“My 2006 Toyota Avalon had a sudden loss of all my oil from a ruptured oil line while I was driving home from the store 2 miles away. Apparently Toyota knew about this problem based on other numerous similar incidents based on web comments. The oil warning light never went on and I never received a recall notice about this problem which was sent to other Avalon owners.”
