Add me to the list:
1 Wind noise > 80km/h
= Acceptable, never expect Perodua NVH better than others
== Agree
+++ If say above 110kph, acceptable lar, but below 80kph already can hear. Whoever rides on my car always ask why my radio reception not clear one, got static one. I said it's not radio problem... 
Â
2 Loose number plate on the rear trunk door. Rattles when close
= It was stick to the car, screwed it will be better
== Don't have noise
+++ Perodua recommends square plate instead of rectangle oneÂ
3 Engine noisy inside cabin > 110km/h
= Acceptable, better than proton wira
== Better than waja
+++ Don't compare Wira with 3 gear ratio, at 110kph, the rpm is at 3.5k, of coz lar noisy. Alza only 2.8k... Waja no comment, never driven before. Kalau Campro, maybe like ppl said, engine too hard to tame... 
Â
4 Steering veers to the left, slightly off axis at straight road
= Alignment can be done outside to fix it. Use conventional ruler rather than computerised alignment.
== I once had a car that didn't pass puspakom 3 times, and finally a sifu in Klang, old shop, help use ruler. gaotim in 10 min and later pass puspakom's test. Computer? Throw into river la.
+++ Can recommend me the sifu...? I wanna do alignment after tukar donut...Â
5 Roof noisy when rain
= For those car before 2011, you need to report it to P2, it will be better after sound proof material
== It rained this afternoon, ok mar...
+++ Try sitting at the back as a passenger. Driver seat, you can only hear droplets on your windscreen...Â
6 Soft horn sound
= I got no issue, but you can change it to hella horn
== This was the first thing I wanted to do, but the cheapest quote I got was RM350, cause need add amplifier lar, no enough power wo. Betul ker?
+++ I tukar one for RM 120... Not too loud, but better than that chicken shit Perodua horn...Â
7 Power window on driver side not smooth when in operation, jerky motion
= NIL
== NILÂ
+++ Problem resolved, so no comment.8a) Gear shift, 3rd to 4th, not smooth
= NIL
== NIL
+++ Try accelerating uphill, notice when gear shift sometimes you may encounter an rpm spike as if the engine is draggy...8b) Reverse gear sometimes produces sudden strong vibration on car
= NIL
== NIL
+++ This issue requires a complete gearbox change...Â
9 Low whining/whistling sound when engine is idle
= Engine characteristics, noise minimal, accepetable
== Don't have
+++ I paid les attention to it since those P2 engineers obviously don't have trained ears... 
Â
10 Cabin light not always turned on when car doors are opened
= Door ajar sensor, front left and right, their parts got defect
== NIL
+++ Seems like mine recurs again... 
Â
11 Rattling sound of loose part near driver seatbelts on B-pillar
= Yup, I also got
== NIL
+++ Solved it with some Insulflex...Â
12 Rattling sound on dashboard
= Yup, I also got, don't ask them dismantle it and assemble it back, no point cause will be the same or worst.
 This caused by tooling, their original cast for dashboard not good, all using plastics, snapped in, not screwed.
 You will noticed major different, especially day and night. Day more noise cause hot, night less noise cause cold.
== NIL
+++ Even a Honda Insight has it, but Alza was worse. Gives the impression the car is falling apart...Â
13 Rattling sound from rear seatbelts when going over uneven roads
= Yup, I also got
== NIL
+++ Either P2 or Daihatsu/Toyota has poor "organizational" skills...14 Bluetooth not working
= I didn't use before, not useful for me temp.
== NIL
+++ Problem settled...Â
15 Long distance/high speed braking not smooth, car jerky. No hard braking
= Mine ok, got engine braking
== NIL
+++ Try a little continuous not-too-hard braking when approach a toll on highway... Best applied for 5 - 8 seconds when speeding...Â
16 Dirty front rims
= Is brake pads dust, cause by original P2 LUCAS brake pads. You can change others if you don't like
== Clean them every week
+++ If changing them doesn't f*** the warranty up. This kind of car manufacturer loves to find excuses not to grant warranty claims...Â
17 Noisy tyres
= Acceptable, cannot compare with good one
== I must find the budget to change this, not acceptable but it is silverstone.
