What owners say

I am the original owner of a 1999 mercury cougar automatic v6. I have never been in an accident with the vehicle, but continue to have mechanical problems. Like other 1999 ' 2000 mercury cougar owners I worry about the safety of driving a vehicle with more problems than can cost effectively be fixed. My list of broken items include the radio, power window regulator, o2 sensors, transmission at 59,000 miles, dashboard lights (low coolant and check engine), door/window leaky seal issues, engine misfire (decreased acceleration) and now my cruise control and turn signals do not work. Upon researching the recall for cruise control fires dealing with ford products I found that I am among other disgruntled cougar owners. Ford/mercury or ford technicians have not done a satisfactory job letting owners know of recalls that need attention. My latest concern is that my cougar might start on fire, per my complaint with ford; they see no threat with my cruise control issues and suggested I contact the federal safety agency with my complaint.
