I will be buying a 2015 Kia Soul base with 28,000 miles on it. Only concern is that when it is in neutral, there is roughness that I feel.....I feel a slight shaking in my right leg. A passenger in the back seat said he also felt it. Dealer can not find anything, and all the diagnostics check out okay. Many ideas?? Thank you very much!
Some vehicles inherently have slight vibrations in them at idle. My '06 Chevy Silverado with a V8 in it has a slight vibration in it at idle which goes away just off idle. It's just something which can occur. Considering there's no issues on the diagnostics, I'd suggest there probably isn't much to worry about.
The great thing about a 2015 Kia Soul with only 28k miles on it ... It's still under factory bumper-to-bumper warranty until it has 5 years/60k miles on it (whichever comes first). If there really is an issue, which I doubt, the dealership should take care of it for you.
