The 2005 Chevrolet Trailblazer is the worst model year with the most complaints, suffering from engine failures related to the 4.2L inline-6 cylinder, electrical system problems, and fan clutch failures that caused overheating. The 2002-2006 models share many of these issues, with the 4.2L engine prone to coolant leaks, timing chain problems, and oil pressure issues. The transfer case in 4WD models was weak and prone to failure. The 88 deaths reflect the SUVs rollover risk during emergency maneuvers and various crash-related incidents during the mid-2000s SUV safety concerns.
