general problems of the 2004 Chevrolet Blazer

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 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.
