in steering wheel between 60 and 70 mph. now they are putting on a new set of michelin tires. they do not know what the hell is wrong with it.

yeah, the same thing is happening to me with my A5. my dad thinks it's an alignment problem but they aren't sure.

same here with my A5 with S-line
i think its the crappy dunlops :)
i wish it had continentals

Mine does the same thing

A5 S line Y-19" dunlops...but when driven for a bit the vibration goes away...most of the time.

can be felt at about 43mph AND 62mph

Dealer (HBL Tysons) has looked at it three times and say they cant recreate the problem. They balanced the tires and "checked" the car...everything appeared to be ok. Even left it overnight one time.

next time I will ride with them but the problem can be a bit of a ghost...comes and goes...puzzled...but not imagining this.

driving for a bit?

I was told that by the dealer as well but that doesn't explain all the times it happens... just most of them:)

It still occurs, albeit less frequently after the car and tires are fully warmed up. This happens much less frequently but does occur.
Usually on the highway around 62mph.

Thanks for the comment though.

Im thinking of taking it to a good service center to check for a bent rim, alignment issues, etc in NOVA. Anyone have a recommendation that isn't the dealer? Tired of wasting my time with them.

I have the vibration as well but it has occurred exclusively when the tires are cold up to this point (5200 miles). It happens right around 60-65 mph but is a more subtle vibration than others have described.

Interestingly, I had similar vibrations on both my G35 and 330i so as long as it goes away when the tires are warm, I am not too worried.

prp

funny thing is one of the advantages of the Dunlops we have is something to stop
"flatspotting after vehicle is parked for extended periods"

speeds on certain stretches of highways. I only notice this in cars with sport suspension and performance tires, not SUV's. On the east coast, many highways that I have traveled on have stretches of subtle "bumps" equally spaced, probably because road engineers and building equipment is sub-par. My opinion is that in general US roads, at least on the east coast, suck.

Its very likely that the roads are causing some of the vibrations, but a good brand of tires will not vibrate even on the worst of the midwest and eastern US highways. Michelins are the best for low profile tires. Avoid Dunlops, Brigestones, and COntinentals due to their poor quality control leading to certain tires with vibration that cannot be solve even by simple road force balancing machines.
