bro,i am also driving proton persona iafm auto old version,the problem with the old batch persona as below -
1.steering always cannot straight 1 even after done alignment ( bush problem )
2.whenever you pump petrol,the needle won't go up till the top ( fuel pump problem )
3.when drive through uneven road got sound like metal hitting something ( problem still not solve as many ppl tried and got post this problem b4,but for my car the sound gone after some time )
4.fuel cover leg broken and the clip fall off ( nowadays if u really see on the road,alot of persona fuel cover is black color,reason is they went back to claim the whole cover but only black color available,if same car color have to wait almost 1 week,i changed mine b4,they sprayed the color not so same as my car 1,lighter color.
5.when the car drive until 100km the pedal there got vibrate,felt quite uneasy also but after i changed the aftermarket lighten crank pulley - problem solve,dunno what is the problem also.
6.Rear boot can't open with key,after i went to sc and complaint,they fixed it for me.
7.When on aircond got sound
so far all the problem above is what i am facing b4 in past persona,only problem num 1 not solve yet,i also very boring dy go to sc here and there to claim waranty,then have to wait also,my car also pay 9 years 1,at first i also thought the car very good,after drive for some time,the car is bullshit,no pick up,body very heavy and quality sucks,a bit better than gen-2 only,then i piss off,since things already happens and i got the car,i start to mod it,after modding it,my petrol even better than b4,my pick up much more better than standard persona,can ditch 1 1/2 car if race with standard persona,btw,if you want to claim warranty or service your car,dun go to the 1 located near kesas highway,big only the place but they do work no pro,go to glenmarie proton edar or those small shop near your place even better,if you plan to still drive this car,i suggest u change the extractor to 4-2-1,then add bullet and change muffler,change drop in air filter,change ligten crank pulley,cam pulley and change your tyre size to 195 / 55 then your ride will be much more better and petrol also save.
