2002 Chevrolet TrailBlazer LTZ 4WD 4dr SUV (4.2L 6cyl 4A)


I drove past the vehicle on the lot for a couple of weeks. I couldn't wait to own it. Unfortunately, it has not been kind to me. Reduced engine light comes on frequently. It has been to the dealership 6 xs to get repaired for that. They replaced numerous electrical components only to tell me they are not sure what the problem is. The driver door module works when it wants to, so sometimes the door doesn't lock. The memory seat works when it wants to. Other than that, replaced suspension parts, and fuel sending unit. All of this happened from 50,000 to 90,000. Can't wait to get rid of it!

Best Features

Love the cup holders and automatic climate control. Leather seats are nice. Love rain sensing wipers! Overall, it is a very comfortable vehicle.

Worst Features

Electrical - Your own technicians can not fix these problems!
