I just bought a 2013 G37x Coupe and the same thing. In the summer, everything was fine, now that the weather has changed with a little snow and colder temperatures, the SQUEAL in reverse is almost unbearable. The neghbours are complaining. The thing that troubles me, is why only in reverse?? Going forward there is a few faint squeal the first couple of applications but than nothing.cjs37xs wrote: ↑Fri Jan 21, 2011 9:22 amMine does that as well in the colder weather. It will squeak when I am leaving the lot here at work, and then after it has gone a few miles no more squeaky. I have had the car since new, and I haven't lost much sleep over it...since it goes away after the moisture (ie: humidity) gets off the rotor surface within a couple minutes.
Doesn't hurt to have them looked at though....costs nothing.
