“I have always had my car washed and rust proofed during the winter ever 2 weeks. Last december the paint under the bottom of both the drivers and passenger doors started having the paint bubble up on both rocker panels. It started bubbling up then curling and the pain started coming off. Ive seen many other cougars with this same problem and feel it is due to a defect in the paint that was used or something missing from the paint job that was done”

I had no lights , I had no tail lights,no head lights ,no blinkers and no emergency lights and the car close behind me had to slam on breaks cause there was no emergency lane, no side of the road just a guard rail! I was in the middle of the road . …”

NHTSA complaint #743999, filed 2001-04“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. …”
