I posted this a while back, but no solution was found, so I'll try again...
At the rear of the MDX, a small amount of oil drips from the bolt that hangs at the center of the spare tire. Just enough oil for a drop the size of a dime. Doesn't happen all the time, but quite frequently.
Dealer said it was from lubricant used on the spare tire cable. They cleaned it off, but the leak is still there.
Hey, we've had the MDX for 4 months and I *just* noticed the spare tire cable oil drip (or so I think, it is frankly so small it could have been from that pizza box that was under the car )
