happen to meet him when I service at COSE, never knew who he was until he gave the name card, wow CEO Proton Edar.
