Just got a notice last week from Ford Motor Co saying they had extended the warranty on their 2000-2003 model Focuses for the coil springs (up to 10 years or 150k miles). Apparently the corrosion protection was inadequately applied on many vehicles causing the spring to actually fracture (normally a very rare occurrence).
This only caught my eye because just last month I had to shell out over $300 to have one of the springs on my 2001 Focus replaced because it had fractured. I called the dealer and they said it wouldn't be a problem to get a refund (just bring the receipt). Phew!
