Is that what they are trying to resolve? I have the same problem on my 09 CTTS but it usually disappears by the time I reach the dealership. It is very annoying.

Exactly (squeal after release) and exactly (impossible to reproduce around anyone who works for Porsche). Apparently the repair kits are on the way so one of us should know something soon.

I'm sure it's going to take a bit for them to get all of the parts and my dealership said they will call everyone that has complained about this in the past and get everyone fixed.

It makes you wonder what condition our rotors and pads are in, doesn't it? 15K mile pad/rotor life will make me unhappy.

I have the same squealing noise when releasing the breaks. It really annoying, but i can't duplicate the noise when taking the car to dealership.

I finally took the CTTS for the brake fix. Apparently there a bulletin describing that the calipers do not release, causing a squealing noise once you let off the brake pedal and start moving. The tech stated he needs to take apart the calipers and lubricate the pistons. Considering the mileage, the rotors are significantly worn (from the calipers not releasing) so hopefully Porsche will replace those too.

Here is the update. The brake calipers were removed; the pistons were taken apart, cleaned, and lubricated. Front and rear pads and rotors were all replaced. Everything was covered under warranty.

We had a regular Cayenne loaner, which was nice but the CTTS sure has a bit more power.
