What owners wrote

1. Car began to lose power and the steering wheel began to lock up and lights began flickering on the dash. 2. The car stalled in the fast lane on a busy freeway. The consequence was a small truck rear-ended the back of the car and it was totaled. One person had busted lip in truck and one in the car had busted forehead and blackened eyes with back injuries and the other one had back and stomach extreme pains and legs. 3. Nothing could be done at this point-the car always had problems.

June 2006 CrashInjury

My car is a lemon. Have had a new engine put in it 2 times because the rods spun. I have had the brake lights "fixed" 3 times, the alternator replaced 3 times, new catalytic converters twice. New power steering. Transmission done 3 times. Theres definantly more I just cant think of alllllll my repairs on this 1999 cougar. I bought it used and it has now 98000 miles cause I drive out of state.
