X2 on the floormats not being the problem, looks like an excuse before now. Believe it is a problem in the fly by wire/computer control system from things I've been reading. Also seems the fix is a brake override of the system that many other brands allready incorperate in their systems. Tragic for those that have lost lives due to this failure. We recently had a fatal acceleration at a T intersection into a pond, that at first was blamed on the mat, until it was discovered locked in the trunk. Unfourtunatly, the black boxs don't record these failures, as it seems to be part of the problem.
