1989 Mercury Grand Marquis 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.

What this page shows

Everything below is an owner-reported complaint submitted to NHTSA about the 1989 Mercury Grand Marquis, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.

Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

FUEL LINE RUSTED OUT AND LEAKED GASOLINE ONTO PAVEMENT, UNDER DRIVER'S SEAT. THIS EVENT WAS NOT CAUSED BY AN ACCIDENT, AND DID NOT CAUSE AN ACCIDENT. THIS EVENT DID CREATE A FIRE HAZARD, BUT IT WAS CAUGHT IN TIME. MY CAR IS IN THE DEALER'S REPAIR SHOP 13+ DAYS NOW AND STILL AWAITING REPAIR, BECAUSE THE MANUFACTURER (FORD) HAS THE NEW FUEL LINE PART ON "NATIONAL BACK ORDER" AND REFUSES TO FULFILL MY DEALER'S ORDER FOR A NEW PART. PLEASE HELP ME GET MY CAR FIXED. PLEASE NOTE ALSO THAT THIS SAME CAR MODEL WAS INVOLVED IN A PRIOR MANDATORY RECALL IN 1996 FOR A FAULTY IGNITION SWITCH CAUSING A FIRE IN THE STEERING COLUMN, AND THIS SAME CAR WAS ONE OF THE CARS REPORTED TO YOU THAT HAD ACTUALLY CAUGHT ON FIRE. FORD REFUSES TO RECALL THIS CAR. I THINK ANOTHER MANDATORY RECALL FOR THIS NEW PROBLEM IS NEEDED NOW.
