We've updated our reliability stats for the TrailBlazer and other GMT360s (all combined in the stats below) to include owner experiences through the end of 2015, about eight months ahead of other sources. In terms of repair trips per 100 cars per year--lower is better:

2008 TrailBlazer: 76, moderate
2007 TrailBlazer: 64, moderate, small sample size
2006 TrailBlazer: 98, high
2005 TrailBlazer: 81, moderate, small sample size
2004 TrailBlazer: 98, moderate, small sample size
2003 TrailBlazer: 73, low, small sample size
2002 TrailBlazer: 86, moderate, small sample size

No stat, or a small sample size? Then we especially need more owners involved for that model year.

p410&p136 codes

i just bought a 2004 trailblazer 4x4 I6 enine codes 410 and 136 come on . I have checked the hose from air cleaner to the joint fitting that is by firewall. That hose on cold starts seems to suck very little. Truck running always sounds like a diesel is this normal!! The codes have come off once before. i found a cracked hose from the air cleaner to the joint fitting!? i disconnected hose from the air valve and seems to suck on cold start up. but not so strongly?! im not really educated or wise enough to use a multitester to check the voltage to the air valve or any other . ! When exiting highway lights dim when coming to a stop . doesnt loop on idle or chug on accleration. did not notice if idle speed changed on exitramp.
