When your car breaks down, hazard lights are very important.
I have never bought a new model year automobile. That is because there are always little kinks the manufacturer needs to work out. With good companies like Toyota or Honda they are usually minor.
A buddy of mine bought a brand new Pontiac Grand Am back in the 1990s. They forgot to install the button to turn on the rear defrost. It was totally missing on the dashboard.
Imagine IF this Hummer had broken down while driving through the HOOD or out in the middle of the desert somewhere.
GM has been a sh&ty company since the 1980s when they took gasoline block engines and made them into diesels. They blew up at 25K miles.
