I sent my car to the service centre to check on the problems mentioned above. Below is the outcome:
1. high RPM during cold start - this is normal (according to the service manager, the car need to bring up the engine temperature to at least 80 degree celcius)
2. Hum sound - he suspected is due to the ABS pump, so now he took out my ABS and ask me to try for 2 days. However, yesterday after he took out the ABS, I experienced that hum sound again, this time is when the car idling and i switched on and off the aircond. so far is happened once and i couldn't simulate the problem again until today.
3. minor jerk - he couldn't detect any and similar to the hum sound i also couldn't simulate the problem until now
4. front door loose - he told me there is nothing for him to adjust.
All these intermittent problems really difficult to resolve...sigh.
I sent my car to Advantegarde in Bandar Tun Razak. If anyone of u having the same problems and found a service centre which can resolve the problems do let me know ya.
Thanks.
Hi guys,
I got possession of my Standard Spec YF on 30 Aug and todate is about one and a half month and had clocked 2088km up till today. Bro wkcheah really oustanding to clock 4000+ km in such short time!
Here are some of experience of my YF:
1) Yes, mine also having high RPM when start from cold and glad to know its normal;
2) Hum sound also got. I was suspecting that it might be due to the fan? Actually my previous car, Matrix, also acted similarly. The SC told me that the fan design for that car actually will run at higher speed when the engine is hot. It's not that the its overheating, just that it will try to keep it at optimal temp when the sensor sensed that the engine is hot. So i guess YF should be similar? This is quite technical so maybe the SC need to read up the service manual a bit.
3) Minor jerk at low speed also got. Actually i think its due the gear ratio but need SC to really confirm my logic. I reckon that the YF when travelling at low speed or low RPM, the gear shifting might change or at times might shift to higher gear. So in fact sometime i even feel all the sudden it's picking up speed eventhough i did not accelerate.
4) My doors are quite ok. So far nothing wrong with it.
5) Hankook Optimo Tyres .... i would say its a bit noisy and bouncy. Was wondering what tyre pressure you guys put? Anyone tried nitrogen? Technically should give lower noise and better grip right?
6) Handling, so far the fastest i did on the car was 160km/h on a straight stretch on MEX h/way to Putrajaya. On straight line i think it is gripping ok but when taking high speed corners somehow its not gripping well. Maybe due to wrong tyre pressure? or prob i'm not really used to the lighter steering. Can someone give some input?
7) Acceleration ... its great when you tekan a bit. I think the car has enough power to out perform many of the same class. But that is just my feel without any actual test
8) Looks. I guess no need to say already. It's really a head turner. So far it attracts many attention and i hope those that was starring at our car know where they are driving. Hehe, we don't sekali accident due to looking at YF plak :")
Overall I am really satisfied and proud having this car. Cheers mate!
