Owner-reported

2004 Chevrolet Trailblazer EXT mileage at failure

212 of the 260 complaints on file for the 2004 Chevrolet Trailblazer EXT give the vehicle's mileage when the problem happened.

Mileage at failure by component, from owners' complaints to NHTSA
Electrical SystemMedian 65,000 milesMiddle half 45,000–85,000 milesBased on 122 complaints
Fuel/Propulsion SystemMedian 80,000 milesMiddle half 55,000–100,000 milesBased on 38 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.

GM/BRAKE LAMP FAILURE

NHTSA #04V527000 · Exterior Lighting — Brake Lights · NHTSA notice

Reported November 1, 2004 · GENERAL MOTORS CORP.

Potentially affected: 871,473 vehicles

Manufacturer campaign 04087 · Owners notified November 22, 2004 · Vehicles built April 1, 2003 – August 31, 2003 (per NHTSA) · Recall influenced by NHTSA's Office of Defects Investigation

Defect description

ON CERTAIN SPORT UTILITY VEHICLES, VIBRATION AND HEAT MAY CAUSE THE TAIL LAMP/STOP LAMP BULB TO LOOSEN IN ITS SOCKET. IF THIS OCCURS, THE BULB MAY FLICKER AND EVENTUALLY BECOME INOPERATIVE.

Safety consequence

AN INOPERATIVE BRAKE LAMP WILL NOT CONVEY THE DRIVER'S INTENTION OF STOPPING TO DRIVERS IN FOLLOWING VEHICLES, AND AN INOPERATIVE REAR TURN SIGNAL LAMP WILL NOT CONVEY THE DRIVER'S INTENTION TO TURN TO DRIVERS IN FOLLOWING VEHICLES. BOTH OF THESE FAILURES CAN INCREASE THE RISK OF A CRASH.

Manufacturer remedy

DEALERS WILL INSPECT THE TAIL LAMP/STOP LAMP ASSEMBLIES, AND IF NECESSARY, REPLACE THEM. THE RECALL BEGAN ON NOVEMBER 22, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438, OLDSMOBILE AT 1-800-630-6537, BUICK AT 1-866-608-8080, OR GMC AT 1-866-996-9463.
