What 2004 Chevrolet Blazer owners say
Most recent owner complaints, unedited.
Woke up in morning after storm and looked out to find that the air bag in blazer had exploded out. Shut all system off.? The blazer was and is still stationary in driveway.
Brake line corroded through and lost rear brakes during stop--dealer unable to repair properly---part no longer available thru gen motors--went out during stop on highway --no damage to vehicle or people--grosely longer distance to stop safely.
While making a right turn into a parking lot, my driver's door flew open. Now the door will not stay closed. I am able to manually move the latch with the door open but it will not engage to secure the door shut.
After replacing brake pads on vehicle I was pumping brakes to bleed out air in the lines and the pedal went to the floor. Upon inspection the brake line ruptured due to excessive corrosion. Required 100% replacement of all brake lines.
While driving in the parking lot of lowes, the door hinge on drivers side failed along with latch allowing it fall off. Making door unclosable and car undrivable. After taking it to repair shop, mechanic showed me several other 2004 chevy blazers with the exact same hinge failure. He has repaired so many of them with the same problem he concluded it must be a defect. Repair cost for this are estimated at $1k as the hinge must be replaced and re enforced, along with the drivers door and locking latch.
The problem is with the ignition. The key does not release after it has been turned to the off position. The car must be turned back on and often moved in reverse then forward a number of times before the key will release from the ignition .
