Chevrolet Trailblazer 360 Years to Avoid
The 2007 TrailBlazer 360 accumulated the most complaints, with engine and electrical issues leading concerns. The 4.2L Atlas inline-6 had timing chain and oil consumption problems on some examples. The 2007 models experienced fan clutch failures that led to overheating. Electrical gremlins affected the instrument cluster and power accessories. The 2006-2007 models had more transmission concerns than later years. Water pump failures were common around 80,000 miles.
Best Chevrolet Trailblazer 360 Years
The 2009 TrailBlazer 360, as the final model year, benefits from all accumulated improvements. The 2008 models also show fewer complaints than earlier years. The 5.3L V8 option is more reliable than the inline-6 for those wanting more power. A late-model V8 TrailBlazer offers the best reliability.
