Exactly what failed

NHTSA files every complaint against a named sub-assembly, not just a system. This is the difference between knowing it was "the engine" and knowing which part of it — the list to hand a mechanic.

Instrument Cluster/Panel 171 55.9%
Headlights 32 10.5%
Fuel Gauge System 30 9.8%
Automatic Transmission 23 7.5%
Body 15 4.9%

Power Window Devices AND Controls 12 3.9%

When it fails

Odometer readings owners gave when they filed. About half of all complaints include one.

When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

NHTSA investigations into the 2005 Chevrolet Trailblazer

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

Recalls on the 2005 Chevrolet Trailblazer

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

AIR BAGS:FRONTAL

CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.

Risk: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.

CERTAIN SPORT UTILITY VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 212, 'WINDSHIELD MOUNTING.' THE WINDSHIELD URETHANE BEAD MAY NOT HAVE ADHERED TO THE BODY IN CERTAIN AREAS DURING THE CURE PROCESS.

Risk: IF A CRASH OCCURS, THE WINDSHIELD MAY NOT BE RETAINED, INCREASING THE RISK OF INJURY TO A VEHICLE OCCUPANT.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2019420 5,327 units in Canada

Other

Issue: This recall is for aftermarket replacement rear window glass produced by Vitro Automotriz. Certain rear window glass may not have been properly tempered. If the window breaks, the glass may separate into large pieces instead of very small ones. Note: This is a voluntary recall that is not being conducted under the requirements of the Motor Vehicle Safety Act. Safety Risk: Glass that breaks in to large pieces could create a risk of injury. Corrective Actions: The company will notify consumers by mail and instruct them to inspect the designation code marked on the rear window glass. Products affected by this recall have the designation “DOT 287” along with the lettering “VMR” (Replacement Market) and a date code that is before July 2019. This information is printed on the bottom corner of the glass. Consumers should contact Vitro's customer service at 1-412-995-6457 or argbacklites@vitro.com to arrange for replacement of the glass.

Recall 2005031 499 units in Canada

Other

Certain vehicles do not comply with the requirements of CMVSS 212 - Windshield Mounting. The windshield urethane bead may not have adhered to the body in certain areas during the cure process. As a result, the windshield may not be retained during a vehicle crash. Correction: Dealers will replace the windshield.

The airbags failed to deploy In a significant collision where hood, radiator, grill/number and both headlights were damaged. GM has been contacted and fail and refuse to do an inspection stating the issue is time barred to 10 years to original warranty of vehicle and are failing to acknowledge manufacturer defect or issue a recall. There were no warning signs/lights prior to notify that the airbags would fail to deploy in an accident.

STRUCTURE:BODY

The contact owns a 2005 Chevrolet Trailblazer. The contact stated while driving 50 MPH with a fully loaded pull behind 6X12 U-Haul trailer hitched to the vehicle on the highway, a tractor trailer drove by at 70 MPH, and the wake turbulence from the tractor trailer caused the U-Haul trailer to fishtail, the vehicle and trailer did a 180-degree skid, spun around, and then jackknifed; causing damages to the U-Haul trailer and the vehicle. There were no injuries sustained. The contact was concerned about the safety of the design of the U-Haul trailer. The contact stated that the U-Hauler trailer was not designed with the proper wheel and axle configuration which caused the trailer to be unsafe while driving over bumps or depressions on the roadway. The contact stated that he was advised by the South Carolina State Patrol to file a Collision Report. The contact had not yet contacted U-Haul to report the failure. The vehicle was still drivable and was driven to the residence. The vehicle was not yet repaired. The vehicle manufacturer was not notified of the failure. The approximate failure mileage was 208,000.
