hi guys, I'm an owner of Alza middle spec year 2012

I have issue with my power window button whereby sometimes work sometimes not working either press to give the window go down or vice versa. Worst case scenerio when I get both passenger button and driver button also not working, I need to switch off engine and start back to let it work back.

second issue i have, all 4 doors been bugging me as when it close it was not smooth like other car. If u close too soft end up it doesn't lock hence u need to close harder. I told SC before and they told me it was the cabin pressure. So every time i need to leave a tiny space from my window so I able to close the door at average power. this issue been bugging me since the first week i take the car but at first i thought becausw of new car that why got this issue.

third issue, i felt the car was underpower. Im a sales person therefore i need to travel quite often. My car up to date mileage already reach close to 90k. everytime i pass ipoh mountain i need to shift my gear to 3 and press hard pedal to get the speed of 100 to 110. on normal highway fastest i test before was at 160km/h and feel like the engine kinda stress d.

my FC also quite high, i tested before from KL straight back to penang from full tank till reach penang it left 1 bar and I pumped my petrol at RM 66 @ Nov fuel rate.

beside this, any sifu can recommend me a good HU with waze navigation and rear parking camera? budget quite tight.. hope below 350

any advise from sifu out there?

Thanks for detailed summarized...

will visit electrical workshop to check the wiring connection

will door hinge is an issue here? i owned a vios as well, for vios door no need to use energy just a slight push will make the door close. where else alza each time when i have all my window wind up i need to use some pressure to close the door, if i leave a gap in window it shows slighty better.

for hu with waze and reserve camera, what is and ideal budget i should look for? im looking for affordable price if can. currently im using my note 3 for navigation and avoid speed trap
