Vibration while backing?

Anybody notice a little vibration while backing up? Its louder when backing on an incline and happens when you press on the pedal. It doesnt do it when you put it on reverse and just let the car back up on own.

Do you have a GT2 with the LSD? I hate to say it but it might be the rear differential issue that has become more common lately. My Stinger was one of the first to have it completely replaced in the USA and many people in Australia have similar issues.

Try making a figure 8 or at least a tight u-turn while giving a little throttle. If it makes a whining noise, shutters, or you feel alot of drag its probably the LSD and would take it to Kia Asap!

Heres a thread about it and i have a few posts in there describing my situation.
Broken Differential

Hope you dont have the same issue and hope this helps

Yes it sounds like the LSD problem.

Contact the dealer and they should be replacing the diff oil.

Went throw all 4 pages of the thread. The symptoms might totally be different than mine. It's more vibration than sound. I also tried uturns and figure 8 no sound. I'm going to knock on would and hope it's normal. It's not crazy vibration and if it is it feels like its coming from the engine or transmission.
