LV Focus XR5 - ABS and DSC Failure Questions

[Skid Marx]

Dear Knowledgeable Focusters, advice or comments on the following would be appreciated by this slightly shocked owner.

Situation:- Purchased new 2010 LV XR5 in May. Had it's 3000k 'inspection' - no faults. Driven on smooth roads, no big pot-holes or any undue wheel torture.

Problem:- Having done only 4600ks over the past week I noticed that every morning when arriving at work, I'd have to turn hard right (slowly) to fit into parking space and noticed a sort of low vibration sound similar to disc squeal only lower. Thought nothing of it at first but noticed an accompanying grinding sound towards the end of the week. A quick look at the rotors didn't reveal any scoring or signs that the pads were made of granite etc. Besides, braking at all other times was silent and smooth.

Friday morning (today) extra noticeable grinding sound when hard right turn to park. So, before driving home tonight, I waited 'til the carpark was pretty emprty so I could deliberately try to 'bring it on'. Whatever was going to happen I wanted it to happen there rather than on a busy road. So I turned hard right and drove in circles applying the brakes regularly. Horrible grinding sound from front wheel(s) and brake pedal feels like it's pressed against a rapidly boiling tank with a low rumbling feel.

Now both the ABS and DSC (stability control) warning lights come on even though I'm doing 15ks/hour in a flat dry carpark. Brakes still work fine however I can't change up beyond 4th gear. 5th and 6th seem to be blocked out. Can still get into reverse though.

My main question then is:- is this normal for the higher gears to be blocked out when it's stability system is knackered? I was sure I read about this somewhere in the manual when I got it new, but I can't find it anywhere now. Also, is it a fairly quick item for Ford to replace? It's surely a warranty job, but I'm wondering if this is a common problem with the LV Focus?
