Engine Cooling System problems of the 2007 Ford Focus

In 2007, I purchased my new Ford Focus based on the recommended rating in consumer reports. Did you know that when the a/c of the Focus stops functioning, so does the auto? I am not mechanically inclined. I don't know if most or all autos are built this way. If so, based on the difficulties I have had just to find out this fact about Focus, and the $1,400 expense I incurred fixing problems, I would strongly suggest that this fact clearly stated in any ratings discussion, in bold fonts. My car had been maintained at the dealer every 3,000 miles, has only 42,000 miles on it, without accidents, tickets, violations. Foremost, the a/c should have lasted much longer. I am not sure that the recommended rating was warranted.

Have 2007 Ford Focus se with 50,000mil on it. 1st offense happened July 2009. Had to replace 100,000 mil warranty spark plugs(Ford product) @ 38,000 mil. They were burnt to crisp . Replaced then 2 wks later btwn 45-50 an hr my car was shifting like a manual transmission. I was told I no longer had a warranty(Ford directly said this) went to another rep company. Told me my cylinders were going out. No engine light was coming on. Company told me to call Ford directly because maybe there was a recall. They told me there wasn't and that I did have a powertrain warranty but this was not covered,yet my owners manual says that cylinders are covered by powertrain. I paid over $200 to fix problems in Aug 2009. It is now oct 2009 and I will have to replace everything again! I am to this date barely over 2 yrs old on the vehicle(bought Aug 2007) and just now turned over 50,000 mil. This should not be happening to this vehicle. The company I took it too said that they see this problem alot because the cylinders get too hot and burn the spark plugs because there is no cooling system for this area. This needs to be a recall.
