Complaint Review: Ford Mac Haik

I bought a ford expedition 2006 from Mac Haik in Georgetown tx in 2006, We went to change $ 12.00 park plugs the forth one on the driverside broke ,now the cost for a $12.00 plug is $3,051.00 to get my car up and running, Ford knows of the problem but will not be responsible for the bad design of the plug.. I have my car at the shop in Taylor tx covert ford and have to come up with this money in order to get my car fixed.WOW We have 4 fords and will never buy another.. This is a big rip off, you would think they would make things right by their customers They act like they know nothing about it. But it's all over the Internet.. Class Action suite ..I hope they make things right by Ford Buyers.
