Some of the recalls announced for the Chevy Trailblazer include the recall for 2006 to 2007 models in 2013 due to fire risk and recall for 2005 to 2007 makes in July 2014 due to faulty driver's door module. The latest recall in December 2014 addressed a headlamp problem.
The earliest recall that General Motors announced for the Chevy Trailblazer was for the faulty front lower control arm brackets that may cause a loss of vehicle control and result in a vehicle crash. Other recall announcements throughout its production years addressed issues such as non-NHTSA compliant seatbelt assembly, key ignition issues and faulty driver's air bag and windshield.
When a specific car model and year has been found to be faulty, the manufacturer or the National Highway Traffic Safety Control orders a recall of the affected vehicles. The automaker releases a press release and mails the owner of the affected vehicles. The car owners do not have to pay for any repair cost as the manufacturer repairs or replaces the faulty component free of charge.
Not all car defects warrant a massive car recall. In 2011, the owners complained about the faulty fuel gauges on the 2005 to 2007 Chevy Trailblazers. After the NHTSA started an investigation, GM agreed to pay for the repair of the faulty gauges, but the automaker did not announce a recall for the affected cars.
