The seat rocking issue on the C6 is a totally different animal than on the C5. At least mine was. The rocking was occurring on the riser mechanism, and the dealer had to replace the whole riser on mine to fix it.

I'm not aware of any simple "washer" fix for the C6.

What's the best way or test to tell if your C-6 has the rocking seat problem?

Mine rocks when I take off fast at a light in 1st gear. I can't repeat it by sitting and pushing back on the seat, so it's kind of hard to diagnose since it only happens to me when taking off fast.

I haven't done that yet open it full throttle from a stop.

Just discovered mine yesterday. Less than 1500 miles on the car. It's really annoying!!

Yours is a 2009?

No. It's a 2010 Gs. I traded the '09 coupe in November.

Mine is 2005 and haven't had that rocking seat problem.

Which part is this? How do you duplicate this C-6 rocking problem?

If you've never noticed it, you have nothing to worry about. I had my 05 repaired under warranty when it was new and have had no problems since. It was very annoying at the time.

I had it twice with the C5, once on the C6. All fixed. The second C5 repair they covered even though the warranty had expired. I believe the track repair is essentially the same fix for all.

The mechanism that raises and lowers the seat was what caused the rocking seat issue in my C6, not the tracks. The part they ordered was called the "riser". I never got to see the actual part myself, but when I got under the seat and examined what was actually moving, it was the rod with the bar on it that rotates and lifts the seat up and down and is driven by a screw drive. I could duplicate the problem at the dealer by simply sitting in the seat and pushing backwards against the seat like happens when you step on the gas and it would "pop" back and forth. I also found it was more prone to do it with the seat in one position. If you raised or lowered it a bit it would go away for a while, only to come back later.

It hasn't done it at all since they replaced the "riser".

Like dem Vettes

Doesn't it bother Corvette owners that GM cannot even make something as basic as a quality seat?

GM, you can sell all the Malibus you want, but you still do not know how to make a high-end car with quality.

So then what's the test to see if you have this "Rocking Seat" Problem? Push back using your back to see if seat/ seat track moves?

yes !!!

I have had my 2013 for about 3 weeks now and I now have a rocking seat.
