Within that volume, owners reported 0 crashes, 0 fires, 1 injury, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2003 MOUNTAINEER is latches/locks/linkages:hatchback/liftgate:lock with 1 filings, followed by suspension:rear (1) and service brakes, hydraulic:antilock/traction control/electronic limited slip (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 1 active recall campaign, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 177 investigation files overlapping the 2003 MOUNTAINEER, and 8 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

ABS LIGHT COMES ON AND GOES OFF. BRAKES ARE STARTING TO FAIL WHEN LIGHT IS OFF, NOT WHEN THE ABS LIGHT IS ON. I AM GOING TO TAKE IT TO THE DEALERSHIP FOR INSPECTION.*AK

2003 MERCURY MOUNTAINEER HAS REAR DIFFERENTIAL ISSUES. LOUD HUMMING COMING FROM BACK END. POTENTIAL FAILURE IS POSSIBLE AT ANYTIME WHICH CAN RESULT IN LOCKING OF BACK WHEEL.
MY 2003 MERCURY MOUNTAINEER HAD A LIFT GATE RECALL. LINCOLN MERCURY DEALER IN HYANNIS, MA REPLACED PARTS TO FIX. THIS WAS LAST YEAR. THIS WEEK THE LATCH BROKE ON THE OUTSIDE OF THE WINDOW AND THE GLASS FELL AGAIN. LINCOLN MERCURY DEALER IN HYANNIS CHARGED ME FOR THE PART! THIS ALL IS DIRECTLY RELATED TO THE EARLIER RECALL I WOULD BELIEVE. THE DEALER SAYS NO. THE ORIGINAL RECALL SAID LIFTGATE GLASS STRUT MAY DISENGAGE OR HINGE MAY FRACTURE, ALLOWING GLASS TO FALL AND POSSIBLY BREAK. AM I WRONG? AND IF IT NOT PART OF THE RECALL THEN I GUESS IT SHOULD BE. THANK YOU VERY MUCH FOR YOUR TIME.
