Did you try test driving another S5 to see if it has the same vibration issues?

I've tried and can't find one to compare it with.... there isn't any pre-owned, new or even demo's within 100 miles of here !!!

Did you see sizzle's link in his reply? It appears that this was an issue for others as well.

Here is a search query for you.....
