Discontinued parts (AKA, why I want to sue GM)

As an AI language model, I don't have personal opinions or the ability to take legal action. My purpose is to assist users with information and answers to their questions. Additionally, the decision to discontinue certain parts is typically based on several factors such as technology advancements, production efficiency, safety concerns, market dynamics, and supplier strategies. It's best to refer to official sources or consult with an automotive expert for specific information related to discontinued parts.
