The word is clearly composed of 'Auto' (car) and 'Hersteller' (manufacturer). A 'Hersteller' is someone who 'herstellt' (produces/manufactures) something, so literally a car producer.
Dieser Autohersteller ist für seine sportlichen Modelle bekannt.
This car manufacturer is known for its sporty models.
The word belongs to the word family of 'herstellen' (to produce/manufacture) and 'die Herstellung' (production/manufacturing). If you know these words, you can understand many 'Hersteller' words, e.g. 'Möbelhersteller' (furniture manufacturer) or 'Spielzeughersteller' (toy manufacturer).
Die Herstellung eines Autos ist ein komplexer Prozess.
The production of a car is a complex process.
'Autohersteller' (car manufacturer) is often combined with nationalities or size descriptions. Typical examples are 'ein deutscher Autohersteller' (a German car manufacturer), 'ein japanischer Autohersteller' (a Japanese car manufacturer), or 'der größte Autohersteller der Welt' (the largest car manufacturer in the world).

'der Autobauer' and 'der Autohersteller' both usually mean a company that produces cars. In many texts, you can use the two words in a similar way. 'Autohersteller' sounds a little more precise and neutral, especially in news, business, or official texts. 'Autobauer' is also very common, but sounds a bit shorter and more journalistic. Important: 'Autobauer' can rarely also mean a person working in car production, while 'Autohersteller' normally means the company.
