GM probably thought their decent sales of the low-priced Chevy Aveo were a good thing. But that just means there are more vehicles to recall after the NHTSA said the 2004 models have rear seat belts that could lock and become unusable. That doesn't sound good. If the belts are twisted the retractor could lock. That sounds really painful. I hadn't heard of this scary story that thankfully panned out OK: In February GM told dealers to stop selling the Aveo after they were involved in five crashes that led to injuries. Luckily the vehicles weren't to blame then.
