Nine months old, 12,000 miles, suddenly a LOUD grinding noise (sounds like driving over the strips on the side of the freeway that are there to wake people up who fall asleep) with right OR left turn with slight change going up or down into parking lot, etc. The dealer finds nothing, tells me it's the ABS and "perfectly normal". Funny it didn't do it the first nine months, and my friend's MDX doesn't do it either. They've had it two days now with no luck. Anybody with similar experience?
