vibration at take off

My dealer sure does have a new Cadenza ready for me to use. But, I can see why yours probably would not. Why did you buy a KIA anyway; go back to a Chevy Cavalier.

Yuck with this guy; go away.

Ha, I'm happy that your dealership is so awesome! Unfortunately you and I are having two entirely different experiences with our vehicles. So as expected we have two opposite opinions on what we expect from the vehicle. My dealerships in the MD/NOVA area have maybe 1 or 2 Cadenza's on the lot, and don't have a single loaner.

I've never owned a Cavalier so I'm not sure what that means.

I bought the Cadenza because it had a load of options that at first glance (10 minute test drive) seemed to be extremely intuitive, functional, and state of the art. If you have owned the car for more than a month, and have not noticed the many short comings of the infotainment, electrical equipment, and the vehicle in general I'm not sure what car you're driving. To top off finding myself in a community of people who are writing KIA complaining that their GPS speed does not match their speedometer speed. Having a hard time opening an already opened trunk. Complaining because their seats don't match up to their key fobs. Who knows what else is coming our way. The car is a straight out disappointment.

I did try to trade it in and move on, but unfortunately even only having 2,500 miles the car isn't worth a penny.

Do I think the car is a worthless piece of ****? No, not in the slightest! It is still a decent value for the amount of options delivered. The unfortunate part, with electronics ... you get what you pay for. So we didn't pay the market value for all of the items packed into the Cadenza, which means our items don't function the way the comparable electronics in other vehicles do function. Then you go look at a vehicle like Ford, while still a POS that can't even install a head liner correctly or put on a fender aligned with the rest of the car. Their electronics while slow on the interface, at $30,000 you get everything in our cars and more with better functionality. Will that functionality last? Probably not, but it's there.

So an overall summary of the vehicle, at first glance it's the best value for your buck.

At second glance. It's a vehicle with a horrendously under powered engine that gets horrible gas mileage, poorly planned interactive infotainment, and last generation technology that has came leaps and bounds in the newer generations and you are missing out on it! Be happy! You have an outstanding warranty! Which judging by the massive leasing community with this vehicle makes that is entirely irrelevant.

Cadenza goes in tomorrow to have the first service...They will be looking into the vibration/shudder at take off issue...its very much still there. I even applied a bit more braking while turning and the thing shuddered so bad I thought something in the front end was going to fall off..I am curious to see what is causing this issue.
It seems to be getting worse and even at idle my wife says she notices it..now I am thinking bad mount maybe? Oh well...guess I might know more tomorrow..

Other than the shudder we absolutely love the car. We get about 33 mpg on the freeway cruising along not even trying. We couldnt be happier with the fuel economy. As for power I have no complaints..it pulls just fine and over takes vehicles easily. To this day we get compliments everywhere we go about the car. Hopefully the dealer will straighten out the shudder..

Well...Dealer said that its normal..lol

I went on a drive with a tech and he did a power brake and throttle and the shudder (growling feel from the engine/trans) presented itself quite a bit. So I left it there overnight and they told me the next day that it was normal and 2 other Cadenzas did the same thing. They also told me that the rattle noise on start up is totally "normal" for Cadenzas as well..lol...

So basically any issue that comes up seems like its always going to be determined as "normal" for the car...they all do it lol..

So lack of oil pressure in the top end at start up is normal..umm..yeah right. Cant wait to hear how Cadenzas and other Kia's with the same engine are doing at 80k miles...

Anyone care to press and hold your brake pedal while giving your car some gas and let me know if your engine/trans makes a shudder with a bad growling sound? I am curious if any of yours do the same thing?

No the engine doesnt shake...the rattle at cold start up is your valve train clattering because theres little to no oil in the top end until pressure builds up and the oil reaches those components...

The shudder doesnt make any noise if you take off from a start normally..it just shudders..doesnt buck roughly but rather feels like a front to back wobble in the driveline..if you stop the car and hold the brakes while pressing the gas the "shudder" gets a lot worse and theres a loud growl sound that sounds like a bad bearing spinning....

Again..all normal..lol

Bad thing is that my in-laws are seriously looking at the Sorento and the Cadenza and at this point although we love the car in every other way I will have to tell them my issues and the lack of resolution from Kia...my old man was just about to pull the trigger on the K900 and because of my issues and telling him its normal according to Kia he immediately changed his mind...

Oh well....I will just turn it in when the time comes..I am not comfortable with the attitude that I should drive it doing all these things until it lets go or blows up because it has a warranty...
