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 1990 Mercury Grand Marquis, grouped by the component NHTSA recorded on the report.

WITH MY FOOT ON THE BRAKE, I ENGAGED THE SHIFT LEVER INTO THE R POSITION WHICH RESULTED IN IMMEDIATE ACCELLERATION IN A REVERSE DIRECTION. I SWERVED THE CAR TO THE LEFT TO AVOID CHILDREN ACROSS THE STREET AND RAMMED A VEHICLE PARKED ON THE STREET. THE VEHICLE STOPPED ON IMPACT WITH THE OTHER VEHICLE AND RETURNED TO NORMAL IDLE SPEED. I PLACE THE CAR IN D AND RETURNED IT TO THE DRIVEWAY WHERE IT REMAINED UNTIL WE COULD DELIVER IT TO OUR FAMILY MECHANIC.
