Major problems with my My 2009 Persona (A).
The day i got the car, its got this annoying engine pinging noises. It was very very minor at the beginning. Things got worse as the KM builds up. The engine knocks more often and even knocks occasionally at 2k rpm while cruising. It is more obvious during very hot humid days.
Finally, on 10 June 2011 i had my ignition timing retarded from stock "step 1" down to "step 3" to reduce my engine pinging noise. Now its 99% gone but then the car feels laggy a little and less responsive as before. Gonna have it reset again this week to "step 2" timing setting.
FYI, campro ECU got 4 steps of settings for the ignition timing.
FYI, Proton's SC outlets do not have the fixed standard. Some told me "Campro engine memang macam itu....tak boleh buat apa-apa", "cuba you pakai ron97....confirm tidak akan pinging lagi"..........things like that. what the f*** man. damn pissed. luckily i went to one of the SC and they know what and how to deal with the problem.
PROTON AFTER SALES SERVICE SUCKS BIG TIME.

Source? You experience it with your old Proton? Did you try latest Proton's cars before? Why my Neo CPS one year already, and it performance and fuel consumption getting better? NO problem at all?
I assume you say Japan's cars good? My dad just used RM8k repaired 1.8 FD2. It depends how you maintain the car. Proton sold many units. If the owner gets problem, sure will "notify worldwide", people who can afford Honda accord or civic, usually won't go online so often as they are busy running business(My point of view). So if got problem, they won't post on website "oh my car is suffering....".. If you get it. Sorry for my broken english

*every car is almost the same. But still maybe Proton is lower grade a bit. "What you pay is what you get". Example Civic is RM13xk, Gen2 is RM5xk.. Is huge different

yes very true.
have you seen Toyota's service centre complain board (a white board with owner's car plate listed and problems need to solve by Toyota technicians) located in their workshop... its a long list. So there u have it........
Proton = problems = shit quality..... yea that was past tense. The introduction of the Persona model was the turning point for Proton to move out of their very poor QC era and move on to be better and better.
It is far far better quality now. I would say, Perodua's quality is far worst than Proton now. Believe???? I replaced my 3 1/2 years MyVi due to lots of problems, crappy build, rattling body, very poor suspension, very poor handling and very very very very poor automatic transmission tuning. AND NO..... this is not a one of a kind case. It is the most common complain for MyVi owners. It is listed and complained a lot in two very active forums.
