One problem related to power steering hose, piping, and connections has been reported for the 2002 Chevrolet Trailblazer. The most recently reported issues are listed below.
I noticed my vehicle was leaking oil on my driveway so I decided to take it to get it checked out as I was on my way to the lube n oil I went to turn and my power steering locked up almost caused me to crash when I took it to the lube n oil they checked it out and said its not the engine oil its your power steering that's leaking and it has all leaked out. So they took it over to the shop but after 2 hrs waiting they could not figure out what is wrong im very upset that this would happen to a car that is only a few years old I will have to take my vehicle in on Monday to have it checked.
