2002 Chevrolet Trailblazer mileage at failure

755 of the 1,145 complaints on file for the 2002 Chevrolet Trailblazer give the vehicle's mileage when the problem happened.

Mileage at failure by component, from owners' complaints to NHTSA
Power TrainMedian 65,000 milesMiddle half 40,000–95,000 milesBased on 249 complaints
Electrical SystemMedian 70,000 milesMiddle half 35,000–130,000 milesBased on 106 complaints
EngineMedian 60,000 milesMiddle half 25,000–90,000 milesBased on 104 complaints
Exterior LightingMedian 55,000 milesMiddle half 25,000–100,000 milesBased on 87 complaints
Fuel/Propulsion SystemMedian 85,000 milesMiddle half 50,000–130,000 milesBased on 91 complaints
Visibility/WiperMedian 45,000 milesMiddle half 20,000–80,000 milesBased on 60 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.

Complaints received before December 15, 2002 rarely give a mileage, so they aren't counted here.

NHTSA defect investigations

NHTSA's investigations file lists the 2002 Chevrolet Trailblazer in 10 investigations. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.

Safety consequence

IF THIS WERE TO OCCUR, THE SAFETY BELT MAY NOT RESTRAIN THE OCCUPANT AS INTENDED DURING A CRASH, AND COULD RESULT IN INJURY TO THE OCCUPANT.

Manufacturer remedy

DEALERS WILL INSPECT THE DRIVER AND FRONT PASSENGER SAFETY BELT RETRACTORS, AND REPLACE THEM IF NECESSARY. OWNER NOTIFICATION BEGAN ON JUNE 24, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, OR OLDSMOBILE AT 1-800-630-6537.
