I want to use this thread for ideas that pop in my head about my K5 GT-Line:

The steering wheel is heaven for your hands - thick, grippy leather, flat bottom is a hoot!

The all new eight speed automatic transmission is delightful; manual shifting speed is close to a DCT. Auto shifting is a blast too, in sport mode it will hang gears aggressively. Just plain fun.
No CVT’s for me.

The all new chassis is tight as a drum, and light as a feather.

One thing that I have noticed is that when I get on it in sport mode it will hold onto a gear longer than I expect it to. It seems like it holds fifth gear for a while after I get off the gas and it doesnt upshift.My other two Optimas did not do this and I was wondering if this is something normal.

In sport mode the transmission is programmed to hold those gears, it’s so you can lift going into a corner without losing instant power through the corner and out of the corner.
When I posted about it earlier, I labeled it aggressive.
I like it, but I can see how it would take some getting used to for people.
Best thing to do is just leave it in normal mode or manual shift if you don’t want the hanging gears.
Also, don’t forget that this is an all-new eight speed transmission and is not the same as any of the ones put into the Optima.
It’s made to be more fuel efficient and more exciting to drive.

One last thought... You can also use the custom driving mode and tell it to just change the transmission to normal, and it’ll leave all the other variables in sport mode. You can custom set it anyway you want.

Have you encountered any squeaking inside? It is pretty bad, I do not recall it on my drive from the dealership to my home but it is coming from the ac controls area, if i move that area a bit (shake it) i hear the sound. I felt underneath it where the storage area is & I can feel a minor gap above. Not sure how this can be taken care of, I might try to take care of it by fitting something in between the gap before taking it to a dealership, I guess?

Yes. A Youtube reviewer had a pre-production unit with that squeak. It was the a/c controls alright. Right side. When you push on it it does make a squeaking sound.

I test drove one it didn’t have any squeaks at all, and the one I own does not have any squeaks or at all. However if I was to push on the right side of the AC controller panel it makes a little squeaking sound so I know what you’re saying.

I would see if you can stop it yourself with some silicone spray or some type of rattle stop spongy material to keep that AC control unit steady.
The dealer is going to be dumbfounded, show them the issue.
If they get enough complaints Kia will issue an official bulletin with the recommended repair and any parts necessary. That’s gonna take a while.
A good technician could fix it with materials on hand, but dealer techs are not paid to be good. Might work, might not.

In one of the Kia k5 groups I belong to there were several people that had the same issue. Apparently it is now a known issue to Kia and they will put in some extra adhesive somewhere on the passenger side climate control area to prevent it from squeaking.

Good to know I'm not the only one, unfortunate but it's a brand new model so I guess these things happen.

Also on the freeway today I could hear like some wind noise on driver side, as if a window was slightly open.

Gonna jot down my issues and make sure they can be replicated before going to dealer

The car is much quieter than previous Optimas. This makes the car seem more powerful than it is because you can't hear the engine working hard. Its an illusion with only 180Hp, but it is very effective.

Sport mode makes a huge diff, and I can only drive in that mode. It should have been the default setting.

I’m not gonna specify speeds, but this thing is silent all the way through the speedo range.
Things like double laminated glass make it unusually quiet and composed.
The all-new chassis is solid, quiet, and light (3115 lbs).

The AC controller panel squeak on some early production units can be cured easily with some silicone spray and/or some foam.

It was specified in a review on factory supplied units, and I’m sure Kia monitored it and will have a simple factory approved fix soon for any units affected.

The windshield is special but windows are not double laminated. This means it could have been quieter if they wanted.

I see that now. Windshield is double laminated.
I’m sure that’s the noisiest piece of glass on the whole car which is why they did the windshield alone for cost effective sound reduction.
Testers with a decibel meter show that it’s one of the quietest sedans in its class.

Random:

Dropped my ballot off Wednesday at a drive-through location, and the nice people working there really liked the K5.

I took the long way home.

The seats are supportive and comfy.
Power lumbar (some models) keeps my cranky back happy with infinite adjustment.

At 6’5”, I have more than enough legroom and headroom (without sunroof)
- with sunroof minimal headroom, unacceptable for myself.
Sunroof takes away 1.8” of headroom.

Air conditioning is excellent with temps in the 90’s, and high humidity.

I didn't notice the squeaking in mine until the next day. I took it back to the dealership and the GM took me to the service department where the manger said they'd have to pull it apart because it was the plastics where they meet just above the ac control unit. I said no thanks because you're absolutely correct about the dealership technicians. Not that they aren't good or know what they're doing, it's more like the pressure to get them out as quickly as possible to get others in is what seems to hurt them. Management is more worried about bottom line and numbers rather than outstandimg customer service. I'll deal with the squeaking and one day find my own little solution. If not, I'll deal with it. I am usually driving with music and pay no mind to it anyway.

Try some silicone spray first.

I think you made the right choice about not letting the dealership take it all apart.
The real issue with dealership technicians is that they’re paid by what’s called flat rate.
They only pay for each operation individually and the times are so low you can’t make a living doing warranty work all day.
So they blow it out quick, and try to get some customer pay tickets.
It’s the automotive industry as a whole that makes it this way, although there’s a few like Lexus that pay the technicians by the hour instead of by the operation.
The only other tip I could give is to meet the technician working on the car, and hand him a $20 bill and tell him lunch is on you.
This may allow him to take enough time to do the job properly.

Let us know if some silicone spray silences it.
