It could be a safety issue. Do they know this?
By the way, the pedal isn't getting trapped by a mat is it, or a bit of loose trim under the steering column? I'm sure it isn't as you must have wondered about this, but I just thought I'd mention it.
And have you ever been with your wife when it happened, or been out with her for a long drive to see exactly what is going on?
My car, second hand from a dealer, came with a poor door seal that made the car very noisy above 55/70 mph. My suspicion is that the previous owner never drove quickly and anyway probably didn't care anyway. It was slight with a tailwind and truly awful with a sidewind, the draught inside was palpable. The dealer took my complaint on trust, had a good look at the seal with me present and suggested re-hanging the door, which they did within the hour - job done - no noise. I was impressed as they didn't treat me like a fool, listened to me and accepted what I told them without insisting on a drive in the car. I'm happy with my dealer but I know full well that if I wasn't I'd not buy another car from them.
I would give it a last check yourself and then go to the dealer and tell them that this could be a safety issue. That might encourage them to do the job properly. Otherwise refuse the car and let them make an issue out of it.
