1. The main factors were because of fuels. Because of an energy crisis up until 2008, the fuel prices skyrocketed which meant that sustainable cars became a priority for buyers. The big three american manufacturers didn't make such vehicles as the US was always a great market for SUVs and other powerful and large cars and sales started to drop and they started losing huge amounts of money because people started buying vehicles that had better fuel consumption or didn't buy at all.
2. At first the government supported the unions who managed to win some and lose some in a series of compromises with company owners. In the end, the government had to give a huge amount of money to the big 3 in order to bail them out since they were almost filing for bankruptcy.
3. The advice would be to start supporting sustainable green cars that are electric powered or biofuel powered and not just make huge SUVs powered by oil. The crisis never would've happened if it had been that way from the beginning.
