One problem related to brake hoses, lines/piping, and fittings has been reported for the 2005 Chevrolet Trailblazer. The most recently reported issues are listed below.
Leaving parking lot (& wanting to turn onto road) I applied my 2005 Trailblazer ext brakes. My foot & pedal went to floor with no brake at all. Thankfully no cars & going slow enough or I would have hit them. Instead of stopping at end of parking lot, I found myself entering road & seeing trees on other side of road coming up quickly. I grabbed the emergency brake lever. Scared me to death!!! vehicle then taken to repair shop. Shop owner report = hole rubbed in brake line close to driver firewall separating engine from seat area. He further said "been in business for 30+ years and had never seen this before. Seems like a huge design flaw. " rubbing on another line & pinhole there now - which would explain why my a/c was not working on driver side, but working on the pass side. How many other people had an accident? have another (?). . . If gm has known about a problem for yrs on several models: very well documented on internet by hundreds (if not thousands of owners) - why won't ntsaa make gm do something? problem = speed gauge, oil pressure gauge, & radio all of a sudden stop working one day. Then some days they all work, some days only 1 work, some days 2 work??? an equipment malfunction or computer glitch? happened about 75k miles on both my auto & my dad's 2005 chevy pickup. I live in se, he lives in ne. Two areas of us; yet each dealership wanted about $600. 00 to fix it. Called no help available!! searched internet for repair fix, & noticed tons of unhappy owners w/ same problem: gm would not help them pay for this problem - even though it's their equipment problem. Clearly it is a safety issue: no one can tell how fast actually going & led to many accidents & speeding tickets I'm sure! time ntsaa steps in don't you think? then have the brake/ac line rubbing issue - clearly a safety issue & I hope you do something! I still have the brake line.
