Hey guys, i'm planning to get a persona std manual. Just want to know how's the car reliability? Will it have many major problems and high maintenance cost?

Thanks for your feedback. I could not listen to the YouTube clip you posted yet. But the sound I hear is nothing else other than "engine knocking" (the same sound i used to hear from my old car)
Initially they asked me to change Petrol Brand, So I did, Issue Still there.
Then I upgrade to RON97 (two different brands) NO Progress. Issue stays as it is.
Once i complained this again, they suggested to change knock sensor, so I booked an appointment after they ordered the part and got it changed as well. (It took only about 2Hrs), unfortunately, Issue still same.

I've already complained this to Proton Customer Service yesterday, I received reply today saying they will contact me again. Hopefully they will fix it this time. Even though it's fully covered by the warranty, It's just waste of my time going there and waiting for hours and hours. I'll update here about the outcome.

Hi ..

Yesterday sent my car for 2nd service at Mutiara SC .. using the FREE SERVICE from proton promotion (free oil and filter only) << this not mention before buy ..

Okay .. before i list things that i facing with my persona .. ive taken the car back but not tested yet ..

My mileage already hit 9k++ .. 1st 1k service late because SC fully booked and mileage exceed 1k almost 2k ..
this is some issue with my Persona ..

1) USB socket 12v faulty

2) USB port intermittent charging

3) power window front passenger side slow when want to roll up

4) rattling sound from backseat whenever there's passenger seating behind

5) door closing metal sound .. this issue been highlighted on 1st service .. ask them to change the rubber but dont know they change or not.

6) coolant reserved cap loose << this no sparepart .. so then KIV this 1st

7) rattling sound when low speed / climbing hill << usually i recognized this as a distributor loose sound .. usually need to adjust it and gets better but SC said the rattling is from the dashboard and the fixed it.

8) semput when up hill and low pickup << when 1st get this car no problem .. after reaching 5k only start having this.. but will try the CVT method 1st .. http://service.punchpowertrain.com/product...il1e/id/79.html

Previous issue .. SC Mutiara scratched my skirting and the promised will touch up but due to no time and i need to use the car until now not send for paint job .. they want to keep the car for 2 days for a little touch up scratch but ..

when i sent the car to SC i noticed something .. the petrol cover (metal) on the side got minor scratch .. at 1st i thought maybe my fault when i fuel petrol maybe i accidently scratch that part with nozzle .. but when look closely it is imposiible because the scratch is from inside .. when SC checked it is because the metal cover when open sometimes touches the body.. the said will re-adjust it and i complain again then how about this scratches .. the Mutiara SC Supervisor inform me when i want to sent the car for skirting touch up they will fix that also ..

Conclusion .. most of the issue is minor issue that can be solve max 1 hour but due to SC maybe lack of staff they cant and request for 1 day ..
This is my personal experienced with Proton Persona 2017 ..

My MT so far so good, no big issue, just some minor rattling, stop lamp switch, aircond odor that has been solved and now left with wind noise.

FC is 14-15km/l 70% city 30% highway... not involved in jam, just traffic lights.

MT will be cheaper to maintain when changing gear oil compared to CVT, reliability MT win too.

Since the Persona still new, couldn't tell about the reliability compared to other car, but since most parts is from Iriz, most I see from their thread is stop switch lamp malfunction only.

That's one hella long list of issues you face with SC... by the way how's your FC? The new owner here many complaint about high FC for CVT

Talking about this Pinging sound, last time I thought is my illusion or Radio... the sound was very light... but today I try again during uphill, the pinging sound doesn't appear

For your mum Saga Aeroback, the pinging can be solved be retarding the distributors... can ask those experienced foreman to help. Its just loosen up the screw at the distributor and turn it I think towards the engine? If unsure better let the foreman do it

My mum saga aeroback pinging is solved and yes due to distributor.

