Defect
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.

“Rusted brake line”
“Gmc replaced all 8 fuel injectors under warranty at 95,000 miles. Same problem again at 135,000 and will not cover them. Estimated $5,500 to replace by consumer with only a 12 month warranty. Creates poor fuel economy, excessive smoke at idle and will not pass smog if not corrected.”
“I experienced a brake line failure on my 2004 gmc sierra crew cab pickup truck. I was traveling at a slow rate of speed and coming up to a traffic light and the brake pedal pushed all the way to the floor board. The rear emergency brake was used to stop the vehicle. I found the area around the…”
