Owner-reported

2003 GMC Sierra mileage at failure

158 of the 207 complaints on file for the 2003 GMC Sierra give the vehicle's mileage when the problem happened.

Mileage at failure by component, from owners' complaints to NHTSA
Component	Median	Middle half	Based on
Service Brakes	Median 80,000 miles	Middle half 45,000–105,000 miles	Based on 75 complaints

A component's median is its 50th percentile, and its middle half runs from its 25th to its 75th percentile.

Owners give the mileage themselves, often as a round number, and NHTSA doesn't check it. A complaint that names several components counts under each one, and mileages that can't be right, such as 999,999, or 50 miles on a five-year-old car, are left out.

These figures describe the complaints owners filed. They don't predict when a particular vehicle will have a problem, and vehicles that never had one aren't counted.

Mileage from NHTSA's complaints file of October 31, 2026. How these figures are worked out

SEAT BELT ROUTING

NHTSA #05V163000 · Seat Belts — Rear/Other · NHTSA notice

Reported April 22, 2005 · GENERAL MOTORS CORP.

Potentially affected: 1,359,824 vehicles

Manufacturer campaign 05037 · Owners notified July 21, 2005 · Vehicles built April 3, 2002 – July 31, 2003 (per NHTSA)

Defect description

ON CERTAIN CREW CAB PICKUP TRUCKS AND SPORT UTILITY VEHICLES, THE 2ND ROW CENTER OCCUPANT SEAT BELT ROUTING MAY MAKE IT DIFFICULT TO POSITION THE LAP PORTION OF THE SAFETY BELT LOW AROUND THE HIPS OF OCCUPANTS, ESPECIALLY SMALLER OCCUPANTS, SEATED IN THIS POSITION. APPROPRIATE USE OF A CHILD SEAT OR BOOSTER SEAT, AS RECOMMENDED FOR SMALL CHILDREN, DOES IMPROVE THE FIT CONDITION FOR THIS USER GROUP. IN ADDITION TO INSTRUCTIONS ON PROPER INFANT AND YOUNG CHILD RESTRAINT (WITH CHILD SEATS OR BOOSTERS), SPECIAL VERBIAGE FOR RESTRAINING OLDER CHILD IS INCLUDED IN THE OWNER'S MANUAL. ALSO, THE SUGGESTED SEAT BELT FIT/ROUTING FOR ADULTS, IRRESPECTIVE OF SEATING POSITION, IS DESCRIBED IN THE OWNER'S MANUAL TEXT.

Safety consequence

A LAP PORTION OF THE SEAT BELT ROUTING THAT IS NOT LOW AND SNUG ON THE HIPS CAN ALLOW THE LAP BELT TO RIDE UP ON AN OCCUPANT'S ABDOMEN INSTEAD OF FITTING LOW AROUND THEIR HIPBONES, AND THEREFORE, CAN EXPOSE THEM TO MORE RISK OF ABDOMINAL AND INTERNAL ORGAN INJURY.

Manufacturer remedy

DEALERS WILL CUT OPEN THE GUIDE LOOP, REMOVE A PORTION OF THE LOOP, AND THEN THE REMAINING TWO SIDES SHOULD BE FOLDED OVER AND SECURED WITH A RETAINER FREE OF CHARGE. THE RECALL BEGAN ON JULY 21, 2005. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, OR HUMMER AT 1-800-732-5493.
