Hello, I'm a NOOB here in the forum, but I've been working on cars for quite some time now. My background is mostly in electrical design but I'm a bit of a motor head too. I'm a speed demon. I love to fly. The faster the better, and even better in style. I've owned several Korean cars. Variations of the Lambda and Theta motors. Tweaked each one of them. I'm a big fan of where Hyundai / Kia is heading. When they stole Peter ( offering WAY more $$$$ ) things changed drastically. You are seeing them taking the gloves off and coming full force. The concept designs both inside and out are amazing. Take one look at the Stinger. Look at the new Genesis Coupe coming, take a peek at what's on the drawing board ( next three years ). I read an article the other day saying that Hyundai / Kia intend to go head to head with Lexus by 2017. Personally when you look at the total package of cars like the Cadenza, K900, Genesis, Eqqus. I think they are already there, and at a better price point. - Just my opinion. It's a true pleasure to be here and I will try and help in anyway I can.

Welcome aboard! So what's your take on the start up engine noise? I'm thinking it's the filter. Maybe the lack of a drain back valve? I notice it's not that bad once the car is warmed up.

I have a friend who works for them indirectly of course - but he is a master tech and at the largest Kia dealership on US soil. I posed that same question to him. His response was surprising. - " Kia used a carbon based proprietary coating on several parts within the G6DH engine variant. This was to help with friction, wear, compression etc. But it seems as those coated parts move ( COLD ) there is what some call an echo,rattle,shake. - I've heard several people call it different things. Once things heat up a bit and the oil moves freely - no noise. " - I've seen this issue with other car manufacturers motors too though and the cause was different an example would be GM // the 3.4L motor used in several vehicle applications. The issue was oil not getting to the top of the motor right away until a warm up period of 1 to 2 minutes then no noise.




I have heard the sound from my Cadenza but it's not really bothersome to me yet. Only have 4,400 miles on it and the sound lasts for maybe 30 seconds for me. What kind of mileage did you notice it, or was it right away for you ?

it was right away I'm up to 12,000 and climbing fast. The dealer said it was the injectors being at high pressure for direct injection but it goes away in 5 seconds. My concern is it's a dry start because of a oil filter situation.
Here's one for you, how to disable the auto wipers, or at the very least disable the HI setting they go into. Very un-cool! I want my intermediate wipers back!

hmmm,,, I don't think fuel injectors would make the sound and in 5 seconds. The deal with the wipers I was messing with mine today ( it rained ) - LOL perfect timing. So I set them to AUTO,,,, then just changed the speed setting variable. When I pulled out of the garage they came on slower not full blast. Have you tried turning the adjustment where you want them to be ? I have the premium version but I'm pretty sure the setup is the same for all models. I upgraded everything to the SXL specs except the wheels, I'm not a fan of all that chrome. I'm also not a fan of SXL either. I changed out my badging. In several other countries they have no idea what the heck SXL is. I used blue painters tape and came straight across from cadenza top and bottom, ordered the OEM LIMITED emblem and centered it there. Then below it I added badging for 3.3 followed by the T-GDI badge because they don't have anything for a turbo V6 yet,,,, until the OEM 3.3 T-GDI motor hits in the GT / Stinger - and I'm not sure how they will badge it, still in concepts stage - photos just show off the GT emblems etc. ,, I've seen the spec sheets horsepower is an extra 100 to 120 ponies depending on who's running the numbers. The torque curve looks good and the power to weight ratio as you can imagine is insane. You can see a ton of Audi's influence in the engineering, and it's pretty impressive. I'm a big fan of Peter Schreyer, looks like he is leading them down the right path. It's too bad for Audi,,, that they lost him. He's a BEAST.

yes I used the adjustment. It just makes it worse. The auto wipers feel the need to go to full speed. I'm not a full speed kinda guy. It makes the person driving look like a dork.
