What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2000 Mercury 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.

THE REAR CENTER SEAT BELT OF MY 2000 MERCURY GRAND MARQUE IS DEFECTIVE. WHEN A CHILD SEAT IS BELTED THERE, THE SEAT BELT STRAP GRADUALLY SLIDES LOOSE THROUGH THE LOCKING DEVICE. THE SEAT BELT APPEARS SECURE AT FIRST, BUT IT GRADUALLY LOOSENS AS THE WEIGHT OF THE CHILD SEAT ROCKS AGAINST IT. THE BELT LOOSENED COMPLETELY AFTER 30 MINUTES OF DRIVING, AND WOULD HAVE BEEN USELESS IN A CRASH. FORTUNATELY, WE DISCOVERED THE PROBLEM BEFORE ANYONE WAS HURT. WE WENT TO DUDDIE FORD OF NORTHBOROUGH, MA ON 1/29/03 AND PRESENTED THE PROBLEM.
HEADREST DOES NOT PULL UP HIGH ENOUGH TO BE PLACED BEHIND HEAD, IT WILL ONLY REACH TO THE BASE OF THE SKULL. CONSUMER FEELS THIS IS UNSAFE BECAUSE HEADREST MUST BE DIRECTLY BEHIND HEAD, NOT THE NECK. *AK THE CONSUMER STATED THAT; PER OWNERS MANUAL, THE HEAD RESTRAINT IS TO BE PROPERLY ADJUSTED BY LIFTING THE HEAD RESTRAINT SO THAT IT IS LOCATED DIRECTLY BEHIND YOUR HEAD. *SCC
