2006 Chevrolet TrailBlazer EXT LS 4dr SUV 4WD (4.2L 6cyl 4A)
To sum it up I have been trying to give it back since 3 days after I bought it. In one year no exaggeration it has been in the shop at least 50 times. Four times LAST week with another appointment set up for next week. This vehicle is poorly made, maintained, assembled and all around junk.
Don't laugh, it has a great heater and the horn works, thats the only good qualities about it.
Junk the whole line and fire the designers/techs/and anyone else who thought of this horrible vehicle.