+++ So bila mau tukar donut, kita gi sama k...? 
Â
18 Leaking water from engine compartment and exhaust, when air-cond turned on
= I didn't notice but Where is it?
== NIL
+++ It's underneath the car, don't ask me where, just last week my mechanic noticed a puddle of water even for a short drive, and says my car cannot tahan kencing 
Â
19 Air-cond takes time to cool cabin, not cold enoughÂ
= Acceptable, my fan blower strong and I got full car tinted
== Ya, acceptable, cools down quite fast, but no one sits on the 3rd row, so my comment is until 2nd row.
+++ My passengers always complain being not cool enough. Now I f***ing embarrass wanna fetch anyone on my car...
Â
20 Soft knocking/tapping sound on engine when accelerating between 1 - 1.5k rpm after driving for some distance. Noise is also present when car is stationary and engine revved at the same rpm range
= Not sure about this
== NIL
+++ You guys don't have trained ears...
Try driving for about 20 minutes, put your car to stationary, and revving slowly but continuously until rpm reaches between 1k to 1.5k. Hard to reproduce coz the rpm window is very small. Rev too soft, you don't get the noise, rev too hard, you'll missed it.Â
21 Air-cond knob can get stuck between "1" and "2"
= My switch working fine
== NIL
+++ I'll show you next time if got the chance to TT...Â
22 Rubber frame on left side front door does not fit perfectly
= Mine ok
== NIL
+++ Shoddy workmanship...Â
23 External door handles too stiff
= Mine ok
== NIL
+++ Fixed 2 doors, now front left door handle acting up again... 
Â
24 Scratches on surface of car on every sides
= Cause by those f!@# who scratch my car
== No comment
+++ Still not resolved even after 2 months...Â
25 Rattling sound from third row seat, loose board on back of seat
= A bit, sometime got sometime don't have
== Don't have
+++ You guys are f***ing lucky. I can't put the 3rd row back seat down without having those noise...Â
26 Stationary and speed brake pedal vibrates when front wiper is running
= NIL
== I don't even understand
+++ Scenario 1: Apply RainX on your windscreen, raining time, drive for 15 minutes with the wipers on. The stop your car, place your feet on both parking foot brakes and speed brakes (do not depress them). You'll feel the vibrations resulted from the wiper movements.
+++ Scenario 2: Get a dude to drive a car with a loud, big-ass exhaust, ask him to park in front of your car and rev kao kao while you lay your feet on both pedals the same way as Scenario 1.Â
27 Steering rack vibrates and noise on uneven roads, especially when turning
= Didn't notice, need to test
== Don't have
+++ For those in PJ, climb up the ramp in 1U-new wing 3rd floor parking lot. Stroll down again. Their parking ramps have rough grooves and curvy enough to stimulate a rack vibration and noise... Steering macam nak tertanggal...28 Front suspension noise when going over speed breakers
= Previously got, now ok
== NIL
+++ Comes and goes, Perodua engineers can't even be sure until my car is sent in... PHAILED BIG TIME...!29 Loose black cover on trunk door causing rattling sound
= Yeah, a bit, can fix DIY
== Mine is alright
+++ Solved with Insulflex...31 Jerky motion during acceleration, possibly another round of gear problem
= NIL
== After service today, I kinda feel there is something wrong some where.... but the driving distance back home is short, will listen carefully when I go out later
+++ Good luck... I can feel like my engine wanna gave out during acceleration...Mine was auto premium, year 2010, mileage 30,102km, average fc = RM 0.15 / km (Esso/Petrons, light foot, tighten throttle cable already). I'm kind of understand your issues and dissatisfaction, our local parts not so reliable if compare to japanese or korean. If I'm not mistaken, this whole car was truly made in malaysia, sometime no luck really will get problematic one.
== You should check his plate number. But wow, RM0.15. Best I ever heard. Can show a pic of your tighten throttle cable?
There you go... Try some of those methods to see if you are plagued with some of my problems...
