From 3 series to new '08 G35x - Brakes not smooth
#16
Latest Update
I went to the dealer and asked them about the vibraiton. They think taht it may be a tire issue resulting from driving my 325xi with Michelin MXV4 tires on a 16 inch rim. The g35 has a larger rim (17), thinner tire, and is more of a performaocne feel/ride. Perhaps a bit less luxurious ride.
I may actaully think that this may be a big part of teh problem. I thought the vibration was a time/on and off problem, but now i think it may be a place problem, tied to the surface of the road. smooth asphalut it doesnt seem to happen on. Rougher gritty roads its more pronounced.
I am going back tongiht to test drive a new 08 g35X and compare on teh same roads to how my car feels. I also set up an appt just in case for next week with teh dealer.

didn't get to the dealer tonight. but they said that tell tell sign of warped rotors usually result in vibration in the steering wheel or seat back. I have neither issue. but it sounds like some of you do.
moreover, they said that they have seen cars just coming off the delivery truck with warped rotors, never even having been driven.

My 08 G35s sedan had similar vibration from 30-70MPH, and this with only 63 miles on the car. Took it back to the dealer the next day since compared to my former car I had driven up until G delivery (05 M3 cabrio), the brakes felt very rough. Well, they said the front rotors were warped. Don't know if Nissan got a bad batch and didn't catch in QC, or if these can warp on the boat or on the lot? Anyway, they didn't have any new in stock or they would have replaced, but the machined them and he said very little material was removed, and now they are silky smooth. He said if I had any other issues to come back and they'd replace with new. Do you see the need to do that?
Anyway, yep, have them check for warped rotors.

How many miles do you have on the car?
For the first few days my brake pedal did feel a little rough - I guess you could say grinding, but I'm pretty sure its just breaking in the car. When you break in a car, its not just the engine - you have to break in the pads, rotors, and suspension parts since they all are brand spankin new!
The pads and rotors need some time to get used to each other ( ) and they need to get a little scuffed up before everything smooths out.

I also moved from a 330i to a G35x, and the I didn't have any problem with the brakes. They are about the same with the G's being maybe slightly more touchy. I did have a vibration coming through the steering wheel at 11000 miles, and that turned out to be warped rotors - was covered under warranty along with break pads.
