I don't mind helping you guys... but how many person? What tyres you all wanted to change? More info will be much appreciated.

ps: I will not be around for whole week, might able to get you all info next Sat earliest

Just ask a general question how much they willing to accept Nexen tyres for Michelin.

You all create a list those who really wanted to change, i go ask.

Hey guys, am sorry and really hate to interrupt u guys...

But can all the optima owners contribute to my questions here? I would really appreciate it...

Am a new guy here, was plannin to get 508, but now I want to see the optima side of the story..

First of all, I have heard the wind noise can get a bit high(>60mph = >100kmh) according to the US optima owners, can u comment about it from ur experience? anyone reached 160-180kmh in optima before? how is the cabin noise or NVH in compare to 90-100kmh?

Secondly, I have heard a lot of US Kia optima owners complaint about transmission problems and similar complaints are piling up more as days go by, do we hav the same problem in m'sia? (they usually are like 'driving in highway one day and suddenly the car kinda leaped forward as if the car hit something in front with a big clunk noise coming from underneath the car, and the rev all of sudden raised to around 4-5000 and gear stuck in 2nd gear (sometimes 4th), then wont be able to change the gear either wit paddle.. then turn the car off then on only able to fix the problem, the car then behaves quite normally for the next 3-4 days then comes the transmission failure and for that kia SC in US usually changed the whole transmission for these owners' am not sure if the same thing has ever happened to m'sia optima owners, and if so, how did naza fix these issues? (since it is known naza's after sell services are horrible)

Lastly, the burning smell that was mentioned not long ago, anyone has figured wat that was?

Thx guys

The K5 Optima was out in the US market for a couple of years already. Can you verify what you read is something recent or is it something that was mentioned in the past?

A good Samaritan has come up with an extensive test script on the 'burning' issue in a few posts back. Expect to get some feedback within the next couple of days.

Stay Tuned

Welcome!

Can you post some links with the indicated problems for the US Optima?

As for the wind noise, i have tested the car right up to 120kmph and i didnt pick up any wind noise. Not sure how it is at higher speeds. In fact i was surprised that there was no wind noise from the sunroof (which is a common culprit). The NVH in the cabin is very good. At standstill and with the aircon off, you will never know the engine is on unless u look at the RPM meter. You only feel the engine noise when your RPM crosses 3000.

But when you ask about wind noise, its always best to also ask the person which car he was driving before. Most experiences given are based on our previous experience. So if a person was driving a Persona before he would find the Optima super silent while a Altis user might say the Optima is only marginally better in terms of NVH. Trust you get the idea.

There is no wind noise until about 160km/h..
At that speed there would be minimal sound..
I have touched 190km/h and only experienced minimal wind if i concentrated hard enough...haha
So no issue on that so far.
But the tire sure is noisy, don't mind changing to Michelin if get a good trade in value for the nexens..

Thnaks guys... really appreciated for all ur helps...

The complaints were all in June-July 2011 and before... think the last comments in the forum was 30th Aug 2011...

Here is the link to the forum...

http://www.kia-forums.com/4g-2011-optima/6...mission-10.html

Just get the Optima la dude. Drop the Peugeot 508. Optima is Rm27K cheaper. Are u trading in any car? Have you test driven the Optima yet?

Good suggestion. Will do that soon

Added on March 31, 2012, 4:31 pmNoted. Will correct

Added on March 31, 2012, 4:33 pmHmmm, strange because the SA told me it doesn't and when I tested the paddles in D, indeed, there is no difference. Nevertheless, will note this in the blog and anyone else is free to comment

Oh, SA also mentioned that the initial batch of 100 units brought in for the launch has no rear blowers whereas current ones have. Anyone can confirm this?

For the past few weeks, I have been decided to take optima till when I first saw the 508 forum few days ago...

Sorry, nope, not yet, I hav not test drive it yet since am still in overseas, since the beginning of this yr, will be returnin to m'sia around may-june this yr..

I always respect people express their own opinions in any forums. Some are really helpful information but other may not. I would advise you follow your heart. I have tried 508 and Optima. Both are good cars. I choose optima

Those without the rear aircon vents were 2011 units. All 2012 units have the rear aircon vents.

Added on March 31, 2012, 5:24 pmOk then you have some time to read up more on both cars. But no matter how much u read, it can never replace a test drive. Ive tested the Optima 7 times already and im more or less certain. Spend some time on this thread and ull learn alot about the car.

