The issue over the summer affected AWD models. The problem was a vibration in the transfer case when driven at low speeds (as in parking lots). There was very little concern over drivability but production was halted for two months until Magna Drivetrain corrected the problem. AWD production at Brampton was stopped in June and resumed late (very late) August. It has since all been corrected and orders are being filled.
I had placed my order in May (I was the second one to place an '06 order at that dealer). After waiting for over two months I started digging into the reasons for the delay and became more patient after understanding the issue. I spent too much time researching my next vehicle purchase to bail on my order. Finally, I received word in September that my car was well underway being built. After the excrutiating wait, my car was delivered November 2. It is beautiful: 2006 300C AWD Silver Steel w/ Dark Slate Grey interior. Well worth the wait. I love it.
Anyhow, an AWD order shouldn't take more than 8 weeks now. Keep your eyes peeled. Chrysler will be offering 2 years of fuel in place of incentives. Of course, per usual, it probably won't apply to a 300 because they are selling so well.
