Scratched my rims 
Can't be polish ..tried many times.. Sad.. 

I seriously have no idea how you guys could clock 650km... Best i tried was 580km with ECO mode on during traffic jams only. However, FC really did improve with higher mileage. I dislike ECO mode, it makes the car lazy and draggy, so i turn it off all the time. 

BTW, i need an answer pretty urgently, now that i've clocked 5250km and next service is 5000km. So does it mean i must send the car in for service now? or do they mean first 1000km + another 5000km = 6000km for the second service?

The steering wheel jumping around is the issue i brought up before in the previous thread. I have researched this and its nothing to do with the Nexen tyres. The Optima has a 'problem' which is called as 'steering kickback'. Not a big issue but u just gotta hold on tighter when u go over bumps or rough roads especially at higher speeds. Not sure if Kia intends to correct this or when.

Hi, may I know the servicing interval for the Optima is every 3 months or every 10,000km? I seldom drive so in 1 year also never reach 10,000km. I have bad experience with Honda. They require servicing every 3 months even though I hardly drove the car. Not worth it.

list updated .. for more info ..

pls provide me your K5 color .. thanks.

or not also can

The side lights only light up when the steering wheel reaches a certain degree of turn. Not sure what it is. Try taking sharper corners and see if it works.

Hi guys, wat ave speed reading r u getting? Mine strangely reading 26km!! I reset it after fuelling up in klia petronas n got onto mex. When i got home, it read tt much only. I definitely didnt go tt slow. A potential issue?

Just came back form Penang yesterday and wanted to share my fc (and also for those who are looking for some info on K5 fc). Not sure if this is comparable to other D-segment but this is what I got.

City/highway around 25%/75%
Mileage 830km and still got 2 bar left
pump ron95 for rm120 (around 63 liters i think) full tank

Started full tank in Segambut area, then go up to Penang (include BM and Bagan and stay overnight at Perai)
Next day go up to S. Petani and up to Jitra then come back to Perai to stay overnight.
Next day travel down to tapah only pump petrol.
Driving Style: light on pedal and max speed only about 100 to 110km/h.

Feels like the fc is better now compare when I first got the car. 
oh.. btw... found out something about the K5 the other day. (something I am not aware of at all)

I use the smart key to lock my car. All is good. Then wanted to check if my boot got lock properly or not cause got keep some expensive things inside. Press my fingers to open the boot and IT OPENS. I was like  , my boot cannot lock?? I got faulty car?? Makes me    and want to go see my SA next day and complain. Later I think, think, think, that MAYBE the boot can open is because I have the smart key in me and it can detect that I am nearby so it allow me to open the boot. So I pass the smart key to my wife and ask her to stand far away and I go try to open the boot again. Guess what.... It cant be open. This is one of the features that I dont know about. What a relief...

Silly me . Looks like the car is really smarter than me... 

I tested the FC on the Optima on highway drives a number of times. At 110kmph the instant FC is 9.1L/100km while at 160kmph, its 10.2L/100km. So it actually makes more economic sense to drive at 160kmph as the FC difference is only about 1 liter every 100km. So if ure driving from KL to Ipoh, driving at 160kmph would only consume RM3.50 more compared to driving at 110kmph but ull reach faster thus your extra 'expenditure' is nullified.

what do u mean by "cannot" ? the gear 6 in shift mode will turn to D ? or the car cannot reach 160km/hr?

gearbox issues? I got no problem driving up to 190km/hr. Look for SC and try it out with him in highway.

Well, complaining more may not get you the desired results. Right now, the fact is that you made your booking in early May and now its just 1.5 months. My advice would be to just be patient and wait a while longer since there is nothing much you can do and 1.5 months isnt exactly a time frame to warrant a mass protest.

But do keep in mind that this thread is visited by owners and also potential owners. Although we need to be transparent in our complaints but let's also be a bit tactful. We all know that the K5 is a great car for the price we're paying and we want others to have similar thoughts as well.

Im sure there are underlying issues that need to be resolved by Naza and im quite sure they are doing their best. Its not in their favor to have cars sitting at docks and at showrooms collecting dust since they are paying for storage but not getting anything in return.

I would love to see more Optima's on the road for sure but we all know there's a problem so just give Naza the benefit of the doubt for now, shall we? 

Soma is very professional in dealing in customers. Always like dealing with him bro...So far no complaints..