WOW! Thats gotta be the longest response on this burnt smell issue to date

Well, to be frank, the smell that ive been getting is not similar to hot asphalt (i too am familiar with asphalt). The smell that im getting is more to burning rubber which is why my first thought was the tyres. The 1st time i got it, i drove aggresively with high reves and hard braking. Then to eliminate the possibility of tyres, i stopped the hard braking and went with just high revs. The smell remained. Sometimes ull get a burnt smell after you change your belting which is common as the oil coating needs to wear off. But this smell im getting is different. Ive even got the disk brakes checked and there werent any issues there. The smell seems to be coming more from the drivers side (or maybe i get it more here since thats the first point of contact when i get out of the car).


If its indeed the anti rust, how come ive not noticed it on any other car either from Kia or other manufacturers? And if its indeed anti rust, why is that the smell is only present during high revs. Normal driving doesnt produce this smell in my experience.

The smell that im getting is more to burning rubber which is why my first thought was the tyres
Did some short test in the morning by taking some sample and burn it by lighter. My apology as for my first prediction is a burnt bitumen smell but the smell come out is a “BURNT RUBBER” or as you said burning rubber smell…..and its confirmed by you as well...and from this test I can said that we got the culprit. Its from anti rust. Try to get some small sample from show room unit and heat it using lighter. Others owner can do this simple test as well to confirmed the smell and I think this answer your question about the main issues = BURNT SMELL

If its indeed the anti rust, how come ive not noticed it on any other car either from Kia or other manufacturers?[/U]
I can't confirmed this yet as this need to check under carriage by visual check as its involved area of spraying of the anti rust material which when they spraying of this anti rust ether its include or perhaps some amount of anti rust over sprayed to the exhaust system as we don't know how the anti rust guy doing it and how the manufacturing plant lay-out is either all the model in the same plant with a same person doing the anti rust spraying or in the different manufacturing plant. Same to others manufacturers, we don't know how their procedures and their internal standard on how to sprayed the anti rust material.

And if its indeed anti rust, why is that the smell is only present during high revs. Normal driving doesnt produce this smell in my experience.[U]
It's all cause by temperatures.

Acceleration = High Rev = high exhaust system temp = burnt the anti rust material = Burnt smell.

Normal driving = Medium rev = medium exhaust system temp = No burnt smell

Exhaust system is not come with the system or cooler ( such as radiator ) to maintain the temp at certain temperature. It just fabricated from a tubular steel that can stand high temperature so it’s possible to have a range of low, med and high temp from the exhaust heat produce by engine rev and with that range of the condition it will reflex to the burn point of the anti rust that stick at the exhaust system.

It’s just a theory but to confirmed it, we need to plug or embedded the temperature sensor and smell sensor at the anti rust area that stick at the exhaust system and monitor at what temperature the anti rust burned and produce rubber burnt smell.

Guys,

Just back with my K5 for alignment. It seems that, the SC Mgr told me that <5000km, u still can do ur alignment FOC.

Also, I highlighted the burnt smell issue that was brought by CM98.
So, this is the answer they gave me. Not sure if this is correct or not. Sifus, pls verify this. (I had to ask few KIA people there until I get this. others are hopeless)

> He told me it's from the catalytic converter - which is the exhaust emission control. The job of the catalytic converter is to convert harmful pollutants into less harmful emissions before they ever leave the car's­ exhaust system. It convert CO, Hydrocarbons & oxides of nitrogen to CO2, N2 & H2O.

Just like the explaination by RlanD but,
Acceleration = High Rev = High amount of conversion = Burnt smell.

Normal driving = Medium rev = Medium amount of conversion = No burnt smell.

Since the exhaust running right underneath the aircond blower, probably that's how the smell leaked in.
It might be due to failed catalytic converter but I reckon most probably not as the cat converter failure since it's new car and the smell should go away.
The bad news: A new cat is expensive.
The good news is it's probably covered under warranty. Check with your SA

I havent experience this on my K5 as I probably havent drive as hard as CM98 did ---> to sayyyyyyyang my bright silver.
Well, I hope this help. If it doesnt, we all can try ask KIA some more! Or it's just a plastic bags got stuck at the exhaust and got burnt. hehe
