What is wrong with expecting quality on a $70k truck that is standard on a $25k Toyota Corolla?
I wouldn't say any of this is "quality control" issues. The dash isn't loose, or rattling- it's been damaged during shipment or installation.
Surface rust on iron suspension parts is not an indication of quality either. If that axle can go 500K miles with that rust on it- is it still poor quality? What if they put a gold plated axle in there that needed replacing every 20K miles? Would it be quality then?