But this new persona/saga vvt does not have a distributor so the problem is somewhere else. I have a strong gut feeling it's the exhaust system as when my engine is cold, performance is super snappy and no pinging whatsoever. Response is amazing.

But when temp gets hot/operating temperature, car feels dragged. And pinging occurs more often.


Also regarding you changing the stop lamp switch. May I know where you did it and whom I can refer too?

Another issue I'm facing is that when air con compressor kicks in. You can really feel it's load on the engine by cutting 500rpm. I'm in gear 3 and I can still feels it's drag.

The stop lamp switch I change last year, actually I just told him the engine underpower and sometimes clutch already cannot crank engine, then so ngam all these issue is caused by the stop lamp switch...

About air con kick in, when idling you turn on air cond u can see RPM drop about 300, but when driving, I can feel a very slight pull back less than half second and the car rev it back to where it was before. Try this on 1st gear its more obvious to tell.

The heavy compressor is where we thank them for lesser sweat in hot day unlike my Myvi

with 2.30/l .. i can get 80-100km per rm17 of fuel .. think thats around 7.2l/100km .. with 70 city/30 highway
cant compare to bezza because persona is a heavy car and 1.6 somemore .. it depends on stail of ur driving ..
i always target eco light be on (dont make a diff or not, just made me feel better hahaha) ..

as u can see on my signature im doing GRAB also with persona .. and most of my rides are inside either JAM or CITY .. calculation when doing GRAB ..
usually i filled up in this figures depending how long i want to drive ..
rm10 = around 35-50km inside city with 1-2 hours of driving non stop this including idle when waiting for passenger.
rm15 = around 50-60km inside city also with max 2-3 hours ..

all this are when doing GRAB .. (want to join GRAB PM me ok .. i give nice coaching hehehe)

If on highway .. i give 1 example .. from Damansara to Bukit Beruntung using PLUS .. exit thru Sg Buloh toll .. ive tested topup only rm10.
my fuel indicator that time showed around 90km driving and after fuel up it show around 130-140km. with RM10 and reach to destination .. the fuel indicator showed balance 115-120 .. total distance i record is 120km with rm10 starting with balance petrol inside my car .. then petrol warning flashes at 80km .. with that petrol warning i can push another 30-40km actually ..

In my observation, i think persona ecu will calculated the way of your driving .. thats why sometimes petrol warning will not be on the same number.
If on the highway .. petrol warning will start to flash when reach 80-90 sometimes, maybe it detects u on a long journey and dont want ur petrol finish before arriving to petrol station.

when in city or normal driving average is going to be 70-80km before it flashes .. this is what i observe lah ..

anyway it depends on the stail of driving ..

this is what i told the staff at the SC counter .. dont know they understand or not .. if normal workshop of course they know ..
because SC we cant afford to wait and speak with the pomen .. will test my car tomorrow either the problem solve or not ..
SC inform not because of the distributor but rattling inside the dashboard ..

I don't think our campro vvt engine is utilizing distributors anymore as it is fuel injected. Distributors is for those carbureted engines.

I may be wrong though.

i suspect that also but the sound is like that haha

Actually the pinging noise for old car is not distributor problem... its the timing not properly tuned..

Ya, modern car not using distributor anymore

what timing bro .. so i can tell SC .. penat la ulang alik hahaha!

Your fc improves as your mileage grows?

What I mean is old car foreman can tune the engine timing from the distributors, but modern cars like ours don't have such thing... so don't know what are the issues here...

To explain to the SC you can just tell the sounds is like old car like Iswara engine timing is not properly tuned, so when you apply more gas especially going up hill the pinging sound will appear.

yupe .. notice the diff before and after 1st serv .. i think the oil they put not so good .. huhu!
lucky its free service .. if not i already use torco hahaha!

How often do you pump petrol when doing Grab?

depends on the hours and trip .. easier if ur reset trip before start ..

how much you paid for 2nd service?
plan to do at 11k
