2003 Chevrolet TrailBlazer LS 4WD 4dr SUV (4.2L 6cyl 4A)
Overall, a pretty good SUV. Excellent motor and transmission, trouble free after 100K miles. Had all of the axle seals, an air conditioning seal, and a faulty wire harness on the 4WD system replaced, thankfully all under warranty. Considerable wind noise from poor quality door and window seals. Gas mileage is very good for its class. Somewhat "Plain Jane" styling and interior features, which is now typical of GM vehicles. It seems like all of the innovation is with the Japanese brands. Perhaps Michael Lopez's cost cutting measures and squeezing of GM's suppliers have finally caught up with them. The 2007 model is still the same vehicle as the 2002. Why buy another one?
Engine is quiet, powerful, and problem free after 100K miles. No problems with transmission. Seats and ride are very comfortable. Turning radius is very tight, and it handles well, even in rain and snow. Gas mileage is very good for an SUV, 20-22 highway.
Bad electronics and seals. every GM vehicle I've owned has been plagued with these. Fix the wind noise with the door seals. Interior is bland. Redesign this vehicle soon. I'd seriously consider another one, but not if you drain two to three more years out of this design!
