New here, haven't had time to read through this thread completely. But may I ask...
If any of you had trouble navigating uneven surfaces on your Alza? I found that it tends to cause loss of stability in mine, even after switching my tyres. As if there's a sudden loss of traction. |

Is there any way to fix this? It seems very dangerous. I've tried going over a curved, uneven bend at 60km/h once, nearly crashed as the vehicle totally lost control. Never happened with my other cars even if going faster.
QUOTE(miraclejustin @ Sep 5 2014, 06:04 PM) alza generally lack of stability specially on uneven surface. Passengers on the back can clearly feel the horse ride.  |

Yeah, thanks.
At first I thought it was an oil slick, but I've since confirmed it isn't. Quite worrying when you lose traction even when going slow. QUOTE(miraclejustin @ Sep 5 2014, 06:36 PM) alza might be bumpy compared to other car but I haven't experience any lost control over it b4. Tried sent to SC? wait other Sifu here to answer this. |

No, tires were replaced with Michelin tires first chance I got. I guess we're in agreement that the stock tires are sort of crap.
QUOTE(Eithanius @ Sep 6 2014, 04:24 PM) First things first, are you still on stock tyres...? |

So basically Alza is fitted with wheels which are relatively imbalanced compared to the size, causing...physics to happen. I'm no engineer, but never thought of it since I figured for FF cars the center of gravity would be towards the front because of engine weight. But you might be right, from the side it does feel a bit odd given the tyre width and positioning.
How about suspension, is there any tweaks I can do to alleviate the handling? Seems like switching to "stickier" tyres quite a short-term response. QUOTE(Eithanius @ Sep 6 2014, 07:49 PM) Secondly, Alza has a fat ass, and an overall tall body, tyres are too small to even makan on the road. Unless you pasang Michelin PS3 which may improve slightly. Even Michelin XM2, though better than stock, won't provide much traction at such speed on a curve, uneven bend... This is not a sedan which has lower center of gravity. Thirdly, Alza has no Electronic Stability Control, which sucks considering Alza is the top of the line Perodua model... Consider yourself lucky this time. Once you really lost control, it's bye bye... Welcome to your worst nightmare...    |

It's not uneven as in holes or stones, more like what above poster noted. Badly patched roads which dips slightly, or roads with uneven "angles" due to soil sinking or such. Nothing much to set it off, just a slight (5% incline/decline?) imbalance on either tire will cause a loss of traction.
QUOTE(Kiefer @ Sep 9 2014, 08:28 AM) Maybe share the location of this road.. maybe got other Alzarian here passby there too. as we can't imagine how bad is the uneven surfaces, and also when you said loss stability... |

I do alignment frequently, it happens even after a trip to the workshop.
Strangely for higher bumps and dunes, it'll gain traction rapidly. But with sinking spots, it's as if the car depresses in one direction slightly then loses traction for a while. Any slight, sudden steering will cause a loss of control. In some ways, it feels like hitting an oil slick. I can feel the instability at speeds as low as 50km/h for gentle bends. Braking seems to help, but it's quite shaky to steer across the bend without braking. QUOTE(Kiefer @ Sep 10 2014, 08:35 AM) ok.. uneven angles / soil sinking type. This type of sinking nowadays a lot especially the place with MRT construction. Such uneven patch, it will slightly off when one side of tyres goes in, but when you said loss traction, i am a bit surprise as only 5% incline/imbalance. what is the speed you taking...? Have you check car alignment? |

It's a 1st generation, since launch. I thought about suspension problems too, but haven't had a chance to check it. Was going to ask them to test on my previous visit, but they said nothing about it. Maybe I'll ask them to test properly again this upcoming service.
QUOTE(Kiefer @ Sep 10 2014, 05:03 PM) I am not sure about others.. .with 50km/h, i don't see any problem with my alza. Seems like the front tyres not gripping good. How old is your car? have changed absorbers? |

Thanks for the feedback everyone. Will do as suggested on my trip to service center next week.
How over is over-pressured BTW? I usually pump 34 as per suggested by Michelin, is it over? QUOTE(therain01 @ Sep 11 2014, 01:26 AM) Try to do some troubleshooting with your suspension. Push your car down with some force. If you can barely push it down, absorber is dead. If it bounce back very fast or continue to bounce after lifting your weight, you have a weak absorber. Test it on both front and back. Btw, I guess you did check your tires pressure where it is not over pressured. |

Some updates to my handling issues, been a while and 10k miles later...
I've made a trip to the SC to check on my suspension thoroughly. Apparently they claim there's no issue with the suspension and could be the alignment. Which is actually just a shot in the dark, since I've had the same issue right after doing an alignment. For now the issue still persists, vehicle is unstable on uneven roads and traction loss is sometimes an issue. I've taken what a few of you have suggested, that it might be the vehicle's physics/weight distribution. So no solution for now, just have to drive a bit more carefully. my previous cars have all been sedans, so could it also be my driving style? Much thanks to all the input I've gotten from this thread, thank you all who replied! P.S.: Strangely, vehicle handles better in the wet than under hot conditions. |
