My only suggestion, and something I just tried fo ryou is the NHTSA records. Hwever, their site was being incredibly frustrating. However they track patterns in vehilce incidents and reports which can eventually lead to involuntary manufacturer recalls, etc.
I personally have been skepticl of the drive by wire systems. To me, it' no different than the steering wheel and pedals I have for my videogame systems, and even that does not always respond to the movement I selected.
Also, this is a main reason why when a new car, or redesign comes out, or new technology in thsi case, I always sit back and watch for a few years for pattern problems before I'd even think about buying the vehicle or recommending it, 5th Gen might be a different story tho
