2007 Chevrolet Trailblazer 360 problems

General information about Chevrolet-Trailblazer 360
Overview of popular issues

The Chevrolet TrailBlazer (also known as Trailblazer) is a mid-size SUV produced by Chevrolet, a division of General Motors. The nameplate was first used in North America from 2001 to 2008; in 2009, it was replaced by the Traverse, as a crossover SUV. In 2011, production of a newly-redesigned version of the Trailblazer for the Asian and Brazilian markets began.

Blazer trim line (1998)

The TrailBlazer name was first introduced for the 1999 model year as an upscale trim level of the compact 4-door Chevrolet S-10 Blazer. It offered additional features on top of the previously top-of-the-line Chevrolet S-10 Blazer LT trim level, including an AM/FM stereo with single-disc CD player and optional remote cassette player, OnStar, color-keyed front and rear bumpers, side cladding, a leather-wrapped steering wheel, upgraded alloy wheels, a full-size spare tire and wheel, and upgraded cloth seating surfaces with power front bucket seats. Options such as a Bose premium sound system, leather-trimmed seating surfaces with heated front seats, power sunroof, and gold accents for the exterior emblems were all available for the original TrailBlazer trim package. The TrailBlazer trim was discontinued after 2001, when an all-new TrailBlazer model was introduced as a mid-size SUV. Production of the S-10 Blazer overlapped until the 2005 model year.

First generation (KC; 2001)

The first-generation TrailBlazer is based on a truck platform officially known as GMT360, with all models having four-wheel-drive layout as an option with both automatic engagement and the more traditional "Auto," "2-High," "4-High," and "4-Low" gearings, except the SS model which features an all-wheel-drive system. The TrailBlazer features an independent front suspension, and a five-link rear suspension. A G80 locking rear differential is available as an option on all models except for the SS, which has a G86 LSD as standard. An LTZ trim level had upgraded interior features (leather), upgraded sound system (Bose), and alloy wheels. All TrailBlazers came factory-equipped with a detachable towing hitch.

The TrailBlazer was updated in 2005 for the 2006 model year. An updated front fascia on all models (except for the base version) and new interior trim were included with the refresh. The SS received trim-specific front and rear fascias plus color-matched side skirts.

Common 2007 Chevrolet Trailblazer 360 problems

The 2007 Chevrolet Trailblazer 360 has been reported to have several common problems based on complaints from owners.

Electrical Short: A recall was issued for 2006-2007 Chevrolet Trailblazers due to a potential water leak in the driver's side door that could cause a short in the driver's side electrical panel module. This issue could cause intermittent or non-operation of the power door lock and power window switches, and an electrical short could cause odor, smoke, or fire.

Charging System Issues: Some owners have reported that their Trailblazer is not charging. This issue could be caused by a problem with the Generator Battery Control Module (GBCM) or the PCM. The Generator Turn On Signal (GTOS) sits at 2V engine on, which is lower than the required 3.7V, indicating a problem with the charging system.

Brake Problems: The Trailblazer's brake system has some intricacies that technicians should be aware of. The front brakes utilize dual piston calipers with phenolic pistons, and the most critical hardware item is the pad retention clip inside the caliper’s bridge. The rear brakes use a single piston caliper with the parking/emergency brake in the hat. Pad replacement is straight forward, but rotor replacement can be difficult and may require a slide hammer with a right attachment. The parking brake shoe and the clips that hold it to the backing plate should be inspected for any signs of the friction material delaminating or cracking.

These are some of the common problems reported by owners of the 2007 Chevrolet Trailblazer 360. It is essential to address these issues promptly to ensure the safety and reliability of the vehicle.
