1984 Mercury Cougar Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

VERY RECENTLY I FOUND THAT THE NHTSA HAS BEEN INVESTIGATING PROBLEMS WITH MANY FORD VEHICLES FROM THE 80'S, DUE TO STALLING PROBLEMS. I OWNED A 1984 MERCURY COUGAR FOR 2 YEARS AND PUT THOUSANDS OF DOLLARS INTO THIS VEHICHLE WITH NO SUCCESS. I KEPT ALL MY RECEIPTS KNOWING THAT SOME DAY THE PROBLEM WOULD COME OUT. I WISH TO BE PART OF THESE COMPLAINTS AGAINST FORD AND HOPES OF GETTING MONEY BACK DUE TO FORDS MISTAKE WHEN ASSEMBLING THE VEHICLES. THE MERCURY COUGAR STARTED STALLING ALMOST IMMEDIATELY, BUT GOT WORSE AS TIME WENT ON. DATES INVOLVED REPAIRS WERE FROM JANUARY OF 1989 UP TO APRIL OF 1990. FINALLY IN AUGUST OF 1990 I TRADED THE VEHICLE IN, AFTER MANY SITUATIONS OF ALMOST BAD ACCIDENTS DUE TO THE VEHICLE STALLING WHEN STOPPING OR JUST DRIVING DOWN THE ROAD. THE VEHICHLE WOULD JUST SHUT OFF AND IT WOULD TAKE NUMOROUS TRIES TO GET IT STARTED OR I WOULD HAVE TO GET IT TOWED. THE STRESS AND CONCERN OF MY TWO YOUNG CHILDREN WAS MORE THAN I COULD HANDLE. I FEEL FORD MOTOR COMPANY SHOULD TAKE RESPONSIBILITY IN ALL THERE MISTAKES. NO MATTER WHAT IT COSTS, TOO MANY PEOPLE HAVE LOST LIVES DUE TO THIS ENORMOUS COMPANY. *AK
