Car moves front and back at braking.

I noticed from the very first day that after I stop my G6 it lurches forward a bit and then back. I still had my old car which was an Olds Alero, and when I put on the brakes it didn't react that way. Someone suggested to me that it might be a warped rotor. Any ideas on this before I take it back to the dealer?

Can you feel it in the pedal? If so I would say a definate rotor problem.

I know the exact feeling you are talking about. Havent experienced it in the G6 but I have in my former 02 Grand Am. Thats a sign of warped rotors.

Warped rotors is covered ususally. It can be caused by lots of things. GM vehicles are more likely to develop rotor problems vs the majority because they are usually smaller than they should be, and usually made cheaper than aftermarket. It can also be caused by excessive brake, riding the brake, brake overheating, and hard braking. Usually if you get a decent set of aftermarket rotors the problem is a lot less common.

My G6 does the same thing, move front and back when stopping. Is this somethin that alot of G6 owners are finding?

Thank you for all of your responses. You are all describing what I am experiencing. I took my car to the dealer's service department and he said there was nothing wrong, but it was just the normal suspension. I don't believe it and I still think the rotor is warped. I am persistent and I will try again.

I have the same prob with my G6. It sounds like air comming out of the shocks or something. does anybody know if it is normal or is anybody have this prob. Its a prob that goes allong with the car moving back and forth when I stop. They are the only two things that I see rong with it.

Well, if it helps....I don't notice the lurch forward and back when stopping and I don't notice the noise like air coming out of my shocks when I hit bumps. Maybe they are related. I have around 5000 miles on my G6 base.

I've got the suspension noise coming from the right front. Sounds like something is loose. Had the same problem with a '98 Malibu. Shouldn't be happening on a vehicle with only 2000 miles on it. I know I live in Michigan and our roads are bad, but....

Ralphy is it a rattle noise? When I hit bumps I have something outside the car on the passenger side that makes a rattle noise. Drives me nuts.

My brakes do the same exact thing. Forget trying to brake at highway speeds. Rotors are definately screwed.
